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

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

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

    To show the beginning of spinal and epidural anesthesia in our country and the contributions of Spanish urologists. We reviewed books and writings of History of Medicine, Urology and Anesthesia and Doctoral thesis about spinal and epidural anesthesia. In the 20th century, surgeons also gave the anesthetic drugs to the patients. Spinal and epidural anesthesia were used for the first time in 1900. A lot of Spanish urologists like F Rusca Doménech, J.M. Batrina, M. Barragán Bonet, R. Lozano Monzón, L. Guedea Calvo, Gil Vernet, Fidel Pagés Miravé, V Sagarra Lascurain, Gómez Ulla, etc, did research, writings in scientific journals and Doctoral thesis about anesthesia.

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

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

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

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

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

    The authors studied the effects of dihydroergotamine (DHE) and etilefrine hydrochloride (E) on the regional distribution of /sup 99m/Tc-marked erythrocytes during epidural anesthesia in eight supine men to determine if vasoactive agents with venoconstrictor action would enhance cardiac filling during epidural anesthesia. Radioactivity was recorded with a gamma camera, and its distribution determined in the thorax, abdomen, and limbs. Arterial and central venous pressure, heart rate, and calf volume by plethysmography were measured. During epidural anesthesia with a sensory block up to T4/5, DHE (7.5 micrograms/kg) reduced the radioactivity, i.e., blood volume, in both the innervated (-5.9 +/- 3.5%) and denervated muscle/skin (-16.9 +/- 7%) regions, and increased it in both the intrathoracic (+7.0 +/- 2.3%), and splanchnic vasculature (+4.2 +/- 3.2). In contrast, E (6 micrograms X kg-1 X min-1) decreased the blood volume most markedly in the splanchnic region (-5.4 +/- 0.7%) and increased it in the thorax (+2 +/- 0.6%). All these changes were statistically significant. The combined effects were estimated to be equivalent to a transfusion of nearly 1.01 of blood. Both drugs reversed the hypotensive action of epidural anesthesia. During epidural anesthesia, DHE preferentially constricted the capacitance vessels in skeletal muscle and skin irrespective of the state of innervation, whereas E preferentially constricted the splanchnic vasculature. In the doses used, the two agents replenished in an additive fashion the central circulation during epidural anesthesia

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

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

    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.

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

MATERIALS AND METHODS Sixty parturients (60 with severe pre-eclampsia posted for cesarean section were randomized into two groups of thirty (30 each for either spinal anesthesia that is group S or epidural anesthesia that is group E. Spinal group (group S, n=30 received 10mg (2ml of 0.5% of hyperbaric bupivacaine solution intrathecally in left lateral decubitus or sitting position at L3-4 lumbar space with 25G quincke-babcock spinal needle. Patients received 6l/min of oxygen through Hudson’s face mask throughout the surgery. In Epidural group (group E, n=30, after thorough aseptic precautions, an 18G Tuohy’s epidural needle inserted at the L3-4 lumbar space with the patient in lateral decubitus or sitting position. Three ml of 1.5% lidocaine with was given as a test dose. After ruling out any intrathecal injection of the drug, initially 8ml of 0.5% isobaric bupivacaine given and the vitals monitored. Then 3ml top-ups of the same bupivacaine solution is given in a graded manner slowly, simultaneously checking the height of block. A blockade upto T4 to T6 is required. Vitals are carefully monitored and oxygen is provided 6l/min throughout the procedure and surgery. Blood pressure (systolic, mean, diastolic, pulse rate, oxygen saturation are recorded immediately after giving anesthesia, every minute for first 10mins, then every 3mins for the rest of the surgery. Then vitals are also noted post-operatively for the first 24hrs. Apgar score after 1 and 5 minutes, of the newborn baby is also recorded. Other parameters noted were incidence and duration of hypotension or hypertension both intra-operatively and post-operatively, any usage of vasopressors (ephedrine and its dose, convulsions, renal failure, pulmonary edema, requirement for ICU stay and the number of days in the mother, and the incidence of

