    Full Text Available Efforts to find a better adjuvant in regional anaesthesia are underway since long. Aims and objectives are to compare the efficacy and clinical profile of two α-2 adrenergic agonists, dexmedetomidine and clonidine, in epidural anaesthesia with special emphasis on their sedative properties and an ability to provide smooth intra-operative and post-operative analgesia. A prospective randomized study was carried out which included 50 adult female patients between the ages of 44 and 65 years of (American Society of Anaesthesiologists ASAI/II grade who underwent vaginal hysterectomies. The patients were randomly allocated into two groups; ropivacaine + dexmedetomidine (RD and ropivacaine + clonidine (RC, comprising of 25 patients each. Group RD was administered 17 ml of 0.75% epidural ropivacaine and 1.5 μg/kg of dexmedetomidine, while group RC received admixture of 17 ml of 0.75% ropivacaine and 2 μg/kg of clonidine. Onset of analgesia, sensory and motor block levels, sedation, duration of analgesia and side effects were observed. The data obtained was subjected to statistical computation with analysis of variance and chi-square test using statistical package for social science (SPSS version 10.0 for windows and value of P 0.05. Dexmedetomidine is a better neuraxial adjuvant compared to clonidine for providing early onset of sensory analgesia, adequate sedation and a prolonged post-operative analgesia.

    Adjuvants to local anaesthetics for epidural labour analgesia are useful if they reduce side-effects or personnel requirements. Epidural clonidine improves analgesia and provides a significant local anaesthetic-sparing effect. To compare the number of rescue doses administered by the anaesthesiologist when clonidine or sufentanil is added to epidural ropivacaine. A randomised double-blind trial. Cliniques Universitaires Saint-Luc, Université Catholique de Louvain, Brussels, Belgium, from June 2009 to June 2010. One hundred and ninety-five women in labour. Epidural analgesia initiated with 10 ml ropivacaine 0.1%, women randomised to receive patient-controlled epidural analgesia (5 ml demand bolus, 15 min lockout) with ropivacaine 0.1% and sufentanil 0.25 μg ml⁻¹ (RS group; n = 65), or ropivacaine 0.1% and clonidine 1.5 μg ml⁻¹ (RC1.5 group; n = 65) or ropivacaine 0.1% and clonidine 3 μg ml⁻¹ (RC3 group; n = 65). Rescue analgesia was available as needed – 10 ml ropivacaine 0.1% (numerical rating scale neonatal outcomes were similar among the groups. Compared with sufentanil 0.25 μg ml⁻¹, addition of clonidine (1.5 to 3 μg ml⁻¹) to patient-controlled epidural analgesia with ropivacaine 0.1% provided similar labour analgesia and a similar need for anaesthesiologist-administered rescue doses. Clonidine 3 μg ml⁻¹ did not offer any advantage over clonidine 1.5 μg ml⁻¹. The instrumentation rate was higher in both the clonidine groups.

    To determine if the addition of adrenaline, clonidine, or their combination altered the pharmacokinetic profile of levobupivacaine administered via the caudal epidural route in children. Children aged adrenaline 5 mcg · ml(-1) or clonidine 2 mcg · ml(-1) or their combination. Covariate analysis included weight and postnatal age (PNA). Time-concentration profile analysis was undertaken using nonlinear mixed effects models. A one-compartment linear disposition model with first-order input and first-order elimination was used to describe the data. The effect of either clonidine or adrenaline on absorption was investigated using a scaling parameter (Fabs(CLON), Fabs(ADR)) applied to the absorption half-life (Tabs). There were 240 children (median weight 11.0, range 1.9-56.1 kg; median postnatal age 16.7, range 0.6-167.6 months). Absorption of levobupivacaine was faster when mixed with clonidine (Fabs(CLON) 0.60; 95%CI 0.44, 0.83) but slower when mixed with adrenaline (Fabs(ADR) 2.12; 95%CI 1.45, 3.08). The addition of adrenaline to levobupivacaine resulted in a bifid absorption pattern. While initial absorption was unchanged (Tabs 0.15 h 95%CI 0.12, 0.18 h), there was a late absorption peak characterized by a Tabs(LATE) 2.34 h (95%CI 1.44, 4.97 h). The additional use of clonidine with adrenaline had minimal effect on the bifid absorption profile observed with adrenaline alone. Neither clonidine nor adrenaline had any effect on clearance. The population parameter estimate for volume of distribution was 157 l 70 kg(-1). Clearance was 6.5 l · h(-1) 70 kg(-1) at 1-month PNA and increased with a maturation half-time of 1.6 months to reach 90% of the mature value (18.5 l · h(-1) 70 kg(-1)) by 5 months PNA. The addition of adrenaline decreases the rate of levobupivacaine systemic absorption, reducing peak concentration by half. Levobupivacaine concentrations with adrenaline adjuvant were reduced compared to plain levobupivacaine for up to 3.5 hours. Clonidine as an

    Full Text Available For treatment of intra and postoperative pain, no drug has yet been identified that specifically inhibits nociception without associated side effects. Magnesium has antinociceptive effects in animal and human models of pain. The current prospective randomised double-blind study was undertaken to establish the effect of addition of magnesium or clonidine, as adjuvant, to epidural bupivacaine in lower abdominal and lower limb surgeries. A total of 90 American Society of Anesthesiology (ASA grade I and II patients undergoing lower abdominal and lower limb surgeries were enrolled to receive either magnesium sulphate (Group B or clonidine (Group C along with epidural bupivacaine for surgical anaesthesia. All patients received 19 ml of epidural bupivacaine 0.5% along with 50 mg magnesium in group B, 150 mcg clonidine in Group C, whereas in control group (Group A, patients received same volume of normal saline. Onset time, heart rate, blood pressure, duration of analgesia, pain assessment by visual analogue score (VAS and adverse effects were recorded. Onset of anaesthesia was rapid in magnesium group (Group B. In group C there was prolongation of duration of anaesthesia and sedation with lower VAS score, but the incidence of shivering was higher. The groups were similar with respect to haemodynamic variables, nausea and vomiting. The current study establishes magnesium sulphate as a predictable and safe adjunct to epidural bupivacaine for rapid onset of anaesthesia and clonidine for prolonged duration of anaesthesia with sedation.

    local anesthetic effects when epidurally administered. The goal of this study was to evaluate the analgesia and sedation promoted by clonidine or dexmedetomidine associated to epidural ropivacaine, in the postoperative period of subcostal cholecystectomy. METHODS: Forty patients of both gender participated in this randomized double-blind study , aged 18 to 50 years, weighing 50 to 100 kg, physical status ASA I or II, submitted to subcostal cholecystectomy. The subjects were distributed in two groups: Clonidine (CG, receiving clonidine (1 mL = 150 µg associated to 0.75% epidural ropivacaine (20 mL; Dexmedetomidine (DG, receiving dexmedetomidine (2 µg.kg-1 associated to 0.75% epidural ropivacaine (20 mL. Analgesia and sedation were evaluated 2, 6 and 24 hours anesthetic recovery. RESULTS: Both groups present some grade of sedation in the moments 2 and 6 hours , with statistically significant difference between the two moments for the dexmedetomidine group. There has been analgesia in both groups, especially at 2 and 6 hours. There have been statistically significant difference among periods of 2, 6 and 24 hours in the dexmedetomidine group; in the clonidine group, this statistically significant difference was observed between the periods of 2 and 6 hours and between 2 and 24 hours. CONCLUSIONS: Our results allowed to conclude that the association of clonidine or dexmedetomidine to 0.75% ropivacaine induces analgesia and sedation in 2 and 6 hours after anesthetic recovery in patients submitted to subcostal cholecystectomy and that clonidine promotes more prolonged analgesia.

    To determine effects of i.v. administered yohimbine on perineal analgesia, cardiovascular and respiratory activity, and head and pelvic limb position in healthy mares following epidural administration of detomidine hydrochloride solution. 8 healthy mares. Each mare received detomidine hydrochloride (0.06 mg/kg of body weight), administered in the caudal epidural space, followed 61 minutes later by yohimbine (0.05 mg/kg; test) or sterile saline (0.9% NaCl) solution (control), administered i.v., in a randomized, crossover study design with > or = 2 weeks between treatments. Analgesia was determined by lack of sensory perception to electrical stimulation of perineal dermatomes and needle-prick stimulation of coccygeal to 15th thoracic dermatomes. Arterial pH, PaCO2, PaO2, heart and respiratory rates, rectal temperature, arterial blood pressure, and cardiac output were determined, and mares were observed for sweating and urination. Mean scores obtained for test and control groups were compared. Intravenously administered yohimbine significantly reduced mean scores of detomidine-induced perineal analgesia, head ptosis, changes in pelvic limb position, and sweating and diuresis; antagonized detomidine-induced decreases in heart rate and cardiac output; but did not affect detomidine-induced decrease in respiratory rate. Most effects of epidurally administered detomidine, except bradypnea, were antagonized by yohimbine, suggesting that detomidine may influence respiratory rate by mechanisms other than stimulation of alpha2-adrenoceptors, or that yohimbine induces respiratory depressant effects. Yohimbine may be an effective alpha2-adrenoceptor antagonist for all but respiratory depression following epidural administration of detomidine to mares.

    The aim of this study was to investigate the characteristics of the analgesic effect of diclofenac sodium injected epidurally in single or repeated doses and whether tolerance develops in long-term use. A total of 30 rats were included in the study. The rats were anesthetized using intraperitoneal ketamine hydrochloride and an epidural catheter (EC) was inserted at the level of 13th dorsal thoraco-lumbar vertebrae (T13). Eleven rats were excluded from the study. The remaining 19 rats were randomly divided into three groups; Group Control (Group C) (n = 6) received 20 μL normal saline solution (NS) via EC for 10 days; Group Single Dose (Group SD) (n = 6) received 20 μL NS for 9 days and 6 μg diclofenac via EC on 10th day; Group Ten Doses (Group TDs) (n = 7) received 6 μg diclofenac via EC in 20 μL NS for 10 days. On the 10th day, 30 min after epidural diclofenac sodium, 300 mg/kg of 3% acetic acid was injected via intraperitoneal route, and the rats were observed for 30 min and number of writhing reflex (WR) was recorded. The values of total number of Writhing Reflex (WRT) and Writhing reflex per minute(WR/min) were found to be significantly higher in Group C compared with Groups SD and TD (P = 0.009). Single and repeated doses of diclofenac sodium via epidural route have an analgesic effect in a visceral pain model in rats without developing tolerance.

    Full Text Available Background: The aim of the study was to compare the efficacy of clonidine and fentanyl as an additive to ropivacaine given via single shot caudal epidural in pediatric patients for postoperative pain relief. Materials and Methods: In the present double blind study, 90 children of ASA-I-II aged 3-8 years scheduled for infraumblical surgical procedures were randomly allocated to two groups to receive either ropivacaine 0.25% 1 ml/kg+clonidine 2 μg/kg (group I or ropivacaine 0.25% 1 μl/kg+fentanyl 1 μg/kg (group II. Caudal block was performed after the induction of general anesthesia. Postoperatively patients were observed for analgesia, sedation, hemodynamics, and side effects/complications. Results: Both the groups were similar with respect to patient and various block characteristics. The analgesic properties and hemodynamics were also comparable in both groups (P > 0.05. Side effects such as respiratory depression, vomiting bradycardia were significantly less in group I than group II (P < 0.05 ensuing more patient comfort. Conclusions: The analgesic properties of clonidine and fentanyl as additives to ropivacaine in single shot caudal epidural in children are comparable but clonidine offers a more favorable side effect profile. The use of clonidine as additive to ropivacaine in caudal epidural is superior choice to fentanyl because of lack of unwanted side effects and increased patient comfort.

    A report is made of the successful use of oral clonidine for proctalgia fugax by the author on himself. The author, a 30 year old otherwise healthy man, has been having attacks of proctalgia fugax for several years. He had hitherto left the condition untreated. Last year, in a severe attack, he tried oral clonidine 150 micrograms twice a day and found it to be dramatically effective. He was completely relieved in three days and tapered off the drug thereafter. A further attack of proctalgia fugax after a month was again treated successfully with oral clonidine. The presumed aetiology of proctalgia fugax is discussed and the possible mechanism of action of clonidine in this condition is outlined. Further trials of clonidine appear to be worthwhile for this condition which has been described as incurable.

    Full Text Available One of the most severe pains experienced by a woman is that of childbirth. Providing analgesia for labor has always been a challenge more so because of the myths and controversies surrounding labor. It is imperative to understand the pain transmission during various stages of labor in order to select a proper technique for providing labor analgesia. The adverse effects of labor pain are numerous and affect both the mother as well as the fetus. Currently lumbar epidural is considered to be the gold standard technique for labor analgesia. Local anaesthetics like bupivacaine and ropivacaine are commonly used and adjuvants like clonidine, fentanyl and neostigmine have been extensively studied. However, despite being so popular, epidural analgesia is not without complications, with hypotension being the most common. Other complications include accidental dural puncture, infection, intravascular placement, high block and epidural hematoma. Other neuraxial techniques include continuous caudal analgesia, and combined spinal epidural analgesia. The numerous studies investigating the various aspects of this method have also served to dispel various myths surrounding epidural analgesia like increased incidence of cesarean section and instrumental delivery, prolongation of labor and future back pain. The future of labor analgesia lies in the incorporation of ultrasound in identifying the epidural space helping in proper catheter placement. The keywords "labor epidural" in the PUBMED revealed a total of 5018 articles with 574 review articles and 969 clinical trials. The relevant articles along with their references were extensively studied.

    Although routine administration of pharmacologic sedation or analgesia during mechanical ventilation in preterm neonates is not recommended, its use in clinical practice remains common. Alpha-2 agonists, mainly clonidine and dexmedetomidine, are used as adjunctive (or alternative) sedative agents alongside opioids and benzodiazepines. Clonidine has not been systematically assessed for use in neonatal sedation during ventilation. To assess whether clonidine administered to term and preterm newborn infants receiving mechanical ventilation reduces morbidity and mortality rates. To compare the intervention versus placebo, no treatment, and dexmedetomidine; and to assess the safety of clonidine infusion for potential harms.To perform subgroup analyses according to gestational age; birth weight; administration method (infusion or bolus therapy); dose, duration, and route of clonidine administration; and pharmacologic sedation as a co-intervention. We used the standard search strategy of the Cochrane Neonatal Review Group to search the Cochrane Central Register of Controlled Trials (CENTRAL; 2016, Issue 12) in the Cochrane Library, MEDLINE via PubMed (1966 to January 10, 2017), Embase (1980 to January 10, 2017), and the Cumulative Index to Nursing and Allied Health Literature (CINAHL; 1982 to January 10, 2017). We also searched clinical trials databases, conference proceedings, and the reference lists of retrieved articles for randomized controlled trials and quasi-randomized trials. We searched for randomized controlled trials, quasi-randomized controlled trials, and cluster trials comparing clonidine versus placebo, no treatment, or dexmedetomidine administered to term and preterm newborns receiving mechanical ventilation via an endotracheal tube. For the included trial, two review authors independently extracted data (e.g. number of participants, birth weight, gestational age, all-cause death during initial hospitalization, duration of respiratory support, sedation

CONCLUSIONES: La administración de cetamina, clonidina o dexmedetomidina, por vía peridural, reduce el consumo de alfentanil y la concentración inspirada de isoflurano, en el intra-operatorio de cirugía de abdomen superior.BACKGROUND AND OBJECTIVES: Low dose ketamine decreases nociception by blocking NMDA receptor channels. Alpha2-adrenergic receptor activation triggers intense analgesic response. This study aimed at evaluating the effects of epidural ketamine, clonidine and dexmedetomidine, in patients undergoing upper abdominal surgery. METHODS: Participated in this randomized double-blind study 70 patients of both genders, aged 18 to 50 years, physical status ASA I or II, submitted to subcostal cholecystectomy under general anesthesia associated to lumbar epidural anesthesia. Lumbar epidural anesthesia was randomly induced as follows: Control group: 20 mL of 0.75% ropivacaine and 1 mL of 0.9% saline solution (n = 10; Ketamine group: 20 mL of 0.75% ropivacaine and 0.5 mg.kg-1 ketamine (n = 20; Clonidine group: 20 mL of 0.75% ropivacaine and 1 mL clonidine (150 µg (n = 20; Dexmedetomidine group: 20 mL of 0.75% ropivacaine and 2 µg.kg-1 dexmedetomidine (n = 20. Anesthesia was induced with etomidate, alfentanil and rocuronium and was maintained with isoflurane and alfentanil. Analgesia was evaluated by clinical signs and inhalational anesthetic inspired concentration was evaluated by anesthetic gases analysis during surgery. RESULTS: All patients receiving ketamine, clonidine or dexmedetomidine had heart rate and systemic blood pressure decrease and have not required perioperative analgesic complementation. For the same patients, isoflurane inspired concentration varied from 0.5vol% to 1vol% and there were no clinical signs or responses suggesting inadequate anesthetic levels. CONCLUSIONS: Epidural ketamine, clonidine or dexmedetomidine decreases alfentanil consumption and isoflurane inspired concentration in the intraoperative period of upper abdominal

    Full Text Available BACKGROUND Caudal epidural analgesia is one of the most popular regional techniques used in paediatric patients undergoing lower limb, anoperineal and abdominal surgical procedures for postoperative pain relief. The aim of postoperative pain relief is to provide subjective comfort and inhibit trauma-induced nociceptive impulses to blunt autonomic and reflex responses to pain and subsequently to enhance the restoration of function. Caudal epidural analgesia though practiced widely is of short duration even when used with long-acting local anaesthetics. MATERIALS AND METHODS Children of either sex undergoing elective hernia or hydrocele surgery within in the age group of 2-8 years belonging to ASA I and II were included in the study. Informed consent was obtained from the parents before procedure. RESULTS The duration of analgesia in the study group was 10.14 ± 4.69 hrs. and 6.83 ± 0.79 hrs. in the clonidine group and midazolam group. Duration of analgesia in clonidine group was significantly longer when compared to with midazolam group with a p value of <0.05. Sedation Score- There was decrease in heart rate and mean arterial pressure from baseline, but these were under allowable limits of 20%. The patient had pain scores of less than 8 for first 6-8 hrs. The patients were well sedated and were easily arousable. CONCLUSION We conclude that in our study we found that clonidine 8 μg/kg provided good analgesia for a longer duration when compared with midazolam. Clonidine also provided good sedation with minimal haemodynamic variations. This is in agreement with studies conducted to know haemodynamic stability with higher doses of clonidine.

    Full Text Available CONTEXT AND OBJECTIVE: Previous studies have led to speculation that the association between ropivacaine and clonidine might be more effective than ropivacaine alone. We examined the maternal-fetal effects of two pharmacological approaches: a low dose of ropivacaine or a lower dose of ropivacaine plus clonidine for epidural analgesia during labor. DESIGN AND SETTING: Prospective study at Department of Anesthesiology, Faculdade de Medicina de Botucatu, Universidade Estadual Paulista. METHODS: Thirty-two pregnant women in American Society of Anesthesiologists physical status I and II randomly underwent epidural analgesia using 15 ml of ropivacaine 0.125% (R group or 15 ml of ropivacaine 0.0625% plus 75 µg clonidine (RC group. Pain intensity, sensory block level, latency time, motor block intensity, duration of labor analgesia and duration of epidural analgesia were evaluated. The newborns were evaluated using Apgar scores and the Amiel-Tison method (neurological and adaptive capacity score. RESULTS: There were no statistically significant differences between the groups regarding pain score, sensory block level, duration of epidural analgesia or Apgar score. The latency time, duration of labor analgesia and motor block were R group < RC group. The half-hour and two-hour neurological and adaptive capacity scores were higher in the R group. All of the R group newborns and 75% of the RC group newborns were found to be neurologically healthy at the 24-hour examination. RESULTS: There were no statistically significant differences between the groups regarding pain score, sensory block level, duration of epidural analgesia or Apgar score. The latency time, duration of labor analgesia and motor block were R group < RC group. The half-hour and two-hour neurological and adaptive capacity scores were higher in the R group. All of the R group newborns and 75% of the RC group newborns were found to be neurologically healthy at the 24-hour examination

    IMPORTANCE: Acute kidney injury, a common complication of surgery, is associated with poor outcomes and high health care costs. Some studies suggest aspirin or clonidine administered during the perioperative period reduces the risk of acute kidney injury; however, these effects are uncertain...... and each intervention has the potential for harm. OBJECTIVE: To determine whether aspirin compared with placebo, and clonidine compared with placebo, alters the risk of perioperative acute kidney injury. DESIGN, SETTING, AND PARTICIPANTS: A 2 × 2 factorial randomized, blinded, clinical trial of 6905...... patients undergoing noncardiac surgery from 88 centers in 22 countries with consecutive patients enrolled between January 2011 and December 2013. INTERVENTIONS: Patients were assigned to take aspirin (200 mg) or placebo 2 to 4 hours before surgery and then aspirin (100 mg) or placebo daily up to 30 days...

    Full Text Available Hypertension is a risk factor for several cardiovascular diseases and oxidative stress suggested to be involved in the pathophysiology. Antihypertensive drug Clonidine action in ameliorating oxidative stress was not well studied. Therefore, this study investigate the effect of Clonidine on oxidative stress markers and nitric oxide (NO in SHR and nitric oxide synthase inhibitor, N-nitro-L-arginine methyl ester (L-NAME administered SHR. Male rats were divided into four groups [SHR, SHR+Clonidine (SHR-C, SHR+L-NAME, SHR+Clonidine+L-NAME(SHRC+L-NAME]. Rats (SHRC were administered with Clonidine (0.5 mg kg−1 day−1 from 4 weeks to 28 weeks in drinking water and L-NAME (25 mg kg−1 day−1 from 16 weeks to 28 weeks to SHRC+L-NAME. Systolic blood pressure (SBP was measured. At the end of 28 weeks, all rats were sacrificed and in their heart homogenate, oxidative stress parameters and NO was assessed. Clonidine treatment significantly enhanced the total antioxidant status (TAS (P<0.001 and reduced the thibarbituric acid reactive substances (TBARS (P<0.001 and protein carbonyl content (PCO (P<0.05. These data suggest that oxidative stress is involved in the hypertensive organ damage and Clonidine not only lowers the SBP but also ameliorated the oxidative stress in the heart of SHR and SHR+L-NAME.

    DA-9701 is a novel prokinetic agent. In the present study, we investigated the effect of DA-9701 on the motility of the gastric antrum in the normal and clonidine-induced hypomotility in an in vivo animal model. A strain gauge force transducer was sutured on the gastric antrum to measure the contractile activity in rats. A total of 28 rats were subclassified into the 4 groups: (1) the placebo group, (2) the DA-9701 group, (3) the placebo group in the clonidine-pretreated rats, and (4) the DA-9701 group in the clonidine-pretreated rats. After the basal recording, either placebo (3% [w/v] hydroxypropylmethyl cellulose) or DA-9701 was administered. Contractile signals were measured after the administration and after a meal. In the clonidinepretreated rats, either placebo or DA-9701 was administered. Contractile signals were measured after the administration and after a meal. Oral administration of DA-9701 did not significantly alter the motility index of the gastric antrum in the preprandial and postprandial periods, compared with the placebo group. The administration of clonidine decreased the motility index of the gastric antrum in the preprandial and postprandial periods, compared with the administration of placebo. This reduction of the antral motility by the administration of clonidine was not observed in the clonidine-pretreated DA-9701 group. The percentage of the motility index in the postprandial period was significantly greater in the clonidine-pretreated DA-9701 group, compared with the clonidine-pretreated placebo group. DA-9701 improves the hypomotility of the gastric antrum induced by clonidine, suggesting its gastroprokinetic effect in the pathologic condition.

    Full Text Available Objective: Clonidine, an alpha-2 adrenergic agonist, increases the quality of perioperative sedation and analgesia with a few side effects. This study was designed to assess the effect of clonidine premedication on the anesthesics used for elective below knee surgeries in opium abusers and non-abusers. Materials and Methods: In a randomized clinical trial, 160 patients were selected and assigned into four groups. Eighty patients among the opium abusers were divided randomly into clonidine and no clonidine groups, with 40 patients in each, and 80 among the non-abusers were again divided randomly into clonidine and no clonidine groups, with 40 patients in each group. All were anesthetized for elective orthopedic operation using the same predetermined method. The total administered dose of propofol and other variables were compared. Results: The total propofol dose in a decreasing order was as follows: Abuser patients receiving placebo (862 ± 351 mg, non-abuser patients receiving placebo (806 ± 348 mg, abuser patients receiving clonidine (472 ± 175 mg, and non-abuser patients receiving clonidine (448 ± 160 mg. Hence, a statistically significant difference was observed among the four study groups (P value for ANOVA = 0.0001. Conclusion: Adding clonidine as a preoperative medication decreases the patient′s anesthetic needs; this decrease was even more considerable on the anesthetic needs than the effect of opium abuse history on anesthetic dose.

    Full Text Available PURPOSE: To study the safety and efficiency of two anesthetic blockages in hemorroidectomy and the effect of clonidine on analgesia. METHODS: 80 patients were studied, randomly divided into four groups: l (n=19- peridural with a 0,75% ropivacaine; 2 (n=21-peridural with a 0,75% ropivacaine and 150 µg of clonidine; 3 (n=19- subarachnoid with a 0,5% bupivacaine; 4 (n=21- subarachnoid with a 0,5% bupivacaine and 50 µg of clonidine. The intensity of pain was evaluated by the visual analogical scale 8, 12 and 24 hours after surgery. The use of vasoconstrictors on the transoperatory and the amount of analgesics within the 24 hours were registered. RESULTS: The intensity of pain, 8 hours after surgery, was lesser on group 4, and much lesser on group 4 comparing with groups 1 and 2, 12 hours (p=0,022; p=0,001 and 24 hours (p=0,03; p=0,003. The frequency of vasoconstrictors usage on the transoperatory and the analgesics on the post-operatory showed no difference among the groups. There were no anesthetic complications. CONCLUSIONS: The subarachnoid anesthesia with a 0,5% bupivacaine with clonidine, showed better analgesia comparing with the peridural anesthesia with a 0,75% ropivacaine with or without clonidine, however all were safe and efficient. The clonidine aided on the decreasing of pain when subarachnoid anesthesia was used.OBJETIVO: Verificar a segurança e a eficácia de dois bloqueios anestésicos na hemorroidectomia e o efeito da clonidina na analgesia.

    Full Text Available Background and objectives: The intense trauma response triggered by cardiopulmonary bypass can lead to increased morbidity and mortality. The present study evaluated whether clonidine, a drug of the class of α-2 agonists, administered by spinal route, without association with local anesthetics or opioids, reduces this response in cardiac surgery with cardiopulmonary bypass. Method: A total of 27 patients between 18 and 75 years old, divided by non-blinded fashion into a control group (15 and a clonidine group (12, were studied. All patients underwent identical technique of general anesthesia. Then, only the clonidine group received 1 μg kg−1 clonidine by spinal route. Levels of blood glucose, lactate and cortisol were measured at three consecutive times: T1, at the time of installation of invasive arterial pressure; T2, 10 min after the first dose for cardioplegia; and T3, at the time of skin suture; and troponin I values at T1 and T3. The variation of results between T2-T1, T3-T2, and T3-T1 was also evaluated. Results: There was a statistically significant difference only with respect to the variation in blood glucose in the clonidine group: T3-T2, p = 0.027 and T3-T1, p = 0.047. Conclusions: Spinal clonidine at a dose of 1 μg kg−1 did not decrease blood measurements of troponin, cortisol, or lactate. Blood glucose suffered a more moderate variation during the procedure in the clonidine group. This fact, already reported in the literature, requires further investigation to be clarified.

    Exposure to traumatic events can lead to posttraumatic stress disorder (PTSD). Current PTSD treatments typically only produce partial improvement. Hence, there is a need for preclinical research to identify new candidate drugs and to develop novel therapeutic approaches. Animal studies have indicated that fear memories can be weakened by blocking restabilization after retrieval, a process known as reconsolidation. Furthermore, evidence suggests that there are important alterations of the noradrenergic system in PTSD, and hence it may be of interest to study drugs that target this pathway. Here, we investigated the efficacy of clonidine, an α₂-adrenoreceptor agonist, to block reconsolidation in an animal model of persistent traumatic memories. Using an auditory fear conditioning paradigm in rats, we tested the efficacy of clonidine to weaken fear memory retention when administered systemically after retrieval. We evaluated dosage, number of treatments, and specificity in reconsolidation blockade. We found that postretrieval administration of clonidine disrupts fear-related memories in a dose-dependent manner and that two treatments are sufficient for maximal memory impairment. Furthermore, we determined that this effect is long lasting and specific to reconsolidation processes as shown by the selectivity to affect reactivated memories and the absence of spontaneous recovery and of postreactivation short-term memory impairment. Our results demonstrate the efficacy of systemic administration of clonidine following retrieval to persistently disrupt fear memory retention through reconsolidation blockade. This study provides important preclinical parameters for future therapeutic strategies involving clonidine to block reconsolidation as a novel treatment for PTSD symptoms.

    Central deposition of fat is a well-known clinical feature of long-term elevated corticosteroid levels. Rarely described is increased extadural fat within the spinal canal causing compression of the spinal cord and neurologic deficits. Together with 12 previously reported cases, the authors present six additional cases of epidural lipomatosis, review presenting signs and symptoms, and demonstrate the myelographic, CT, and MR findings in this condition. Previously undescribed examples of (1) normal myelography with diagnostic postmyelogram CT, (2) MR imaging of this condition, and (3) cases not associated with exogenous steroid use or morbid obesity are presented. The importance of considering this entity in the appropriate clinical setting is stressed. In particular, if clinical suspicion is high, even in the setting of a normal myelogram, CT or MR imaging should be considered

    The aim of the study was to evaluate the efficacy of clonidine in association with fentanyl as an additive to bupivacaine 0.25% given via single shot caudal epidural in pediatric patients for postoperative pain relief. In the present prospective randomized double blind study, 40 children of ASA-I-II aged 1-5 years scheduled for infraumblical surgical procedures were randomly allocated to two groups to receive either bupivacaine 0.25% (1 ml/kg) with fentanyl 1 μg/kg and clonidine 1μg/kg (group I) or bupivacaine 0.25% (1 ml/kg) with fentanyl 1 μg/kg (group II). Caudal block was performed after the induction of general anesthesia. Postoperatively patients were observed for analgesia, sedation, hemodynamic parameters, and side effects or complications. Both the groups were similar with respect to patient and various block characteristics. Heart rate and blood pressure were not different in 2 groups. Significantly prolonged duration of post-operative analgesia was observed in group I (Pbupivacaine in single shot caudal epidural in children may provide better and longer analgesia after infraumblical surgical procedures.

    Although transforaminal epidural steroid injections under fluoroscopic guidance have become a common mode of treatment of lumbosacral radiculopathy due to herniated disc, the efficacy of steroid with low doses of clonidine has not been compared yet. Comparison of the analgesic efficacy of methylprednisolone alone and with low doses of clonidine for transforaminal injection in lumbosacral radiculopathy. A randomized, double-blind trial. This study was performed at the Pain Clinic under the Department of Anaesthesiology, Jawaharlal Nehru Medical College Hospital, Aligarh Muslim University, Aligarh, India. One hundred and eighty ASA grade I and II patients aged between 18 and 55 years were allocated into groups I, II and III to receive methylprednisolone 60 mg alone or methylprednisolone 60 mg with or without low doses of clonidine (0.5 mcg/kg or 1 mcg/kg) as transforaminal epidural injection. Pain relief and patient's satisfaction were evaluated with the global pain scale. Follow-up visits were advised at 1, 2, 4, 6 and 12 weeks and then at 6 months after injection. Associated complications were recorded. Maximum pain relief was observed at 2 weeks after injection in all the three groups, with no difference in complication rate among the three groups. The most common complication observed was paresthesia in the nerve distribution. Greater than 60% improvement in pain scores was seen in 40% of the patients in group I, 50% of the patients in group II and 75% of the patients in group III. This study is limited by the lack of a placebo group. Adding 1 mcg/kg clonidine to 60 mg methylprednisolone in transforaminal epidural injections provided better pain relief than 60 mg methylprednisolone with 0.5 mcg/kg clonidine or 60 mg methylprednisolone alone in patients suffering from lumbosacral radiculopathy, with practically no significant side-effects.

    Full Text Available Use of vasoconstrictors in local anaesthesia is well known. The study was done on 30 patients who underwent removal of bilateral impacted third molars. The aim of the study was to compare the efficacy of lignocaine with clonidine and lignocaine with adrenaline in respect to onset, duration of anaesthesia, and postoperative analgesia along with hemodynamic stability (systolic blood pressure, diastolic blood pressure, mean arterial pressure, heart rate in intraoral nerve block. The patients were randomly selected of both sexes (male and female between the age group of 18-40 years. Patients received 2 mL of 2% lignocaine with adrenaline (12.5 μg/mL on one side and 2 mL of 2% lignocaine with clonidine (15 μg/mL on the other side at two different appointments. 2 millilitres of drug was administered in both the test group and the control group. Statistically there was significant decrease in intraoperative and postoperative systolic blood pressure, diastolic blood pressure, mean arterial pressure, and heart rate in the lignocaine with clonidine group. The efficacy of clonidine based on visual analog scale was similar to adrenaline. No significant operative complications were observed.

    Pressure waveform analysis provides a reliable confirmatory adjunct to the loss-of-resistance technique to identify the epidural space during thoracic epidural anaesthesia, but its role remains controversial in lumbar epidural analgesia during labour. We performed an observational study in 100 labouring women of the sensitivity and specificity of waveform analysis to determine the correct location of the epidural needle. After obtaining loss-of-resistance, the anaesthetist injected 5 ml saline through the epidural needle (accounting for the volume already used in the loss-of-resistance). Sterile extension tubing, connected to a pressure transducer, was attached to the needle. An investigator determined the presence or absence of a pulsatile waveform, synchronised with the heart rate, on a monitor screen that was not in the view of the anaesthetist or the parturient. A bolus of 4 ml lidocaine 2% with adrenaline 5 μg.ml -1 was administered, and the epidural block was assessed after 15 min. Three women displayed no sensory block at 15 min. The results showed: epidural block present, epidural waveform present 93; epidural block absent, epidural waveform absent 2; epidural block present, epidural waveform absent 4; epidural block absent, epidural waveform present 1. Compared with the use of a local anaesthetic bolus to ascertain the epidural space, the sensitivity, specificity, positive and negative predictive values of waveform analysis were 95.9%, 66.7%, 98.9% and 33.3%, respectively. Epidural waveform analysis provides a simple adjunct to loss-of-resistance for confirming needle placement during performance of obstetric epidurals, however, further studies are required before its routine implementation in clinical practice. © 2017 The Association of Anaesthetists of Great Britain and Ireland.

    Full Text Available It is very important to have proper management in children with Seizure. Electroencephalography (EEG as a diagnostic instrument has a key role in determining the management method of seizure in children. Because of poor cooperation of some children (especially children with attention deficit hyperactivity disorders and developmental disorders in performing EEG, it is the best choice to sedate children before EEG. The aim of present study is to evaluate the sedation efficacy of clonidine in children before EEG. In a randomized clinical trial, 45 children age 2 to 12 with seizure, who referred to Children Hospital of Tabriz University of Medical Sciences and candidate for EEG, were studied. Sedation before EEG induced by 0.5 to 2.0 mg clonidine orally. Sedation score (0 to 5 measured by using eyes condition, response to voice, and response to touch. Successful sedation, EEG performing, and hemodynamic stability were evaluated during sedation. Of all patients, 40 patients (88.88% were sedated successfully, and EEG was performed for all of the children. Mean onset time of clonidine effect was 35.47±13.56 minutes and mean time of that the patients’ level of consciousness back to the level before administrating of clonidine was 77.55±26.87 minutes. Hemodynamic states of all patients were stable during the study, and there were no significant changes in vital sign of patients. In conclusion, clonidine can be considered as a safe alternative medication for sedation for EEG, which is fortunately associated with no significant change in vital signs, which may complicate overall status of patients.

    A new precise and sensitive radioimmunoassay for clonidine has been developed. Synthesis and analysis of the hapten (4-carboxy-clonidine; St 1984) as well as antibody production in rabbits are described in detail. At a final dilution of 1:1000 the resulting immune serum binds 50% of a tritiated clonidine standard containing 1 ng of clonidine. The detection limit of the presented radioimmunoassay for clonidine is 0.1 ng/ml. The coefficient of variation did not exceed 4.3% for any of 7 standard determinations with 5 replicates. There was no relevant crossreactivity of inactive clonidine metabolites apart from 4-OH-clonidine. To avoid any errors from cross-reaction clonidine was selectively and quantitatively extracted into diethylether from unknown plasma samples. Following concentration of the extracts even such low concentrations as 20 pg of clonidine/ml plasma were detectable. With the radioimmunoassay applied in pharmacokinetic studies a maximal clonidine concentration in blood plams of healthy human volunteers was determined to 0.6 ng/ml 1.5 h after oral administration of 150 μg.

    To describe the ultrasonographic anatomy of the caudal lumbar spine in cats and to detect ultrasound (US) signs associated with epidural or intrathecal injection. Prospective, clinical study. Twenty-six client-owned cats. Transverse (position 1) and parasagittal (position 2) two-dimensional US scanning was performed over the caudal lumbar spine in all cats. Midline distances between the identified structures were measured. Cats assigned to epidural injection (group E, n = 16) were administered a bupivacaine-morphine combination confirmed by electrical stimulation. Cats assigned to intrathecal injection (group I, n = 10) were administered a morphine-iohexol combination injected at the lumbosacral level and confirmed by lateral radiography. The total volume injected (0.3 mL kg -1 ) was divided into two equal aliquots that were injected without needle repositioning, with the US probe in positions 1 and 2, respectively. The presence or absence of a burst of color [color flow Doppler test (CFDT)], dural sac collapse and epidural space enlargement were registered during and after both injections. US scanning allowed measurement of the distances between the highly visible structures inside the spinal canal. CFDT was positive for all animals in group E. In group I, intrathecal injection was confirmed in only two animals, for which the CFDT was negative; seven cats inadvertently and simultaneously were administered an epidural injection and showed a positive CFDT during the second aliquot injection, and the remaining animal was administered epidural anesthesia and was excluded from the CFDT data analysis. Dural sac collapse and epidural space enlargement were present in all animals in which an epidural injection was confirmed. US examination allowed an anatomical description of the caudal lumbar spine and real-time confirmation of epidural injection by observation of a positive CFDT, dural sac collapse and epidural space enlargement. © 2016 Association of Veterinary

    Delirium affects 15% of hospitalised patients and is linked with poor outcomes, yet few pharmacological treatment options exist. One hypothesis is that delirium may in part result from exaggerated and/or prolonged stress responses. Dexmedetomidine, a parenterally-administered alpha2-adrenergic receptor agonist which attenuates sympathetic nervous system activity, shows promise as treatment in ICU delirium. Clonidine exhibits similar pharmacodynamic properties and can be administered orally. We therefore wish to explore possible effects of clonidine upon the duration and severity of delirium in general medical inpatients. The Oslo Study of Clonidine in Elderly Patients with Delirium (LUCID) is a randomised, placebo-controlled, double-blinded, parallel group study with 4-month prospective follow-up. We will recruit 100 older medical inpatients with delirium or subsyndromal delirium in the acute geriatric ward. Participants will be randomised to oral clonidine or placebo until delirium free for 2 days (Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria), or after a maximum of 7 days treatment. Assessment of haemodynamics (blood pressure, heart rate and electrocardiogram) and delirium will be performed daily until discharge or a maximum of 7 days after end of treatment. The primary endpoint is the trajectory of delirium over time (measured by Memorial Delirium Assessment Scale). Secondary endpoints include the duration of delirium, use of rescue medication for delirium, pharmacokinetics and pharmacodynamics of clonidine, cognitive function after 4 months, length of hospital stay and need for institutionalisation. LUCID will explore the efficacy and safety of clonidine for delirium in older medical inpatients. ClinicalTrials.gov NCT01956604. EudraCT Number: 2013-000815-26.

    Full Text Available Caudal epidural analgesia with bupivacaine is very popular in paediatric anaesthesia for providing intra- and postoperative analgesia. Several adjuvants have been used to prolong the action of bupivacaine. We evaluated the efficacy of clonidine added to bupivacaine in prolonging the analgesia produced by caudal bupivacaine in children undergoing sub-umbilical surgery. One hundred children, age one to three years, undergoing sub-umbilical surgery, were prospectively randomized to one of two groups: caudal analgesia with 1 ml/kg of 0.25% bupivacaine in normal saline (Group A or caudal analgesia with 1 ml/kg of 0.25% bupivacaine with 1 μg/kg of clonidine in normal saline (Group B. Post-operative pain was assessed for 24 hours using the FLACC scale. The mean duration of analgesia was significantly longer in Group B (593.4 ± 423.3 min than in Group A (288.7 ± 259.1 min; P < 0.05. The pain score assessed using FLACC scale was compared between the two groups, and children in Group B had lower pain scores, which was statistically significant. The requirement of rescue medicine was lesser in Group B. Clonidine in a dose of 1 μg/kg added to 0.25% bupivacaine for caudal analgesia, during sub-umbilical surgeries, prolongs the duration of analgesia of bupivacaine, without any side effects.

    Epidural analgesia is one of the most popular modes of analgesia for child birth. There are controversies regarding adverse effects and safety of epidural analgesia. This study was conducted to study the immediate effects of the maternal epidural analgesia on the neonate during early neonatal phase. A prospective cohort study of 100 neonates born to mothers administered epidural analgesia were compared with 100 neonates born to mothers not administered epidural analgesia in terms of passage of urine, initiation of breast feeding, birth asphyxia and incidence of instrumentation. There was significant difference among the two groups in the passage of urine (P value 0.002) and incidence of instrumentation (P value 0.010) but there was no significant difference in regards to initiation of breast feeding and birth asphyxia. Epidural analgesia does not have any effect on the newborns in regards to breast feeding and birth asphyxia but did have effects like delayed passage of urine and increased incidence of instrumentation.

    Spinal epidural abscess is an uncommon entity, the frequency of which is increasing. They occur spontaneously or as a complication of intervention. The classical triad of fever, back pain and neurological symptoms are not always present. High index of suspicion is key to diagnosis. Any delay in diagnosis and treatment can have significant neurological consequences. We present the case of a previously well man with a one month history of back pain resulting from an epidural abscess.

    The aim of this study was to determine the viability and cardiorespiratory effects of the association of epidural alpha-2 adrenergic agonists and lidocaine for ovariohysterectomy (OH) in bitches. Forty-two bitches were spayed under epidural anesthesia with 2.5 mg/kg body weight (BW) of 1% lidocaine with adrenaline (CON) or in association with 0.25 mg/kg BW of xylazine (XYL), 10 μg/kg BW of romifidine (ROM), 30 μg/kg BW of detomidine (DET), 2 μg/kg BW of dexmedetomidine (DEX), or 5 μg/kg BW of clonidine (CLO). Heart rate (HR), respiratory rate (fR) and arterial pressures were monitored immediately before and every 10 min after the epidural procedure. Blood gas and pH analysis were done before, and at 30 and 60 min after the epidural procedure. Animals were submitted to isoflurane anesthesia if they presented a slightest sign of discomfort during the procedure. Time of sensory epidural block and postoperative analgesia were evaluated. All animals in CON and DEX, 5 animals in ROM and CLO, 4 animals in XYL, and 3 in DET required supplementary isoflurane. All groups, except CLO, showed a decrease in HR. There was an increase in arterial pressures in all groups. Postoperative analgesia lasted the longest in XYL. None of the protocols were totally efficient to perform the complete procedure of OH; however, xylazine provided longer postoperative analgesia than the others. PMID:23277701

    For men the worst aspect of childbirth is witnessing their partner in pain. The aim of this study was to investigate fathers' attitudes towards labor and delivery with and without epidural analgesia. The study was performed using a questionnaire that included yes/no, multiple choice or 6-point ordinal scale answers. Expectant fathers whose partners were nullipara between 36 and 38 weeks of gestation were recruited and the questionnaires were administered on the day after the birth. To investigate paternal anxiety during labor, the State part of the State-Trait Anxiety Inventory was used. The questionnaire was completed by 243 fathers. Sixty percent (145) of the parturients received epidural analgesia and 40% (98) did not. Paternal characteristics were comparable. Fathers whose partners did not receive epidural analgesia felt their presence as troublesome and unnecessary (Pinvolvement (Pfathers whose partners did not or did receive epidural analgesia (Pinvolvement, participation and satisfaction with the experience of childbirth.

    our objective was to determine the association between epidural analgesia and different variables. the effect on newborns of epidural analgesia administered to the mother during labour remains under debate. this association was retrospectively investigated in a cohort of 2399 children born in a Spanish public hospital. Only full-term (>37 weeks of gestation) deliveries were included. Other exclusion criteria were: induced delivery (medical or obstetric indication), elective caesarean section, or the presence of an important pregnancy risk factors (hypertension, diabetes, severe disease, toxaemia, retarded intrauterine growth, chronologically prolonged pregnancy, prolonged membrane rupture (>24 hours), oligoamnios, or polyhydramnios). The Mann-Whitney U test and Fisher׳s exact test were applied to determine the relationship between variables. Apgar index values at one minute and five minutes were slightly but significantly lower in neonates whose mothers had received epidural analgesia. Neonatal intensive care unit admission was significantly more frequent in the epidural versus non-epidural group. Resuscitation was significantly more frequent in the epidural versus non-epidural group. Early breast feeding onset was more frequent in the non-epidural group. The adverse effect of epidural analgesia on early lactation remained significant after adjusting for NICU admission and the need for resuscitation in a logistic regression analysis. Epidural analgesia may have adverse effects on newborns, although the risks are low, and further research is required to elucidate the causal nature of this relationship.

    The addition of subarachnoid clonidine (alpha-agonist) prolongs the analgesia produced by the combination of sufentanil and isobaric bupivacaine in combined labor analgesia(1). The objective of this study was to compare the quality of analgesia and the prevalence of side effects after the addition of subarachnoid clonidine to the anesthetic solution in labor analgesia. After approval by the Ethics Commission, 22 pregnant women in labor were randomly assigned to the subarachnoid administration of either 2.5 mg of 0.5% hyperbaric bupivacaine (CLON/HYPER Group; n = 11) or 2.5 mg of 0.5% isobaric bupivacaine (CLON/ISO Group; n = 11) associated with 2.5 microg of sufentanil and 30 microg of clonidine. Pain, evaluated by the Visual Analogue Scale, heart rate, and mean arterial pressure were assessed every 5 minutes during the first 15 minutes, and then every 15 minutes afterwards until delivery. The prevalence of side effects (nausea, vomiting, pruritus, and sedation) was evaluated. The study was terminated whenever the patient needed supplemental epidural analgesia (pain > 3) or upon delivery of the fetus. The Student t test, Chi-square test, Fisher exact test, and two-way ANOVA for repeated measurements were used in the statistical analysis and a p hyperbaric and isobaric solutions showed similar behavior.

    Joana Nunes

    Full Text Available Abstract Background: There is evidence that administration of a programmed intermittent epidural bolus (PIEB compared to continuous epidural infusion (CEI leads to greater analgesia efficacy and maternal satisfaction with decreased anesthetic interventions. Methods: In this study, 166 women with viable pregnancies were included. After an epidural loading dose of 10 mL with Ropivacaine 0.16% plus Sufentanil 10 µg, parturient were randomly assigned to one of three regimens: A - Ropivacaine 0.15% plus Sufentanil 0.2 µg/mL solution as continuous epidural infusion (5 mL/h, beginning immediately after the initial bolus; B - Ropivacaine 0.1% plus Sufentanil 0.2 µg/mL as programmed intermittent epidural bolus and C - Same solution as group A as programmed intermittent epidural bolus. PIEB regimens were programmed as 10 mL/h starting 60 min after the initial bolus. Rescue boluses of 5 mL of the same solution were administered, with the infusion pump. We evaluated maternal satisfaction using a verbal numeric scale from 0 to 10. We also evaluated adverse, maternal and neonatal outcomes. Results: We analyzed 130 pregnants (A = 60; B = 33; C = 37. The median verbal numeric scale for maternal satisfaction was 8.8 in group A; 8.6 in group B and 8.6 in group C (p = 0.83. We found a higher caesarean delivery rate in group A (56.7%; p = 0.02. No differences in motor block, instrumental delivery rate and neonatal outcomes were observed. Conclusions: Maintenance of epidural analgesia with programmed intermittent epidural bolus is associated with a reduced incidence of caesarean delivery with equally high maternal satisfaction and no adverse outcomes.

