    Full Text Available El correcto tratamiento del dolor postoperatorio constituye una prioridad dentro de los objetivos del anestesiólogo. En pacientes con patología vascular severa quirúrgica, el tratamiento analgésico efectivo se suele realizar mediante bloqueo continuo epidural. Sin embargo, la administración de analgésicos, tanto opiáceos como no opiáceos, por vía intravenosa, es una alternativa a la vía epidural cuando esta es desestimada. Caso clínico: Presentamos el caso de un paciente varón de 63 años portador de un bypass fémoro-poplíteo a primera porción en miembro inferior izquierdo, el cual es intervenido quirúrgicamente y con carácter urgente tras el diagnóstico de falso aneurisma séptico de arteria iliaca izquierda con rotura de anastomosis fémoro-poplítea. Se optó por una anestesia general basada en la analgesia con remifentanilo frente a bloqueo central epidural dado el carácter urgente de la cirugía y la ingesta habitual de antiagregantes plaquetarios. Se planificó como estrategia analgésica postoperatoria la administración de remifentanilo a dosis sedoanalgésicas (Introduction: The appropriate management of postoperative pain is a priority among the objectives of the anesthesiologist. In patients with severe surgical vascular pathology, an effective analgesic treatment is usually provided with epidural continuous blockade. However, the intravenous administration of analgesics, either opiates or non opiates, is an alternative to the epidural route when this has to be dismissed. Clinical case: We present the case of a 63-years old male patient carrying a femoro-popliteus bypass in the first portion of the left lower limb that underwent emergency surgery after being diagnosed of a false septic aneurysm in the left iliac artery with breakage of the femoro-popliteus anastomosis. General anesthesia based on remifentanyl was decided instead of epidural central blockade due to the urgent nature of the surgery and the regular

    Hypothermia and shivering are common during epidural anesthesia for cesarean delivery but are not always accompanied by a sensation of coldness. To test the hypothesis that central temperature changes are not perceived during epidural anesthesia, we measured central and skin temperatures and thermal perception in 30 patients undergoing cesarean delivery with epidural anesthesia. Central temperature decreased 1.0 +/- 0.6 degrees C from control values during anesthesia and surgery, but thermal perception scores did not reflect central temperatures (P = 0.56) or changes in central temperature (P = 0.63). A feeling of warmth was significantly correlated with increased mean skin temperature (P = 0.02) and increased upper body skin temperature (P = 0.03). We conclude that central temperature is poorly perceived and is less important than skin temperature in determining thermal perception during high levels of epidural anesthesia.

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. These conclusions support the effectiveness of epidural analgesia and its favorable benefit/risk relation to the control of labor pain.

    Full Text Available Introducción: La ketamina de uso corriente es una droga utilizada principalmente para la inducción y el mantenimiento de la anestesia, compuesta por una mezcla racémica de enantiómeros R (- y S (+. En la década de los años 80 comienza la administración humana de la ketamina por vía epidural. A partir de entonces se han presentado disímiles investigaciones para justificar su acción analgésica en este espacio con varias hipótesis: 1 supresión específica laminar de las astas dorsales, 2 mediación por el sistema opioide endógeno y sustancia gris periacueductal, y 3 bloqueo de los canales del calcio por antagonismo no competitivo de los receptores N-metil-d-aspartato. Objetivo: Demostrar la eficacia de la ketamina por vía epidural como analgésico postoperatorio en la cirugía de hemiabdomen inferior. Material y Método: Se realizó un ensayo clínico aleatorizado y prospectivo en una muestra de 50 pacientes operados de hernia inguinal electiva. Los pacientes fueron divididos en dos grupos, un grupo tratado con 50 mg de ketamina y otro grupo al que se le administró una dosis de 2 mg de morfina liofilizada. Resultados: la ketamina por vía epidural en una dosis de 50 mg proporciona una analgesia adecuada por un período de al menos de 6 horas. La morfina brinda una analgesia por encima de las 18 horas. Conclusión: La ketamina por vía epidural es menos efectiva que la morfina desde el punto de vista analgésico, pero es una alternativa importante pues permite disminuir la dosis de morfina si se combinan ambos fármacos o se asocia a anestésicos locales.Introduction: Ketamine is a drug used for induction and maintenance of anesthesia, exists as a racemic mixture of R- and S+-enantiomers.

Realizou-se um ensaio clínico duplo-cego, prospectivo e aleatório, incluindo sessenta mulheres nulíparas da Maternidade do CAISM/UNICAMP. No momento da analgesia, as mulheres foram aleatoriamente alocadas em dois grupos: BS, recebendo 12,5 mg de bupivacaína com adrenalina mais 30 µg de sufentanil e BP, recebendo 12,5 mg de bupivacaína com adrenalina mais placebo. Foram avaliados os parâmetros relativos à qualidade e duração da analgesia, duração do trabalho de parto e também possíveis efeitos sobre o recém-nascido. Os resultados mostraram a superioridade da adição do sufentanil sobre o grau de analgesia durante o tempo de ação da primeira dose de anestésico local. Não houve aumento na duração do trabalho de parto depois do início da analgesia quando se compararam ambos os grupos, nem qualquer diferença quanto à via de parto. Não houve também diferenças entre os grupos com relação à avaliação dos recém-nascidos. Conclui-se que a associação de 30 µg de sufentanil à primeira dose de bupivacaína é segura e eficaz, melhorando a qualidade da analgesia, sua duração e não afetando a progressão do trabalho de parto e o resultado neonatal.The purpose of the present study was to evaluate the efficacy and safety of the association bupivacaine with sufentanil for labor and delivery analgesia through a continuous epidural blockade, for both mother and the neonate.

    The purpose of this study was to investigate the characteristics of childhood acute epidural hematoma and to report our experience in recent years. A series of 35 patients below the age of 15 years treated for acute epidural hematoma at our institution between June 1991 and December 2000 was analyzed in detail. Pediatric epidural hematoma presents both age-related and atypical features when compared with epidural hematoma in adults. In selected cases, prompt surgical evacuation of the hematoma results in an excellent outcome. Outcomes seem to be directly related to the patient's preoperative neurologic status and the presence of associated intracranial lesions.

    Full Text Available Background: Acute bilateral extradural hematoma is a rare presentation of head trauma injury. In sporadic cases, they represent 0.5-10% of all extradural hematomas. However, higher mortality rates have been reported in previous series. Case Description: The authors described the case of a 28-year-old male presenting head injury, comatose, Glasgow Coma Scale of 6, anisocoric pupils without puppilary light reflex. Computed tomography showed asymmetric bilateral epidural hematomas, effacement of the lateral ventricles and sulci, midline shift and a bilateral skull fracture reaching the vertex. Surgical evacuation was performed with simultaneous hematoma drainage. Patient was discharged on the 29 th postoperative day with no neurological deficit. Conclusion: The correct approach on bilateral epidural hematomas depends on the volume, moment of diagnosis, and neurological deficit level. Simultaneous drainage of bilateral hematomas has been demonstrated to be an effective technique for it, which soon decreases the intracranial pressure and promotes an efficient resolution to the neurological damage.

    A spinal epidural abscess developed in a renal transplant recipient; results of a serum radioimmunoassay for Aspergillus antigen were positive. Laminectomy disclosed an abscess of the L4-5 interspace and L-5 vertebral body that contained hyphal forms and from which Aspergillus species was cultured. Serum Aspergillus antigen radioimmunoassay may be a valuable, specific early diagnostic test when systemic aspergillosis is a consideration in an immunosuppressed host.

    Spinal epidural hematoma and spinal epidural abscess are rare surgical emergencies resulting in significant neurologic deficits. Making the diagnosis for spinal epidural hematoma and spinal epidural abscess can be challenging; however, a delay in recognition and treatment can be devastating. The objective of this retrospective analysis study was to identify risk factors for an adverse outcome for the provider. The LexisNexis Academic legal search database was used to identify a total of 19 cases of spinal epidural hematoma and spinal epidural abscess filed against medical providers. Outcome data on trial verdicts, age, sex, initial site of injury, time to consultation, time to appropriate imaging studies, time to surgery, and whether a rectal examination was performed or not were recorded. The results demonstrated a significant association between time to surgery more than 48 hours and an unfavorable verdict for the provider. The degree of permanent neurologic impairment did not appear to affect the verdicts. Fifty-eight percent of the cases did not present with an initial deficit, including loss of bowel or bladder control. All medical professionals must maintain a high level of suspicion and act quickly. Physicians who are able to identify early clinical features, appropriately image, and treat within a 48 hour time frame have demonstrated a more favorable medicolegal outcome compared with their counterparts in filed lawsuits for spinal epidural hematoma and spinal epidural abscess cases.

    Thoracic epidural anaesthesia alone is an applied technique of anaesthesia for nephrectomy which has both advantages and limitations. Dexmedetomidine is a highly selective alpha2-adrenoreceptor agonist which has both central and peripheral analgesic properties. Forty patients undergoing nephrectomy were enrolled in this clinical trial and allocated randomly to two groups, a control group (C group) and a dexmedetomidine group (D group). The C group received epidural 0.75% levobupivacaine 12 ml with 1 ml of isotonic sodium chloride solution, while the D group received epidural 0.75% levobupivacaine 12 ml with 1 ml (0.5 µg/kg) of dexmedetomidine. Haemodynamic changes, onset time and duration of sensory and motor block, muscle relaxation score, verbal rating score for pain, sedation score and the total postoperative analgesic consumption were evaluated. Sensory blockade duration was longer in the D group than in the C group (P=0.01). The incidence of motor block and the muscle relaxation score were significantly higher in the D group compared with the C group (P=0.01). Compared with the C group, pain scores were significantly lower in the first four postoperative hours in the D group (two hours rest P=0.038; two hours activity P=0.009; four hours rest P=0.044; four hours activity P=0.003). The total amount of flurbiprofen analgesic was significantly lower in the D group compared with the C group (P=0.03). Epidural dexmedetomidine 0.5 µg/kg appears to intensify thoracic epidural anaesthesia with levobupivacaine.

    Full Text Available Introducción: El hematoma epidural secundario a una anestesia neuroaxial es una complicación poco frecuente, pero de gran trascendencia tanto por sus implicaciones clínicas como por las médico legales; según algunos autores su incidencia puede oscilar entre 1/190.000-1/200.000 para las punciones peridurales y 1/320.000 en el caso de las espinales. El aspecto prioritario en su manejo terapéutico es el del diagnóstico y tratamiento precoz, antes de las 6-12 primeras horas. No obstante, en determinados pacientes como en el caso que presentamos puede no ser precisa la cirugía, resolviéndose el cuadro con tratamiento conservador. Caso clínico: Varón de 73 años, ASA IV, con antecedentes de cirrosis con hipertensión portal, hiperesplenismo, EPOC, obesidad, cardiopatía hipertensiva e insuficiencia tricuspídea. Se programa para alcoholización prostática al haber sido desechada la cirugía. En la analítica preoperatoria destacaba una actividad de protrombina del 80% y 90.000 plaquetas. Se realizaron varios intentos fallidos de punción espinal, finalmente fue precisa una anestesia general con ventilación espontánea mediante mascarilla laríngea, propofol, fentanilo y sevoflurano. A las 36 horas, comienza la clínica en forma de dolor intenso lumbar, sin irradiación y arreflexia cutáneo plantar, confirmándose en la RMN la presencia de un hematoma epidural de L1 a L4. Ante la ausencia de paraparesia flácida, afectación esfinteriana u otros signos sensitivo-motores y tras consulta con la Unidad de Raquis y con el Servicio de Neurología se decide tratamiento conservador y actitud expectante en forma de analgesia y monitorización neurológica estricta, clínica y radiológica. Evolucionando favorablemente en los siguientes días. Discusión: Determinadas condiciones clínicas pueden influir en la aparición de un hematoma tras la realización de un bloqueo regional central: heparinas de bajo peso molecular, punciones dificultosas

    Epidural emphysema is an exceptional complication of bronchial asthma, revealed by an incidental finding in chest tomography. We report a case of a 21-year-old man admitted with asthma attack complicated by subcutaneous and mediastinal emphysema. Chest tomography confirmed the mediastinal emphysema and also revealed the epidural emphysema within the vertebral canal. Neurological examination was negative. The patient showed complete recovery 10days after the onset of symptoms. The epidural emphysema is a rare complication during asthma attacks. The benignity of this complication should not require a systematic chest tomography.

    The incidence of epidural abscess following epidural catheterisation appears to be increasing, being recently reported as one in 1000 among surgical patients. This study was designed to investigate the antibacterial activity of various local anaesthetics and additives, used in epidural infusions, against a range of micro-organisms associated with epidural abscess. The aim was to determine which, if any, epidural infusion solution has the greatest antibacterial activity. Bupivacaine, ropivacaine and levobupivacaine crystals were dissolved and added to Mueller-Hinton Agar in concentrations of 0.06%, 0.125%, 0.2%, 0.25%, 0.5% and 1%. Fentanyl, adrenaline and clonidine were also mixed with agar in isolation and in combination with the local anaesthetics. Using a reference agar dilution method, the minimum inhibitory concentrations were determined for a range of bacteria. Bupivacaine showed antibacterial activity against Staphylococcus aureus, Enterococcus faecalis and Escherichia coli with minimum inhibitory concentrations between 0.125% and 0.25%. It did not inhibit the growth of Pseudomonas aeruginosa at any of the concentrations tested. Levobupivacaine and ropivacaine showed no activity against Staphylococcus aureus, Enterococcus faecalis and Pseudomonas aeruginosa, even at the highest concentrations tested, and minimal activity against Escherichia coli (minimum inhibitory concentrations 0.5% and 1% respectively). The presence of fentanyl, adrenaline and clonidine had no additional effect on the antibacterial activity of any of the local anaesthetic agents. The low concentrations of local anaesthetic usually used in epidural infusions have minimal antibacterial activity. While the clinical implications of this in vitro study are not known, consideration should be given to increasing the concentration of bupivacaine in an epidural infusion or to administering a daily bolus of 0.25% bupivacaine to reduce the risk of epidural bacterial growth.

    Full Text Available Epidural infusion of local analgesic and opioid are commonly used for postoperative pain relief. This combina-tion gives excellent anlgesia but nausea and vomiting remains a major concern. Low dose epidural naloxone prevents PONV induced by spinal opioids like morphine, fentanyl and sufentanil. However, it is not known that epidural naloxone administration prevents PONV induced by epidural buprenorphine. We have reported three cases of major abdominal operation in which lowdose epidural infusion of naloxone releived the symptom of buprenorphine induced severe PONV and improved the quality of analgesia.

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.

    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 Preemptive analgesia is initiating an analgesic regimen before the onset of the noxious stimulus. Damages to the tissue caused by surgical trauma generate noxious response conveyed to the central nervous system (CNS by two pathways, neural pathway and circulatory pathway. This study is a double- blinded clinical trial that included 48 patients undergoing lower extremity orthopedic surgery. The subjects were divided into two groups: group I (n=24 received 10 mL bupivacaine 0.25% from epidural route, and group II (n=24 received 10 mL NaCl 0.9% from epidural route as the control group before induction of anesthesia. Both groups were anesthetized under general anesthesia. Group I received 5 mL bupivacaine 0,5% every 90 minutes and group II received 5 mL NaCl 0,9 with similar time intraoperatively. Post-operatively, both groups received continuous bupivacaine 0,25% 4 mL/ hour until 24 hours after surgery. Measurements of cytokine levels: tumor necrosis factor-α (TNF-α, interleukin- 1β (IL-1β, IL-6 and IL-10 were done before induction of anesthesia, in the early post-operative period, at 4, 8, and 24 hours after surgery. Group I showed lower level proinflammatory cytokines level compared with group II but the difference was not statistically significant (p>0.05. The level of anti-inflammatory cytokine was higher in group I, but the difference was not statistically significant (p>0.05. Pain intensity at 4 hours, 8 hours, 24 jam hours post operative was lower significantly (p0.05 excepst at early postoperative period (p<0.05. Generally, preemptive epidural analgesia was able to suppress the cytokine responses, but not completely. In conclusion, preemptive epidural analgesia is associated with better analgesia and better hemodynamic stability compared without preemptive epidural, but unable to suppress the production of proinflammatory and anti-inflammatory cytokines.

    Epidural steroid injections are a common procedure performed by pain physicians. The American Society of Regional Anesthesia along with several other groups recently provided guidelines for performing epidural injections in the setting of anticoagulants. We present a case of a patient who developed an epidural hematoma and subsequent paraplegia despite strict adherence to these guidelines. Although new guidelines serve to direct practice, risks of devastating neurologic complications remain as evidenced by our case.

CONCLUSIONES: La técnica combinada (raqui-peridural para analgesia de parto está próxima de lo ideal. Cuidados con la técnica de anti-sepsia son necesarios para realización de bloqueos espinales. La complicación presentada ocurrió sin la aparente falla en la realización de la técnica, siendo una cuestión que es inherente al riesgo - beneficio que la técnica proporciona.BACKGRAUND AND OBJECTIVES: Meningitis is a serious complication, although rare in regional anesthesia. This report aimed at presenting a case which evolved to meningitis after combined labor spinal-epidural analgesia. CASE REPORT: Laboring patient, 25 years old, second gestation and previous c-section. Combined labor spinal-epidural analgesia was induced with double-puncture. Twenty-four hours later she presented with headache at rest, fever and mild chills, which regressed with symptomatic medication. Headache worsened in the 5th day. There were vomiting and neck pain in the 10th day. Symptoms became more severe in the 13th day. Lumbar puncture was performed. Clinical history and CSF analysis were compatible with bacterial meningitis. CONCLUSIONS: Combined labor spinal-epidural analgesia is very close to being the ideal technique. Care must be taken with the sterile technique to induce spinal blockade. The reported complication has occurred without an apparent technique failure and is inherent to technique’s risk-benefit ratio.

    Full Text Available The bacteriological profile of epidural catheters was studied in 88 patients. Skin swabs before catheterizationand before removal of catheter with their controls were cultured in TSB Medium. The catheter hub, theportion at the skin puncture site and at the tip were cultured in TSB Medium. The 1cm of the catheter bitjust before the tip was cultured in TGB medium for anaerobes.Both, the skin controls swabs and theanaerobic culture, were negative. From the remaining, 56 positive cultures were obtained. Staphylococcusepidermidis was the predominant organism in 52% followed by staphylococcus aureus 25%. The remaining23% was shared by Acinetobacter, Pseudomonas, Klebsiella, and E. coli. All the positive cultures fromskin prior to epidural catheterization had turned sterile by 48 hours, indicating continued bactericidal actionof the disinfectant. The likely source of positive skin cultures at 48 hours is hair follicles.The catheter tipculture was positive in 9 specimen, none of which resulted in the formation of epidural abscess. In 3 casesthe cultures of skin puncture site and the tip were identical indicating tracking-in of the organisms.

    Lumbar epidural varices are rare and usually mimick lumbar disc herniations. Back pain and radiculopathy are the main symptoms of lumbar epidural varices. Perineural cysts are radiologically different lesions and should not be confused with epidural varix. A 36-year-old male patient presented to us with right leg pain. The magnetic resonance imaging revealed a cystic lesion at S1 level that was compressing the right root, and was interpreted as a perineural cyst. The patient underwent surgery via right L5 and S1 hemilaminectomy, and the lesion was coagulated and removed. The histopathological diagnosis was epidural varix. The patient was clinically improved and the follow-up magnetic resonance imaging showed the absence of the lesion. Lumbar epidural varix should be kept in mind in the differential diagnosis of the cystic lesions which compress the spinal roots. PMID:23741553

    To bring attention to the MR imaging appearance of epidural hematoma (EDH) in the lumbar spine as a small mass often associated with disk herniation or an acute event. This paper will show our experience with this entity and describe criteria for its MR imaging appearance. Design and patients. Thirteen cases of prospectively diagnosed EDH of the lumbar spine were compared with 12 cases of prospectively diagnosed prominent epidural extrusion. Our criteria were retrospectively evaluated by the two authors for their presence or absence in each case. The chi-square test for nominal data was applied. MR imaging criteria utilized to distinguish EDH from disk herniation at our institution include: (1) signal different from disk, (2) high signal on T1-weighted images, either centrally or peripherally, (3) teardrop- or egg-shaped mass, in the sagittal plane, (4) size greater than half the vertebral body height in a craniocaudal dimension, (5) primarily retrosomatic epidural location, (6) plasticity - the mass is seen to conform closely to the contours of bone (e.g., in the lateral recess), (7) little or no disk space narrowing unless associated with disc herniation. Chi-square analysis demonstrated each criterion to significantly differentiate between EDH and extrusion. Only six of 13 EDH cases went to surgery in spite of their relatively large size. Two of six patients were diagnosed as having epidural clot consistent with hematoma at the time of surgery. The four patients who were not diagnosed at surgery revealed only small disk herniations or fragments of disk. The occurrence of EDH is more frequent than previously suspected. Spontaneous EDH is frequently associated with disk herniation and acute events such as sneezing or coughing. Most cases of spontaneous EDH will resolve prior to surgery with only the minority becoming chronic in order to be seen at surgery as an encapsulated mass. MR imaging can reliably identify EDH and distinguish between EDH and large disk

    Since there have been side effects reported with the administration of corticosteroids epidurally, their application has been limited. Because some nonsteroidal antiinflammatory drugs have central and spinal antinociceptive actions, we have compared the effects of indomethacin (INM) given by the epidural route to methylprednisolone (MTP). This was a prospective, comparative study in an ambulatory pain care center. Two hundred six patients with recurrent low back pain (Visual Analog Scale >7) and radiculopathy after they had had 2 or more lumbar laminectomies with the diagnosis of "postlaminectomy syndrome" were randomly assigned to 1 of 3 groups. Group I (64 patients) was given 2 epidural injections of lyophilized INM 1 mg. Group II (60 patients) received 2 injections of 2 mg of INM at the same intervals. Group III (82 patients) was treated by 2 epidural injections of MTP 80 mg. In every case, the medication was diluted in 3 mL of 0.5% bupivacaine. Reductions of pain were assessed by changes in the Visual Analog Scale; physical activities, attitude, and medication intake were graded by the Pain Progress Score recorded before each treatment and 2 wk after the last. After each injection, all patients had pain relief to Visual Analog Scale <3. Increased analgesia (P < 0.05) was noted when a double dose of INM was used (Group II) or when 80 mg of MTP was given. The total average scores of the Pain Progress Score showed significant differences at the second injection in Groups II and III only. Physical activity, emotional attitudes, and medication intake were also improved but the changes were not statistically significant. In conclusion, in this group of patients, INM produced adequate analgesia in Groups I and II, with evidence suggesting that 2 mg of INM may produce a similar degree of pain relief as 80 mg of MTP after the second injection. Other nonsteroidal antiinflammatory drugs may be explored in the future for the same purpose.

It is considered a safe and effective method for pain relief. This study aimed at comparing two bupivacaine concentrations (0.25% and 0.125% associated to fentanyl in epidural labor analgesia to determine its efficacy on pain relief and its effect on motor block. We have also observed the influence of these two concentrations on labor duration, fetal outcome and maternal satisfaction. METHODS: Participated in this prospective and double blind study 51 primiparous women who were randomized to receive one out of two bupivacaine concentrations for epidural labor analgesia (0.25% [n = 23] or 0.125% [n = 28]. Analgesia was measured using a numeric pain scale, and motor block was verified using Bromage scale. Means were compared using Student's t test, while proportions were compared using Qui-square test, with p < 0.05. RESULTS: There has been no statistical difference in pain, degree of motor block and fetal outcome between groups. Cesarean delivery rate was statistically higher in the group receiving 0.25% bupivacaine (p < 0.05. Lower concentration group patients were more satisfied with the procedure (p < 0.01. CONCLUSIONS: The association of fentanyl and 0.125% bupivacaine proved to be more beneficial as compared to 0.25% concentration. With this dose, there has been a lower incidence of adverse effects without compromising analgesia, and yet a higher rate of maternal satisfaction.

  5. 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

    Spinal epidural abscess is a rare but potentially fatal disease. A 67-year-old female suffered fever and painful swelling of the right knee and lower leg for one week. Both synovial fluid and blood cultures yielded methicillin-sensitive Staphylococcus aureus. Low back pain developed and fever was sustained despite the administration of intravenous oxacillin. Magnetic resonance imaging (MRI) of the thoracolumbar spine revealed spinal epidural abscess from T12 to S1. Because of severe hypoalbuminemia and general anasarca and followed by exploratory laparotomy for massive duodenal bleeding, she did not receive surgical intervention for the spinal epidural abscess. After intravenous administration of oxacillin 2 g 4-hourly for 12 weeks, she recovered and follow-up MRI confirmed the efficacy of the medical treatment. She remained well at 1-year follow-up. In a patient with minimal neurological deficit or surgical contraindication, spinal epidural abscess can be successfully treated with a medical regimen.

    Although epidural analgesia is routinely used in many institutions for patients undergoing hepatic resection, there are unresolved issues regarding its safety and efficacy in this setting. We performed a review of papers published in the area of anaesthesia and analgesia for liver resection surgery and selected four areas of current controversy for the focus of this review: the safety of epidural catheters with respect to postoperative coagulopathy, a common feature of this type of surgery; analgesic efficacy; associated peri-operative fluid administration; and the role of epidural analgesia in enhanced recovery protocols. In all four areas, issues are raised that question whether epidural anaesthesia is always the best choice for these patients. Unfortunately, the evidence available is insufficient to provide definitive answers, and it is clear that there are a number of areas of controversy that would benefit from high-quality clinical trials.

    Epidural anaesthesia is a widely used and accepted technique for perioperative analgesia in different kinds of surgery. Apart from analgetic effect and due to wide positve effects on patients outcome epidural analgesia is often used with general anaesthesia. It represents a reliable and reversible neural deafferentation technique that effectively contributes to a reduction of the surgical stress response with subsequent positive effects on cardiopulmonary, gastrointestinal, and immune function. Animal studies suggest that the use of epidural anaesthesia may be beneficial for cancer surgery because of less tumour recurrence. Further, a benefit is expected in patient's mortality. This article summarizes and critically discusses the current knowledge on the effects of epidural anaesthesia on pain management, cardiopulmonary as well as gastrointestinal functions and patient's outcome.