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

    Luiz Eduardo Imbelloni

    Full Text Available CONTEXT AND OBJECTIVES: In major orthopedic surgery of the lower limbs, continuous spinal anesthesia (CSA and combined spinal epidural anesthesia (CSE are safe and reliable anesthesia methods. In this prospective randomized clinical study, the blockading properties and side effects of CSA were compared with single interspace CSE, among patients scheduled for major hip or knee surgery. DESIGN AND SETTING: Prospective clinical study conducted at the Institute for Regional Anesthesia, Hospital de Base, São José do Rio Preto. METHODS: 240 patients scheduled for hip arthroplasty, knee arthroplasty or femoral fracture treatment were randomly assigned to receive either CSA or CSE. Blockades were performed in the lateral position at the L3-L4 interspace. Puncture success, technical difficulties, paresthesia, highest level of sensory and motor blockade, need for complementary doses of local anesthetic, degree of technical difficulties, cardiocirculatory changes and postdural puncture headache (PDPH were recorded. At the end of the surgery, the catheter was removed and cerebrospinal fluid leakage was evaluated. RESULTS: Seven patients were excluded (three CSA and four CSE. There was significantly lower incidence of paresthesia in the CSE group. The resultant sensory blockade level was significantly higher with CSE. Complete motor blockade occurred in 110 CSA patients and in 109 CSE patients. Arterial hypotension was observed significantly more often in the CSE group. PDPH was observed in two patients of each group. CONCLUSION: Our results suggest that both CSA and CSE provided good surgical conditions with low incidence of complications. The sensory blockade level and hemodynamic changes were lower with CSA.

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

    Full Text Available This study was designed to investigate the influence of saline injections as epidural top-up on the sensory block duration, quality and hemodynamic effects of unilateral spinal anesthesia. The cases from ASA I-Il containing of 18-65 age group were randomly separated into three groups. For the purpose of unilateral spinal anesthesia, 6 mg 0.5% ‘heavy’ bupivacaine and for the purpose of epidural top-up, 10 mL saline were applied to the each patients of the groups. The study protocol was designed as:Ist group: Coming after the epidural catheter installation, unilateral spinal anesthesia was applied (n=20.IInd group: At first, unilateral spinal anesthesia was applied and after one minute, epidural top-up was done via the pre-installed epidural catheter (n=20.IIIrd group: At first the epidural catheter was installed and epidural top-up was applied. After one minute, unilateral spinal anesthesia was fulfilled (n=2O. Starting from the pre-anesthesic period, the hemodynamic data and following the anesthesia, the sensorial and motor block levels were recorded and evaluated.As the outcome of the inter-groups comparison of heart rate and mean arterial pressure, a statistically note-worthy differance was not determined; statistically significant but clinically acceptable hemodynamic changes were observed in intra-group evaluations, when the data was compared with control levels. The sensorial block levels were significantly higher in group II and significantly lower in group III.The application of 10 mL saline via epidural catheter 1 minute after the unilateral spinal anesthesia and remaining the patient leaning on the side of the extremity to be operated for 15 minutes improves the sensory block level of unilateral spinal anesthesia. It is determined that, for the lower extremity surgical operations with 1-1.5 hour estimated period, this method alone can be a worthwhile alternative.

    Full Text Available Spontaneous intracranial hypotension (SIH is an important cause of new daily persistent headache. It is thought to be due to spontaneous spinal cerebrospinal fluid (CSF leaks, which probably have a multifactorial etiology. The classic manifestation of SIH is an orthostatic headache, but other neurological symptoms may be present. An epidural blood patch is thought to be the most effective treatment, but a blind infusion may be ineffective. We describe the case of a young man who developed an acute severe headache, with pain worsening when assuming an upright posture and relief gained with recumbency. No history of previous headache, recent cranial or cervical trauma, or invasive procedures was reported. Magnetic resonance imaging showed pachymeningeal enhancement and other features consistent with SIH and pointed towards a cervical CSF leak site. After failure of conservative treatment, a targeted computer tomography-guided EBP was performed, with complete recovery.

    To evaluate the impact of induced hypotensive anesthesia on length of hospital stay (LOS) for patients undergoing maxillary Le Fort I osteotomy in isolation or in combination with mandibular orthognathic surgery. A retrospective cohort study design was implemented and patients undergoing a Le Fort I osteotomy as a component of orthognathic surgery at the Mayo Clinic from 2010 through 2014 were identified. The primary predictor variable was the presence of induced hypotensive anesthesia during orthognathic surgery. Hypotensive anesthesia was defined as at least 10 consecutive minutes of a mean arterial pressure no higher than 60 mmHg documented within the anesthetic record. The primary outcome variable was LOS in hours after completion of orthognathic surgery. The secondary outcome variable was the duration of surgery in hours. Multiple covariates also abstracted included patient age, patient gender, American Society of Anesthesiologists score, complexity of surgical procedure, and volume of intraoperative fluids administered during surgery. Univariable and multivariable models were developed to evaluate associations between the primary predictor variable and covariates relative to the primary and secondary outcome variables. A total of 117 patients were identified undergoing Le Fort I orthognathic surgery in isolation or in combination with mandibular surgery. Induced hypotensive anesthesia was significantly associated with shortened LOS (odds ratio [OR] = 0.33; 95% confidence interval [CI], 0.12-0.88; P = .026) relative to patients with normotensive regimens. This association between hypotensive anesthesia and LOS remained statistically significant in a subgroup analysis of 47 patients in whom isolated Le Fort I surgery was performed (OR = 0.13; 95% CI, 0.03-0.62; P = .010). Induced hypotensive anesthesia was not statistically associated with shorter duration of surgery. Induced hypotensive anesthesia represents a potential factor that minimizes