    Full Text Available In a prospective, double blind, randomized trial, 120 children, aged 3-8 years,ASAI-II, undergoing strabismus repair were randomly divided into three groups (n = 40 each. Oral clonidine premedication (4gg.kg-1 was administered to all the patients two hours prior to surgery. Soon after induction of anaesthesia, Group G patients were administered intravenous granisetron (40gg.kg-1 , Group D intravenous dexamethasone (150gg.kg-1 and group S received 4ml normal saline. Postoperatively, children were continuously monitored and assessed half-hourly till discharge and then after 24 hours for vomiting and pain. The overall incidence of postoperative emesis was lower (15.4% in the Group G compared with the Group D (21.6% in the first 24 hours (P>0.05. The Group S had a highest incidence of postoperative vomiting ((37% P value < 0.0324 compared to group G. The frequency of early vomiting was highest in the S group. Both G and D groups showed better control of delayed emetic episodes. We observed that in children who were premedicated with clonidine, both IV granisetron or dexamethasone were efficacious in reducing the incidence and severity of POV in day-care strabismus surgery.

    Epidural and intravenous patient-controlled analgesia (PCA) are established methods for pain relief after total hip arthroplasty (THA). Periarticular infiltration is an alternative method that is gaining ground due to its simplicity and safety. Our study aims to assess the efficacy of periarticular infiltration in pain relief after THA. Sixty-three patients undergoing THA under spinal anaesthesia were randomly assigned to receive postoperative analgesia with continuous epidural infusion with ropivacaine (epidural group), intraoperative periarticular infiltration with ropivacaine, clonidine, morphine, epinephrine and corticosteroids (infiltration group) or PCA with morphine (PCA group). PCA morphine provided rescue analgesia in all groups. We recorded morphine consumption, visual analog scale (VAS) scores at rest and movement, blood loss from wound drainage, mean arterial pressure (MAP) and adverse effects at 1, 6, 12, 24 h postoperatively. Morphine consumption at all time points, VAS scores at rest, 6, 12 and 24 h and at movement, 6 and 12 h postoperatively were lower in infiltration group compared to PCA group (p PCA group (p PCA with morphine after THA, providing better pain relief and lower opioid consumption postoperatively. Infiltration seems to be equally effective to epidural analgesia without having the potential side effects of the latter.

  18. Agmatine, an endogenous ligand at imidazoline binding sites, does not antagonize the clonidine-mediated blood pressure reaction

    2002-01-01

    Since agmatine has been identified as a clonidine displacing substance (CDS), the aim of this study was to investigate whether agmatine can mimic CDS-induced cardiovascular reactions in organ bath experiments, pithed spontaneously hypertensive rats (SHR) and anaesthetized SHR.Intravenously-administered agmatine significantly reduced the blood pressure and heart rate of anaesthetized SHR at doses higher than 1 and 3 mg kg−1, respectively. These effects are probably mediated via central mechanisms, since there was an approximate 8 fold rightward shift of the dose-response curve in the pithed SHR (indicating a weakened cardiovascular effect). Moreover, in organ bath experiments, agmatine failed to alter the contractility of intact or endothelium-denuded aortal rings. When agmatine was administered i.c.v. to anaesthetized SHR, blood pressure was increased without any alteration of heart rate, whereas blood pressure was unchanged and heart rate was increased after injection into the 4th brain ventricle. This suggests that haemodynamic reaction patterns after central application are related to distinct influences on central cardiovascular mechanisms.Agmatine reduces noradrenaline release in pithed SHR while α2-adrenoceptors are irreversibly blocked with phenoxybenzamine, but not while I1-binding sites are selectively blocked with AGN192403. This suggests that agmatine may modulate noradrenaline release in the same way that clonidine does, i.e. via imidazoline binding sites; this involves a reduction in sympathetic tone which in turn reduces blood pressure and heart rate.Finally, CDS-like cardiovascular activity appears not to be due to agmatine, since (i) blood pressure in anaesthetized SHR is decreased by agmatine and clonidine, and (ii) agmatine did not antagonize the blood pressure reaction to clonidine in pithed or anaesthetized SHR.

    CT demonstrated posterior fossa epidural hematoma in three patients with head trauma in whom this diagnosis was not clinically apparent. No patient was in stupor or coma and no patient experienced a lucid interval. Only one patient had signs referable to the posterior fossa. Two patients had occipital skull fracture disclosed by plain radiographs. CT revealed a unilateral biconvex hematoma in two cases, and a bilateral hematoma with supratentorial extension in the third. All patients underwent suboccipital craniectomy and recovered. Therapeutic success in these cases was facilitated by early CT and the rapid disclosure of the unsuspected posterior fossa lesions. CT showing contiguous hematoma below and above the tentorium cerebelli after posterior head trauma is highly suggestive of epidural hematoma arising from the posterior fossa. (orig.)

    Pain associated with rib fractures impairs respiratory function and increases pulmonary morbidity. The purpose of this study was to determine how epidural catheters alter mortality and complications in trauma patients. We performed a retrospective study involving adult blunt trauma patients with moderate-to-severe injuries from January 1, 2004 to December 31, 2013. During the 10-year period, 526 patients met the inclusion criteria; 43/526 (8%) patients had a catheter placed. Mean age of patients with epidural catheter (CATH) was higher compared with patients without epidural catheter (NOCATH) (54 vs 48 years, P = 0.021), Injury Severity Score was similar (26 CATH vs 27 NOCATH, P = 0.84), and CATH had higher mean rib fractures (7.4 vs 4.1, P ribs fractured. The epidural cohort had longer hospital LOS and decreased mortality. In contrast to other studies, DVT rates were increased in patients who received epidural catheters.

    Reactivity to stressors and environmental cues, a putative cause of relapse in addiction, may be a useful target for relapse-prevention medication. In rodents, alpha-2 adrenergic agonists such as clonidine block stress-induced reinstatement of drug seeking, but not drug cue-induced reinstatement. The objective of this study is to test the effect of clonidine on stress- and cue-induced craving in human cocaine users. Healthy, non-treatment-seeking cocaine users (n = 59) were randomly assigned to three groups receiving clonidine 0, 0.1, or 0.2 mg orally under double-blind conditions. In a single test session, each participant received clonidine or placebo followed 3 h later by exposure to two pairs of standardized auditory-imagery scripts (neutral/stress and neutral/drug). Subjective measures of craving were collected. Subjective responsivity ("crave cocaine" Visual Analog Scale) to stress scripts was significantly attenuated in the 0.1- and 0.2-mg clonidine groups; for drug-cue scripts, this attenuation occurred only in the 0.2-mg group. Other subjective measures of craving showed similar patterns of effects but Dose × Script interactions were not significant. Clonidine was effective in reducing stress-induced (and, at a higher dose, cue-induced) craving in a pattern consistent with preclinical findings, although this was significant on only one of several measures. Our results, though modest and preliminary, converge with other evidence to suggest that alpha-2 adrenergic agonists may help prevent relapse in drug abusers experiencing stress or situations that remind them of drug use.

    Anaphylaxis during image-guided interventional procedures is a rare but potentially fatal event. Anaphylaxis to iodinated contrast is an established and well-recognized adverse effect. However, anaphylaxis to some of the other frequently administered medications given during interventional procedures, such as corticosteroids, is not common knowledge. During caudal epidural injection, iodinated contrast is used to confirm needle placement in the epidural space at the level of the sacral hiatus. A combination of corticosteroid, local anesthetic, and saline is subsequently injected. We describe a very rare case of anaphylaxis to a component of the steroid medication instilled in the caudal epidural space.

    Objective: The toxic and lethal doses of clonidine in children are unclear. This study was designed to determine whether data from the American Association of Poison Control Centers Toxic Exposure Surveillance System (TESS) could be utilized to determine a dose-response relationship for pediatric clonidine exposure. Methods: 3458 single-substance clonidine exposures in children <6 years of age reported to TESS from January 2000 through December 2003 were examined. Dose ingested, age, and medical outcome were available for 1550 cases. Respiratory arrest cases (n = 8) were classified as the most severe of the medical outcome categories (Arrest, Major, Moderate, Mild, and No effect). Exposures reported as a 'taste or lick' (n = 51) were included as a dose of 1/10 of the dosage form involved. Dose ranged from 0.4 to 1980 (median 13) μg/kg. Weight was imputed based on a quadratic estimate of weight for age. Dose certainty was coded as exact (26% of cases) or not exact (74%). Medical outcome (response) was examined via logistic regression using SAS JMP (release 5.1). Results: The logistic model describing medical outcome (P < 0.0001) included Log dose/kg (P 0.0000) and Certainty (P = 0.045). Conclusion: TESS data can provide the basis for a statistically sound description of dose-response for pediatric clonidine poisoning exposures

    Background The management of withdrawal absorbs substantial clinical efforts in opioid dependence (OD). The real challenge lies in improving current pharmacotherapies. Although widely used, clonidine causes problematic adverse effects and does not alleviate important symptoms of opioid withdrawal, alone or in combination with the opioid antagonist naltrexone. Very low-dose naltrexone (VLNTX) has been shown to attenuate withdrawal intensity and noradrenaline release following opioid agonist taper, suggesting a combination with clonidine may result in improved safety and efficacy. Objectives We investigated the effects of a VLNTX–clonidine combination in a secondary analysis of data from a double-blind, randomized opioid detoxification trial. Methods Withdrawal symptoms and treatment completion were compared following VLNTX (.125 or .25 mg/day) and clonidine (.1–.2 mg q6h) in 127 individuals with OD undergoing 6-day methadone inpatient taper at a community program. Results VLNTX was more effective than placebo or clonidine in reducing symptoms and signs of withdrawal. The use of VLNTX in combination with clonidine was associated with attenuated subjective withdrawal compared with each medication alone, favoring detoxification completion in comparison with clonidine or naltrexone placebo. VLNTX/clonidine was effective in reducing symptoms that are both undertreated and well controlled with clonidine treatment and was not associated with significant adverse events compared with other treatments. Conclusions and Scientific Significance Preliminary results elucidate neurobiological mechanisms of OD and support the utility of controlled studies on a novel VLNTX + low-dose clonidine combination for the management of opioid withdrawal.

    To determine the effect of epidural analgesia on biochemical markers of stress, plasma oxytocin concentrations and frequency of uterine contractions during the first stage of labour. Nine nulliparous women, in spontaneous labour, with a singleton fetus and cervical dilatation < or = 5 cm were enrolled. Epidural bupivacaine 0.25% (range 10-14 ml) was administered and bilateral sensory blockade to ice (T8-L4) achieved. Blood samples were collected before the epidermal block and every 10 min for one hour after the block was achieved for the measurement of plasma beta-endorphin, cortical, glucose, lactate and oxytocin concentrations. No exogenous oxytocin was given. Intensity of pain was assessed at the time of the blood sampling using a 10 cm visual analogue scale (VAS). The frequency of uterine contractions was recorded for 60 min before and after the epidural block. There was a decrease in plasma beta-endorphin and cortisol concentrations after epidural block (P < 0.01). There were no changes in plasma glucose and lactate concentrations. The mean VAS for pain decreased 10 min after epidural block was achieved and remained < 2 throughout the study period (P < 0.001). Mean plasma oxytocin concentrations did not change. The frequency of uterine contractions before and after the epidural block was similar. The metabolic stress response to the pain of labour was attenuated by epidural analgesia. In contrast, plasma oxytocin concentration and frequency of uterine contractions were unaffected by the attenuation of metabolic stress response.

    The study evaluated duration and depth of the local infiltration anesthesia by articaine with different combinations of epinephrine and clonidine : articaine (4%) + epinephrine (1: 200 000), articaine (4%) + clonidine (1:100 000), articaine (4%) + epinephrine (1:200 000) + clonidine (1:100 000), articaine (4%) + epinephrine (1: 400 000) + clonidine (1:100, 000) in pediatric dental practice. It was revealed that the replacement of the vasoconstrictor epinephrine on clonidine associated with reduced depth and duration of analgesia. This increased efficiency is provided by inclusion of epinephrine (1:200 000), and clonidine (1:100 000) into anesthetic solution, which provided statistically significant increase in depth and duration of anesthesia.

    1983-03-01

    The effects of clonidine hydrochloride, an agent effective in suppressing other types of flushing reactions, were investigated in patients with erythematotelangiectatic rosacea. Clonidine hydrochloride, 0.05 mg, was given orally twice daily for two weeks. Mean arterial BP was not altered during clonidine treatment. Flushing reactions provoked with water at 60 degrees C, red wine, and chocolate were not suppressed during clonidine treatment. Clonidine did lead to malar hypothermia. It may be that any treatment benefit obtained from the reduction in vascular reactivity by clonidine in rosacea is offset by the malar hypothermia.

    1998-09-01

    The potential effects of epidural analgesia on the progress and outcome of labour have been the subject of lasting controversy. Retrospective reviews indicate that epidurals are associated with longer labours and/or an increase in the incidence of instrumental or operative delivery. Similar results were obtained in non-randomized prospective studies. None of them established a causal relationship, because without randomization the selection bias cannot be ruled out. Other factors, such as premature rupture of membranes and maternal socioeconomic status, may affect the outcome of labour. It was also reported that introduction of the on-demand epidural service did not increase the primary caesarean section rate. The few prospective randomized studies are contradictory and not very reliable owing to small patient populations and high cross-over rates. There is, however, unanimity among the authors regarding the superiority of pain relief provided by epidural blocks over systemically administered opioids.

    Several animal studies showed beneficial effects of thoracic epidural anesthesia (TEA) in hippocampal, mesenteric and myocardial IR injury (2-4). In this study, we investigated the effects of epidural bupivacaine on hepatic ischemia reperfusion injury in a rat model. Eighteen rats were randomly divided into three groups each containing 6 animals. The rats in Group C had sham laparotomy. The rats in the Group S were subjected to liver IR through laparotomy and 20 mcg/kg/h 0.9% NaCl was administered to these rats via an epidural catheter. The rats in the Group B were subjected to liver IR and were given 20 mcg/kg/h bupivacaine via an epidural catheter. Liver tissue was harvested for MDA analysis, apoptosis and histopathological examination after 60 minutes of ischemia followed by 360 minutes of reperfusion. Blood samples were also collected for TNF-α, IL-1β, AST and ALT analysis. The AST and ALT levels were higher in ischemia and reperfusion group, which received only normal saline via the thoracic epidural catheter, compared to the sham group. In the ischemia reperfusion group, which received bupivacaine via the epidural catheter, IL-1 levels were significantly higher than in the other groups. TNF-α levels were higher in the Groups S and B compared to the sham group. Bupivacaine administration induced apoptosis in all animals. These results showed that thoracic epidural bupivacaine was not a suitable agent for preventing inflammatory response and lipid peroxidation in experimental hepatic IR injury in rats. Moreover, epidural bupivacaine triggered apoptosis in hepatocytes. Further research is needed as there are no studies in literature investigate the effects of epidural bupivacaine on hepatic ischemia reperfusion injury (Tab. 3, Fig. 3, Ref. 34).

    The behavior of arterial blood pressure in postpartum of women with hypertension and pregnancy and the best treatment for very high blood pressure in this period still need evidence. The Cochrane systematic review assessing prevention and treatment of postpartum hypertension found only two trials (120 patients) comparing hydralazine with nifedipine and labetalol for the treatment of severe hypertension and did not find enough evidence to know how best to treat women with hypertension after birth. Although studies have demonstrated the effectiveness of treatment with captopril, side effects were reported. Because of these findings, new classes of antihypertensive drugs began to be administered as an alternative therapy. Data on the role of clonidine in this particular group of patients, its effects in the short and long term are still scarce in the literature. To determine the effectiveness of clonidine, compared to captopril, for the treatment of postpartum very high blood pressure in women with hypertension in pregnancy. The study is a triple blind randomized controlled trial including postpartum women with diagnosis of hypertension in pregnancy presenting very high blood pressure, and exclusion criteria will be presence of heart disease, smoking, use of illicit drugs, any contraindication to the use of captopril or clonidine and inability to receive oral medications.Eligible patients will be invited to participate and those who agree will be included in the study and receive captopril or clonidine according to a random list of numbers. The subjects will receive the study medication every 20 minutes until blood pressure is over 170 mmHg of systolic blood pressure and 110 mmHg diastolic blood pressure. A maximum of six pills a day for very high blood pressure will be administered. In case of persistent high blood pressure levels, other antihypertensive agents will be used.During the study the women will be subject to strict control of blood pressure and urine

    This systematic review and meta-analysis evaluates evidence for seven risk factors associated with failed conversion of labor epidural analgesia to cesarean delivery anesthesia. Online scientific literature databases were searched using a strategy which identified observational trials, published between January 1979 and May 2011, which evaluated risk factors for failed conversion of epidural analgesia to anesthesia or documented a failure rate resulting in general anesthesia. 1450 trials were screened, and 13 trials were included for review (n=8628). Three factors increase the risk for failed conversion: an increasing number of clinician-administered boluses during labor (OR=3.2, 95% CI 1.8-5.5), greater urgency for cesarean delivery (OR=40.4, 95% CI 8.8-186), and a non-obstetric anesthesiologist providing care (OR=4.6, 95% CI 1.8-11.5). Insufficient evidence is available to support combined spinal-epidural versus standard epidural techniques, duration of epidural analgesia, cervical dilation at the time of epidural placement, and body mass index or weight as risk factors for failed epidural conversion. The risk of failed conversion of labor epidural analgesia to anesthesia is increased with an increasing number of boluses administered during labor, an enhanced urgency for cesarean delivery, and care being provided by a non-obstetric anesthesiologist. Further high-quality studies are needed to evaluate the many potential risk factors associated with failed conversion of labor epidural analgesia to anesthesia for cesarean delivery.

    Full Text Available Background. Posterior fossa epidural hematomas represent 7-14% of all traumatic intracranial epidural hematomas. They are most frequently encountered posttraumatic mass lesions in the posterior fossa. The aim of this study was to identify clinical features that could lead to the early diagnosis of posterior fossa epidural hematoma. Methods. Between 1980 and 2002, 28 patients with epidural hematoma of the posterior fossa were operated on at the Institute for Neurosurgery, Belgrade. Clinical course neuroradiological investigations, and the results of surgical treatment of the patients with posterior fossa epidural hematomas were analyzed retrospectively. Results. Almost two thirds of patients were younger than 16 years of age. In 20 cases injury was caused by a fall, in 6 cases by a traffic accident, and in 2 by the assault. Clinical course was subacute or chronic in two thirds of the patients. On the admission Glasgow Coma Scale was 7 or less in 9 injured, 8-14 in 14 injured, and 15 in 5 injured patients. Linear fracture of the occipital bone was radiographically evident in 19 patients, but was intraoperatively encountered in all the patients except for a 4-year old child. In 25 patients the diagnosis was established by computer assisted tomography (CAT and in 3 by vertebral angiography. All the patients were operated on via suboccipital craniotomy. Four injured patients who were preoperatively comatose were with lethal outcome. Postoperatively, 24 patients were with sufficient neurologic recovery. Conclusion. Posterior fossa epidural hematoma should be suspected in cases of occipital injury, consciousness disturbances, and occipital bone fracture. In such cases urgent CAT-scan is recommended. Early recognition early diagnosis, and prompt treatment are crucial for good neurological recovery after surgery.

    Full Text Available Background: There is evidence that administration of a programmed intermittent epidural bolus (PIEB compared to continuous epidural infusion (CEI leads to greater analgesia efficacy and maternal satisfaction with decreased anesthetic interventions. Methods: In this study, 166 women with viable pregnancies were included. After an epidural loading dose of 10 mL with Ropivacaine 0.16% plus Sufentanil 10 μg, parturient were randomly assigned to one of three regimens: A – Ropivacaine 0.15% plus Sufentanil 0.2 μg/mL solution as continuous epidural infusion (5 mL/h, beginning immediately after the initial bolus; B – Ropivacaine 0.1% plus Sufentanil 0.2 μg/mL as programmed intermittent epidural bolus and C – Same solution as group A as programmed intermittent epidural bolus. PIEB regimens were programmed as 10 mL/h starting 60 min after the initial bolus. Rescue boluses of 5 mL of the same solution were administered, with the infusion pump. We evaluated maternal satisfaction using a verbal numeric scale from 0 to 10. We also evaluated adverse, maternal and neonatal outcomes. Results: We analyzed 130 pregnants (A = 60; B = 33; C = 37. The median verbal numeric scale for maternal satisfaction was 8.8 in group A; 8.6 in group B and 8.6 in group C (p = 0.83. We found a higher caesarean delivery rate in group A (56.7%; p = 0.02. No differences in motor block, instrumental delivery rate and neonatal outcomes were observed. Conclusions: Maintenance of epidural analgesia with programmed intermittent epidural bolus is associated with a reduced incidence of caesarean delivery with equally high maternal satisfaction and no adverse outcomes. Resumo: Justificativa: Há evidências de que a administração de um bolus epidural intermitente programado (BEIP comparada à infusão epidural contínua (IEC resulta em maior eficácia da analgesia e da satisfação materna, com redução das intervenções anestésicas.

    lntrathoracic extramedullary haematopoiesis is a rare condition. Involvement of the spinal epidural space with haematopoietic tissue is rather unusual. A 31-year-old-man with a known diagnosis of β-thalassaemia was referred with focal back pain. Magnetic resonance imaging revealed diffuse bone-marrow changes, thoracic paraspinal masses and lobulated epidural masses, suggesting extramedullary haemopoiesis. The patient was treated with radiotherapy and blood transfusions. Follow-up MRI was performed for evaluation efficacy of the treatment. Copyright (2002) Blackwell Science Pty Ltd

    Incomplete anaesthesia is a major clinical problem both in single spinal and in single epidural anaesthesia. The clinical efficacy of epidural anaesthesia with augmentation (aEA) and combined epidural and spinal anesthesia (CSE) for cesarean section was investigated in a prospective randomized study on 45 patients. Anaesthesia extending up to Th5 was aimed for. Depending on the patient's height, epidural anaesthesia was administered with a dose of 18-22 ml 0.5% bupivacaine and spinal anaesthesia with a dose of 11-15 mg 0.5% bupivacaine. Augmentation was carried out in all cases in epidural anaesthesia, initially with 7.5 ml 1% Lidocaine with epinephrine 1:400,000, raised by 1.5 ml per missing segment. The epidural reinjection in CSE was carried out as necessary with 9.5-15 ml 1% lidocaine with epinephrine, depending on the height and difference from the segment Th5. The extension of anaesthesia achieved in epidural anaesthesia after an initial dose of 101.8 mg bupivacaine and augmenting dose of 99 mg lidocaine reached the segment Th5. The primary spinal anaesthesia dose up to 15 mg corresponding to height led to a segmental extension to a maximum of Th3 under CSE. Augmentation was necessary in 13 patients; in 5 cases because of inadequate extent of anaesthesia and 8 cases because of pain resulting from premature reversion. The augmenting dose required was 13.9 ml. Readiness for operation was attained after 19.8 min (aEA) and after 10.5 min (CSE). No patient required analgesics before delivery. The additional analgesic requirement during operation was 63.6% (aEA) and 39.1% (CSE). Taking into account pain in the area of surgery, the requirement of analgesics was 50% (aEA) vs. 17.4% (CSE). Antiemetics were required in 18.2 (aEA) and in 65.2% (CSE). The systolic blood pressure fell by 17.7% (aEA) and in 30.3% (CSE). The minimum systolic pressure was observed after 13.4 min in aEA, and after 9.5 min in CSE. The APGAR score and the umbilical pH did not show any

    2017-07-01

    Conclusion: Addition of clonidine 2mcg/kg to 28 ml of 0.5% bupivacaine in brachial plexus blocks results in a faster onset, increased duration of block and longer postoperative pain relief when compared to bupivacaine alone. These advantages are not observed when the same dose of clonidine is injected intravenously.

    In this paper three acute cases and two subacute cases are reported. CT findings in acute cases show two different types. ''Type I'' shows crescent or lenticular high density area which is not enhanced after contrast infusion. ''Type II'' shows lenticular low density area with membranous high density region in its medial side after contrast infusion. In subacute cases plain CT scan shows lenticular iso or low density area with membranous high density region in its medial side. Forty five cases of posterior fossa epidural hematoma in the review of literature of this country are discussed. Disturbances of the consciousness are the most predominant symptoms in acute cases, while in subacute cases cerebellar signs, vomiting, headache and choked disc are noted. Angiographical examinations may not always be valuable in collecting the direct information of the existence of the epidural hematoma. Liquor cavity in the posterior fossa which is thought to serve as a buffer action of hematoma is about 20 ml, so we discuss about the volume of hematoma, especially of 20 ml, associated with clinical course and prognosis. Volume of epidural hematoma is one of the most important factors affecting clinical course and prognosis. In summary of these our experiences, we again emphasize the value of CT scan as the rapid, noninvasive, accurate radiological examination in the diagnosis of traumatic posterior fossa epidural hematoma.

    The clinical features and sequential changes of CT findings in children with acute epidural hematoma were correlated with the patient's age. Of the 373 children admitted for head injury during the past 8 years, 61 had an acute traumatic intra-cranial hematoma, and 38 of these had acute epidural hematoma. None of the patients with acute epidural hematoma was under 2 years of age, 15 were 2-6 years old, and 23 were 7-15 years old. In the pre-school group, the numbers of boys and girls were approximately equal, but in the older group boys outnumbered girls. Epidural hematoma was most often parietal (12 patients). Nine patients had posterior fossa hematomas; 30 (78.9%) had skull fractures, and the incidence was not related to the patient's age. In 28 of the 38 patients, CT scans were examined repeatedly for 24 hours. In 15 of them (53.6%), the size of the hematoma increased. In school-aged children, the hematoma tended to be larger than in pre-school children. In four patients with pneumocephalus, the hematoma increased in size. Eleven of the 13, whose hematomas did not increase in size, had skull fractures. (author)

    It is often difficult to differentiate each pathologic entity among various spinal epidural masses on the radiologic basis. We retrospectively analysed radiologic findings of 67 cases of pathologically proven spinal epidural mass to find out any specific findings of each epidural mass. The results are as follows : 1. Of 67 cases, metastasis (16 cases), epidural abscess (15 cases), neurogenic tumor (16 cases) and meningioma (8 cases) are most common. The others consist of epidural angioma (3 cases), vertebral hemangioma (2 cases), chondrosarcoma (2 cases), fibrosarcoma (1 case), eosinophilic granuloma (1 case), lymphoma (1 case), lipoma (1 case) and lymphoid hyperplasia (1 case). 2. Destruction of the adjacent bone was commonly associated with the epidural mass in metastasis (75%) and epidural abscess (67%). It was also noted in 2 cases of chondrosarcoma, 1 fibrosarcoma and 1 eosinophilic granuloma. 3. Pressure erosion of adjacent bone was demonstrated in neurogenic tumor (75%) and meningioma (25%). 4. Narrowing of intervertebral space was seen in only 27% of epidural abscess. 5. The paraspinal tumor was associated in 67% of metastasis, 80% of epidural abscess, 75% of neurogenic tumor, 33% of meningioma. It was also seen in 2 cases of chondrosarcoma, 1 fibrosarcoma and 1 eosinophilic granuloma. 6. The intradural tumor was associated in 50% of neurogenic tumor and 67% of meningioma. 7. On axial CT image, most of the epidural mass shows eccentric location with displacing dural sac to the opposite side. The diseases that occasionally show encircling location are metastasis, epidural abscess, vertebral hemangioma, chondrosarcoma, eosinophilic granuloma, and lymphoma. Neurogenic tumor only shows multicentric location. 8. The disease extent more than height of one vertebral body was seen in 80% of epidural abscess, 58% of neurogenic tumor, 100% of epidural angioma. It was also seen in 2 cases of chondrosarcoma, 1 fibrosarcoma, 1 eosinophilic granuloma, 1 lymphoma, 1

    To investigate physiological and antinociceptive effects of electroacupuncture (EA) with lidocaine epidural nerve block in goats. Prospective experimental trial. Forty-eight hybrid male goats weighing 27 ± 2 kg. The goats were randomly assigned to six groups: L2.2, epidural lidocaine (2.2 mg kg -1 ); L4.4, epidural lidocaine (4.4 mg kg -1 ); EA; EA-L1.1, EA with epidural lidocaine (1.1 mg kg -1 ); EA-L2.2, EA with epidural lidocaine (2.2 mg kg -1 ); and EA-L4.4, EA with epidural lidocaine (4.4 mg kg -1 ). EA was administered for 120 minutes. Epidural lidocaine was administered 25 minutes after EA started. Nociceptive thresholds of flank and thigh regions, abdominal muscle tone, mean arterial pressure (MAP), heart rate (HR), respiratory frequency (f R ) and rectal temperature were recorded at 30, 60, 90, 120, 150 and 180 minutes. Lidocaine dose-dependently increased nociceptive thresholds. There were no differences in nociceptive thresholds between L4.4 and EA from 30 to 120 minutes. The threshold in EA-L2.2 was lower than in EA-L4.4 from 30 to 120 minutes, but higher than in EA-L1.1 from 30 to 150 minutes or in L4.4 from 30 to 180 minutes. The abdominal muscle tone in EA-L2.2 was higher at 30 minutes, but lower at 90 and 120 minutes than at 0 minutes. There were no differences in muscle tone between L4.4 and L2.2 or EA-L4.4, and between any two of the three EA-lidocaine groups from 0 to 180 minutes. The f R and HR decreased in L4.4 at 60 and 90 minutes compared with 0 minutes. No differences in f R , HR, MAP and temperature among the groups occurred from 30 to 180 minutes. EA combined with 2.2 mg kg -1 epidural lidocaine provides better antinociceptive effect than 4.4 mg kg -1 epidural lidocaine alone in goats. EA provided antinociception and allowed a decrease in epidural lidocaine dose. Copyright © 2017 Association of Veterinary Anaesthetists and American College of Veterinary Anesthesia and Analgesia.

  7. Morphine and clonidine combination therapy improves therapeutic window in mice: synergy in antinociceptive but not in sedative or cardiovascular effects.

    Full Text Available Opioids are used to manage all types of pain including acute, cancer, chronic neuropathic and inflammatory pain. Unfortunately, opioid-related adverse effects such as respiratory depression, tolerance, physical dependence and addiction have led to an underutilization of these compounds for adequate pain relief. One strategy to improve the therapeutic utility of opioids is to co-administer them with other analgesic agents such as agonists acting at α2-adrenergic receptors (α2ARs. Analgesics acting at α2ARs and opioid receptors (ORs frequently synergize when co-administered in vivo. Multimodal analgesic techniques offer advantages over single drug treatments as synergistic combination therapies produce analgesia at lower doses, thus reducing undesired side effects. This inference presumes, however, that the synergistic interaction is limited to the analgesic effects. In order to test this hypothesis, we examined the effects of α2AR/OR combination therapy in acute antinociception and in the often-undesired side effects of sedation and cardiovascular depression in awake unrestrained mice. Morphine, clonidine or their combination was administered by spinal or systemic injection in awake mice. Antinociception was determined using the warm water tail flick assay (52.5°C. Sedation/motor impairment was evaluated using the accelerating rotarod assay and cardiovascular function was monitored by pulse oximetry. Data were converted to percent maximum possible effect and isobolographic analysis was performed to determine if an interaction was subadditive, additive or synergistic. Synergistic interactions between morphine and clonidine were observed in the antinociceptive but not in the sedative/motor or cardiovascular effects. As a result, the therapeutic window was improved ∼200-fold and antinociception was achieved at non-sedating doses with little to no cardiovascular depression. In addition, combination therapy resulted in greater maximum analgesic

    To compare the analgesic efficacy of buprenorphine plus detomidine with that of morphine plus detomidine when administered epidurally in horses undergoing bilateral stifle arthroscopy. Prospective, randomized, blinded clinical trial. Twelve healthy adult horses participating in an orthopedic research study. Group M (n = 6) received morphine (0.2 mg kg(-1)) and detomidine (0.15 mg kg(-1)) epidurally; group B (n = 6) received buprenorphine (0.005 mg kg(-1)) and detomidine (0.15 mg kg(-1)) epidurally. Horses received one of two epidural treatments following induction of general anesthesia for bilateral stifle arthroscopy. Heart rate (HR), mean arterial blood pressure (MAP), end-tidal CO(2) (Pe'CO(2)), and end-tidal isoflurane concentrations (E'Iso%) were recorded every 15 minutes following epidural administration. Post-operative assessment was performed at 1, 2, 3, 6, 9, 12, and 24 hours after standing; variables recorded included HR, respiratory rate (f(R)), abdominal borborygmi, defecation, and the presence of undesirable side effects. At the same times post-operatively, each horse was videotaped at a walk and subsequently assigned a lameness score (0-4) by three ACVS diplomates blinded to treatment and who followed previously published guidelines. Nonparametric data were analyzed using Wilcoxon's rank-sum test. Inter- and intra-rater agreement were determined using weighted kappa coefficients. Statistical significance was set at p detomidine injected epidurally produced analgesia similar in intensity and duration to that of morphine plus detomidine injected epidurally.

    The maximum dose of clonidine used was70 μg. The meantime from injection to regression of the level of sensory analgesia by two segments was longer in the Clonidine group than in Control group (P< 0.001. The duration of motor blockade was longer in Clonidine group than in Control group (P< 0.05. There was also a significant difference in the duration of analgesia between the two groups (P< 0.001. The rescue analgesia was required earlier in the Control group(mean 223 min compared to the Clonidine group(mean614 min. The number of injections of diclofenacin24 hours was higher for Control group (mean2.66 than Clonidine group (mean 1.16 (P < 0.05. The patients in the Clonidine group had a significant fall in mean arterial pressure and heart rate and were more sedated than those in Control group, however, no therapeutic interventions needed. We concluded that addition of clonidine to bupivacaine in the dose of 1μg.kg -1 significantly increases the duration of spinal analgesia as compared to bupivacaine alone with clinically insignificant influence on haemodynamic parameters and level of sedation.

    There are limited reports of adult clonidine overdose. We aimed to describe the clinical effects and treatment of clonidine overdose in adults. This was a retrospective review of a prospective cohort of poisoned patients who took clonidine overdoses (>200 μg). Demographic information, clinical effects, treatment, complications (central nervous system and cardiovascular effects) and length of stay (LOS) were extracted from a clinical database or medical records. From 133 admissions for clonidine poisoning (1988-2015), no medical record was available in 14 and 11 took staggered ingestions. Of 108 acute clonidine overdoses (median age 27 years; 14-65 years; 68 females), 40 were clonidine alone ingestions and 68 were clonidine with co-ingestants. Median dose taken was 2100 μg (interquartile range [IQR]: 400-15,000 μg). Median LOS was 21h (IQR: 14-35 h) and there were no deaths. Glasgow coma score [GCS] central nervous system depression and bradycardia. Naloxone was not associated with improved outcomes.

    The aim of this paper is to describe and evaluate the benefits of epidural anesthesia in major surgery neonatal. We have performed a matched case-control (2:1) study of patients undergoing neonatal major surgery (NMSs) who received intra-and postoperative epidural anesthesia (EA) and controls with conventional general anesthesia. The matching criteria were age, weight and baseline pathology. EA was administered by caudal puncture and epidural catheter placed with ultrasound support. Levobupivacaine was selected as anesthetic drug. The time to extubation, intestinal transit time, type of analgesia and complications were studied. This study is based on 11 cases (2 esophageal atresia, 2 diaphragmatic hernias, 1 necrotizing enterocolitis, 3 intestinal atresia, 2 anorectal malformation and 1 bladder exstrophy) and 22 controls. We observed statistically significant differences in time to extubation (95% CI OR 12 1.99 to 72.35; Chi2 p = 0.004, Mann U Whytney p = 0.013) and intestinal transit time (Mann Whitney U p analgesia. Therefore we believe that the intra-and postoperative EA helps improve postoperative management in neonates and should be preferred in centers where this technique is available.

    Full Text Available Introduction: Intra-articular (IA local anesthetics are often used for the management and prevention of pain after arthroscopic knee surgery. Clonidine prolongs the duration of local anesthetics. In this study, analgesic effect of intra-articular administration of levobupivacaine and clonidine was compared with ropivacaine and clonidine in knee joint arthroscopic surgery under spinal anesthesia. Method: 88 patients, aged between 15 to 55 years, ASA I and II undergoing knee arthroscopy under spinal anesthesia were assigned into two equal groups (n = 44 in a randomized double blind protocol. Patients in Group L received 10 ml of 0.50% levobupivacaine and 1 mcg/kg clonidine and Group R received 10 ml of 0.75% ropivacaine and 1 mcg/kg of clonidine through intra-articular route at the end of the procedure. In the post-operative period, pain intensity was assessed by VAS (Visual Analogue Scale Score recorded at 1 st , 5 th , 8 th , 12 th , 18 th post-operative hours. Duration of analgesia, total rescue analgesic dose in first 18 hours and any side effects were also recorded. Result: Group L experienced significantly longer duration of effective postoperative analgesia and lesser rescue analgesic compared to group R. Group R had higher mean VAS score at 5 th and 12 th post-operative hours (P < 0.05. No side effects were observed among the groups. Conclusion: Intra-articular administration of levobupivacaine and clonidine give better post-operative pain relief by increasing duration of analgesia, and decreasing need of rescue analgesic compared to intra-articular ropivacaine and clonidine.

    Full Text Available >Background: Dural puncture epidural (DPE is a method in which a dural hole is created prior to epidural injection. This study was planned to evaluate whether dural puncture improves onset and duration of labor analgesia when compared to conventional epidural technique.Methods and Materials: Sixty term primigravida parturients of ASA grade I and II were randomly assigned to two groups of 30 each (Group E for conventional epidural and Group DE for dural puncture epidural. In group E, epidural space was identified and 18-gauge multi-orifice catheter was threaded 5 cm into the epidural space. In group DE, dura was punctured using the combines spinal epidural (CSE spinal needle and epidural catheter threaded as in group E followed by 10 ml of injection of Ropivacaine (0.2% with 20 mcg of Fentanyl (2 mcg/ml in fractions of 2.5 ml. Later, Ropivacaine 10 ml was given as a top-up on patient request. Onset, visual analouge scale (VAS, sensory and motor block, haemodynamic variables, duration of analgesia of initial dose were noted along with mode of delivery and the neonatal outcome.Results: Six parturients in group DE achieved adequate analgesia in 5 minutes while none of those in group E (P 0.05.Conclusions: Both techniques of labor analgesia are efficacious; dural puncture epidural has the potential to fasten onset and improve quality of labor analgesia when compared with conventional epidural technique.

    Full Text Available BACKGROUND: Sciatica due to lumbar intervertebral disc herniation is one of the most common causes of radicular pain in an adult working population. This study aims at studying the effectiveness of conservative management of lumbar disc herniation as an alternative to surgical measures. METHODS: A prospective study of 100 patients with lumbar disc herniations who were treated conservatively were followed up at intervals of 1 month, 6 months and 1 year. Patients planned for conservative treatment were treated with pharmacological therapy, rest and physiotherapy. Those planned for epidural steroid injections were administered a single dose of steroid one level higher than the lesion in the epidural space. The collected data was analyzed by Chi square. RESULTS: Our results showed that in both genders, epidural steroid infiltration yielded better results than conservative treatment. Occupation had no discernible effect on the magnitude of disc herniation. People with sedentary lifestyle recovered better with epidural steroid infiltration as compared to the heavy physical labor group. Irrespective of disc bulge, protrusion or extrusion, the epidural steroid injection group showed significant improvement in symptoms as compared to conservative treatment. Smokers tended to show delay in the recovery as compared with the non-smoker group. The amount of disc herniation is not directly proportional to the outcome of treatment. CONCLUSIONS: Epidural steroid infiltration showed significant improvement in symptoms of lumbar intervertebral disc herniation thereby avoiding disc surgery. Conservative management for atleast 4 to 6 weeks can be recommended followed by epidural steroid in those patients without improvement. Cessation of smoking should be an integral part of the treatment.

    Pupillometry can be used to characterize autonomic drug effects. This study was conducted to determine the autonomic effects of 3,4-methylenedioxymethamphetamine (MDMA, ecstasy), administered alone and after pretreatment with reboxetine, duloxetine, clonidine, carvedilol, and doxazosin, on pupillary function. Infrared pupillometry was performed in five placebo-controlled randomized studies. Each study included 16 healthy subjects (eight men, eight women) who received placebo-MDMA (125 mg), placebo-placebo, pretreatment-placebo, or pretreatment-MDMA using a crossover design. MDMA produced mydriasis, prolonged the latency, reduced the response to light, and shortened the recovery time. The impaired reflex response was associated with subjective, cardiostimulant, and hyperthermic drug effects and returned to normal within 6 h after MDMA administration when plasma MDMA levels were still high. Mydriasis was associated with changes in plasma MDMA concentration over time and longer-lasting. Both reboxetine and duloxetine interacted with the effects of MDMA on pupillary function. Clonidine did not significantly reduce the mydriatic effects of MDMA, although it produced miosis when administered alone. Carvedilol and doxazosin did not alter the effects of MDMA on pupillary function. The MDMA-induced prolongation of the latency to and reduction of light-induced miosis indicate indirect central parasympathetic inhibition, and the faster recovery time reflects an increased sympathomimetic action. Both norepinephrine and serotonin mediate the effects of MDMA on pupillary function. Although mydriasis is lasting and mirrors the plasma concentration-time curve of MDMA, the impairment in the reaction to light is associated with the subjective and other autonomic effects of MDMA and exhibits acute tolerance.

    We report a case of paraspinal muscle infection shortly after epidural analgesia for labor pain in a nulliparous parturient who was subjected to emergent Cesarean section because of fetal distress. Epidural morphine was administered for 3 days for postoperative pain control. She began to have constant lower back pain on postpartum Day 4. Magnetic resonance image study revealed a broad area of subcutaneous edema with a continuum along the catheter trajectory deep to the paraspinal muscles. An injection-related bacterial infection was suspected; the patient was treated with intravenous antibiotics and was soon cured uncomplicatedly. Epidural analgesia is effective to control labor pain and, in general, it is safe. However, the sequelae of complicated infection may be underestimated. We herein report a case complicated by iatrogenic infection, discuss the causes, and give suggestions for prevention. Copyright © 2011. Published by Elsevier B.V.

    1998-01-01

    Extensive, diffuse, epidural spinal cord compression was visualized myelographically in two dogs presented for rapid development of nonambulatory tetraparesis and paraplegia, respectively. Purulent fluid containing bacterial organisms was aspirated percutaneously under fluoroscopic guidance from the epidural space of each dog. One dog responded poorly to aggressive medical therapy, which included installation of an epidural lavage and drainage system. Both dogs were euthanized due to the severe nature of their disorder and the poor prognosis. Spinal epidural empyema (i.e., abscess) is a rare condition in humans and has not been reported previously in the veterinary literature. Spinal epidural empyema should be considered as a differential diagnosis in dogs presenting with painful myelopathies, especially when accompanied by fever

    Full Text Available AIMS AND OBJECTIVES Magnesium has antinociceptive effects in animal and human models of pain. It is found that the addition of Magnesium sulphate to postoperative Epidural infusion of Fentanyl may decrease the need for Fentanyl. We undertook a study to compare the duration of postoperative analgesia after Epidural Fentanyl and Epidural Fentanyl plus Magnesium sulphate administered postoperatively, along with side effects. MATERIALS AND METHODS 50 patients undergoing elective lower limb and abdominal surgeries were randomized into one of the two groups with 25 patients in each group. Combined Spinal Epidural Anaesthesia was used for all patients. Spinal anaesthesia with 2.5 cc of 0.5% Hyperbaric Bupivacaine was given. When sensory blockade regressed to L1, patients were given either 50 µg of Fentanyl (diluted to 6cc with normal saline, Group F or 50 µg of Fentanyl plus 50 mg Magnesium sulphate (diluted to 6cc with normal saline, Group FM. Parameters like blood pressure, pulse rate, respiratory rate and oxygen saturation were monitored, and other side effects were noted. Data were analysed by using Student t test and Chi-square/ Fisher Exact tests. RESULTS There was significant difference in duration of analgesia between Group F (107 min and Group FM (143 min. Hemodynamic parameters were stable in both the groups with minimal side effects. CONCLUSION Co-administration of Magnesium sulphate with Fentanyl for postoperative Epidural analgesia results in prolongation of Fentanyl analgesia without significant side-effects.

    Full Text Available Background: To compare oral midazolam (0.5 mg/kg versus oral clonidine (4 μg/kg as a premedication in pediatric patients aged between 2-12 years with regard to sedation and anxiolysis. Methods: Sixty pediatric patients belonging to the American Society of Anesthesiologists class I and II between the age group of 2-12 years scheduled for elective surgery were randomly allocated to receive either oral midazolam (group I 30 min before induction or oral clonidine (group II 90 min before induction of anesthesia. The children were evaluated for levels of sedation and anxiety at the time of separation from the parents, venepuncture, and at the time of mask application for induction of anesthesia. Results: After premedication, the percentage of children who were sedated and calm increased in both the groups. The overall level of sedation was better in the children in the clonidine group, but children in the midazolam group had a greater degree of anxiolysis at times of venepuncture and mask application. In addition, midazolam did not cause significant changes in hemodynamics unlike clonidine where a significant fall in blood pressure was noted, after premedication, but preinduction. Conclusion: We conclude that under the conditions of the study, oral midazolam is superior to clonidine as an anxiolytic in pediatric population. Clonidine with its sedative action especially at the time of separation from parents along with its other perioperative benefits cannot be discounted.

To evaluate the effects of regional labour analgesia used at the Hospital for Gynecology and Obstetrics in Postojna, Slovenia, in the year 2002.Patients and methods. In this retrospective study we enrolled 294 parturients who delivered in the year 2002 in the Postojna Maternity Hospital: in group 1 there were 147 parturients in whom three different regional analgesic techniques (study group were used at labour; in group 2 there were 147 parturients in whom regional analgesia was not used (control group. In the first step the two groups were compared in terms of maternal demographic data, duration and outcome of labour and 1' and 5' Apgar scores. In the second step the three regional analgesic groups were compared in terms of the course and outcome of labour, fetal condition, side and adverse effects of regional analgesic techniques, and patient satisfaction with a particular analgesic technique.Results. Regional labour analgesia was used in 147 (14% of the 1048 women who delivered in 2002: epidural analgesia (EPI was performed in 51.0%, combined spinal-epidural (CSE in 42.2% and spinal analgesia (SA in 6.8% of cases. The women in the regional analgesia group were significantly older, more educated, more often nulliparous and accompanied by their partner at labour than the women in the control group. Further, the duration of labour was significantly longer, oxytocin more frequently administered than in the control group. In terms of labour outcome there were no differences in the Cesarean section rates and 1- and 5-min Apgar scores minutes, but and the vacuum extraction rate was significantly higher in the regional analgesia group. Among the three regional analgesia techniques used, there were no statistically significant differences observed in terms of labour duration and outcome, and Apgar scores. The patient satisfaction was greatest with CSE. Adverse side effects such as weak muscles, reduced motion abilities, itching, nausea

    We report the case of a 39-year-old woman with adolescent idiopathic scoliosis presenting with myelopathy secondary to a spinal epidural hemangioma. MRI showed an epidural soft tissue mass within the spinal canal between T5 and T9 with severe spinal cord compression. Symptoms had a temporal relationship to her pregnancy. Surgical removal of the epidural hemangioma rapidly relieved her symptoms and neurologic deficits. Follow-up examination 2 years later demonstrated normal motor and sensory function, without any neurologic sequelae or progression of deformity. (orig.)