    In 1901, the first Epidural anesthesia via a caudal approach was independently described by two FrenchmanJean-Anthanase Sicard and Fernand Cathelin.. The Spanish military surgeon, Fidel Pagés Miravé, completed the lumbar approach successfully in 1921. The two possibilities for identification of the epidural space the "loss of resistance" technique and the technique of the "hanging drop" were developed by Achille Mario Dogliotti, an Italian, and Alberto Gutierrez, an Argentinean physician, at the same time. In 1956 John J. Bonica published the paramedian approach to the epidural space. As early as 1931 Eugene Aburel, a Romanian obstetrician, injected local anaesthetics via a silk catheter to perform lumbar obstetric Epidural analgesia. In 1949 the first successful continuous lumbar Epidural anaesthesia was reported by Manuel Martinez Curbelo, a Cuban. Epidural anaesthesia can be performed in sitting or lateral position in all segments of the spinal column via the median or paramedian approach. Different off-axis angles pose the challenge in learning the technique.

    Involvement of the skeletal system is a common complication of brucellosis. However, muscle involvement or paraspinal abscess formation are rare complications. Paraspinal abscess usually develops secondary to spondylitis. A case is reported here of a 33-year-old woman with symptoms of night sweats, fever and low back pain. Rose-Bengal test for brucellosis was positive and Brucella standard tube agglutination test was positive at a titre of 1/160. The diagnosis was made on MRI. The patient was treated with doxycycline and rifampin daily for 16 weeks. On day 14 of treatment, decline was observed in the patient's symptoms. In the presence of inflammatory lower back pain and fever, brucellosis should be considered particularly in the endemic areas. Furthermore, tuberculosis should be remembered in the differential diagnosis when a spinal epidural abscess is determined.

    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

    One of the potential areas for energy saving in Central Electric Power Plants are the auxiliaries system, so as to based in a preliminary energy diagnosis and considering that energy saving measures would be taken, going from the instrumentation, operational changes in equipment, as well as in using velocity variators in motors, it turns out to be that the energy consumption of auxiliaries at 75% load in a 150 MW thermal power plant varies from 3% to 4% and for the case of a 350 MW power plant the energy consumption of the auxiliaries represents 2 to 3.5%. Nowadays this consumption are above 6%. Considering that the country has 40 units with capacities varying from 150 to 350 MW, the economical and the fuel saving would be substantial. This paper will present a summary of the methodology to be used to carry out this type of projects. [Espanol] Una de las areas potenciales de ahorro de energia en centrales termoelectricas son los sistemas auxiliares, de tal manera que basados en un diagnostico energetico preliminar y considerando que se aplicarian las medidas de ahorro de energia que van desde la instrumentacion, cambios operativos en equipos, asi como el uso de variadores de velocidad en motores, se tienen que los consumos de auxiliares para un 75% de carga en una central termoelectrica de 150 MW varian desde un 3% hasta un 4% y para el caso de una central termoelectrica de 350 MW, el consumo de auxiliares representa del 2 al 3.5%. Hoy en dia dichos consumos estan por encima del 6%. Si consideramos que el pais cuenta con 40 unidades que varian desde 150 MW hasta 350 MW, entonces los ahorros economicos y de combustible serian impactantes.

    bupivacaína racémica a 0,5% asociada a opioides por vía epidural constituye una técnica anestésica utilizada en cesárea, sin embargo su toxicidad se pone en tela de juicio. La bupivacaína con exceso enantiomérico de 50%, presenta un menor cardio y neurotoxicidad. Se evaluó la eficacia de la bupivacaína racémica y de la bupivacaína con exceso enantiomérico de 50% a 0,5%, asociadas al sufentanil, por vía epidural en embarazadas sometidas a la cesárea. MÉTODO: Cincuenta embarazadas a término, sometidas a la cesárea electiva bajo bloqueo epidural, distribuidas en dos grupos, de acuerdo con el anestésico local usado: Grupo I - bupivacaína racémica a 0,5% con vasoconstrictor; Grupo II - bupivacaína con exceso enantiomérico de 50% (S75-R25 a 0,5% con vasoconstrictor. En los dos grupos el anestésico local (100 mg estuvo asociado al sufentanil (20 µg y el volumen total usado de la solución fue de 24 mL. Se evaluaron: la latencia del bloqueo sensitivo; nivel máximo del bloqueo sensitivo; grado del bloqueo motor; tiempo para la regresión del bloqueo motor; duración de la analgesia; efectos colaterales maternos y repercusiones neonatales. RESULTADOS: La latencia, el nivel máximo del bloqueo sensitivo, el grado del bloqueo motor y la duración de la analgesia fueron similares en los dos grupos; el tiempo para la regresión del bloqueo motor fue significativamente menor en el Grupo II. Los efectos colaterales ocurrieron con frecuencia similar en los dos grupos. Hubo ausencia de alteraciones cardiocirculatorias maternas y repercusiones neonatales. CONCLUSIONES: La bupivacaína racémica y la bupivacaína con exceso enantiomérico de 50%, por vía epidural, proporcionan una anestesia adecuada para la realización de la cesárea. La bupivacaína con exceso enantiomérico de 50%, es una alternativa promisoria para ese tipo de procedimiento, por presentar un menor tiempo para la regresión del bloqueo motor, lo que mucho se desea en la paciente obst

  19. Unusual Spinal Epidural Lipomatosis and Lumbosacral Instability

    2016-01-01

    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. PMID:27069704

    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.

    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. Performing 'blind' epidural steroid injection lacks target specificity that often results in incorrect delivery of medication to the lesion. Imaging-guided steroid injections are now becoming more popular despite the controversy regarding their efficacy. Many reports, including a few randomized controlled trials, have documented the clinical utility of epidural steroid injections.

    Lumbar radiculopathy is generally caused by such well-recognized entity as lumbar disc herniation in neurosurgical practice; however rare pathologies such as thrombosed epidural varix may mimic them by causing radicular symptoms. In this case report, we present a 26-year-old man with the complaint of back and right leg pain who was operated for right L4-5 disc herniation. The lesion interpreted as an extruded disc herniation preoperatively was found to be a thrombosed epidural varix compressing the nerve root preoperatively. The nerve root was decompressed by shrinking the lesion with bipolar thermocoagulation and excision. The patient's complaints disappeared in the postoperative period. Thrombosed lumbar epidural varices may mimic lumbar disc herniations both radiologically and clinically. Therefore, must be kept in mind in the differential diagnosis of lumbar disc herniations. Microsurgical techniques are mandatory for the treatment of these pathologies and decompression with thermocoagulation and excision is an efficient method.

    Spinal epidural hematoma is an accumulation of blood in the potential space between the dura and bone. On unenhanced computed tomography epidural hemorrhage appears as a high-density spinal canal mass with variable cord compression. Magnetic resonance imaging is the modality of choice for evaluating spinal epidural hematoma and can demonstrate the extent of the hematoma and degree of cord compression. When treated surgically the outcome depends on the extent of preoperative neurological deficits and on the operative timing interval. (orig.) [German] Das spinale epidurale Haematom ist eine Blutansammlung zwischen Dura und Knochen. Die klinische Praesentation ist aehnlich dem akuten Bandscheibenvorfall, die Symptomatik ist allerdings in der Regel progredient. In der CT stellt sich ein frisches Haematom hyperdens dar. Die MRT ist die Methode der Wahl zur Diagnose spinaler epiduraler Haematome und kann die Ausdehnung sowie auch das Ausmass der Kompression darstellen. Die wichtigste Differenzialdiagnose vom epiduralen Haematom ist das epidurale Empyem. (orig.)

    Full Text Available An 8-month-old male infant had presented with a history of a fall from the crib a fortnight ago. He had developed progressive weakness of both lower limbs. On examination, the infant had spastic paraplegia. Magnetic resonance (MR imaging of the cervical spine showed an epidural hematoma extending from the fourth cervical (C4 to the first dorsal (D1 vertebral level with cord compression. The patient had no bleeding disorder on investigation. He underwent cervical laminoplasty at C6 and C7 levels. The epidural hematoma was evacuated. The cervical cord started pulsating immediately. Postoperatively, the patient′s paraplegia improved dramatically in 48 hours. According to the author′s literature search, only seven cases of post-traumatic epidural hematoma have been reported in pediatric patients, and our patient is the youngest. The present case report discusses the etiopathology, presentation, and management of this rare case.

    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 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.

    2006-05-01

    Full Text Available La incidencia de lesiones neurológicas de miembros inferiores en la práctica obstétrica es del 0,08% y 0,92%. La incidencia de complicaciones neurológicas asociadas a la técnica epidural ha sido estimada en 2 casos de cada 10.000 epidurales. Durante los últimos años, con la generalización de la analgesia epidural para el trabajo de parto, es posible que algunas de las neuropatías sean atribuidas a esta técnica, olvidando que hay otros mecanismos de lesión en estas situaciones. Presentamos el caso de una paciente primigesta de 21 años de edad y 139 cm de altura sin antecedentes de interés, que 24 horas tras una epidural para parto y un expulsivo prolongado resuelto con fórceps, desarrolla un "pie caído", que evolucionó a la resolución funcional completa. El pie caído puede darse como consecuencia de una lesión del nervio peroneo, del ciático, o de una raíz del plexo lumbo-sacro. La clínica unida al uso de pruebas como la resonancia magnética (RNM y el electromiograma (EMG, ayudan en el diagnóstico diferencial de la lesión. Parece necesario el estudio del las neuropatías relacionadas con el parto para descartar su relación con la técnica anestésica empleada. Con frecuencia, estas lesiones se deben a mecanismos ajenos a la analgesia-anestesia epidural, si bien debemos procurar minimizar su incidencia con la realización de punciones a niveles adecuados, evitando la inyección de anestésicos cuando existen parestesias, valorando los factores de riesgo en obstetricia y, una vez producida la lesión, con un seguimiento clínico estrecho.Postpartum neurological damage occurs in the obstetric practice with an incidence between 0.08-0.92%. Neurological damage secondary to epidural technique is about 2:10,000. In last years, epidural anesthesia has become a generalized practice in obstetrics. Because of it, sometimes, the postpartum neurological damage can be attributed to epidural analgesia, forgetting other mechanisms. We

    We present a case of a patient with a spinal epidural abscess (SEA) and meningitis following short-term epidural catheterisation for postoperative pain relief after a laparoscopic sigmoid resection. On the fifth postoperative day, 2 days after removal of the epidural catheter, the patient developed high fever, leucocytosis and elevated C reactive protein. Blood cultures showed a methicillin-sensitive Staphylococcus aureus infection. A photon emission tomography scan revealed increased activity of the spinal canal, suggesting S. aureus meningitis. A gadolinium-enhanced MRI showed a SEA that was localised at the epidural catheter insertion site. Conservative management with intravenous flucloxacillin was initiated, as no neurological deficits were seen. At last follow-up, 8 weeks postoperatively, the patient showed complete recovery.

    Postoperative epidural hematomas developed far from the operative field are generally recognized as a complication of ventriculo-peritoneal shunt, ventricular drainage or suboccipital craniotomy. It is very rare but may occur after supratentorial craniotomy on the contralateral side. Five such cases are presented with a review of the relevant literature. The mechanism of this complication is not clearly understood. In hydrocephalus, these massive epidural hematomas are probably caused by dura-skull detachment when the brain volume is strikingly reduced by a decompressive procedure. On rare occasions, pins of head rest may detach the dura and cause epidural hematomas. When sudden brain swelling during craniotomy is encountered, attention should be directed not only to intracerebral hemorrhage but also epidural hematoma developed on the contralateral side.

    Background Epidural lidocaine can be used when regional anesthesia needs to be established quickly,but the effect of co-administering epidural fentanyl on the minimum local analgesic concentration(MLAC)of lidocaine is not known.We compared the MLAC of epidural lidocaine in combination with different doses of fentanyl for epidural anesthesia in adults.Methods One hundred and twenty patients requiring epidural analgesia were randomly allocated to receive 20 ml of one of four solutions:lidocaine,or lidocaine plus fentanyl 1 μg/ml,2 μg/ml,or 3 μg/ml.The first patient in each group was administered 1% lidocaine weight by volume;subsequent patients received a concentration determined by the response of the previous patient to a higher or lower concentration according to up and down sequential allocation in 0.1% increments.Efficacy was assessed using a visual analog pain scale,and accepted if this was ≤10 mm on a 100 mm scale within 30 minutes.The extent of motor block and of nausea and vomiting were recorded at 30 minutes after administration of the epidural solution and two hours after surgery,respectively.Results The MLAC of lidocaine in those receiving lidocaine alone was 0.785%(95%C/0.738-0.864).A significant dose-dependent reduction was observed with the addition of fentanyl:the MLAC of lidocaine with fentanyl at 2 μg/ml was 0.596%(95%Cl 0.537-0.660)and 0.387% with fentanyl at 3 μg/ml(95%Cl 0.329-0.446,P<0.001).Conclusion Epidural fentanyl significantly reduces the dose of lidocaine required for effective epidural analgesia in adults without causing adverse side effects.

    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.

This study aimed at determining incidence, type and severity of postoperative complications related to epidural analgesia and catheter insertion. METHODS: Participated in this retrospective study 469 patients submitted to postoperative epidural analgesia in the period 10/18/99 to 10/18/01. Epidural analgesia was induced with 0.1% bupivacaine and fentanyl (1 to 5 µg.mL-1, at a 3 mL.h-1 rate. Infusion rate was adjusted according to patients' pain complaint. The following variables were evaluated: epidural infusion duration; incidence of side-effects and complications related to demographics, type of surgery and epidural catheter position; and quality of analgesia by means of a pain visual analog scale and a patients' satisfaction index. RESULTS: Epidural catheters remained in place 2.2 days in average, varying from 6 to 10 days. Global rate of technique-related complications was 46.3%, most of them minor complications without clinical repercussion. From these, 13.9% were directly related to the epidural catheter (disconnection, externalization, low back pain, inflammation and local infection. Other common complications were vomiting and urinary retention. Postoperative analgesia was effective in 97.2% of the patients which referred satisfaction with the technique. Patients without pain or slight pain during the first, second and third postoperative day represented 80.1%, 92.8% and 93.3%, respectively, of the studied population. CONCLUSIONS: Continuous epidural analgesia is effective and safe. Complications were not severe. However

    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.

    Objective: To demonstrate five discal cysts with detailed magnetic resonance imaging findings in nonsurgical and following postoperative microdiscectomy. Materials And Methods: Five discal cysts in four patients who underwent magnetic resonance imaging were found through a search in our database and referral from a single orthopedic spine surgeon. Computed tomography in two cases and computed tomography discography in one case were also performed. Results: Five discal cysts were present in four patients. Three patients had no history of previous lumbar surgery and the other patient presented with two discal cysts and recurrent symptoms after partial laminectomy and microdiscectomy. All were oval shaped and seated in the anterior epidural space. Four were ventrolateral, and the other one was centrally positioned in the anterior spinal canal. One showed continuity with the central disc following discography. Three were surgically removed. Conclusion: Magnetic resonance imaging can easily depict an epidural cyst and the diagnosis of a discal cyst should be raised when an homogeneous ventrolateral epidural cyst contiguous to a mild degenerated disc is identified.

    The formation of spinal epidural abscess following acupuncture is very rare. We herein report the case of a 54-year-old woman who presented with progressive low back pain and fever with a root sign. She underwent surgical decompression, with an immediate improvement of the low back pain. A culture of the epidural abscess grew Serratia marcescens. One year postoperatively, magnetic resonance imaging revealed the almost complete eradication of the abscess. This case is the first case of Serratia marcescens-associated spinal epidural abscess formation secondary to acupuncture. The characteristics of spinal epidural abscess that develop after acupuncture and how to prevent such complications are also discussed.

    This work relies on the development of a sensorized medical needle with an all-optical guidance (Lab in a Needle) system for epidural space identification. The device is based on the judicious integration of a Fiber Bragg grating sensor inside the lumen of an epidural needle to discriminate between different types of tissue and thus providing continuous and real time measurements of the pressure experienced by the needle tip during its advancement. Experiments carried out on an epidural training phantom demonstrate the validity of our approach for the correct and effective identification of the epidural space.

    Under general anaesthesia and muscle relaxation, a thoracic epidural catheter was inserted at the T8-T9 level in a 7-year-old boy scheduled to have a Nissen fundoplication to provide postoperative analgesia. After 4 ml of lignocaine 1.5% was injected through the catheter, hypotension resulted. Fifty-five minutes later 5 ml of bupivacaine 0.25% produced the same effect. In the recovery room a similar injection resulted in lower blood pressure and temporary apnoea. Sensory and motor deficits were noted the next day and four days later magnetic resonance imaging demonstrated spinal cord syringomyelia extending from T5 to T10. Four years later, dysaesthesia from T6 to T10 weakness of the left lower extremity and bladder and bowel dysfunction persist. The risks of inserting thoracic epidural catheters in patients under general anaesthesia and muscle relaxation are discussed, emphasising the possibility of spinal cord injury with disastrous consequences.

    The authors report a case of thrombosis of the distal end of an enlarged right posterior epidural vein. The patient had a markedly narrow lumbar canal due to L5 spondylolisthesis. The dilated vein and the thrombosis were displayed by computed tomography but remained unrecognized until surgery. Pathogenesis of this condition is discussed. A review of the English, French and German literature revealed no prior radiological reports of a similar condition.

    el grupo Propofol, sin embargo, la intensidad y duración de la sedación fueron mayores en ese grupo en relación al grupo Sufentanil. Los escores de recuperación fueron similares en los dos grupos. Después de 3 horas en la SRPA, todos los pacientes habían llegado a los criterios de transferencia para las enfermarías. Hipotensión arterial transitoria fue observada en 2 pacientes del grupo Sufentanil. CONCLUSIONES: La combinación de la anestesia peridural torácica continua con ropivacaína a 0,2% (1,5 ml.kg-1 asociada a la infusión de propofol promueve anestesia efectiva y segura para cirugías abdominales altas en niños. El ritmo de infusión de propofol y el tiempo de sedación fueron reducidos con la adición de sufentanil.BACKGROUND AND OBJECTIVES: Several anesthetic techniques have been proposed for different pediatric surgeries to promote postoperative analgesia, among other advantages. This study aimed at evaluating propofol infusion rate and postanesthetic recovery of children submitted to upper abdominal surgeries under epidural anesthesia with 0.2% ropivacaine associated to general anesthesia with propofol or propofol plus sufentanil. METHODS: Participated in this study 26 children physical status ASA I, II and III, aged 0 to 4 years, were scheduled to upper abdominal surgeries under thoracic epidural anesthesia (T7-T8 with 0.2% ropivacaine (1.5 ml.kg-1. They were randomly distributed in two groups: Propofol (propofol infusion and Sufentanil (propofol infusion plus 1 µg.kg-1 sufentanil. Propofol infusion rates were 20 and 10 mg.kg-1.h-1 for the Propofol and Sufentanil groups, respectively, adjusted to maintain blood pressure in approximately 20% of baseline values and withdrawn 10 to 15 minutes before estimated surgery completion. Postanesthetic recovery was evaluated by a modified Aldrete-Kroulik scale and sedation was evaluated by a 5 grade score. RESULTS: Techical difficulties excluded two children of each group.

    Full Text Available Pectoralis minor blocks are still relatively new and require further evaluation, but may have a place in peri-operative pain management for the appropriate cases. Still considered as less invasive procedure in comparison to thoracic epidurals and para-vertebral blocks. Complications of thoracic epidural and para-vertebral blocks like spinal cord injury and pneumothorax makes many anaesthetists interested in practising pectoralis minor block guided by ultrasound. Blanco first introduced the pectoralis minor block in 2011, he did study on 50 patients within 2 years. Results were very promising, all patients did not need any opiates but only paracetamol and non-steroidal anti-inflammatory (NSAID drugs got used.

    Eleven healthy pregnant women were studied to determine temperature changes after induction of epidural anesthesia during cesarean delivery. Epidural anesthesia was induced by 2% lidocaine 15-20 ml (T 5 level) at 25 degrees C ambient temperature. Tympanic membrane and skin surface temperature, skin-temperature gradients (forearm-fingerchip, calf-toe), thermal perception (1-10 scale VAS) and the presence or absence of shivering were measured. Sixty minutes after induction, tympanic temperature decreased for 0.52 +/- 0.26 degrees C and average skin temperature increased for 0.56 +/- 0.17 degrees C. Central hypothermia and shivering did not produce a cold sensation. Temperature gradients of upper limb increased to 2.0 +/- 3.7 degrees C (50 minutes after induction) and the lower limbs decreased to -1.4 +/- 0.55 degrees C (30 minutes after induction). Shivering occurred in 3 patients. We conclude that epidural anesthesia impaired thermoregulatory control and induced redistribution hypothermia as in nonpregnant individuals.

    Pyogenic spinal epidural abscess Is an uncommon Infectious occurrence. Clinical prospects of pyogenic spinal epidural abscess are graver if not promptly diagnosed and treated appropriately. A case of spinal epidural abscess has been presented with sinus tract formation at L4-L5 level, of pyogenic aetiology that progressed to paraplegia over the course of the disease. MRI pointed towards an epidural abscess extending from T12 vertebral level to S1 vertebral level. Surgical decompression in the form of laminectomy and evacuation of pus was done and antibiotics were given according to culture and sensitivity. Histopathological analysis revealed the acute suppurative nature of the abscess. Citrobacter kasori was isolated on pus culture. Pyogenic epidural abscess with causative organism being Citrobacter kasori has least been documented.

    Acute epidural hematoma not associated with head injury is rarely encountered and is known as spontaneous epidural hematoma. To our knowledge, only five cases with epidural hematoma after open-heart surgery have been published. Pathogenesis and preventive measures have not yet been determined. We report a case of such spontaneous epidural hematoma and consider the possible pathogenesis. A 12-year-old female received a radical operation for severe subaortic stenosis. The intraoperative course was uneventful except for massive hemorrhage which was adequately controlled. Postoperatively, she was moved to the CCU still not having aroused from anesthesia. Eleven hours later, it was found that her pupils were fixed and dilated. CT scan demonstrated a huge bifrontal epidural hematoma with disappearance of the basal cistern. Even though immediate emergency evacuation was performed, the patient died of acute brain swelling four days after the operation.

    Spinal epidural abscess is a rare infectious disease. However, if left unrecognized and untreated, the clinical outcome of spinal epidural abscess can be devastating. Correctly diagnosing a spinal epidural abscess in a timely fashion is often difficult, particularly if the clinician does not actively consider the diagnosis. The most common presenting symptoms of spinal epidural abscess include backache, radicular pain, weakness, and sensory deficits. However, early in its course, spinal epidural abscess can also present with vague and nondescript manifestations. In this report, we describe a case of spinal epidural abscess presenting as abdominal pain, and review the literature describing other cases of spinal epidural abscess presenting as intra-abdominal pathology.

    Full Text Available Streamflows in five Mediterranean mountain headwaters in the central Spanish Pyrenees were projected under various climate and land use change scenarios. Streamflows were simulated using the Regional Hydro-Ecologic Simulation System (RHESSys. The results show that changes in precipitation and temperature could cause a decline of annual streamflow between 13% and 23%, depending on the considered catchment. When the effect of increased forest cover in the basins is added to climate change effects, the decrease in annual streamflow is enhanced up to 19% and 32%. The largest hydrological changes resulting from environmental change are projected mainly in early spring, summer and autumn, when the decline may exceed 40%. Winter is the least affected season by environmental change because of increased runoff as a consequence of reduced storage of water in the snowpack and an earlier onset of the snowmelt, and the lower consumption of water by vegetation during the cold season. The magnitude of hydrological change as a result of the assumed environmental change scenarios may lead to serious impacts on water management and ecology of the studied region, as well as the water availability in the Ebro basin.Se han simulado los caudales de cinco cabeceras de ríos en los Pirineos centrales españoles, considerando diferentes escenarios de cambio climático y de uso del suelo. Los caudales fueron simulados utilizando el modelo hidroecológico RHESSys (Regional Hydro-Ecologic Simulation System. Los resultados muestran que los cambios proyectados por un conjunto de modelos climáticos regionales en precipitaciones y temperaturas en el siglo XXI podrían causar una disminución del caudal anual entre el 13% y el 23%, dependiendo de la cuenca considerada. Cuando se añade a los efectos del cambio climático el efecto del aumento de la cubierta forestal en las cuencas, la disminución de los caudales anuales oscila entre el 19% y el 32%, dependiendo de la cuenca

    Full Text Available Abstract Background Bacteria in the Streptococcus milleri group (S. anginosus, S. constellatus, and S. intermedius are associated with bacteremia and abscess formation. While most reports of Streptococcus milleri group (SMG infection occur in patients with underlying medical conditions, SMG infections during pregnancy have been documented. However, SMG infections in pregnant women are associated with either neonatal or maternal puerperal sepsis. Albeit rare, S. milleri spinal-epidural abscess in pregnancy has been reported, always as a complication of spinal-epidural anesthesia. We report a case of spinal-epidural abscess caused by SMG in a young, pregnant woman without an antecedent history of spinal epidural anesthesia and without any underlying risk factors for invasive streptococcal disease. Case presentation A 25 year old pregnant woman developed neurological symptoms consistent with spinal cord compression at 20 weeks gestation. She underwent emergency laminectomy for decompression and was treated with ceftriaxone 2 gm IV daily for 28 days. She was ambulatory at the time of discharge from the inpatient rehabilitation unit with residual lower extremity weakness. Conclusion To our knowledge, this is the first reported case of a Streptococcus milleri epidural abscess in a healthy, pregnant woman with no history of epidural anesthesia or invasive procedures. This report adds to the body of literature on SMG invasive infections. Treatment of SMG spinal-epidural abscess with neurologic manifestations should include prompt and aggressive surgical decompression coupled with targeted anti-infective therapy.

    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.

    Full Text Available Posterior epidural migration (PEM of a sequestered free lumbar disc fragment is rare. The rarity is due to presence of several anatomical restraints which restrict a free fragment to move to the posterior compartment. This unusual presentation of disc herniation appeared in the literature either as a single case report or in small series from two to six cases. Herein two new demonstrative cases will be presented with a brief review of the literature.La migración epidural (PEM posterior Epidural Migration de fragmento de disco lumbar libre secuestrado es rara.