    Full Text Available Abstract Introduction Tamsulosin, a selective α1-adrenergic receptor (α1-AR antagonist, is a widely prescribed first-line agent for benign prostatic hypertrophy (BPH. Its interaction with anesthetic agents has not been described. Case presentation We report the case of 54-year-old Asian man undergoing elective left thyroid lobectomy. The only medication the patient was taking was tamsulosin 0.4 mg for the past year for BPH. He developed persistent hypotension during the maintenance phase of anesthesia while receiving oxygen, nitrous oxide and 1% isoflurane. The hypotension could have been attributable to a possible interaction between inhalational anesthetic and tamsulosin. Conclusion Vigilance for unexpected hypotension is important in surgical patients who are treated with selective α1-AR blockers. If hypotension occurs, vasopressors that act directly on adrenergic receptors could be more effective.

    2012-11-01

    Full Text Available A 36-year-old male had spontaneous intracranial hypotension (SIH presenting with refractory headache for 4 months. Multiple epidural blood patches (EBPs yielded relief of symptoms, but the course was complicated, with asymptomatic intracranial subdural hematoma (SDH. Except for SDH, other radiological diagnostic signs of SIH were resolved and the patient’s headaches improved after EBP. Owing to a mass effect and persistent cerebrospinal fluid (CSF leakage, surgical repair of the spinal leakage was performed, but no cranial procedures were carried out. Postoperatively, the SDH completely resolved, but there was still CSF leakage at the level where surgery was performed. The patient has remained free of headache or other events for 3 years. It was reduction rather than elimination of the spinal CSF leak that yielded remission of SIH. In summary, intracranial SDH can be a complication of inadequately treated SIH (i.e. persistent minor CSF leakage. Management of SDH should focus on correction of the underlying SIH rather than craniotomy for hematoma evacuation.

    Myotonic dystrophy (MD) is a muscle disorder characterized by progressive muscle wasting and weakness, and is the most common form of muscular dystrophy that begins in adulthood, often after pregnancy. MD might be related to occurrence of malignant hyperthermia. Therefore, the cesarean section is often performed for the parturient with MD. We had an experience of combined spinal-epidural anesthesia for cesarean section in a parturient complicated with MD. A 40-year-old woman had rhabdomyolysis caused by ritodrine at 15-week gestation and was diagnosed as MD by electromyography. Her first baby died due to respiratory failure fourth day after birth. She had hatchet face, slight weakness of her lower extremities, and easy fatigability. Her manual muscle test was 5/5 at upper extremities and 4/5 at lower extremities. She underwent emergency cesarean section for premature rupture of the membrane, weak pain during labor, and obstructed labor at 33-week gestation. We placed an epidural catheter from T12/L1 and punctured arachnoid with 25 G spinal needle. We performed spinal anesthesia using 0.5% hyperbaric bupivacaine 1.5 ml and epidural anesthesia using 2% lidocaine 6 ml. Her anesthetic level reached bilaterally to T7 and operation started 18 minutes after combined spinal-epidural anesthesia. Her baby was born 23 minutes after the anesthesia. As her baby was 1/5 at Apgar score, the baby was tracheally intubated and artificially ventilated. The cesarean section was finished in 33 minutes uneventfully. She had no adverse events and was discharged on the 8th postoperative day. Later her baby was diagnosed as congenital MD by gene analysis. Combined spinal-epidural anesthesia with the amide-typed local anesthetic agents could be useful and safe for cesarean section in the parturient with MD.