    Spinal epidural hematomas are rare pathology, caused by trauma or spontaneous. In clinical examination acute spinal cord compression is observed. MRI designations appear entirely particular. In sagittal projection, biconvex mass in the dorsal, or sometimes ventral part of the spinal canal is clearly visible. This is well delineated by the thecal sac from the cord and cauda equina. MRI investigations in 3 patients revealed corresponding with spinal bone injuries and cord edema epidural hematomas. Differential diagnosis must contain subdural hematoma and epidural neoplasms or abscess. (author)

    Full Text Available Introduction & Objective: ECT is an inevitable therapy for many of psychiatric patients. During ECT severe hemodynamic changes occur which may cause dangerous cardiovascular complications especially in elderly patients with cardiac disease and may lead to arrhythmia,ischemia and myocardial infarction. The purpose of this study was to show the effect of clonidin and propranolol on the prevention of hemodynamic changes following the ECT.Materials & Methods: This study was a controlled double blind clinical trial which was carried out on 31 patients ASA I, II hospitalized in psychiatry ward of Hamadan Sina hospital who were in need of ECT. In order to increase the accuracy of the study the personal factors on the drug metabolism were omitted and the chosen patients were given ECT three times separately with the interval of 48 hours. Two hours before every ECT clonidin (0.2 mg, propranolol (40 mg and placebo (vitamin c were administered and after each ECT the hemodynamic parameters including systolic blood pressure, diastolic blood pressure, rate pressure product and ECG were measured at certain intervals and recorded on information forms and then analyzed by SPSS 9 soft ware. Results: The result of this study showed that the average changes of hemodynamic parameters in different times occurred in all groups significantly(p<0.001. Following ECT, arrhythmia in control group has been plentiful in comparison with the other two groups, and the changes were statistically meaningful (p=0.001.Conclusion: We concluded that the modifying hemodynamic changes and decrease of arrhythmia taking the drugs in comparison with placebo have been more effective and of the two drugs, propranolol has been more effective on the prevention of hemodynamic changes after ECT.

    Each year, more than 150,000 patients with rib fractures are admitted to US trauma centers; as many as 10% die. Effective pain control is critical to survival. One way to manage pain is thoracic epidural analgesia. If this treatment reduces mortality, more frequent use may be indicated. We analyzed the patient registry of a level II trauma center. All patients admitted with one or more rib fractures (N = 1,347) were considered. Patients who were not candidates for epidural analgesia (N = 382) were eliminated. Mortality was assessed with binary logistic regressions. Across the total population, mortality was 6.7%; incidence of pneumonia was 11.1%; mechanical ventilation was required in 23.8% of patients, for an average duration of 10.0 days; average stay in the hospital was 7.7 nights; and 49.7% of patients were admitted to the ICU for an average of 7.2 nights. Epidural analgesia was administered to 18.4% of patients. After matching samples for candidacy, patients who received epidurals were 3.7 years older, fractured 2.6 more ribs, had higher injury severity scores, and were more likely to present with bilateral fractures, flail segments, pulmonary contusions, hemothoraces, and pneumothoraces. Despite greater injury severity, mortality among these patients was lower (0.5%) than those who received alternative care (1.9%). Controlling for age, injury severity, and use of mechanical ventilation, epidural analgesia predicted a 97% reduction in mortality. Thoracic epidural analgesia associates with reduced mortality in rib fracture patients. Better care of this population is likely to be facilitated by more frequent reliance on this treatment. © 2016 American Academy of Pain Medicine. All rights reserved.

    To discover evidence for defining the registered nurse's (RN's) role in the management of epidural analgesia in the labor and delivery setting. The Labor Epidural Nurse Safety (LENS) study consisted of two parts. The first part was a 10-year retrospective review of the outcomes of 2,568 laboring women for whom epidural catheters had been placed and verified by an anesthesiologist or certified registered nurse anesthetist, then continuous epidural infusion initiated, and basal rate or patient-controlled epidural analgesia (PCEA) dose increased, if needed, within specified parameters by specially trained labor and delivery RNs. The second part compared the outcomes of the neonates born to the 2,568 women in the first part of the study with neonates born to mothers who received PCEA with a continuous infusion initiated and managed exclusively by anesthesiologists and/or certified registered nurse anesthetists at two control sites. Maternal outcomes were quantified by incidences of clinically significant hypotension and sentinel events, such as respiratory distress, cardio/respiratory distress, loss of consciousness, and seizures. Evidence of neonatal outcomes was collected by comparing Apgar scores. No sentinel events occurred, and there was no increase in maternal hypotensive events in the RN-managed group. There were no statistically significant differences in Apgar scores between the experimental and control groups. Specially trained RNs can safely initiate continuous infusions and increase the basal rate of epidural analgesia infusions or PCEA doses administered to laboring women, after insertion and confirmation of correct catheter placement by a qualified anesthesia provider, without adversely affecting maternal and fetal/neonatal outcomes.

    Although clonidine has been shown to prolong analgesia in central neuraxial blocks, its use in peripheral nerve blocks remains controversial. We performed a systematic review of the current literature to determine the benefit of adding clonidine to peripheral nerve blocks. A systematic, qualitative review of double-blind randomized controlled trials on the benefit of clonidine as an adjunct to peripheral nerve block was performed. Studies were identified by searching PubMed (www.ncbi.nlm.nih.gov/entrez) and EMBASE (www.embase.com) databases (July 1991 to October 2006) for terms related to clonidine as an adjunct to peripheral nerve blocks. Studies were classified as supportive if the use of clonidine demonstrated reduced pain and total analgesic consumption, or prolonged block duration versus negative if no difference was found. Twenty-seven studies were identified that met the inclusion criteria. Five studies included a systemic control group. The total number of patients reviewed was 1,385. The dose of clonidine varied from 30 to 300 mug. Overall 15 studies supported the use of clonidine as an adjunct to peripheral nerve blocks with 12 studies failing to show a benefit. Based on qualitative analysis, clonidine appeared to prolong analgesia when added to intermediate-acting local anesthetics for axillary and peribulbar blocks. Clonidine improves duration of analgesia and anesthesia when used as an adjunct to intermediate-acting local anesthetics for some peripheral nerve blocks. Side-effects appear to be limited at doses up to 150 mug. Evidence is lacking for the use of clonidine as an adjunct to local anesthetics for continuous catheter techniques. Further research is required to examine the peripheral analgesic mechanism of clonidine.

    Computed tomography permits reliable demonstration of the spinal canal and its contents. Measurements of the sagittal diameter of the bony canal do not take into consideration size, shape and state of intraspinal soft tissue structures, i.e. the thecal sac and its own contents, epidural fat and blood circulation pattern. Three particularly illustrative cases were selected in which obvious epidural venous engorgement was visualized in association with spinal stenosis. The authors think that epidural venous stasis occuring in segmental spinal stenosis is a CT sign of clinically significant narrowing of the neural canal. Accurate recognition of the type of lumbar stenosis together with epidural blood flow alterations permits a better understanding of the existing lesions. Thus, a more precise and specific surgical approach is possible. (orig.)

    A multicentered retrospective case series. To determine the incidence and circumstances surrounding the development of a symptomatic postoperative epidural hematoma in the cervical spine. Patients who underwent cervical spine surgery between January 1, 2005, and December 31, 2011, at 23 institutions were reviewed, and all patients who developed an epidural hematoma were identified. A total of 16 582 cervical spine surgeries were identified, and 15 patients developed a postoperative epidural hematoma, for a total incidence of 0.090%. Substantial variation between institutions was noted, with 11 sites reporting no epidural hematomas, and 1 site reporting an incidence of 0.76%. All patients initially presented with a neurologic deficit. Nine patients had complete resolution of the neurologic deficit after hematoma evacuation; however 2 of the 3 patients (66%) who had a delay in the diagnosis of the epidural hematoma had residual neurologic deficits compared to only 4 of the 12 patients (33%) who had no delay in the diagnosis or treatment ( P = .53). Additionally, the patients who experienced a postoperative epidural hematoma did not experience any significant improvement in health-related quality-of-life metrics as a result of the index procedure at final follow-up evaluation. This is the largest series to date to analyze the incidence of an epidural hematoma following cervical spine surgery, and this study suggest that an epidural hematoma occurs in approximately 1 out of 1000 cervical spine surgeries. Prompt diagnosis and treatment may improve the chance of making a complete neurologic recovery, but patients who develop this complication do not show improvements in the health-related quality-of-life measurements.

    According to our research, this is the first case described in the literature of spontaneous intracranial epidural hematoma secondary to the use of Xarelto®. Spontaneous intracranial epidural hematomas are rarely described in the literature. They are associated with infectious diseases of the skull, coagulation disorders, vascular malformations of the dura mater and metastasis to the skull. Long-term post-marketing monitoring and independent reports will probably detect the full spectrum of hemorrhagic complications of the use of rivaroxaban. (author)

  18. Clonidine versus Captopril for Severe Postpartum Hypertension: A Randomized Controlled Trial.

    Directory of Open Access Journals (Sweden)

    Carlos Noronha Neto C

    Full Text Available Changes during the puerperium are still unclear, particularly in women with hypertension. The choice of antihypertensives, both to control very high blood pressure episodes and to keep blood pressure stable, also requires further elucidation. Currently, there are no clear data to guide the decision for the choice of postpartum antihypertensives. Captopril plays an important role in the treatment of very high blood pressure episodes and may be used postpartum. Clonidine has been used as an alternative in pregnant or postpartum women with contraindications to captopril, with satisfactory effect. The objective of the present study was to evaluate the effectiveness and safety of clonidine compared to captopril for treating severe postpartum hypertension.A randomized, drug-controlled, triple-blind clinical trial evaluating postpartum women receiving captopril or clonidine. Inclusion criteria consisted of: women with hypertensive disorders of pregnancy systolic blood pressure (SBP ≥180 mmHg and/or diastolic blood pressure (DBP ≥110 mmHg], requiring magnesium sulfate. Exclusion criteria were: heart disease, smoking, illicit drug use, contraindications to captopril, clonidine or oral medication, and having used captopril/clonidine previously. The primary outcome was the frequency of very high blood pressure episodes while in the obstetric intensive care unit. A total of 90 postpartum women met the study inclusion criteria, with 45 randomized to each group. There were fewer very high blood pressure episodes during hospitalization (2.1 ± 2.1 vs. 3.5 ± 4.7, p = 0.08, greater percentage reduction in SBP (14.0% ± 8.6% vs. 10.8% ± 8.8%, p = 0.08 and fewer women requiring sodium nitroprusside (2.3% vs. 13.3%; RR: 0.17; 95%CI: 0.02-1.39; p = 0.06 in the clonidine group compared to the captopril group; however, these differences were not significant. The groups were similar regarding daily mean SBP or DBP; however, on the third postpartum day, mean SBP

    Effects of clonidine on the intraocular hydrodynamics demonstrated themselves as changes of 22 Na-clearance. This test is based on the principle of the intraocular penetration of contactly applied radioisotope and on monitoring the decreasing ocular radioactivity by means of external gamma detectors. The half-times of 22 Na-clearance were significantly prolonged after the local application of 100 μl of 0.5% clonidine (Isoglaucon Boehringer) as compared with the control group. The control animals displayed a half-time of 38.0+-2.7 in comparison with the treated animals measured at intervals of 30 to 90 min and 90 to 150 min after drug instillation, where half-times were significantly prolonged to 49.3+-4.3 and 63.4+-3.8, respectively. In other groups of rabbits 22 Na-clearance was measured on the contralateral eyes of after the intravenous injection of clonidine (25 μg per kg). In both cases the half-times did not significantly differ from the values found in controls. The observed changes of ocular hydrodynamics caused by clonidine probably reflect the inhibitory influence of this drug on aqueous humour production. Results of present investigations point to the decisive role of the local action of clonidine on the eye. (author)

    Full Text Available Withdrawal symptoms are a main reason of continuous use of opioid. This study compares the efficacy of augmentation of amantadine with clonidine in decreasing opioid withdrawal symptoms.This double-blind randomized clinical trial was carried out in the detoxification and rehabilitation inpatient ward at Razi Hospital, Tabriz, Iran during 2012. The patients were randomly assigned to receive clonidine or clonidine plus amantadine; and withdrawal symptoms were evaluated in the admission day and 24, 48, and 72 hours later. Data were analyzed using SPSS by the 2*2 repeated analyses of variances (ANOVA.From the total of 69 participants, 30 patients completed the trial in each group. The severity of symptoms, however, had an increasing trend in both groups. Analysis of variance of the symptom severity score (by The Clinical Opiate Withdrawal Scale revealed a significant group-time interaction, and the patients who were receiving amantadine experienced milder symptoms.Treatment of opioid withdrawal symptoms with amantadine and clonidine would result in a better outcome compared with clonidine alone.

    Breastfeeding is an important public health concern. High cumulative doses of epidural fentanyl administered for labor analgesia have been reported to be associated with early termination of breastfeeding. We tested the hypothesis that breastfeeding success is adversely influenced by the cumulative epidural fentanyl dose administered for labor analgesia. The study was a randomized, double-blind, controlled trial of parous women at greater than 38 weeks gestation who planned to breastfeed, had successfully breastfed a prior infant, and who received neuraxial labor analgesia. Participants were randomized to receive one of three epidural maintenance solutions for labor analgesia (bupivacaine 1 mg/ml, bupivacaine 0.8 mg/ml with fentanyl 1 μg/ml, or bupivacaine 0.625 mg/ml with fentanyl 2 μg/ml). The primary outcome was the proportion of women breastfeeding at 6 weeks postpartum. Maternal and umbilical venous blood fentanyl and bupivacaine concentration at delivery were measured. A total of 345 women were randomized and 305 had complete data for analysis. The frequency of breastfeeding at 6 weeks was 97, 98, and 94% in the groups receiving epidural fentanyl 0, 1, and 2 μg/ml, respectively (P = 0.34). The cumulative fentanyl dose (difference: 37 μg [95% CI of the difference, -58 to 79 μg], P = 0.28) and maternal and umbilical cord venous fentanyl and bupivacaine concentrations did not differ between women who discontinued breastfeeding and those who were still breastfeeding at 6 weeks postpartum. Labor epidural solutions containing fentanyl concentrations as high as 2 μg/ml do not appear to influence breastfeeding rates at 6 weeks postpartum.

    To determine whether preoperative epidural administration of morphine and detomidine would decrease postoperative lameness after bilateral stifle arthroscopy in horses. Prospective clinical controlled study. Eight adult horses that had bilateral arthroscopic procedures, including drilling of cartilage and subchondral bone within the femoropatellar joints. Horses were randomly separated into 2 groups. Preoperatively, 4 horses were administered a combination of epidural morphine (0.2 mg/kg) and detomidine (30 microg/kg), and 4 horses were administered an equivalent volume of epidural saline (0.9% NaCl) solution. Postoperative pain was assessed using 6 video recordings made at hourly intervals of each horse at a walk. Assessments began 1 hour after recovery from anesthesia. The recordings were scrambled out of sequence and evaluated by 3 observers, unaware of treatment groups, who scored lameness from 0 to 4. Lameness scores of the 2 groups of horses were compared using a Wilcoxon's rank sum test. Heart and respiratory rates were also measured at each hourly interval and compared between groups using a repeated-measures ANOVA; statistical significance was set at P detomidine significantly decreased lameness and heart rates after bilateral stifle arthroscopy. The greatest decrease was detected at hours 1 and 2 after recovery from anesthesia. We conclude that horses undergoing a painful arthroscopic procedure of the stifle joint benefit from the administration of preoperative epidural morphine and detomidine. Preoperative epidural administration of detomidine and morphine may be useful in decreasing postoperative pain after stifle arthroscopy as well as pain associated with other painful disorders involving the stifle joint, such as septic arthritis and trauma.

    Spinal epidural lipomatosis is a rare disorder that can manifest with progressive neurological deficits. It is characterized by abnormal accumulation of unencapsulated epidural fat commonly associated with the administration of exogenous steroids associated with a variety of systemic diseases, endocrinopathies, and Cushing syndrome (Fogel et al. Spine J 5:202–211, 2005). Occasionally, spinal epidural lipomatosis may occur in patients not exposed to steroids or in patients with endocrinopathies, primarily in obese individuals (Fogel et al. Spine J 5:202–211, 2005). However, spinal lumbar epidural lipomatosis resulting from local steroid injection has rarely been reported. We report the case of a 45-year-old diabetic man with claudication that was probably due to symptomatic lumbar spinal lipomatosis resulting from a single local epidural steroid injection.

    Epidural analgesia confers significant perioperative advantages to neonates undergoing surgical procedures but may be very technically challenging to place using a standard interlaminar loss-of-resistance to saline technique given the shallow depth of the epidural space. Thoracic epidural catheters placed via the caudal route may reduce the risk of direct neural injury from needle placement, but often pose higher risks of infection and/or improper positioning if placed without radiographic guidance. We present a detailed method of placing a fluoroscopically guided, tunneled transcaudal epidural catheter, which may reduce both of these risks. The accuracy and precision of this technique often provides adequate analgesia to allow for opioid-free epidural infusions as well as significant reductions in systemic opioids through the perioperative period. Opioid-free analgesia using a regional anesthetic technique allows for earlier extubation and reduced perioperative sedation, which may have a less deleterious neurocognitive effect on the developing brain of the neonate.

    Full Text Available BACKGROUND AND OBJECTIVES: S-(+-ketamine is an intravenous anaesthetic and sympathomimetic with properties of local anaesthetic. It has an effect of an analgetic and local anaesthetic when administered epidurally, but there are no data whether low doses of S-(+-ketamine have sympathomimetic effects. The aim of this study was to determine whether low doses of S-(+-ketamine, given epidurally together with local anaesthetic, have any effect on sympathetic nervous system, both systemic and below the level of anaesthetic block. METHODS: The study was conducted on two groups of patients to whom epidural anaesthesia was administered to. Local anaesthesia (0.5% bupivacaine was given to one group (control group while local anaesthesia and S-(+-ketamine were given to other group. Age, height, weight, systolic, diastolic and mean arterial blood pressure were measured. Non-competitive enzyme immunochemistry method (Cat Combi ELISA was used to determine the concentrations of catecholamines (adrenaline and noradrenaline. Immunoenzymometric determination with luminescent substrate on a machine called Vitros Eci was used to determine the concentration of cortisol. Pulse transit time was measured using photoplethysmography. Mann-Whitney U-test, Wilcoxon test and Friedman ANOVA were the statistical tests. Blood pressure, pulse, adrenaline, noradrenaline and cortisol concentrations were measured in order to estimate systemic sympathetic effects. RESULTS: 40 patients in the control group were given 0.5% bupivacaine and 40 patients in the test group were given 0.5% bupivacaine with S-(+-ketamine. Value p < 0.05 has been taken as a limit of statistical significance. CONCLUSIONS: Low dose of S-(+-ketamine administered epidurally had no sympathomimetic effects; it did not change blood pressure, pulse, serum hormones or pulse transit time. Low dose of S-(+-ketamine administered epidurally did not deepen sympathetic block. Adding 25 mg of S-(+-ketamine to 0

    The study evaluated the effect of local anesthesia with articaine in different combinations with epinephrine and clonidine (articaine (4%) + epinephrine (1:200 000), articaine (4%) + clonidine (1:100 000), articaine (4%) + epinephrine (1:200 000) + clonidine (1:100 000), articaine (4%) + epinephrine (1:400 000) + clonidine (1:100 000)), on a number of physiological parameters in pediatric dental practice that characterize cardiovascular system, patient's degree of adaptation to a stressful situation and efficacy of analgesia. It is shown that in terms of impact on the cardiovascular system and stress adaptation indicators anesthesia including combination of epinephrine (1: 200 000) and clonidine (1: 100 000) in the anesthetic solution is the safest. Furthermore, this method ensures the most appropriate analgesic effect.

    This prospective, randomized, double-blind study aimed to compare the efficacy of lidocaine with epinephrine versus lidocaine with clonidine for inferior alveolar nerve block (IANB) and hemodynamic stability (heart rate, systolic blood pressure, diastolic blood pressure and mean arterial pressure) in patients with irreversible pulpitis. One hundred patients with irreversible pulpitis in mandibular molar teeth randomly received 1.8 mL of 2% lidocaine with clonidine (15 μg mL -1 ) or 1.8 mL of 2% lidocaine with epinephrine (12.5 μg mL -1 ), using a conventional IANB technique. Endodontic access cavities were prepared 15 min after solution deposition, and all patients were required to have profound lip numbness. Success was defined as no or mild pain (visual analog scale recording) upon endodontic access cavity preparation or initial canal instrumentation. The hemodynamic parameters were measured before, during and 5, 10 and 30 min after administration. Finally, the collected data were subjected to independent t-test, chi-square and Fisher's exact test using spss software ver.20 at a significant level of 0.05. The success rates for IANB using lidocaine with epinephrine and lidocaine with clonidine solutions were 29% and 59%, respectively. The clonidine group exhibited a significantly higher success rate (P < 0.05). Five minutes after drug administration, systolic blood pressure and heart rate significantly increased in the lidocaine with epinephrine group and insignificantly decreased in lidocaine with clonidine group. For mandibular molars with irreversible pulpitis, addition of clonidine to lidocaine improved the success rate of IANB compared to a standard lidocaine/epinephrine solution. © 2016 International Endodontic Journal.

    2005-01-01

    Thirty-five patients (ASA II-III) aged 12 to 17 years, diagnosed as having osteogenic sarcoma and Ewing's sarcoma localizing in the femur and tibia, were examined. Surgery was performed as sectoral resection of the affected bone along with knee joint endoprosthesis. Surgical intervention was made under combined spinal and epidural anesthesia (CSEA) with sedation, by using the methods for exact dosing of propofol (6-4 mg/kg x h). During intervention, a child's respiration remains is kept spontaneous with oxygen insufflation through a nasal catheter. CSEA was performed in two-segmental fashion. The epidural space was first catheterized. After administration of a test dose, 0.5% marcaine spinal was injected into dermatomas below the subarachnoidal space, depending on body weight (3.0-4.0 ml). Sensory blockade developed following 3-5 min and lasted 90-120 min, thereafter a local anesthetic (bupivacaine) or its mixture plus promedole was epidurally administered. ??Anesthesia was effective in all cases, motor blockade. During surgery, there was a moderate arterial hypotension that did not require the use of vasopressors. The acid-alkali balance suggested the adequacy of spontaneous respiration. The only significant complication we observed was atony of the bladder that requires its catheterization till the following day. An epidural catheter makes it possible to effect adequate postoperative analgesia.

    Combined spinal epidural anesthesia (CSEA) has advantages over single injection epidural or subarachnoid blockades. The objective of this report was to present a case in which segmental subarachnoid block can be an effective technique for gastrointestinal surgery with spontaneous respiration. Patient with physical status ASA III, with diabetes mellitus type II, hypertension, and chronic obstructive pulmonary disease was scheduled for resection of a right colon tumor. Combined spinal epidural block was performed in the T5-T6 space and 8 mg of 0.5% isobaric bupivacaine with 50 microg of morphine were injected in the subarachnoid space. The epidural catheter (20G) was introduced four centimeters in the cephalad direction. Sedation was achieved with fractionated doses of 1 mg of midazolam (total of 6 mg). A bolus of 25 mg of 0.5% bupivacaine was administered through the catheter two hours after the subarachnoid block. Vasopressors and atropine were not used. This case provides evidence that segmental spinal block can be the anesthetic technique used in gastrointestinal surgeries with spontaneous respiration.

    Science.gov (United States)

    2013-01-01

    Background Transforaminal epidural steroid injections are known to reduce inflammation by inhibiting synthesis of various proinflammatory mediators and have been used increasingly. The anti-inflammatory properties of opioids are not as fully understood but apparently involve antagonism sensory neuron excitability and pro-inflammatory neuropeptide release. To date, no studies have addressed the efficacy of transforaminal epidural morphine in patients with radicular pain, and none have directly compared morphine with a tramadol for this indication. The aim of this study was to compare morphine and tramadol analgesia when administered via epidural injection to patients with lumbar radicular pain. Methods A total of 59 patients were randomly allocated to 1 of 2 treatment groups and followed for 3 months after procedure. Each patient was subjected to C-arm guided transforaminal epidural injection (TFEI) of an affected nerve root. As assigned, patients received either morphine sulfate (2.5 mg/2.5 ml) or tramadol (25 mg/0.5 ml) in combination with 0.2% ropivacaine (1 ml). Using numeric rating scale was subsequently rates at 2 weeks and 3 months following injection for comparison with baseline. Results Both groups had significantly lower mean pain scores at 2 weeks and at 3 months after treatment, but outcomes did not differ significantly between groups. Conclusions TFEI of an opioid plus local anesthetic proved effective in treating radicular pain. Although morphine surpassed tramadol in pain relief scores, the difference was not statistically significant. PMID:23862000

  14. Noninvasive Assessment of Gastric Emptying by Near-Infrared Fluorescence Reflectance Imaging in Mice: Pharmacological Validation with Tegaserod, Cisapride, and Clonidine

    2004-10-01

    Full Text Available Noninvasive near-infrared fluorescence reflectance imaging (FRI is an in vivo technique to assess physiological and molecular processes in the intact organism. Here we describe a method to assess gastric emptying in mice. TentaGel™ beads with covalently bound cyanine dye (Cy5.5 conjugates as fluorescent probe were administered by oral gavage. The amount of intragastric beads/label was derived from the fluorescence signal intensity measured in a region of interest corresponding to the mouse stomach. The FRI signal intensity decreased as a function of time reflecting gastric emptying. In control mice, the gastric half-emptying time was in agreement with literature data. Pharmacological modulation of gastric motility allowed the evaluation of the sensitivity of the FRI-based method. Gastric emptying was either stimulated or inhibited by treatment with the 5-HT4 receptor agonists tegaserod (Zelnorm® and cisapride or the α2-receptor agonist clonidine, respectively. Tegaserod and cisapride dose-dependently accelerated gastric emptying. In contrast, clonidine dose-dependently delayed gastric emptying. In conclusion, FRI using fluorescently labeled beads allows the reliable determination of gastric emptying as well as the assessment of pharmacological interventions. The technique thus offers the potential to characterize molecular targets and pathways involved in physiological regulation and pharmacological modulation of gastric emptying.

    Full Text Available Introduction. The use of epidural anaesthesia in delivery with the purpose to reduce pain and fear in a pregnant woman has the influence on the physiological status of the woman in childbirth and the course of delivery. From the epidural space of the pregnant woman, one part of free anaesthetic comes in the foetal circulation through the mother's circulation and placenta and connects with the foetal proteins. A lower value of albumins and serum proteins in the foetal circulation give bigger free fraction of anaesthetic which is accumulated in the foetal liver, brain and heart full of blood. Objective. The aim of the study was to examine the influence of epidural anaesthesia on the newborn. Methods. Retrospective study of 6,398 documents of newborns was performed in our Clinic of Gynaecology and Obstetrics 'Narodni front' during 2006. The first group was made of 455 newborns from deliveries with epidural anaesthesia and the second was the control group of 5,943 remaining newborns. In both groups we analysed the following: sex, week of gestation, weight, Apgar score, measure of care and resuscitation, perinatal morbidity and then the obtained results were compared. Results. Most of deliveries were vaginal without obstetric intervention (86.6%. The number of deliveries finished with vacuum extractor (4.6% was statistically significantly bigger in the group with epidural anaesthesia than in the control group. Most of the newborns in the first group were born on time (96.5% in 39.0±1.0 week of gestation and with foetal weight 3448±412 grammes. There was no statistical significance in Apgar score between both groups. Epidural anaesthesia does not increase the degree of the newborn's injury. Lower pH of blood was found in the newborns from deliveries with vacuum extractor or operated on (the Ceasarean section. Conclusion. Application of epidural anaesthesia decreases duration of delivery and has no adverse effects on the newborn and hypoxic

    Full Text Available Background: Epidural analgesia is the most effective analgesics used during childbirth but is not without its problems.In the Hospital San Juan de la Cruz of Ubeda from November 2011 we have detected 3 cases of newborn infants with signs of respiratory depression. Appeared in them: normal cardiotocographic records during childbirth, use of epidural associated with fentanyl, termination by vacuum and elevated temperature in one case.ObjectivesKnow if the neonatal adaptation to extrauterine life may be influenced by the use of epidural analgesia in childbirth. Review what role can have the rise in maternal temperature and the use of epidural fentanyl with the appearance of newborn respiratory distress.MethodsLiterature Review conducted in February of 2012 in Pubmed and the Cochrane Library, using the key words: childbirth, epidural analgesia, neonatal respiratory depression.ResultsOn the respiratory depression associated with fentanyl, a Cochrane review found indicating that newborns of mothers with an epidural, had a lower pH and were less need for administration of naloxone.On PubMed we find a review study that indicates that the respiratory depression caused by the administration of opioids via neuroaxial is rare, placing it below 1 per 1000, and a clinical case that concluded that doses of fentanyl exceeding 300 µg (approx. 5 µg/kg for 4 hours previous to childbirth, have a high risk of neonatal respiratory depression at birth.The same Cochrane review indicates that the women with epidural analgesia had increased risk of maternal fever of at least 38 ° C and a recent cohort study relates this increase in temperature with a greater likelihood of neonatal adverse events (from 37.5 ° C.ConclusionsThe studies found considered safe epidurals to the neonate and the mother, except when certain conditions are met. The literature and our clinical experience have been reports linking neonatal respiratory depression with increasing temperature (37

    Despite epidural analgesia increasingly being utilized in hospitals, very little research-based evidence is available about registered nurses' (RNs) and midwives' knowledge of this technique. To describe the current epidural knowledge levels of RNs and midwives in a multi-site setting. RNs and midwives at four, regional teaching facilities completed an epidural knowledge test. The instrument included demographic items and five knowledge subscales relating to epidural analgesia: spinal cord anatomy and physiology; epidural pharmacology; complications of epidural analgesia; assessment of sensory and motor blockade and the general management of patients with epidural analgesia. A total of 408 (99.7% response) RNs and midwives completed the test. Respondents demonstrated good knowledge of sensory and motor blockade assessment and the general management of epidural analgesia subscales with correct responses to 75 and 77% of the questions in these subscales, respectively. Fair knowledge relating to the spinal cord anatomy and physiology subscale was demonstrated with 69% of the questions answered correctly. The knowledge subscales relating to epidural pharmacology (57% correct responses) and the complications of epidural analgesia (56% correct responses) were problematic for the sample. The research results provide generalizable information about what RNs and midwives know about epidural analgesia. These results are an important guide in the development of new and existing dedicated epidural education programs. The results also provide some direction for further research into this important topic.

    Low back pain combined with radicular pain remains as one of the most challenging musculoskeletal problems for its therapeutic management. This malady results from nerve root impingement and/or inflammation that causes neurologic symptoms in the distribution of the affected nerve root(s) Conservative treatment, percutaneous spine interventions and surgery have all been used as treatment; and the particular treatment that's chosen depends on the severity of the clinical and neurologic presentation. In 1930, Evans reported that sciatica could treated by epidural injection. The use of epidural corticosteroid injections for the treatment of axial and radicular back pain was first reported in 1953. Epidural steroid injections are currently used by many medical professionals for the treatment of lumbosacral radiculopathy.

    Full Text Available Solitary epidural space metastasis of a malignant tumor is rare. We encountered a 79-year-old male patient with solitary metastatic epidural tumor who developed paraplegia and dysuria. The patient had undergone total gastrectomy for gastric cancer followed by chemotherapy 8 months priorly. The whole body was examined for suspected metastatic spinal tumor, but no metastases of the spine or important organs were observed, and a solitary mass was present in the thoracic spinal epidural space. The mass was excised for diagnosis and treatment and was histopathologically diagnosed as metastasis from gastric cancer. No solitary metastatic epidural tumor from gastric cancer has been reported in English. Among the Japanese, 3 cases have been reported, in which the outcome was poor in all cases and no definite diagnosis could be made before surgery in any case. Our patient developed concomitant pneumonia after surgery and died shortly after the surgery. When a patient has a past medical history of malignant tumor, the possibility of a solitary metastatic tumor in the epidural space should be considered.

    Full Text Available Introduction. Epidural lipomatosis is most frequently observed in patients on chronic steroid treatment. Only a few idiopathic epidural lipomatosis cases have been described. Material and Methods. 64-year-old male patient presented with low back pain and left leg pain. Later, the patient experienced neurogenic claudication and radicular pain in the left leg without urinary dysfunction. Plain radiography and magnetic resonance imaging demonstrated an abnormal fat tissue overgrowth in the epidural space with compression of the dural sac, degenerative disc disease at L4-L5 level, and instability at L5-S1. Endocrinopathic diseases and chronic steroid therapy were excluded. If conservative treatment failed, surgical treatment can be indicated. Results. After surgery, there was a gradual improvement in symptoms and signs, and six months later the patient returned to daily activities and was neurologically normal. Conclusion. In the absence of common causes of neurogenic claudication, epidural lipomatosis should be considered. The standard test for the diagnosis of epidural lipomatosis is magnetic resonance (MR. At first, conservative treatment must be considered; weight loss and the suspension of prior corticosteroid therapy are indicated. In the presence of neurological impairment, the operative treatment of wide surgical decompression must be performed soon after diagnosis.

    Gas production as a part of disc degeneration can occur but rarely causes nerve compression syndromes. The clinical features are similar to those of common sciatica. CT is very useful in the detection of epidural gas accumulation and nerve root compression. We report a case of symptomatic epidural gas accumulation originating from vacuum phenomenon in the intervertebral disc, causing lumbo-sacral radiculopathy. A 45-year-old woman suffered from sciatica for 9 months. The condition worsened in recent days. Computed tomography (CT) demonstrated intradiscal vacuum phenomenon, and accumulation of gas in the lumbar epidural space compressing the dural sac and S1 nerve root. After evacuation of the gas, her pain resolved without recurrence.

    Full Text Available Background. Traumatic delayed epidural hematoma (DEH can be defined as insignificant or not seen on the initial CT scan performed after a trauma but seen on the subsequent CT scan as a “massive” epidural bleeding. Case report. We presented two cases of traumatic DEH after mild head injury. Both patients were conscious and without neurological deficit on the admission. Initial CT scan did not reveal intracranial hematoma. Repeated CT scan, that was performed after neurological deterioration, revealed epidural hematoma in both cases. The patients were operated with a favorable surgical outcome. Conclusion. Traumatic DEH could occur in the patients with head injuries who were conscious on the admission with a normal initial CT scan finding. Early detection of DEH and an urgent surgical evacuation were essential for a good outcome.

    Full Text Available Sixty patients in the age group of 18-60 years of A.S.A. Grade I/II risk, scheduled for elective orthopaedic surgeries under general anaesthesia were studied for pre-medication with either oral clonidine or with combination of effects of diazepam & atropine. Patients in Group A (clonidine group received tablet clonidine 100 mcg (1 tablet if less than 50 kg in weight and 200 mcg if weighing more than 50 kg two hours before surgery. Patients in Group B (Diazepam-atropine group received one tablet of Diazepam (10 mg orally two hours before surgery and injection atropine-sulphate 0.01 mg/kg half an hour preoperatively by intramuscular route. In our study, the sedative and anti-sialogogue effects of clonidine were comparable to those of diazepam-atropine combination, which are commonly used premedicants. The anti-anxiety effect of clonidine was found to be better than that of diazepam-atropine combination. Clonidine also proved to be a better agent for the attenuation of pressor response to laryngoscopy and intubation. Thus, oral clonidine is a better premedicant compared to atropine-diazepam combination. Also, it is a more acceptable agent because of its oral route of administration.

    Opium is an addictive agent and one of the most common narcotics With great challenges of intraoperative hemodynamic instabilities. The current study aimed to assess the effects of clonidine on intraoperative blood loss in patients with and without opium addiction in femoral fracture surgeries. In a randomized clinical trial, 160 candidates for elective femoral fracture operations under general anesthesia were divided into four groups of 40 subjects: group 1 (placebo 1), subjects without addiction received placebo 90 minutes before the operation; group 2 (placebo 2), patients with opium addiction received placebo as group 1; group 3 (Clonidine 1), patients without addiction received clonidine 90 minutes before the operation and group 4 (Clonidine 2), patients with opium addiction received clonidine as premedication. Intraoperative blood loss in clonidine recipient groups, patients with and without addiction, was less than that of the placebos (both P values opium addiction. Premedication with clonidine to decrease intraoperative blood loss can be more effective in patients with opium addiction than the ones without addiction.

  9. Clonidine improved laboratory-measured decision-making performance in abstinent heroin addicts.

    Xiao-Li Zhang

    Full Text Available BACKGROUND: Impulsivity refers to a wide spectrum of actions characterized by quick and nonplanned reactions to external and internal stimuli, without taking into account the possible negative consequences for the individual or others, and decision-making is one of the biologically dissociated impulsive behaviors. Changes in impulsivity may be associated with norepinephrine. Various populations of drug addicts all performed impulsive decision making, which is a key risk factor in drug dependence and relapse. The present study investigated the effects of clonidine, which decreased norepinephrine release through presynaptic alpha-2 receptor activation, on the impaired decision-making performance in abstinent heroin addicts. METHODOLOGY/PRINCIPAL FINDINGS: Decision-making performance was assessed using the original version of Iowa Gambling Task (IGT. Both heroin addicts and normal controls were randomly assigned to three groups receiving clonidine, 0, 75 µg or 150 µg orally under double blind conditions. Psychiatric symptoms, including anxiety, depression and impulsivity, were rated on standardized scales. Heroin addicts reported higher scores on the Barratt Impulsiveness Scale and exhibited impaired decision-making on the IGT. A single high-dose of clonidine improved the decision-making performance in heroin addicts. CONCLUSIONS/SIGNIFICANCE: Our results suggest clonidine may have a potential therapeutic role in heroin addicts by improving the impaired impulsive decision-making. The current findings have important implications for behavioral and pharmacological interventions targeting decision-making in heroin addiction.

    1981-01-01

    A radioimmunoassay for clonidine was optimized by introducing, as a tracer ligand, an iodinized clonidine derivative specifically labeled with more than 500 Ci/mMol. The detection limit of clonidine was 10 pg/ml. The high assay specificity was demonstrated by a double isotope technique. The intraassay coefficient of variance (VK) was less than 4% for any concentration, the interassay VK did not exceed 8.3%. The assay reliability was increased when the plasma samples were diluted 1:5, prior to analysis, in normal human blood plasma, which was also used for the preparation of the calibration samples. In a comparative manner, this assay system was subjected to double-blind accuracy control tests, including all other reference methods so far described for clonidine analysis in blood plasma samples. The RIA technique presented here turned out to be the most sensitive and most reliable method, requiring, moreover, the smallest volumes of blood plasma (0.05 ml). This procedure was appropriate for routine tests, since one technician could perform 500 sample analyses a day. The advantages and disadvantages of each method are discussed

    Conclusion: Addition of clonidine 1 μg/kg to 20 ml bupivacaine 0.25% in TAP block bilaterally for cesarean section significantly increases the duration of postoperative analgesia, decreases postoperative analgesic requirement, and increases maternal comfort compared to 20 ml of bupivacaine 0.25% alone.

  12. GH response to intravenous clonidine challenge correlates with history of childhood trauma in personality disorder.

    Lee, Royce J; Fanning, Jennifer R; Coccaro, Emil F

    2016-05-01

    Childhood trauma is a risk factor for personality disorder. We have previously shown that childhood trauma is associated with increased central corticotrophin-releasing hormone concentration in adults with personality disorder. In the brain, the release of corticotrophin-releasing hormone can be stimulated by noradrenergic neuronal activity, raising the possibility that childhood trauma may affect the hypothalamic-pituitary adrenal (HPA) axis by altering brain noradrenergic function. In this study, we sought to test the hypothesis that childhood trauma is associated with blunted growth hormone response to the α-2 adrenergic autoreceptor agonist clonidine. All subjects provided written informed consent. Twenty personality disordered and twenty healthy controls (without personality disorder or Axis I psychopathology) underwent challenge with clonidine, while plasma Growth Hormone (GH) concentration was monitored by intravenous catheter. On a different study session, subjects completed the Childhood Trauma Questionnaire and underwent diagnostic interviews. Contrary to our a priori hypothesis, childhood trauma was associated with enhanced GH response to clonidine. This positive relationship was present in the group of 40 subjects and in the subgroup 20 personality disordered subjects, but was not detected in the healthy control subjects when analyzed separately. The presence of personality disorder was unrelated to the magnitude of GH response. Childhood trauma is positively correlated with GH response to clonidine challenge in adults with personality disorder. Enhanced rather that blunted GH response differentiates childhood trauma from previously identified negative predictors of GH response, such as anxiety or mood disorder.

  14. Clonidine is effective for the treatment of primary idiopathic hyperhidrosis and hot flushes: a case report.

    Albadrani, Ahmed

    2017-01-17

    While primary hyperhidrosis can be seen in men, accompanying hot flushes is rarely seen in men. Primary hyperhidrosis is thought to be related to overactivity of the sympathetic nervous system while hot flushes are believed to be related to altered peripheral vascular reactivity and a narrowed thermoregulatory zone. I report the case of a 29-year-old man of Arab origin who presented to a dermatology clinic with a complaint of generalized sweating, with heavier involvement of his inguinal region, axilla, and lower back. His complaint was associated with a transient hot sensation and erythema over the affected areas. He did not respond to topical antiperspirants containing aluminum chloride, topical aluminum chloride, or to botulinum toxin A injected in both inguinal areas. He was then referred to an endocrinology clinic to rule out secondary causes of hyperhidrosis and hot flushes; a primary diagnosis was confirmed. He did not respond to oral glycopyrrolate and additionally was complaining of its anticholinergic side effects. The glycopyrrolate was then replaced with oral clonidine 0.15 mg twice a day. Clonidine was well tolerated without remarkable side effects and he quickly started to feel marked improvement which was maintained for 2 years. I report an atypical presentation of primary hyperhidrosis and hot flushes that was effectively controlled by clonidine without remarkable side effects. Further research on a large number of patients may be required before recommending clonidine in similar conditions.

  15. Clonidine improves attentional and memory components of delayed response performance in a model of early Parkinsonism.

    Cognitive deficits, including attention and working memory deficits, are often described in Parkinson's disease (PD) patients even during the early stages of the disease. However, cognitive deficits associated with PD have proven difficult to treat and often do not respond well to the dopaminergic therapies used to treat the motor symptoms of the disease. Chronic administration of low doses of the neurotoxin 1-methy,4-phenyl,1,2,3,6-tetrahydropyridine (MPTP) can induce cognitive dysfunction in non-human primates, including impaired performance on a variable delayed response (VDR) task with attentional and memory components. Since alpha-2 adrenergic receptor agonists have been suggested to improve attention and working memory in a variety of conditions, the present study assessed the extent to which the alpha-2 noradrenergic agonist clonidine might influence VDR performance in early Parkinsonian non-human primates. Clonidine (0.02-0.10 mg/kg) improved performance on both attentional and memory components of the task, performed in a modified Wisconsin General Test Apparatus, in a dose-dependent manner and the cognition enhancing effects of clonidine were blocked by co-administration of the alpha-2 noradrenergic antagonist idazoxan (0.10 mg/kg). These data suggest that clonidine or drugs of this class, perhaps with greater receptor subtype selectivity and low sedation liability, might be effective therapeutics for cognitive dysfunction associated with PD.

    Full Text Available This randomised, placebo-controlled, double-blind study was designed to assess the effect of intravenous clonidine and magnesium sulphate on intraoperative haemodynamics, anaesthetic consumption and postoperative recovery. Seventy five patients undergoing elective upper limb orthopaedic surgery were randomised into three groups. Group C received clonidine 3 μg/kg as a bolus before induction and 1μg/kg/hour by infusion intraopertively. Group M received magnesium sulphate 30 mg/kg as a bolus before induction and 10 mg/kg/hour by infusion. Group P received same volume of isotonic saline. Anaesthesia was induced and maintained with fentanyl citrate and propofol. Muscular relaxation was achieved by vecuronium bromide. Induction time, recovery time and consumption of propofol as well as fentanyl citrate were recorded. Induction of anaesthesia was rapid with both clonidine and magnesium sulphate. Time of bispectral index (BIS to reach 60 was significantly lower in Group C and Group M (P < 0.0001. Requirements of propofol and fentanyl were significantly less in Group C and Group M (P < 0.001. Postoperative recovery was slower in Group M compared with other two groups (P < 0.001. Perioperative use of both clonidine and magnesium sulphate significantly reduced the consumption of propofol and fentanyl citrate. Magnesium sulphate caused a delayed recovery.

    Full Text Available Objective: Evaluate the ability of clonidine to reduce pulmonary arterial pressure in patients with pulmonary hypertension undergoing heart surgery, either by reducing the pressure values from the direct measurement of pulmonary arterial pressure or by reducing or eliminating the need for intraoperative dobutamine and nitroprusside. Method: Randomized, double-blind, placebo-controlled, comparative study conducted in 30 patients with pulmonary arterial hypertension type 2 undergoing cardiac surgery. Mean pulmonary arterial pressure and dosage of dobutamine and sodium nitroprusside were assessed four times: before intravenous administration of clonidine (2 μg/kg or placebo (T0, 30 min after tested treatment and before cardiopulmonary bypass (T1, immediately after CPB (T2, 10 min after protamine injection (T3. Results: There were no significant differences regarding mean pulmonary arterial pressure at any time of evaluation. There was no significant difference between groups regarding other variables, such as mean systemic arterial pressure, heart rate, total dose of dobutamine, total dose of sodium nitroprusside, and need for fentanyl. Conclusion: Data analysis from patients included in this study allows us to conclude that intravenous clonidine (2 μg/kg was not able to reduce the mean pulmonary arterial pressure in patients with pulmonary hypertension in group 2 (pulmonary venous hypertension, undergoing heart surgery, or reduce or eliminate the need for intraoperative administration of dobutamine and sodium nitroprusside.

    Pituitary masses are common lesions accounting for about 15-20% of all brain tumours. Oozing blood is an annoyance in microscopic sublabial trans-sphenoidal approach for these masses. There have been many ways of reducing the ooze, having their own pros and cons. To find out the efficacy and safety of clonidine in reducing blood loss in pituitary adenoma surgery through a randomized masked trial. It was a prospective randomized controlled trial done. Total 50 patients of pituitary adenomas were randomized into two groups. Group A (25 patients) was given 200 μg clonidine orally, while Group B (25 patients) was given placebo. Surgeon, anaesthesiologist and patient were blinded for the trial. Sublabial trans-septal trans-sphenoidal approach to sella and excision of mass was performed in each patient. Patients were studied for pre-, intra- and post-operative blood pressure and heart rate, pre- and post-operative imaging findings, intra-operative blood loss, bleeding grading by surgeon, surgeon's satisfaction about condition of specific part and quality of surgical field, operative time and extent of resection. Blood loss during the surgery, operative time and bleeding grading by the surgeon were found significantly less in the clonidine group, while quality of surgical field, condition of the specific part and extent of resection were found significantly better in the clonidine group (p value trans-sphenoidal microscopic pituitary adenoma surgeries.