    Full Text Available Central neuraxial blocked is one of the safest and efficacious methods of anaesthesia and analgesia. It has the added advantage of prolonged pain relief into the postoperative period. Epidural analgesia has increased steadily in popularity when compared to spinal anaesthes ia due to its neurological consequences and improved post - operative analgesia with epidural Opioids and as a consequence decreased side effects and prolonged the duration of analgesia. Present study is undertaken to compare hemodynamic and analgesic charac teristics using a 0.75% ropivacaine to a conventional dose of 0.5% bupivacaine for cesarean section under epidural anaesthesia. This study was conducted in ASA Grade I 50 singleton parturient to compare hemodynamics, APGAR scores and analgesic characterist ics of ropivacaine and bupivacaine. We have observed that the onset of sensory blockade was slower with ropivacaine and the duration of sensory blockade was also less. Whereas there was no significant change in haemodynamics and APGAR scores with both the drugs.

    Horner syndrome is rarely observed in connection with epidural anesthesia. It is characterized by ptosis, enophthalmos, miosis, anisocoria, and conjunctival hyperemia in the affected eye, as well as anhydrosis and flushing on the affected side of the face. It is usually a complication spontaneously resolved without permanent neurological deficits. Intraoral anesthesia; stellate ganglion, cervical or brachial plexus blocks; thoracic, lumbar or caudal epidural anesthesia, and intrapleural analgesia are the main causes for Horner syndrome related to anesthesia. Among other causes of Horner syndrome are head and neck surgery, trauma, and puncture of internal jugular vein. The present case of unilateral Horner syndrome appeared in the aortobifemoral bypass after lumbar spinal- epidural anesthesia.

    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.

    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.

    Full Text Available We conducted a study to compare the efficacy and safety of Patient Controlled Epidural Analgesia (PCEA with that of Continuous Infusion of Epidural Analgesia (CIEA for maintenance of labour analgesia and evaluated the quality of analgesia and obstetric and safety outcomes. METHODS The study was a hospital-based prospective, randomised control trial on 80 parturients who had a normal antenatal period. Each parturient received 500-1000 mL lactated ringer solution Intravenously (IV prior to initiating epidural blockade. Epidural catheter placement was performed in a standard manner and all patients received an initial dose of 8-10 mL bupivacaine 0.25%. Parturients self-administered 0.125% bupivacaine with fentanyl 2.5 µg/mL using PCA pumps programmed as follows: 4 mL bolus with a 20 mins Lockout Interval (LI. Group B received CIEA of 8 mL 0.125% bupivacaine with fentanyl 2.5/mL. Hourly assessments included: VAS scores for pain and satisfaction, sensory and motor block, analgesic supplements, bupivacaine and fentanyl consumption. RESULTS Data from 80 patients showed no differences among groups in pain relief. Maternal satisfaction was greater in PCEA group. Anaesthetic interventions by way of supplemental doses of Bupivacaine and Fentanyl in the PCEA group were minimal (4 and 2 vs 25 and 12 P <0.001 compared to CEI group. PCEA group received less local anaesthetic (5.2 vs 9.4 p <0.001 and few patients in PCEA group had motor weakness compared to CEI group (6 vs 17 p <0.05. Both methods were safe for mother and newborn. CONCLUSION Patients who received PCEA required less anaesthetic interventions, required lower doses of local anaesthetic, fentanyl and have less motor weakness than those who received CEI.

    Our purpose was to determine if specific MRI findings in spinal epidural abscess (SEA), at the time of diagnosis, are associated with the clinical outcome. The clinical records and MRI studies of 18 patients with SEA were reviewed and follow-up was obtained from the outpatient medical record, telephone interview, or both. The association between findings on contrast-enhanced MRI and clinical outcome (weakness, neck or back pain, and incomplete functional recovery) was evaluated. With univariate analysis, narrowing of 50 % or more of the central spinal canal (P = 0.03), peripheral contrast-enhancement (P = 0.05), and abnormal spinal cord signal intensity (P = 0.05) were associated with weakness at follow-up. Persistent neck or back pain was associated with spinal canal narrowing (P = 0.02), peripheral contrast-enhancement (P = 0.02), and an abscess longer than 3 cm (P = 0.04) on MRI. Incomplete clinical recovery was associated with both abscess length (P = 0.01) and the severity of canal narrowing (P = 0.01). Abscess length, enhancement pattern, and severity of canal narrowing can be incorporated in a grading system that can be used to predict outcome. (orig.)

    Spinal epidural lipomatosis (SEL) is the abnormal accumulation of normal fat within the spinal canal. It is more frequent in those patients receiving chronic glucocorticoid therapy or in cases of endogenous hypercortisolism states. We report a case of SEL in a patient with metastatic prostate cancer with history of steroid treatment as part of his chemotherapy regimen, presenting with clinical manifestations of partial cord compression. Magnetic resonance imaging images of the lumbar spine revealed the presence of epidural tumor suspicious for metastatic disease. Operative findings were consistent with epidural lipomatosis. Spinal epidural lipomatosis is a rare condition that needs to be included in the differential diagnosis of patients with risk factors, presenting with symptomatic cord compression.

    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.

    Vacuum disc phenomenon is a collection of gas in the intervertebral disc space but rarely causes nerve compression. However, some rare type of vacuum phenomenon in the spinal canal may bring about posterior gas displacement within the epidural space. The authors describe two patients with symptomatic epidural gas-containing cyst that seem to be originating from vacuum phenomenon in the intervertebral disc, causing lumbosacral radiculopathy. Radiographic studies demonstrated intervertebral vacuum phenomenon and accumulation of gas in the lumbar epidural space compressing the dural sac and the nerve root. The nerve root in both patients was compressed by gas containing cyst that was surrounded by thin walled capsule separable from the gaseous degenerated disc space. The speculative mechanism of the nerve root compression is discussed. The possibility of gas containing cyst should be considered in case of the nerve root compression in which epidural gas is present.

    Combined spinal epidural block has proven its efficacy in skilled hands. This technique allies advantages of spinal anaesthesia, regarding its speed of action and intensity of motor blockade and advantages of postoperative epidural analgesia. This block must be performed with great care and method to reach a success rate of almost 100%. Local anaesthetics and additives are reviewed and commented. The two main complications, hypotension and post dural puncture headache can be contained in very low limits.

    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.

This study was designed to compare combined spinal eqidural (CSE versus epidural block using a narcotic (sufentanil and local anaesthetic bupivacaine regarding their effects on progress of labour, method of delivery, pain relif, side effects and neonatal outcome. Patients and Methods :-Forty pregnant women ASA I and II were enrolled in this study. The women were randomly allocated to receive either CSE or epidural ( 20 patient of each . In CSE group analgesia was initiated with 10ug sufentanil with 2mg bupivacaine. In epidural group 10ml bupivacaine 0.125%.and 10ug sufentanil injected epidurally. In both groups the continuous infusion of 0.83% bupivacaine with 0.33ug/ml sufentanil at 10ml/hr adjusted as required. Maternal haemodynamics, analgesia characteristics VAPS, degree of motor block, were measured. Duration of labour, cervical dilation, maternal satisfaction and mode of delivery were assessed. Foetal outcome was assessed by 1 and 5 min. Apgar score and umbilical venous blood gases. Maternal and neonatal side effects were observed. The experimental study was done on 30 rats divided into 3 groups 10 rats of each. Control group (A injected intrathecally with saline, group (B injected intrathecally with 1.5ug/kg sufentanil (low dose, and group (C injected intrathecally with 7.5ug/kg sufentanil (high dose, the pervious doses were injected every 2hr. for 3 times then the spinal cord was obtained and stained for histological evaluation. Results:- The clinical study showed that no difference between the 2 groups for the degree of motor block or adequacy of analgesia, mode of delivery and Foetal outcome. The onset of analgesia was faster with CSE technique, more patient satisfaction and more pruritis. The histological results revealed that no detectable significant neurotoxic changes with the use of small dose of intrathecal sufentanil but mild changes occurred with high

    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.

  8. Epidural fibrosis after permanent catheter insertion and infusion.

    Forty-six permanent epidural catheters and life-port units were implanted in 43 patients with severe, recurrent low back pain who had been considered not to be candidates for surgical intervention and in whom other therapeutic modalities had failed. Eight cases developed epidural fibrosis (EF). For analgesia, patients received either infusions with preservative-free solutions of fentanyl and bupivacaine or daily boluses of morphine and bupivacaine. Catheters remained from 75 days to 433 days. Signs of EF appeared from 21 days to 320 days after implantation. Pain at injection or resistance to injection were initial manifestations of EF, followed by poor, and eventually, nil analgesic effect. The epidural catheters were made of either polyamide, silicone, or polyurethane. Epidurograms revealed encapsulation, narrowing, and loculation of epidural space with gradually reduced spread of the contrast material. The occurrence of EF limits the permanency of implanted epidural catheters. The infusate does not cause this complication, which appears to be a foreign body reaction due to the presence of the catheter in the epidural space.

    2013-01-01

    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.

    Spinal epidural abscess (SEA) is a rare clinical condition among children. Most patients do not present with classical signs. A 13-year-old boy without any predisposing factors presented with paraparesis, bladder and bowel involvement. MRI spine demonstrated an SEA at the C7 and D1 levels on both sides of the midline with cord oedema at the C2-3 to C6 level with minimal marrow oedema in the C6 vertebral body. We treated the patient with antibiotics (ceftriaxone and vancomycin) alone. The patient showed excellent response with only minimal residual gait disturbance at the end of 6 weeks of antibiotic therapy. This is the first paediatric report of complete recovery of a patient at clinical stage 4 following antibiotic treatment alone from India. However, caution should be exercised to closely monitor the patient's recovery as any progression in the neurological state warrants surgery.

Objetivo: Comparar la incidencia de complicaciones, durante la punción, en el curso del bloqueo, como consecuencia de una analgesia incompleta y evaluar las diferencias que existen entre el día y la noche definiendo día como el periodo entre 9:00 y 21:59 h y noche: de 22:00 a 8:59 h. Material y métodos: Hemos realizado un estudio de los bloqueos recogidos en nuestra base de datos informatizada de pacientes a quienes se practicó algún bloqueo central para analgesia del parto realizados en un hospital universitario de grado 4, con atención durante las 24 horas, durante un periodo de 2 meses. Resultados: Se ha estudiado un total de 1097 pacientes, homogéneas en su distribución (variables demográficas y obstétricas, entre el día y la noche. El número de pacientes a las que se les practica un bloqueo analgésico para trabajo de parto no muestra diferencias entre el día y la noche. No hemos encontrado diferencias en la incidencia de complicaciones en la punción ni de analgesia incompleta, deficiente o necesidad de re-punción. Conclusiones: Parece que el cansancio o la falta de sueño no influyen en la incidencia de complicaciones en la analgesia para el trabajo de parto en una unidad de atención las 24 horas. Probablemente, los médicos se ven incentivados por la realización de una tarea interesante.Introduction: Sleep deprivation effects in vigilance, performance and complications have been previously studied in general population and in medical tasks too.

    Introduction Hematoma associated with epidural catheterization is rare, but the diagnosis might be suspected relatively frequently. We sought to estimate the incidence of suspected epidural hematoma after epidural catheterization, and to determine the associated cost of excluding or diagnosing an epidural hematoma through radiologic imaging. Methods We conducted an electronic retrospective chart review of 43,200 patient charts using 4 distinct search strategies and cost analysis, all from a single academic institution from 2001 through 2009. Charts were reviewed for use of radiological imaging studies to identify patients with suspected and confirmed epidural hematomas. Costs for imaging to exclude or confirm the diagnosis were related to the entire cohort. Results In our analysis, over a 9-year period that included 43,200 epidural catheterizations, 102 patients (1:430) underwent further imaging studies to exclude or confirm the presence of an epidural hematoma—revealing 6 confirmed cases and an overall incidence (per 10,000 epidural blocks) of epidural hematoma of 1.38 (95% CI 0, 0.002). Among our patients, 207 imaging studies, primarily lumbar spine MRI, were performed. Integrating Medicare cost expenditure data, the estimated additional cost over a 9-year period for imaging and hospital charges related to identifying epidural hematomas nets to approximately $232,000 or an additional $5.37 per epidural. Discussion About 1 in 430 epidural catheterization patients will be suspected to have an epidural hematoma. The cost of excluding the diagnosis, when suspected, is relatively low when allocated across all epidural catheterization patients. PMID:23924685

    Full Text Available La analgesia epidural se ha convertido en una técnica rutinaria en el manejo perioperatorio de los pacientes quirúrgicos que se ha extendido fuera de los quirófanos y de las unidades de alta dependencia hacia las salas de hospitalización. La irrupción en este nuevo escenario ha mejorado la analgesia postoperatoria con aceptables márgenes de seguridad, lo que le ha servido para colocarse en un lugar predominante entre las pautas analgésicas de las Unidades de Dolor Agudo (UDA. La analgesia epidural con anestésicos locales y opioides frente a la sistémica con opioides ha presentado históricamente una superior eficacia analgésica, y una disminución de complicaciones derivadas de la atenuación del estrés quirúrgico y de la mejora en la función cardiorrespiratoria. Sin embargo, frente a estas ventajas la analgesia epidural también presenta inconvenientes como la hipotensión arterial o la retención urinaria, junto a las potencialmente graves derivadas del daño neurológico ocasionado por un hematoma epidural, una infección o una lesión directa del tejido nervioso. Si sus ventajas han resultado consistentes y fundamentadas, en este momento no lo parecen tanto. El avance que ha supuesto la cirugía mínimamente invasiva con altas más precoces, junto al desarrollo de estrategias multimodales, está conduciendo a un replanteamiento de la utilización de técnicas como la epidural y a una reevaluación de sus indicaciones. Las últimas evidencias nos inducen a pensar que la epidural probablemente haya tocado techo en el tratamiento del dolor postoperatorio y comenzará a perder terreno frente a otras técnicas igualmente efectivas, con menores complicaciones y efectos secundarios. Este será un proceso lento en el que deberá quedar asegurado que las alternativas analgésicas ofrecen realmente mejores resultados en cuanto a eficacia, seguridad, tolerabilidad y calidad de la recuperación desde la perspectiva del paciente.

Para tanto, foram utilizadas 20 cadelas e 129 filhotes distribuídos em quatro grupos. No grupo 1 (5 cadelas e 39 neonatos, a indução anestésica foi feita com propofol; no grupo 2 (5 cadelas e 25 neonatos, com etomidato; no grupo 3 (5 cadelas e 26 neonatos com tiopental e no grupo 4, (5 cadelas e 39 neonatos utilizou-se anestesia epidural e indução com halotano através de máscara. Em todos os casos, a medicação pré-anestésica foi feita com midazolam na dose de 0,22mg kg-1 via IM, e a manutenção anestésica com halotano em circuito semifechado e concentração inicial de 3V%. As variáveis avaliadas nas cadelas foram: temperatura retal, freqüência cardíaca, freqüência respiratória, saturação da oxi-hemoglobina (SpO2, pressão arterial média. Para a avaliação dos recém-nascidos, foram mensurados: freqüência cardíaca, esforço respiratório, movimentos musculares, coloração das mucosas e irritabilidade reflexa interpretados através do escore de Apgar modificado, bem como a SpO2 do neonato. Os resultados mostraram que todos os protocolos foram adequados para as mães com mínimos efeitos sistêmicos. Para o neonato, a utilização de anestesia epidural na mãe, seguida de indução e manutenção com halotano foi superior aos protocolos que usaram agentes injetáveis na indução anestésica.

    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.

  1. EFFICACY OF TRANSFORAMINAL EPIDURAL STEROID INJECTION IN LUMBOSACRAL RADICULOPATHY

    2016-02-01

    Full Text Available BACKGROUND Lumbosacral radiculopathy is a common medical and socioeconomic problem with a lifetime prevalence estimated to be around 40%-60%. In 1930, Evans reported that sciatica could be treated by epidural injection. The use of epidural corticosteroid injection for the treatment of axial and radicular back pain was first reported in 1953. Lumbar Transforminal Epidural Steroid Injections (TFESIs are performed to provide symptomatic relief in patients with radicular pain. A transforaminal epidural steroid injection (TFESI using a small volume of local anaesthetic will anaesthetize the spinal nerve and also partially anaesthetize the dura, the posterior longitudinal ligament, the intervertebral disc and facet joint. For these reasons, fluoroscopy-guided TFESI has become the preferred approach to epidural space. AIMS AND OBJECTIVES To study the role of transforaminal epidural steroid injection in management of radiculopathy. SETTINGS AND DESIGN This prospective study was conducted in the Department of Orthopaedics, SKIMS Medical College and Hospital, Bemina, Srinagar, J and K, India, for a 2-year period from November 2012 to October 2014; 110 cases, both male and female in the age group of 20-60 years having back pain with radiculopathy of varied types and duration without neurodeficit were enrolled in the study. MATERIALS AND METHODS After selecting a patient for giving transforaminal block, we used a local anaesthetic (2% Xylocaine. Contrast media, e.g. Iohexol was used to demarcate the correct positioning of the needle. A spinal needle (20-25 gauge and 5mL syringe were used to deliver the drug. CONCLUSION Transforaminal epidural steroid injections with long acting anaesthetic is an excellent form of conservative treatment in management of low back ache with radicular pain. It is relatively safe, simple, economical and shortens the time of recovery from severe pain, avoids risks and complications of surgery and also avoids long periods of bed

    2005-02-01

    Full Text Available La historia de la anestesia intratecal y epidural ha discurrido en paralelo al desarrollo de la anestesia general. La primera reseña publicada sobre el uso de opioides para anestesia intradural la realizó un cirujano rumano, que presentó su experiencia en 1901 en París. Ha pasado casi un siglo hasta conseguir la utilización de opioides por vía epidural. En nuestros días, el uso de opioides intradurales y epidurales constituye una práctica clínica habitual para conseguir analgesia intra y postoperatoria. En los últimos 30 años, el uso de opioides epidurales se ha convertido en rutinario para el tratamiento del dolor del trabajo del parto y del manejo tanto del dolor agudo como crónico. Ha sido ampliamente asumido que cualquier opioide depositado en el espacio epidural o intratecal producirá una analgesia altamente selectiva medular y que esta será superior a la conseguida por otras técnicas analgésicas o vías de administración. Desafortunadamente esto simplemente no es verdad. De hecho, en multitud de ocasiones, los opioides son utilizados vía perimedular a pesar de que la evidencia clínica nos demuestra que no producen un efecto específico medular, o que la analgesia producida no es superior a la conseguida tras su administración intravenosa. Para realizar un uso apropiado de los opioides espinales, debemos comprender adecuadamente la fisiología y la farmacología clínica de estos fármacos y cuál produce analgesia selectiva medular y cuál no. Las diferencias son producto de la biodisponibilidad en los receptores específicos de su biofase medular en la sustancia gris. Esta es menor para los opioides lipofílicos, ya que son aclarados hacia el plasma con mayor rapidez que los hidrofílicos, y consecuentemente producen con mayor antelación efectos adversos supramedulares y su vida media es de menor duración. La morfina es probablemente el opioide con mayor acción selectiva medular tras su administración epidural o

    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.

    Under the expectations of expansion of electric power generation in Mexico, this work exposes the development of a conventional and intelligent generalized supervisory control (CSG) for a combined cycle generation power plant. This one allows to obtain the optimal operation of the power plant through the automatic starting of the generating units and to obtain the maximum possible amount of electrical power in automatic and safe form. For the development of the CSG a control loop by temperature was implemented for the gas turbine system and a control loop by strangled pressure for the gas turbine and a control loop by strangled pressure for the steam turbine. The design of these supervisory systems was made with base in the critical limits on the involved variables of the process: blading average temperature, for the gas turbine (GT) and strangled pressure for the steam turbine (ST) [Spanish] Bajo estas expectativas de expansion de generacion de energia en Mexico, este trabajo expone el desarrollo de un control supervisorio generalizado (CSG) para una central generacion de ciclo combinado.

    Epidural block is achieved either by single injection of local anesthetic through an epidural needle or as a continuous block by infusion pump through an epidural catheter. Complications associated with epidural catheters include breakage, entrapment, and knotting. Knotting of epidural catheters is very rare, but knotting in lumbar epidural catheters has been reported in a number of studies, and most of these cases involved removal difficulty. We report a case in which we inserted a cervical epidural catheter in a patient who was experiencing severe post-herpetic neuralgia and then removed the knotted catheter without complications.

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

    Spinal epidural abscess (SEA) is an uncommon and potentially catastrophic condition. SEA often presents a diagnostic challenge, as the "classic triad" of fever, spinal pain, and neurological deficit is evident in only a minority of patients. When diagnosis is delayed, irreversible neurological damage may ensue. To minimize morbidity, an appropriate level of suspicion and an understanding of the diagnostic evaluation are essential. Infection should be suspected in patients presenting with axial pain, fever, or elevated inflammatory markers. Although patients with no known risk factors can develop SEA, clinical concern should be heightened in the presence of diabetes, intravenous drug use, chronic renal failure, immunosuppressant therapy, or a recent invasive spine procedure. When the clinical profile is consistent with the diagnosis of SEA, gadolinium-enhanced magnetic resonance imaging of the spinal column should be obtained on an emergent basis to delineate the location and neural compressive effect of the abscess. Rapid diagnosis allows for efficient treatment, which optimizes the potential for a positive outcome.

    Full Text Available Background: In elective open infrarenal aortic aneurysm repair the use of epidural anesthesia and analgesia may preserve splanchnic perfusion. The aim of this study was to investigate the effects of epidural anesthesia on gut perfusion with gastrointestinal tonometry in patients undergoing aortic reconstructive surgery. Methods: Thirty patients, scheduled to undergo an elective infrarenal abdominal aortic reconstructive procedure were randomized in two groups: the epidural anesthesia group (Group A, n=16 and the control group (Group B, n=14. After induction of anesthesia, a transanally inserted sigmoid tonometer was placed for the measurement of sigmoid and gastric intramucosal CO 2 levels and the calculation of regional-arterial CO 2 difference (ΔPCO 2 . Additional measurements included mean arterial pressure (MAP, cardiac output (CO, systemic vascular resistance (SVR, and arterial lactate levels. Results: There were no significant intra- and inter-group differences for MAP, CO, SVR, and arterial lactate levels. Sigmoid pH and PCO 2 increased in both the groups, but this increase was significantly higher in Group B, 20 min after aortic clamping and 10 min after aortic declamping. Conclusions: Patients receiving epidural anesthesia during abdominal aortic reconstruction appear to have less severe disturbances of sigmoid perfusion compared with patients not receiving epidural anesthesia. Further studies are needed to verify these results.

    Full Text Available OBJECTIVE: Epidural (EA and combined spinal-epidural (CSE techniques have both been utilized for labor analgesia. This study compared the effects on the mother and newborn of these techniques in labor analgesia and anesthesia. METHODS: Forty pregnant women received epidural analgesia with 15 mL of 0.125% ropivacaine (EA group and 5 µg of sufentanil plus 2.5mg bupivacaine in the subarachnoid space (CSE group. Pain intensity, sensory blockade level, latency time, motor block intensity, labor analgesia duration, epidural analgesia duration, maternal hypotension, and pruritus were evaluated. The newborns were evaluated by Apgar and the neurological and adaptive capacity score (NACS developed by Amiel-Tison. RESULTS: There were no significant statistical differences between groups for pain scores, latency time, sensory blockade level, and Apgar score. Motor block, labor analgesia duration, and epidural analgesia duration were greater in the CSE group, whose seven mothers had mild pruritus. The NACS were greater in the EA group after half, two, and 24 hours. Ninety five percent of EA group newborns and 60% of CSE group newborns were found to be neurologically healthy at the 24 hour examination. CONCLUSION: EA and CSE analgesia relieved maternal pain during obstetric analgesia, but CSE mothers had pruritus and a longer labor. Newborns of mothers who received epidural analgesia showed the best NACS.OBJETIVO: A peridural (AP e a técnica de duplo bloqueio (DB são utilizadas em analgesia para o trabalho de parto.

They commonly arise as a result of direct extension of a preexisting infection and rarely present with focal deficit. We present a case of a 11-days old preterm infant who developed an intracranial epidural abscess as a result of an infected scalp vein catheter. The diagnosis was made on the basis of the cranial ultrasound and CT scan images. An identified strain of Enterococcus faecium was cultured from all the samples. The patient underwent a right frontal craniotomy with drainage of the abscess and a 2-week total course of intravenous antibiotics was administrated. CT scan imaging 3 week after the procedure demonstrated no evidence of residual lesion. When present, a scalp vein catheter, in absence of others predisponing factors, must be considered as an etiologic agent for an intracranial epidural abscess in this age-group.

    A 27-year-old man presented with a very rare spinal epidural mass associated with recurrence of acute lymphocytic leukemia (ALL) manifesting as acute progressive neurological deficits. The patient presented with shoulder pain and ambulatory difficulties 3 years after remission of ALL treated by bone marrow transplantation. Magnetic resonance imaging revealed an epidural mass extending from C-7 to T-3, which compressed the cord and extended to the intervertebral foramen along the roots. After decompression surgery, the symptoms dramatically improved. Histological examination showed clusters of immature lymphocytes consistent with recurrence of leukemia, so chemotherapy and radiation therapy were carried out. At 1 year after the operation, no local mass expansion or systemic progression of leukemia had occurred. Leukemic mass must be considered in the differential diagnosis of spinal epidural mass, even in patients with ALL.

    Background Cervicogenic headache (CEH) is caused by a structural abnormality in the cervical spine. Available treatments for CEH include medical therapy, local botulinum toxin injection, cervical epidural corticosteroid injection, and surgery. The objective of this study was to investigate the safety and efficacy of a continuous epidural block of the cervical vertebra.Methods Medical records were retrospectively analyzed for 37 patients diagnosed with CEH treated by a continuous epidural block of the cervical vertebra with lidocaine, dexamethasone, and saline (5 ml/min) for 3-4 weeks and triamcinolone acetonide 5 mg once weekly for 3-4 weeks. Pain was measured via the visual analogue scale (VAS) in combination with quality of life assessment. Outcome measures were patient-reported days with mild or moderate pain, occurrence of severe pain, and the daily oral dosages of non-steroidal anti-inflammatory drug use (NSAID).Results In the 3 months immediately preceding placement of the epidural catheter, the mean number of days with mild or moderate pain was 22.0±4.3. The mean occurrence of severe pain was (3.20±0.75) times and the mean oral dosage of NSAID was (1267±325) mg. During the first 6 months after epidural administration of lidocaine and corticosteroids, the mean number of days with mild or moderate pain, the mean occurrence of severe pain, and the mean daily oral dosages of NSAIDs were significantly decreased compared to 3-month period immediately preceding treatment (P <0.01). By 12 months post-treatment, no significant difference in these three outcome measures was noted.Conclusions Continuous epidural block of the cervical vertebra for patients with CEH is effective for at least six months. Further research is needed to elucidate mechanisms of action and to prolong this effect.