    The effect of prolonged hypotensive anesthesia and surgery on renal function was studied in 8 dogs with decreased renal mass. Renal mass was reduced by unilateral nephrectomy and ligation of 4 of the 6 terminal renal artery branches of the opposite kidney. One week after reduction in renal mass, the dogs were azotemic with a serum urea nitrogen (SUN) value of 65.8 +/- 11.5 mg/dl. Glomerular filtration rate, as estimated by 14C-inulin clearance, was 0.66 +/- 0.19 ml/kg of body weight/hour. A mean arterial pressure of less than 75 mm of Hg was maintained for 4 hours in dogs given 2.3 +/- 0.7% halothane. An exploratory laparotomy lasting 1 hour was performed. The day after the hypotensive episode, 3 dogs began vomiting, became dehydrated, and had SUN values greater than 100 mg/dl. The SUN values returned to base-line values after the dogs were rehydrated. Eight days after the hypotensive episode, 14C-inulin clearance decreased 15.2 +/- 8.2% (P less than 0.005) compared with base-line clearance values. Light microscopic and electron microscopic observations of the kidneys did not demonstrate acute renal failure. Prolonged hypotensive anesthesia can cause a decrease in renal function, and may cause prerenal uremia and/or acute renal failure.

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

    Full Text Available Thoracic epidural anesthesia with ipsilateral brachial plexus block is emerging as an alternative to general anesthesia for oncologic breast surgery.1. A 31 year old, pneumonectomised female with a past history of MDR TB was diagnosed with infiltrating ductal carcinoma in left breast 2 months ago and was posted for MRM. She also had moderate Pulmonary Arterial Hypertension. Thoracic epidural anesthesia was induced with 12 ml of 0.5% Ropivacaine at T6-T7 level. Interscalene block was given with 10 ml 0.5% Ropivacaine using peripheral nerve locator. Patient was comfortable throughout the procedure and remained vitally stable. Post-operative analgesia was given with 10 ml of 0.2% ropivacaine and patient was discharged the following week. Thoracic epidural anesthesia provides the advantage of superior intra and post-operative analgesia without the adverse effects of general anesthesia like postoperative nausea, vomiting, respiratory depression and sedation.2 Coupled with interscalene block for axillary lymph node dissection, it can be successfully used as an alternative to GA for MRM.

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

    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.

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

    BACKGROUND: The purpose of this study was to determine whether anesthesia affects graft patency after lower extremity arterial in situ bypass surgery. METHODS: This investigation was a retrospective study using a national database on vascular surgical patients at a single medical institution. We...... under epidural (n = 386) or general (n = 499) anesthesia. Thirty-day mortality (3.4% for epidural anesthesia versus 4.4% general anesthesia; P = 0.414) and comorbidity were comparable in the 2 groups. Graft occlusion within 7 days after surgery was reported in 93 patients, with a similar incidence...... in the epidural (10.1%) and general (10.8%) anesthesia groups (P = 0.730). When examining a subgroup of patients (n = 242) exposed to surgery on smaller vessels (femorodistal in situ bypass procedures, n = 253), the incidence of graft occlusion was also similar in the 2 groups at 14.0% and 9.4%, respectively (P...

    The pulse oximeter perfusion index (PI) has been used to indicate sympathectomy-induced vasodilatation. We hypothesized that pulse oximeter PI provides an earlier and clearer indication of sympathectomy following epidural anesthesia than skin temperature and arterial pressure. Forty patients received lumbar epidural catheters. Patients were randomized to receive either 10 ml 0.5% bupivacaine or 10 ml 0.25% bupivacaine. PI in the toe, mean arterial pressure (MAP) and toe temperature were all assessed at baseline and at 5, 10 and 20 min following epidural anesthesia. The effect of epidural anesthesia over time was assessed by repeated measures analysis of variance. Additionally, we defined clinically evident sympathectomy criteria (a 100% increase in the PI, a 15% decrease in MAP and a 1 degrees C increase in toe temperature). The numbers of patients demonstrating these changes for each test were compared using the McNemar test for each time point. Twenty-nine subjects had photoplethysmography signals that met a priori signal quality criteria for analysis. By 20 min, PI increased by 326%, compared with a 10% decrease and a 3% increase in MAP and toe temperature, respectively. For PI 15/29, 26/29 and 29/29 of the subjects met the sympathectomy criteria at 5, 10 and 20 min, respectively, compared with 4/29, 6/29 and 18/29 for MAP changes and 3/29, 8/29 and 14/29 for toe temperature changes. PI was an earlier, clearer and more sensitive indicator of the development of epidural-induced sympathectomy than either skin temperature or MAP.