    Full Text Available BACKGROUND: Epidural anaesthesia is suitable as a sole agent for lower abdominal surgery and surgery on lower limbs. It has some definite advantages over spinal anaesthesia like avoidance of post spinal headache, minimal chances of meningitis, and minimal chances of nausea and vomiting in postoperative period. But administration of conventional dosage of local epidural anaesthetics (15ml and above for surgical anaesthesia frequently results in multiple hemodynamic changes, including decreases in chronotropism, inotro pism, dromotropism, systemic vascular resistance, cardiac output, and myocardial oxygen consumption. The segmental epidural block denotes the use of a small volume enough to block only the segments involved in the field of surgery. AIM: To study the effect iveness of segmental epidural anaesthesia for inguinal hernia repair. DESIGN: R andomized control study. METHODS: 100 pts belonging to ASA PS I & II posted for inguinal hernia repair given 5ml of 0.5% bupivacaine through epidural route at L1 - L2 level and a fter conforming the adequacy and level of analgesia, the surgery was commenced. If the patient complained of pain during needle prick, then injected local anaesthetic (0.5% Bupivacaine with an incremental dosage of 1ml at a time, till the complete onset o f analgesia Pulse Rate and Blood Pressure were recorded at an interval of 1 minute for first 5 minutes and then every 5 minutes till the end of the surgery. Oxygen saturation and ECG monitoring was done continuously. Onset of analgesia, level of analgesia ( P re & post operatively, duration of analgesia, total dosage of local anaesthetic used were recorded. Complications like bradycardia, hypotension, respiratory depression, shivering, nausea and vomiting, sweating and inadvertent dural puncture were recorde d. RESULTS: 53% of patients had excellent quality of analgesia and relaxation. 34% patients had good quality analgesia and relaxation, mild discomfort while handling sac

    Nocardia species exist in the environment as a saprophyte; it is found worldwide in soil and decaying plant matter. They often infect patients with underlying immune compromise, pulmonary disease or history of trauma or surgery. The diagnosis of nocardiosis can be easily missed as it mimics many other granulomatous and neoplastic disease. We report a 69-year-old man who presented with chronic back pain and paraparesis. He was found to have Nocardial brasiliensis vertebral osteomyelitis and epidural abscess. Laminectomy and epidural wash out was performed but with no neurological recovery. This is the second reported case of N brasiliensis vertebral osteomyelitis in the literature.

    Full Text Available Spinal epidural abscess (SEA is a rare disease which is often rapidly progressive. Delayed diagnosis of SEA may lead to serious complications and the clinical findings of SEA are generally nonspecific. Paraspinal abscess should be considered in the presence of local low back tenderness, redness, and pain with fever, particularly in children. In case of delayed diagnosis and treatment, SEA may spread to the epidural space and may cause neurological deficits. Magnetic resonance imaging (MRI remains the method of choice in the diagnosis of SEA. Treatment of SEA often consists of both medical and surgical therapy including drainage with percutaneous entry, corpectomy, and instrumentation.

    We have compared fetal heart rate patterns, Apgar scores and umbilical cord gas values following initiation of labour analgesia using either combined spinal-epidural or epidural. One hundred and fifteen healthy women requesting neuraxial analgesia in the first stage of labour were randomly assigned to receive either combined spinal-epidural (n = 62) or epidural analgesia (n = 53). Fetal heart rate traces, recorded for 30 min before and 60 min after neuraxial block, were categorised as normal, suspicious or pathological according to national guidelines. Sixty-one fetal heart rate tracings were analysed in the combined spinal-epidural group and 52 in the epidural group. No significant differences were found in fetal heart rate patterns, Apgar scores or umbilical artery and vein acid-base status between groups. However, in both combined spinal-epidural and epidural groups, there was a significant increase in the incidence of abnormal fetal heart rate patterns following neuraxial analgesia (p analgesia in the combined spinal-epidural group and zero before compared with 11 after in the epidural group. These changes comprised increased decelerations (p = 0.0045) (combined spinal-epidural group nine before and 14 after analgesia, epidural group four before and 16 after), increased late decelerations (p analgesia, epidural group zero before and eight after), and a reduction in acceleration rate (p = 0.034) (combined spinal-epidural group mean (SD) 12.2 (6.7) h(-1) before and 9.9 (6.1) h(-1) after analgesia, epidural group 11.0 (7.3) h(-1) before and 8.4 (5.9) h(-1) after). These fetal heart rate changes did not affect neonatal outcome in this healthy population. © 2014 The Association of Anaesthetists of Great Britain and Ireland.

    Full Text Available In human cirrhosis, adrenergic hyperfunction causes proximal tubular fluid retention and contributes to diuretic-resistant ascites, and clonidine, a sympatholytic drug, improves natriuresis in difficult-to-treat ascites.To compare clonidine (aspecific α2-adrenoceptor agonist to SSP-002021R (prodrug of guanfacine, specific α2A-receptor agonist, both associated with diuretics, in experimental cirrhotic ascites.Six groups of 12 rats were studied: controls (G1; controls receiving furosemide and potassium canrenoate (G2; rats with ascitic cirrhosis due to 14-week CCl4 treatment (G3; cirrhotic rats treated (over the 11th-14th CCl4 weeks with furosemide and canrenoate (G4, furosemide, canrenoate and clonidine (G5, or diuretics and SSP002021R (G6. Three rats of each group had their hormonal status and renal function assessed at the end of 11th, 12th, 13th, and 14th weeks of respective treatments.Cirrhotic rats in G3 and G4 gained weight over the 12th-14th CCl4 weeks. In G4, brief increase in sodium excretion over the 11th-12th weeks preceded worsening of inulin clearance and natriuresis (diuretic resistance. In comparison with G4, the addition of clonidine (G5 or guanfacine (G6 to diuretics improved, respectively, sodium excretion over the 11th-12th CCl4 weeks, or GFR and electrolytes excretion over the 13th-14th CCl4 weeks. Natriuretic responses in G5 and G6 were accompanied by reduced catecholamine serum levels.α2A-receptor agonists restore glomerular filtration rate and natriuresis, and delay diuretic-resistant ascites in experimental advanced cirrhosis. Clonidine ameliorates diuretic-dependent natriuresis just for a short time.

    Both clonidine and ketamine have been found to prolong the action of local anesthetics through a peripheral mechanism. Our study compares the efficacy of a low dose of clonidine or ketamine separately added to intravenous regional anesthesia (IVRA) with lidocaine to prevent tourniquet pain. We conducted a prospective randomized double-blinded study in 45 patients undergoing hand or forearm surgery, with anticipated duration exceeding 1 hour under IVRA. Proximal cuff inflation of a double tourniquet was followed by administration of 40 mL of lidocaine 0.5% and either saline, 1 microg/kg clonidine, or 0.1 mg/kg ketamine. When anesthesia was established, the inflation of the proximal and distal cuff was interchanged. Thereafter, tourniquet pain was rated on a visual analog scale (VAS) every 10 minutes. Intraoperatively, boluses of 25 microg fentanyl were provided for tourniquet pain treatment when required, and total fentanyl consumption was recorded. Patients receiving plain lidocaine persistently reported the highest pain scores among groups (P <.001) 20 minutes after distal cuff inflation. Differences between the groups with additional treatment were noted 50 minutes after distal cuff inflation and until the end of the observation, with significantly lower VAS ratings (P <.001 to P <.01) in ketamine-treated patients. Total fentanyl consumption was significantly decreased by ketamine (70.00 +/- 25.35 microg) or clonidine (136.67 +/- 39.94 microg) compared with the plain lidocaine group (215.33 +/- 52.33 microg) (P <.001 between all groups). The addition of clonidine 1 microg/kg or ketamine 0.1 mg/kg to lidocaine for IVRA delays the onset of unbearable tourniquet pain and decreases analgesic consumption for tourniquet pain relief, although ketamine has a more potent effect.

    Acute low back pain, radiculopathy, and associated disabilities have a prevalence of 2% in the United States, which represents a significant health problem and a major cause of workplace absence. The condition primarily affects 25- to 45-year-old men and women. Epidural steroid injections (ESIs) are commonly administered to relieve this pain and improve mobility without surgery. This case report presents issues related to the treatment of an epidural hematoma in an 87-year-old man receiving long-term anticoagulant therapy. It reviews the risks, benefits, side effects, complications, and contraindications to ESI and the American Society of Regional Anesthesia consensus recommendations for the performance of neuraxial procedures in patients receiving anticoagulant therapy. It is imperative that any provider who performs ESIs know the risks, benefits, complications, and contraindications for this procedure. Practitioners must also be able to recognize and manage or appropriately refer patients having immediate or delayed complications related to the placement of an ESI.

    Full Text Available Background and Aims: Opioids as epidural adjunct to local anesthetics (LA have been in use since long and α-2 agonists are being increasingly used for similar purpose. The present study aims at comparing the hemodynamic, sedative, and analgesia potentiating effects of epidurally administered fentanyl and dexmedetomidine when combined with ropivacaine. Methods: A total of one hundred patients of both gender aged 21-56 years, American Society of Anaesthesiologist (ASA physical status I and II who underwent lower limb orthopedic surgery were enrolled into the present study. Patients were randomly divided into two groups: Ropivacaine + Dexmedetomidine (RD and Ropivacaine + Fentanyl (RF, comprising 50 patie nts each. Inj. Ropivacaine, 15 ml of 0.75%, was administered epidurally in both the groups with addition of 1 μg/kg of dexmedetomidine in RD group and 1 μg/kg of fentanyl in RF group. Besides cardio-respiratory parameters and sedation scores, various block characteristics were also observed which included time to onset of analgesia at T10, maximum sensory analgesic level, time to complete motor blockade, time to two segmental dermatomal regressions, and time to first rescue analgesic. At the end of study, data was compiled systematically and analyzed using ANOVA with post-hoc significance, Chi-square test and Fisher′s exact test. Value of P<0.05 is considered significant and P<0.001 as highly significant. Results: The demographic profile of patients was comparable in both the groups. Onset of sensory analgesia at T10 (7.12±2.44 vs 9.14±2.94 and establishment of complete motor blockade (18.16±4.52 vs 22.98±4.78 was significantly earlier in the RD group. Postoperative analgesia was prolonged significantly in the RD group (366.62±24.42 and consequently low dose consumption of local anaesthetic LA (76.82±14.28 vs 104.35±18.96 during epidural top-ups postoperatively.

    Full Text Available Background. Dexmedetomidine combined with local anesthetics can decrease the concentration of epidural ropivacaine. However, the optimal dose of epidural dexmedetomidine combined with ropivacaine for labor analgesia is still uncertain. This study investigated the effect of adding different dose of epidural dexmedetomidine to ropivacaine during epidural labor analgesia. Methods. One hundred women were randomly assigned to one of the four groups (Groups A, B, C, and D received 0.25, 0.5, 0.75, and 1 μg/ml of dexmedetomidine plus 0.1% ropivacaine, resp.. The onset of epidural anesthesia and stages of labor were studied, and pain was assessed using a visual analogue scale (VAS. Hemodynamic parameters and fetal heart rate were monitored. Apgar scores and umbilical artery pH were recorded. The side effects, if any, were recorded also. Results. The addition of 0.25, 0.5, and 0.75 μg/ml of dexmedetomidine to 0.1% ropivacaine provided safe and effective analgesia, but 1 μg/ml of dexmedetomidine resulted in increasing incidence of motor block. The hemodynamic parameters were similar between groups (P>0.05. Side effects in Group D were significantly higher than those in the other three groups (P<0.05. Conclusions. When dexmedetomidine is combined with 0.1% ropivacaine, the optimal concentration of dexmedetomidine is 0.5 μg/ml for epidural labor analgesia (this trial is registered with ChiCTR-OPC-16008548.

    Full Text Available Background: Despite advances in the knowledge of pathophysiology of pain and its management, patients continue to suffer from pain in many terminal stage cancer. Tramadol hydrochloride is a weak opioid with analgesic properties, and can be tried for cancer pain management. Objectives: This study was performed to find out the efficacy of the analgesic property of Tramadol through epidural route in cancer patients as an combination with low dose(.125% Bupivacaine and to compare with Fentanyl, a μ opioid agonist. Methods: 50 Cancer patients with or without previous pain management were randomly allocated to one of the two study regime- Group-A (tramadol 50 mg and Group-B (Fentanyl 50 mgm in combination with .125% Bupivacaine. Drugs were administered epidurally 6 hourly, 8 hourly and 12 hourly respectively for the 1st, 2nd and 3rd day. Low dose bupivacaine was added to both groups to enhance quality. Pain scores, blood pressure, respiratory rate, heart rate, side effects and patients' satisfaction score was recorded 6 hourly for 72 hrs. The data yielded from this study were compiled and analyzed by unpaired and paired ‘t' test with 95% confidence limit. A value of P< 0.05 was considered to be significant. ÷ square test was done for some of the data. Results: Pain scores were significantly decreased in both the groups but were not significantly different. The incidence of side effects including nausea and vomiting was found in both the groups and was not significantly different between the two groups. Conclusion: The use of epidural Tramadol in selected cancer pain patients (especially pain in lower abdomen and lower back may be very useful and is comparable to opioid in certain situations.

    To describe the MRI findings in ten patients of spinal epidural angiolipoma for differentiated diagnosis presurgery. Ten surgically proved cases of spinal epidural angiolipomas were retrospectively reviewed, and the lesion was classified according to the MR findings. Ten tumors were located in the superior (n = 4), middle (n = 2), or inferior (n = 4) thoracic level. The mass, with the spindle shape, was located in the posterior epidural space and extended parallel to the long axis of the spine. All lesions contained a fat and vascular element. The vascular content, correlating with the presence of hypointense regions on T1-weighted imaging (T1WI) and hyperintense signals on T2-weighted imaging, had marked enhancement. However, there were no flow void signs on MR images. All tumors were divided into two types based on the MR features. In type 1 (n = 3), the mass was predominantly composed of lipomatous tissue (> 50%) and contained only a few small angiomatous regions, which had a trabeculated or mottled appear. In type 2 (n = 7), the mass, however, was predominantly composed of vascular components (> 50%), which presented as large foci in the center of the mass. Most spinal epidural angiolipomas exhibit hyperintensity on T1WI while the hypointense region on the noncontrast T1WI indicates to be vascular, which manifests an obvious enhancement with gadolinium administration.

    The objective of our study is to evaluate the correlation between epidural analgesia during labor, start of breastfeeding and type of maternal-neonatal care.Two different assistance models were considered: Partial and Full Rooming-in.In this cohort study, 2480 healthy infants were enrolled, 1519 in the Partial Rooming-in group and 1321 in the Full Rooming-in group; 1223 were born to women subjected to epidural analgesia in labor.In case of Partial Rooming-in the rate of exclusive or prevailing breastfeeding is significant more frequent in newborns born to mothers who didn't receive analgesia. Instead, in case of Full Rooming-in the rate of exclusive or prevailing breastfeeding is almost the same and there's no correlation between the use or not of epidural analgesia.The good start of lactation and the success of breastfeeding seems to be guaranteed by the type of care offered to the couple mother-infant, that reverses any possible adverse effects of the use of epidural analgesia in labor.

    BACKGROUND: The role of noradrenergic system in the control of nociception is documented in some vertebrate animals. However, there are no data showing the role of this system on nociception in the marsh terrapins. METHODOLOGY: In this study, the antinociceptive action of intrathecal administration...... of the α 2-adrenoreceptor agonist clonidine and α 2-adrenoreceptor antagonist yohimbine was evaluated in the African marsh terrapin using the formalin test. The interaction of clonidine and yohimbine was also evaluated. RESULTS: Intrathecal administration of clonidine (37.5 or 65 μg/kg) caused...... a significant reduction in the mean time spent in pain-related behavior. Yohimbine, at a dose of 25 μg/kg, significantly blocked the effect of clonidine (65 μg/kg). However, administration of yohimbine (40 or 53 μg/kg) caused a significant reduction in the mean time spent in pain-related behavior. Intrathecal...

    Full Text Available Background and objectives: S-(+-ketamine is an intravenous anaesthetic and sympathomimetic with properties of local anaesthetic. It has an effect of an analgetic and local anaesthetic when administered epidurally, but there are no data whether low doses of S-(+-ketamine have sympathomimetic effects. The aim of this study was to determine whether low doses of S-(+-ketamine, given epidurally together with local anaesthetic, have any effect on sympathetic nervous system, both systemic and below the level of anaesthetic block. Methods: The study was conducted on two groups of patients to whom epidural anaesthesia was administered to. Local anaesthesia (0.5% bupivacaine was given to one group (control group while local anaesthesia and S-(+-ketamine were given to other group. Age, height, weight, systolic, diastolic and mean arterial blood pressure were measured. Non-competitive enzyme immunochemistry method (Cat Combi ELISA was used to determine the concentrations of catecholamines (adrenaline and noradrenaline. Immunoenzymometric determination with luminescent substrate on a machine called Vitros Eci was used to determine the concentration of cortisol. Pulse transit time was measured using photoplethysmography. Mann–Whitney U-test, Wilcoxon test and Friedman ANOVA were the statistical tests. Blood pressure, pulse, adrenaline, noradrenaline and cortisol concentrations were measured in order to estimate systemic sympathetic effects. Results: 40 patients in the control group were given 0.5% bupivacaine and 40 patients in the test group were given 0.5% bupivacaine with S-(+-ketamine. Value p < 0.05 has been taken as a limit of statistical significance. Conclusions: Low dose of S-(+-ketamine administered epidurally had no sympathomimetic effects; it did not change blood pressure, pulse, serum hormones or pulse transit time. Low dose of S-(+-ketamine administered epidurally did not deepen sympathetic block. Adding 25 mg of S-(+-ketamine to 0

    The evolution of imaging techniques, along with highly effective radiation options has changed the way metastatic epidural tumors are treated. While high-grade epidural spinal cord compression (ESCC) frequently serves as an indication for surgical decompression, no consensus exists in the literature about the precise definition of this term. The advancement of the treatment paradigms in patients with metastatic tumors for the spine requires a clear grading scheme of ESCC. The degree of ESCC often serves as a major determinant in the decision to operate or irradiate. The purpose of this study was to determine the reliability and validity of a 6-point, MR imaging-based grading system for ESCC. To determine the reliability of the grading scale, a survey was distributed to 7 spine surgeons who participate in the Spine Oncology Study Group. The MR images of 25 cervical or thoracic spinal tumors were distributed consisting of 1 sagittal image and 3 axial images at the identical level including T1-weighted, T2-weighted, and Gd-enhanced T1-weighted images. The survey was administered 3 times at 2-week intervals. The inter- and intrarater reliability was assessed. The inter- and intrarater reliability ranged from good to excellent when surgeons were asked to rate the degree of spinal cord compression using T2-weighted axial images. The T2-weighted images were superior indicators of ESCC compared with T1-weighted images with and without Gd. The ESCC scale provides a valid and reliable instrument that may be used to describe the degree of ESCC based on T2-weighted MR images. This scale accounts for recent advances in the treatment of spinal metastases and may be used to provide an ESCC classification scheme for multicenter clinical trial and outcome studies.

    To compare analgesic efficacy of preoperative versus postoperative administration of carprofen and to determine, if preincisional mepivacaine epidural anesthesia improves postoperative analgesia in dogs treated with carprofen. Blind, randomized clinical study. Dogs with femoral (n=18) or pelvic (27) fractures. Dogs were grouped by restricted randomization into 4 groups: group 1 = carprofen (4 mg/kg subcutaneously) immediately before induction of anesthesia, no epidural anesthesia; group 2 = carprofen immediately after extubation, no epidural anesthesia; group 3 = carprofen immediately before induction, mepivacaine epidural block 15 minutes before surgical incision; and group 4 = mepivacaine epidural block 15 minutes before surgical incision, carprofen after extubation. All dogs were administered carprofen (4 mg/kg, subcutaneously, once daily) for 4 days after surgery. Physiologic variables, nociceptive threshold, lameness score, pain, and sedation (numerical rating scale [NRS], visual analog scale [VAS]), plasma glucose and cortisol concentration, renal function, and hemostatic variables were measured preoperatively and at various times after surgery. Dogs with VAS pain scores >30 were administered rescue analgesia. Group 3 and 4 dogs had significantly lower pain scores and amount of rescue analgesia compared with groups 1 and 2. VAS and NRS pain scores were not significantly different among groups 1 and 2 or among groups 3 and 4. There was no treatment effect on renal function and hemostatic variables. Preoperative carprofen combined with mepivacaine epidural anesthesia had superior postoperative analgesia compared with preoperative carprofen alone. When preoperative epidural anesthesia was performed, preoperative administration of carprofen did not improve postoperative analgesia compared with postoperative administration of carprofen.

    The high prevalence of chronic persistent neck pain not only leads to disability but also has a significant economic, societal, and health impact. Among multiple modalities of treatments prescribed in the management of neck and upper extremity pain, surgical, interventional and conservative modalities have been described. Cervical epidural injections are also common modalities of treatments provided in managing neck and upper extremity pain. They are administered by either an interlaminar approach or transforaminal approach. To determine the long-term efficacy of cervical interlaminar and transforaminal epidural injections in the treatment of cervical disc herniation, spinal stenosis, discogenic pain without facet joint pain, and post surgery syndrome. The literature search was performed from 1966 to October 2014 utilizing data from PubMed, Cochrane Library, US National Guideline Clearinghouse, previous systematic reviews, and cross-references. The evidence was assessed based on best evidence synthesis with Level I to Level V. There were 7 manuscripts meeting inclusion criteria. Of these, 4 assessed the role of interlaminar epidural injections for managing disc herniation or radiculitis, and 3 assessed these injections for managing central spinal stenosis, discogenic pain without facet joint pain, and post surgery syndrome. There were 4 high quality manuscripts. A qualitative synthesis of evidence showed there is Level II evidence for each etiology category. The evidence is based on one relevant, high quality trial supporting the efficacy of cervical interlaminar epidural injections for each particular etiology. There were no randomized trials available assessing the efficacy of cervical transforaminal epidural injections. Paucity of available literature, specifically conditions other than disc herniation. This systematic review with qualitative best evidence synthesis shows Level II evidence for the efficacy of cervical interlaminar epidural injections with local

    Our aim was to evaluate the efficacy of clonidine with lidocaine as a local anaesthetic agent for inferior alveolar mandibular nerve blocks for dental extraction. We studied 200 patients who required extraction of mandibular teeth and divided them into two groups of 100 each, the first of which was given lidocaine and adrenaline (12.5μg/ml) and the second lidocaine and clonidine (15μg/ml). Cardiovascular vascular variables (blood pressure, heart rate, and mean arterial pressure) were assessed before, during, and after extraction, and postoperative pain was measured on a visual analogue scale. There was a significant reduction in systolic blood pressure (p=0.0001) and heart rate (p=0.000) after injection of clonidine. However, they both increased after injections of lidocaine plus adrenaline, and there was a significant reduction in pain at four hours postoperatively with clonidine (p=0.000). Our results showed that anaesthesia with lidocaine and clonidine decreases systolic blood pressure and heart rate 10minutes after injection for extraction of lower mandibular teeth. We suggest that patients who have local anaesthetic with lidocaine and clonidine are at minimal cardiovascular risk and there is no difference in the onset of anaesthesia.

    Epidural calcification is a rare cause of back pain, and spontaneous epidural calcification has not been reported previously. We describe a patient with acute low back pain and signs of lumbar nerve root compression due to epidural calcification, as demonstrated by CT-scan and MRI. Radiological signs of spondylodiscitis led to a search for an infectious cause, which was negative, and her symptoms responded rapidly to NSAID treatment alone. Her symptoms recurred 18 months later, and further imaging studies again revealed epidural calcification, but with a changed distribution. Her symptoms were relieved once more by NSAID treatment alone. We propose that epidural calcification secondary to aseptic spondylodiscitis is the main cause of acute back pain in this patient. A possible mechanism may be the pro-inflammatory effects of calcium pyrophosphate or hydroxyapatite crystal deposition within the epidural space. (orig.)

    Epidural morphine for postoperative pain relief is in general use, and has proved to be very efficient in adults. The epidural technique and the use of epidural morphine are much less frequent in children. For 2 years we have prospectively followed 76 children who had epidural morphine...... for postoperative pain relief after major abdominal surgery. The age distribution was from newborn to 13 years, with a median age of 12 months. It was estimated that 94% of the patients had good analgesia for the first 24 postoperative hours and no other opioids were given. The side effects were few, but one case...... the investigation. We observed a change in the sleeping pattern with an increased number of sleep-induced myoclonia during the administration of epidural morphine. In conclusion, the use of epidural morphine in children for postoperative pain relief is very efficient. The minimal effective dose has not been...

    Laparoscopic cholecystectomy (LC) has traditionally been performed under general anesthesia, however, owing in part to the advancement of surgical and anesthetic techniques, many laparoscopic cholecystectomies have been successfully performed under the spinal anesthetic technique. We hoped to determine the feasibility of segmental epidural anesthesia for LC. Twelve American Society of Anesthesiologists class I or II patients received an epidural block for LC. The level of epidural block and the satisfaction score of patients and the surgeon were checked to evaluate the efficacy of epidural block for LC. LC was performed successfully under epidural block, with the exception of 1 patient who required a conversion to general anesthesia owing to severe referred pain. There were no special postoperative complications, with the exception of one case of urinary retention. Epidural anesthesia might be applicable for LC. However, the incidence of intraoperative referred shoulder pain is high, and so careful patient recruitment and management of shoulder pain should be considered.

    Full Text Available Freedom from pain has almost developed to be a fundamental human right. Providing pain relief via epidural catheters in thoracic and upper abdominal surgeries is widely accepted. Pain relief through this technique not only provides continuous analgesia but also reduces post-operative pulmonary complications and also hastens recovery. But being a blind procedure it is accompanied by certain complications. Hypotension, dura puncture, high epidural, total spinal, epidural haematoma, spinal cord injury and infection are some of the documented side effects of epidural block. There are case reports eliciting neurological complications, catheter site infections, paresthesias, radicular symptoms and worsening of previous neurological conditions. Few technical problems related to breakage of epidural catheter are also mentioned in the literature. The patient had no sequelae on long term follow up even when a portion of catheter was retained. We present a case report where epidural catheter punctured pleura in a patient undergoing thoracotomy for carcinoma oesophagus.

    2012-09-01

    Full Text Available This study was conducted in 16 healthy immature dromedary camels weighing 120-150 kg to evaluate and compare the effects of epidural and intramuscular injections of xylazine administered at 0.1 mg/kg and 0.2 mg/kg. Haematological parameters included haemoglobin, packed cell volume, total erythrocyte count and total leukocyte count. Biochemical parameters included alkaline phosphates, alanine aminotransferase, aspartate aminotransferase, blood urea nitrogen, creatinine and glucose. Parameters were measured at different intervals before (baseline and after the administration of drugs. Our study showed that the effect of xylazine on haematological and biochemical parameters is dose-dependant and is also related to the route of administration. The low dose of xylazine administered using both intramuscular and epidural methods showed minimal effects, whereas high doses of the drug, especially when injected intramuscularly, caused greater changes in haematological and biochemical parameters.

    An 8-year-old boy developed vomiting and severe headache following minor head trauma. A CT scan of the head demonstrated a lytic lesion of the skull and adjacent epidural hematoma. Surgical evacuation and removal of the skull lesion and hematoma were carried out, and pathologic evaluation resulted in a diagnosis of Langerhans' cell histiocytosis (LCH). Epidural involvement of Langerhans' cell histiocytosis is very rare, and we report the first case of LCH presenting as an intracranial epidural hematoma. (orig.)

    Accelerometric tremorgrams were recorded from 25 subjects affected by essential tremor and analysed by a Berg-Fourier frequency analyser before and during venous infusion of the following drugs: propranolol (beta-blocker), clonidine (alpha-presynaptic adrenergic agonist), urapidil (alpha-postsynaptic blocker), trazodone (adrenolytic agent) and placebo. The washout interval between infusions was 3 days. Recordings and data analyses were performed in a double-blind crossover trial. Tremor was classified as: at rest; postural (arms hyperextended); and intention (finger-nose test). Analysis of the results showed that propranolol and clonidine reduced significantly (P = 0.01 and P = 0.009, respectively) the power spectrum of postural tremor, but left at rest and intention tremors unchanged. No significant effects on the tremor power spectrum were observed after placebo, urapidil or trazodone administration. None of the drugs had any effect on tremor frequency.

    Treatment outcomes were compared for 2 groups of subjects detoxified from methadone using clonidine. One group of 12 subjects was encouraged to continue in treatment with naltrexone, while the other 12 subjects did not have naltrexone treatment available. Results suggested that those subjects who had naltrexone available were more successful at completing the 10 day detoxification treatment and that the relapse rate at 30 days post-treatment was significantly reduced by naltrexone treatment.

    Highlights: • Image guided interventions focused to administer drugs inside the epidural space are effective in reducing the perceived spinal pain, but their efficacy seems to be limited in time. • To treat spinal pain with image guided interventions is safe and repeatable. • Sacroiliac dysfunction is a common cause of sciatica-like pain which can be treated with CT-guided interventions (both steroids and pulsed RF denervation). - Abstract: Objectives: To review the state-of-the-art of image – guided techniques used to treat painful syndromes of the lower back, their indications, how they should be performed, their related risks and the expected results. Methods: We describe the actual standards about image-guided infiltrative therapies both on spine and on sacroiliac joints. Results: Both spinal epidural and sacroiliac injections appear useful in a large percentage of treated patients to get control of the perceived pain. Performing these therapies under CT or fluoroscopic guidance is the best and safest way to obtain satisfactory results because it is possible to target the use of drugs directly to the involved painful structures. Conclusions: Image-guided injections of the epidural space and of the sacroiliac joints are effective techniques for the treatment of pain; their effectiveness is sometimes not lasting for long periods of time but considering the low associated risk when performed by trained personnel, they can be easily repeated

    The effect of epidural administered xylazine was investigated in 10 mature Holstein cows (mean age: 5.4 +/- 1.2 years, mean BW: 572 +/- 23 kg): 5 cows were treated with xylazine in a low dose of 0.05 mg/kg body weight, 3 cows in a medium dose (0.07 mg/kg BW) and 2 cows in a high dose (0.1 mg/kg BW). Xylazine dosages were diluted in sterile saline to a final volume of 5 ml. As a control, lidocaine (5 ml of a 2% solution) was given to 5 cows epidurally. Duration of regional anaesthesia after low dose of xylazine (0.05 mg/kg BW) was significant longer (mean: 2.2 hours) compared to lidocaine treated cows (mean: 1.1 hour). Regional extension of anaesthesia was comparable after dosing with xylazine and lidocaine (tail, after, vulva and perineum). All cows remained standing, but in xylazine treated cows systemic effects, e.g. mild sedation, decreased heart- and respiratory rates, decreased rumen motility and mild bloat were observed. With increased dosages of xylazine a prolongation of epidural anaesthesia up to 3 hours was achieved, but regional extension of this effect remained nearly unchanged. With increased xylazine dosages, cows showed marked sedation and ataxia and sternal recumbency were induced.

    Full Text Available Epidural analgesia is commonly used in large animals. It is an easy, cheap, and effective technique used to prevent or control pain during surgeries involving the tail, anus, vulva, perineum, caudal udder, scrotum, and upper hind limbs. The objectives of this article were to comprehensively review and summarize all scientific data available in the literature on new techniques and drugs or drug combinations used for epidural anesthesia in cattle, camel, and buffalo. Only articles published between 2006 and 2016 were included in the review. The most common sites for epidural administration in cattle, camels, and buffalos were the sacrococcygeal intervertebral space (S5-Co1 and first intercoccygeal intervertebral space (Co1-Co2. The most frequently used drugs and dosages were lidocaine (0.22-0.5 mg/kg, bupivacaine (0.125 mg/kg, ropivacaine (0.11 mg/kg, xylazine (0.05 mg/kg, medetomidine (15 μg/kg, romifidine (30-50 μg/kg, ketamine (0.3-2.5 mg/kg, tramadol (1 mg/kg, and neostigmine (10 μg/kg, and the clinical applications, clinical effects, recommendations, and side effects were discussed.

    Full Text Available Objectives: Unlike most other Analgesic drugs, α2 adrenoceptor agonists are capable of producing analgesia. The aim of this study was to evaluate the Analgesic and antisympathetic effects of clonidine, an α2 adrenoceptor agonist in burn patients. Materials and Methods: This randomized, double-blind, placebo-controlled clinical trial performed on one hundred burn patients in Zarea Hospital, Mazandaran, Iran from august 2004 to July 2005. All patients divided in two groups. Case group (n=50 received oral clonidine, 3.3μg/kg TDS and controls (n=50 received placebo. Heart rate and systolic blood pressure and pain severity Visual analogue score (VAS, were recorded after clonidine administration. Statistical analysis was done by means of Mann Witney U test. Results: 50 patients (mean age 28.96±10 years in case group, and 50 patients (mean age 27.60±11.4 years in control group were studied. VAS pain scores and heart rate in the clonidine group were significantly lower than the control group (P< 0.0001, P< 0.02.there were no significant difference in systolic blood pressure between the two groups on the first and second day but on third day the systolic blood pressure in clonidine group, was lower than controls significantly (P=0.002. Conclusion: This study demonstrates that the use of oral clonidine affects the hemodynamic response to pain in burn patients. Our study demonstrated that clonidine can produce good analgesia and decreased in sympathetic over activity in burn patients, and also reduce opioid dose requirements.

    Full Text Available Background : The addition of clonidine to lidocaine intravenous regional anesthesia (IVRA has been previously reported to improve postoperative analgesia in patients undergoing upper extremity surgery. Our objective was to perform a dose ranging study in order to determine the optimal dose of clonidine used with lidocaine in IVRA. Design & Setting : We performed a double-blinded randomized placebo-controlled study with 60 patients scheduled for elective endoscopic carpal tunnel release under IVRA with 50 ml lidocaine 0.5%. University-affiliated outpatient surgery center. Data collected in operating rooms, recovery room, and by telephone after discharge from surgery center. Materials & Methods : Sixty adult ASA I or II patients undergoing outpatient endoscopic carpal tunnel release under intravenous regional anesthesia.Patients were randomized into five study groups receiving different doses of clonidine in addition to 50 ml 0.5% lidocaine in their IVRA. Group A received 0 mcg/kg, group B 0.25 mcg/kg, group C 0.5 mcg/kg, group D 1.0 mcg/kg and group E 1.5 mcg/kg of clonidine.Intraoperative fentanyl, recovery room pain scores, time to first postsurgical analgesic, total number of acetaminophen/codeine tablets consumed postsurgery, incidence of sedation, hypotension and bradycardia. Results & Conclusions : There was no benefit from any dose of clonidine compared to placebo. There were no clonidine-related side effects seen within the dose range studied. In short duration minor hand surgery, the addition of clonidine to lidocaine-based intravenous regional anesthesia provides no measurable benefit.

    Patients with hyperthyroidism have reduced growth hormone (GH) responses to pharmacological stimuli and reduced spontaneous nocturnal GH secretion. The stimulatory effect of clonidine on GH secretion has been suggested to depend on an enhancement of hypothalamic GH-releasing hormone (GHRH) release. The aim of our study was to evaluate the effects of clonidine and GHRH on GH secretion in patients with hyperthyroidism. Eight hyperthyroid females with recent diagnosis of Graves' disease (age range 20-55 years, body mass index range 19.2-26.2 kg/m2) and 6 healthy female volunteers (age range 22-35 years, body mass index range 19-25 kg/m2) underwent two experimental trials at no less than 7-day intervals: (a) an intravenous infusion of clonidine 150 micrograms in 10 ml of saline, or (b) a bolus intravenous injection of human GHRH (1-29)NH2, 100 micrograms in 1 ml of saline. Hyperthyroid patients showed blunted GH peaks after clonidine (7.1 +/- 1.7 micrograms/l) as compared to normal subjects receiving clonidine (28.5 +/- 4.9 micrograms/l, p less than 0.05). GH peaks after GHRH were also significantly lower in hyperthyroid subjects (8.0 +/- 1.7 micrograms/l) as compared to normal subjects receiving GHRH (27.5 +/- 4.4 micrograms/l, p less than 0.05). No significant differences in the GH values either after clonidine or GHRH were observed in the two groups of subjects examined. Our data demonstrate that the GH responses to clonidine as well as to GHRH in patients with hyperthyroidism are inhibited in a similar fashion with respect to normal subjects.(ABSTRACT TRUNCATED AT 250 WORDS)

    Incorrect placement of the needle causes medical complications in the epidural block, such as dural puncture or spinal cord injury. This study proposes a system which combines an optical coherence tomography (OCT) imaging probe with an automatic identification (AI) system to objectively identify the position of the epidural needle tip. The automatic identification system uses three features as image parameters to distinguish the different tissue by three classifiers. Finally, we found that the support vector machine (SVM) classifier has highest accuracy, specificity, and sensitivity, which reached to 95%, 98%, and 92%, respectively.

    Ropivacaine is amide local anaesthetic pure S(-)enantiomer of bupivacaine. Its duration of analgesia is similar to that of Bupivacaine (in equivalent doses) but the motor block is slower in onset, less intense, shorter in duration for a given level of sensory block with lesser cardiac side effects but addition of an adjuvant like clonidine which is an imidazoline derivative has been studied for its sedative, anxiolytic and analgesic properties. This study was aimed to show the optimum concentrations of Ropivacaine and Clonidine to maximize analgesia without side effects by evaluating its safety and efficacy. Sixty children aged 2-10 years of ASA grade 1, scheduled to undergo infraumbilical surgeries were randomly allocated to Group A & Group B of 30 each. Group A received 0.2% Ropivacaine with normal saline and Group B received 0.2% Ropivacaine and preservative free Clonidine 1μg/kg, the total volume of solution being 1ml/kg haemodynamic changes were monitored intraoperatively and haemodynamic parameters along with motor blockade, pain score and sedation score were assessed postoperatively. Done with unpaired student t and Mann-Whitney test. The groups were comparable regarding demographic characterstics. The mean duration of analgesia was prolonged in group B (12+2.22 hours) than in group A (6.53+1.16 hours) with p-value <0.001 leading to less rescue analgesia in former group. None of the children in the groups had a pain score of ≥ 4 at the end of 2 hours. A 6.6% and 60% of group A children had score of ≥ 4 at the end of 4(th) & 6(th) hour respectively. None in Group B had a score of ≥ 4. At the end of 8(th) hour, only 6.6% of the children in Group B had a pain score of ≥ 4 whereas it was 33.33% in Group A which is statistically significant. No bradycardia or hypotension and no significant sedation. Combination of Ropivacaine and Clonidine in the concentration used (0.2% ropivacaine and 1μg/kg of clonidine) can be optimal for postoperative analgesia in

    Epidural analgesia is an effective and popular way to relieve labour pain but it may interfere with normal mechanism of labour. The objective of this study was to evaluate the outcome of labour in women with effective epidural analgesia in terms of duration of labour, mode of delivery and neonatal outcome. Methods: This was a quasi-experimental study conducted in the Department of Obstetrics and Gynaecology, Shaikh Zayed Federal Postgraduate Medical Institute and Hospital, Lahore. One hundred pregnant women were selected by non-probability convenient sampling method. Subjects were divided into two groups of 50 each as per convenience. Patients of any gravidity at term from 37-41 weeks were included in the sample. Epidural analgesia was applied to group B and distilled water to group A at the lumber region and the progress of labour, mode of delivery and effects on Apgar scores of neonates were evaluated. Out of hundred patients, 77 had normal duration of second stage while 23 had prolonged second stage. Among them, 18 patients (36%) were in epidural group and 5 patients (10%) in non-epidural group, while 4 patients (8%) in epidural group developed intra-partum complications; whereas among non-epidural group had such complications. 65 patients had spontaneous vaginal delivery while 35 patients had instrumental delivery. Among them 29 patients (58%) were in epidural group while only 6 patients (12%) were in non-epidural group. Babies born had Apgar score 5/10 (21.8%), 6/10 (59.4%) and 7/10 (17.8%) at 1 minute and 8/10 (74.3%) and 9/10 (24.8%) at 5 minutes in both groups and none of them needed bag and mask resuscitation. Conclusion: Epidural analgesia does prolong the duration of second stage of labour and increases the instrumental delivery rate. Neonatal outcome is satisfactory while only a few intra-partum complications are found with epidural analgesia. (author)

    Inadvertent dural puncture during epidural anesthesia leads to intracranial hypotension, which if left unnoticed can cause life-threatening subdural hematomas or cerebellar tonsillar herniation. The highly variable presentation of intracranial hypotension hinders timely diagnosis and treatment. We present the case of a young laboring adult female, who developed subdural hygromas and a subdural hematoma following unintentional dural puncture during initiation of epidural anesthesia.

    Propranolol has been shown previously to restore bone marrow function and improve anemia after lung contusion/hemorrhagic shock. We hypothesized that daily clonidine administration would inhibit central sympathetic outflow and restore bone marrow function in our rodent model of lung contusion/hemorrhagic shock with chronic stress. Male Sprague-Dawley rats underwent 6 days of restraint stress after lung contusion/hemorrhagic shock during which the animals received clonidine (75 μg/kg) after the restraint stress. On postinjury day 7, we assessed urine norepinephrine, blood hemoglobin, plasma granulocyte colony stimulating factor, and peripheral blood mobilization of hematopoietic progenitor cells, as well as bone marrow cellularity and erythroid progenitor cell growth. The addition of clonidine to lung contusion/hemorrhagic shock with chronic restraint stress significantly decreased urine norepinephrine levels, improved bone marrow cellularity, restored erythroid progenitor colony growth, and improved hemoglobin (14.1 ± 0.6 vs 10.8 ± 0.6 g/dL). The addition of clonidine to lung contusion/hemorrhagic shock with chronic restraint stress significantly decreased hematopoietic progenitor cells mobilization and restored granulocyte colony stimulating factor levels. After lung contusion/hemorrhagic shock with chronic restraint stress, daily administration of clonidine restored bone marrow function and improved anemia. Alleviating chronic stress and decreasing norepinephrine is a key therapeutic target to improve bone marrow function after severe injury. Copyright © 2016 Elsevier Inc. All rights reserved.

    Free epidural fat-grafting was performed to prevent adhesion between scar tissue of the epidural space and dura and nerve root after lumbar laminectomy. The results were evaluated using MRI. Fifteen cases were operated upon with an average follow-up period of 7.5 months. MRI was recorded and the findings were classified into four types as follow: I, equally high signal case; II, slight fibrosis case; III, severe fibrosis case; IV, high signal disappeared case. The results showed 3 cases of type I, 7 cases of type II, 3 cases of type III, and 2 cases of type IV. According to MRI findings, free epidural fat is supposed to be still viable and alive, although slightly fibroses but the dural side remains a high signal area. Free epidural fat-grafting was useful for preventing adhesion around the epidural space. There was high relationship to age and sex with regard to viability of the free fat graft. (author)

    Opium is a highly addictive agent and the most common narcotic often misused in Iran. The pharmacokinetic of anesthetic drugs in patients with opium addiction is one of the great challenges for anesthesiologists. Hemodynamic instability and postoperative side effects are of these challenges which should be managed correctly. In this study we aimed to assess the effects of clonidine upon post anesthesia shivering and recovery time in patients with and without opium addiction after general anesthesia to decrease the subsequent complications related to the shivering and elongation of recovery time. In a randomized clinical trial, 160 patients candidates for elective leg fracture operations under general anesthesia were studied in four groups of 40 patients: Group 1 (placebo 1) were patients without addiction who got placebo 90 minutes before the operation. Group 2 (placebo 2) were patients with opium addiction which received placebo as group 1. Group 3 (Clonidine 1) patients without addiction who got clonidine 90 minutes before the operation and group 4 (Clonidine 2) who were opium addicted ones which received clonidine as premedication. None of the patients with and without addiction in clonidine groups had shivering after the operation but in placebo groups shivering was observed and the difference between clonidine and placebo groups was statistically significant (P opium addicted than non-addicted patients (P = 0.04). Premedication with clonidine in patients with and without opium addiction can be effective to decrease the incidence of shivering and recovery time after operation.

    Full Text Available Background: Epidural analgesia is claimed to result in prolonged labor. Previous studies have assessed epidural analgesia vs systemic opioids rather than to parturients receiving no analgesia. This study aimed to evaluate the effect of epidural analgesia on labor duration compared with parturients devoid of analgesia. Methods: One hundred sixty nulliparous women in spontaneous labor at full term with a singleton vertex presentation were assigned to the study. Parturients who request epidural analgesia were allocated in the epidural group, whereas those not enthusiastic to labor analgesia were allocated in the control group. Epidural analgesia was provided with 20 mL bolus 0.5% epidural lidocaine plus fentanyl and maintained at 10 mL for 1 h. Duration of the first and second stages of labor, number of parturients receiving oxytocin, maximal oxytocin dose required for each parturient, numbers of instrumental vaginal, vacuum-assisted, and cesarean deliveries and neonatal Apgar score were recorded. Results: There was no statistical difference in the duration of the active-first and the second stages of labor, instrumental delivery, vacuum-assisted or cesarean delivery rates, the number of newborns with 1-min and 5-min Apgar scores less than 7 between both groups and number of parturients receiving oxytocin, however, the maximal oxytocin dose was significantly higher in the epidural group. Conclusion: Epidural analgesia by lidocaine (0.5% and fentanyl does not prolong labor compared with parturients without analgesia; however, significant oxytocin augmentation is required during the epidural analgesia to keep up the aforementioned average labor duration.

    Opacification of collateral pathways other than the central channels is very rare in lumbar epidural venography. Two cases of opacification of the inferior mesenteric vein following extravasation of contrast medium at the tip of the lateral sacral vein catheter are reported. One case is presented in which filling of normal parametrial venous plexuses and the left ovarian vein occurred as a consequence of incompetent or absent valves in the internal iliac vein. The literature containing comparable collateral flow patterns in disease is reviewed. The significance of the phlebographic features in our cases is discussed. (orig.)

  9. Epidural Labor Analgesia and Maternal Fever.

    2017-06-01

    Women receiving an epidural for labor analgesia are at increased risk for intrapartum fever. This relationship has been supported by observational, before and after, and randomized controlled trials. The etiology is not well understood but is likely a result of noninfectious inflammation as studies have found women with fever have higher levels of inflammatory markers. Maternal pyrexia may change obstetric management and women are more likely to receive antibiotics or undergo cesarean delivery. Maternal pyrexia is associated with adverse neonatal outcomes. With these consequences, understanding and preventing maternal fever is imperative.

  10. An epidural catheter removal after recent percutaneous coronary intervention and coronary artery stenting: Epidural catheter and antiaggregation therapy

    2016-01-01

    Full Text Available Introduction: Anticoagulation and antiplatelet therapy in the presence of the epidural catheter is still controversial. It is well known that dual antiplatelet therapy is indicated for 12 months after the placement of drug-eluting stents (DES. Removal of an epidural catheter during that period is related to an increased risk of stent occlusion in case of discontinuation of platelet function inhibitors or, on the other hand, increased risk of epidural hematoma associated with neurological deficit if suppressed platelet function is still present. Case Report: Here we present a case of a 63-year-old man who was admitted to Institute for Cardiovascular Diseases Dedinje for elective aortic surgery. Before the induction, an epidural catheter was inserted at the Th10-Th11 epidural space. Uneventful surgery was performed under the combined epidural and general anesthesia. On the 2nd postoperative day, the patient sustained a ST depression myocardial infarction treated with percutaneous coronary intervention with DES placement, while epidural catheter was still in place. Dual antiplatelet therapy with 600mg of clopidogrel, 100 mg of acetilsalicylic acid (ASA and low molecular weight heparin (LMWH were started during the procedure. The next day, clopidogrel (75 mg and ASA (100 mg were continued as well as LMWH. The decision to remove the epidural catheter was made on the 9th postoperative day, after platelet aggregation assays were performed. Six hours after catheter removal the patient again received clopidogrel, ASA and LMWH. There were no signs of epidural hematoma. Conclusion: This case shows that point-of-care testing with platelet aggregation assays may be useful in increasing the margin of safety for epidural catheter removal during dual antiplatelet therapy.