    Full Text Available BACKGROUND: Many drugs have been used to prolong analgesic effects of epidural local anesthetics. These are called adjuvants. We studied the epidural effect of Neostigmine when adminstered with Bupivacaine in comparison with Bupivacaine . OBJECTIVE: The objective for the study was to find a drug which enhances the onset of action, increases the duration of action of the local anesthetic with minimal or no side effects, instead of increasing the dose of local anaesthetic. MATERIALS AND METHODS: A prospecti ve study was conducted on 100 adult patients, selected at random of either sex, of age between 20 - 65 years and belonging to ASA grade I or II. The study was designed to compare the effects of epidural Neostigmine with Bupivacaine and epidural Bupivacaine u sed alone with regard to onset, duration of analgesia, hemodynamic stability and level of anaesthesia. Patients were divided into two groups of 50 each. Group I received 19ml of 0.5% Bupivacaine+1ml of normal saline. Group II received 19ml of 0.5% Bupivaca ine+100μg of Neostigmine in 1ml of normal saline. In the operating room the patients were assessed for time of onset of analgesia, duration of anaesthesia, level of analgesia and complications. RESULTS : The addition of Neostigmine resulted in significant r apid onset of action, longer duration of analgesia and motor blockade. There was no incidence of respiratory depression, pruritus, fluctuations in blood pressure, or change in pulse rate, except one patient who developed bradycardia. CONCLUSION : Co adminis tration of epidural Neostigmine and Bupivacaine appears to be a useful technique for epidural anaesthesia as it provides faster onset, longer duration of action and haemodynamic stability.

    Full Text Available Objectives. The purpose of this study was to determine the factors associated with whether a woman received an epidural in labor and to determine the main source used to obtain information about labor epidurals. Methods. Over a one-month period, we surveyed all patients who labored, the day after their delivery. We used multiple logistic regression to identify potential predictive factors after initial univariate analysis. Results. 320 women who met enrollment criteria delivered during the study period and 94% completed the study. Of the 302 patients surveyed, 80% received an epidural for labor. Univariate analysis showed the following variables were associated with whether women received an epidural (P<.01: partner preference, prior epidural, language, education, type of insurance, age, duration, and pitocin use. Using computed multiple logistic regression only partner preference and prior epidural were associated with whether women received an epidural. Conclusion. It was not surprising that a previous epidural was predictive of a patient receiving an epidural. The strong association with partner preference and epidural use suggests this is an important factor when counseling pregnant women with regard to their decision to have a labor epidural.

    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.

    Gas-containing (emphysematous) infections of the abdomen, pelvis, and extremities are well-known disease entities, which can potentially be life-threatening. They require aggressive medical and often surgical treatment. In the neurosurgical field, some cases of gas-containing brain abscess and subdural empyema have been reported. Sometimes they progress rapidly and even can cause fatal outcome. However, gas-containing spinal epidural abscess has been rarely reported and clinical course is unknown. We report on a case of rapidly progressive gas-containing lumbar spinal epidural abscess due to Enterococcus faecalis in a 72-year-old male patient with diabetes mellitus.

    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.)

    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 La analgesia epidural se ha convertido en una técnica rutinaria en el manejo perioperatorio de los pacientes quirúrgicos que se ha extendido fuera de los quirófanos y de las unidades de alta dependencia hacia las salas de hospitalización. La irrupción en este nuevo escenario ha mejorado la analgesia postoperatoria con aceptables márgenes de seguridad, lo que le ha servido para colocarse en un lugar predominante entre las pautas analgésicas de las Unidades de Dolor Agudo (UDA. La analgesia epidural con anestésicos locales y opioides frente a la sistémica con opioides ha presentado históricamente una superior eficacia analgésica, y una disminución de complicaciones derivadas de la atenuación del estrés quirúrgico y de la mejora en la función cardiorrespiratoria. Sin embargo, frente a estas ventajas la analgesia epidural también presenta inconvenientes como la hipotensión arterial o la retención urinaria, junto a las potencialmente graves derivadas del daño neurológico ocasionado por un hematoma epidural, una infección o una lesión directa del tejido nervioso. Si sus ventajas han resultado consistentes y fundamentadas, en este momento no lo parecen tanto. El avance que ha supuesto la cirugía mínimamente invasiva con altas más precoces, junto al desarrollo de estrategias multimodales, está conduciendo a un replanteamiento de la utilización de técnicas como la epidural y a una reevaluación de sus indicaciones. Las últimas evidencias nos inducen a pensar que la epidural probablemente haya tocado techo en el tratamiento del dolor postoperatorio y comenzará a perder terreno frente a otras técnicas igualmente efectivas, con menores complicaciones y efectos secundarios. Este será un proceso lento en el que deberá quedar asegurado que las alternativas analgésicas ofrecen realmente mejores resultados en cuanto a eficacia, seguridad, tolerabilidad y calidad de la recuperación desde la perspectiva del paciente.Epidural

La casuística, entretanto, no es aún suficiente para permitir conclusiones definitivas.BACKGROUND AND OBJECTIVES: The cardiotoxic effect of racemic bupivacaine (50:50 is still the major safety-related variable for regional blocks requiring higher concentrations and volumes. Recent animal studies suggested that the manipulation of racemic bupivacaine enantiomers could contribute for a better therapeutic efficacy by decreasing its potential toxicity. This study aimed at evaluating the efficacy of 0.5% bupivacaine enantiomeric mixture (S75-R25 as compared to plain S(-100% bupivacaine in lumbar epidural anesthesia for varicose vein surgery. METHODS: Participated in this randomized double-blind study 30 female patients aged 15 to 65 years, physical status ASA I or II scheduled for elective lower limb varicose vein surgery, who were allocated into two groups: S75-R25 Group - 20 ml (100 mg of 0.5% (S75-R25 bupivacaine; and Levogyrous Group - 20 ml (100 mg of 0.5% plain S(-100 bupivacaine without adjuvants. Characteristics of sensory and motor block as well as the incidence of side effects were investigated. RESULTS: Significant demographic differences and a longer surgical time were found in the S75-R25 Group. Faster spread and lower analgesic effects of the isomeric mixture were statistically significant. Motor block was significantly deeper in the S75-R25 Group. Side effects were negligible for both groups. CONCLUSIONS: Fewer side effects, good patients acceptance and the lack of post-operative transient neurological symptoms point towards the safety of both solutions in lumbar epidural anesthesia for elective varicose vein surgery. The sample, however, is still small for final conclusions.

    To our knowledge, there are no reports in the literature of patients with Parkinson disease (PD) developing upper cervical spine infections. Our objective is to present a case of upper cervical epidural abscess in a patient with PD and to review upper cervical spine infection. We present the patient’s presentation, physical examination, imaging findings, and management as well a review of the literature. A 66-year-old male with PD presented to the emergency department (ED) following referral by a neurologist for a presumed C2 fracture. The preceding history was 1 week of severe neck pain requiring a magnetic resonance imaging (MRI), which was initially interpreted as a C2 fracture. On admission from the ED, further review of the MRI appeared to show anterior prevertebral abscess and an epidural abscess. The patient’s neurological examination was at baseline. In the span of 2 days, the patient developed significant motor weakness. A repeat MRI demonstrated expansion of the epidural collection and spinal cord compression. Surgical management consisting of C1 and C2 laminectomy, irrigation, and debridement from anterior and posterior approaches was performed. Postoperatively, the patient did not recover any motor strength and elected to withdraw care and died. Spinal epidural abscess requires a high index of suspicion and needs prompt recognition to prevent neurological impairment. Upper cervical spine infections are rare but can lead to lethal consequences. PMID:26623170

    Purpose: The spinal epidural angiolipomas are rare expansive processes made of mature lipomatous and angiomatous elements. They often have a benign character. Their etiology, pathogenesis remains uncertain, and it is a cause of spinal cord compression. The magnetic resonance imaging is the most important neuroradiological examination. Histological examination is the only examination to confirm the diagnosis. Surgery is the treatment of choice. Methods: A retrospective study of all patients operated on for a spinal epidural angiolipoma at the Department of Neurosurgery at the National Institute of Neurology of Tunis between January 2000 and December 2014 (15 years) was performed. The aim of this study is to describe the clinical, radiological, histological characteristics and the treatment of this tumor. Results: A total of nine patients were operated from January 01, 2000 to November 30, 2014. The average age of our patients was 51 years with ages that ranged from 29 to 65 with a male predominance. The period between onset of symptoms and diagnosis ranged from 24 months with an average 12 months. Posterior localization of the tumor was seen in all patients. Surgical resection was performed for all cases. The postoperative course has been satisfactory, with a complete recovery of neurological functions in all patients. Conclusions: The spinal epidural angiolipomas is rare expansive process causing spinal cord compression. Treatment is exclusively surgical resection. The functional outcome of spinal epidural angiolipomas is particularly favorable with a complete neurological recovery is if the patient was quickly operated. PMID:27695535

    Properly administered epidural analgesia provides adequate pain relief during labor and delivery, shortens the first stage of labor, avoids adverse effects of narcotics, hypnotics, or inhalation drugs and it could be used as anesthesia in case a cesarean section is required. Epidural analgesia should be provided to all patients who need and ask for it with an exception of contraindications such as coagulation disorders, suspected infection or gross anatomic abnormality. The technique must be carried out with care if serious life-threatening complications, such as intravenous or intrathecal injection of local anesthetic, are to be avoided. The aim of many recent investigations has been to reduce the total dose of local anesthetic used. Supplementation of an opioid (mainly fentanyl) and introduction of the patient controlled epidural pump may not only serve this goal, but also reduce the demands on the time of obstetric anesthetists. We conclude that properly and skillfully administered epidural is the best form of pain relief during labor and delivery and we hope that more mothers could enjoy its benefits.

    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)

    Full Text Available Background and Objectives. Previous studies have used varying methods to estimate the depth of the epidural space prior to placement of an epidural catheter. We aim to use computed tomography scans, patient demographics, and vertebral level to estimate the depth of the loss of resistance for placement of thoracic epidural catheters. Methods. The records of consecutive patients who received a thoracic epidural catheter were reviewed. Patient demographics, epidural placement site, and technique were collected. Preoperative computed tomography scans were reviewed to measure the skin to epidural space distance. Linear regression was used for a multivariate analysis. Results. The records of 218 patients were reviewed. The mean loss of resistance measurement was significantly larger than the mean computed tomography epidural space depth measurement by 0.79 cm (p<0.001. Our final multivariate model, adjusted for demographic and epidural technique, showed a positive correlation between the loss of resistance and the computed tomography epidural space depth measurement (R2=0.5692, p<0.0001. Conclusions. The measured loss of resistance is positively correlated with the computed tomography epidural space depth measurement and patient demographics. For patients undergoing thoracic or abdominal surgery, estimating the loss of resistance can be a valuable tool.

    To (a) evaluate the feasibility of MR epidurography (MRE) and (b) assess the distribution of injectate using two different volumes at caudal epidural steroid injection. Twenty patients who were referred with symptomatic low back pain for caudal epidural steroid injection were assigned to have either 10 ml (9/20) or 20 ml (11/20) of injectate administered. Gadolinium was included in the injection. The patients proceeded to MRI where sagittal and coronal T1-weighted fat-saturated sequences were acquired and reviewed in the mid-sagittal and right and left parasagittal views at the level of the exit foramina. Gadolinium was observed at or above the L3/4 disc level in all 11 patients who received 20 ml (100 %), compared with only five of nine patients who received 10 ml (56 %). Injectate was seen to the L4 nerve root level in all 11 patients who received 20 ml (100 %) but only four out of nine patients who received 10 ml (44 %), not even reaching the L5 nerve root level in four further of these nine patients (44 %). Overall, there was a trend to visualize gadolinium at higher levels of the epidural space with higher volumes injected. Firstly, MR epidurography is a safe technique that allows excellent visualization of the distribution of gadolinium in the epidural space following injection via the caudal hiatus. Secondly, a volume of 10 ml is unlikely to treat L5/S1 disease in almost half of patients at caudal epidural steroid injection and at least 20 ml of injectate is likely required for any medication to reach the desired level.

    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.

We report the case of a 67-year old man who presented to the Accident and Emergency department complaining of acute onset of inter-scapular back pain, left leg weakness and loss of sensation in the left foot. On examination he was found to be pyrexial with long tract signs in the left lower leg. In addition he had a left sided olecranon bursitis of three weeks duration. Blood tests revealed raised inflammatory markers and a staphylococcal bacteremia. Magnetic resonance imaging (MRI) confirmed the diagnosis of spinal epidural abscess and he subsequently underwent a three level laminectomy with good resolution of his back pain and neurological symptoms. He has made a complete recovery with a prolonged course of intravenous antibiotics.

    Epidural blood patch (EBP) is the currently accepted treatment of choice for postdural puncture headache because of its high initial success rates and infrequent complications. Many authors recommended a small volume (10-20 mL) of blood to be delivered for an effective EBP. Here, we report an obstetric patient who developed a transient bladder and fecal incontinence after 19 mL of blood EBP at L1 -L2 level. Since the magnetic resonance image did not demonstrate any definitive spinal cord lesion, the exact mechanism remains unclear. We suggest that accumulation of blood performed at L1 to L2 level in a closed relationship with the sacral cord, may have trigger a significant pressure elevation of the epidural space at this level, resulting in a temporal spinal cord-related injury in the sacral cord.

    Spontaneous spinal epidural hematoma (SSEH) is a rare but real neurosurgical emergency. It is caused by atraumatic rupture of the vertebral epidural vein that results in nerve root or spinal cord compression. Most cases of SSEH have a multifactorial etiology, including congenital and acquired coagulopathies; platelet dysfunction; vascular malformation; tumors; uncontrolled hypertension; pregnancy; and, very rarely, activities requiring Valsalva. Herein we reported the case of a young pianist who was attacked by SSEH during piano practice. Playing the piano is a joyful, relaxing entertainment; however, this musical activity can be a highly demanding physical and mental exercise for pianists. Emotional and expressive performance, especially in professional performing, has been reported to result in significant increase of sympathetic and decrease of parasympathetic activities and thus influence the cardiorespiratory variables. The increased biomechanical stress from fluctuating hemodynamics was thought to trigger the rupture of her spinal arteriovenous malformation.

    Full Text Available Las formas corrientes de resistencia entre los campesinos incluyen el disimulo, la lentitud en el ejercicio de sus tareas, el fingimiento de ignorancia, el hurto de pequeñas cosas y el sabotaje. Otras formas de acción campesina comprende los desafíos a la usurpación de sus asentamientos por empresarios de tierras. A través de estas formas de resistencia los campesinos prepararon el escenario para el desarrollo de la conciencia de clase campesina en épocas posteriores. La historiografía colombiana ha subestimado la importancia de los campesinos en el Siglo XLX en la región Central colombiana debido posiblemente al reducido número de revueltas rurales, hecho que contrasta con la atención que se ha puesto en el estudio de los levantamientos campesinos del siglo XX.

    Spinal epidural abscess (SEA) is an uncommon condition and its most important predisposing factor is diabetes mellitus. Although the treatment of choice is prompt surgical abscess evacuation, followed by antibiotic therapy, successful conservative treatment of SEA has been reported in some cases. We describe a SEA case in a 23-year old white woman with diabetes for 14 years, who was successfully treated only with antibiotics, and achieved full recovery at the fourth month of follow-up.

    Hands-and-knees position has shown promise as an intervention to improve labor and birth outcomes, but no reports exist that examine its use with women laboring with epidural analgesia. Concerns of safety, effects on analgesia, and acceptability of use may limit use of active positioning during labor with regional analgesia. This article presents a case study series of 13 women who used hands-and-knees position in the first stage of labor.

Our case first developed acute and had progressive cervical spinal cord signs that determined emergency decompressive laminectomy. On the other hand, the second patient, who was chronic, was operated almost five months after the initial symptoms and the radiological diagnosis was a large facet cyst. Early surgical intervention is the chosen treatment for spontaneous spinal epidural hematomas. Spinal surgeons should bear in mind that spontaneous spinal epidural hematomas may have different clinical presentations according to their location in order to perform a differential diagnosis.Fueron relatados dos casos de hematoma epidural espinal espontáneo con diferentes presentaciones clínicas sin factores precipitantes, y fue hecha una breve revisión de la literatura.

    A 56-year-old man presented with a rare spinal epidural abscess manifesting as attacks of back pain associated with fever, weight loss, generalized weakness and fatigability, and constipation. He had multiple skin pustules in the last 4 months treated with oral amoxicillin. He had suffered diabetes mellitus for the last 5 years and was insulin dependent. Physical examination found slight paraparesis with sensory loss around the nipple and sphincteric urgency, and diabetic retinopathy. Magnetic resonance imaging showed edematous T2, T3, and T4 vertebral bodies, and narrow enhanced T3-4 disk space with a soft tissue enhanced mass mostly anterior to the spinal cord and indenting the cord. T3-4 costotransversectomy was performed to remove the extradural mass and evacuate the intradiscal material. Histological examination of the bone found osteomyelitis, and culture of the soft tissue showed Salmonella typhi sensitive to ceftriaxone and ciprofloxacin. Intravenous ceftriaxone administration was started, and the patient was discharged after 6 days in good condition. The outcome of spinal epidural abscess is devastating unless recognized and treated early. The present case of spinal epidural abscess in the thoracic spine caused by Salmonella typhi infection illustrates the importance of cultures to assess the drug sensitivity of the specific strain detected and adjusting the treatment accordingly.

    Full Text Available Introduction: Anatomy of the sacral hiatus is having clinical importance during caudal epidural block. Present study is aimed at determining anatomy of sacrum specially sacral hiatus for caudal epidural block, with the help of morphometric measurements of the sacrum in relation to sacral hiatus in dry sacral bones. Material & method: Total 103 complete and undamaged adult, dry sacral bones were measured with Vernier caliper (accuracy 0.1 mm and anatomical measurements were obtained. Results: Three bones were excluded because of total posterior closure defect. Agenesis of the sacral hiatus was detected in three sacral bones. Right and left superolateral sacral crests of the sacrum were taken as two points on dorsal surface of sacrum (forming the base of a triangle because posterior superior iliac spines impose on the superolateral sacral crests. The distance between the two superolateral sacral crests (base of a triangle, the distances between the right and left superolateral sacral crest and the sacral apex were on average 60.61(SD 6.71, 61.95 (11.71 and 61.4 (11.98 mm respectively.. Summary: An equilateral triangle formed between the apex of the sacral hiatus and right and left superolateral sacral crests. This equilateral triangle will help in determining the location of the sacral hiatus during caudal epidural block. [National J of Med Res 2012; 2(3.000: 272-275

    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.

    Buprenorphine plasma concentrations were measured after administering buprenorphine (20 μg/kg) into the lumbosacral epidural space of conscious cats chronically instrumented with an epidural catheter. Blood was collected from a jugular vein before injection and 15, 30, 45 and 60 min and 2, 3, 4, 5, 6, 8, 12 and 24 h after administration. Plasma buprenorphine concentrations were measured using ELISA. Background concentration (before injection) was 1.27 ± 0.27 ng/mL (mean ± SD). Including background concentration, the mean peak plasma concentration was obtained 15 min after injection (5.82 ± 3.75 ng/mL), and ranged from 3.79 to 2.20 ng/mL (30 min-3 h), remaining between 1.93 and 1.77 ng/mL (4-12 h), and declined to 1.40 ± 0.62 ng/mL at 24h. Elimination half-life was 58.8 ± 40.2 min and clearance 56.7 ± 21.5 mL/min. Results indicate early rapid systemic uptake of buprenorphine from epidural administration with plasma concentrations similar to using buccal or IM routes by 15 min postinjection.

    Full Text Available Background: Epidural anesthesia is regional anesthesia that blocks pain in a particular region of the body. This produces pain relief with minimal side effects. These medications may be used in combination with epinephrine, fentanyl, morphine, or clonidine to prolong the epidural’s effect or to stabilize the mother’s blood pressure. Objectives: This study was conducted to assess the fetomaternal outcome of epidural analgesia in labour. Methods: This study was descriptive case series study which was conducted in department of obstetrics and gynecology, GMERS medical college, Gandhinagar, Gujarat from January 2012 to December 2012. Pregnant women who received epidural analgesia during labour were involved in the study. The inclusion criteria were primi gravida patients who had gestational age of greater than 37 weeks (confirmed by ultrasound without any risk factors, in true labour (cervical dilatation >3 cm with regular uterine contraction and with vertex presentation. Results: Total number of patients was 80 with the mean age of 21.9±1.7 years. Mode of delivery was spontaneous vaginal in 46 patients (57.5%, forceps delivery in 4 patients (5%, ventouse in 14 patients (17.5% and caesarean section in 16 patients (20%.

    Objective To investigate the pharmacokinetics of different concentrations of levobupivacaine for lumbar epidural anesthesia.Methods Twenty ASA Ⅰ or Ⅱ patients of both sexes, aged 35-59 years and scheduled for elective radical resection of rectal or colon carcinoma under general anesthesia combined with epidural block, were randomly divided into 2 groups (n=10 each):group Ⅰ (receiving 0.75% levobupivacaine) and group Ⅱ (receiving 0.5% levobupivacaine). Epidural block was performed at L1-2 interspace. Group Ⅰ and Ⅱ received epidural 0.75% and 0.5% levobupivacaine 2 mg/kg (containing adrenaline 5 μg/kg)injected slowly over 2 min, respectively. And 30 min later, general anesthesia was induced with y-hydroxybutyrate 60-80 mg/kg and remifentanil 1-2μg/kg. Tracheal intubation was facilitated with succinylcholine 1-1.5 mg/kg and the patients were mechanically ventilated. Anesthesia was maintained with inhalation of nitrous oxide (N2 O) and O2 (1:1) and continuous infusion of remifentanil 0.01-0.1μg·kg-1·min-1 and intermittent intravenous boluses of atracurium. Sensory and motor blocks were assessed after epidural levobupivacaine. Blood samples were taken from the central vein at 0, 10, 20, 30, 45, 60, 90, 120, 210, 300, 420,540, 660 and 840 min, respectively, after epidural administration for determination of plasma concentrations of levobupivacaine by high performance liquid chromatography.Results The plasma concentration-time curves of levobupivacaine were fitted to a two-compartment open model in the two groups and there were no significant differences in the pharmacokinetic profiles between the two groups. The onset time of sensory and motor blocks was shorter and the duration of the two blocks was longer with 0.75% levobupivacaine as compared with 0.5%levobupivacaine.

Consequently, the financial benefit due to the MW generated along a period of 2 months, is equivalent to return the investment required if the CCPP would had been repowered. Test also showed that with the fuzzy based SGC is possible to get a 'little more' power generation than if we use the PID based SGC. The development and implementation of the SGC was made in three phases: First Phase: Upgrading of the simulation dynamic mathematical model and implementation in a new software platform based on LabWindows/CVI. Second Phase: Design, implementation and testing of the PID based SGC. Third Phase: Design and implementation and testing of the Intelligent SGC, based in fuzzy logic.

    Summary Background Cavernous malformations are characterized by enlarged vascular structures located in benign neural tissues within the cerebellum and spinal cord of the central nervous system. Cavernous hemangiomas (CHs) account for 5% to 12% of all spinal vascular malformations. Case Report We removed a hemorrhagic thoracic mass in a 40-year-old male patient who presented with progressive neurological deficits. Conclusions We found it appropriate to present this case due to its rarity. PMID:25960818

    Full Text Available JUSTIFICATIVA E OBJETIVOS: A anestesia peridural torácica é utilizada com freqüência para procedimentos estéticos da mama e há poucos relatos de seu emprego para mastectomias com exploração axilar. O presente estudo comparou a técnica com anestesia geral em operações oncológicas da mama. MÉTODO: Quarenta pacientes foram divididas em dois grupos. No grupo peridural (n = 20 foi realizada peridural torácica com bupivacaína e fentanil associada à sedação com midazolam. O outro grupo (n = 20 recebeu anestesia geral convencional com propofol, atracúrio e fentanil e manutenção com O2 e isoflurano. Registraram-se no intra-operatório duração da operação, necessidade de complementação da anestesia ou da sedação e variáveis hemodinâmicas. No pós-operatório, foram registrados o tempo para alta da sala de recuperação pós-anestésica e hospitalar, a intensidade da dor e o consumo de analgésicos, os efeitos adversos e a satisfação com a técnica anestésica. RESULTADOS: Os grupos foram semelhantes e não houve diferença na duração da operação. Foi necessário complementar a sedação em 100% das pacientes que receberam anestesia peridural e em 15% foi complementada a analgesia com infiltração de anestésico local na axila. Houve maior incidência de hipertensão arterial no grupo da anestesia geral e de hipotensão entre as que receberam peridural. Ocorreu prurido em 55% das pacientes com anestesia peridural. Náusea (30% e vômito (45% foram mais freqüentes entre as que receberam anestesia geral. A analgesia pós-operatória teve melhor qualidade e o consumo de analgésicos foi menor no grupo da anestesia peridural. O período de internação também foi menor. CONCLUSÕES: A técnica peridural tem algumas vantagens com relação à anestesia geral e pode ser considerada uma opção para anestesia em mastectomias oncológicas com esvaziamento axilar.JUSTIFICATIVA Y OBJETIVOS: La anestesia epidural torácica se

    There are no reports regarding pneumomediastinum caused by thoracic epidural block complications. We believe that it is possible to experience an occurrence of pneumomediastinum caused by air in the epidural space after performing a thoracic epidural block using the loss of resistance (LOR) technique with air. We report a witnessed case where pneumomediastinum appeared after a thoracic epidural block. Pneumorrrhachis, paravertebral muscle emphysema, and pneumomediastinum were diagnosed by Positron Emission Tomography-Computed Tomography. Although extremely rare, pneumomediastinum can be caused by an epidural block using LOR technique with air. In order to avoid the above danger, the use of saline or very minimal amount of air is required during a careful LOR technique.