    To assess the effects of high thoracic epidural anesthesia on left ventricular (LV) diastolic filling and systolic function in patients without heart disease. Prospective study. University hospital. 24 ASA physical status I and II patients scheduled for elective noncardiac surgery. Patients received high thoracic (HTE; n = 12) or low thoracic (LTE; n = 12) epidural anesthesia. Left ventricular diastolic filling was noninvasively determined by precordial echocardiography using a pulsed Doppler technique and with a newly developed acoustic quantification (AQ) method that automatically detects endocardial borders and measures cavity area. All measurements were performed in awake premedicated patients. In the HTE group, the extent of sensory blockade of T1-T5, at the least, was induced with 2% lidocaine 5 ml. During HTE, systolic blood pressure (119 +/- 16 vs. 108 +/- 14 mmHg, p LTE group, no significant differences were noted in all systolic and diastolic indices obtained by pulsed Doppler and AQ method. High thoracic epidural anesthesia causes a decrease in CO without changing LV ejection and diastolic filling performance in healthy subjects.

    A 29-year-old woman at 34 weeks' gestation with uncontrolled hyperthyroidism and thyrotoxic heart disease was admitted to urgency Cesarean section. After preoperative sedation and good communication, low-dose spinal anesthesia (7.5 mg 0.5 % bupivacaine) combined with epidural anesthesia (6 ml 2 % lidocaine) was performed through L3-4 inter-vertebral. Opioids were given intravenously to the mother for sedation after delivery of the baby. Satisfactory anesthesia and sedation was provided during surgery. The mother and the neonate were safe and no special complication was found after surgery. Our case demonstrated that low-dose spinal anesthesia combined with epidural anesthesia with intravenous opioids can provide satisfactory anesthesia and sedation, and reduce the risk of heart failure and thyroid storm.

Of major concern to anesthesiologists is unintentional spinal block. Reliable identification of cerebrospinal fluid (CSF from the aspirate is crucial for safe epidural anesthesia. The aim of this study was to determine whether prostaglandin D2 could be clinically used as a marker for the detection of CSF traces.Methods: After obtaining Institutional Review Board approval and patient consent, CSF was obtained from patients undergoing spinal anesthesia, and blood, urine, and saliva were obtained from normal subjects and analyzed for prostaglandin D2 (PGD. CSF (n=5 samples were diluted with local anesthetic (bupivacaine, normal saline and blood in the ratios of 1:5 and 1:10. PGD levels in the CSF samples were analyzed with a PGD-Methoxime (MOX EIA Kit (Cayman Chemicals, MI. This assay is based on the conversion of PGD to a stable derivative, which is analyzed with antiserum specific for PGD-MOX. Results: Different concentrations of pure PGD-MOX conjugate were analyzed by EIA and a standard curve was derived. PGD levels in CSF and CSF with diluents were determined and the values were extrapolated onto the standard curve. Our results show a well-defined correlation for the presence of PGD both in straight CSF samples and in diluted CSF (dilution factor of 1:5 and 1:10. Conclusion: Prostaglandin D2 was reliably identified in CSF by enzyme-linked immunosorbent assay when diluted with local anesthetic, saline, and serum, and can be used as a marker to identify the presence of CSF in epidural aspirates.Keywords: epidural, cerebrospinal fluid, leak, marker, prostaglandin D2

    A prospective randomized study was executed to compare the surgical parameters and stone clearance in patients who underwent percutaneous nephrolithotomy (PNL) under combined spinal-epidural anesthesia (CSEA) versus those who underwent PNL under general anesthesia (GA). Between January 2008 to December 2009, 64 patients with renal calculi were randomized into 2 groups and evaluated for the purpose of this study. Group 1 consisted of patients who underwent PNL under CSEA and Group 2 consisted of patients who underwent PNL under GA. The operative time, stone clearance rate, visual pain analog score, mean analgesic dose and mean hospital stay were compared amongst other parameters. The difference between visual pain analog score after the operation and the dose of analgesic requirement was significant on statistical analysis between both groups. PNL under CSEA is as effective and safe as PNL under GA. Patients who undergo PNL under CESA require lesser analgesic dose and have a shorter hospital stay. Copyright © 2011 S. Karger AG, Basel.