    It has been suggested that pain control during intracavitary brachytherapy for cervical cancer is insufficient in most hospitals in Japan. Our hospital began using caudal epidural anesthesia during high-dose-rate (HDR) intracavitary brachytherapy in 2011. The purpose of the present study was to retrospectively investigate the effects of caudal epidural anesthesia during HDR intracavitary brachytherapy for cervical cancer patients. Caudal epidural anesthesia for 34 cervical cancer patients was performed during HDR intracavitary brachytherapy between October 2011 and August 2013. We used the patients' self-reported Numeric Rating Scale (NRS) score at the first session of HDR intracavitary brachytherapy as a subjective evaluation of pain. We compared NRS scores of the patients with anesthesia with those of 30 patients who underwent HDR intracavitary brachytherapy without sacral epidural anesthesia at our hospital between May 2010 and August 2011. Caudal epidural anesthesia succeeded in 33 patients (97%), and the NRS score was recorded in 30 patients. The mean NRS score of the anesthesia group was 5.17 ± 2.97, significantly lower than that of the control group's 6.80 ± 2.59 (P = 0.035). The caudal epidural block resulted in no side-effects. Caudal epidural anesthesia is an effective and safe anesthesia option during HDR intracavitary brachytherapy for cervical cancer. (author)

    Epidural route is preferable for postoperative pain relief in thoraco-abdominal and lower limb surgeries. We aimed to compare epidural butorphanol versus morphine for postoperative analgesia up to 24 hours in open nephrectomy surgery. 80 ASA physical status I and II adult patients were selected for this randomized double blind prospective study. A standard balanced general anesthesia technique was applied for all patients. Epidural catheter was placed in lower thoracic inter-vertebral space before the start of surgery. Injection butorphanol 0.04 mg/kg in group B (n = 40) or morphine 0.06 mg/kg in group M (n = 40) was given in a double blind manner after completion of surgery and before extubation through the epidural catheter. Patients were observed for pain relief by Visual Analogue Scale (VAS) for the next 24 hours. Dose was repeated when VAS was > 4. The onset and peak effect of pain relief, duration of analgesia of 1st dose, frequency of drug administration and side effects if any were observed. The average onset of analgesia was 26.5 +/- 7.61 minutes with butorphanol and 62.5 +/- 13.4 minutes with morphine group which was statistically significant (p < 0.05). The mean peak effect of pain relief following 1st dose was 173 +/- 51.25 minutes with butorphanol and 251 +/- 52.32 minutes with morphine group. The duration of pain relief after 1st dose was statistically significant and was 339.13 +/- 79.57 minutes in group B and 709.75 +/- 72.12 minutes in group M which was gradually increased on repeated dosing in group B while it was almost same in Group M. Number of doses required in 24 hours was significantly higher (p < 0.05) in butorphanol group than morphine group. Somnolence was the main side effect in group B while pruritus was the main side effect with group M. Epidural butorphanol appears to provide safer and faster postoperative analgesia without much untoward effects but its analgesic action is short so more repeated doses are required than morphine via

    The language structures used by antenatal educators have not been previously researched in the context of antenatal childbirth classes. Epidural analgesia for labour is a common, and a frequently asked about, component of antenatal education for parents in hospitals providing maternity care. We aimed to identify the way information is described and presented by childbirth educators to assess content and determine which language structures such as metaphor, suggestion, information and storytelling are utilized. This observational study of antenatal education was conducted at a single tertiary referral center for maternity care in Western Sydney, Australia. All three childbirth educators agreed to be video recorded whilst providing information to parents during antenatal classes. Audio data was subsequently transcribed and then analysed by two researchers, independently categorising the various language structures and types of information provided. For the purposes of the current study, data concerning a single topic was used for the analysis-'epidural analgesia for labour'. Language structures used were highly variable between educators, as was the content and time taken for the information being provided. Our findings represent a first attempt to identify baseline information used in the clinical setting of antenatal education in order to categories communication structures used. This study has identified areas for further improvements and consistency in the way educators provide information to parents and has important implications for future midwifery practice, education and research.

    The authors report a case of intracranial epidural hemorrhage (ICEH) during spinal surgery. We could not find ICEH, though we recorded transcranial electrical stimulation motor evoked potentials (TcMEPs). A 35-year-old man was referred for left anterior thigh pain and low back pain that hindered sleep. Sagittal T2-weighted magnetic resonance imaging revealed an intradural tumor at L3-L4 vertebral level. We performed osteoplastic laminectomy and en bloc tumor resection. TcMEPs were intraoperatively recorded at the bilateral abductor digiti minimi (ADM), quadriceps, tibialis anterior and abductor hallucis. When we closed a surgical incision, we were able to record normal TcMEPs in all muscles. The patient did not fully wake up from the anesthesia. He had right-sided unilateral positive ankle clonus 15 min after surgery in spite of bilateral negative of ankle clonus preoperatively. Emergent brain computed tomography scans revealed left epidural hemorrhage. The hematoma was evacuated immediately via a partial craniotomy. There was no restriction of the patient's daily activities 22 months postoperatively. We should pay attention to clinical signs such as headache and neurological findgings such as DTR and ankle clonus for patients with durotomy and cerebrospinal fluid (CSF) leakage. Spine surgeons should know that it was difficult to detect ICEH by monitoring with TcMEPs.

    Full Text Available Spontaneous pneumomediastinum is a relatively rare benign condition. It may rarely be associated with one or combination of pneumothorax, epidural pneumatosis, pneumopericardium, or subcutaneous emphysema. We present a unique case with four of the radiological findings in a 9-year-old male child who presented to our emergency department with his parents with complaints of unproductive cough, dyspnea, and swelling on chest wall. Bilateral subcutaneous emphysema was palpated on anterior chest wall from sternum to midaxillary regions. His anteroposterior and lateral chest radiogram revealed subcutaneous emphysema and pneumomediastinum. His thorax computed tomography to rule out life-threatening conditions revealed bilateral subcutaneous, mediastinal, pericardial, and epidural emphysema without pneumothorax. He was transferred to pediatric intensive care unit for close monitorization and conservative treatment. He was followed-up by chest radiographs. He was relieved from symptoms and signs around the fifth day and he was discharged at the seventh day. Diagnosis of pneumomediastinum is often made based on physical findings and plain radiographs. It may not be as catastrophic as it is seen. Close cardiopulmonary monitorization is mandatory for complications and accompanying conditions. Most patients with uncomplicated spontaneous pneumomediastinum respond well to oxygen and conservative management without any specific treatment.

    During four year period from April, 1977 to March, 1981, 53 cases with acute traumatic epidural hematoma had been encountered out of 430 acute head injured patients examined by computerized tomography (CT) within 24 hours after incurring the trauma. Besides the initial CT, the authors performed contrast enhanced CT (41 cases) and serial CT scanning (31 cases). There were 49 cases of epidural hematoma existing in the supratentorial region, Two cases infratentorial region and 2 cases in the both regions. Two cases of vertex epidural hematoma had been encountered, one of them required vertical scan technique. In 22 (41%) of the 53 patients, the initial CT showed evidence of other cerebral lesions. The most frequent lesion was pneumocephalus (11 cases), 3 cases of them existed in the epidural hematoma. There were also intracerebral hematoma (6 cases), subdural hematoma (4 cases), cerebral contusion (2 cases), intraventricular hemorrhage (2 cases) and 2 cases of them demonstrated ''diffuse traumatic cerebral injury''. During contrast enhanced CT, 11 cases out of 41 cases indicated several enhancement pattern. There were total enhancement of epidural hematoma (2 cases), partial enhancement of hematoma (2 cases) and enhancement of internal margin of hematoma (2 cases). Serial CT scans was performed in 36 out of the 53 patients. Common findings on the serial CT scans were decreased density collection in the subdural space such as subdural effusions or chronic subdural hematomas (8 cases) and enlargement of small epidural hematomas (3 cases). After evacuation of epidural hematoma, there were some cases showing the so-called ''delayed traumatic intracerebral hematoma'' (4 cases), appearance of other epidural hematoma (1 case) and development of small cerebral infarction in the basal ganglia. There was one case indicating appearance of a new epidural hematoma contra lateral to the side of evacuation of subdural hematoma. (J.P.N.)

    Full Text Available Patient controlled epidural analgesia (PCEA is a well established technique for pain relief during labor. But the inclusion of continuous background infusion to PCEA is controversial. The aim of this study was to assess whether the use of continuous infusion along with PCEA was beneficial for laboring women with regards to quality of analgesia, maternal satisfaction and neonatal outcome in comparison to PCEA alone. Fifty five parturients received epidural bolus of 10ml solution containing 0.125% bupivacaine +2 ìg.ml-1 of fentanyl. For maintenance of analgesia the patients of Group PCEA self administered 8 ml bolus with lockout interval of 20 minutes of above solution on demand with no basal infusion. While the patients of Group PCEA + CI received continuous epidural infusion at the rate of 10 ml.hr-1 along with self administered boluses of 3 ml with lockout interval of 10 minutes of similar epidural solution. Patients of both groups were given rescue boluses by the anaesthetists for distressing pain. Verbal analogue pain scores, incidence of distressing pain, need of supplementary/rescue boluses, dose of bupivacaine consumed, maternal satisfaction and neonatal Apgar scores were recorded. No significant difference was observed between mean VAS pain scores during labor, maternal satisfaction, mode of delivery or neonatal Apgar scores. But more patients (n=8 required rescue boluses in PCEA group for distressing pain. The total volume consumed of bupivacaine and opioid was slightly more in PCEA + CI group. In both the techniques the highest sensory level, degree of motor block were comparable& prolongation of labor was not seen. It was concluded that both the techniques provided equivalent labor analgesia, maternal satisfaction and neonatal Apgar scores. PCEA along with continuous infusion at the rate of 10 ml/ hr resulted in lesser incidence of distressing pain and need for rescue analgesic. Although this group consumed higher dose of bupivacaine

    2012-01-01

    Full Text Available There is increasing evidence that children suffer from the consequences of spontaneous or iatrogenic intracranial hypotension. Pediatric epidural blood patch is gaining popularity because of its ability to alter cerebrospinal fluid dynamics and to alleviate headaches attributed to low cerebrospinal fluid pressure. There is, however, still not enough data to document the safety profile of an epidural blood patch. Here we describe a case of a fever in a child temporally related to the administration of an epidural blood patch. This case depicts the dilemmas in making the diagnosis and instituting treatment for complications of this procedure in the pediatric population.

  1. Measurements of Epidural Space Depth Using Preexisting CT Scans Correlate with Loss of Resistance Depth during Thoracic Epidural Catheter Placement

    Full Text Available Background. Thoracic epidural catheters provide the best quality postoperative pain relief for major abdominal and thoracic surgical procedures, but placement is one of the most challenging procedures in the repertoire of an anesthesiologist. Most patients presenting for a procedure that would benefit from a thoracic epidural catheter have already had high resolution imaging that may be useful to assist placement of a catheter. Methods. This retrospective study used data from 168 patients to examine the association and predictive power of epidural-skin distance (ESD on computed tomography (CT to determine loss of resistance depth acquired during epidural placement. Additionally, the ability of anesthesiologists to measure this distance was compared to a radiologist, who specializes in spine imaging. Results. There was a strong association between CT measurement and loss of resistance depth (P35 changed this relationship (P=0.007. The ability of anesthesiologists to make CT measurements was similar to a gold standard radiologist (all individual ICCs>0.9. Conclusions. Overall, this study supports the examination of a recent CT scan to aid in the placement of a thoracic epidural catheter. Making use of these scans may lead to faster epidural placements, fewer accidental dural punctures, and better epidural blockade.

  2. Clonidine treatment delays postnatal motor development and blocks short-term memory in young mice.

    Directory of Open Access Journals (Sweden)

    Cristina Calvino-Núñez

    Full Text Available During the development of the nervous system, the perinatal period is particularly sensitive as neuronal connections are still forming in the brain of the neonate. Alpha2-adrenergic receptors are overexpressed temporarily in proliferative zones in the developing brain, reaching a peak during the first postnatal week of life. Both stimulation and blocking of these receptors during this period alter the development of neural circuits, affecting synaptic connectivity and neuronal responses. They even affect motor and cognitive skills later on in the adult. It's especially important to look for the early neurological consequences resulting from such modifications, because they may go unnoticed. The main objective of the present study has been to reaffirm the importance of the maturation of alpha-adrenergic system in mice, by carrying out a comprehensive examination of motor, behavioral and cognitive effects in neonates, during early postnatal development, following chronic administration of the drug Clonidine, an alpha2 adrenergic system agonist. Our study shows that mice treated postnatally with clonidine present a temporal delay in the appearance of developmental markers, a slow execution of vestibular reflexes during first postnatal week of life and a blockade of the short term memory in the novel object recognition task. Shortly after the treatment the startle response is hyperreactive.

    Elucidation of the structure of the endogenous ligand(s) for imidazoline binding sites, clonidine-displacing substance (CDS), has been a major goal for many years. Crude CDS from bovine lung was purified by reverse-phase high-pressure liquid chromatography. Electrospray mass spectrometry (ESMS) and nuclear magnetic resonance ((1)H NMR) analysis revealed the presence of L-tryptophan and 1-carboxy-1-methyltetrahydro-beta-carboline in the active CDS extract. Competition radioligand binding studies, however, failed to show displacement of specific [(3)H]clonidine binding to rat brain membranes for either compound. Further purification of the bovine lung extract allowed the isolation of the beta-carbolines harmane and harmalan as confirmed by ESMS, (1)H NMR, and comparison with synthetic standards. Both compounds exhibited a high (nanomolar) affinity for both type 1 and type 2 imidazoline binding sites, and the synthetic standards were shown to coelute with the active classical CDS extracts. We therefore propose that the beta-carbolines harmane and harmalan represent active components of classical CDS. The identification of these compounds will allow us to establish clear physiological roles for CDS.

    Objective: To study the pathogenesis of acute spinal epidural hematomas (ASEHs), MRI features, and its value on diagnosis and differential diagnosis. Methods: Fifteen patients with ASEHs (8 males, 7 females, mean age 37.8 years) were reviewed. Seven of the patients were secondary to spinal injuries (5 spinal trauma, 1 post-spinal operation, and 1 post-lumbar puncture) and 8 were spontaneous. Eleven patients were confirmed by operation. MRI was performed in all patients in sagittal SE T 1 WI and SE or FSE T 2 WI, 12 in axial FSE T 2 WI, 8 in axial SE T 1 WI, and 4 in contrast-enhanced SE T 1 WI. Results: Fifteen ASEHs involved 18 spinal segments, 6 of the segments (6/18) in cervical spine, 9 segments (9/18) in thoracic spine, and 3 segments (3/18) in lumbar spine. The hematomas located at pre-epidural space in 7 segments (7/18) and at posterolateral epidural space in 11 segments (11/18). The craniocaudal extent of the hematomas varied from 1 to 13 vertebral levels (average 4.87 vertebral level). There were low signal intensity lines between hematomas and spinal cord in all of the cases on T 1 WI. The low signal intensity line between hematoma and subarachnoid space was demonstrated in 8 cases (8/12) and 4 cases (4/15) on axial T 2 WI and sagittal T 2 WI, respectively. The figure of hematomas was biconvex on axial imaging in all of the cases, and long lentiform on sagittal imaging in 13 cases (13/15). The hematomas showed variable signal intensity. On T 1 WI, 5 showed isointensity to cord, 6 with hyperintensity, and 4 with inhomogeneous iso-hyperintensity. On T 2 WI, 5 showed hypointensity, 10 with inhomogeneous hypo-hyperintensity. There was no special MR manifestation after contrast administration. Conclusion: ASEHs is a rare disorder, and MRI features are characteristic for the diagnosis and differential diagnosis

    To assess the potential of antihypertensive drugs for interference with somatic growth and sexual development in hypertensive children, the effect of clonidine therapy on various endocrine, cardiovascular, and neuromuscular functions has been examined in five male adolescents with idiopathic hypertension. In studies done before and at the end of 4 weeks of twice-daily clonidine therapy, in an average daily dose of 0.31 mg, no significant effects were noted in the secretory patterns of growth hormone, luteinizing hormone, follicle-stimulating hormone, prolactin, cortisol, aldosterone, or testosterone, measured in blood obtained every 20 minutes for 24 hours. In blood obtained while the patients were supine and then erect, plasma renin activity and norepinephrine levels were significantly lowered after clonidine therapy. Cardiovascular responses to dynamic exercise were little altered beyond a 17% decrease in maximal oxygen consumption. The performance of fine motor skills was minimally altered. These data provide preliminary evidence that clonidine, an antihypertensive drug that affects the adrenergic nervous system, may not interfere with normal growth and maturation in adolescent males.

  8. Paraplegia following epidural analgesia: A potentially avoidable cause?

    Directory of Open Access Journals (Sweden)

    Jeson R Doctor

    2014-01-01

    Full Text Available Neurological deficit is an uncommon but catastrophic complication of epidural anesthesia. Epidural hematomas and abscesses are the most common causes of such neurological deficit. We report the case of a patient with renal cell carcinoma with lumbar vertebral metastasis who developed paraplegia after receiving thoracic epidural anesthesia for a nephrectomy. Subsequently, on histo-pathological examination of the laminectomy specimen, the patient was found to have previously undiagnosed thoracic vertebral metastases which led to a thoracic epidural hematoma. In addition, delayed reporting of symptoms of neurological deficit by the patient may have impacted his outcome. Careful pre-operative investigation, consideration to using alternative modalities of analgesia, detailed patient counseling and stringent monitoring of patients receiving central neuraxial blockade is essential to prevent such complications.

    1982-01-01

    35 patients with epidural bleeding operated on at Rikshospitalet, Oslo, during the period 1965 - 1980 had preoperative angiography with visualization of the external carotid artery. Twenty-one patients had extravasation of contrast medium from meningeal arteries. Seventeen of the 21 had also shunting of contrast medium from meningeal arteries to meningeal or diploic veins, while 20 of the 21 also had bled from a ruptured meningeal artery at operation. It was further found that of 20 patients who deteriorated after trauma 18 had an epidural arteriovenous shunt or extravasation. Conversely, of 15 patients who improved after trauma 12 had no evidence of a shunt. The strong correlation between the clinical course and the occurrence of extravasation supports previous experimental and clinical data, indicating the epidural arteriovenous shunt to be a major factor in the pathophysiology and the outcome of epidural bleeding.

  13. Epidural analgesia for labour: maternal knowledge, preferences and informed consent.

    LENUS (Irish Health Repository)

    2012-02-29

    Epidural analgesia has become increasingly popular as a form of labour analgesia in Ireland. However obtaining true inform consent has always been difficult. Our study recruited 100 parturients who had undergone epidural analgesia for labour, aimed to determine the information they received prior to regional analgesia, and to ascertain their preferences regarding informed consent. Only 65 (65%) of patients planned to have an epidural. Knowledge of potential complications was variable and inaccurate, with less than 30 (30%) of women aware of the most common complications. Most women 79 (79%) believed that discomfort during labour affected their ability to provide informed consent, and believe consent should be taken prior to onset of labour (96, 96%). The results of this study helps define the standards of consent Irish patients expect for epidural analgesia during labour.

    Full Text Available Inadvertent dural puncture during epidural anesthesia leads to intracranial hypotension, which if left unnoticed can cause life-threatening subdural hematomas or cerebellar tonsillar herniation. The highly variable presentation of intracranial hypotension hinders timely diagnosis and treatment. We present the case of a young laboring adult female, who developed subdural hygromas and a subdural hematoma following unintentional dural puncture during initiation of epidural anesthesia.

    Retrospectively study.The purpose of this study was to compare the effects of intraoperative epidural steroids and single dose intravenous steroids following a percutaneous endoscopic lumbar discectomy (PELD).Inflammatory irritation of dorsal root ganglia or sensory nerve roots may cause postoperative pain. Epidural steroids have been applied after a lumbar discectomy for more than 20 years. Epidural steroid application after a PELD is easier to perform and safer because the operations are under observation of the scope.We retrospectively reviewed the medical records of patients with lumbar intervertebral disc herniation who had undergone transforaminal PELD at our department. There are 60 patients in epidural steroid group, intravenous steroid group, and control group, respectively. Visual analog scores (VAS) and the Oswestry Disability Index (ODI) were collected. Successful pain control is defined as 50% or more reduction in back and leg pain (VAS scores).VAS scores (back and leg) and ODI showed a significant decrease in all groups when comparing pre- and postoperatively. Epidural steroid group had a significant improvement in successful pain control compared with the control group at 2 weeks of follow-up. VAS scores (leg) in the epidural steroid group showed a significant decrease compared with the intravenous steroids group at 1, 3, and 7 days after the surgery, but this difference had no statistical significance at 1, 6, and 12 months of follow-up. All groups did not show a significant difference in ODI at 1, 6, and 12 months follow-up.Epidural application of steroid has a better effect on controlling the postoperative pain of PELD in the short term. The epidural application of steroid did not show a tendency to cause infection.

    Full Text Available Objective: In our study, we aimed to compare epidural morphine and fentanyl analgesia and the side effects in post-thoracotomy pain management. Material and Methods: Forty patients, planned for elective thoracotomy were included. Bupivacain- morphine was administered through an epidural catheter to the patients in Group-M while bupivacain-fentanyl was given in Group-F. Pain assessment was carried out with the Visual Analogue Scale (VAS and VAS-I and VAS-II were assessed in 0, 4, 16 and 24th hour in the postoperative unit. Adverse effects were recorded after the 24th hour. Statistical analyses were performed by using Two-sample independent-t test, Mann Whitney-U test, Wilcoxon-signed ranks test and Pearson chi-squared tests. Results: Although, the VAS-I and VAS-II scores were lower in Group-M than Group-F, the difference was not significant statistically (p>0.05. When other hours were compared with initial states, beginning from the 4th hour, in both groups there was a statistically significant drop in VAS-I and VAS-II scores at all times (p<0.001. Comparing the complications between the groups, in Group-M nausea-vomiting (p<0.015 and bradycardia (p<0.012 were found significantly more frequently than in Group-F. Conclusion: We concluded that, in pain management after thoracic surgery, either morphine or fentanyl may be chosen in thoracal epidural analgesia but, especially in the early postoperative hours, close follow-up is necessary due to the risk of bradycardia development.

    The safety of ketamine when administered by the spinal route must be confirmed in various animal species before it is approved for use in humans. This study evaluates the ultrastructure of canine meninges after repeated doses of epidural S(+)-ketamine. Five dogs received S(+)-ketamine 5%, 1 mg/kg, twice a day for 10 days through an epidural catheter with its tip located at the L5 level. One dog received the same volume of normal saline at the same times. The spinal cord and meninges were processed for histopathological and ultrastructural studies. Clinical effects were assessed after each injection. Motor and sensory block appeared after each injection of S(+)-ketamine, but not in the dog receiving saline. No signs of clinical or neurologic alterations were observed. Using light microscopy, no meningeal layer showed alterations except focal infiltration at the catheter tip level by macrophages, lymphocytes, and a few mast cells. The cells of different layers were studied by electron microscopy and interpreted according to data from human and other animal species because no ultrastructural description of the canine meninges is currently available. There were no cellular signs of inflammation, phagocytosis, or degeneration in meningeal layers and no signs of atrophy, compression, or demyelinization in the areas of dorsal root ganglia and spinal cord around the arachnoid. These findings were common for dogs receiving S(+)-ketamine and the dog receiving saline. Repeated doses of epidural S(+)-ketamine 5%, 1 mg/kg, twice a day for 10 days was not associated to cellular alterations in canine meninges.

    The aim of our study was to determine if using the Epidrum to site epidurals improves success and reduces morbidity. Three hundred parturients requesting epidural analgesia for labour were enrolled. 150 subjects had their epidural sited using Epidrum and 150 using standard technique. We recorded subject demographics, operator experience, number of attempts, Accidental Dural Puncture rate, rate of failure to site epidural catheter, rate of failure of analgesia, Post Dural Puncture Headache and Epidural Blood Patch rates. Failure rate in Epidrum group was 9\\/150 (6%) vs 0 (0%) in the Control group (P = 0.003). There were four (2.66%) accidental dural punctures in the Epidrum group and none in the Control group (P = 0.060), and 2 epidurals out of 150 (1.33%) in Epidrum group were re-sited, versus 3\\/150 (2%) in the control group (P = 1.000). The results of our study do not suggest that using Epidrum improves success or reduces morbidity.

  20. Inadvertent injection of succinylcholine as an epidural test dose

    Chryssa Pourzitaki

    Full Text Available Abstract Background and objectives: Epidural action of neuromuscular blocking agents could be explained under the light of their physicochemical characteristics and epidural space properties. In the literature there are few cases of accidental neuromuscular agent's epidural administration, manifesting mainly with neuromuscular blockade institution or fasciculations. Case report: We report a case of accidental succinylcholine administration as an epidural test dose, in a female patient undergoing scheduled laparotomy, under combined general and epidural anesthesia. Approximately 2 min after the succinylcholine injection the patient complained for shortness of breath, while mild fasciculations appeared in her trunk and face, managed by immediate general anesthesia institution. With the exception of a relatively longer duration of neuromuscular blockade compared with intravenous administration, no neurological or cardiovascular sequelae or other symptoms of local or systemic toxicity were observed. Conclusions: Oral administration of diazepam seems to lessen the adverse effects from accidental epidural administration of succinylcholine. The meticulous and discriminative labeling of syringes, as well as keeping persistent cautions during all anesthesia procedures remains of crucial importance.

    Full Text Available Aims and Objectives: The risk assessment of epidural hematoma due to catheter placement in patients undergoing cardiac surgery is essential since its benefits have to be weighed against risks, such as the risk of paraplegia. We determined the risk of the catheter-related epidural hematoma in cardiac surgery based on the cases reported in the literature up to September 2012. Materials and Methods: We included all reported cases of epidural catheter placement for cardiac surgery in web and in literature from 1966 to September 2012. Risks of other medical and non-medical activities were retrieved from recent reviews or national statistical reports. Results: Based on our analysis the risk of catheter-related epidural hematoma is 1 in 5493 with a 95% confidence interval (CI of 1/970-1/31114. The risk of catheter-related epidural hematoma in cardiac surgery is similar to the risk in the general surgery population at 1 in 6,628 (95% CI 1/1,170-1/37,552. Conclusions: The present risk calculation does not justify not offering epidural analgesia as part of a multimodal analgesia protocol in cardiac surgery.

    Full Text Available Background: Alpha 2 -adrenergic agonists have synergistic action with local anesthetics and may prolong the duration of sensory, motor blockade and postoperative analgesia obtained with spinal anesthesia. Aim: The objectives of this study are to compare and evaluate the efficacy of intravenous dexmedetomidine premedication with clonidine and placebo on spinal blockade duration, postoperative analgesia and sedation in patients undergoing surgery under bupivacaine intrathecal block. Materials and Methods: In this prospective, randomized, double-blind placebo-controlled study, 75 patients of the American Society of Anesthesiologists status I or II, scheduled for orthopedic lower limb surgery under spinal anesthesia, were randomly allocated into three groups of 25 each. Group DE received dexmedetomidine 0.5 μgkg−1 , group CL received clonidine 1.0 μgkg−1 and placebo group PL received 10 ml of normal saline intravenously before subarachnoid anesthesia with 15 mg of 0.5% hyperbaric bupivacaine. Onset time and regression times of sensory and motor blockade, the maximum upper level of sensory blockade were recorded. Duration of postoperative analgesia and sedation scores along with side effects were also recorded. Data was analyzed using analysis of variance or Chi-square test, and the value of P < 0.05 was considered statistically significant. Results: The sensory block level was higher with dexmedetomidine (T4 ± 1 than clonidine (T6 ± 1 or placebo (T6 ± 2. Dexmedetomidine also increased the time (243.35 ± 56.82 min to first postoperative analgesic request compared with clonidine (190.93 ± 42.38 min, P < 0.0001 and placebo (140.75 ± 28.52 min, P < 0.0001. The maximum Ramsay sedation score was greater in the dexmedetomidine group than other two groups (P < 0.0001. Conclusion: Premedication with intravenous dexmedetomidine is better than intravenous clonidine to provide intraoperative sedation and postoperative analgesia during bupivacaine

    Objective: To evaluate the feasibility and clinical value of combined clonidine and sleep-deprivation induced seizures for ictal brain SPECT imaging in patients with epilepsy. Methods: Fifty-two epilepsy patients were given oral clonidine plus sleep-deprivation to induce seizures with video-electroencephalogram (VEEG) monitoring. Forty-seven patients were selected as control group, whose seizures were induced by sleep-deprivation only. 99 Tc m -ethylcysteinate dimer (ECD) was injected within 30 s since a clinical sign and/or a typical EEG discharge of epilepsy was recognized. Brain SPECT was performed 30 min after 99 Tc m -ECD injection. χ 2 -test was performed by using software SPSS 10.0. Results: One to two hr after oral intake of clonidine plus sleep-deprivation, 75% (39/52) patients were induced seizures, including 92.3% (36/39) with subclinical seizures and 7.7% (3/39) with clinical seizures. Ictal brain SPECT localized the lesions with high uptake of 99 Tc m -ECD in 37 (94.9%) patients. In control group, 38.3% (18/47) were induced epileptic seizures, including 77.8% (14/18) with subclinical seizures and 22.2% (4/18) with clinical seizures. The induction rate of epileptic seizures in clonidine plus sleep-deprivation group was significantly higher than that of control group (χ 2 = 13.614, P 2 = 1.253, P>0.05). Conclusions: The combination of oral intake of clonidine and sleep-deprivation could increase the induction rate of epileptic seizures and it is effective for epilepsy SPECT imaging. (authors)

    Epidural involvement is rarely associated with lymphoma, it being more typical of non-Hodgkin`s lymphoma in advanced stages of the disease. The invasion of the epidural space is usually caused by the extension of a paravertebral mass or by the affected vertebrae. However, the epidural space alone can be involved. We present a case of epidural lymphoma in a patient who presented with clinical evidence of spinal cord compression. Magnetic resonance disclosed the existence of an epidural mass compressing and displacing the spinal cord without involving the adjacent vertebra or the associated paravertebral mass.

    Full Text Available Purpose: The efficacy and safety of peribulbar anaesthesia was assessed using a combination of lidocaine, bupivacaine and clonidine during eye surgery. Methods: We prospectively studied 100 vitreo-retinal surgical procedures performed by several surgeons. The exclusion criteria included age below 30 years and, axial length of the orbit above 28 mm. Peribulbar was performed using Hamilton′s technique. A mixed anaesthetic solution of equal quantity of lidocaine 2% and bupivacaine 0.5% with clonidine (1mg/kg was injected. Patients received a mean volume of 14.5 ml ± 3.5 of the mixture. Akinesia and analgesia were assessed 15 minutes later by the surgeon. Whenever required, supplemental lidocaine 2% (3 ml by sub- Tenon infiltration was added by the surgeon. Supplemental injections were given only to patients who failed to develop analgesia. Results: The mean age of patients (male 52%, female 48% was 66 years ± 10 (mean ± SD, range 44-90. The 100 surgical procedures were made up of vitrectomy ± gas ± silicone oil (22/100, vitrectomy and lensectomy (6/100, vitrectomy and epiretinal membrane ± laser coagulation ± gas ± silicone oil (35/100, scleral buckling or encircling ± gas (36/100, and cryosurgery ± gas (1/100. Analgesia was adequate throughout surgery without any supplementation in 85% of cases and with a sub-Tenon infiltration in 99%. Akinesia was complete in 84%, mild in 12% and absent in 4% of cases. The sub-Tenon injection was performed in 15% of cases. Three patients (3% were agitated during surgery. No neurologic or cardiac complication was seen. In one patient, the systolic blood pressure decreased from 170 to 110 mmHg, 30 minutes after the institution of the peribulbar block. Conclusion: Our results show that peribulbar anaesthesia in the proposed mixture offers excellent analgesia in 85% of patients, and in 99% of the patients when supplemented by a subtenon injection. The current mixture of lidocaine, bupivacaine and

    Acute swelling of the parotid glands after general anesthesia has become known as anesthesia mumps. Its cause is unknown. Only one case of postsurgical parotitis without general anesthesia is reported. This report describes three cases in this setting after plastic surgery. A 37-year-old women underwent breast surgery and abdominoplasty with a dual thoracic/lumbar epidural block (bupivacaine 0.5 %). The operative time totaled almost 6 h. Subsequently, 4 h after surgery, the patient experienced painless bilateral parotid swelling without palpable crepitus. The edema resolved completely within 12 h under clinical observation and parenteral hydration. A 45-year-old patient received subglandular breast implants and body contouring with liposuction, all with the patient under a dual thoracic/lumbar epidural block with 0.5 % marcaine. The total surgical time was 5 h. Subsequently, 3 h after surgery, the patient experienced a similar clinical presentation. The problem resolved completely in 36 h with clinical observation and parenteral hydration. CASE 3: A 30-year-old patient received a subglandular breast implant and underwent liposuction of the outer thighs using a dual thoracic/lumbar epidural block with lidocaine 1 %. The duration of surgery was 1 h. Subsequently, 5 h postoperatively, the patient experienced a similar clinical presentation. Dexamethasone and parenteral hydration were administered. The problem resolved completely in 48 h without sequelae. The occurrence of parotitis in patients undergoing surgery under epidural anesthesia is a novel situation, which increases the range of possible etiologies for this little known condition. Dehydration leading to transient parotid secretion obstruction may play a significant role. Further reports of parotitis occurring in the regional anesthesia setting are expected to help elucidate its pathophysiology. This journal requires that authors assign a level of evidence to each article. For a full description of

    BACKGROUND: Clonidine used as an adjuvant to ropivacaine have been shown to prolong the duration of peripheral nerve blocks. The mechanism of action remains unclear. We hypothesized, that clonidine used as an adjuvant to ropivacaine extends the duration of an adductor canal block (ACB......) by a peripheral mechanism, compared to ropivacaine alone when controlling for systemic effects. METHODS: We conducted a paired, blinded, randomized trial in healthy volunteers. Participants received bilateral ACBs containing 20 ml ropivacaine 0.5% + 1 ml clonidine 150μg/ml in one leg and 20 ml ropivacaine 0...... pain detection threshold. RESULTS: We enrolled 21 volunteers and all completed the trial. There was no difference in duration of sensory block assessed with an alcohol swab: Mean duration in the leg receiving ropivacaine + clonidine was 19.4h (SD 2.7) compared to 19.3h (SD 2.4) in the leg receiving...

    clonidine would decrease brain edema, blood-brain barrier permeability, and glycocalyx disruption at 24 hours after trauma. METHODS: We subjected 53 adult male Sprague-Dawley rats to lateral fluid percussion brain injury and randomized infusion with propranolol (n = 16), propranolol + clonidine (n = 16......), vehicle (n = 16), or sham (n = 5) for 24 hours. Primary outcome was brain water content at 24 hours. Secondary outcomes were blood-brain barrier permeability and plasma levels of syndecan-1 (glycocalyx disruption), cell damage (histone-complexed DNA fragments), epinephrine, norepinephrine, and animal.......555). We found no effect of propranolol and propranolol/clonidine on blood-brain barrier permeability and animal motor scores. Unexpectedly, propranolol and propranolol/clonidine caused an increase in epinephrine and syndecan-1 levels. CONCLUSION: This study does not provide any support for unselective...

    The purpose of this study is to analyze whether supplementation of general anesthesia (GA) with thoracic epidural analgesia (TEA) for right lobe donor hepatectomy is a safe modality of pain relief in terms of changes in postoperative coagulation profile, incidence of epidural catheter-related complications, and timing of removal of epidural catheter. Retrospective analysis of the record of 104 patients who received TEA for right lobe donor hepatectomy was done. Platelet count, international normalized ratio, alanine aminotransferase, and aspartate aminotransferase were recorded postoperatively until the removal of the epidural catheter. The day of removal of the epidural catheter and visual analogue scale (VAS) scores were also recorded. Any complication encountered was documented. Intraoperatively, central venous pressure (CVP), hemodynamic variables, and volume of intravenous fluids infused were also noted. Statistical analysis was performed by using SPSS statistical package, version 17.0 (SPSS Inc. Chicago, IL). Continuous variables were presented as mean ± standard deviation. A total of 90% of patients had mean VAS scores between 1 and 4 in the postoperative period between days 1 and 5. None of the patients had a VAS score above 5. Although changes in coagulation status were encountered in all patients in the postoperative period, these changes were transient and did not persist beyond postoperative day (POD) 5. There was no delay in removal of the epidural catheter, and the majority of patients had the catheter removed by POD 4. There was no incidence of epidural hematoma. Aside from good intraoperative and postoperative analgesia, TEA in combination with balanced GA and fluid restriction enabled maintenance of low CVP and prevention of hepatic congestion. In conclusion, vigilant use of TEA appears to be safe during donor hepatectomy. Living liver donors should not be denied efficient analgesia for the fear of complications.

    A case of spinal epidural hematoma diagnosed by CT scan is reported. A 58-year-old man was admitted on June 18, 1984. He had had a sudden onset of severe low-back pain 7 days before admission and had developed paraparesis and numbness of the lower limbs 4 day before admission. Physical examination revealed weakness in the lower limbs, with the reflexes there decreased. The Babinski reflex and the Chaddock reflex were, however, present on both sides. Sensory disturbances were noted below L 2 . Urinary incontinence was present, too. Metrizamide myelography revealed an epidural mass which was located from the power part of T 11 to the upper part of L 2 . A CT scan revealed a biconvex, relatively high-density mass in the posterior spinal canal. On the day of admission, a laminectomy was performed from T 11 to L 1 , and the epidural hematoma was evacuated. The postoperative course was uneventful. Spinal epidural hematoma is uncommon. A CT scan can be used for an early diagnosis of this lesion. According to the review of the CT findings in 15 reported cases, including our case, CT reveals a smoothly marginated biconvex homogeneous density mass. The density of the hematoma decreases with the time. An acute type (within 3 days) is high-density, while a chronic type has a relatively high or isodensity. The acute type is easily differentiated from other epidural masses, such as a herniated disc, an epidural abscess, and an epidural tumor. On the other hand, the diagnosis of the chronic type is not always easy. (author)

    1. The antinociceptive action of clonidine (Clon) and the interactions with alpha 1, alpha 2 adrenoceptor and opioid receptor antagonists was evaluated in mice by use of chemical algesiometric test (acetic acid writhing test). 2. Clon produced a dose-dependent antinociceptive action and the ED50 for intracerebroventricular (i.c.v.) was lower than for intraperitoneal (i.p.) administration (1 ng kg-1 vs 300 ng kg-1). The parallelism of the dose-response curves indicates activation of a common receptor subtype. 3. Systemic administration of prazosin and terazosin displayed antinociceptive activity. Pretreatment with prazosin produced a dual action: i.c.v. Clon effect did not change, and i.p. Clon effect was enhanced. Yohimbine i.c.v. or i.p. did not induce antinonciception, but antagonized Clon-induced activity. These results suggest that alpha 1- and alpha 2-adrenoceptors, either located at the pre- and/or post-synaptic level, are involved in the control of spinal antinociception. 4. Naloxone (NX) and naltrexone (NTX) induced antinociceptive effects at low doses (microgram kg-1 range) and a lower antinociceptive effect at higher doses (mg kg-1 range). Low doses of NX or NTX antagonized Clon antinociception, possibly in relation to a preferential mu opioid receptor antagonism. In contrast, high doses of NX or NTX increased the antinociceptive activity of Clon, which could be due to an enhanced inhibition of the release of substance P. 5. The results obtained in the present work suggest the involvement of alpha 1-, alpha 2-adrenoceptor and opioid receptors in the modulation of the antinociceptive activity of clonidine, which seems to be exerted either at spinal and/or supraspinal level.

    Full Text Available Background Deliberate hypotension is one way to achieve a bloodless surgical field in endoscopic sinus surgery (ESS. We compared two anaesthesia regimens to induce deliberate hypotension and attempted to determine the most efficient one. Methods Fifty-nine patients undergoing ESS were minimized into two groups. In the CLO group, patients received I.V. sufentanil 0.15 µg/kg together with I.V. clonidine 2–3 µg/kg. In the REMI group, patients received remifentanil at a rate of up to 1 µg/kg/min. Fromme scores were collected 15 min after the incision and at the end of the procedure. Mean arterial pressure readings (MAP, heart rate readings, time to eyes opening, time to extubation, pain scores, analgesic requirements, and oxygen needs were collected and compared. Results There were no significant differences in Fromme scores between the two groups. The averaged MAP from 15 min to the end of the procedure was significantly lower in the REMI group; these patients also received more ephedrine. Significantly fewer patients in the CLO group needed oxygen therapy to keep their Pulse Oximeter Oxygen Saturation within 3% of their preoperative values. Patients in this group also needed less piritramide in the recovery room, and their pain scores were lower at discharge from the recovery room. Discussion Although both anaesthesia regimens offered a similar quality of surgical field, this study suggests that clonidine had a better average safety profile. Furthermore, patients who received this regimen required fewer painkillers immediately after surgery.

    Full Text Available A 74 year-old patient with a nocturnal onset of neck and chest pain was brought to an emergency clinic. Physical examination and cardiac assessment were normal. Three hours after the addmittance, a flaccid paralysis of the four limbs supervened. Suspecting of an unusual onset of central nervous system infection, a lumbar puncture was performed, yielding 20 ml of normal cerebrospinal fluid. Thirty oinutes after the puncture, the patient completely regained neurological funcion. He was then referred to a General Hospital where a computed tomography (CT scan was done showing a large cervical epidural bleeding in the posterolateral region of C4/C5 extending to C7/Th1, along with a C6 vertebral body hemangioma. A magnetic resonance imaging revealed the same CT findings. A normal selective angiography of vertebral arteries, carotid arteries and thyreocervical trunk was carried out. Spontaneous spinal epidural hematoma (ASSEH is a rare but dramatic cause of neurological impairment. In this article we report a fortunate case of complete recovery after an unusual spine cord decompression. We also review the current literature concerning diagnosis and treatment of ASSEH.Paciente de 74 anos acordou à noite sentindo fortes dores na região da nuca acompanhadas de ansiedade e desconforto torácico e respiratório.

    CT revealed the presence of epidural emphysema as an incidental finding in a 13-year-old boy in whom mild infrequent coughing during an asthmatic attack resulted in a pneumomediastinum and subcutaneous emphysema. Epidural emphysema was not associated with neurological symptoms. The CT images demonstrated the pathway of air leakage from the posterior mediastinum through the intervertebral foramina into the epidural space. Repeat CT showed spontaneous resolution of the epidural emphysema. (orig.) With 2 figs., 9 refs.

    Full Text Available Background. The study presents the experience with epidural analgesia (EPA for pain relief in Izola General Hospital from 2003 to 2006, the differences of labour between epidural analgesia and without it and the parturients’ satisfaction. Methods. A retrospective observational study was performed. Data were compared between 214 parturients with EPA matched by 214 parturients without. The control parturient was the equiipara with a term birth and the cephalic presentation of fetus that delivered just before the parturient of the EPA group. Maternal age, labor length, rate of oxitocin use, instrumental deliveries and cesarean sections, Apgar scores and birthweights were compared. The questionnaire was used to estimate the pain in 62 parturients. Results. In GH Izola in 214 parturients (10 % EPA was applied for labour pain relief in the period from July 2003 till December 2006. In the EPA group there was a statistically significance compared with the control group: higher parturients’ mean age (30.5 vs 28.7 y.o.; p < 0.0005, longer labour length (278 vs 222 min; p < 0.0005, higher oxitocin use rate (93.4 % vs 72.9 %; p < 0.0001 and higher instrumental delivery rate (vacuum extraction 14 % vs 1.9 %; p < 0.0001. The cesarean section rates were equal in both groups. Despite the higher instrumental delivery rate and the longer labour length in the EPA group there were no worse perinatal outcomes, neither was statisticaly significant difference in Apgar scores compared with the control group. The mean intensity of pain was highest before the EPA application (VAS 7, lowest during the transition stage (VAS 1.5 and some higher during the second phase (VAS 2.7. Most of parturients in the EPA group were satisfied; 92 % of them evaluated the EPA as good or very good. Conclusions. EPA is a very effective method for pain control during labor. The parturients’ satisfaction with this pain control method is appropriate. Despite the higher instrumental

    We evaluated the systemic and local effects of clonidine as an analgesic adjunct to psoas compartment block (PCB) with levobupivacaine. In a randomized, prospective, double-blind trial, 36 patients requiring hip fracture surgery received PCB and general anesthesia. Patients were randomized into three groups. Each patient received PCB with 0.4 mL\\/kg of levobupivacaine 0.5%. The control group (group L) received IV saline, the systemic clonidine group (group IC) received IV clonidine 1 mug\\/kg, and the peripheral clonidine group (group C) received IV saline and PCB with clonidine 1 microg\\/kg. The interval from time of completion of block injection to first supplementary analgesic administration was longer in group IC compared with group L (mean +\\/- sd, 13.4 +\\/- 6.1 versus 7.3 +\\/- 3.6 h; P = 0.03). There was no difference between group C and group L (10.3 +\\/- 5.9 versus 7.3 +\\/- 3.6 h; P > 0.05). The groups were similar in terms of 24 h cumulative morphine and acetaminophen consumption. There were no significant differences among groups regarding postoperative adverse effects (bradycardia, hypotension, sedation, and nausea). We conclude that IV but not perineural clonidine (1 microg\\/kg) prolongs analgesia after PCB without increasing the incidence of adverse effects.

    Spinal epidural extramedullary haematopoiesis is very rare in thalassaemia. A 27-year-old man with thalassaemia intermedia presented with symptoms and signs of spinal cord compression. MRI showed a thoracic spinal epidural mass, representing extramedullary haematopoietic tissue, compressing the spinal cord. Following radiotherapy, serial MRI revealed regression of the epidural mass and gradual resolution of spinal cord oedema. (orig.)

    To examine epidural fat images, lumbar magnetic resonance (MR) images were retrospectively reviewed in a total of 103 patients with surgically proven lumbar disc herniation (DH, n=57) and lumbar canal stenosis (LCS, n=46). Epidural fat images consisted of middorsal epidural fat (MDF), paramedian ventral fat (PVF) and intervertebral foraminal fat (IFF) ones. In the group of DH, the thickness of MDF image did not correlate with that of subcutaneous fat, suggesting that epidural fat was not affected by body fat. From the pathophysiological point of view, decrease and disappearance of MDF images correlated with compression of the epidural canal. Decrease and disappearance of PVF images lead to suspicious compression of the traversing root. In addition, asymmetrical PVF images were useful for the bilateral diagnosis of herniation. Abnormal findings of IFF images were suggestive of compression of the exiting nerve root at the intervertebral foramen. This was also seen frequently at the non-responsible level in patients over the age of 50. Degenerative and sequentrated spondylolistheses in the group of LCS were more frequently associated with a higher incidence of abnormal findings of IFF images, suggesting the presence of existing nerve root compression.

    Purpose: Spinal epidural hematoma (SEH) is a rare clinical entity with a bleak outcome. The aim of our study was to establish the value of MR findings in the diagnosis of nontraumatic SEH. Material and Methods: Seven patients with nontraumatic SEH were examined by MR at 1.5 T. Two patients were under anticoagulation therapy with heparin, and 2 others were taking salicylic acid. One patient had lupus erythematodes with a marked thrombocytopenia. One patient had a spinal arteriovenous malformation. Results: MR imaging permitted the accurate localization of extradural intraspinal expansive lesions which exhibited the characteristic signal intensities of blood. Five patients underwent laminectomy and evacuation of the hematoma. In the acute phase, the hematomas appeared isointense when compared with the spinal cord on T1-weighted images and hyperintense on T2-weighted images. Later the hematomas were hyperintense on T1-weighted images and showed signals identical to those of cerebrospinal fluid (CSF) on T2-weighted images. Conclusion: MR imaging established the exact diagnosis and localization of SEH in all cases. MR also can provide useful information about the age of the hematomas. (orig.)

    Epidural cortical stimulation (ECS) is a developing therapy to treat neurological disorders. However, it is not clear how the cortical anatomy or the polarity and position of the electrode affects current flow and neural activation in the cortex. We developed a 3D computational model simulating ECS over the precentral gyrus. With the electrode placed directly above the gyrus, about half of the stimulus current flowed through the crown of the gyrus while current density was low along the banks deep in the sulci. Beneath the electrode, neurons oriented perpendicular to the cortical surface were depolarized by anodic stimulation, and neurons oriented parallel to the boundary were depolarized by cathodic stimulation. Activation was localized to the crown of the gyrus, and neurons on the banks deep in the sulci were not polarized. During regulated voltage stimulation, the magnitude of the activating function was inversely proportional to the thickness of the CSF and dura. During regulated current stimulation, the activating function was not sensitive to the thickness of the dura but was slightly more sensitive than during regulated voltage stimulation to the thickness of the CSF. Varying the width of the gyrus and the position of the electrode altered the distribution of the activating function due to changes in the orientation of the neurons beneath the electrode. Bipolar stimulation, although often used in clinical practice, reduced spatial selectivity as well as selectivity for neuron orientation.