    The effects and side effects of thoracic epidural analgesia on the respiratory response, awakening time, and cooperation with nurses were studied. Forty children received epidural analgesia after open-heart surgery. Lidocaine was injected in a dose of 1.5-2 mg/kg every 1.5-2 h. Controls (16 pts) received intravenous fentanyl + diazepam analgesia. Respiratory response and awakening were significantly earlier (p < 0.001) in the epidural group. Cooperation with nurses was much better in this group, too. No side effects were observed in the epidural group. Therefore, thoracic epidural analgesia is a safe and effective method of postoperative analgesia for children subjected to open-heart surgery.

    Full Text Available The objective of this work was to identify key locations for the establishment of soybean (Glycine max genetic breeding programs, in the Central Region of Brazil. Grain yield data of three maturity groups of soybean genotypes, from regional trials conducted over three years, at 18 locations in Brazilian Cerrado were used. A key location for the early phases of the breeding program was defined as the site that best classifies the winning genotypes in the region. Key locations for the final phases were defined as those sites that best represent each environmental stratum, in relation to the adaptability of the respective winning genotype. This adaptability was estimated by additive main effects and multiplicative interaction (AMMI model analysis, using the distance between the score of each location in a stratum and the score of the winning genotype, which characterizes such stratum in an AMMI biplot. The locations that best classified the winning genotypes over space and time were Mineiros, Placas and Rio Verde. For the final phases of genotype selection, with data from the three maturity group, the recommended locations were: Buritis, Chapadão do Céu, Iraí, Pamplona, Placas, Planaltina, Rio Verde, Sacramento, Senador Canedo, Uberaba, and Uberlândia.O objetivo deste trabalho foi identificar locais-chave para o estabelecimento de programas de melhoramento genético de soja (Glycine max, na Região Central do Brasil.

  2. Epidural analgesia practices for labour: results of a 2005 national survey in Ireland.

    LENUS (Irish Health Repository)

    Fanning, Rebecca A

    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.

    Full Text Available OBJECTIVES: To identify risk factors for short-term percutaneously inserted central venous catheter-related infections in children and to evaluate the accuracy of a mortality score in predicting the risk of infection. METHOD: After reviewing the charts of patients who developed catheter-related infection in a university hospital's pediatric intensive care unit, we conducted a case-controlled study with 51 pairs. Variables related to patients and to catheter insertion and use were analyzed. Risk factors were defined by logistic regression analysis. The accuracy of the Pediatric Risk of Mortality score to discriminate the risk for infection was tested using the Receiver Operating Characteristic curve. RESULTS: Infection was associated with respiratory failure, patient's length of stay, duration of tracheal intubation, insertion of catheter in the intensive care unit and parenteral nutrition. Insertion site (femoral or internal jugular was unimportant. Multivariate logistic regression analysis identified the following variables. Risk factors included more than one catheter placement (p=0.014 and duration of catheter use (p=0.0013, and protective factors included concomitant antibiotic use (p=0.0005 and an intermittent infusion regimen followed by heparin filling compared to continuous infusion without heparin (p=0.0002. Pediatric Risk of Mortality did not discriminate the risk of infection. CONCLUSIONS: Central parenteral nutrition and central venous catheters should be withdrawn as soon as possible. Femoral vein catheterization carries a risk of infection similar to internal jugular catheterization. The Pediatric Risk of Mortality score should not be used to predict the risk of central catheter-related infections.OBJETIVOS: Identificar fatores de risco para as infecções relacionadas a cateter venoso central de curta permanência, inserido por punção, em crianças e avaliar a eficiência de um escore de mortalidade pediátrica em prever o risco

    Intrapartum fever is associated with excessive maternal interventions as well as higher neonatal morbidity. Epidural-related maternal fever (ERMF) contributes to the development of intrapartum fever. The mechanism(s) for ERMF has remained elusive. Here, we consider how inflammatory mechanisms may be modulated by local anesthetic agents and their relevance to ERMF. We also critically reappraise the clinical data with regard to emerging concepts that explain how anesthetic drug-induced metabolic dysfunction, with or without activation of the inflammasome, might trigger the release of nonpathogenic, inflammatory molecules (danger-associated molecular patterns) likely to underlie ERMF.

    Formulation and validation of a dispersion model for relative plumes are presented in this paper. This model (MOTTQUIP: Modelo de Transporte Turbulento y Quimico de Plumas) was developed to assess the environmental impact of power generation. The theoretical formulation if this model is based on the integral form of the mass balance equation. MOTTQUIP can simulate (in two dimensions) the turbulent dispersion and chemical transformation phenomena of a nitrogen oxides (Nox) non-buoyant plume in an ozone (O{sub 3}) atmosphere. The results produced by MOTTQUIP, however, can run in a personal computer consuming relatively short CPU times. [Spanish] En este trabajo se presentan la formulacion y la validacion de un modelo (MOTTQUIP: Modelo de Transporte Turbulento y Quimica de Plumas) para evaluar el impacto de las emisiones de contaminantes reactivos de centrales termoelectricas. Este modelo se formula a partir de la forma integral de la ecuacion de balance de masa, y no de su forma diferencial, como se procede generalmente. MOTTQUIP simula, en dos dimensiones, la dispersion turbulenta y transformacion quimica de una pluma no flotante de oxidos de nitrogeno (Nox), misma que se interna paulatinamente en un ambiente de ozono (O{sub 3}). Los resultados obtenidos son comparados con los de modelos alternos que simulan el mismo sistema reactivo, encontrandose una concordancia bastante aceptable. Una ventaja de MOTTQUIP, sin embargo, es que puede utilizarse en sistemas de computo pequenos, empleando tiempos de CPU relativamente cortos.

    A retrospective review was done on medical records of 13 patients with persistent post-dural-puncture headaches after one or more epidural blood patches. Headache occurred in nine patients with post-laminectomy syndrome after "wet taps" while performing epidural blocks. In two patients post-dural-puncture headache appeared after long term implanted intrathecal catheters were removed. In two other cases headache developed after spinal anesthesia. Treatment included bed rest, intravenous hydration and at least one epidural blood patch; three patients were given 60 milliliters of epidural saline, without success. Eight epidural catheters were inserted through the lumbar access and five through the caudal approach. Initially, a bolus of 20 milliliters of dextran-40 was given followed by an infusion of 3 mL/hr, until 12 hours after the head pain and any other related symptoms subsided. In all patients the headache disappeared within 20 hours after initiating therapy (9.55 mean hours, SD +/- 0.79). In five patients headache ceased in less than five hours. Nausea and photo-phobia subsided earlier. Patients with post-dural-puncture headache resistant to other treatments, including at least one epidural blood patch, were successfully treated by a bolus followed by continuous epidural infusion of dextran-40.

    Spinal epidural abscess (SEA) is a rare but often devastating infection of the epidural space around the spinal cord. When an SEA is widespread, extensive decompression with laminectomy is often impossible, as it may subject the patient to very long operative times, extensive blood loss, and mechanical instability. A technique called "skip laminectomy" has been described in the literature, in which laminectomies are performed at the rostral and caudal ends of an abscess that spans 3-5 levels and a Fogarty catheter is used to mechanically drain the abscess, much like in an embolectomy. In this report of 2 patients, the authors present a modification of this technique, which they call "apical laminectomies" to allow for irrigation and drainage of an extensive SEA spanning the entire length of the vertebral column (C1-2 to L5-S1). Two patients presented with cervico-thoraco-lumbar SEA. Laminectomies were performed at the natural apices of the spine, namely, at the midcervical, midthoracic, and midlumbar spine levels. Next, a pediatric feeding tube was inserted in the epidural space from the thoracic laminectomies up toward the cervical laminectomy site and down toward the lumbar laminectomy site, and saline antibiotics were used to irrigate the SEA. Both patients underwent this procedure with no adverse effects. Their SEAs resolved both clinically and radiologically. Neither patient suffered from mechanical instability at 1 year after treatment. For patients who present with extensive SEAs, apical laminectomies seem to allow for surgical cure of the infectious burden and do not subject the patient to extended operating room time, an increased risk of blood loss, and the risk of mechanical instability.

    OBJECTIVE There is little information on the frequency of symptomatic epidural hematomas after the implantation of paddle spinal cord stimulators (SCSs) in the thoracic spine. The purpose of this paper is to provide this metric and compare it to the frequency of symptomatic epidural hematomas for all other thoracic laminectomies combined. METHODS This study involved retrospectively analyzing the experience of a single surgeon in a consecutive series of patients who underwent the implantation of a thoracic paddle SCS with respect to the occurrence of a symptomatic epidural hematoma. For comparison, the occurrence of a symptomatic epidural hematoma in non-SCS thoracic laminectomies done during the same period of time was determined. RESULTS One hundred fifty-four thoracic paddle SCSs were implanted between May 2002 and February 2015. Despite perfect hemostasis and no preoperative risk factors, 4 of 154 patients (2.60%) developed postoperative lower-extremity weakness caused by an epidural hematoma. There were no other causes of a neurological deficit. In 3 of the 4 patients, the symptoms were delayed. Over the same time period, only 1 of 119 patients (0.84%) developed a postoperative motor deficit from a symptomatic epidural hematoma after a non-SCS laminectomy. CONCLUSIONS The occurrence of epidural hematomas after thoracic paddle SCS implantation may be underreported. Suggestions are given to decrease its incidence. It seems paradoxical that an epidural hematoma occurred 3 times more often after small SCS thoracic laminectomies than after larger non-SCS thoracic laminectomies. If confirmed by future studies, this finding may suggest that the intrusion of instruments into a confined epidural sublaminar space or the presence of a paddle and a hematoma in this restricted space may account for this differential.

    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.

    Full Text Available ABSTRACT Univariate and multivariate statistical analyses of 28 meristic characters recorded for 19 samples of the lizard Liolaemus monticola monticola were used to compare geographical variation in morphology with chromosomal races north and south of the Maipo River, and north and south of the Aconcagua River in central Chile, plus some affluent. This extends a previous morphological study that confirmed that the Maipo River is a biogeographical barrier that separates chromosomal races "Southern, 2n=34" and "Northern, 2n=38-40", and reports for the first time the importance of the Aconcagua River as another biogeographical barrier between the chromosomal races "Northern, 2n=38-40" and the "Multiple Fission, 2n=42-44". The phenetic variation among samples is sufficient to differentiate the three chromosomal races, and also distinguishes populations within the chromosomal races such as the ones separated by the Colorado River, an affluent of the Aconcagua River. A possible historical sequence of events that accounts for the pattern of morphological differentiation is advanced.Se emplearon análisis estadísticos univariados y multivariados de 28 caracteres merísticos de 19 poblaciones de Liolaemus monticola monticola para comparar la variación geográfica morfológica en las razas cromosómicas, tanto al sur y norte del río Maipo, como al sur y norte del río Aconcagua, más algunos afluentes.

    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.)

    Spontaneous epidural abscess formation is a rare finding in all populations and even more so in the pediatric population. Its rarity and varied presentations often lead to misdiagnosis. We present a pediatric case in which the diagnosis of spontaneous spinal epidural abscess was missed upon initial presentation and subsequently identified at a later visit to the emergency department. Literature suggests utilizing three simple physical exam findings that may improve the first visit diagnosis of spontaneous epidural abscesses in children. Findings of any two of the following signs should guide the clinician to consider SEA as a possibility prior to discharge: fever, back or neck pain, extremity weakness or inability to walk.

    Full Text Available We report a case of temporomandibular joint dislocation occurring in the postoperative period in a patient, who developed catatonia following administration of a single dose of epidural morphine. The catatonic response to epidural morphine was delayed by several hours in the postoperative period, and might have resulted from intrathecal migration of the drug, through an initial dural puncture while locating the epidural space. The temporomandibular joint dislocation was diagnosed only after reversal of the effects of morphine with naloxone, when the patient complained of inability to fully close her mouth.

  1. Anaphylaxis at image-guided epidural pain block secondary to corticosteroid compound.

    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.

    Epidural hematoma is a rare cause of spinal cord compression, which usually provokes severe neurological deficits. It is presumed to originate from venous or, more probably, arterial bleeding. Thrombocytopenia and other disorders of coagulation may precipitate the onset of epidural hematoma and facilitate the evolution of the disease. We report the case of a patient suffering from a non-Hodgkin's lymphoma with severe thrombocytopenia during a MACOP-B schedule, who presented with a spontaneous cervical epidural hematoma. We discuss the etiopathological aspects, diagnosis, and treatment of this rare cause of acute cervical spinal cord compression.

    Full Text Available Epidural steroid injections are well accepted as a treatment for radicular back pain in appropriate candidates. While overall incidence of systemic side effects has not been well established, at least five biochemically proven cases of iatrogenic Cushing's Syndrome have been reported as complications of epidural steroid treatment. We present an additional case of iatrogenic Cushing's Syndrome and adrenal suppression in a middle-aged woman who received three epidural steroid injections over a four-month period. We review this case in the context of previous cases and discuss diagnostic and management issues.

    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.

    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.

    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.

    Aortic coarctation complicated with spinal artery aneurysm rupture is exceptionally rare and can be source of intraspinal hemorrhage with markedly poor prognosis. A 21-year-old man visited the emergency department because of chest and back pain along with immobility of bilateral lower limbs immediately after he woke up in the morning. Complete flaccid paraplegia and hypoesthesia in dermatome below bilateral T3 level and pain over axial region from neck to lumbar region were noted. A computed tomography excluded aortic dissection. Magnetic resonance imaging revealed a fusiform lesion involving the anterior epidural space from C7 to T2 level suspected of epidural hemorrhage, causing compression of spinal cord. He started intravenous corticosteroid but refused operation concerning the surgical benefits. Severe chest pain occurred with newly onset right bundle branch block that developed the other day. Coronary artery angiography revealed myocardial bridge of left anterior descending coronary artery at middle third and coarctation of aorta. He underwent thoracic endovascular aortic repair uneventfully. The patient was hemodynamically stable but with slow improvement in neurologic recovery of lower limbs. Aortic coarcation can cause paralysis by ruptured vascular aneurysms with spinal hemorrhage and chest pain that mimics acute aortic dissection. A history of hypertension at young age and aortic regurgitated murmurs may serve as clues for further diagnostic studies. Cautious and prudent evaluation and cross disciplines cares are essential for diagnosis and successful management of the disease.

    Epidural electrostimulation has shown promise for spinal cord injury therapy. However, finding effective stimuli on the multi-electrode stimulating arrays employed requires a laborious manual search of a vast space for each patient. Widespread clinical application of these techniques would be greatly facilitated by an autonomous, algorithmic system which choses stimuli to simultaneously deliver effective therapy and explore this space. We propose a method based on GP-BUCB, a Gaussian process bandit algorithm. In n = 4 spinally transected rats, we implant epidural electrode arrays and examine the algorithm's performance in selecting bipolar stimuli to elicit specified muscle responses. These responses are compared with temporally interleaved intra-animal stimulus selections by a human expert. GP-BUCB successfully controlled the spinal electrostimulation preparation in 37 testing sessions, selecting 670 stimuli. These sessions included sustained autonomous operations (ten-session duration). Delivered performance with respect to the specified metric was as good as or better than that of the human expert. Despite receiving no information as to anatomically likely locations of effective stimuli, GP-BUCB also consistently discovered such a pattern. Further, GP-BUCB was able to extrapolate from previous sessions' results to make predictions about performance in new testing sessions, while remaining sufficiently flexible to capture temporal variability. These results provide validation for applying automated stimulus selection methods to the problem of spinal cord injury therapy.

  11. Laparoscopic hernioplasty with epidural anesthesia; a report of 20 patients

    Full Text Available Background: The incidence of inguinal hernia is 15 cases per 1,000 populations. The most common surgical methods of hernia repair are conventional open hernioplasty and laparoscopic hernioplasty. The advantages of laparoscopic hernioplasty are that the regional anatomy is observable, and bilateral herniorrhaphy can be performed at the same time. Since laparoscopic hernia is usually performed under general anesthesia, to shorten the length of hospital stay and to prevent complications, in this study, we evaluated the use of epidural anesthesia during hernioplasty. Methods: This study included 20 male patients treated by a single surgeon. We recorded the PCO2 levels before, during and after surgery, as well as the pain and intra-abdominal pressure. Results: Only one patient required conversion to general anesthesia. Three patients had hernia on the left side only, 14 patients on the right only and three patients had bilateral hernia. The PCO2 levels did not change (P=0.789. Fifty percent of patients had no postoperative pain. The median time to return to work or normal physical activity was 7 days. Conclusion: Laparoscopic inguinal herniorrhaphy is a feasible alternative to open surgical hernia repair. Employing epidural anesthesia prevents the complications of general anesthesia. This method achieves a shorter hospital stay and time to return to normal activity, as well as reduction in pain. Controlled trials comparing laparoscopic and tension-free open herniorrhaphy are needed to further assess the relative benefits of this procedure.

    2014-11-01

    Full Text Available BACKGROUND: Epidural anaesthesia is used extensively for both intra-operative and post-operative analgesia. This prospective randomized study was conducted using opioids epidurally for post-operative analgesia. Fentanyl is a pure opioid agonist. Butorphanol tartarate which is an agonist antagonist opioid is considered safer than pure opioid agonist. Hence, we compared epidural 4mg butorphanol and epidural 100 µg fentanyl for the relief of post-operative pain. AIMS AND OBJECTIVES: To compare the onset, duration, quality of analgesia, hemodynamic effects and side effects between the 2 study drugs. MATERIALS AND METHODS: 60 patients of either sex posted for elective lower abdominal and lower limb surgeries were randomly divided into 2 groups of 30 each. Group A received butorphanol 4mg epidurally. Group B received fentanyl 100 µg epidurally. All surgeries were done under lumbar epidural anaesthesia with catheter in situ. Post-operatively when patients complained of pain, intensity of pain was assessed using visual analogue scale [VAS]. When the VAS score was > 5, Group A received butorphanol 4mg diluted to 10 ml with NS or Group B received 100 µg fentanyl epidurally diluted to 10 ml with NS. Onset, duration, quality of analgesia, hemodynamic effects and incidence of side effects were compared between the two groups and treated accordingly. RESULTS: Demographic profile was comparable in both groups. Mean time of onset of analgesia was rapid (3.22 ±0.9 (S.D min in group B compared to group A (6.38± 1.26 (S.D min. Duration of analgesia was longer in group A (344.00 ±63.39 min compared to group B (227±38.12 min. Quality of analgesia was better with group A compared to group B. There was no significant difference in hemodynamic parameters in both groups. Sedation was the main side effect in group A. Incidence of pruritis, vomiting, hypotension and respiratory depression was more in group B. CONCLUSION: Epidural Butorphanol though has a delayed

    Full Text Available Background: Epidural steroid injections (ESI in the lumbar spine are not effective over the long-term for resolving "surgical" lesions. Here, we present a patient with a massive L2-L3 lumbar disk herniation whose surgery was delayed for 4 months by multiple unnecessary ESI, resulting in a cauda equina syndrome. Methods: A 54-year-old male acutely developed increased low back and radiating left leg pain in October of 2014. In December of 2014, a magnetic resonance imaging (MRI scan showed a massive central/left sided disk herniation at the L2-L3 level resulting in marked thecal sac and left L2 foraminal and L3 lateral recess root compression. Despite the marked degree of neural compression, pain management treated him with 3 ESI over the next 3 months. Results: At the end of April of 2015, he presented to spine surgeon with a cauda equina syndrome. When the new MRI scan confirmed the previously documented massive central-left sided L2-L3 disk herniation, the patient emergently underwent an L1-L3 laminectomy with central-left sided L2-L3 lateral/foraminal diskectomy. Postoperatively, the patient was neurologically intact. Conclusions: Pain specialists performed multiple unnecessary lumbar ESI critically delaying spinal surgery for 4 months in this patient with a massive lumbar disk herniation who ultimately developed a cauda equina syndrome. Unfortunately, pain specialists (e.g., radiologists, anesthesiologists, and physiatrists, not specifically trained to perform neurological examinations or spinal surgery, are increasingly mismanaging spinal disease with ESI/variants. It is time for spine surgeons to speak out against this, and "take back" the care of patients with spinal surgical disease.

    The purpose of this study was to evaluate the diagnostic value of a spreading epidural hematoma (SEH) and deep subcutaneous edema (DSE) as indirect signs of posterior ligamentous complex (PLC) injuries on MR imaging of thoracolumbar burst fractures. We retrospectively reviewed spinal MR images of 43 patients with thoracolumbar burst fractures: 17 patients with PLC injuries (study group) and 26 without PLC injuries (control group). An SEH was defined as a hemorrhagic infiltration into the anterior or posterior epidural space that spread along more than three vertebrae including the level of the fracture. A DSE was regarded as a fluid-like signal lesion in the deep subcutaneous layer of the back, and its epicenter was at the burst fracture level. The frequency of the SEH/DSE in the two groups was analyzed. In addition, the association between each sign and the degree of vertebral collapse, the severity of central canal compromise, and surgical decisions were analyzed. Magnetic resonance images showed an SEH in 20 out of 43 patients (46%) and a DSE in 17 (40%). The SEH and DSE were more commonly seen in the study group with PLC injuries (SEH, 15 out of 17 patients, 80%; DSE, 16 out of 17 patients, 94%) than in the control group without PLC injuries (SEH, 5 out of 26, 19%; DSE, 1 out of 26, 4%) (P <0.0001). The SEH and DSE were significantly associated with surgical management decisions (17 out of 20 patients with SEH, 85%, vs 8 out of the 23 without SEH, 35%, P =0.002; 15 out of 17 with DSE, 88%, vs 10 out of 26 without DSE, 38%, P =0.002). The SEH and DSE did not correlate with the degree of vertebral collapse or the severity of central canal compromise. The SEH and DSE may be useful secondary MR signs of posterior ligamentous complex injury in thoracolumbar burst fractures. (orig.)

    Background Despite low morbidity, acute or subacute spinal epidural hematoma may develop quickly with a high tendency to paralysis. The delay of diagnosis and therapy often leads to serious consequences. In this study we evaluated the effects of a series of methods for the diagnosis and treatment of the hematoma in 11 patients seen in our hospital.Methods Of the 11 patients (8 males and 3 females), 2 had the hematoma involving cervical segments, 2 cervico-thoracic, 4 thoracic, 1 thoraco-lumbar, and 2 lumbar. Three patients had quadriplegia, including one with central cord syndrome; another had Brown-Sequard's syndrome; and the other seven had paraplegia. Five patients were diagnosed at our hospitals within 3-48 hours afterappearance of symptoms, and 6 patients were transferred from community hospitals within 21-106 hours after development of symptoms. Key dermal points, key muscles and the rectal sphincter were determined according to the American Spinal Injury Society Impairment Scales as scale A in two patients,B in 5 and C in 4. Emergency MRI in each patient confirmed that the dura mater was compressed in the spinal canal, with equal intensity or hyperintensity on T1 weighted image and mixed hyperintensity on T2 weighted image. Preventive and curative measures were taken preoperatively and emergency operation was performed in all patients. Open laminoplasty was done at the cervical and cervico-thoracic segments, laminectomy at the thoracic segments, laminectomy with pedicle screw fixation at the thoraco-lumbar and lumbar segments involving multiple levels, and double-sided laminectomy with the integrity of articular processes at the lumbar segments involving only a single level. During the operation, special attention was given to hematoma evacuation, hemostasis and drainage tube placement.Results Neither uncontrollable hemorrhage nor postoperative complications occurred. All patients were followed up for 1-6 years. A marked difference was noted between

    Full Text Available The purpose of this study was to determine the analgesic efficacy and clinical effects of morphine, fentanyl, methadone, lidocaine, lidocaine with epinephrine and saline (control when injected epidurally into the caudal epidural space in cattle. Epidural analgesia was achieved in five cattle on five successive occasions at weekly intervals. Analgesia was defined as a lack of response to hemostat pressure and pinprick in the skin of the perineal area and ventral aspect of the tail. The results demonstrated that while epidural lidocaine and lidocaine with epinephrine decreased the response to hemostat and pinprick compared to control, there was no reduction in response after the administration of morphine, methadone or fentanyl. Heart rate, pulse and respiratory rates were not significantly altered by any of the drugs. Neither did the drugs produce any change in the electrocardiogram (ECG of the animals.

    1977-03-01

    The authors recently operated on a boy four years of age with acute epidural hematoma showing an extravasation on the cerebral angiogram. The hematoma (hematoma volume 125 ml) was evacuated 7 hours after the head injury. The postoperative course was quite uneventful, and he was discharged a month after surgery without any neurologic deficits. The authors reviewed the literature and found 4 cases of acute epidural hematoma with extravasations in infants and children. In all cases the operative results were good. The age incidence and frequency of occurence overall for acute epidural hematomas, extravasations on cerebral angiograms and their mechanism, and the length of time from injury to operation were also discussed. It should be emphasized that, for acute epidural hematoma in infants and children, the early diagnosis and early surgery are essential to save the patients.

    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.

    2010-06-01

    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.

    Objective: To observe changes of plasma catecholamine (CA) level in patients experiencing cholecystectomy under acupuncture anesthesia combined with epidural administration of small dose of anesthetics. Methods:33 cholecystectomy patients were randomly divided into acupuncture combined with epidural anesthesia (A) group (n = 11), acupoint-skin electrical stimulation combined with epidural anesthesia (B) group (n= 11 ) and simple epidural anesthesia (C) group (n= 11). Acupoints used were bilateral Zusanli (ST 36) and Neiguan (PC 6) and stimulated with parameters of frequency 2/15 Hz, intermittent waves, electric current 2~3 mA for group A and 13mA for group B. Extradural anesthetic administered was 1.5% Lidocaine 5 mL. Venous blood samples were collected one day before,NE of group A and B lowered in comparison with pre-operation, particularly group A (P <0.01), while in group C,plasma NE level increased slightly; plasma E of group A and B increased significantly compared with pre-operation (P levels recovered basically in comparison with those of one day before operation. It indicates that acupuncture or acupoint-skin electrical stimulation is capable of regulating sympathetic activity during epidural anesthesia. The anesthetic effec t has a closer relation with changes of plasma NE level rather than changes of plasma E or DA levels. C_onclusion:Acupuncture or acupoint-surface electrical stimulation combined with epidural anesthesia may be of reducing or releasing surgical operation generated stress response during cholecystectomy.