I appreciate the author’s exhaustive search of literature and discussion with some limitation on review basics like methodology, which may affect the reliability of the review findings. The effects of risk factors for anastomosis leak, such as malnutrition, smoking, steroid use, bowel preparation, chemotherapy, duration of surgery, use of pressors, intravenous fluid administration, blood transfusion, and surgical anastomotic technique, were well discussed.1 However, from anesthesia perspective, there are some other well-studied risk factors that can affect healing of anastomosis wound and cause anastomosis leak. Among others, the effect of neostigmine and epidural block has been reported in many studies since half a century ago. View the original paper by Phillips

    Extraskeletal ewing sarcoma is a rare malignant tumor found in children and young adults. It commonly occurs in deep soft tissue of the trunk, especially in the paravertebral region and extremities. We report two cases of extraskeletal ewing sarcoma occurring as a cervical epidural tumor in elderly patients. The MRI and CT findings showed that paravertebral epidural tumors had invaded the spinal canal through the intervertebral foramen. At T1-weighted MR imaging, the masses were isointense to muscle, and at T2* and T2-weighted images were hyperintense, and heterogeneous contrast enhancement was observed. Extraskeletal ewing sarcoma, though quite rare, should be borne in mind in the differential diagnosis of paraspinal epidural tumors.

    2004-01-01

    Lumbosacral epidural lipomatosis (LEL) has been defined as a disease produced by excessive fat deposition within the spinal canal. In the pre MRI-era, this entity has been commonly overlooked. While a mild (or moderate) epidural fat hypertrophy is basically asymptomatic, severe LEL represents the symptomatic end-stage of this disease, conducing in many cases to surgical fat debulking. Since LEL may be concurrent with other substantial spinal abnormalities (e.g. disk herniation) MRI exams may increase our awareness of this condition to avoid its underestimation. MRI enables a reliable LEL characterization and may show its eventual reversibility in obese or corticosteroid receiving patients. This pictorial essay illustrates the usefulness of MRI to demonstrate the ongoing process of epidural fat accumulation in mild, moderate and severe LEL. The different morphologic patterns of the thecal sac produced by advanced LEL are analyzed. LEL and concurrent spinal disorders with superimposed neurological symptoms and signs are illustrated.

    2017-09-01

    Full Text Available The anterior cingulate cortex (ACC is an important brain area for the regulation of neuropathic pain. The α2A adrenoceptor is a good target for pain management. However, the role of cingulate α2A adrenoceptors in the regulation of neuropathic pain has been less studied. In this study, we investigated the involvement of cingulate α2A adrenoceptors in the regulation of neuropathic pain at different time points after peripheral nerve injury in mice. The application of clonidine, either systemically (0.5 mg/kg intraperitoneally or specifically to the ACC, increased paw withdrawal thresholds (PWTs and induced conditioned place preference (CPP at day 7 after nerve injury, suggesting that cingulate α2 adrenoceptors are involved in the regulation of pain-like behaviors. Quantitative real-time PCR data showed that α2A adrenoceptors are the dominant α2 adrenoceptors in the ACC. Furthermore, the expression of cingulate α2A adrenoceptors was increased at day 3 and day 7 after nerve injury, but decreased at day 14, while no change was detected in the concentration of adrenaline or noradrenaline. BRL-44408 maleate, a selective antagonist of α2A adrenoceptors, was microinfused into the ACC. This blocking of cingulate α2A adrenoceptors activity abolished the CPP induced by clonidine (0.5 mg/kg intraperitoneally but not the effects on PWTs at day 7. However, clonidine applied systemically or specifically to the ACC at day 14 increased the PWTs but failed to induce CPP; this negative effect was reversed by the overexpression of cingulate α2A adrenoceptors. These results suggest that cingulate α2A adrenoceptors are necessary for the analgesic effects of clonidine on spontaneous pain.

    Full Text Available We investigated the influence of morphine and ketamine or clonidine in mice on the expression of genes that may mediate pronociceptive opioid effects.C57BL/6 mice received morphine injections thrice daily using increasing doses (5-20 mg∙kg(-1 for 3 days (sub-acute, n=6 or 14 days (chronic, n=6 and additionally either s-ketamine (5 mg∙kg(-1, n=6 or clonidine (0.1 mg∙kg(-1, n=6. Tail flick test and the assessment of the mechanical withdrawal threshold of the hindpaw was performed during and 4 days after cessation of opioid treatment. Upon completion of the behavioural testing the mRNA-concentration of the NMDA receptor (NMDAR1 and β-arrestin 2 (Arrb2 were measured by PCR.Chronic opioid treatment resulted in a delay of the tail flick latency with a rapid on- and offset. Simultaneously the mice developed a static mechanical hyperalgesia with a delayed onset that that outlasted the morphine treatment. Sub-acute morphine administration resulted in a decrease of NMDAR1 and Arrb2 whereas during longer opioid treatment the expression NMDAR1 and Arrb2 mRNA increased again to baseline values. Coadministration of s-ketamine or clonidine resulted in a reversal of the mechanical hyperalgesia and inhibited the normalization of NMDAR1 mRNA expression but had no effect on the expression of Arrb2 mRNA.In the model of chronic morphine therapy the antinociceptive effects of morphine are represented by the thermal analgesia while the proniceptive effects are represented by the mechanical hyperalgesia. The results indicate that the regulation of the expression of NMDAR1 and Arrb2 may be associated to the development of OIH in mice.The results indicate that co-administration of clonidine or ketamine may influence the underlying mechanisms of OIH.

    Full Text Available In order To investigate the effect of addition of clonidine to lidocaine on duration of spinal analgesia and need for postoperative analgesics after Caesarean section delivery, this randomized case-controlled double-blind clinical trial was designed and conducted. 166 eligible women were randomly allocated to either case or control group (n=83, Spinal anesthesia was done by 75-100 mg lidocaine 0.5% in control group and by 75-100 mg lidocaine 0.5% plus 75µg clonidine in case group. Onset of analgesia, Blood pressure, Hypotension, Bradycardia, and Neonates Apgar scores were recorded during surgery. After surgery, duration of sensory and motor functions, Intensity of post-operative nausea and vomiting, Total analgesic consumption and time to first analgesic request were assessed. Data were analyzed by SPSS and an alpha level < 0.05 was considered to be statistically significant. Onset of analgesia, Duration of Motor and sensory block, mothers’ systolic blood pressure and pulse rate in different recorded times, and Total Analgesic consumption in case group showed a statically significant difference in comparison to the control group. Analgesia demanding, Time of first request for analgesics, Intensity of Nauseas and vomiting, Apgar score showed no significant difference. We have demonstrated that addition of 75 µg clonidine to lidocaine extends spinal analgesia along with sensory and motor block after Caesarean section and improves early analgesia without clinically significant maternal or neonatal side-effects. This single 75 µg intrathecal clonidine dose also reduced the amount of subsequent analgesic consumption during the first 12 hours after delivery.

    Full Text Available Continuous epidural blockade remains the cornerstone of pediatric regional anesthesia. However, the risk of catastrophic trauma to the spinal cord when inserting direct thoracic and high lumbar epidural needles in anesthetized or heavily sedated pediatric patients is a concern. To reduce this risk, research has focused on low lumbar or caudal blocks (ie, avoiding the spinal cord and threading catheters from distal puncture sites in a cephalad direction. However, with conventional epidural techniques, including loss-of-resistance for localization of the needle, optimal catheter tip placement is difficult to assess because considerable distances are required during threading. Novel approaches include electrical epidural stimulation for physiological confirmation and segmental localization of epidural catheters, and ultrasound guidance for assessing related neuroanatomy and real-time observation of the needle puncture and, potentially, catheter advancement. The present article provides a brief and focused review of these two advances, and outlines recent clinical experiences relevant to pediatric epidural anesthesia.

    Epidural involvement is rarely associated with lymphoma, it being more typical of non-Hodgkin's lymphoma in advanced stages of the disease. The invasion of the epidural space is usually caused by the extension of a paravertebral mass or by the affected vertebrae. However, the epidural space alone can be involved. We present a case of epidural lymphoma in a patient who presented with clinical evidence of spinal cord compression. Magnetic resonance disclosed the existence of an epidural mass compressing and displacing the spinal cord without involving the adjacent vertebra or the associated paravertebral mass.

    Development of collateral circulation belongs among the typical signs of aortic coarctation. Cerebral or spinal artery aneurysm formation with increased risk of subarachnoid hemorrhage represent the most common neurovascular complication of this disease. We report a case of a 20-year-old sportsman who developed acute non-traumatic paraplegia as a result of extensive spinal epidural hemorrhage from collateral vessels accompanying aortic coarctation which was unrecognized up to that time. To the best of our knowledge, acute spinal epidural hematoma as a complication of aortic coarctation has not been previously reported. (orig.)

    Full Text Available Acute epidural hematoma is a critical emergency all around the world, and its aggressive diagnosis and treatment are of vital importance. Emergent surgical evacuation of the hematoma is known as standard management; however, conservative procedures are also used for small ones. Spontaneous rapid resolution of these hematomas has also been reported in eight pediatric cases. Various theories have been proposed to explain the underlying pathophysiology of this resolution. Herein, we are reporting a new pediatric case with spontaneously resolving acute epidural hematoma 12 hours after admission to the emergency room.

    Development of collateral circulation belongs among the typical signs of aortic coarctation. Cerebral or spinal artery aneurysm formation with increased risk of subarachnoid hemorrhage represent the most common neurovascular complication of this disease. We report a case of a 20-year-old sportsman who developed acute non-traumatic paraplegia as a result of extensive spinal epidural hemorrhage from collateral vessels accompanying aortic coarctation which was unrecognized up to that time. To the best of our knowledge, acute spinal epidural hematoma as a complication of aortic coarctation has not been previously reported. (orig.)

    Although bone infarction is a common feature in sickle cell disease, the involvement of the orbit is an unusual complication. Intracranial bleeding is another uncommon and serious complication. Few cases of orbital infarction alone have been reported. We report imaging findings (CT, bone scan, MRI) in a 16-year-old boy with sickle cell disease with orbital infarction and epidural hematoma. The precise cause of epidural hematoma is not well known, but it is probably related to vaso-occlusive episodes and the tearing of small vessels. (orig.)

    Full Text Available This is a rare case of persistent Horner′s syndrome following epidural anesthesia and Caesarean section. A 33-year-old female presented with persistent ptosis and miosis following epidural anesthesia and Caesarian section several months prior. Magnetic resonance imaging (MRI/magnetic resonance angiography (MRA of head, neck, and chest were unremarkable. Medline search using terms Horner′s, epidural, spinal anesthesia, delivery, childbirth, Caesarian, and pregnancy identified 31 articles describing Horner′s syndrome in obstetric epidural anesthesia, of which 11 were following Caesarean section. The increased incidence of Horner′s syndrome in the setting of epidural anesthesia in pregnancy may be related to epidural venous engorgement and cephalic spread of the local anaesthetic, with disruption in the oculosympathetic pathway. It is important to include recent epidural anesthesia within the differential diagnosis of acute Horner′s syndrome in a postpartum female. Rarely, the ptosis may be permanent and require surgical intervention.

    To compare the running-drip and hanging-drop techniques for locating the epidural space in dogs. Prospective, randomized, clinical trial. Forty-five healthy dogs requiring epidural anaesthesia. Dogs were randomized into four groups and administered epidural anaesthesia in sternal (S) or lateral (L) recumbency. All blocks were performed by the same person using Tuohy needles with either a fluid-prefilled hub (HDo) or connected to a drip set attached to a fluid bag elevated 60 cm (RDi). The number of attempts, 'pop' sensation, clear drop aspiration or fluid dripping, time to locate the epidural space (TTLES) and presence of cerebrospinal fluid (CSF) were recorded. A morphine-bupivacaine combination was injected after positive identification. The success of the block was assessed by experienced observers based on perioperative usage of rescue analgesia. Data were checked for normality. Binomial variables were analysed with the chi-squared or Fisher's exact test as appropriate. Non-parametric data were analysed using Kruskal-Wallis and Mann-Whitney tests. Normal data were studied with an anova followed by a Tukey's means comparison for groups of the same size. A p-value of Drop aspiration was observed more often in SHDo (nine of 11 dogs) than in LHDo (two of 11 dogs) (p = 0.045). Mean (range) TTLES was longer in LHDo [47 (18-82) seconds] than in SHDo [20 (14-79) seconds] (p = 0.006) and SRDi [(34 (17-53) seconds] (p = 0.038). There were no differences in 'pop' sensation, presence of CSF, rescue analgesia or pain scores between the groups. The running-drip method is a useful and fast alternative technique for identifying the epidural space in dogs. The hanging-drop technique in lateral recumbency was more difficult to perform than the other methods, requiring more time and attempts.

    2013-01-01

    Full Text Available Background: Ropivacaine is a newer local anesthetic, proven to have a better safety margin than bupivacaine and lignocaine. While maintaining this advantage and improving the intraoperative quality of anesthesia, the use of analgesic adjuvants has been proven to be valuable. Aim: To compare the efficacy of clonidine and fentanyl as adjuvants to intrathecal isobaric ropivacaine for major lower limb surgeries. Settings and Designs: Randomized double-blind control trial. Materials and Methods: Seventy patients were randomly divided in two groups. Ropivacaine-Clonidine group (RC received 60 mcg of clonidine with 15 mg of 0.5% isobaric ropivacaine, Ropivacaine Fentanyl group (RF received 25 mcg of fentanyl with 15 mg of 0.5% isobaric ropivacaine intrathecally. The onset and duration of sensory-motor block were recorded. The total analgesia time, sedation score, hemodynamic parameters, and side-effects were noted. Statistical Analysis: SPSS statistical package was used for statistical analysis. Paired and unpaired t-test, analysis of variance and chi-square test were used for statistical calculation. Result: The duration of sensory block in RC (329.42 ± 33.86, RF (226 ± 46.98, and motor block in RC (248.51 ± 55, RF (212.60 ± 43.52 out lasted the duration of surgery (125.61 + 64.46. In clonidine group, there was significant prolongation of sensory block (P < 0.001, motor block (P < 0.01 and the total analgesia time (P < 0.001. Hypotension and bradycardia occurred in 8.6% patients in clonidine group, whereas pruritus was experienced by 8.6% patients in fentanyl group. Conclusion: Ropivacaine when combined with clonidine or fentanyl provided adequate subarachnoid block for major surgeries, wherein clonidine has advantage over fentanyl as it increased the duration of subarachnoid block and prolonged the postoperative analgesia.

    Full Text Available Hai Meng, Qi Fei, Bingqiang Wang, Yong Yang, Dong Li, Jinjun Li, Nan Su Department of Orthopedics, Beijing Friendship Hospital, Capital Medical University, Beijing, People’s Republic of China Background: Epidural injections of anesthetic with or without steroids are widely used for treating lumbar spinal stenosis, a common cause of chronic low back pain, but there is a lack of rigorous data comparing the effectiveness of epidural injections of anesthetic with and without steroids. This meta-analysis presents a current, comprehensive picture of how epidural injections of anesthetic with steroids compare with those using local anesthetic alone.Methods: PubMed, Embase, Web of Science, and Cochrane Library databases were searched from their inception through February 5, 2015. Weight mean difference, risk ratio, and 95% confidence intervals were calculated. A random effects model or fixed effects model was used to pool the estimates, according to the heterogeneity between the included studies.Results: We included 13 randomized controlled trials, involving 1,465 patients. Significant pain relief (≥50% was demonstrated in 53.7% of patients administered with epidural injections of anesthetic with steroids (group 1 and in 56.4% of those administered with local anesthetic alone (group 2. Patients showed a reduction in numeric rating scale pain score of 3.7 and 3.6 in the two groups, respectively. Significant functional improvement was achieved in 65.2% of patients in group 1 and 63.1% of patients in group 2, with Oswestry Disability Index reductions of 13.8 and 14.5 points, respectively. The overall number of injections per year was 3.2±1.3 and 3.4±1.2 with average total relief per year of 29.3±19.7 and 33.8±19.3 weeks, respectively. The opioid intakes decreased from baseline by 12.4 and 7.8 mg, respectively. Among the outcomes listed, only total relief time differed significantly between the two groups.Conclusion: Both epidural injections with

    Spondylodiscitis caused by Aggregatibacter aphrophilus, formerly known as Haemophilus paraphrophilus, is an unusual condition and can be very difficult to diagnose. We report a case of cervical spondylodiscitis complicated by spinal epidural abscess in a 63-year-old woman, without underlying predisposing conditions. The source of infection was identified as a periodontal infection. The patient was successfully treated with systemic antibiotics.

  13. Spontaneous Cervical Epidural Hematoma with Hemiparesis Mimicking Cerebral Stroke

    Full Text Available Aim. Spontaneous cervical epidural hematoma (SCEH is defined as an epidural hematoma that does not have an etiological explanation. The most common site for SCEH is cervicothoracic area. Early diagnosis and treatment are important for prognosis and good results. In this paper, we aimed to present a case who complains of sudden weakness on right extremities imitating cerebral stroke and that neuroimaging reveals spontaneous cervical epidural hematoma. Case. A 72-year-old woman was admitted to our hospital with acute neck pain and loss of strength on right extremities. On neurological examination, the patient had right hemiparesis. PT, aPTT, and INR results were 50.5, 42.8, and 4.8, respectively. Cranial MRI was in normal limits. Spinal MRI revealed a lesion that extends from C4 to C7 located on the right side and compatible with epidural hematoma. The patient was operated after normalization of INR values. Conclusion. Even though SCEH is a rare condition, it can cause severe morbidity and mortality. Early diagnosis and treatment are quiet important for prognosis. SCEH can easily be mistaken for stroke as with other pathologies and this diagnosis should come to mind especially in patients who have diathesis of bleeding.

    Full Text Available Background and Objective. Although minimally invasive surgical treatment of acute epidural hematoma attracts increasing attention, no generalized indications for the surgery have been adopted. This study aimed to evaluate the effects of minimally invasive surgery in acute epidural hematoma with various hematoma volumes. Methods. Minimally invasive puncture and aspiration surgery were performed in 59 cases of acute epidural hematoma with various hematoma volumes (13–145 mL; postoperative follow-up was 3 months. Clinical data, including surgical trauma, surgery time, complications, and outcome of hematoma drainage, recovery, and Barthel index scores, were assessed, as well as treatment outcome. Results. Surgical trauma was minimal and surgery time was short (10–20 minutes; no anesthesia accidents or surgical complications occurred. Two patients died. Drainage was completed within 7 days in the remaining 57 cases. Barthel index scores of ADL were ≤40 (n=1, 41–60 (n=1, and >60 (n=55; scores of 100 were obtained in 48 cases, with no dysfunctions. Conclusion. Satisfactory results can be achieved with minimally invasive surgery in treating acute epidural hematoma with hematoma volumes ranging from 13 to 145 mL. For patients with hematoma volume >50 mL and even cerebral herniation, flexible application of minimally invasive surgery would help improve treatment efficacy.

    To describe the MR imaging and clinical findings of spontaneous spinal epidural hematoma. The MR and clinical findings in six patients (M:F=3D4:2;adult:child=3D3:3) with spontaneous spinal epidural hematoma were reviewed. Five patients without any predisposing factor which might cause the condition and one with acute myelogenous leukemia were included. Emergency surgery was performed in two patients, and the other four were managed conservatively. The epidural lesion involved between three and seven vertebrae (mean:4.5), and relative to the spinal cord was located in the posterior-lateral (n=3D4), anterior (n=3D1), or right lateral (n=3D1) area. The hematoma was isointense (n=3D1) or hyperintense (n=3D5) with spinal cord on T1-weighted images, and hypointense (n=3D2) or hyperintense (n=3D4) on T2-weighted images. It was completely absorbed in four of five patients who underwent follow-up MR imaging, but not changed in one. The clinical outcome of these patients was complete recovery (n=3D4), spastic cerebral palsy (n=3D1), or unknown (n=3D1). Because of the lesion's characteristic signal intensity; MR imaging is very useful in the diagnosis and evaluation of spontaneous spinal epidural hematoma. (author)

    Hutzelmann, A.; Palmie, S.; Freund, M.

    1997-01-01

    Purpose: In cases of lumbar vertebral metastasis associated with anterior epidural carcinomatous infiltration, we have observed that infiltrations tend to respect the midline. This study led to the systematic recognition of these phenomena in vertebral metastases. Materials and Methods: 11 Patients with 17 vertebral metastases and adjacent anterior epidural infiltration were reviewed retrospectively. All cases were studied by MRI. The routinely used imaging technique included spin echo (SE) T 1 and T 2 weighted sequences in the sagittal plane native and T 1 -SE without and with Gd-DTPA in the axial planes. The radiological findings of these phenomena and the anatomy were studied. Results: We observed these phenomena to be uni- or bilateral in 88.3% of all cases with intraspinal anterior epidural carcinomatous infiltration, especially in that part of the vertebral body where the basal vertebral venous plexus was located. Conclusion: We conclude that vertebral metastases respect the midline. We interpret this fact as being due the anatomy of the vertebral body and especially its stabilization by the posterior longitudinal ligament. These findings may be helpful in the differential diagnosis of vertebral body metastases with epidural infiltration in contrast to intraspinal processes which proceed with the destruction of the vertebral body.

    Epidural use has been associated with a higher rate of neonatal sepsis evaluation. Epidural-related fever explains some of the increase but not the excess of neonatal sepsis evaluations in afebrile women We studied 1109 women who had singleton term pregnancies and who presented in spontaneous labor and were afebrile during labor (24 hours or sustained fetal heart rate of >160 beats per minute. Minor criteria included a maternal temperature of 99.6 degrees F to 100.4 degrees F, rupture of membranes for 12 to 24 hours, maternal admission white blood cell count of >15 000 cells/mL(3), or an Apgar score of 24 hours (6.2% vs 3.4%), low-grade fever of 99.6 degrees F to 100.4 degrees F (24.3% vs 5.2%), and rupture of membranes for 12 to 24 hours (21.4% vs 5.2%) than women without epidural. Epidural analgesia is associated with increased rates of major and minor criteria for neonatal sepsis evaluations in afebrile women.

    Regional cerebral blood flow (rCBF) was determined by SPECT of 133-Xe inert gas washout in 18 hypertensive patients (PTS) upon admission and after treatment with oral clonidine (CL, 0.2 mg, then 0.1 mg/hr until diastolic pressure reached 105 mm Hg or fell by 30 mm Hg). CL reduced mean arterial pressure (MAP) from 160 (200/140) to 133 (150/100) mm Hg over 4-6 hr. RCBF was quantitated in 14 gray matter regions from cross-sectional images and analyzed for differences from normal controls and changes with CL. Initial rCBF was lower in HI PTS than in either normal controls of LO PTS in all brain regions. CL lowered MAP in HI PTS by 52 +- 15 mm Hg and caused reduction in all gray matter regions except right frontal and right temporal (mean reduction 5 +- 2 ml/min/100 g, rho<.05). RCBF images were also evaluated by two trained observers for initial regional defects and for changes with CL. LO PTS were more likely to have defects in rCBF images at rest which would resolve with CL. HI PTS frequently had normal images at rest and developed defects with CL. In summary, the study suggests that SPECT may be useful in detecting rCBF abnormalities in hypertensive PTS at rest and following reductions in MAP

    To describe the use and adverse effects of chloroprocaine for epidural analgesia in young infants for infusion durations greater than 3.5 hours. A retrospective cohort review of the electronic medical record over a 14-month period. The level IV neonatal intensive care unit of a 414-bed free-standing children's hospital. Eighteen infants (mean age, 1.7 ± 1.8 months [0.03-6.3]; mean weight, 3.8 ± 1.3 kg [1.56-6.9]; n = 10 [55%] males) received 1% chloroprocaine for epidural analgesia postoperatively for up to 96-hour duration and met criteria for inclusion. Dosing requirements, placement of epidural catheter, supplementary analgesic therapy, respiratory support, vital signs, and incidence of adverse events associated with local anesthetics were collected. Epidural catheter placement was caudal (n = 8), lumbar (n = 6), or thoracic (n = 4). Mean operative time was 2.48 ± 1 hour (1-5). Initial chloroprocaine dose was 1.3 ± 0.5 mL/h (0.4-2.5) (3.5 ± 1 mg/kg per hour [1.4-5]) with a maximum dose of 1.5 ± 0.6 mL/h (0.4-3) (4.2 ± 1.1 mg/kg per hour [2.2-6.1]). Duration of epidural analgesia was 48.3 ± 21.5 hours (10-96). Duration of epidural infusion did not influence dosing requirement, suggesting the absence of drug tachyphylaxis. All patients received intermittent doses of opioid and nonopioid pain medications while receiving chloroprocaine. Two mechanically ventilated patients required continuous infusion of opioids. No adverse events were directly attributed to chloroprocaine use. Epidural 1% chloroprocaine, in doses of 0.4-3 mL/h (1.5-6.1 mg/kg per hour), was well tolerated in both mechanically ventilated and spontaneously breathing infants for up to 96 hours with no identified adverse effects or tachyphylaxis.

    Alternatives to adrenaline with lignocaine local anesthesia, such as clonidine, have been trialed in various randomized, controlled trials. Therefore, the aim of the present systematic review was to compile the available evidence on using clonidine with lignocaine for dental anesthesia. Electronic databases were searched for eligible studies. A data-extraction form was created, extracted data were analyzed using non-Cochrane mode in RevMan 5.3 software. Heterogeneity between the studies were assessed using the forest plot, I 2 statistics (where >50% was considered to have moderate-to-severe heterogeneity), and χ 2 -test. Random-effects models were used because of moderate heterogeneity. Five studies were included for the final review. While clonidine was found to significantly shorten the onset of local anesthesia when measured subjectively, no significant difference was observed objectively. No significant difference was observed in the duration and postoperative analgesia. Stable hemodynamic parameters within the safe range were observed postoperatively when clonidine was used. Clonidine could be considered as an alternative to adrenaline in cases of contraindications to adrenaline, such as like cardiac abnormalities, hypertension, and diabetes. © 2017 John Wiley & Sons Australia, Ltd.

    Paraplegia is an uncommon yet devastating complication following thoracotomy, usually caused by compression or ischemia of the spinal cord. Ischemia without compression may be a result of global ischemia, vascular injury and other causes. Epidural anesthesia has been implicated as a major cause. This report highlights the fact that perioperative cord ischemia and paraplegia may be unrelated to epidural intervention. A 71-yr-old woman was admitted for a left upper lobectomy for resection of a non-small cell carcinoma of the lung. The patient refused epidural catheter placement and underwent a left T5-6 thoracotomy under general anesthesia. During surgery, she was hemodynamically stable and good oxygen saturation was maintained. Several hours following surgery the patient complained of loss of sensation in her legs. Neurological examination disclosed a complete motor and sensory block at the T5-6 level. Magnetic resonance imaging (MRI) revealed spinal cord ischemia. The patient received iv steroid treatment, but remained paraplegic. Five months following the surgery there was only partial improvement in her motor symptoms. A follow-up MRI study was consistent with a diagnosis of spinal cord ischemia. In this case of paraplegia following thoracic surgery for lung resection, epidural anesthesia/analgesia was not used. The MRI demonstrated evidence of spinal cord ischemia, and no evidence of cord compression. This case highlights that etiologies other than epidural intervention, such as injury to the spinal segmental arteries during thoracotomy, should be considered as potential causes of cord ischemia and resultant paraplegia in this surgical population.

    The caudal approach to the epidural space has been used for decades to treat low back pain caused by lumbosacral root compression. The use of fluoroscopy during epidural steroid injection is the preferred method for placing the needle more accurately in the sacral hiatus, but it carries the risk of radiation hazard. The aim of the study was to assess the anatomical structure of the sacral hiatus and the feasibility of caudal epidural injections under ultrasound guidance. Two hundred and forty patients (male = 100, female = 140) with low back pain and sciatica who were candidates for caudal epidural injection were enrolled into this study. Ultrasound images of the sacral hiatus and bilateral cornua were obtained by a real-time linear array ultrasound transducer. The distance between bilateral cornua and the anterior and posterior wall of the sacrum were measured at the base (sacral hiatus). Under the guide of ultrasonography, we defined the injection successful if turbulence of medication fluid was observed in the sacral canal, but correct placement of the needle and injectant was confirmed on fluoroscopic view as the gold standard technique. The epidurogram showed that the injection was successful in 230 of the 240 patients (95.8%). In eight patients, the injection was not in the correct place in the sacral canal. The sacral hiatus could not be identified by ultrasound images in only two patients who had a closed sacral hiatus identified by fluoroscopy. The mean distance of the sacral hiatus was 4.7 ± 1.7 mm and the mean distance between bilateral cornua was 18.0 ± 2.8 mm. The mean duration of the procedure was 10.8 ± 6.8 minutes. No major complication was observed in the next month. In conclusion, ultrasound could be used as a safe, fast and reliable modality to observe the anatomic variation of the sacral hiatus and to perform caudal epidural injections

    Previous studies have shown that preincisional epidural morphine, bupivacaine, and ketamine combined with epidural anesthesia (EA) and general anesthesia (GA) provided pre-emptive analgesia for upper abdominal surgery. Recent studies reported that ultralow-dose naloxone enhanced the antinociceptive effect of morphine in rats. This study investigated the benefits of preincisional and postoperative epidural morphine + ropivacaine + ketamine + naloxone (M + R + K + N) treatment for achieving postoperative pain relief in upper abdominal surgery. Eighty American Society of Anesthesiology I-II patients scheduled for major upper abdominal surgery were allocated to four groups in a randomized, single-blinded study. All patients received combined GA and EA with a continuous epidural infusion of 2% lidocaine (6-8 mL/h) 30 minutes after pain regimen. After GA induction, in Group I, an epidural pain control regimen (total 10 mL) was administered using 1% lidocaine (8 mL) + morphine (2 mg) + ropivacaine (20 mg; M + R); in Group II, 1% lidocaine 8 (mL) + morphine (2 mg) + ropivacaine (20 mg) + ketamine (20 mg; M + R + K); in Group III, 1% lidocaine (8 mL) + morphine (2 mg) + ropivacaine (20 mg) + naloxone (2 μg; M + R + N); and in Group IV, 1% lidocaine (8 mL) + morphine (2 mg) + ropivacaine (20 mg) + ketamine (20 mg) + naloxone (2 μg; M + R + K + N), respectively. All patients received patient-controlled epidural analgesia (PCEA) with different pain regimens to control subsequent postoperative pain for 3 days following surgery. During the 3-day period following surgery, PCEA consumption (mL), numerical rating scale (NRS) score while cough/moving, and analgesic-related adverse effects were recorded. Total PCEA consumption for the 3-day observation period was 161.5±17.8 mL, 103.2±21.7 mL, 152.4±25.6 mL, and 74.1±16.9 mL for Groups I, II, III, and IV, respectively.

    This study looks into the efficacy and safety of the transforaminal lumbar epidural steroid injection (TLESI) applied to patients with radiculopathy due to lumbar disk herniation. The patients' files which were applied TLESI, were retrospectively scanned. Patients who did not respond to one-month conservative treatment and who were detected to have bulging or protruding lumbar disk herniation as a result of imaging methods were included in the study. All applications were performed with C-arm fluoroscopy under local anesthesia by outpatient method. In all cases, a mix of 80 mg triamsinolone and 0.25% bupivacaine, was transforaminally injected to the anterior epidural area. Initial VAS pain scores were compared with the values of the 1, 3 and 6th months after the application. Patient satisfaction was determined through scoring. Furthermore, early and late term complications were collected for evaluation. A total of 222 patients were administered TLESI 460 times (average: 2.1, repeat interval: 1-6 times). The applications were carried out most frequently at the levels of L4-L5 and L5-S1. While the initial VAS score average was 8.2±0.7, after TLESI, it was 5.0±1.6, 4.8±1.5 and 5.1±1.5 in the 1, 3 and 6th months, respectively. 63.9% of the patients (n=142) defined the treatment as 'good and excellent'. No major complications were experienced and the overall minor complication rate was 11.1%. It was seen that TLESI was an efficient and safe method in the short and medium term.

    Epidural analgesia is an established method for pain management. The failure rate is 8% to 12% due to technical difficulties (catheter dislocation and/or disconnection; partial or total catheter occlusion) and management. The mechanical properties of the catheters, like tensile strength and flow rate, may also be affected by the analgesic solution and/or the tissue environment. We investigated the tensile strength and perfusion pressure of new (n=20), perioperatively (n=30), and postoperatively (n=73) used epidural catheters (20-gauge, polyamide, closed tip, 3 side holes; Perifix [B. Braun]). To prevent dislocation, epidural catheters were taped (n=5) or fixed by suture (n=68) to the skin. After removal, mechanical properties were assessed by a tensile-testing machine (INSTRON 4500), and perfusion pressure was measured at flow rates of 10, 20, and 40 mL/h. All catheters demonstrated a 2-step force transmission. Initially, a minimal increase of length could be observed at 15 N followed by an elongation of several cm at additional forces (7 N). Breakage occurred in the control group at 23.5±1.5 N compared with 22.4±1.6 N in perioperative and 22.4±1.7 N in postoperative catheters (Ptensile strength, whereas perfusion pressure at clinically used flow rates (10 mL/h) increased significantly from 19±1.3 to 44±72 mm Hg during long-term (≥7 days) epidural analgesia (Ptensile strength or perfusion pressure. Epidural catheter use significantly increases the perfusion pressure and decreases the tensile strength. Copyright © 2011 by American Society of Regional Anesthesia and Pain Medicine

    Full Text Available Multimodal analgesia refers to the practice of combining multiple analgesic drug classes or techniques to target different points along the pain pathway. The objective of this work was to evaluate clinically if ketoprofen associated or not with intravenous or epidural morphine provided adequate postoperative analgesia in bitches undergoing ovariosalpingohysterectomy (OSH. Forty healthy female dogs, weighing 10.7±6.0 kg, sedated with acepromazine (0.05mg kg –1.iv, induced with propofol (5 mg.kg-1. iv and maintained with isoflurane anesthesia, were distributed into four groups of 10 animals each. After stabilization of inhalation anesthesia, the bitches in Miv and CMiv groups received 0.2 mg.kg-1 of morphine intravenously diluted in 10ml of saline; whereas Mep and CMep groups received 0.1mg.kg-1 of epidural morphine. Thirty minutes after premedication, 2.0mg.kg-1.im of ketoprofen was administered in groups CMiv and CMep. Heart and respiratory rate, systolic blood pressure, and rectal temperature were measured. The degree of analgesia was assessed by a blind study in the following 6 hours after surgery, using a descriptive scale and a scale composed by physiologic and behavioral parameters. An statistical analysis was performed using the Tukey-Kramer test and nonparametric Kruskal-Wallis test, with statistical significance of 5%. There was no important difference between the four groups regarding postoperative analgesia, heart and respiratory rate, systolic blood pressure and rectal temperature. According to the results it can be concluded that the use of ketoprofen associated with intravenous or epidural morphine provided adequate and safe analgesia in the first six hours of postoperative in bitches undergoing ovariohysterectomy, suggesting that there was no analgesic potentiation when both agents were combined.

    Background and Aims: The aim of this study was to evaluate the level of sensory block, onset and duration of motor block, postoperative analgesia, and adverse effects of combination of clonidine and fentanyl given intrathecally with hyperbaric bupivacaine (HB). Material and Methods: Three hundred and twenty eight patients were randomized into four groups. Group bupivacaine (group B) received 15 mg of HB; group bupivacaine clonidine (group BC) received 15 mg of HB plus 25 μg clonidine; group bupivacaine fentanyl (group BF) received 15 mg of HB plus 25 μg fentanyl and group bupivacaine clonidine fentanyl (group BCF) received 15 mg of HB plus 25 μg clonidine and 25 μg fentanyl intrathecally. All groups were evaluated for level of sensory block, onset and duration of motor block, postoperative analgesia, VAS score, sedation score and adverse effects of study drugs. All the data were analyzed using unpaired t-test. P < 0.05 was considered significant. Results: The level of sensory block, onset, and duration of motor block were comparable in all groups. Total duration of analgesia was 407.3 ± 20 min in group BCF compared to 242.1 ± 2 min and 209.2 ± 16 in groups BC and BF, respectively. Lesser doses of rescue analgesic were required in group BCF. The time interval from intrathecal injection to two-segment regression was statistically significant in study groups. Only 2.4% patients showed mild sedation in BCF group. Conclusion: We found that combination of intrathecal clonidine and fentanyl along with bupivacaine increases the total duration of analgesia without significant side effects. PMID:28413281

    In hypertension, there is an autonomic imbalance in which sympathetic activity dominates over parasympathetic control. Parasympathetic activity to the heart originates from cardiac vagal neurons located in the nucleus ambiguus. Presympathetic neurons that project to sympathetic neurons in the spinal cord are located in the ventral brainstem in close proximity to cardiac vagal neurons, and many of these presympathetic neurons are catecholaminergic. In addition to their projection to the spinal cord, many of these presympathetic neurons have axon collaterals that arborize into neighboring cardiorespiratory locations and likely release norepinephrine onto nearby neurons. Activation of alpha(2)-adrenergic receptors in the central nervous system evokes a diverse range of physiological effects, including reducing blood pressure. This study tests whether clonidine, an alpha(2)-adrenergic receptor agonist, alters excitatory glutamatergic, and/or inhibitory GABAergic or glycinergic synaptic neurotransmission to cardiac vagal neurons in the nucleus ambiguus. Cardiac vagal neurons were identified in an in vitro brainstem slice preparation, and synaptic events were recording using whole cell voltage clamp methodologies. Clonidine significantly inhibited GABAergic neurotransmission but had no effect on glycinergic or glutamatergic pathways to cardiac vagal neurons. This diminished inhibitory GABAergic neurotransmission to cardiac vagal neurons would increase parasympathetic activity to the heart, decreasing heart rate and blood pressure. The results presented here provide a cellular substrate for the clinical use of clonidine as a treatment for hypertension as well as a role in alleviating posttraumatic stress disorder by evoking an increase in parasympathetic cardiac vagal activity, and a decrease in heart rate and blood pressure.

    Full Text Available Background and Aims: Use of various adjuvants to spinal anaesthesia is a well-known modality to provide intra- and post-operative analgesia. This study was designed to evaluate and compare the analgesic efficacy of clonidine and magnesium when used as an additive to intrathecal 0.5% hyperbaric bupivacaine. Methods: Ninety patients of the American Society of Anesthesiologists' physical status grade I or II, scheduled for lower abdominal surgery under spinal anaesthesia, were randomly allocated into three groups. Group B received 3 mL of 0.5% hyperbaric bupivacaine with 1 mL of normal saline, Group C received 3 mL of 0.5% hyperbaric bupivacaine with 1 mL (30 μg of clonidine and Group M received 3 mL of 0.5% hyperbaric bupivacaine with 1 mL (50 mg magnesium sulphate. The primary outcome variable was duration of analgesia and secondary outcome variables included onset and duration of sensory and motor block, sedation level and adverse effects. Data were analysed with ANOVA, Kruskal–Wallis and Chi-square tests. Results: The time to first rescue analgesia was significantly (P < 0.01 longer in the Group C (330.7 ± 47.7 min than both Groups. Group M (246.3 ± 55.9 min showed significantly prolonged analgesia than Group B (134.4 ± 17.9 min. Group C and Group M showed significantly prolonged duration of both sensory and motor block compared to Group B. Conclusion: Intrathecal clonidine added to bupivacaine prolongs the duration of post-operative analgesia, and hastens the onset and prolongs the duration of sensory and motor block compared to magnesium or controls.

    The addition of opioids to epidural local anesthetic reduces local anesthetic consumption by 20% but at the expense of side effects and time spent for regulatory compliance paperwork. Epidural neostigmine also reduces local anesthetic use. The authors hypothesized that epidural bupivacaine with neostigmine would decrease total hourly bupivacaine use compared with epidural bupivacaine with fentanyl for patient-controlled epidural analgesia. A total of 215 American Society of Anesthesiologists physical status II, laboring parturients requesting labor epidural analgesia consented to the study and were randomized to receive 0.125% bupivacaine with the addition of either fentanyl (2 μg/ml) or neostigmine (2, 4, or 8 μg/ml). The primary outcome was total hourly local anesthetic consumption, defined as total patient-controlled epidural analgesia use and top-ups (expressed as milliliters of 0.125% bupivacaine) divided by the infusion duration. A priori analysis determined a group size of 35 was needed to have 80% power at α = 0.05 to detect a 20% difference in the primary outcome. Of 215 subjects consented, 151 patients were evaluable. Demographics, maternal and fetal outcomes, and labor characteristics were similar among groups. Total hourly local anesthetic consumption did not differ among groups (P = 0.55). The total median hourly bupivacaine consumption in the fentanyl group was 16.0 ml/h compared with 15.3, 14.6, and 16.2 ml/h in the 2, 4, and 8 μg/ml neostigmine groups, respectively (P = 0.55). The data do not support any difference in bupivacaine requirements for labor patient-controlled epidural analgesia whether patients receive epidural bupivacaine with 2 to 8 μg/ml neostigmine or epidural bupivacaine with 2 μg/ml fentanyl.

The aim of this study was to assess the effect of adjuvants to ropivacaine on the duration of sensory and motor block.Methods: In this double-blind randomized placebo-controlled study, we evaluated the analgesic effect of clonidine or dexamethasone (DXM when added to ropivacaine for hallux valgus surgery. After obtaining institutional ethics research board approval and written informed consent, a total of 72 patients were randomly allocated. Fifty-seven of these patients were statistically analyzed. All patients received an ultrasound-guided single-shot popliteal fossa block with 30 mL of ropivacaine 0.75%, supplemented with saline, clonidine 100 µg, or DXM 5 mg. The primary end point was time to first pain sensation. Secondary end points were time to complete sensory and motor block regression.Results: Compared to saline, duration to first pain sensation was prolonged by 9 hours (mean ± standard deviation: 31±9 hours (42% in the DXM group (P=0.024 and by 6 hours (28±10 hours (27% in the clonidine group (P=0.024.

    Full Text Available Background: Morphine withdrawal usually results in undesired outcomes , despite partial benefits of alternative medication such as methadone, because of the lack of mental sedation during the withdrawal period, may not lead to the desired result. In this study, forced exercise by treadmill is used to manage morphine dependence in animal model. Materials and Methods: Forty adult male mice were divided into 5 groups, from which 4 groups became dependent by increasing daily doses of morphine for 6 days (20-45 mg/kg, SC. Afterwards, the animals were treated for 21 days by either of the following protocol: Positive control (dependent received once daily 45 mg/kg of morphine sulfate (SC for 21 day, group under treatment by clonidine (0.4 mg/kg, SC for 21 day group under treatment by forced exercise by treadmill for 21 day, group under treatment by combination of clonidine (0.4 mg/kg, SC and forced exercise by treadmill for 21day and the negative control group(independent received saline injection like other groups. Each of this administration was injected at 8 AM. Finally, in the test day (day 28, all animals received a single dose of naloxone (3 mg/kg, SC at 8 AM and then were observed for withdrawal signs, and Total Withdrawal Score (TWS was determined as described previously. After withdrawal sign evaluation for evaluation of stress level of dependent mice, blood cortisol and glucose level were measured in non-fasting situations well. Results: This study showed that TWS significantly decreased in all treatment groups in comparison with positive control group (P < 0.001. Moreover, blood cortisol and glucose level significantly decreased in group under treatment by clonidine (0.4 mg/kg and group under treatment by combination of clonidine (0.4 mg/kg and forced exercise by treadmill groups in comparison with control positive (dependent (P < 0.05. Conclusion: This study suggested that forced exercise can be useful as adjunct therapy in dependent people

    The specific binding of tritiated (3H)-clonidine, an alpha 2-adrenergic receptor agonist, to platelet membranes was measured in normal subjects and in patients with major depressive disorder. The number of platelet alpha 2-adrenergic receptors from the depressed group was significantly higher than that found in platelets obtained from the control population. Treatment with tricyclic antidepressant drugs led to significant decreases in the number of platelet alpha 2-adrenergic receptors. These results support the hypothesis that the depressive syndrome is related to an alpha 2-adrenergic receptor supersensitivity and that the clinical effectiveness of tricyclic antidepressant drugs is associated with a decrease in the number of these receptors

    Evidence suggests that complex regional pain syndrome (CRPS) is a manifestation of microvascular dysfunction. Topical combinations of α2-adrenergic receptor agonists or nitric oxide donors with phosphodiesterase or phosphatidic acid inhibitors formulated to treat microvascular dysfunction have been shown to reduce allodynia in a rat model of CRPS-I. Driven by these findings, we assessed the outcomes of CRPS patients treated with a compound analgesic cream (CAC) consisting of ketamine 10%, pentoxifylline 6%, clonidine 0.2%, and dimethyl sulfoxide 6% to 10%. An audit was conducted on 13 CRPS patients who trialed the CAC. A detailed report was compiled for each patient which comprised baseline characteristics, including CRPS description, previous treatments, and pain scores (numerical pain rating scale; 0 to 10). Recorded outcomes consisted of pain scores, descriptive outcomes, and concurrent medications/treatments, for which basic analysis was performed to determine the effectiveness of the CAC. Case reports are presented for 3 patients with varying outcomes. Nine patients (69%) reported pain/symptom reduction (4.4 ± 2.1 vs. 6.3 ± 1.9) with use of the CAC. Six patients reported sustained benefits after 2 months of CAC use, and 2 patients reported complete resolution of pain/symptoms: one had early CRPS-I and the other received a partial CRPS diagnosis. An otherwise medication refractory and intolerant patient found partial benefit with the CAC. These results demonstrate promise for this topical combination as a useful treatment in multimodal therapy for patients with CRPS, with the potential to resolve pain/symptoms in early CRPS patients. © 2015 World Institute of Pain.

    The authors investigated whether the reduction of arterial pressure, induced by the oral administration of clonidine (CLO), enalapril (EN), and nifedipine (NIF), has any effect on peritoneal transport rates. The study was performed in nine hypertensive patients undergoing continuous ambulatory peritoneal dialysis (CAPD). The patients were submitted to administration of CLO, EN, and NIF, each in randomized succession for two weeks, after withdrawal of any hypotensive therapy for eight days (washout period). The nine patients underwent a four-hour dwell exchange using a 2.27 g/dL glucose two-liter bag after washout and after each hypotensive period. The following parameters were analyzed: mean arterial pressure (MAP), performed in the sitting position; net ultrafiltration; effluent/initial dialysate glucose ratio (GL D/Do); peritoneal clearance of K, BUN, creatinine (Cr), phosphate, beta-2 microglobulin (beta 2), total proteins, and the ratio between beta 2 and Cr clearance. Moreover, residual renal Cr and beta 2 clearances were analyzed. The three drugs significantly reduced MAP at a similar rate. The peritoneal transport parameters after CLO were similar to the results in the washout period. On the contrary, after EN and NIF therapy, Cr and beta 2 clearances were significantly increased, and GL D/Do decreased in comparison to the washout period. The other peritoneal transport parameters after EN and NIF were similar to the washout period. Residual renal Cr and beta 2 clearances after the three drugs were similar to those in the washout. these data suggest that after two weeks of therapy with EN and NIF, glucose, Cr, and beta 2 peritoneal transports are influenced by these hypotensive drugs irrespective of the effect on the arterial pressure.(ABSTRACT TRUNCATED AT 250 WORDS)

    Spinal epidural extramedullary haematopoiesis is very rare in thalassaemia. A 27-year-old man with thalassaemia intermedia presented with symptoms and signs of spinal cord compression. MRI showed a thoracic spinal epidural mass, representing extramedullary haematopoietic tissue, compressing the spinal cord. Following radiotherapy, serial MRI revealed regression of the epidural mass and gradual resolution of spinal cord oedema. (orig.) With 3 figs., 6 refs.