    Full Text Available This study was performed to investigate the analgesic effect of lidocaine and a combination of lidocaine and ketamine following epidural administration in dromedary camels. Ten 12–18-month-old camels were randomly divided into two equal groups. In group L, the animals received 2% lidocaine (0.22 mg/kg and in group LK the animals received a mixture of 10% ketamine (1 mg/kg and 2% lidocaine (0.22 mg/kg administered into the first intercoccygeal (Co1–Co2 epidural space while standing. Onset time and duration of caudal analgesia, sedation level and ataxia were recorded after drug administration. Data were analysed by U Mann-Whitney tests and significance was taken as p < 0.05. The results showed that epidural lidocaine and co-administration of lidocaine and ketamine produced complete analgesia in the tail, anus and perineum. Epidural administration of the lidocaine-ketamine mixture resulted in mild to moderate sedation, whilst the animals that received epidural lidocaine alone were alert and nervous during the study. Ataxia was observed in all test subjects and was slightly more severe in camels that received the lidocaine-ketamine mixture. It was concluded that epidural administration of lidocaine plus ketamine resulted in longer caudal analgesia in standing conscious dromedary camels compared with the effect of administering lidocaine alone.

    Full Text Available In order to determine the analgesic and cardiovascular effects of the combination of epidural ketamine and lidocaine, 6 sedated cats were studied. Six healthy, young cats were used in a prospective randomised study. Each cat underwent 3 treatments, at least 1 week apart, via epidural injection: (1 ketamine (2.5 mg/kg, (2 lidocaine (4.0 mg/kg, and (3 ketamine (2.5 mg/kg plus lidocaine (4.0 mg/kg. Epidural injections were administered through the lumbosacral space. Analgesia, motor block, sedation, heart rate, arterial blood pressure, respiratory rate and arterial oxygen saturation were measured. Rectal temperature was compared before and after sedation as well as after epidural administration of the drugs. Epidural administration of the ketamine/lidocaine combination induced prolonged analgesia extending from the coccygeal to the T13-L1 dermatomes, leading to severe ataxia. Cardiovascular effects were significant in all treatments: heart rate decreased, but there was a minimal reduction in arterial pressure. It was concluded that adding a dose of ketamine to epidural lidocaine in cats is feasible and effective.

    Spinal epidural abscess (SEA) is a rare infection associated with well-established risk factors mainly in adults. We describe an 11-year-old girl without any known risk factors who presented with fever and localized spinal tenderness in the lumbar area and was diagnosed with spinal MRI as suffering from a posterior SEA extending between T11 and L4. She was successfully managed with sequential intravenous and oral antibiotics along with minimally invasive surgery without laminectomy. Methicillin-sensitive Staphylococcus aureus was the responsible pathogen isolated at surgery. Immediate institution of antibiotics, spinal MRI, and well-timed neurosurgical consultation are mandatory for a favorable outcome in cases of SEA in children.

    Holocord spinal epidural abscess (SEA) is a rare condition. To our knowledge, five cases of SEA have been reported so far, and no consensus has been made on the treatment yet. In this article, we report a case of holocord SEA and review literature to further understanding of SEA. The advent of antibiotic treatment and the recognition of surgical debridement have been important in searching for alternatives to recovery, so the patient was treated surgically together with systemic antibiotics. The patient remained neurologically stable and continued to be clinically in good condition without any low back pain after 1 year. Surgical drainage, together with systemic antibiotics, is the main treatment choice for extensive SEAs. Although treatment should be considered that highlights the importance of examining the factors related to the health and condition of the patients and the anatomy and extent of the abscess, early surgical treatment associated with prolonged antibiotic treatment is necessary.

    An 86-year-old woman was scheduled to undergo aortic valve replacement and coronary artery bypass graft. On postoperative day 3, she developed sudden-onset neck pain followed by weakness in the right arm. Her symptoms worsened with time, and she developed paraplegia. At 60 h after the first complaint, spontaneous spinal epidural hematoma (SSEH) from C2 to C6 with spinal cord compression was diagnosed from a magnetic resonance image of the cervical region. We decided on conservative therapy because operative recovery was impossible. Delayed diagnosis led to grievous results in the present case. When neurological abnormalities follow neck or back pain after open heart surgery, SSEH must be considered in the differential diagnosis. Further, if it is suspected, early cervical computed tomography/magnetic resonance imaging and surgery should be considered.

    We report a rare case of a patient with spinal epidural hematoma who presented with transient hemiplegia. A 90-year-old man awakened from sleep due to sudden neck pain. Fifteen minutes later, the man experienced progressively worsening weakness in his left hand, and was transported in an ambulance to our hospital. At the hospital, he presented with hemiplegia, and we suspected intracranial disease. Therefore, we performed magnetic resonance imaging (MRI), which revealed no intracranial lesions. Shortly after the MRI, the patient showed no signs of hemiplegia. However, since the severe neck pain persisted, we performed cervical MRI, which showed a high-intensity area at the C2-C5 level, predominantly on the left side. Despite recovery from hemiplegia, we performed a laminectomy of C3-C5 with evacuation of a hematoma at the C2-C6 level. After the surgery, the patient had no neck pain.

    Full Text Available BACKGROUND: There are always efforts to find a better and safer local anaesthetic along with adjuvants in epidural anaesthesia. Bupivacaine is a long acting , effective local anaesthetic that is commonly administered in anaesthesia practice. Despite its undoubted efficacy, bupivacaine is associated with cardiotoxicity and neurotoxicity. Central nervous system (CNS and cardiovascular adverse reactions reported after inadvertent intravascular or intravenous regional anesthesia have been linked to R (+ isomer of bupivacaine. So Levobupivacaine, the pure S ( - – enantiomer of racemic bupivacaine, was developed as an alternative to bupivacaine. Levobupivacaine is increasingly used in the clinical practice because of its safer pharmacological profile and faster protein binding rate AIM: This study was conducted to evaluate the onset and duration of analgesia, extent and duration of sensory and motor block, sedation and side effects of Dexmedetomidine and Clonidine when used as adjuvants to Levobupivacaine in epidural anaesthesia for lower limb orthopaedic surgeries. MATERIALS AND METHODS: A prospective randomized study was carried out in the department of Anaesthesia at Rajarajeswari Medical College and Hospital which included 50 adult patients between the ages of 21 and 60 years (o f ASA I/II grade who underwent lower limb orthopaedic surgeries. The patients were randomly allocated into two groups; levobupivacaine + dexmedetomidine (LD and levobupivacaine + clonidine (LC, comprising of 25 patients each. Group LD was administered 18 ml of 0.5% epidural levobupivacaine and 1.5 μg/kg of dexmedetomidine, while group LC received admixture of 18 ml of 0.5% levobupivacaine and 2 μg/kg of Clonidine . Onset of analgesia, sensory and motor block levels, sedation, duration of analgesia and side effects were observed. STATISTICAL ANALYSIS: The data obtained was subjected to statistical analysis using analysis of variance, student t test, chi - square test

    In a randomised double-blind study of 20 patients with chronic pain, epidural morphine 5 mg in 5 ml of saline was compared with epidural clonidine 150 micrograms in 5 ml of saline. Thirteen patients had a clinical and radiological diagnosis of arachnoiditis, 6 had low back pain and 1 had post-operative scar pain. There were 18 females and 2 males with an average age of 52 years, range 22-76 years. There was no difference found between the 2 solutions in the resultant analgesia measured by the visual analogue scale for pain, pain relief or the pain word score during the 3 h period of the study. No difference was found in the patient's mood which was also measured with the visual analogue scale. Two patients had no analgesia from either injection, 2 patients did not obtain any relief from clonidine and another 2 obtained no relief from morphine. Six patients reported that clonidine was better than morphine, 5 reported that morphine and clonidine were the same and 3 reported that morphine was better than clonidine. The duration of analgesia from the clonidine varied from 6 h to 1 month; the duration of analgesia from morphine varied from 6 to 24 h. Clonidine was associated with sedation and a fall in blood pressure of greater than 20 mm Hg in all patients, 1 patient required ephedrine to treat hypotension. Twelve patients had pruritus, 7 nausea and 2 vomiting following the morphine. Statistically there was no difference found between morphine and clonidine for short-term (3 h) analgesia in these patients.(ABSTRACT TRUNCATED AT 250 WORDS)

    This paper describes the functionality of the Integral System of Information for the Diagnosis of Predictive Maintenance (SIIDMP) in the thermoelectric centrals, whose primary target is to give support to the personnel related with the maintenance and operation of the thermoelectric central to optimize the application of the inspection, maintenance and its associated costs. It is important to comment that in the generating power stations of Comision Federal de Electricidad (CFE) techniques and methodologies for the preventive and corrective maintenance are applied, in addition of which they count on electronic equipment of operation dedicated to the inspection and control of vibratory equipment. The architecture of the SIIDMP is of the client-server type and for its design and implantation Windows NT 4.0 was used as operating system, SQL Server 7.0 as server and manager of the database, Visual C++ for the programs of data mining, Vision Basic 6.0 for the codification of the application programs and Interface Man-Machine (IMM), the communication mechanism Open Data Base Connectivity (ODBC) to establish the connection with the different data sources, as well as libraries of symbols and graphs that were included in the interface of the user. The main objective of the SIIDMP is to take care of the own necessities on optimization, improvements and savings in the operation of the power stations. With systems like the SIIDMP, a reduction of the costs due to shutdowns by accidental failures of the main equipment is looked for, limiting the deterioration of the equipment, as well as to provide knowledge and aid to all the personnel who take part in the management of the operation and conservation of the facilities of the power station.

Iran J Child Neurol. 2013  Spring;7(2:47-50.Abstract Spontaneous ventral spinal epidural hematomas are extremely rare in children and clinically recognized by the appearance of acute asymmetric focal motor and sensory involvement. In infants, the initial presenting symptoms are very non-specific and irritability is often the only initial manifestation. Appearance of other neurological signs may be delayed up to hours or even days later. In the absence of significant precipitating factors such as severe trauma or previously known coagulopathies,the diagnosis is usually delayed until the full picture of severe cord compression is developed. The diagnosis is finally made by performing magnetic resonance imaging. We report a 5-month-old infant with spinal epidural hematoma who presented with symmetrical upper limb weakness and diaphragmatic involvement to highlight the importance of recognizing the atypical manifestations for early diagnosis andintervention. References:1.

    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.

    Objective: To study clinical effect and anesthetic method of acupuncture anesthesia combined with epidural administration of smadose of anesthetic for cholecystectomy. Methods: A total of 194 cases of cholecystectomy patients were randomly divided into acupuncture combined with epidural anesthesia group (group A, n=66), acupoint-skin electrical stimulation combined with epidural anesthesia group (group B, n = 63) and simple epidural anesthesia group (group C, n=65). Observations were conducted using single-bland method. Bilateral Neiguan (PC 6) and Zusanli (ST 36) were punctured and stimulated electrically in group A and only stimulated electrically via cutaneous electrodes in group B. Epidural anesthetic used was 1.5% Lidocaine and the anesthetic level was controlled to reach T4~11. Results: The class-I (excellent) rates of group A, B and C were 75.76%, 60.32% and 13.85% respectively, showing significant differences between group A and C and group B and C ( P < 0. 001 ). The initial dose, doses of every hour and every case of group A and B were lower than those of group C. The dose of every hour of group C was 36.23% and 3.75 % higher than group A and B respectively ( P < 0. 001 ), suggesting that acupuncture or acu-point-skin electrical stimulation could strengthen anesthetic effect and reduce the dose of epidural anesthetic. During operation, indexes of the life signs as HR, MAP, RR, TV, MV, SpO2 and ECG kept basically stable and all patients in group A passed surgical operation safely. Conclusion: Acupuncture or acupoint-skin electrical stimulation combined with epidural anesthesia can be used as one of the anesthetic methods for cholecystectomy.

    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.

Este cuadro suele ser reconocido como lumbalgia o lumbociática. En su forma clínica más común se observa mejoría rápida y solo presentan síntomas persistentes 5-10% de los casos (1. En la década de 1990 en EEUU, el sector salud registró costes estimados en miles de millones de dólares destinados al tratamiento del dolor lumbar, y teniendo en cuenta la tendencia a la búsqueda de una mayor expectativa de vida de la población, solo se puede esperar que los costes aumenten (2,3. El tratamiento comienza generalmente con medidas conservadoras, tales como medicación oral y terapia física, y puede incluir múltiples opciones intervencionistas invasivas para controlar el dolor. En ciertas ocasiones es necesario recurrir a cirugía para los pacientes que tienen déficit neurológico progresivo o para aquellos que están refractarios a otras terapéuticas. A veces el médico se encuentra frente a un dilema, después de una primera cirugía, con respecto a si se debería repetir la cirugía o intentar otra técnica alternativa. Este es el principal problema en el cual la liberación epidural de adherencias puede permitir "evitar cirugías".

    Seventy elderly males received lumbar epidural anaesthesia with 12 ml of 2% lidocaine containing fentanyl 50 mug. At the end of transurethral surgery, the washout group (n = 33) received an epidural bolus of 30 ml saline while the control group (n = 34) did not. Mean (SD) times to 1-grade (17.2 (11.9) vs 32.7 (11.3) min) and 2-grade regression (23.8 (12.2) vs 56.0 (23.9) min) of motor block, 3-dermatomal sensory regression (31.4 (11.6) vs 42.2 (14.4) min for cold and 30.8 (15.6) vs 40.6 (14.2) min for pinprick), and regression to S1 (57.7 (16.1) vs 76.2 (20.2) min for cold and 56.8 (17.3) vs 69.2 (16.2) min for pinprick) were significantly shorter in the washout group than the control group. There were no differences in postoperative pain scores and side effects between the two groups. We concluded that epidural washout facilitates regression of both motor and sensory block following epidural anaesthesia without reducing the postoperative analgesic benefit.

    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.)

    Full Text Available Background: Epidural application of morphine has been used for postoperative analgesia following spine surgery but short duration of action of single application limits its widespread use. Materials and Methods: One hundred and fifty patients undergoing lumbar laminectomy were randomly allocated to two groups of 75 patients each. Anesthetic technique was standardized in both the groups. In Group I, at the completion of laminectomy, a 5 × 1-cm strip of gelfoam soaked in 5 mg morphine (1 mg/ml was contoured to be placed in the epidural space whereas, in group II, gelfoam soaked in saline was placed in the epidural space and 5 mg morphine (1mg/ml was instilled over the intact epidural space. Analgesic consumption for 48 hours, time-of first analgesic request, time of ambulation, time of discharge from post anesthesia care unit (PACU and hospital and adverse effects were recorded. The data was analyzed using appropriate statistical tests. Results: Mean analgesic consumption in 48 hours was significantly less in group I (8.47 ± 3.674 mg as compared to group II (24.80 ± 6.009 mg. Supplemental analgesia was requested at 30.03 ± 6.796 hours in Group I, vs 10.25 ± 2.243 in group II (P 0.01. Conclusion: Epidural application of morphine soaked in gelfoam is an effective method for prolonging the postoperative analgesia after spine surgery.

    Full Text Available Background. Lower back pain is a common reason for disability and the most common cause is lumbar disc herniation. Percutaneous epidural adhesiolysis has been applied to relieve pain and increase the functional capacity of patients who present this condition. Objectives. In this study, we retrospectively evaluated the factors which predict the outcome of percutaneous epidural adhesiolysis in patients who were diagnosed with lumbar disc herniation. Methods. Electronic medical records of patients diagnosed with lumbar disc herniation who have received percutaneous epidural adhesiolysis treatment were reviewed. The primary outcome was the factors that were associated with substantial response of ≥4 points or ≥50% of pain relief in the numerical rating scale pain score 12 months after the treatment. Results. Multivariate logistic regression analysis demonstrated that the presence of high-intensity zone (HIZ at magnetic resonance imaging was a predictor of substantial response to percutaneous epidural adhesiolysis for 12 months (P=0.007. The presence of a condition involving the vertebral foramen was a predictor for unsuccessful response after 12 months (P=0.02. Discussion and Conclusion. The presence of HIZ was a predictor of favorable long-term outcome after percutaneous epidural adhesiolysis for the treatment of lower back pain with radicular pain caused by lumbar disc herniation.

    Epidural anesthesia is a common anesthesia method yet up to 10% of procedures fail to provide adequate analgesia. This is usually due to misinterpreting the tactile information derived from the advancing needle through the complex tissue planes. Incorrect placement also can cause dural puncture and neural injury. We developed an optic system capable of reliably identifying tissue planes surrounding the epidural space. However the new technology was too large and cumbersome for practical clinical use. We present a miniaturized version of our optic system using chip technology (first generation CMOS-based system) for logic functions. The new system was connected to an alarm that was triggered once the optic properties of the epidural were identified. The aims of this study were to test our miniaturized system in a porcine model and describe the technology to build this new clinical tool. Our system was tested in a porcine model and identified the epidural space in the lumbar, low and high thoracic regions of the spine. The new technology identified the epidural space in all but 1 of 46 attempts. Experimental results from our fabricated integrated circuit and animal study show the new tool has future clinical potential.

    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.

    Full Text Available Epidural anesthesia is a common anesthesia method yet up to 10% of procedures fail to provide adequate analgesia. This is usually due to misinterpreting the tactile information derived from the advancing needle through the complex tissue planes. Incorrect placement also can cause dural puncture and neural injury. We developed an optic system capable of reliably identifying tissue planes surrounding the epidural space. However the new technology was too large and cumbersome for practical clinical use. We present a miniaturized version of our optic system using chip technology (first generation CMOS-based system for logic functions. The new system was connected to an alarm that was triggered once the optic properties of the epidural were identified. The aims of this study were to test our miniaturized system in a porcine model and describe the technology to build this new clinical tool. Our system was tested in a porcine model and identified the epidural space in the lumbar, low and high thoracic regions of the spine. The new technology identified the epidural space in all but 1 of 46 attempts. Experimental results from our fabricated integrated circuit and animal study show the new tool has future clinical potential.

  13. Labor analgesia: An update on the effect of epidural analgesia on labor outcome

    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.

    Full Text Available In clinical experience sufentanil is more effective when given epidurally than intrathecally and intravenously. To test this hypothesis we compare the analgesic characteristic of 10μgm of epidural, intrathecal and intravenous single shot sufenta nil for pain relieve after elective lower limb surgeries. A randomized double blind trial was conducted on 60 patients who were under - going elective lower limb surgery in epidural anesthesia with bupivacaine. In recovery room as soon as pain score higher than 3 on the scale of 10 on visual analogue score was reported 10μgm intravenous, intrathecal and epidural was given respectively. We concluded that epidural sufentanil is better as compared to intrathecal and intravenous in terms of duration of pain reli ef, vital complications and side effects for post - operative pain relief.

    2016-01-01

    Abstract Rationale: Ingestion of a fishbone is a common cause of esophageal injury, but spinal epidural abscess (SEA) is a rare condition due to the esophageal penetration by a swallowed fishbone. Prompt diagnosis can be seldom made owing to incomplete patient history taking and difficulties in imaging evidence identification. Patient concerns: We describe the case of a 62-year-old woman who was stuck in her throat by a fishbone, and complained of back pain, paresis of the lower limbs and fever, successively. To our knowledge, this is the first case report that we know of thoracic SEA caused by fishbone perforation. Diagnoses: About 20 days after the onset of severe back pain, she was diagnosed with SEA based on the clinical presentation and imaging findings. Interventions: Antibiotic therapy and rehabilitation therapy were carried out afterwards. However, due to exacerbation of her condition, surgical intervention had to be taken eventually. Outcomes: It is quite unfortunate for this patient to have a poor prognosis due to a delayed diagnosis and an improper management. Lessons: A number of lessons can be learnt from this case.

    Background: Spinal hematomas are rare entities that can be the cause of an acute spinal cord compression syndrome. Therefore, an early diagnosis is of great importance. Patients and Methods: From 2001 to 2005 seven patients with intense back pain and/or acute progressive neurological deficit were studied via 1.5 T MRI (in axial and sagittal T1- and T2-weighted sequences). Follow-up MRI was obtained in six patients. Results: Four patients showed the MRI features of a hyperacute spinal hematoma (two spinal subdural hematoma [SSH] and two spinal epidural hematoma [SEH]), isointense to the spinal cord on T1- and hyperintense on T2-weighted sequences. One patient had an early subacute SEH manifest as heterogeneous signal intensity with areas of high signal intensity on T1- and T2-weighted images. Another patient had a late subacute SSH with high signal intensity on T1- and T2-weighted sequences. The final patient had a SEH in the late chronic phase being hypointense on T1- and T2-weighted sequences. Discussion: MRI is valuable in diagnosing the presence, location and extent of spinal hematomas. Hyperacute spinal hematoma and the differentiation between SSH and SEH are particular diagnostic challenges. In addition, MRI is an important tool in the follow-up in patients with conservative treatment.

    To determine the value of bilobate anterior epidrual extension(AEE) on MRI in differential diagnosis of tuberculous spondylitis, pyogenic spondylitis and malignant tumor. SE T1-, T2- and Gd-DTPA enhanced T1-weighted, sagittal and axial MR images of 39 patients(40 vertebral lesions), including 16 tuberculous spondylitis, 7 pyogenic spondylitis(8 lesions, consisting of 2 separate lesion of 1 patient), and 16 malignant vertebral tumors(15 metastases, 1 lymphoma) with an AEE were reviewed. The frequency of bilobate AEE shown as double-convexity in the anterior epidural space on axial scans was evaluated in the above vertebral diseases. The bilobate AEE on the axial scans was seen in 12 out of the 16 tuberculous spondylitis(75%) and 1 out of 8 pyogenic spondylitis(13%), and 10 out of the 16 malignant tumor including 15 metastasis and 1 lymphoma(63%). The bilobate AEE of vertebral lesions is suggestive of tuberculous spondylitis or malignant tumor rather than pyogenic spondylitis. This pattern seems to be related with the preservation of the structures, including midline septum, PLL(Posterior longitudinal ligament), lateral membrane and fibrous membrane, limiting and surrounding the extension of the tuberculous spondylitis and malignant tumor, and with the early penetration or disruption of PLL, midline septum, lateral and fibrous membranes in the pyogenic spondylitis.

    Full Text Available Takayasu’s arteritis is a rare, progressive panendarteritis involving all layers of the arterial wall. This disease includes variable involvement of the aorta and its major branches. The most common complication with this condition is severe, uncontrolled hypertension, often leading to end organ dysfunction. We describe the management of a 27-year-old woman diagnosed with Takayasu’s arteritis that presented in labor with intense pain and underwent a combined spinal-epidural for anesthetic management. Per literature review, a combined spinal-epidural technique for planned vaginal delivery has not been described for a laboring Takayasu patient. Our technique, utilizing intrathecal opioids and a low-dose local anesthetic-opioid epidural infusion, provided adequate analgesia while maintaining hemodynamic stability throughout labor augmentation and successful vaginal delivery.

    To date, this is the first reported case of the surgical management of a holocord epidural abscess done through level-skipping laminectomies. It is also the first reported case of these laminectomies being performed via an alternating side unilateral approach for this condition. A 51-year-old patient presenting with progressive lower extremity weakness secondary to a spinal epidural abscess extending from C4 to S1. A minimally disruptive method of relieving the spinal cord compression via evacuation of the abscess was employed successfully. This report demonstrates the efficacy of level skipping laminectomies via a unilateral approach for holocord epidural abscesses (extending 20 vertebral levels). Performing the laminectomies via a unilateral approach as well as alternating the side of the approach minimized iatrogenic instability risk. Both strategies were designed to minimize incision size, tissue disruption, and the amount of muscular weakness/imbalance postoperatively.

    A 10-day-old girl who initially presented with fever developed over five days a complete paresis of both upper arms and swallowing difficulty. After emergency drainage of a retropharyngeal abscess, cervical US demonstrated a cervical anterior epidural mass compressing the cord. MRI confirmed the diagnosis of spinal epidural abscess secondary to C4-C5 spondylodiscitis. Surgical removal of the abscess was followed by complete disappearance of the neurologic symptoms after six months of follow-up. This is the first case of spinal epidural abscess in a newborn to be diagnosed by US and MRI preoperatively. The advantages of these non-invasive imaging modalities are discussed, and compared to myelography. (orig.).

    Full Text Available Caudal epidural anesthesia in children is not performed in pure form, but only in combination with superficial general anesthesia. Therefore, a search for reliable evaluation criteria of the caudal epidural block onset in children remains actual. Aim. To evaluate effectiveness of caudal epidural anesthesia efficacy by measurement of feet skin temperature in children. Methods and results. We investigated feet skin temperature before the caudal blockade by bupivacaine and after 15–20 minutes in 30 children. The control group included 20 children who underwent total intravenous anesthesia. The study showed that feet skin temperature after caudal blockade significantly increased from 30,1±0,15°C to 33,0±0,1°C (10% and in the control group it did not change significantly. Conclusion. Thus, feet skin thermometry may be considered to be a reliable non-invasive method for assessing the onset of the caudal block.

  8. Technique of fiber optics used to localize epidural space in piglets.

    2010-05-24

    Technique of loss-of-resistance in epidural block is commonly used for epidural anesthesia in humans with approximately 90% successful rate. However, it may be one of the most difficult procedures to learn for anesthesia residents in hospital. A two-wavelength (650 nm and 532 nm) fiber-optical method has been developed according to the characteristic reflectance spectra of ex-vivo porcine tissues, which are associated with the needle insertion to localize the epidural space (ES). In an in-vivo study in piglets showed that the reflected lights from ES and its surrounding tissue ligamentum flavum (LF) are highly distinguishable. This indicates that this technique has potential to localize the ES on the spot without the help of additional guiding assistance.

    Full Text Available Sponaneous spinal epidural haematoma (SSEH is an uncommon cause of spinal cord compression. It may be associated with various causative factors, but in many patients, anticoagulation can be implicated. SSEH should be suspected in any patient receiving anticoagulant agents who complains of l imb weakness, sensory deficits and / or urinary retention. Early diagnosis and treatment are very important for the functional recovery of the patient. Spinal magnetic resonance imaging is the most suitable neuroradiological method for early diagnosis. Alt hough primary management is the surgical evacuation of spinal epidural haematoma via laminectomy, rare cases in which the patient is improving rapidly and progressively could be treated conservatively. A 45 - yr - old woman with a spontaneous spinal epidural h aematoma who was receiving acenocoumarol treatment for a mechanical mitral valve who improved with conservative management is presented in this article.