    Pain during childbirth is arguably the most severe pain some women may experience in their lifetime. Epidural analgesia is an effective form of pain relief during labour. Many women have concerns regarding its safety. Furthermore, epidural services and anaesthetic support may not be available consistently across all centres. Observational data suggest that early initiation of epidural may be associated with an increased risk of caesarean section, but the same findings were not seen in recent randomised controlled trials. More recent guidelines suggest that in the absence of a medical contraindication, maternal request is a sufficient medical indication for pain relief during labour. The choice of analgesic technique, agent, and dosage is based on many factors, including patient preference, medical status, and contraindications. There is no systematically reviewed evidence on the maternal and foetal outcomes and safety of this practice. This systematic review aimed to summarise the effectiveness and safety of early initiation versus late initiation of epidural analgesia in women. We considered the obstetric and fetal outcomes relevant to women and side effects of the treatments, including risk of caesarean section, instrumental birth and time to birth. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (12 February 2014), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2014, Issue 1), MEDLINE (January 1966 to February 2014), Embase (January 1980 to February 2014) and reference lists of retrieved studies. We included all randomised controlled trials involving women undergoing epidural labour analgesia that compared early initiation versus late initiation of epidural labour analgesia. Two review authors independently assessed trials for inclusion, extracted the data and assessed the trial quality. Data were checked for accuracy.

    Epidural block under general anesthesia has been widely used to control postoperative pain. In this anesthetic state many hemodynamic parameters are changed. Moreover pulse transit time is influenced by this memodynamic change. PPT change in the finger and the toe due to relaxation of arterial wall muscle after general anesthesia and epidural block under general anesthesia. This study, in the both general anesthesia and epidural block under general anesthesia, ΔPTT of the toe and of the finger are measured. In addition, ΔPTT(toe-finger) of the epidural block under general anesthesia and of the general anesthesia were compared

    Purpose: The consequences from the injection of different types of drugs in the epidural space remains unknown. Increasing evidence suggests that localized inflammation, fibrosis, and arachnoiditis can complicate sequential epidural blockades, or even epidural contrast injection. We investigate the in vivo effect of epidural injections in the epidural space in an animal model. Materials and Methods: A group of ten male adult pigs, five punctures to each at distinct vertebral interspaces under general anesthesia, were examined, testing different drugs, used regularly in the epidural space (iopamidol, methylprednisolone acetate, ropivacaine). Each site was marked with a percutaneous hook wire marker. Histological analysis of the epidural space, the meninges, and the underlying spinal cord of the punctured sites along with staining for caspase-3 followed 20 days later. Results: The epidural space did not manifest adhesions or any other pathology, and the outer surface of the dura was not impaired in any specimen. The group that had the contrast media injection showed a higher inflammation response compared to the other groups (P = 0.001). Positive staining for caspase-3 was limited to <5% of neurons with all substances used. Conclusion: No proof of arachnoiditis and/or fibrosis was noted in the epidural space with the use of the above-described drugs. A higher inflammation rate was noted with the use of contrast media.

    Solitary spinal epidural cavernous angiomas are rare lesions, especially in paediatric age group. They are infrequently considered in the differential diagnosis of spinal epidural masses in children. We report a case of solitary epidural cavernous angioma of the thoracic spine in a child presenting with acute onset of back pain and myelopathy. Magnetic resonance imaging of the thoracic spine demonstrated a posterior epidural mass at T6-T8 levels with compression of the spinal cord. Using microsurgical technique and bipolar coagulation, total excision of the lesion was achieved. Histopathological examination confirmed the diagnosis of cavernous angioma. At the five-year follow-up, there was no recurrence of the tumour. (author)

    To evaluate the effect of thoracic epidural anesthesia (TEA) on tissue oxygen delivery and utilization in patients undergoing cardiac surgery. This prospective observational study was conducted in a tertiary referral heart hospital. A total of 25 patients undergoing elective off-pump coronary artery bypass surgery were enrolled in this study. All patients received thoracic epidural catheter in the most prominent inter-vertebral space between C7 and T3 on the day before operation. On the day of surgery, an arterial catheter and Swan Ganz catheter (capable of measuring cardiac index) was inserted. After administering full dose of local anesthetic in the epidural space, serial hemodynamic and oxygen transport parameters were measured for 30 minute prior to administration of general anesthesia, with which the study was culminated. A significant decrease in oxygen delivery index with insignificant changes in oxygen extraction and consumption indices was observed. We conclude that TEA does not affect tissue oxygenation despite a decrease in arterial pressures and cardiac output.

    Full Text Available Spontaneous spinal epidural hematoma is a rare cause of acute spinal cord compression. A 25-year-old male presented with a history of sudden onset of complete quadriplegia with sensory loss below the neck along with loss of bowel and bladder control. He had no history of any constitutional symptoms. He reported 10 days later. He was managed conservatively and after two weeks of intensive rehabilitation he had complete neural recovery. The spontaneous recovery of neurological impairment is attributed to the spreading of the hematoma throughout the epidural space, thus decreasing the pressure with partial neural recovery. Conservative treatment is a fair option in young patients who present late and show neurological improvement. The neurological status on presentation will guide the further approach to management.

    Central deposition of fat is a well-known clinical feature of chronically elevated corticosteroid levels. Rarely described is increased extradural fat causing compression of the spinal cord and neurologic deficits. Twelve previously reported and five new cases of epidural lipomatosis are presented. Representative examples of the common myelographic and CT findings in this disorder are shown. In addition, previously undescribed examples of epidural lipomatosis demonstrating (1) the MR findings, (2) no associated myelographic block, (3) lipomatosis in both the thoracic and lumbar regions, and (4) a case in a nonobese patient without known steroid use are presented. The importance of considering this entity in the appropriate clinical setting (chronic exogenous steroid use) even with a normal myelogram is stressed

    Full Text Available Background. It was suggested that labor may influence the spread of intrathecal bupivacaine using combined spinal epidural (CSE technique. However, no previous studies investigated this proposition. We designed this study to investigate the spinal block characteristics of plain bupivacaine between nonlaboring and laboring parturients using CSE technique. Methods. Twenty-five nonlaboring (Group NL and twenty-five laboring parturients (Group L undergoing cesarean delivery were enrolled. Following identification of the epidural space at the L3-4 interspace, plain bupivacaine 10 mg was administered intrathecally using CSE technique. The level of sensory block, degree of motor block, and hemodynamic changes were assessed. Results. The baseline systolic blood pressure (SBP and the maximal decrease of SBP in Group L were significantly higher than those in Group NL (=0.002 and =0.03, resp.. The median sensory level tested by cold stimulation was T6 for Group NL and T5 for Group L (=0.46. The median sensory level tested by pinprick was T7 for both groups (=0.35. The degree of motor block was comparable between the two groups (=0.85. Conclusion. We did not detect significant differences in the sensory block levels between laboring and nonlaboring parturients using CSE technique with intrathecal plain bupivacaine.

    The paper analyzes some experience gained in using various modes of regional anesthesia as an anesthetic appliance at cesarean sections and comparatively characterizes various types of central segmental blocks. The results of 213 cases of cesarean section performed under spinal or combined spinal and epidural anesthesia (CSEA) were generalized by the following parameters: block onset, maternal and fetal action, the quality of anesthesia and postoperative analgesia, which leads to the conclusion that CSEA is the method of choice.

    Full Text Available Achondroplasia is the commonest form of short-limbed dwarfism and occurs in 1:26,000- 40,000 live births. This is an autosomal dominant disorder with abnormal endochondral ossification whereas periosteal and intramembranous ossification are normal. The basic abnormality is a disturbance of cartilage formation mainly at the epiphyseal growth plates and at the base of the skull. The anesthetic management of achondroplastic dwarfs is a challenge to the anesthesiologist. Both regional as well as general anesthesia have their individual risks and consequences. We report a case of an achondroplastic dwarf in whom combined spinal epidural anesthesia was used for fixation of a fractured femur. The patient had undergone previous femur surgery under general anesthesia since he had been informed that spinal anesthesia could be very problematic. There was no technical difficulty encountered during the procedure and an adequate level was achieved with low-dose local anesthetics without any problem. Postoperative pain relief was offered for three consecutive postoperative days using epidural tramadol. We discuss the anesthetic issues and highlight the role of combined spinal epidural anesthesia with low-dose local anesthetics in this patient. This approach also helped in early ambulation and postoperative pain relief.

    2014-09-01

    Full Text Available Spontaneous spinal epidural hematoma is an uncommon cause of acute non-traumatic myelopathy and may present with various clinical phenotypes. Focal neurological symptoms can result in overlooking this differential diagnosis in patients presenting with neurological deficits and assuming the diagnosis of a stroke. Therefore, a thorough documentation of patient history is of great importance, since this can reveal symptoms suggestive of a different etiology. Here, we present a case of an 80-year-old female who was admitted with a hemiparesis without cortical or cranial neurological abnormalities. She mentioned of preceding shoulder and neck pain. Diagnosis of epidural hematoma was made by cervical magnetic resonance imaging. Symptoms resolved partially after surgical intervention. Our case illustrates the variation in the clinical presentation of spontaneous spinal epidural hematoma which can be misdiagnosed as stroke. Therefore, in patients with preceding neck, shoulder or interscapular pain and focal neurological deficits, this diagnosis should be included in the differential, particularly when cortical and cranial signs are lacking

    Today's implanted brain-computer interfaces make direct contact with the brain or even penetrate the tissue, bearing additional risks with regard to safety and stability. What is more, these approaches aim to control prosthetic devices as assistive tools and do not yet strive to become rehabilitative tools for restoring lost motor function. We introduced a less invasive, implantable interface by applying epidural electrocorticography in a chronic stroke survivor with a persistent motor deficit. He was trained to modulate his natural motor-related oscillatory brain activity by receiving online feedback. Epidural recordings of field potentials in the beta-frequency band projecting onto the anatomical hand knob proved most successful in discriminating between the attempt to move the paralyzed hand and to rest. These spectral features allowed for fast and reliable control of the feedback device in an online closed-loop paradigm. Only seven training sessions were required to significantly improve maximum wrist extension. For patients suffering from severe motor deficits, epidural implants may decode and train the brain activity generated during attempts to move with high spatial resolution, thus facilitating specific and high-intensity practice even in the absence of motor control. This would thus transform them from pure assistive devices to restorative tools in the context of reinforcement learning and neurorehabilitation.

    2013-01-01

    Retrospective studies have associated early epidural analgesia with cesarean delivery, but prospective studies do not demonstrate a causal relationship. This suggests that there are other variables associated with early epidural analgesia that increase the risk of cesarean delivery. This study was undertaken to determine the characteristics associated with early epidural analgesia initiation. Information about women delivering at 37 weeks or greater gestation with epidural analgesia, who were not scheduled for cesarean delivery, was extracted from the McGill Obstetric and Neonatal Database. Patients were grouped into those who received epidural analgesia at a cervical dilation of ≤3 cm and >3 cm. Univariable and multivariable logistic regression was used to determine the maternal, neonatal, and labor characteristics that increased the risk of inclusion in the early epidural group. Of the 13,119 patients analyzed, multivariable regression demonstrated odds ratios (OR) of 2.568, 5.915 and 10.410 for oxytocin augmentation, induction, and dinoprostone induction of labor (P analgesia (OR 0.780, P analgesia (P neonatal weight (OR 0.943, P analgesia. Labor augmentation and induction, nulliparity, rupture of membranes spontaneously and before labor starts, increasing maternal weight, and decreasing neonatal weight are associated with early epidural analgesia. Many of these variables are also associated with cesarean delivery.

    Preeclampsia is an exaggerated maternal inflammatory state with over-expression of placental soluble fms-like tyrosine kinase 1 (sFlt-1). It is also associated with shallow trophoblast invasion and inadequate transformation of uterine spiral arteries. Antihypertensive drugs administrated in preeclampsia to control blood pressure have been reported to regulate placental and circulating cytokine production from women with preeclampsia. Whether they could modulate the interaction between trophoblast and endothelial cells are not investigated. This study is to examine the effect of pharmacological dose of anti-hypertensive hydralazine, clonidine and labetalol on trophoblast cell integration into inflammatory TNF-a pre-exposed endothelial cellular networks. Human uterine myometrial microvascular endothelial cells (UtMVECs) were pre-incubated with (or without) low dose (0.5ng/ml) inflammatory TNF-a or TNF-a plus sFlt-1 (100ng/ml) for 24hours. These cells were labelled with red fluorescence and seeded on a 24-well culture plate coated with Matrigel. Endothelial tubular structures appeared within 4hours. Green fluorescent-labelled HTR-8/SVneo trophoblast cells were then co-cultured with endothelial cells, with (or without) hydralazine (10μg/ml), clonidine (1.0μg/ml) or labetalol (0.5μg/ml). Red and green fluorescent images were captured after 24hours. Drug effect on HTR-8 cells integration into endothelial cellular networks was quantified by Image Analysis software. The conditioned media were also collected to measure concentrations of free VEGF, PLGF and sFlt-1 by ELISA. When HTR-8/SVneo trophoblast cells were co-cultured with TNF-a pre-incubated endothelial cells, hydralazine and clonidine can significantly increase the trophoblast integration into endothelial cellular networks. This increase was not seen if co-cultured with normal endothelial cells (without TNF-a pre-incubation) or with TNF-a plus sFlt-1 treated endothelial cells. Labetalol could increase the HTR-8

    An epidural injection of saline was reported to extend spinal anesthesia because of a volume effect. The aim of this study was to evaluate the influence of the baricity of spinal local anesthetics upon the extension of spinal anesthesia by epidural injection of saline. Forty patients undergoing elective lower-limb surgery were randomly allocated to four groups of 10 patients each. Group A received no epidural injection after the spinal administration of hyperbaric tetracaine (dissolved in 10% glucose). Group B received an epidural injection of 8 ml of physiological saline 20 min after spinal hyperbaric tetracaine. Group C received no epidural injection after spinal isobaric tetracaine (dissolved in physiological saline). Group D received an epidural injection of 8 ml of saline 20 min after spinal isobaric tetracaine. The level of analgesia was examined by the pinprick method at 5-min intervals. The levels of analgesia 20 min after spinal anesthesia were significantly higher in hyperbaric groups than in isobaric groups [T5 (T2-L2) vs. T7 (T3-12)]. After epidural injection of saline, the levels of analgesia in groups B and D were significantly higher than in groups A and C. The segmental increases after epidural saline injection were 2 (0-3) in group B and 2 (1-7) in group D. Sensation in the sacral area remained 20 min after spinal block in one patient in group D; however, it disappeared after epidural saline injection. In this study, 8 ml of epidural saline extended spinal analgesia. However, there was no difference between the augmenting effect in isobaric and hyperbaric spinal anesthesia. We conclude that the reinforcement of spinal anesthesia by epidural injection of saline is not affected by the baricity of the spinal anesthetic solution used.

    Full Text Available Introduction: The labor pain affect to all pregnant woman and it has biochemical and physiological changes that affect to mother and fetus and interact with your normal evolution. Currently there are analgesic techniques to less effectively labor pain, to provide a high satisfaction level and supply clinical and laboratory beneficial outcomes. In own context these techniques are very low used. Objective: To describe the use of epidural analgesic procedures in a pregnancy woman group during labor at the Universitarian Hospital San Jose – Popayan, Colombia. Materials and methods: Case series design. We recollected information of patients from Obstetric service during two months of 2006. The patient’s information was recollected from medical history with an instrument that content variables related with the analgesic technique and labor. The analyses were performed using descriptive statistics Results: 41 pregnant woman with a mean age of 23,4 were included. 65,9% were nulliparous and 85,4% were term pregnancy. At the moment of dural puncture the dilation and EVA pain scale mode was 6 and 8 respectively. The latency mean was 14,1 minutes. 95,1% were require a booster applied in a mean of 80 minutes and 61% were required a second booster applied in a mean of 49 min after that. The way of termination of pregnancy was vaginal predominantly. Conclusions: The results of this study are congruent to reporting in the world literature.

    Spinal epidural abscesses are an uncommon cause of spinal cord injury but, depending on the size and presence of neurological deficits, urgent neurosurgical intervention may be required. We present a unique case of a patient presenting with a spinal epidural collection several days after a fall. While a spinal epidural hematoma was suspected based on the patient's history and MRI findings, a spinal epidural abscess was found during surgery. The patient underwent laminectomy and instrumented fusion with successful treatment of her infection.

    Full Text Available Background and Aims: Endoscopic sinus surgery (ESS provides a challenge and an opportunity to the anesthesiologists to prove their mettle and give the surgeons a surgical field which can make their delicate surgery safer,more precise and faster. The aim of the study was to evaluate the surgical field and the rate of blood loss in patients premedicated with oral clonidine versus oral diazepam for endoscopic sinus surgery. Material and Methods: ASA I or II patients who were scheduled to undergo ESS were randomly allocated to group D (n = 30 or group C (n = 30. The patients′ vital parameters, propofol infusion rate, and rate of blood loss were observed and calculated. The surgeon, who was blinded, rated the visibility of the surgical field from grade 0-5. Results: In the clonidine group, the rate of blood loss, the surgical time, propofol infusion rate was found to be statistically lower as compared to the diazepam group. Also a higher number of patients in the clonidine group had a better surgical score (better surgical field than the diazepam group and vice versa. Conclusions: Premedication with clonidine as compared to diazepam, provides a better surgical field with less blood loss in patients undergoing ESS.

    Despite significant advances in the conservative management of pyogenic spondylodiscitis, consecutive instability, deformity, and/or neurologic compromise demands a prompt surgical intervention. However, in rare cases involving additional multilevel epidural abscess formation, the appropriate surgical strategy remains controversial. In this retrospective cohort analyses, we evaluated the efficacy of a single-stage posterior approach with the addition of a one-time multilevel epidural lavage via the surgically exposed interlaminar fenestration of the infected segment. From January 2009 through December 2010, 73 patients presenting pyogenic spondylodiscitis with instability of the lumbar spine were admitted. In all cases, the surgical strategy included a radical resection of the affected intervertebral disc and stabilization by intervertebral fusion using a titanium cage with autologous bone grafting in a level-dependent posterior approach with additional pedicle screw-and-rod instrumentation. In cases where multilevel abscess formation was evident, the standard surgical procedure was complemented by drainage and irrigation of the abscess from posterior by carefully advancing a soft infant feeding tube via the surgically exposed epidural space under fluoroscopic guidance. All patients received complementary oral antibiotic therapy for 12 weeks and were followed-up for a minimum of 12 months postoperatively. Ten patients (three male and seven female patients; mean age: 64.9 ± 10.9 years) presented with an additional lumbar epidural abscess extending beyond three levels proximal or distal to the infected disc. In all 10 patients the laboratory-chemical inflammatory parameters (leukocyte count, C-reactive protein) remained within the physiologic range after completing antibiotic therapy throughout the 1-year follow-up period. The plain radiographs and magnetic resonance imaging demonstrated solid fusion and the complete remission of the initial abscess formation after

    In this study we aimed to develop a simple and practical technique for chronic sacral epidural catheterization of rabbits. We included ten rabbits weighing 2-2.5 kg in the study. After anesthesia and analgesia, we placed an epidural catheter by a 2 cm longitudinal skin incision in the tail above the sacral hiatus region. We confirmed localization by giving 1% lidocaine (leveling sensory loss and motor function loss of the lower extremity). The catheter was carried forward through a subcutaneous tunnel and fixed at the neck. Chronic caudal epidural catheter placement was succesful in all rabbits. The catheters stayed in place effectively for ten days. We encountered no catheter complications during this period. The localization of the catheter was reconfirmed by 1% lidocaine on the last day. After animals killing, we performed a laminectomy and verified localization of the catheter in the epidural space. Various methods for catheterization of the epidural space in animal models exist in the literature. Epidural catheterization of rabbits can be accomplished by atlanto-occipital, lumbar or caudal routes by amputation of the tail. Intrathecal and epidural catheterization techniques defined in the literature necessitate surgical skill and knowledge of surgical procedures like laminectomy and tail amputation. Our technique does not require substantial surgical skill, anatomical integrity is preserved and malposition of the catheter is not encountered. In conclusion, we suggest that our simple and easily applicable new epidural catheterization technique can be used as a model in experimental animal studies.

    We aimed to clarify whether the short-term adverse neonatal outcomes associated with epidural analgesia are due to the epidural analgesia itself or to the instrumental delivery. A retrospective case-control study was conducted to evaluate the relationship between epidural analgesia, labor length, and perinatal outcomes. A total of 350 pregnant women at term who delivered under epidural analgesia (cases) were compared with 1400 patients without epidural analgesia (controls). Vacuum extraction (6.5 vs. 2.9 %) and cesarean section (19.9 vs. 11.1 %) were more frequently performed in the cases than controls (p neonatal variables stratified by mode of delivery were not different in cases and controls, except for a slightly lower umbilical arterial pH in spontaneous delivery for the cases group. However, the Apgar scores and umbilical arterial pH were significantly lower in the neonates delivered by vacuum extraction compared with those in the neonates delivered by spontaneous delivery or cesarean section, regardless of whether epidural analgesia was performed. A multivariable analysis showed that vacuum extraction much more consistently affected the arterial pH than the analgesia itself (the β coefficients were -0.036 for epidural analgesia vs. -0.050 for vacuum extraction). Epidural analgesia was associated with slowly progressing labor, thus resulting in an increased rate of instrumental delivery. This instrumental delivery appears to adversely affect the neonatal outcomes more strongly than the analgesia itself.

    Maternal age is an established risk factor for cesarean section; epidural analgesia and oxytocin augmentation may modify this association. We investigated the effects and interactions of oxytocin augmentation, epidural analgesia and maternal age on the risk of cesarean section. In all, 416 386 nulliparous women with spontaneous onset of labor, ≥37 weeks of gestation and singleton infants with a cephalic presentation during 2000-2011 from Norway and Denmark were included [Ten-group classification system (Robson) group 1]. In this case-control study the main exposure was maternal age; epidural analgesia, oxytocin augmentation, birthweight and time period were explanatory variables. Chi-square test and logistic regression were used to estimate associations and interactions. The cesarean section rate increased consistently with advancing maternal age, both overall and in strata of epidural analgesia and oxytocin augmentation. We observed strong interactions between maternal age, oxytocin augmentation and epidural analgesia for the risk of cesarean section. Women with epidural analgesia generally had a reduced adjusted odds ratio when oxytocin was used compared with when it was not used. In Norway, this applied to all maternal age groups but in Denmark only for women ≥30 years. Among women without epidural, oxytocin augmentation was associated with an increased odds ratio for cesarean section in Denmark, whereas no difference was observed in Norway. Oxytocin augmentation in nulliparous women with epidural analgesia is associated with a reduced risk of cesarean section in labor with spontaneous onset. © 2018 Nordic Federation of Societies of Obstetrics and Gynecology.

    To evaluate the efficacy and tolerability of a clonidine transdermal patch in the treatment of children with tic disorders (TD) and to establish a predictive model for patients. Forty-one patients who met the inclusion criteria entered into 12 weeks of prospective, open, single-group, self-controlled treatment with a clonidine transdermal patch. The Yale Global Tic Severity Scale (YGTSS) was employed before therapy (baseline) and at 4, 8, and 12 weeks after therapy. (1) The total effect rates of treatment with a clonidine transdermal patch were 29.27, 53.66, and 63.41% at 4, 8, and 12 weeks, respectively. Compared with the baseline, the differences were significant at three different observation periods. (2) Compared to the level of 25% reduction, there were significant decreases in the score-reducing rate of motor tic and total tic severities at 12 weeks. (3) If the disease course was ≤24 months and the motor tic score was tic score was >16, there was an effective rate of 57.1%. If the disease course was >24 months and the clinical classification was chronic TD, there was an effective rate of 62.5%. If the disease course was >24 months and the clinical classification was Tourette's syndrome, 90% of the patients were invalid. (4) The main adverse events were rash, slight dizziness, and headache. (1) When patients were pretreated with a D2-dopamine receptor antagonist that was ineffective or not tolerated well, switching to a clonidine transdermal patch treatment was effective and safe. (2) A clonidine transdermal patch could be a first-line medication for mild and moderate TD cases that are characterized by motor tics.

  20. Effects of sevoflurane and clonidine on acid base status and long-term emotional and cognitive outcomes in spontaneously breathing rat pups.

    Full Text Available Numerous experiments in rodents suggest a causative link between exposure to general anaesthetics during brain growth spurt and poor long-lasting neurological outcomes. Many of these studies have been questioned with regard of their translational value, mainly because of extremely long anaesthesia exposure. Therefore, the aim of the present study was to assess the impact of a short sevoflurane anaesthesia, alone or combined with clonidine treatment, on respiratory function in spontaneously breathing rat pups and overall effects on long-lasting emotional and cognitive functions.At postnatal day (PND 7, male Sprague Dawley rat pups were randomized into four groups and exposed to sevoflurane for one hour, to a single dose of intraperitoneal clonidine or to a combination of both and compared to a control group. Blood gas analysis was performed at the end of sevoflurane anaesthesia and after 60 minutes from clonidine or saline injection. Emotional and cognitive outcomes were evaluated in different group of animals at infancy (PND12, adolescence (PND 30-40 and adulthood (PND 70-90.Rat pups exposed to either sevoflurane or to a combination of sevoflurane and clonidine developed severe hypercapnic acidosis, but maintained normal arterial oxygenation. Emotional and cognitive outcomes were not found altered in any of the behavioural task used either at infancy, adolescence or adulthood.Sixty minutes of sevoflurane anaesthesia in newborn rats, either alone or combined with clonidine, caused severe hypercapnic acidosis in spontaneously breathing rat pups, but was devoid of long-term behavioural dysfunctions in the present setting.

    Epidural lumbar fibrosis was induced in eight beagle dogs at the L-6 level. Vascular injection with india ink showed abundant vessels in the scar. This agreed with light microscopy in eight patients with epidural fibrosis, which enhanced with Gd-DTPA from a clinical trial. Electron microscopy of epidural scar in humans and dogs demonstrated a continuous endothelium with scattered tight junctions. Biodistirbution was determined in four dogs with rapid MR scanning following intravenous (IV) bolus of 0.1 mmol/kg of Gd-DTPA and radioassay of tissue samples following Gd-153-DTPA IV injection. Maximum percent enhancement (70% humans, 100% dogs) occurred at 3-6 minutes in epidural fibrosis with a slow decline in enhancement over the next hour. These findings suggest that Gd-DTPA enhancement of epidural fibrosis is via an extracellular distribution within vascularized scar tissue

    We present the case of a 78-year-old woman with a spontaneous spinal epidural hematoma that presented with sudden interscapular pain accompanied by left hemiparesis and a significant improvement 15 minutes later. Initially diagnosed as angina, the persistence of pain in dorsal cervical spine suggested the need to perform magnetic resonance imaging (MRI). The images demonstrated a lesion in the epidural spinal canal at level C3-D2 that presented a heterogeneous signal intensity, with hyperintense areas in T1-weighted sequences and hypointense areas in gradient-echo sequences, with no sign of compression myelopathy. A diagnosis of epidural hematoma was established and, given the favorable clinical course, conservative treatment was indicated. The second MRI study showed the complete resorption of the epidural hematoma. (Author) 12 refs.

    2012-02-01

    BACKGROUND AND OBJECTIVE: The last 25 years have seen changes in the management of epidural analgesia for labour, including the advent of low-dose epidural analgesia, the development of new local anaesthetic agents, various regimes for maintaining epidural analgesia and the practice of combined spinal-epidural analgesia. We conducted a survey of Irish obstetric anaesthetists to obtain information regarding the conduct and management of obstetric epidural analgesia in Ireland in 2005. The specific objective of this survey was to discover whether new developments in obstetric anaesthesia have been incorporated into clinical practice. METHODS: A postal survey was sent to all anaesthetists with a clinical commitment for obstetric anaesthesia in the sites approved for training by the College of Anaesthetists, Ireland. RESULTS: Fifty-three per cent of anaesthetists surveyed responded. The majority of anaesthetists (98%) use low-dose epidural analgesia for the maintenance of analgesia. Only 11% use it for test-dosing and 32% for the induction of analgesia. The combined spinal-epidural analgesia method is used by 49%, but two-thirds of those who use it perform fewer than five per month. Patient-controlled epidural analgesia was in use at only one site. CONCLUSION: It appears that Irish obstetric anaesthetists have adopted the low-dose epidural analgesia trend for the maintenance of labour analgesia. This practice is not as widespread, however, for test dosing, the induction of analgesia dose or in the administration of intermittent epidural boluses to maintain analgesia when higher concentrations are used. Since its introduction in 2000, levobupivacaine has become the most popular local anaesthetic agent.

    OBJECTIVES: To examine the association of intrapartum temperature elevation with adverse neonatal outcome among low-risk women receiving epidural analgesia and evaluate the association of epidural with adverse neonatal outcome without temperature elevation. METHODS: We studied all low-risk nulliparous women with singleton pregnancies ≥37 weeks delivering at our hospital during 2000, excluding pregnancies where infants had documented sepsis, meningitis, or a major congenital anomaly. Neonatal outcomes were compared between women receiving (n = 1538) and not receiving epidural analgesia (n = 363) in the absence of intrapartum temperature elevation (≤99.5°F) and according to the level of intrapartum temperature elevation within the group receiving epidural (n = 2784). Logistic regression was used to evaluate neonatal outcome while controlling for confounders. RESULTS: Maternal temperature >100.4°F developed during labor in 19.2% (535/2784) of women receiving epidural compared with 2.4% (10/425) not receiving epidural. In the absence of intrapartum temperature elevation (≤99.5°F), no significant differences were observed in adverse neonatal outcomes between women receiving and not receiving epidural. Among women receiving epidural, a significant linear trend was observed between maximum maternal temperature and all neonatal outcomes examined including hypotonia, assisted ventilation, 1- and 5-min Apgar scores 101°F had a two- to sixfold increased risk of all adverse outcomes examined. CONCLUSIONS: The proportion of infants experiencing adverse outcomes increased with the degree of epidural-related maternal temperature elevation. Epidural use without temperature elevation was not associated with any of the adverse outcomes we studied. PMID:22291120

    Currently, no gold standard method exists for localization of an epidural catheter after placement. The technique described in this report uses pulsed-wave Doppler (PWD) ultrasound to identify intrathecal location of an epidural catheter. A thoracic epidural catheter was inserted after multiple trials with inconclusive aspiration and test dose. Ultrasound PWD confirmed no flow in the epidural space and positive flow in the intrathecal space. A fluid aspirate was positive for glucose, reconfirming intrathecal placement. PWD is a potential tool that can be used to locate the tip of an epidural catheter.

    Six patients with acquired spinal subarachnoid cysts secondary to epidural anesthesia were evaluated with MR imaging (seven patients) and intraoperative US (three patients). The cysts were located in the lower cervical and thoracic spine. Adhesions and irregularity of the cord surface were frequently noted. Associated intramedullary lesions, including intramedullary cysts and myelomalacia, were seen in two of the patients. Arachnoiditis was unsuspected clinically in three patients, and MR imaging proved to be the diagnostic examination that first suggested the cause of the patients symptoms. The underlying mechanism for the formation of these cysts is a chemically induced arachnoiditis

    In situ saphenous vein arterial bypass flow was studied in 16 patients with respect to level of epidural anaesthesia. Arterial pressure and electromagnetic flow were used to evaluate arterial tone by intra-arterial (i.a.) papaverine. Eight patients had a low epidural block (... patients were operated during high epidural anaesthesia (> Th. 10). Flow increased and arterial pressure decreased after i.a. papaverine in all patients. When compared with patients operated during high epidural anaesthesia, flow increase and decrease in vascular resistance took place in patients operated...... during low epidural anaesthesia (P i.a. papaverine was not significantly different in patients operated in low epidural and general anaesthesia (n = 8). In eight patients with insulin-dependent diabetes mellitus who had low epidural anaesthesia, the increase...

    Social media as YouTube have become a part of daily life and many studies evaluated health-related YouTube videos. Our aim was to evaluate videos available on YouTube for the conformity to textbook information and their sufficiency as a source for patient information. A search of the YouTube website was performed using the keywords "spinal anesthesia, epidural anesthesia, combined spinal epidural anesthesia". Firstly, 180 videos were evaluated and the characteristics of the video were noted, and the features of the video too were noted if the video was regarding neuraxial anesthesia. Questionnaire 1 (Q1) evaluating the video quality relating to neuraxial anesthesia was designed using a textbook as reference and questionnaire 2 (Q2) was designed for evaluating patient information. After exclusions, 40 videos were included in the study. There was no difference in Q1 or Q2 scores when videos were grouped into 4 quarters according to their appearance order, time since upload or views to length rate (p>0.05). There was no statistical difference between Q1 or Q2 scores for spinal, epidural or combined videos (p>0.05). Videos prepared by a healthcare institute have a higher score in both Questionnaires 1 and 2 (10.87±4.28 vs. 5.84±2.90, p=0.044 and 3.89±5.43 vs. 1.19±3.35, p=0.01 respectively). Videos prepared by institutes, societies, etc. were of higher educational value, but were still very lacking. Videos should be prepared in adherence to available and up-to-date guidelines taking into consideration appropriate step by step explanation of each procedure, patient safety and frequently asked questions.

    Transsphenoidal approach to pituitary tumors is a commonly performed procedure with the advantage of a rapid midline access to the sella with minimal complications. It may be associated with wide fluctuations in hemodynamic parameters due to intense noxious stimulus at various stages of the surgery. As duration of the surgery is short and the patients have nasal packs, it is prudent to use an anesthestic technique with an early predictable recovery. A total of 60 patients of either sex between 18 and 65 years of age, belonging to the American Society of Anesthesiologists I and II who were undergoing elective transnasal transsphenoidal pituitary surgery were chosen for this study. Patients were randomly allocated into two groups, Group C (clonidine) and Group D (dexmedetomidine), with each group consisting of 30 patients. Patients in Group C received 200 μg tablet of clonidine and those in Group D received a pantoprazole tablet as placebo at the same time. Patients in the Group D received an intravenous infusion of dexmedetomidine diluted in 50 ml saline (200 μg in 50 ml saline) 10 min before induction and patients in Group C received 0.9% normal saline (50 ml) as placebo. The hemodynamic variables (heart rate, mean arterial pressure) were noted at various stages of the surgery. Statistical analysis of the data was performed. A total of 60 patients were recruited. The mean age, sex, weight and duration of surgery among the two groups were comparable ( P > 0.05). Both dexmedetomidine and clonidine failed to blunt the increase in hemodynamic responses (heart rate and blood pressure) during intubation, nasal packing, speculum insertion and extubation. However when the hemodynamic response was compared between the patients receiving dexmedetomidine and clonidine it was seen that patients who received dexmedetomidine had a lesser increase in heart rate and blood pressure ( P < 0.05) when compared to clonidine. A continuous intravenous infusion of dexmedetomidine as

    Full Text Available Background: Hemodynamic changes induced by labor pain and apprehension in addition to physiological changes may pose risk to parturients with rheumatic heart disease (RHD. Therefore, it is important to provide adequate pain relief during labor in these patients. We planned this study to compare the efficacy and safety of epidural (E versus combined spinal - epidural (CSE for labor analgesia in parturients with rheumatic valvular heart disease. Methods: Twenty-five parturients with RHD included in this study were randomized to one of the two groups - E group (n = 12, received 6 mL of 0.0625% bupivacaine with 25 μg fentanyl or CSE group (n = 13, received 25 μg of fentanyl with 1.25 mg bupivacaine diluted to 1 mL in subarachnoid space. Afterward, a continuous infusion of 0.1% bupivacaine with 2 μg/mL fentanyl was started at 6-8 mL/h. Primary outcome, analgesic efficacy, was assessed by visual analog scale (VAS for pain. VAS ≤ 3 was considered as effective analgesia. Rescue analgesia in the form of epidural bolus was given if VAS > 3. Results: Demographic characteristics of the patients were comparable. Mitral stenosis was the predominant valvular lesion. The VAS at which the parturients received analgesia was comparable. The mean time to achieve effective analgesia was significantly faster in CSE group (4.46 ± 0.87 min compared with group E (15.09 ± 5.7 min (P < 0.001. Significantly lower median pain scores were recorded until the initial 15 min in CSE group. Afterward, median VAS for pain was comparable between the groups. VAS for pain was significantly low at all time intervals than baseline in both the groups. Maternal satisfaction and incidence of cesarean rate and complication were comparable between the groups. Conclusion: Both epidural and CSE are equally effective and safe for labor analgesia in parturients with rheumatic valvular heart disease. However, CSE technique provides a faster onset of analgesia.

    The spring-loaded syringe is a loss of resistance syringe that provide a more objective sign that the epidural space has been entered compared with the traditional techniques. The aim of this study was to compare the time required to locate the epidural space and the backache incidence with the spring-loaded (SL), loss of resistance (LOR) and the hanging drop (HD) techniques for epidural blocks in patients undergoing transurethral resection procedure. Sixty patients undergoing transurethral resections were enrolled in the study. The patients were randomly assigned to one of three groups. Epidural block was performed in the first group with a spring-loaded syringe (n=20), in the second group with loss-of-resistance syringe (n=20), and in the third group with the hanging drop technique (n=20). The required time to locate the epidural space, the number of attempts, the incidence of dural puncture and the backache incidence were assessed during the procedure and for four weeks after the procedure in all patients. The required time to locate the epidural space was 29.1 ± 9.16 seconds in Group 1; 45.25 ± 19.58 seconds in Group 2, and 47.35 ± 11.42 seconds in Group 3 (p0.05). The use of SL syringe was found to have a shorter time period to locate the epidural space when compared with the LOR syringe and hanging drop technique.

    Full Text Available We report three cases of spontaneous spinal epidural hematoma (SSEH with hemiparesis. The first patient was a 73-year-old woman who presented with left hemiparesis, neck pain, and left shoulder pain. A cervical MRI scan revealed a left posterolateral epidural hematoma at the C3–C6 level. The condition of the patient improved after laminectomy and evacuation of the epidural hematoma. The second patient was a 62-year-old man who presented with right hemiparesis and neck pain. A cervical MRI scan revealed a right posterolateral dominant epidural hematoma at the C6-T1 level. The condition of the patient improved after laminectomy and evacuation of the epidural hematoma. The third patient was a 60-year-old woman who presented with left hemiparesis and neck pain. A cervical MRI scan revealed a left posterolateral epidural hematoma at the C2–C4 level. The condition of the patient improved with conservative treatment. The classical clinical presentation of SSEH is acute onset of severe irradiating back pain followed by progression to paralysis, whereas SSEH with hemiparesis is less common. Our cases suggest that acute cervical spinal epidural hematoma should be considered as a differential diagnosis in patients presenting with clinical symptoms of sudden neck pain and radicular pain with progression to hemiparesis.

    To explore relationships between maternal epidural analgesia and two measures of neurobehavioral organization in infants at the initial feeding 1 hour after birth. Prospective comparative design. Inner-city community hospital, Chicago, Illinois. Convenience sample of 52 low-risk, mainly Black and Latino, mother/infant dyads. Mothers self-selected to labor with epidural or no labor pain medication. Neonatal neurobehavioral organization was measured in term infants at the initial feeding 1 hour after birth. A nutritive sucking apparatus generated data on total number of sucks and sucking pressure. Video recordings of infants (before and after the initial feeding) were coded for behavioral states, with analysis on frequency of alertness. Total number of sucks and sucking pressure were not related to epidural exposure, although an epidural drug dosage effect on total number of sucks was evident when gender was a factor. Unmedicated girls demonstrated more sucks than girls in the high-dosage epidural group (p=.027). Overall, girls exhibited stronger sucking pressure than boys (p=.042). Frequency of alertness was not related to epidural exposure, although longer labor was related to greater alertness (p=.003), and Latino infants were more alert than Black infants (p=.002). Results suggest attenuated neonatal nutritive sucking organization in girls after exposure to high maternal epidural dosages. In comparison to boys, girls may have enhanced neurobehavioral organization at birth. Race/ethnicity and alertness may have spurious associations in which hidden factors drive the relationship.

    Treatment for rib fracture pain can be broadly divided into pharmacologic approaches with oral and/or parenteral medication and interventional approaches utilizing neuraxial analgesia or peripheral nerve blocks to provide pain relief. Both approaches attempt to control nociceptive and neuropathic pain secondary to osseous injury and nerve insult, respectively. Success of treatment is ultimately measured by the ability of the selected modality to decrease pain, chest splinting, and to prevent sequelae of injury, such as pneumonia. Typically, opioids and NSAIDs are the drugs of first choice for acute pain because of ease of administration, immediate onset of action, and rapid titration to effect. In contrast, neuropathic pain medications have a slower onset of action and are more difficult to titrate to therapeutic effect. Interventional approaches include interpleural catheters, intercostal nerve blocks, paravertebral nerve blocks, and thoracic and lumbar epidural catheters. Each intervention has its own inherent advantages, disadvantages, and success rates. Rib fracture pain management practice is founded on the thoracic surgical and anesthesiology literature. Articles addressing rib fracture pain are relatively scarce in the pain medicine literature. As life expectancy increases, and as healthcare system modifications are implemented, pain medicine physicians may be consulted to treat increasing number of patients suffering rib fracture pain and may need to resort to novel therapeutic measures because of financial constraints imposed by those changes. Here we present the first published case series of thoracic epidural steroid injections used for management of rib fracture pain. © 2012 The Authors Pain Practice © 2012 World Institute of Pain.

    Full Text Available The authors present two cases of intraventricular hemorrhage (IVH believed to be a result of epidural blood patching. The first was a 71-year-old woman who had new onset of nontraumatic IVH on computed tomography (CT scan after undergoing an epidural blood patch (EBP. This amount of intraventricular blood was deemed an incidental finding since it was of very small volume to account for her overall symptoms. The second patient, a 29-year-old woman, was found to have nontraumatic IVH three days after undergoing an EBP. This was seen on CT scan of the head for workup of pressure-like headaches, nausea, vomiting, and absence seizures. Conservative management was followed in both instances. Serial CT scan of the head in our first patient displayed complete resolution of her IVH. The second patient did not have follow-up CT scans because her overall clinical picture had improved significantly. This highlights a potential sequel of EBP that may be observed on CT scan of the head. In the event that IVH is detected, signs and symptoms of hydrocephalus should be closely monitored with the consideration for a future workup if warranted by the clinical picture.

    To explore whether epidural analgesia (EA) in labor is independent risk factor for neonatal pyrexia after controlling for intrapartum pyrexia. Retrospective observational study of 480 consecutive term singleton infants born to mothers who received EA in labor (EA group) and 480 term infants delivered to mothers who did not receive EA (NEA group). Mothers in the EA group had significantly higher incidence of intrapartum pyrexia [54/480 (11%) vs. 4/480 (0.8%), OR = 15.1, p neonatal pyrexia [68/480 (14.2%) vs. 15/480 (3.1%), OR = 5.1, p Neonates in the EA group had a median duration of pyrexia of 1 h (maximum 5 h) with a peak temperature within 1 h. Stepwise logistic regression analysis showed that maternal EA was independent risk factor for neonatal pyrexia (>37.5°C) after controlling for intrapartum pyrexia (>37.9°C) and other confounders (OR = 3.44, CI = 1.9-6.3, p neonates. It is unnecessary to investigate febrile offspring of mothers who have had epidurals unless pyrexia persists for longer than 5 h or other signs or risk factors for neonatal sepsis are present.

    Full Text Available BACKGROUND AND OBJECTIVES: In this study, we aimed to clarify the importance of residency grade and other factors which influence the success of thoracic epidural catheterization in thoracotomy patients. METHODS: After the ethical committee approval, data were recorded retrospectively from the charts of 415 patients. All patients had given written informed consent. The thoracic epidural catheterization attempts were divided into two groups as second-third year (Group I and fourth year (Group II according to residency grade. We retrospectively collected demographic data, characteristics of thoracic epidural catheterization attempts, and all difficulties and complications during thoracic epidural catheterization. RESULTS: Overall success rate of thoracic epidural catheterization was similar between the groups. Levels of catheter placement, number and duration of thoracic epidural catheterization attempts were not different between the groups (p > 0.05. Change of needle insertion level was statistically higher in Group II (p = 0.008, whereas paresthesia was significantly higher in Group I (p = 0.007. Dural puncture and postdural puncture headache rates were higher in Group I. Higher body mass index and level of the insertion site were significant factors for thoracic epidural catheterization failure and postoperative complication rate and those were independence from residents' experience (p < 0.001, 0.005. CONCLUSION: Body mass index and level of insertion site were significant on thoracic epidural catheterization failure and postoperative complication rate. We think that residents' grade is not a significant factor in terms overall success rate of thoracic epidural catheterization, but it is important for outcome of these procedures.

    Posterior epidural lumbar disc fragment is infrequent because of anatomical barriers, and it is difficult to diagnose posterior epidural lumbar disc fragment because of its rare incidence and the ambiguity of radiologic evaluations. And it is difficult to differentiate it from other diseases such as spinal tumors. Differential diagnosis of posterior epidural lumbar disc fragment is clinically important because its diagnosis can affect treatment and prognosis. To investigate the incidence, anatomical concern, etiology, symptom, diagnostic tool, management and prognosis of posterior epidural lumbar disc fragment, we reviewed articles including case report. We performed a search of all clinical studies of posterior epidural lumbar disc fragment published to date. The following keywords were searched: Posterior epidural lumbar disc fragment, disc migration, posterior epidural disc, extradural migration, dorsal epidural migration, sequestrated disc, and disc fragment. We identified 40 patients of posterior epidural lumbar disc fragment from 28 studies. The most common presentation of posterior epidural lumbar disc fragment was sudden onset radiculopathy (70.0%), followed by cauda equina syndrome (27.5%). The most frequently used diagnostic modality was magnetic resonance imaging (MRI), conducted in 36 cases (90.0%), and followed by computed tomography in 14 cases (35.0%). After the imaging studies, the preoperative diagnoses were 45.0% masses, 20.0% lesions, and 12.5% tumors. Characteristic MRI findings in posterior epidural lumbar disc fragment are helpful for diagnosis; it typically displays low signals on T1-weighted images and high signals on T2-weighted images with respect to the parent disc. In addition, most of the disc fragments show peripheral rim enhancement on MRI with gadolinium administration. Electrodiagnostic testing is useful for verifying nerve damage. Surgical treatment was performed in all cases, and neurologic complications were observed in 12.5%. As

    Report of an uncommon complication of acupuncture and wet cupping. A 54-year-old man presented with neck pain and fever. Magnetic resonance imaging of the cervical spine revealed an epidural abscess at C4 to T2. The symptoms related to epidural abscess resolved partially after treatment with antibiotics. Acupuncture and wet-cupping therapy should be taken into consideration as a cause of spinal epidural abscesses in patients who present with neck pain and fever. Furthermore, acupuncture and wet-cupping practitioners should pay attention to hygienic measures. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Spinal epidural hematomas are rare pathology, caused by trauma or spontaneous. In clinical examination acute spinal cord compression is observed. MRI designations appear entirely particular. In sagittal projection, biconvex mass in the dorsal, or sometimes ventral part of the spinal canal is clearly visible. This is well delineated by the thecal sac from the cord and cauda equina. MRI investigations in 3 patients revealed corresponding with spinal bone injuries and cord edema epidural hematomas. Differential diagnosis must contain subdural hematoma and epidural neoplasms or abscess. (author) 8 refs, 3 figs

    Full Text Available Anesthesia in a dwarf patient may be challenging as various anatomical anomalies make both general and regional anesthesia difficult. These patients may have atlantoaxial instability, potential for airway obstruction, and associated respiratory problems that may pose problems for general anesthesia. Spinal stenosis, osteophytes, short pedicles, or a small epidural space could complicate regional anesthesia in dwarfs which could lead to difficulties in locating the epidural space and increase the risk of dural puncture. Spinal stenosis may impair cerebrospinal fluid flow such that identification of dural puncture is difficult. This elderly dwarf patient had history of bronchial asthma with restriction of neck extension, managed successfully using combined spinal–epidural anesthesia.