    Full Text Available Coincidence of isolated testicular abscess and epidural-paravertebral abscess is a rare complication of brucellosis. A 24-year-old male patient was admitted to our clinic with 2 months ongoing back pain, night sweats and left scrotal pain. Septal cystic lesion with dense content in the left testis was considered to isolated testicular abscess in scrotal Doppler examination. Multiple spinal epidural and right paraspinal abscess were detected in the spinal magnetic resonance imaging. The patient was treated with drainage of abscess and oral antibiotics. The rare combination of spinal epidural and testicular abscess should be kept in the mind if a patient presented with low back pain and scrotal pain in regions where brucellosis was endemic.

    Background and Aims: Ultrasound imaging before neuraxial blocks was reported to improve the ease of insertion and minimize the traumatic trials. However, the data about the use of ultrasound in thoracic epidural block are scanty. In this study, pre-insertion ultrasound scanning was compared to traditional manual palpation technique for insertion of the thoracic epidural catheter in abdominal operations. Subjects and Methods: Forty-eight patients scheduled to midline laparotomy under combined general anesthesia with thoracic epidural analgesia were included in the study. Patients were divided into two groups with regard to technique of epidural catheter insertion; ultrasound group (done ultrasound screening to determine the needle insertion point, angle of insertion, and depth of epidural space) and manual palpation group (used the traditional manual palpation technique). Number of puncture attempts, number of puncture levels, and number of needle redirection attempts were reported. Time of catheter insertion and complications were also reported in both groups. Results: Ultrasound group showed lower number of puncture attempts (1 [1, 1.25] vs. 1.5 [1, 2.75], P = 0.008), puncture levels (1 (1, 1) vs. 1 [1, 2], P = 0.002), and needle redirection attempts (0 [0, 2.25] vs. 3.5 [2, 5], P = 0.00). Ultrasound-guided group showed shorter time for catheter insertion compared to manual palpation group (140 ± 24 s vs. 213 ± 71 s P = 0.00). Conclusion: Preprocedural ultrasound imaging increased the incidence of first pass success in thoracic epidural catheter insertion and reduced the catheter insertion time compared to manual palpation method.

    Epidural abscess of the spinal column is a rare condition that can be fatal if left untreated. It promptly progresses and can cause neurologic paralysis, urinary retention or cauda equina syndrome. Compromised immune system that occurs in patients with diabetes mellitus, AIDS, chronic renal failure, alcoholism, or cancer is a predisposing factor. It mostly occurs in adults. Here we would like to report a case of spontaneous pyogenic lumbar epidural abscess with neurological deficit diagnosed in a 15 year old boy. We treated this case successfully with surgical microscopic decompression and drainage.

    Full Text Available The treatment of chronic back pain is a challenging problem. Facet joint infiltration is an established treatment for chronic low back pain caused by arthrosis of the lumbar facet joints. Due to the increasing number of patients with chronic low back pain, this therapy has become more frequent. We treated a 51-year-old male patient, who developed an epidural hematoma 2 months after infiltration therapy. Our case shows that even a delayed onset of spinal epidural hematoma is possible and should be kept in mind as a possible cause of acute myelopathy after spinal intervention.

    An uncommon case of chronic nontraumatic spinal epidural hematoma of the lumbar spine in a 75-year-old woman is reported. The patient presented with a 7-month history of low back pain and bilateral sciatica. Magnetic resonance imaging enabled a correct preoperative diagnosis revealing a nodular, well-circumscribed epidural mass with peripheral enhancement and signal intensities consistent with chronic hematoma, which extended from L2 to L3. Laminectomy of L2-L3 was performed and the hematoma was totally resected. Histological examination of the surgical specimen demonstrated a chronic encapsulated hematoma. No evidence of vascular malformation was found. The patient recovered fully after surgical treatment. (orig.)

This case illustrates how infection in a synovial joint may extend into the extradural space and might be the route of infection in more cases than has previously been recognised. (orig.)

    Full Text Available Introducción: La analgesia epidural se ha popularizado en España, tanto en su conocimiento como en su uso, a lo largo de los últimos 20 años. La elección de esta técnica analgésica por parte de la futura madre durante el trabajo de parto y el parto en Andalucía es un derecho de la mujer que, explícitamente, sólo estará limitado por sus condiciones físicas y de salud y por los recursos disponibles en el hospital en el momento del parto. Esta elección pone en relación 2 elementos: por un lado, el componente cognitivo que establece la conveniencia o no de utilizar esta técnica según los valores, percepciones, cultura, etc. de la mujer y, por otro, el componente conductual, es decir, el uso o no de la técnica en cuestión, que dependerá además de la elección de la mujer de las condiciones anteriormente mencionadas. Objetivo: Analizar qué características definen a las mujeres que, aun pudiendo, deciden no utilizar analgesia epidural durante el parto en Andalucía. Material y métodos: Para ello se ha utilizado la información proporcionada por las mujeres ingresadas por parto en los hospitales del Sistema Sanitario Público de Andalucía, contenida en las encuestas anuales de satisfacción de usuarios del sistema de atención hospitalario en esta comunidad autónoma entre los años 2000 y 2007. Con esta información se ha realizado un análisis de segmentación jerárquica que tenía por objetivo analizar el perfil de las mujeres que rechazan esta técnica analgésica. Resultados: Las principales características que definen a las mujeres que rechazan la analgesia epidural durante el parto vienen dadas por su nivel educativo, nivel de ingresos y situación laboral. Conclusiones: Las características sociales, económicas y culturales que definen el rechazo, es decir, el "tipo" de mujer que rehúsa la epidural, coinciden con el esquema de "mujer tradicional" estudiado por otros autores (que se caracteriza por tener escasos

  3. The lucid interval associated with epidural bleeding: evolving understanding.

    Science.gov (United States)

    Ganz, Jeremy C

    2013-04-01

    The aim of this paper was to elucidate the evolution of our understanding of the term "lucid interval." A number of texts were reviewed to assess their suitability for analysis. The primary requirement was that the text contain detailed descriptions of a series of patients. Details of the clinical course, the findings and timing of surgery, and, when relevant, the time of death and postmortem findings were required. Books written by Henri-François Le Dran, Percival Pott, and James Hill fulfilled these criteria. Surgical findings included the presence and type of fractures, changes in the bone, separation of periosteum, malodorous or purulent material, tense brain, and hematoma. Postmortem findings supplemented and/or complemented the surgical findings. The courses of the patients were then tabulated, and the correlation between different clinical and operative findings was thereby determined. Our understanding of a lucid interval began in the early 18th century with the work of Henri-François Le Dran and Percival Pott in London. They did not, however, demonstrate an interval without symptoms between trauma and deterioration in patients with epidural hematomas (EDHs). The interval they described was longer than usually expected with EDHs and occurred exclusively in patients who had a posttraumatic infection. In 1751, James Hill, from Dumfries, Scotland, described the first hematoma-related lucid interval in a patient with a subdural hematoma. The first case of a lucid interval associated with an EDH was described by John Abernethy. In the 19th century, Jonathan Hutchinson and Walter Jacobson described the interval as it is known today, in cases of EDH. The most recent work on the topic came from studies in Cincinnati and Oslo, where it was demonstrated that bleeding can separate dura mater and that hemorrhage into the epidural space can be shunted out via the veins. This shunting could delay the accumulation of a hematoma and thus the rise in intracranial pressure

    A methodology to carry out Reliability Centered Maintenance (RCM) studies for hydroelectric power plants is presented. The methodology is an implantation/extension of the guidelines proposed by the Engineering Society for Advanced Mobility Land, Sea and Space in the SAE-JA1012 standard. With the purpose of answering the first five questions, that are set out in that standard, the use of standard ISO14224 is strongly recommended. This approach standardizes failure mechanisms and homogenizes RCM studies with the process of collecting failure and maintenance data. The use of risk matrixes to rank the importance of each failure based on a risk criteria is also proposed. [Spanish] Se presenta una metodologia para realizar estudios de mantenimiento Basado en Confiabilidad (RCM) aplicados a la industria hidroelectrica. La metodologia es una implantacion/ extension realizada por los autores de este trabajo, de los lineamientos propuestos por la Engineering Society for Advanced Mobility Land, Sea and Space en el estandar SAE-JA1012. Para contestar las primeras cinco preguntas del estandar se propone tomar como base los modos y mecanismos de fallas de componentes documentados en la guia para recopilar datos de falla en el estandar ISO-14224. Este enfoque permite estandarizar la descripcion de mecanismos de fallas de los equipos, tanto en el estudio RCM como en el proceso de recopilacion de datos de falla y de mantenimiento, lo que permite retroalimentar el ciclo de mejora continua de los procesos RCM. Tambien se propone el uso de matrices de riesgo para jerarquizar la importancia de los mecanismos de falla con base en el nivel de riesgo.

    Full Text Available Justificación: La mayoría de las infecciones por microsporidios en el ser humano se han reportado en el tracto gastrointestinal, sin embargo, es posible hallarlos parasitando otros sitios anatómicos como el tracto genitourinario, en donde las patologías pueden variar desde uretritis hasta falla renal. Tradicionalmente esas infecciones se deben al género Encephalitozoon, parásito contra el cual el Albendazol ha demostrado ser un medicamento efectivo. Objetivo: Determinar la prevalencia de microsporidios en personas que son referidas al laboratorio para urocultivo, dados los antecedentes clínicos que presentan. Métodos: El procesamiento de las muestras incluyó su toma con técnica aséptica, su cultivo en los medios de Agar Sangre, MacConkey y Manitol - sal para su estudio por presencia de bacterias y/u hongos y la realización del antibiograma, según los parámetros establecidos por la CCSS para los urocultivos. Adicional a esto se centrifugó una alícuota de 9 ml separando 50 microlitos del sedimento urinario, al cual se le añadió igual volumen de KOH al 5%. Se hicieron frotis los cuales se fijaron con alcohol metílico una vez secos, y se tiñeron con la técnica trierómica de Weber, obviando el paso de la decoloración y la deshidratación. Resultados: Se encontró un 25% de orinas positivas por microsporidios. Los pacientes con edades entre 26 y 55 años presentaron mayor positividad. Conclusiones: El porcentaje de prevalencia encontrado (25% y el hecho de que estas infecciones pueden llegar a causar severos daños al ser humano, hacen imperativa la necesidad de realizar diagnósticos más certeros de esta parasitosis, para lo cual proponemos la tinción de Weber con la modificación presentada en este trabajo para el diagnóstico de las infecciones por microsporidios en el tracto urinario.

    Objective: This was a prospective analysis of epidural tramadol as a single analgesic agent delivered through intraoperatively placed epidural catheter for postoperative pain relief after spinal fusion procedures in terms of efficacy and cost. Materials and Methods: Twenty patients who underwent spinal fusion procedures were included in the study. After completion of the procedure, an epidural catheter was placed at the highest level of exposed dura and brought out through a separate tract. Postoperatively, tramadol was infused into the epidural space via the catheter at a dose of 1 mg/kg diluted in 10 ml of saline. The dosage frequency was arbitrarily fixed at every 6 h during the first 2 days and thereafter reduced to every 8 h after the first 2 days till day 5. Conventional intravenous analgesics were used only if additional analgesia was required as assessed by visual analog scale (VAS). Results: Patients’ VAS score was assessed every 4 h from the day of surgery. Patients with a VAS score of 6 or more were given additional analgesia in the form of intravenous paracetamol. Of the twenty patients, eight patients needed additional analgesia during the first 24 h and none required additional analgesia after the first 24 h. The median VAS score was 7 within the first 24 h and progressively declined thereafter. Epidural tramadol was noted to be many times cheaper than conventional parenteral analgesics. Conclusion: Epidural tramadol infusion is safe and effective as a standalone analgesic after open spinal fusion surgery, especially after the 1st postoperative day. Intraoperative placement of the epidural catheter is a simple way of delivering tramadol to the epidural space. The cost of analgesia after spinal fusion surgery can be reduced significantly using epidural tramadol alone. PMID:28149082

    We report on an acute epidural abscess in a 2-year-old boy, extending from the C1 level to the L5 level. The causative agent was Staphylococcus aureus as proved by pus and blood culture. The infectious source was in the scrotum. The diffuse epidural abscess was readily detected by MRI, which showed hypo-intensity in T1 WI and hyperintensity in gradient echo T2-weighted images. The abscess capsule was enhanced by Gadolinium-DTPA. The patient recovered completely after adequate treatment with antibiotics and follow up MRI showed complete disappearance of the epidural abscess. (orig.)

    Spinal epidural abscess is a collection of suppurative material that forms between the dura mater and the ligamentum flavum. If not recognized early and treated correctly, it can lead to life-threatening sepsis. Here we report the case of a female patient, 51 years of age, with difficulty walking and bilateral leg pain after having had degenerative discogenic pain for many years. The patient had occasionally received intramuscular non-steroidal anti-inflammatory drug injections. The current report is that of an unusual case of epidural abscess that formed following multiple dose of intramuscular non-steroidal anti-inflammatory drug over a 1-year period. Hematogenous or direct dissemination is the suspected cause. To prevent serious morbidity and mortality, early diagnosis is essential. Patients with localized back pain who are at risk for developing such epidural spinal abscesses should receive a magnetic resonance imaging scan with contrast enhancement without delay. The existence of predisposing factors such as intramuscular injections should be considered in the assessment of suspected spinal epidural abscess.

    A rare case of acute epidural hematoma of the posterior fossa associated with von Willebrand's disease is reported. A 9-year-old boy fell down and hit his occipital region against a floor. Soon after he came home and slept, but three hours later he began to vomit and became drowsiness. He visited our hospital and his Glasgow Coma Scale showed 13 points. CT scan on admission showed acute epidural hematoma of left posterior fossa and contusional hematoma in the right temporal lobe. The bleeding time was over 18 minutes. He had been suspected to be suffering from von Willebrand's disease two years ago. Then fresh blood, fresh frozen plasma and anti-hemophilic globulin were prepared. Ten hours after injury, the operation was begun. Fresh epidural hematoma existed as a clot beyond transverse sinus. During the procedure of dural tenting suture, diffuse bleeding from bone, muscle, subcutaneous tissue and dura occurred and it was difficult to stop the bleeding. By using fresh blood and anti-hemophilic globulin, the bleeding was controlled, and then the operation was achieved. In the postoperative course a new epidural hematoma was found in the left temporal region and a new but asymptomatic retinal hemorrhage was found in his right eye. He was discharged without any neurological deficits 25 days after operation.

    Osteomyelitis of the spine with associated spinal epidural abscess represents an uncommon entity in the pediatric population, requiring prompt evaluation and diagnosis to prevent neurological compromise. Cat scratch disease, caused by the pathogen Bartonella henselae, encompasses a wide spectrum of clinical presentations; however, an association with osteomyelitis and epidural abscess has been reported in only 4 other instances in the literature. The authors report a rare case of multifocal thoracic osteomyelitis with an epidural abscess in a patient with a biopsy-proven pathogen of cat scratch disease. A 5-year-old girl, who initially presented with vague constitutional symptoms, was diagnosed with cat scratch disease following biopsy of an inguinal lymph node. Despite appropriate antibiotics, she presented several weeks later with recurrent symptoms and back pain. Magnetic resonance imaging revealed 2 foci of osteomyelitis at T-8 and T-11 with an associated anterior epidural abscess from T-9 to T-12. Percutaneous image-guided vertebral biopsy revealed B. henselae by polymerase chain reaction analysis, and she was treated conservatively with doxycycline and rifampin with favorable clinical outcome.

    Background and Aims: This prospective, randomized, double-blind study was undertaken to establish the effect of addition of magnesium or dexmedetomidine, as an adjuvant, to epidural bupivacaine in lower limb surgeries. Materials and Methods: One hundred and twenty ASA (American Society of Anesthesiologists) class I and II patients undergoing lower limb surgeries were enrolled to receive either magnesium sulfate (Group M) or dexmedetomidine (Group D) along with epidural bupivacaine for surgical anesthesia. All the study subjects received an epidural anesthesia with 14 ml of 0.5% bupivacaine along with either MgSO4 50 mg (Group M) or dexmedetomidine 0.5 μg/kg (Group D) or saline (Group C). The onset of motor and sensory block, duration of block, hemodynamic parameters, and any adverse events were monitored. Results: Analgesia in the postoperative period was better in Group D, duration of sensory and motor blockade was significantly prolonged in Group D and incidence of sedation was more in Group D. Conclusion: Hence, addition of dexemedetomidine to epidural bupivacaine can be advantageous with respect to increased duration of motor and sensory blockade and arousable sedation. PMID:25425781

    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.

    Lumbar epidural analgesia is frequently employed to provide pain relief for women during labor. Anesthesia providers use various methods to identify the epidural space. Some providers use air, some use fluid, and others use a combination of air and fluid during the loss of resistance technique. Loss of resistance to air has been speculated to result in a lesser quality of analgesia compared with loss of resistance to only fluid. A search strategy focusing on preappraised sources was used to locate evidence from interventional and observational studies. Four evidence sources were located, including a systematic review with meta-analysis of 4 older studies. The evidence reviewed was inconclusive in determining whether a difference in analgesia quality results from the use of air or fluid during the loss of resistance technique. Future studies should include an adequate number of subjects and address other problems such as operator experience, observer blinding, equivalence of subject characteristics, outcomes definition and measurement, and composition of epidural solution. Providers should consider other factors when selecting loss of resistance medium, such as the reported complications of large amounts of air injected into the epidural space and surrounding structures.

    Non-traumatic intracranial acute epidural hematoma(EDH)is rare. It is mostly caused by coagulation disorders, dural metastasis, or vascular malformations of the dura. We report a case of non-traumatic acute EDH caused by chronic nasal sinusitis and review the literature comprising 10 cases of acute EDH caused by chronic nasal sinusitis. A 16-year-old boy visited our outpatient clinic with a 2-day history of severe headache. He did not have fever or neurological abnormalities and showed no evidence of head trauma. Cranial computed tomography(CT)revealed sphenoid sinusitis and a small amount of epidural air in the middle fossa, but no other intracranial abnormalities. After eight days with no subsequent history of trauma, radiological exams showed a massive acute epidural hematoma in the left middle fossa and temporal convexity without any vascular lesion or skull fracture. The patient underwent a hematoma evacuation that revealed neither a skull fracture nor a vascular abnormality. In this adolescent, chronic nasal sinusitis caused fragility of the meningeal artery wall, an air collection in the epidural space, and the detachment of the dura mater from the inner surface of the skull, thereby resulting in a non-traumatic acute EDH.

    Epidural stimulation (ES) of the lumbosacral spinal cord has been used to facilitate standing and voluntary movement after clinically motor-complete spinal-cord injury. It seems of importance to examine how the epidurally evoked potentials are modulated in the spinal circuitry and projected to various motor pools. We hypothesized that chronically implanted electrode arrays over the lumbosacral spinal cord can be used to assess functionally spinal circuitry linked to specific motor pools. The purpose of this study was to investigate the functional and topographic organization of compound evoked potentials induced by the stimulation. Three individuals with complete motor paralysis of the lower limbs participated in the study. The evoked potentials to epidural spinal stimulation were investigated after surgery in a supine position and in one participant, during both supine and standing, with body weight load of 60%. The stimulation was delivered with intensity from 0.5 to 10 V at a frequency of 2 Hz. Recruitment curves of evoked potentials in knee and ankle muscles were collected at three localized and two wide-field stimulation configurations. Epidural electrical stimulation of rostral and caudal areas of lumbar spinal cord resulted in a selective topographical recruitment of proximal and distal leg muscles, as revealed by both magnitude and thresholds of the evoked potentials. ES activated both afferent and efferent pathways. The components of neural pathways that can mediate motor-evoked potentials were highly dependent on the stimulation parameters and sensory conditions, suggesting a weight-bearing-induced reorganization of the spinal circuitries.

    Objective:To observe the effect of application of ropivacaine in combined with sufentanil epidural analgesia after cesarean section on the lactation and neonates.Methods:The puerpera who were underwent cesarean section with different analgesia methods were observed. The included puerpera were performed with the cesarean section under combined spinal epidural anesthesia. A total of 30 puerpera who were given ropivacaine in combined with sufentanil epidural analgesia after operation were served as the observation group, while 30 cases who were intermittently given intramuscular injection of pethidine after operation were served as the control group. The postpartum analgesic effects in the two groups were observed. The radioimmunoassay was used to detect the plasma PRL level. The postpartum colostrum time, 24 h lactation number, and NBNA scores in the two groups were compared.Results:The postoperative VAS score in the observation group was significantly lower than that in the control group (P<0.05), while the plasma PRL level was significantly higher than that in the control group (P<0.05). The postoperative colostrum time in the observation group was significantly earlier than that in the control group (P<0.05), while the lactation number was significantly greater than that in the control group (P<0.05).Conclusions:Application of ropivacaine in combined with sufentanil epidural analgesia after cesarean section can effectively alleviate the postoperative pain, and improve the lactation, with no obvious adverse reactions on the neonates and reliable effects.

    Full Text Available Introduction. Use of analgesics is an evitable and necessary part of thoracic surgery. This study was designed to compare analgesic effects of persistent thoracic epidural anesthesia versus persistent intercostal nerve block and determine their role in opioid need after thoracotomy. Methods. 116 patients above 20 years old who were candidate for thoracotomy through either posterolateral or thoracoabdominal incision were situatedin one of three group for pain relief. For the first group, pain relieved by petidine and pentazosin. In 2nd group, pain relived by thoracic epidural anesthesia with bupivacaine catheters which were inserted between costal and plural space. In 3rd group, bupivacaine was introduced through 3rd and 4th intercostal space by catheter (2 mg/kg in devided doses. Pain was meseared by visual analogue scale and quantified by surgical residents through a method bupivacaine was injected. If Bupivacaine did not relieve pain, then opioid was used as adjuvant. Results. The study showed that epidural group needed less opioids and had more cooperation in comparison with two other group. The intercostal group complained of pain at chest tube site. Discussion. In thoracotomized patients, pain control is more effective via epidural anesthesia in turns of opioid side effects, expenses and patient comfort.

    2012-07-01

    Full Text Available Abstract Background Pain relief during labour is a topic of major interest in the Netherlands. Epidural analgesia is considered to be the most effective method of pain relief and recommended as first choice. However its uptake by pregnant women is limited compared to other western countries, partly as a result of non-availability due to logistic problems. Remifentanil, a synthetic opioid, is very suitable for patient controlled analgesia. Recent studies show that epidural analgesia is superior to remifentanil patient controlled analgesia in terms of pain intensity score; however there was no difference in satisfaction with pain relief between both treatments. Methods/design The proposed study is a multicentre randomized controlled study that assesses the cost-effectiveness of remifentanil patient controlled analgesia compared to epidural analgesia. We hypothesize that remifentanil patient controlled analgesia is as effective in improving pain appreciation scores as epidural analgesia, with lower costs and easier achievement of 24 hours availability of pain relief for women in labour and efficient pain relief for those with a contraindication for epidural analgesia. Eligible women will be informed about the study and randomized before active labour has started. Women will be randomly allocated to a strategy based on epidural analgesia or on remifentanil patient controlled analgesia when they request pain relief during labour. Primary outcome is the pain appreciation score, i.e. satisfaction with pain relief. Secondary outcome parameters are costs, patient satisfaction, pain scores (pain-intensity, mode of delivery and maternal and neonatal side effects. The economic analysis will be performed from a short-term healthcare perspective. For both strategies the cost of perinatal care for mother and child, starting at the onset of labour and ending ten days after delivery, will be registered and compared.

    The reason is to give to know to the nuclear community in Mexico the good results that it located in the 2006 to the Laguna Verde Nucleo electric Central in the classification of the World Association of Nuclear Operators (WANO) like one of the best in the worldwide scale, and their Strategic Plan 2007-2011 like an opportunity to continue improving the Quality, the Competitiveness and the Excellency in their Generating Units. It stands out that the fuel reloads are carried out in systemic form in less than 30 days, and also other achievements like it is the certificate granted by PROFEPA of Clean Industry, the renovation of the Certifications of the ISO-9001 and the ISO-14001, as well as the accredit of the Laboratories, and they will give data of the project of the increment of power that their power rose in 15%. For those results in the Strategic Planning 2007-2011 are pointed out that the Laguna Verde Central is a highly viable option in Mexico, when continuing with reloads that will allow a capacity factor up of 90%, and the other concepts that will give the obtaining of the qualification level 1 of WANO in this strategic period. Finally I will conclude with the good news for the Nuclear Industry in Mexico that published the Reforma newspaper at November 01, 2006: 'To the president of Mexico, Felipe Calderon, interests him to impel during his command the alternating energy sources to the hydrocarbons, known it is that the hydrocarbons (petroleum, coal or natural gas) they are finite, while the appetite of the world for the energy is infinite.