    Cholinergic agonists produce spinal antinociception via mechanisms involving an increased release of intraspinal acetylcholine. The cholinergic receptor system interacts with several other receptor types, such as alpha2-adrenergic receptors. To fully understand these interactions, the effects...... of various receptor ligands on the cholinergic system must be investigated in detail. This study was initiated to investigate the effects of the alpha2-adrenergic receptor agonists clonidine and rilmenidine and the alpha2-adrenergic receptor antagonists yohimbine and efaroxan on spinal cholinergic receptors......, all ligands possessed affinity for nicotinic receptors. Clonidine and yohimbine binding was best fit to a one site binding curve and rilmenidine and efaroxan to a two site binding curve.

    Background Ropivacaine and levobupivacaine have been introduced into obstetric analgesic practice with the proposed advantages of causing less motor block and toxicity compared with bupivacaine. However, it is still controversial whether both anesthetics are associated with any clinical benefit relative to bupivacaine for labor analgesia. This study aimed to compare the analgesic efficacy, motor block and side effects of bupivacaine, ropivacaine and levobupivacaine at lower concentrations for patient-controlled epidural labor analgesia. Methods Four hundred and fifty nulliparous parturients were enrolled in this randomized clinical trial. A concentration of 0.05%, 0.075%, 0.1%, 0.125% or 0.15% of either bupivacaine (Group B), ropivacaine (Group R) or levobupivacaine (Group L) with sufentanil 0.5 μg/ml was epidurally administered by patient-controlled analgesia mode. Effective analgesia was defined as a visual analogue scale score was ≤30 mm. The relative median potency for each local anesthetic was calculated using a probit regression model. Parturients demographics, sensory and motor blockade, obstetric data, maternal side effects, hourly volumes of local anesthetic used, and others were also noted. Results There were no significant differences among groups in the numbers of effective analgesia, pain scores, hourly local anesthetic amount used, sensory and motor blockade, labor duration and mode of delivery, side effects and maternal satisfaction (P >0.05). The relative median potency was bupivacaine/ropivacaine: 0.828 (0.602-1.091), bupivacaine/levobupivacaine: 0.845 (0.617-1.12), ropivacaine/levobupivacaine: 1.021 (0.774-1.354), respectively. However, a significantly less number of effective analgesia and higher hourly local anesthetic use were observed in the concentration of 0.05% than those of ≥0.1% within each group (P<0.05). Conclusions Using patient-controlled epidural analgesia, lower concentrations of bupivacaine, ropivacaine and levobupivacaine

    Full Text Available Background: This study was designed to evaluate the postoperative analgesic efficacy of levobupivacaine (L alone and its combination with clonidine (C or dexmedetomidine (D in wound infiltration technique for abdominal surgeries. Materials and Methods: After ethical committee approval, a double-blind randomized controlled study was conducted on 90 patients (power of study 80%, physical status American Society of Anesthesiologists Grade I and II, aged 18–60 years scheduled for abdominal surgeries over 1 year duration. A standard general anesthetic technique was used. Patients were randomly allocated into three groups, by computer-generated random number table. Patients received wound infiltration during wound closure. Group L received 29 ml of 0.25% levobupivacaine plus 1 ml 0.9% normal saline, Group LC received 29 ml of 0.25% levobupivacaine with 1 ml (3 mcg/kg clonidine, and Group LD received 29 ml of 0.25% levobupivacaine with 1 ml (2 mcg/kg dexmedetomidine. Postoperative rescue analgesia was provided with injection tramadol. Statistical analysis for duration of analgesia was determined by one-way analysis of variance and side effects by Chi-square test. Results: The total duration of analgesia in LD group was 23.4 h, when compared to LC group 20.9 h and L group 11.65 h (P = 0.0001 with excellent to good quality of analgesia in adjuvant group (P < 0.001 and incidence of minimal side effects such as sedation, nausea, and vomiting. Conclusion: Clonidine and dexmedetomidine were the effective adjuvants to levobupivacaine for single shot wound infiltration analgesic technique; however, dexmedetomidine was found to be superior to clonidine.

    To compare the efficacy of clonidine versus phenobarbital in reducing morphine sulfate treatment days for neonatal abstinence syndrome (NAS). Prospective, non-blinded, block randomized trial at a single level III NICU (Neonatal Intensive Care Unit). Eligible infants were treated with a combination of medications as per protocol. Primary outcome was treatment days with morphine sulfate. Secondary outcomes were the mean total morphine sulfate dose, outpatient phenobarbital days, adverse events and treatment failures. A total of 82 infants were eligible, of which 68 were randomized with 34 infants in each study group. Adjusting for covariates phenobarbital as compared with clonidine had shorter morphine sulfate treatment days (-4.6, 95% confidence interval (CI): -0.3, -8.9; P=0.037) with no difference in average morphine sulfate total dose (1.1 mg kg(-1), 95% CI: -0.1, 2.4; P=0.069). Post-discharge phenobarbital was continued for an average of 3.8 months (range 1 to 8 months). No other significant differences were noted. Phenobarbital as adjunct had clinically nonsignificant shorter inpatient but significant overall longer therapy time as compared with clonidine.

    To analyze the benefits of external cephalic version (ECV) with epidural analgesia at term and labor induction just after the procedure. This is a retrospective observational study with patients who did not want trying a breech vaginal delivery and decided trying an ECV with epidural analgesia at term and wanted labor induction or cesarean section after the procedure. We present the results of 40 ECV with epidural analgesia at term and labor induction or cesarean section just after the ECV. ECV succeeded in 26 out of 40 (65%) patients. Among the 26 successful ECV, 6 delivered by cesarean (23.1%). 20 patients delivered vaginally (76.9%; 50% of all patients). Considering that a high number of cesarean deliveries can be avoided, induction of labor after ECV with epidural analgesia at term can be considered after being discussed in selected patient.

    Spontaneous spinal epidural haematoma (SSEH) is a rare cause of neurological deficit in the pregnant and post-partum patients. However, SSEH with associated myelitis presenting as quadriplegia and respiratory paralysis in the post-partum period has never been reported. We report the development of acute onset quadriplegia progressing to respiratory arrest in a 24-yr-old woman 2 weeks after normal vaginal delivery. There was no history suggestive of any coagulopathy (inherited or acquired), eclampsia, pre-existing neurological deficit, or iatrogenic manipulations such as spinal/epidural injections. Magnetic resonance imaging revealed a posterior epidural haematoma extending from C4-C7 and areas of signal changes in spinal cord from cervicomedullary junction to D5 level (suggestive of demyelination). We highlight this rare cause of quadriplegia; focusing on the altered dynamics of the epidural vasculature in the peripartum period leading to SSEH.

    We present the case of a 78-year-old woman with a spontaneous spinal epidural hematoma that presented with sudden interscapular pain accompanied by left hemiparesis and a significant improvement 15 minutes later. Initially diagnosed as angina, the persistence of pain in dorsal cervical spine suggested the need to perform magnetic resonance imaging (MRI). The images demonstrated a lesion in the epidural spinal canal at level C3-D2 that presented a heterogeneous signal intensity, with hyperintense areas in T1-weighted sequences and hypointense areas in gradient-echo sequences, with no sign of compression myelopathy. A diagnosis of epidural hematoma was established and, given the favorable clinical course, conservative treatment was indicated. The second MRI study showed the complete resorption of the epidural hematoma. (Author) 12 refs

    To evaluate skin temperature increase as an early predictive measure for evaluating epidural and femoral-sciatic block success in dogs. Prospective clinical trial. A total of 29 dogs undergoing orthopaedic surgery on one hindlimb. Dogs were anaesthetized and placed into lateral recumbency with the affected limb uppermost and the coat was clipped. Baseline infrared thermographic images (T0) of the affected limb, of the paw pad of the affected leg and of the ipsilateral paw pad were taken. Subsequently, dogs were administered either an epidural (EPI; n=11) or a femoral-sciatic block (FS; n=18) using bupivacaine 1 mg kg -1 . Then, 2 minutes after placement of the block, thermographic images were obtained every 3 minutes for a total of four measurements (T1-T4) and surgery was commenced. Rescue analgesia consisting of fentanyl 1 μg kg -1 was administered if needed. A regional block was considered successful if the dose of fentanyl administered was less than the lower 95% confidence interval of the geometric mean of the total fentanyl used in each group. A ≥ 1 °C increase of skin temperature was considered as the minimum increase required for detection of a successful block. A total of 12 out of 18 blocks in the FS and eight of 11 in the EPI group were considered successful based on fentanyl consumption. Out of these, only four of 12 in the FS and one of eight in the EPI group developed an increase in temperature of ≥ 1 °C. Contrarily, four of six of the nonsuccessful cases in the FS and three of three in the EPI group developed an increase in temperature of ≥ 1 °C. Contrary to reports in humans, thermography did not indicate regional block success prior to surgery in dogs. However further studies under more controlled conditions are needed to determine whether thermography can be used to indicate failure of regional blockade.

    1992-09-01

    Epidural lipomatosis is a rare condition in which overgrowth of extradural fat can lead to back pain, spinal cord compression and radiculopathy. A 51-year-old man developed back pain and reduced mobility following a standard course of radiotherapy for a Stage I seminoma. His symptoms and radiological appearances were initially attributed to radiation fibrosis. Further investigations and operative intervention revealed epidural lipomatosis. The excess lipomatous tissue was removed with complete resolution of his symptoms.

  16. Epidural versus intravenous fentanyl for postoperative analgesia following orthopedic surgery: randomized controlled trial

    Directory of Open Access Journals (Sweden)

    Marcelo Soares Privado

    Full Text Available CONTEXT AND OBJECTIVE: Controversy exists regarding the site of action of fentanyl after epidural injection. The objective of this investigation was to compare the efficacy of epidural and intravenous fentanyl for orthopedic surgery. DESIGN AND SETTING: A randomized double-blind study was performed in Hospital São Paulo. METHODS: During the postoperative period, in the presence of pain, 29 patients were divided into two groups: group 1 (n = 14 received 100 µg of fentanyl epidurally and 2 ml of saline intravenously; group 2 (n = 15 received 5 ml of saline epidurally and 100 µg of fentanyl intravenously. The analgesic supplementation consisted of 40 mg of tenoxicam intravenously and, if necessary, 5 ml of 0.25% bupivacaine epidurally. Pain intensity was evaluated on a numerical scale and plasma concentrations of fentanyl were measured simultaneously. RESULTS: The percentage of patients who required supplementary analgesia with tenoxicam was lower in group 1 (71.4% than in group 2 (100%: 95% confidence interval (CI = 0.001-0.4360 (P = 0.001, Fisher's exact test; relative risk, RR = 0.07. Epidural bupivacaine supplementation was also lower in group 1 (14.3% than in group 2 (53.3%: 95% CI = 0.06-1.05 (P = 0.03, Fisher's exact test; RR = 0.26. There was no difference in pain intensity on the numerical scale. Mean fentanyl plasma concentrations were similar in the two groups. CONCLUSION: Intravenous and epidural fentanyl appear to have similar efficacy for reducing pain according to the numerical scale, but supplementary analgesia was needed less frequently when epidural fentanyl was used.

The study protocol was designed as:Ist group: Coming after the epidural catheter installation, unilateral spinal anesthesia was applied (n=20.IInd group: At first, unilateral spinal anesthesia was applied and after one minute, epidural top-up was done via the pre-installed epidural catheter (n=20.IIIrd group: At first the epidural catheter was installed and epidural top-up was applied. After one minute, unilateral spinal anesthesia was fulfilled (n=2O. Starting from the pre-anesthesic period, the hemodynamic data and following the anesthesia, the sensorial and motor block levels were recorded and evaluated.As the outcome of the inter-groups comparison of heart rate and mean arterial pressure, a statistically note-worthy differance was not determined; statistically significant but clinically acceptable hemodynamic changes were observed in intra-group evaluations, when the data was compared with control levels. The sensorial block levels were significantly higher in group II and significantly lower in group III.The application of 10 mL saline via epidural catheter 1 minute after the unilateral spinal anesthesia and remaining the patient leaning on the side of the extremity to be operated for 15 minutes improves the sensory block level of unilateral spinal anesthesia. It is determined that, for the lower extremity surgical operations with 1-1.5 hour estimated period, this method alone can be a worthwhile alternative.

    BACKGROUND: Traumatic rib fractures are a common condition associated with considerable morbidity and mortality. Observational studies have suggested improved outcome in patients receiving continuous epidural analgesia (CEA). The aim of the present systematic review of randomised controlled trials...... (RCTs) was to assess the benefit and harm of CEA compared with other analgesic interventions in patients with traumatic rib fractures. METHODS: We performed a systematic review with meta-analysis and trial sequential analysis (TSA). Eligible trials were RCTs comparing CEA with other analgesic...... interventions in patients with traumatic rib fractures. Cumulative relative risks (RRs) and mean differences (MDs) with 95% confidence intervals (CIs) were estimated, and risk of systematic and random errors was assessed. The predefined primary outcome measures were mortality, pneumonia and duration...

    2013-01-01

    Background: Delayed epidural hematoma (EDH) is an uncommon finding in patients after intracranial hematomas evacuation. It occurs in 6.7-7.4% of cases. A total of 29 reports were found in literature. Between them were no cases of delayed contralateral EDH after intracerebral hematoma evacuation. Case Description: This paper represents a clinical case of a 28-year-old male patient with opened penetrating head injury, who underwent left frontal lobe intracerebral hematoma evacuation and one day later a contralateral EDH was found and successfully surgically treated. Conclusion: Contralateral EDH is a life-threatening neurosurgical emergency case, which can occur during first 24 hours after decompressive craniectomy. Control CT scans must be performed next day after the operation to verify and treat contralateral EDH timely. PMID:24233058

    Cutaneous fistula of cerebrospinal fluid is a rare complication of neuroaxial blockade. We report the case of a parturient in whom an epidural catheter was placed for labour analgesia and 12h after the catheter was removed, presented an abundant asymptomatic fluid leak from the puncture site, compatible in the cyto-chemical analysis with cerebrospinal fluid. She was treated with acetazolamide, compression of skin orifice of the fluid leakage, antibiotic prophylaxis, hydration and rest, and progressed satisfactorily without requiring blood patch.

    Summary A young patient with a facial trauma after a road accident was admitted to our department with incoercible epistaxis. A CT scan showed a right pterional acute epidural hematoma (EDH). Angiography demonstrated multiple sources of bleeding of the right sphenopalatine arteries, cause of the epistaxis, and an intracranial leakage of the right middle meningeal artery, responsible for the EDH. The patient immediately underwent embolization of the right internal maxillary artery and right middle meningeal artery. The procedure stopped the epistaxis and no further enlargement of the EDH was observed, avoiding its surgical treatment. Endovascular surgery may be an effective procedure to stop the arterial meningeal bleeding sustaining acute EDH and may be a useful tool in the management of special cases of post traumatic EDH.

    Current fashion in body art includes low back tattoos of varying designs and colors, a trend that presents unique concerns for anesthesia providers. Does the placement of epidural catheters risk the introduction of tattoo pigment dyes into the epidural space through the process of coring? Are there specific risks associated with tattoo dyes and epidural needle placement? We performed a comprehensive review of the literature using multiple search databases with the intent to form guidelines for practice using a level of evidence taxonomy. The available evidence does not identify any specific risks associated with epidural catheter placement through low back tattoos, although tissue coring with tissue transport to deeper sites has been confirmed. Continued investigation is necessary before comprehensive practice guidelines regarding the practice of placing epidural needles and catheters through lumbar tattoos can be developed. We suggest avoidance of piercing tattoos when performing epidural punctures until there is sound evidence of short-term and long-term safety.

    Full Text Available The authors present a rare case of calcified (ossified chronic epidural hematoma developed in a six-and-a-half-year-old female patient who was operated for cerebellar astrocytoma 6 months earlier. There was no history of trauma. Ossified epidural hematoma was seen as an incidental finding in the follow-up in computed tomography scan after 6 months of primary glioma surgery. Ossified chronic epidural hematoma with thick collagenous wall and newly formed bone on dura was excised. The development of calcified chronic subdural hematoma after decompressive intracranial surgery is a well-known occurrence, but the fact that a calcified epidural hematoma, which is rare and which can also develop after decompressive surgery, and the occurrence of calcified (ossified epidural hematoma after postfossa a glioma surgery is not yet reported. The second case is a 9-year-old male anemic child with a history of fall while playing 5 months earlier who presented with headache of 3 months duration. He had bifrontal calcified epidural hematoma operated by craniotomy and excision of calcified dural edge.

    Some anesthesiologists contend that intrathecal opioid administration has advantages over conventional epidural techniques during labor. Randomized clinical trials comparing analgesia and obstetric outcome using single-injection intrathecal opioids versus epidural local anesthetics suggest that intrathecal opioids provide comparable analgesia with few serious side effects. This meta-analysis compared the analgesic efficacy, side effects, and obstetric outcome of single-injection intrathecal opioid techniques versus epidural local anesthetics in laboring women. Relevant clinical studies were identified using electronic and manual searches of the literature covering the period from 1989 to 2000. Searches used the following descriptors: intrathecal analgesia, spinal opioids, epidural analgesia, epidural local anesthetics, and analgesia for labor. Data were extracted from 7 randomized clinical trials comparing analgesic measures, incidence of motor block, pruritus, nausea, hypotension, mode of delivery, and/or Apgar scores. Combined test results indicated comparable analgesic efficacy 15 to 20 minutes after injection with single-injection intrathecal opioid administration. Intrathecal opioid injections were associated with a greater incidence of pruritus (odds ratio, 14.01; 99% confidence interval, 6.9 to 28.3), but there was no difference in the incidence of nausea or in the method of delivery. Published studies suggest that intrathecal opioids provide comparable early labor analgesia when compared with epidural local anesthetics. Intrathecal opioid administration results in a greater incidence of pruritus. The choice of technique does not appear to affect the method of delivery.

    We prospectively investigated the incidence of asthmatic attacks in 94 patients (1.5%) who were diagnosed as definite asthma. We separated the patients into three groups: epidural anesthesia (n = 10) including combined spinal/epidural anesthesia (n = 7), combined epidural and general anesthesia (n = 23), and general anesthesia (n = 54). General anesthesia was induced with propofol or midazolam and maintained with N2O and O2 with sevoflurane in adults. Patients who underwent epidural anesthesia and combined spinal and epidural anesthesia showed no asthmatic attacks. The incidence of bronchospasm with combined epidural and general anesthesia was 2/23. The incidence of bronchospasm with general anesthesia was 4/54. Bronchoconstriction occurred after tracheal intubation in 5 patients except in one patient, in whom it occurred after induction of anesthesia with midazolam. All episodes of bronchospasm in the operative period were treated successfully. The frequency of bronchospasm did not depend on the severity of asthmatic symptoms or the chronic use of bronchodilators before operation. These findings suggest that tracheal intubation, not the choice of anesthetic, plays an important role in the pathogenesis of bronchospasm.

    Around 600 spinal epidural hematoma cases have been previously reported. Incidence of paraplegia after epidural anesthesia varies between 0,0005 and 0,02%. Several possible etiologies have been described in the literature, including surgery, trauma, anticoagulant therapy, arteriovenous malformations, pregnancy and lumbar puncture. Spinal and epidural anesthesic procedures represent the tenth most common cause. But in combination with anticoagulant therapy, the forementioned procedures increase its incidence until reaching the fifth most common etiological group. We report the case of an 80 year-old-man with a cervical epidural hematoma who had a good outcome with conservative management. 80 year-old-man that developed intense cervicalgia with lower limbs weakness showing complete paraplegia and arreflexia 2 hours after analgesic treatment with epidural cervical infiltration for cervicoartrosis. Cervical MRI showed epidural cervical hematoma between C4 and T1 levels. The patient is transferred to our facilities in order to perform surgery. But after showing fast recovery, medical conservative management was elected. After one month, the patient's condition has improved showing no neurological deficits and complete resorption is seen in MRI. Nowadays, trend is to perform surgery in patients with spinal hematoma and significant neurological deterioration during the first hours. However, good neurological outcomes can be achieved with conservative management, in well selected patients with non progressive, incomplete and partial deficits. Presently, we can not predict which is the best treatment for each case.

    To determine whether epidural administration of detomidine hydrochloride to cattle induced analgesia of the perineum and to compare analgesic and systemic effects of epidural versus i.m. administration of detomidine at a dose of 40 microg/kg in cattle. 18 healthy adult cows. 6 cows were given detomidine by epidural administration, 6 were given detomidine i.m., and 6 (control group) were not given detomidine. Analgesia was assessed by determining responses to needle pinpricks in the perineum and flank and by applying electrical stimuli to the perineum and flank and determining the voltage that induced an avoidance response. Degree of sedation and ataxia were scored, and mean arterial pressure, heart rate, respiratory rate, and frequency of ruminal contractions were measured. Epidural and i.m. administration of detomidine induced comparable degrees of analgesia of the perineum and flank, accompanied by moderate sedation and ataxia, hypertension, cardiorespiratory depression, and rumen hypomotility. Epidural and i.m. administration of detomidine at a dose of 40 microg/kg induced similar analgesic and systemic effects in cattle. Epidural administration of detomidine did not appear to be advantageous over i.m. administration.

    A case report describing an unusual incident of quadriplegia in a young adult male caused by an epidural varix at the cervicothoracic junction. To report an unusual case of quadriplegia caused by an epidural varix at the cervicothoracic junction. Epidural varices are dilated tortuous elongated veins inside the central canal. In degenerative spinal stenosis, these varices are a result of venous stagnation and contribute to the pathogenesis of radicular pain. In the absence of stenosis, primary varicosities develop as a result of dynamic obstruction to venous outflow during spinal movements. A primary epidural varix can produce neurologic deficit similar to a space occupying lesion within the spinal canal. The myeloradiculopathy is of a slow progressive nature. A young man presented with an acute onset flaccid quadriplegia in the absence of significant trauma. Magnetic resonance imaging revealed an extradural space occupying lesion at the cervicothoracic junction that was diagnosed as an isolated epidural varix during surgery. No neurologic recovery occurred. Postoperative magnetic resonance imaging revealed a syrinx in the cervicothoracic cord. In the absence of other precipitating factors, the cord injury was attributed to the epidural varix. A temporary impedance to the venous outflow with the increase in the venous pressure has been hypothesized as the mechanism of cord injury.

    Full Text Available Background and Aims: The role of clonidine as an adjuvant to regional blocks to hasten the onset of the local anesthetics or prolong their duration of action is proven. The efficacy of dexamethasone compared to clonidine as an adjuvant is not known. We aimed to compare the efficacy of dexamethasone versus clonidine as an adjuvant to 1.5% lignocaine with adrenaline in infraclavicular brachial plexus block for upper limb surgeries. Material and Methods: Fifty three American Society of Anaesthesiologists-I and II patients aged 18-60 years scheduled for upper limb surgery were randomized to three groups to receive 1.5% lignocaine with 1:200,000 adrenaline and the study drugs. Group S (n = 13 received normal saline, group D (n = 20 received dexamethasone and group C (n = 20 received clonidine. The time to onset and peak effect, duration of the block (sensory and motor and postoperative analgesia requirement were recorded. Chi-square and ANOVA test were used for categorical and continuous variables respectively and Bonferroni or post-hoc test for multiple comparisons. P < 0.05 was considered significant. Results: The three groups were comparable in terms of time to onset and peak action of motor and sensory block, postoperative analgesic requirements and pain scores. 90% of the blocks were successful in group C compared to only 60% in group D (P = 0.028. The duration of sensory and motor block in group S, D and C were 217.73 ± 61.41 min, 335.83 ± 97.18 min and 304.72 ± 139.79 min and 205.91 ± 70.1 min, 289.58 ± 78.37 min and 232.5 ± 74.2 min respectively. There was significant prolongation of sensory and motor block in group D as compared to group S (P < 0.5. Time to first analgesic requirement was significantly more in groups C and D as compared with group S (P < 0.5. Clinically significant complications were absent. Conclusions: We conclude that clonidine is more efficacious than dexamethasone as an adjuvant to 1.5% lignocaine in brachial

  13. Study Protocol- Lumbar Epidural Steroid Injections for Spinal Stenosis (LESS: a double-blind randomized controlled trial of epidural steroid injections for lumbar spinal stenosis among older adults

    Full Text Available Abstract Background Lumbar spinal stenosis is one of the most common causes of low back pain among older adults and can cause significant disability. Despite its prevalence, treatment of spinal stenosis symptoms remains controversial. Epidural steroid injections are used with increasing frequency as a less invasive, potentially safer, and more cost-effective treatment than surgery. However, there is a lack of data to judge the effectiveness and safety of epidural steroid injections for spinal stenosis. We describe our prospective, double-blind, randomized controlled trial that tests the hypothesis that epidural injections with steroids plus local anesthetic are more effective than epidural injections of local anesthetic alone in improving pain and function among older adults with lumbar spinal stenosis. Methods We will recruit up to 400 patients with lumbar central canal spinal stenosis from at least 9 clinical sites over 2 years. Patients with spinal instability who require surgical fusion, a history of prior lumbar surgery, or prior epidural steroid injection within the past 6 months are excluded. Participants are randomly assigned to receive either ESI with local anesthetic or the control intervention (epidural injections with local anesthetic alone. Subjects receive up to 2 injections prior to the primary endpoint at 6 weeks, at which time they may choose to crossover to the other intervention. Participants complete validated, standardized measures of pain, functional disability, and health-related quality of life at baseline and at 3 weeks, 6 weeks, and 3, 6, and 12 months after randomization. The primary outcomes are Roland-Morris Disability Questionnaire and a numerical rating scale measure of pain intensity at 6 weeks. In order to better understand their safety, we also measure cortisol, HbA1c, fasting blood glucose, weight, and blood pressure at baseline, and at 3 and 6 weeks post-injection. We also obtain data on resource utilization

    Due to the high rates of epidural failure (3-32%), novel techniques are required to objectively assess the successfulness of an epidural block. In this study we therefore investigated whether thermographic temperature measurements have a higher predictive value for a successful epidural block when compared to the cold sensation test as gold standard. Epidural anesthesia was induced in 61 patients undergoing elective abdominal, thoracic or orthopedic surgery. A thermographic picture was recorded at 5, 10 and 15 min following epidural anesthesia induction. After 15 min a cold sensation test was performed. Epidural anesthesia is associated with a decrease in skin temperature. Thermography predicts a successful epidural block with a sensitivity of 54% and a PPV of 92% and a specificity of 67% and a NPV of 17%. The cold sensation test shows a higher sensitivity and PPV than thermography (97 and 93%), but a lower specificity and NPV than thermography (25 and 50%). Thermographic temperature measurements can be used as an additional and objective method for the assessment of the effectiveness of an epidural block next to the cold sensation test, but have a low sensitivity and negative predictive value. The local decrease in temperature as observed in our study during epidural anesthesia is mainly attributed to a core-to-peripheral redistribution of body heat and vasodilation.

    Instituting drug holidays for chronic opioid using patients is becoming commonplace for pain practitioners initiating procedures such as intrathecal pump or spinal cord stimulator trials. As such, pain practitioners need to be adept in their management of acute opioid withdrawal. Successfully weaning an opioid dependent patient off of chronic opioids requires a thorough knowledge of the available adjuvants to assist in this process. However, that selection can become exhausted by adjuvant side effects or by ineffective attenuation of opioid withdrawal symptoms. In that case, novel drugs, or novel application of currently available medications must be sought after to assist in the drug holiday. We present a case in which refractory muscle spasms secondary to opioid withdrawal were successfully treated with an over-the-counter supplement that is not typically used for the attenuation of opioid withdrawal symptoms. In a patient intolerant to the side effects of clonidine, we were able to successfully wean chronic opiates by treating refractory muscle spasms with the serotonin precursor, 5-hydroxytryptophan (5-HTP). We hypothesize that our success with this medication gives further credence to the role of serotonin in opioid withdrawal somatic symptomatology, and supports the need for future research to clarify the role of serotonin precursors or serotonin modulating drugs as potential alternatives in those unable to follow standard treatment protocols.

    The objectives of this study were to determine the analgesic and motor effects of a high-volume intercoccygeal epidural injection of bupivacaine at 2 concentrations in cows. A prospective, randomized, blinded, crossover trial was conducted on 6 adult cows. An indwelling epidural catheter was placed in the first intercoccygeal space and advanced 10 cm cranially. All the cows received 3 treatments with a washout period of 48 h: saline (control), 0.125% bupivacaine (high dose), or 0.0625% bupivacaine (low dose), at a final volume of 0.15 mL per kilogram of body weight, infused manually into the epidural space over a period of 15 min. The anal and tail tone and motor deficits of the pelvic limbs were evaluated in 5 of the cows with use of a numerical rating scale and a visual analogue scale (VAS). Sensory block was assessed in 4 of the cows by the response to needle pricks in different regions with the use of a VAS. Measurements were obtained before and at different time points after injection, up to 360 min. Analysis of variance for repeated measures and post-hoc Tukey’s and Dunnett’s tests were used. Differences were considered significant when the P-value was ≤ 0.05. One cow became recumbent 6 h after injection. Anal and tail tones were significantly decreased and motor deficits of the pelvic limbs were significantly increased after bupivacaine treatment compared with control treatment. The overall mean VASpain scores ± standard deviation were 66 ± 8 after control treatment, 52 ± 5 after low-dose bupivacaine treatment, and 43 ± 5 after high-dose bupivacaine treatment. The pain scores were significantly lower in caudal regions up to the saphenous nerve after high-dose bupivacaine treatment compared with control treatment and significantly lower in the anus, vulva, and tail after low-dose bupivacaine treatment compared with control treatment. Thus, analgesia with moderate motor deficits of the pelvic limbs may be obtained with 0.125% bupivacaine administered

    Epidural neuroplasty using a Racz catheter has a therapeutic effect. Studies have found no correlation between foraminal stenosis and the outcome of epidural neuroplasty, which is thought to depend on contrast runoff. To examine the correlation between the contrast spread pattern and pain reduction in cervical epidural neuroplasty using a Racz catheter. Retrospective study. An interventional pain-management practice in a university hospital. Fluoroscopic images were reviewed retrospectively. The spread of contrast from the neural foramen to a nerve root was called contrast runoff. If the contrast did not spread in this manner, then there was no contrast runoff. We defined successful epidural neuroplasty as a 50% or greater reduction from the pre-procedure numeric rating scale (NRS) score for total pain, and an at least 40% reduction in the neck pain and disability scale (NPDS) score. This study reviewed 169 patients. Among the patients who had a contrast runoff pattern, the epidural neuroplasty was rated as successful in 96 (74.4%), 97 (75.2%), 86 (66.7%), and 79 (61.2%) cases one, 3, 6, and 12 months after the procedure, respectively. When there was no contrast runoff, the epidural neuroplasty was successful in 12 (30%), 12 (30%), 10 (25%), and 10 (25%) cases at one, 3, 6, and 12 months after the procedure (P runoff pattern had odds ratios of 6.788, 7.073, 6.000, and 4.740 at one, 3, 6, and 12 months, respectively (P runoff pattern had a higher success rate. Contrast runoff should be observed during neuroplasty, even in the presence of foraminal stenosis.

    Full Text Available Background and Aims: Low concentration local anaesthetic improves uteroplacental blood flow in antenatal period and during labour in preeclampsia. We compared neonatal outcome after epidural ropivacaine plus fentanyl with intramuscular tramadol analgesia during labour in high-risk parturients with intrauterine growth restriction of mixed aetiology. Methods: Forty-eight parturients with sonographic evidence of foetal weight <1.5 kg were enrolled in this non-randomized, double-blinded prospective study. The epidural (E group received 0.15% ropivacaine 10 ml with 30 μg fentanyl incremental bolus followed by 7–15 ml 0.1% ropivacaine with 2 μg/ml fentanyl in continuous infusion titrated until visual analogue scale was three. Tramadol (T group received intramuscular tramadol 1 mg/kg as bolus as well as maintenance 4–6 hourly. Neonatal outcomes were measured with cord blood base deficit, pH, ionised calcium, sugar and Apgar score after delivery. Maternal satisfaction was also assessed by four point subjective score. Results: Baseline maternal demographics and neonatal birth weight were comparable. Neonatal cord blood pH, base deficit, sugar, and ionised calcium levels were significantly improved in the epidural group in comparison to the tramadol group. Maternal satisfaction (P = 0.0001 regarding labour analgesia in epidural group was expressed as excellent by 48%, good by 52% whereas it was fair in 75% and poor in 25% in the tramadol group. Better haemodynamic and pain scores were reported in the epidural group. Conclusion: Epidural labour analgesia with low concentration local anaesthetic is associated with less neonatal cord blood acidaemia, better sugar and ionised calcium levels. The analgesic efficacy and maternal satisfaction are also better with epidural labour analgesia.

    It has been suggested that the development of maternal fever during epidural analgesia could be due to intrapartum infection. We investigated whether antibiotic prophylaxis before epidural placement decreases the rate of epidural-related fever. In this double-blind, placebo-controlled trial, 400 healthy nulliparous women requesting epidural analgesia were randomly assigned to receive either cefoxitin 2 g or placebo immediately preceding initiation of epidural labor analgesia. Maternal tympanic temperature was measured hourly, and intrapartum fever was defined as a maternal temperature of ≥38°C. Neonates born to women with fever were evaluated for possible sepsis, and available placentas were evaluated for the presence of neutrophilic inflammation. The primary outcome was maternal fever during epidural analgesia. Thirty-eight percent of women in the cefoxitin group and 40% of women in the placebo group developed fever (P = 0.68). The risk difference (95% confidence interval) for fever ≥38°C during labor (antibiotic versus placebo) was -2.0% (-11.5 to 7.5), and for fever >39°C during labor was -1.5% (-4.7 to 1.7). Approximately half of each study group had placental neutrophilic inflammation, but administration of cefoxitin had no significant effect on any grade of neutrophilic inflammation. Fever developed significantly more often in the women with placental neutrophilic inflammation compared with those without such inflammation (73/158 vs 33/144, P labor epidural analgesia is associated with placental inflammation, but fever and placental inflammation were not reduced with antibiotic prophylaxis. This finding suggests that infection is unlikely to be the cause in its development.

    Palpation method is widely used in clinical practice to identify the puncture site during combined spinal-epidural (CSE) blocks. Tuffier's line, is an anatomical landmark between two iliac crests (inter-cristal), which is widely used to identify the puncture site during CSE blocks is not always an indicator for specific vertebral level or inter-vertebral space. One hundred and Ten (110) women were scheduled for normal vaginal delivery and were randomized into two equal groups; palpation group and an ultrasound guided group to detect the efficacy of puncture ultrasound before CSE blocks to increase chances of successful CSE procedure on the first attempt and to reduce the number of attempts or punctures during insertion of CSE catheter. There were no significant differences between two studied groups regarding; maternal age, weight and height, while, there was a significant difference between two studied groups regarding; parity. Percentage of successful CSE procedure on the first attempt was significantly higher (67.27%) in ultrasound compared to palpation group (40%). Number of punctures (attempts) were significantly less in ultrasound (1.2 ± 0.6) compared to palpation group (2.3 ± 0.8) and the number of redirections was also significantly less in ultrasound (1.4 ± 0.5) compared to palpation group (2.8 ± 1.6). Although, time to identify puncture site was significantly longer in ultrasound compared to palpation group and total procedure time was longer in ultrasound (9.1 ± 1.5 min) compared to palpation group (6.2 ± 1.2 min), there was no significant difference between two studied groups regarding; time to identify puncture site and total procedure time. Two cases of dural puncture in palpation versus no cases in ultrasound group and two cases of intravascular catheter placement (one in each group), with no significant difference between two groups. Pre- puncture ultrasound guided epidural insertion before vaginal delivery, increases the chance of a

    Persistent postsurgical pain (PPP) after thoracotomy effect 50% to 80%. Nerve damage and central sensitization involving NDMDAr activation may play an important role. This study evaluates the efficacy of adding intravenous (IV) or epidural ketamine to thoracic epidural analgesia (TEA) after thoracotomy. Double-blind randomized study on patients undergoing thoracotomy allocated to one of the following: group Kiv (IV racemic ketamine 0.5 mg/kg preincisional +0.25 mg/kg/h for 48 h), group Kep (epidural racemic ketamine 0.5 mg/kg preincisional +0.25 mg/kg/h for 48 h), or group S (saline). Postoperative analgesia was ensured by TEA with ropivacaine and fentanyl. Pain visual analog scales (VAS), Neuropathic Pain Symptom Inventory, Catastrophizing Scale, and Quantitative Sensory Testing, measuring both the peri-incisional and distant hyperalgesia area, were conducted preoperatively and postoperatively until 6 months. Plasma ketamine levels and stability of the analgesic solutions were analyzed. A total of 104 patients were included. PPP incidence was 20% at 6 months. Pain scores on coughing were significantly lower in Kiv and Kep than in S at 24 and 72 hours, but there were no differences afterwards. There were no significant differences in pain at rest, Neuropathic Pain Symptom Inventory, and Catastrophizing Scale, or in the area of mechanical allodynia at any time. Adverse effects were mild. Plasma ketamine levels did not differ significantly between groups. Analgesic solutions were stable. Adding epidural or IV racemic ketamine to TEA after thoracotomy did not lead to any reduction in PPP or allodynia. Epidural administration produced similar plasma ketamine levels to the IV route.

    Purpose. To assess the performance of sterile saline solution as the sole contrast agent for percutaneous magnetic resonance imaging (MRI)-guided epidural injections at 1.5 T. Methods. A retrospective analysis of two different techniques of MRI-guided epidural injections was performed with either gadolinium-enhanced saline solution or sterile saline solution for documentation of the epidural location of the needle tip. T1-weighted spoiled gradient echo (FLASH) images or T2-weighted single-shot turbo spin echo (HASTE) images visualized the test injectants. Methods were compared by technical success rate, image quality, table time, and rate of complications. Results. 105 MRI-guided epidural injections (12 of 105 with gadolinium-enhanced saline solution and 93 of 105 with sterile saline solution) were performed successfully and without complications. Visualization of sterile saline solution and gadolinium-enhanced saline solution was sufficient, good, or excellent in all 105 interventions. For either test injectant, quantitative image analysis demonstrated comparable high contrast-to-noise ratios of test injectants to adjacent body substances with reliable statistical significance levels (p < 0.001). The mean table time was 22 ± 9 min in the gadolinium-enhanced saline solution group and 22 ± 8 min in the saline solution group (p = 0.75). Conclusion. Sterile saline is suitable as the sole contrast agent for successful and safe percutaneous MRI-guided epidural drug delivery at 1.5 T.

    Epidural steroid injections (ESI) are the most common pain management procedure performed in the US, however evidence of efficacy is limited. In addition, there is early evidence that the high dose of corticosteroids used can have systemic side effects. We describe the results of a case series evaluating the use of platelet lysate (PL) epidural injections for the treatment of lumbar radicular pain as an alternative to corticosteroids. Registry data was obtained for patients (N = 470) treated with PL epidural injections presenting with symptoms of lumbar radicular pain and MRI findings that were consistent with symptoms. Collected outcomes included numeric pain score (NPS), functional rating index (FRI), and a modified single assessment numeric evaluation (SANE) rating. Patients treated with PL epidurals reported significantly lower (p < .0001) NPS and FRI change scores at all time points compared to baseline. Post-treatment FRI change score means exceeded the minimal clinically important difference beyond 1 month. Average modified SANE ratings showed 49.7% improvement at 24 months post-treatment. Twenty-nine (6.3%) patients reported mild adverse events related to treatment. Patients treated with PL epidurals reported significant improvements in pain, exceeded the minimal clinically important difference (MCID) for FRI, and reported subjective improvement through 2-year follow-up. PL may be a promising substitute for corticosteroid.

    In this study, comparative antinociceptive and sedative effects of epidural administration of romifidine and detomidine in buffalo were evaluated. Eighteen healthy adult buffalo, allocated randomly in three groups (two experimental and one control; n=6) received either 50 μg/kg of romifidine or detomidine diluted in sterile saline (0.9 per cent) to a final volume of 20 ml, or an equivalent volume of sterile saline epidurally. Antinociception, sedation and ataxia parameters were recorded immediately after drug administration. Epidural romifidine and detomidine produced mild to deep sedation and complete antinociception of the perineum, inguinal area and flank, and extended distally to the coronary band of the hindlimbs and cranially to the chest area. Times to onset of antinociception and sedation were significantly shorter with romifidine than with detomidine. The antinociceptive and sedative effects were significantly longer with romifidine than with detomidine. Romifidine or detomidine could be used to provide a reliable, long-lasting and cost-effective method for achieving epidural anaesthesia for standing surgical procedures in buffalo. Romifidine induces a longer antinociceptive effect and a more rapid onset than detomidine. Consequently, epidural romifidine may offer better therapeutic benefits in the management of acute postoperative pain. British Veterinary Association.

    Remifentanil with appropriate pharmacological properties seems to be an ideal alternative to epidural analgesia during labour. A retrospective cohort study was undertaken to assess the efficacy and safety of remifentanil intravenous patient-controlled analgesia (IVPCA) compared with epidural analgesia. Medical records of 370 primiparas who received remifentanil IVPCA or epidural analgesia were reviewed. Pain and sedation scores, overall satisfaction, the extent of pain control, maternal side effects and neonatal outcome as primary observational indicators were collected. There was a significant decline of pain scores in both groups. Pain reduction was greater in the epidural group throughout the whole study period (0∼180 min) (Panalgesia. And logistic regression analysis demonstrated that nausea, vomiting were associated with oxytocin usage and instrumental delivery, and dizziness was associated to the type and duration of analgesia. Neonatal outcomes such as Apgar scores and umbilical-cord blood gas analysis were within the normal range, but umbilical pH and base excess of neonatus in the remifentanil group were significantly lower. Remifentanil IVPCA provides poorer efficacy on labor analgesia than epidural analgesia, with more sedation on parturients and a trend of newborn acidosis. Despite these adverse effects, remifentanil IVPCA can still be an alternative option for labor analgesia under the condition of one-to-one bedside care, continuous monitoring, oxygen supply and preparation for neonatal resuscitation.

    Full Text Available Following the introduction of epidural for labor analgesia, debate has centered on the issue of its effect on outcome of labor; in terms of length of labor and increase in the rate of instrumental vaginal delivery and cesarean section (CS. There is no ideal study on the effect of epidural analgesia (EA on the outcome of labor due to logistic problems in randomization, blinding and getting a control group; as a result these queries are partly answered. Despite these problems, it has been established that labor epidural has minimal effect on progress of established labor and maternal request should be a sufficient indication to start an epidural. Although instrumental vaginal delivery is probably increased with epidural but obstetrician practice, pain free patient and teaching opportunity are likely factors increasing the incidence. Maternal-fetal factors and obstetric management and not the use of EA are the most important determinants of the CS rate. The purpose of this review is to summarize data from controlled trials addressing the question of whether neuraxial labor analgesia causes an increased risk of CS or rate of instrumental delivery. In addition, the review discusses whether the timing of initiation of analgesia infl uences the mode of delivery.

    This study evaluates the ability of four commonly used analgesics (ketamine HCl, gabapentin, clonidine HCl, and baclofen), when incorporated into two transdermal compounding bases, Lipoderm and Lipoderm ActiveMax, to penetrate human cadaver trunk skin in vitro, using the Franz finite dose model. In vitro experimental study. Methods. Ketamine HCl 5% w/w, gabapentin 10% w/w, clonidine HCl 0.2% w/w, and baclofen 2% w/w were compounded into two transdermal bases, Lipoderm and Lipoderm ActiveMax. Each compounded drug formulation was tested on skin from three different donors and three replicate skin sections per donor. The Franz finite dose model was used in this study to evaluate the percutaneous absorption and distribution of drugs within each formulation. Rapid penetration to peak flux was detected for gabapentin and baclofen at approximately 1 hour after application. Clonidine HCl also had a rapid penetration to peak flux occurring approximately 1 hour after application and had a secondary peak at approximately 40 hours. Ketamine HCl exhibited higher overall absorption rates than the other drugs, and peaked at 6–10 hours. Similar patterns of drug distribution within the skin were also observed using both transdermal bases. This study suggests that the combination of these 4 analgesic drugs can be successfully delivered transdermally, using either Lipoderm or Lipoderm ActiveMax. Compounded transdermal drug preparations may then provide physicians with an alternative to traditional oral pain management regimens that can be personalized to the specific patient with the potential for enhanced pain control.

    Sedation is an essential part of paediatric critical care. Midazolam, often in combination with opioids, is the current gold standard drug. However, as it is a far-from-ideal agent, clonidine is increasingly being used in children. This drug is prescribed off-label for this indication, as many drugs in paediatrics are. Therefore, the CLOSED trial aims to provide data on the pharmacokinetics, safety and efficacy of clonidine for the sedation of mechanically ventilated patients in order to obtain a paediatric-use marketing authorisation. The CLOSED study is a multicentre, double-blind, randomised, active-controlled non-inferiority trial with a 1:1 randomisation between clonidine and midazolam. Both treatment groups are stratified according to age in three groups with the same size: <28 days (n=100), 28 days to <2 years (n=100) and 2-18 years (n=100). The primary end point is defined as the occurrence of sedation failure within the study period. Secondary end points include a pharmacokinetic/pharmacodynamic relationship, pharmacogenetics, occurrence of delirium and withdrawal syndrome, opioid consumption and neurodevelopment in the neonatal age group. Logistic regression will be used for the primary end point, appropriate statistics will be used for the secondary end points. Written informed consent will be obtained from the parents/caregivers. Verbal or deferred consent will be used in the sites where national legislation allows. The study has institutional review board approval at recruiting sites. The results will be published in a peer-reviewed journal and shared with the worldwide medical community.

    Posterior fossa dural venous sinus thrombus is a well-described complication of head trauma, especially when fracture crosses the dural sinus grooves or in association with epidural hemorrhage. We have found that post-traumatic posterior fossa epidural hematoma compressing a dural venous sinus can mimic dural venous thrombus. To discuss the CT and MRI findings of posterior fossa epidural hemorrhages simulating sinus thrombosis, to make radiologists aware of this important imaging pitfall. We describe radiologic findings in four children in whom a posterior fossa epidural hemorrhage mimicked dural venous sinus thrombus. Routine CT head and CT venography were obtained on Toshiba volume and helical CT scanners. MRI and MR venography were performed on a Philips scanner. In all cases there was medial displacement and compression of the posterior fossa dural venous sinuses without intraluminal thrombosis. The epidural hemorrhage was seen tracking along sinus grooves in the occipital bone, peeling the dura containing the sinuses from the calvarium and compressing the sinus, simulating thrombosis on axial CT views. Both venous sinus thrombosis and posterior fossa epidural hemorrhages in children are well-described complications of head trauma. Posterior fossa epidural hemorrhage can mimic a sinus thrombus by compressing and displacing the sinuses. It is important to recognize this pitfall because treatment of a suspected thrombus with anticoagulation can worsen epidural hemorrhage. (orig.)

    Purpose: When patients show progression after conventional fractionated radiation for spine metastasis, further radiation and surgery may not be options. Stereotactic body radiotherapy (SBRT) has been successfully used in treatment of the spine and may be applicable in these cases. We report the use of SBRT for 60 consecutive patients (81 lesions) who had radiological progressive spine metastasis with epidural involvement after previous radiation for spine metastasis. Methods and Materials: SBRT was used with fiducial and vertebral anatomy-based targeting. The radiation dose was prescribed based on the extent of spinal canal involvement; the dose was 8 Gy × 3 = 24 Gy when the tumor did not touch the spinal cord and 5 to 6 Gy x 5 = 25 to 30 Gy when the tumor abutted the cord. The cord surface received up to the prescription dose with no hot spots in the cord. Results: The median overall survival was 11 months, and the median progression-free survival was 9 months. Overall, 93% of patients had stable or improved disease while 7% of patients showed disease progression; 65% of patients had pain relief. There was no significant toxicity other than fatigue. Conclusions: SBRT is feasible and appears to be an effective treatment modality for reirradiation after conventional palliative radiation fails for spine metastasis patients.