    The Atucha II central is a heavy water power station and natural uranium. For this reason and due to the first floor reactivity excess that have this type of reactors, it is necessary to carry out a continuous fuel management and with the central in power (for the case of Atucha II every 0.7 days approximately). To maintain in operation these centrals and to achieve a good fuels economy, different types of negotiate of fuels that include areas and roads where the fuels displace inside the core are proved; it is necessary to prove the great majority of these managements in long periods in order to corroborate the behavior of the power station and the burnt of extraction of the fuel elements. To carry out this work it is of great help that a program implements the approaches to continue in each replacement, using the roads and areas of each administration type to prove, and this way to obtain as results the one regulations execution in the time and the average burnt of extraction of the fuel elements, being fundamental this last data for the operator company of the power station. To carry out the previous work it is necessary that a physicist with experience in fuel management proves each one of the possible managements, even those that quickly can be discarded if its don't fulfill with the regulatory standards or its possess an average extraction burnt too much low. For this it is of fundamental help that with an automatic model the different administrations are proven and lastly the physicist analyzes the more important cases. The pattern in question not only allows to program different types of roads and areas of fuel management, but rather it also foresees the possibility to disable some of the approaches. (Author)

    Full Text Available Justificación: La mayoría de las infecciones por microsporidios en el ser humano se han reportado en el tracto gastrointestinal, sin embargo, es posible hallarlos parasitando otros sitios anatómicos como el tracto genitourinario, en donde las patologías pueden variar desde uretritis hasta falla renal. Tradicionalmente esas infecciones se deben al género Encephalitozoon, parásito contra el cual el Albendazol ha demostrado ser un medicamento efectivo. Objetivo: Determinar la prevalencia de microsporidios en personas que son referidas al laboratorio para urocultivo, dados los antecedentes clínicos que presentan. Métodos: El procesamiento de las muestras incluyó su toma con técnica aséptica, su cultivo en los medios de Agar Sangre, MacConkey y Manitol - sal para su estudio por presencia de bacterias y/u hongos y la realización del antibiograma, según los parámetros establecidos por la CCSS para los urocultivos. Adicional a esto se centrifugó una alícuota de 9 ml separando 50 microlitos del sedimento urinario, al cual se le añadió igual volumen de KOH al 5%. Se hicieron frotis los cuales se fijaron con alcohol metílico una vez secos, y se tiñeron con la técnica trierómica de Weber, obviando el paso de la decoloración y la deshidratación. Resultados: Se encontró un 25% de orinas positivas por microsporidios. Los pacientes con edades entre 26 y 55 años presentaron mayor positividad. Conclusiones: El porcentaje de prevalencia encontrado (25% y el hecho de que estas infecciones pueden llegar a causar severos daños al ser humano, hacen imperativa la necesidad de realizar diagnósticos más certeros de esta parasitosis, para lo cual proponemos la tinción de Weber con la modificación presentada en este trabajo para el diagnóstico de las infecciones por microsporidios en el tracto urinario.Urine samples from patients with clinical antecedents of suspicion genitourinary pathology were studied for bacteria, fungi and for the

    Full Text Available Abstract Background Whether epidural analgesia for labor prolongs the active-first and second labor stages and increases the risk of vacuum-assisted delivery is a controversial topic. Our study was conducted to answer the question: does lumbar epidural analgesia with lidocaine affect the progress of labor in our obstetric population? Method 395 healthy, nulliparous women, at term, presented in spontaneous labor with a singleton vertex presentation. These patients were randomized to receive analgesia either, epidural with bolus doses of 1% lidocaine or intravenous, with meperidine 25 to 50 mg when their cervix was dilated to 4 centimeters. The duration of the active-first and second stages of labor and the neonatal apgar scores were recorded, in each patient. The total number of vacuum-assisted and cesarean deliveries were also measured. Results 197 women were randomized to the epidural group. 198 women were randomized to the single-dose intravenous meperidine group. There was no statistical difference in rates of vacuum-assisted delivery rate. Cesarean deliveries, as a consequence of fetal bradycardia or dystocia, did not differ significantly between the groups. Differences in the duration of the active-first and the second stages of labor were not statistically significant. The number of newborns with 1-min and 5-min Apgar scores less than 7, did not differ significantly between both analgesia groups. Conclusion Epidural analgesia with 1% lidocaine does not prolong the active-first and second stages of labor and does not increase vacuum-assisted or cesarean delivery rate.

    Objective. Our goal was to identify spatial filtering methods that would improve decoding of continuous arm movements from epidural field potentials as well as demonstrate the use of the epidural signals in a closed-loop brain-machine interface (BMI) system in monkeys. Approach. Eleven spatial filtering options were compared offline using field potentials collected from 64-channel high-density epidural arrays in monkeys. Arrays were placed over arm/hand motor cortex in which intracortical microelectrodes had previously been implanted and removed leaving focal cortical damage but no lasting motor deficits. Spatial filters tested included: no filtering, common average referencing (CAR), principle component analysis, and eight novel modifications of the common spatial pattern (CSP) algorithm. The spatial filtering method and decoder combination that performed the best offline was then used online where monkeys controlled cursor velocity using continuous wrist position decoded from epidural field potentials in real time. Main results. Optimized CSP methods improved continuous wrist position decoding accuracy by 69% over CAR and by 80% compared to no filtering. Kalman decoders performed better than linear regression decoders and benefitted from including more spatially-filtered signals but not from pre-smoothing the calculated power spectra. Conversely, linear regression decoders required fewer spatially-filtered signals and were improved by pre-smoothing the power values. The ‘position-to-velocity’ transformation used during online control enabled the animals to generate smooth closed-loop movement trajectories using the somewhat limited position information available in the epidural signals. The monkeys’ online performance significantly improved across days of closed-loop training. Significance. Most published BMI studies that use electrocorticographic signals to decode continuous limb movements either use no spatial filtering or CAR. This study suggests a

    Full Text Available Background: Establishing an epidural in an agitated laboring woman can be challenging. The ideal pain control technique in such a situation should be effective, fast acting, and short lived. We assessed the efficacy of inhalational methoxyflurane (Penthrox™ analgesia as bridging analgesia for epidural placement. Materials and Methods: Sixty-four laboring women who requested epidural analgesia with pain score of ≥7 enrolled in an observational study, 56 of which completed the study. The parturients were instructed to use the device prior to the onset of uterine contraction pain and to stop at the peak of uterine contraction, repeatedly until epidural has been successfully placed. After each (methoxyflurane inhalation-uterine contraction cycle, pain, Richmond Agitation Sedation Scale (RASS, nausea and vomiting were evaluated. Maternal and fetal hemodynamics and parturient satisfaction were recorded. Results: The mean baseline pain score was 8.2 ± 1.5 which was reduced to 6.2 ± 2.0 after the first inhalation with a mean difference of 2.0 ± 1.1 (95% confidence interval 1.7-2.3, P < 0.0001, and continued to decrease significantly over the study period (P < 0.0001. The RASS scores continuously improved after each cycle (P < 0.0001. Only 1 parturient from the cohort became lightly sedated (RASS = −1. Two parturients vomited, and no significant changes in maternal hemodynamics or fetal heart rate changes were identified during treatment. 67% of the parturients reported very good or excellent satisfaction with treatment. Conclusion: Penthrox™ provides rapid, robust, and satisfactory therapy to control pain and restlessness during epidural placement in laboring parturient.

    Full Text Available Spontaneous spinal epidural hematoma (SSEH is a rare entity.SSEH is an accumulation of blood in the vertebral epidural space in the absence of trauma or iatrogenic procedure like lumbar puncture.The incidence of SSEH has been estimated at 0.1 patients per 100,000 individuals and represents less than 1% of spinal space-occupying lesions .Here we are presenting case of a 65year old female hypertensive on treatment with controlled blood pressure, who presented with sudden onset paraplegia and weakness of muscles of hand, associated with urinary and bowel incontinence that started 6 hours before presenting to Emergency Room .Patient was subjected to MRI spine that revealed a collection in spinal epidural space ,hypointense in T1W images and hyperintense in T2W images, extending from C6-C7 to T1-T2 suggestive of acute / subacute epidural hematoma (fig 1.In our case all possible causes of an epidural haematoma were ruled out by relevant investigations.Patient was subjected to surgical evacuation of hematoma after 48 hours of presentation.Perioperative and Postoperative period was uneventfull . Sensations over involved areas improved. Motor weakness also improved from Grade III to Grade IV+ in bilateral lower limbs and from Grade II to Grade IV in small muscles of hand and triceps, however Patient persisited with urinary incontinence.CONCLUSION: When a patient receiving anticoagulant therapy complains of sudden and unexplained neck or back pain, we should suspect the possibility of SSEH. For early diagnosis, immediate MRI is essential .In addition, we should consider SSEH as one of the important differential diagnoses in elderly patients who have developed acute myelopathy.

    The on-line systems for the management of the Laguna Verde Central (CLV) have had the challenge to evolve from the PC's of first generation until emigrate to the new Internet technologies, so that they allow to the diverse work groups to have the computer tool that allows them to gather the necessary data and to carry out efficiently the analysis of their results. To confront the previous challenge, in the CLV it has been developed and implemented the Nucleo Red that is an on-line system with the objective of providing in it lines strategic information for the Technician-administrative management of the plant in the nuclear context. The Nucleo Red is the computational tool that reflects the technical administrative processes implemented by personnel of the different Operative departments, it seeks to cooperate to the reliable and efficient operation of the first nucleo electric central of Mexico, with technology and Mexican personnel the one which already it had received international recognitions. The perspective of this computer system is to continue inside the process of continuous improvement and that although it was designed for a nucleo electric plant it can also be taken to the conventional plants of generation of electric power, so that this technology can be taken advantage of in other non nuclear facilities. The objective of the present work, is to show the new modules that have been developed in the Nucleo Red, its operation in general, and the benefits that it presents its use. (Author)

    Solar installations are usually sized by using simulation programs that calculate the annual solar fraction for a given design. While theoretically well founded, these programs require exact values for all the input factors. However, much of these factors are actually uncertain, so they can not be defined by a single value. In order to work out this contradiction, we propose the use of stochastic simulation methods. A centralized solar hot water system is analysed. The uncertainties in the problem are identified, estimated and propagated through a dynamic deterministic model. Finally, a sensitivity analysis is performed so as to figure out which uncertain factors have the largest effect on the solar fraction. (Author)

An independent pain management team scoring technical success found epidural technique to be consistent. Oncological outcome was an endpoint of our study, comparing both analysis groups. We classed prostate-specific antigen (PSA recurrence after RRP as a serum PSA ≥ 0.2 ng/mL at any stage of postoperative follow-up. Complications were recorded to 30 days using the modified Clavien system, and full statistical analyses were undertaken.Results: Records were available for 239 men; we observed a decreased trend in the use of epidural for pain management, along with a decrease in average hospital stay and an overall epidural success rate of 64%. When dividing data into RRP with and without epidural, we found a median hospital stay of 7 days for patients receiving an epidural compared with 6 days for those not receiving an epidural. The differences were statistically significant (P < 0.048 and remained so after adjusting for complications (P < 0.0001. Regarding oncological outcome, PSA recurrence was further analyzed in this cohort. Percentage of recurrence was higher (14.8% for patients receiving an epidural than for the non-epidural group (4.8%.

    Although early diagnosis and treatment of spinal epidural abscess are emphasized in children in view of its prognosis, these are very difficult because of the nonspecific symptoms of the disease. A 6-year-old boy complained of lumbar pain and difficulty in walking. Computed tomography, performed 6 days after the occurrence of complaints, revealed space occupying lesion in the spinal canal and epidural space at the level of L2-S1. Subsequent single photon emission computed tomography (SPECT) with Ga-67 clearly visualized active inflammation resulting from epidural abscess. The patient received intensive chemotherapy alone. Twenty-one days later, Ga-67 uptake disappeared on SPECT images. The finding indicates the usefulness of diagnostic imagings in the early diagnosis and treatment of spinal epidural abscess, thus avoiding surgery, the role of which has been under debate.

    Full Text Available There are many studies about epidural fibrosis after surgical manipulation of the spine. We have studied formation of the post laminectomy epidural fibrosis after application of two materials (Silicone and Teflon in this report. This expriment is on two groups of rats. Two separated laminectomies were done in each rat, one serving as control while in the other laminectomy spaces Silicone was used in group A and Teflon in group B. Laminectomy spaces were evaluated with gross dissection and histologic studies after 6 weeks. Silicone decreased intermuscular scar, deep scar, dural adhesion and collagen fiber density in epidural space. Teflon decreased dural adhesion and collagen fiber density but did not decrease intermuscular and deep scar formation in epidural space.

    Full Text Available Background: Opioids are considered mainstream for combined spinal-epidural anesthesia, but frequently limited by adverse effects. The aim of this study was to examine whether low-dose spinal neostigmine, epidural dexamethasone or their combination enhances analgesia from spinal bupivacaine without adverse effects. Materials and Methods : A total of 60 patients undergoing orthopedic surgery were randomized to one of four groups and evaluated for 24-h after surgery for analgesia (time to first rescue analgesic and rescue analgesic consumption. Patients received 15 mg bupivacaine plus the test drug intrathecally (saline or 1 microgram (μg neostigmine. The epidural test drug was either saline or 10 mg dexamethasone. The Control group (CG received spinal and epidural saline. The Neostigmine group (NG, spinal neostigmine and epidural saline; the Dexamethasone group (DG, spinal saline and epidural dexamethasone; and the Neostigmine-dexamethasone group (NDG, spinal neostigmine and epidural dexamethasone. Results: The CG (282 ± 163 min and NG (524 ± 142 min were similar in their times to first rescue analgesic and analgesic consumption. The time to first rescue analgesic was longer for the DG (966 ± 397 min compared with CG and NG (P < 0.0002, and the DG had less ketoprofen consumption and lower overall visual analogue scale-pain sores compared with CG and NG (P < 0.0005. Addition of 1 mg-neostigmine (NDG resulted in longer time to rescue analgesic (1205 ± 303 min; P < 0.02 and lower ketoprofen consumption (P < 0.05 compared to DG. Sporadic cases of vesical catheterization and emesis were observed, however adverse effects were similar among groups. Conclusion: Spinal 1 microgram (μg neostigmine further enhanced analgesia from spinal bupivacaine combined with epidural dexamethasone, without increasing the incidence of adverse effects.

    We report the case of a 34-year-old woman (height: 153 cm, weight : 62.4 kg, non-pregnant weight : 52 kg, uniparous) without underlying diseases who developed pressure ulcer due to keeping a similar body position during long-term epidural delivery. Induction of childbirth was started in gestational week 40, causing reduction of fetal heart rate, which improved after adoption of a right lateral recumbent position. Severe contractions occurred and epidural labour analgesia was started. The fetal heart rate decreased again and induction of childbirth was suspended, but the right lateral recumbent position was maintained. Epidural administration was continued due to persistent contractions. Next morning, induction of childbirth was restarted and birth occurred in approximately 6 hours. The right lateral recumbent position was maintained for approximately 20 hours. At childbirth, a pressure ulcer was present in the intertrochanteric part of the right femur. The causes included insufficient knowledge of medical staff about the risk of pressure ulcer during epidural delivery, and no position change. A decreased sensation and blocked motor nerve caused by epidural anesthesia might have accelerated pressure ulcer development. This case suggests that preventive measures against pressure ulcer are required in epidural anesthesia in pregnant women.

    Full Text Available The purpose of present study was to assess the effects of thoracic epidural anesthesia on splanchnic perfusion, bacterial translocation and histopathologic changes in experimental hemorrhagic shock in short-tailed macaques (Macaca nemestrina. Sixteen Macaca nemestrinas were randomly assigned to one of two groups i.e. the lidocaine group (n = 8, receiving general anesthesia plus lidocaine thoracic epidural anesthesia; and the saline group (n = 8, receiving general anesthesia alone as control. Hemorrhagic shock was induced by withdrawing blood gradually to a mean arterial pressure (MAP of 40 mm Hg, and maintained for 60 minutes. Animals were then resuscitated with their own blood and ringer lactate solution (RL. After resuscitation, epidural lidocaine 2% was given in the lidocaine group and saline in the control group. Resuscitation that was performed after one hour hemorrhagic shock, with hemodynamic variables and urine output returned to normal, revealed there was no improvement of splanchnic perfusion. PgCO2, P(g-aCO2, and pHi remained in critical value and tended to deteriorate in the saline group. Contrast to saline group, splanchnic perfusion in lidocaine group tended to improve. This condition was supported by the finding of less bacterial translocation and better histopathologic changes in lidocaine thoracic epidural anesthesia group than in saline group. This study concludes that lidocaine thoracic epidural anesthesia attenuates splachnic hypoperfusion in post-resuscitation hemorrhagic shock in Macaca nemestrina.

    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

    Full Text Available 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 (P < 0.0001, and pain scores in the remifentanil group showed an increasing trend one hour later. The remifentanil group had a lower SpO2 (P < 0.0001 and a higher sedation score (P < 0.0001 within 30 min after treatment. The epidural group had a higher overall satisfaction score (3.8 ± 0.4 vs. 3.7 ± 0.6, P = 0.007 and pain relief score (2.9 ± 0.3 vs. 2.8 ± 0.4, P < 0.0001 compared with the remifentanil group. There was no significant difference on side effects between the two groups, except that a higher rate of dizziness (1% vs. 21.8%, P < 0.0001 was observed during remifentanil analgesia. 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

    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.

    One of the main preoccupations of the electric power generator stations is the appropriate operation of the same ones. The operators must be qualified to respond in an adequate way and to be able to take to these power stations to an optimal, sure and stable operation condition under any circumstance. The Laboratory of Analysis in Nuclear Reactors Engineering (LAIRN) of the Engineering Faculty of UNAM (Fl) in collaboration with the International Atomic Energy Agency (IAEA), it develops an interactive classroom simulator in which simulations of the phenomena which take place in a nuclear power station are executed. The classroom simulator bases its operation on specialized nuclear codes feeding interactive graphic unfolding with those that it is possible to make a monitoring, supervision and control of the behavior of the power station under any operation regime, either in normal operation, transitory events or postulated accident sequence. The development of this classroom simulator includes a modular and re configurable structure. Due to it is indispensable to count with a higher inter activity with the system it is included the simulation of the control system of the plant and inside the same, one of those more important it is the reactor pressure control system. The present work describes the conceptual design and the used methodology for the development and implementation in the simulator of a simplified model of the pressure control system for a BWR generic central. The reach of the development will allow to accomplish the necessary tests to demonstrate that this has an adequate performance according to the carried out simplifications. (Author)

    Full Text Available INTRODUCTION: Traumatic spinal cord injury is one of the most disabling conditions occurring in man and thus stimulates a strong interest in its histopathological, biochemical, and functional changes, primarily as we search for preventive and therapeutic methods. PURPOSE: To develop an experimental model for transplantation of cells from the fetal rat central nervous system to the site of an injured spinal cord of an adult rat in which the transplanted cells survive and become integrated. This experimental model will facilitate investigations of factors that promote regeneration and functional recovery after spinal cord trauma. MATERIAL AND METHODS: Fifteen adult Wistar rats underwent laminectomy, and an spinal cord lesion was made with microdissection. Fetal spinal cord tissue was then transplanted to the site of the injury. The rats were monitored over a 48-hour period, and then their vertebral column was completely removed for histological analysis. RESULTS: In 60% of transplanted rats, the fetal tissue at the injured site remained viable in the site of the lesion.INTRODUÇÃO: A lesão traumática da medula espinal consiste numa das mais incapacitantes lesões que o ser humano pode sofrer e tem despertado grande interesse no conhecimento das alterações histopatológicas, bioquímicas, funcionais e principalmente na busca de métodos de prevenção e tratamento.

    Spinal epidural abscess (SEA) is a severe pyogenic infection of the epidural space that leads to devastating neurological deficits and may be fatal. SEA is usually located in the thoracic and lumbar parts of the vertebral column and injures the spine by direct compression or local ischemia. Spinal injury may be prevented if surgical and medical interventions are implemented early. The diagnosis is difficult, because clinical symptoms are not specific and can mimic many benign conditions. The classical triad of symptoms includes back pain, fever and neurological deterioration. The gold standard in the diagnostic evaluation is magnetic resonance imaging with gadolinium enhancement, which determines the location and extent of the abscess. Increased awareness of the disease is essential for rapid recognition and immediate implementation of treatment. Here we describe the case of a 26-year-old woman with SEA with fever, back pain in the thoracic region and delayed symptoms of a transverse spinal cord injury.

Although multiple epidural regimens with varying opioids are presently used for pain management, there is currently no clinical consensus regarding which epidural regimen provides the best analgesia outcomes with the fewest side effects. This 10-year retrospective cohort study was performed to compare the quality of analgesia and the incidence of side effects associated with the three most common epidural regimens used at a tertiary care children's hospital, in patients undergoing the Nuss procedure. Methods: Seventy-two pediatric patients were identified as having been treated with one of three epidural regimens for postoperative pain management following the Nuss procedure: Group A (n=12 received 0.125% bupivacaine and 5 µg/mL fentanyl, Group B (n=21 received 0.125% bupivacaine and 10 µg/mL hydromorphone, and Group C (n=39 received 0.1% ropivacaine and 20 µg/mL hydromorphone. Our primary outcome was maximal daily pain scores (numerical rating scale 0–10, with an analytical focus on postoperative day 1 scores. The primary outcome was analyzed using linear regression. The secondary outcomes included the length of stay, side-effect profiles as reflected by the number of treatments for nausea and pruritus, pain scores according to epidural site insertion, occurrence of breakthrough pain, and presence of severe pain throughout their hospital stay. Secondary outcomes were analyzed using linear or

    The cardiovascular effects of continuous epidural administration (CEA) of lidocaine were investigated in anesthetized dogs. Loading epidural injections of 2, 4, or 6 mg/kg of lidocaine were followed by CEA with 1, 2, or 3 mg/kg/hr lidocaine, respectively, for 2 hr under 2.0% isoflurane anesthesia. Heart rate, direct blood pressure, cardiac index, and stroke volume decreased dose-dependently during CEA, whereas systemic vascular resistance did not significantly differ with dose, and no characteristic changes were observed in any groups. Plasma lidocaine concentration reached a steady state during CEA and increased in a dose-dependent manner. Circulatory suppression caused by lidocaine CEA was not attributable to peripheral vasodilation, but rather to the direct cardiac action of systemic lidocaine absorption from the peridural space.

    The morbidity and mortality associated with blunt thoracic trauma are significant and can be multisystem in nature. Of these, pulmonary complications, including ventilatory impairment secondary to pain, have been recognized to be the most consequential. Although several analgesic strategies have emerged, thoracic epidural analgesia (TEA) has arguably demonstrated superior efficacy and is used frequently in adults. Unfortunately, TEA is rarely used in children after blunt thoracic trauma, but may be of considerable benefit. This low rate of use likely reflects one or more of several factors potentially encountered when considering the use of TEA in pediatric chest wall trauma. Among them are (1) uncertainty regarding safety and efficacy; (2) the technical challenges of pediatric thoracic epidural placement, including technique and equipment concerns; and (3) drug selection, dosing, and toxicity. The following case review describes the successful application of TEA in a 4-year-old boy after multiple traumatic rib fractures and associated pneumothorax and pulmonary contusion.

    This study was performed to investigate the analgesic effect of lidocaine and a combination of lidocaine and ketamine following epidural administration in dromedary camels. Ten 12-18-month-old camels were randomly divided into two equal groups. In group L, the animals received 2% lidocaine (0.22 mg/kg) and in group LK the animals received a mixture of 10% ketamine (1 mg/kg) and 2% lidocaine (0.22 mg/kg) administered into the first intercoccygeal (Co1-Co2) epidural space while standing. Onset time and duration of caudal analgesia, sedation level and ataxia were recorded after drug administration. Data were analysed by U Mann-Whitney tests and significance was taken as p dromedary camels compared with the effect of administering lidocaine alone.

    Full Text Available One of the main tools to quantify and to qualify the forest potentials is the forest inventory. During its planning phase it is necessary to define the sampling intensity as well as the sizes and shapes of sample units to minimize data collection costs while increasing the precision of the forest inventory. This study aimed to test different sizes and shapes of sample units for different diameters at breast height (DBH size categories. The study was carried out in the Manaus region including INPA and EMBRAPA experimental station areas around BR-174 road, in the state of Amazonas, Brazil. Five categories of DBH were considered, as following: above 5cm, 10cm, 20cm, 25cm and 45cm. For all DBH categories, twenty-three different sizes were tested, from 100m2 to 10,000m2. The number of samples was defined as n = 30 for all size simulations to qualify for the use of the central limit theorem assumptions. Basal area was used to estimate uncertainty in relation to the true value of mean for comparison among different sizes for each DBH category. Almost all sample plot sizes in all categories of DAP obtained uncertainties below 10%. The best sample sizes were 1,000m 2 , 800m², 1,200m², 2,000m² and 10,000m², respectively for minimum DBH of 5, 10, 20, 25 and 45cm. Most of exploratory forest inventories in the state of Amazonas have been done for trees with DBH greater than 10cm, and sizes have varied from 1,000 to 2,000 m2. The findings of this work demonstrated that the size for exploratory inventory is adequate. However, different size should be used for DBH greater than 45cm, which is usually the minimum DBH for logging plans.

    Full Text Available Objetivos: Valorar la influencia del uso de analgesia epidural torácica (AET intra y postoperatoria sobre la presentación de taquiarritmias en el postoperatorio de las resecciones pulmonares. Material y métodos: Se han analizado, de forma retrospectiva, los cursos postoperatorios de 200 pacientes consecutivos intervenidos de resecciones pulmonares mayores (lobectomías, bilobectomías y neumonectomías en nuestro hospital durante el periodo comprendido entre octubre de 1998 y junio de 2002. En este tiempo se ha introducido progresivamente en nuestro Servicio la AET como parte de la técnica anestésica en cirugía pulmonar. Se ha analizado la influencia del empleo de AET en la presentación de episodios de taquiarritmia supraventricular en las primeras 48 horas de postoperatorio. Resultados: Se empleó AET para el manejo anestésico y control del dolor postoperatorio en el 49,5% de los casos (99/200. No existen diferencias significativas entre los grupos de pacientes con y sin AET en cuanto a edad, sexo, riesgo ASA, duración de la intervención y tipo de resecciones practicadas. Presentaron crisis de taquiarritmia el 9,5% de los pacientes (19/200, tratándose, en todos los casos, de fibrilación auricular paroxística. Entre los pacientes que no recibieron AET la tasa de arritmias fue del 13,86% (14/101, mientras que en aquellos en los que se empleó AET como parte de la técnica anestésica y durante el postoperatorio, dicha tasa fue del 5,05% (5/99, siendo dicha diferencia estadísticamente significativa (p=0,034. Conclusiones: El empleo de AET como parte de la técnica anestésica y para el manejo del dolor postoperatorio en cirugía de resección pulmonar parece ejercer un efecto protector en cuanto al desarrollo de fibrilación auricular en el postoperatorio inmediato. Se discuten las posibles causas de este efecto.Objectives: To assess the impact of intra- and post-operative thoracic epidural analgesia (TEA on the incidence of tachy

    Epidural analgesia (EA) was used in 29 patients undergoing surgical removal of lumbar discal hernia. Marcain EA with controlled medicinal sleep and non-assisted breathing allowed to perform the whole operation in 27 patients. EA may be ineffective in combination of sequestrated disk hernia with scarry adhesive process. The technique of the operation demands a single use of the anesthetic drug which is potent enough to make blockade throughout the operation up to the end.