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

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

    Intraoperative hypotension and hypertension are associated with adverse clinical outcomes and morbidity. Clinical decision support mediated through an anesthesia information management system (AIMS) has been shown to improve quality of care. We hypothesized that an AIMS-based clinical decision support system could be used to improve management of intraoperative hypotension and hypertension. A near real-time AIMS-based decision support module, Smart Anesthesia Manager (SAM), was used to detect selected scenarios contributing to hypotension and hypertension. Specifically, hypotension (systolic blood pressure 1.25 minimum alveolar concentration [MAC]) of inhaled drug and hypertension (systolic blood pressure >160 mm Hg) with concurrent phenylephrine infusion were detected, and anesthesia providers were notified via "pop-up" computer screen messages. AIMS data were retrospectively analyzed to evaluate the effect of SAM notification messages on hypotensive and hypertensive episodes. For anesthetic cases 12 months before (N = 16913) and after (N = 17132) institution of SAM messages, the median duration of hypotensive episodes with concurrent high MAC decreased with notifications (Mann Whitney rank sum test, P = 0.031). However, the reduction in the median duration of hypertensive episodes with concurrent phenylephrine infusion was not significant (P = 0.47). The frequency of prolonged episodes that lasted >6 minutes (sampling period of SAM), represented in terms of the number of cases with episodes per 100 surgical cases (or percentage occurrence), declined with notifications for both hypotension with >1.25 MAC inhaled drug episodes (δ = -0.26% [confidence interval, -0.38% to -0.11%], P 1.25 MAC inhaled drug episodes. However, since phenylephrine infusion is manually documented in an AIMS, the impact of notification messages was less pronounced in reducing episodes of hypertension with concurrent phenylephrine infusion. Automated data capture and a higher frequency of

    To study the indications, methods and experience of absorbable rib-connecting-pins fixation in the treatment of multiple rib fractures. 52 cases with multiple rib fractures were performed internal fixation with absorbable rib-connecting-pins under epidural anesthesia. All cases were followed up for 1 to 12 months, with an average of 5 months. All fractures were achieved healing in 3 to 6 months after the operation and were not found chest wall deformity. Absorbable rib-connecting-pins fixation is a simple and effective method and worthies recommending to perform operation for the appropriate cases with multiple rib fractures.

    Full Text Available Objective: The objective of the study was to compare the outcomes of the incidence of nausea/vomiting and other complications along with the time taken for discharged in patients undergoing Thoracic Epidural Analgesia (TEA and General Anaesthesia (GA for breast oncological surgeries. Background: GA with or without TEA or other postoperative pain-relieving strategies remains the traditional anesthetic technique used for breast oncological procedures. We initiated the use of high segmental TEA for patients undergoing these procedures in our hospital. Methods: Eighty patients undergoing breast oncological procedures performed by one surgical team were randomly allocated into two groups receiving TEA and GA. The Chi-square test and Fisher's exact test were used for categorical parameters, paired t-test and Student's t-test was used for continuous measurements. Results: In comparison with GA, TEA was associated with lesser incidence of complications of nausea/vomiting. In lumpectomy with axillary node dissection, 1 out of 18 patients (5.55% in the TEA group had nausea/vomiting, while 11 out of 19 (57.8% of the GA group had similar symptoms (P < 0.001. The discharge rate for the thoracic epidural group was 12 out of 18 by day 3 (66.6% while all patients in the GA group required more than 3 days of hospitalization (P < 0.001. Conclusion: Thoracic epidural anesthesia is a safe technique and its use in breast oncological procedures could improve patients' recovery and facilitate their early discharge to home.

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

    Spontaneous intracranial hypotension (SIH) is caused by single or multiple cerebrospinal fluid (CSF) leaks in the spine with the prototypical symptom of postural headache. One of the characteristic MRI features in SIH is intracranial venous engorgement. This report presents a case of SIH with engorgement of the bilateral superior ophthalmic veins (SOVs) which resume their normal diameters by the third day of successful epidural blood patches (EBPs). We define this phenomenon as the 'reversal of the SOV' sign.

    Full Text Available Background and Aims: This study was conducted to determine the effectiveness of intravenous (IV granisetron in the prevention of hypotension and bradycardia during spinal anesthesia in cesarean delivery. Material and Methods: A total of 200 parturients scheduled for elective cesarean section were included in this study. They were randomly divided into two groups. Group I was given 1 mg granisetron diluted in 10 ml normal saline slowly IV, 5 min before spinal anesthesia. Group II was given 10 ml of normal saline, 5 min before spinal anesthesia. Mean arterial blood pressure and heart rate (HR were recorded every 3 min until the end of surgery (for 45 min. The total consumption of vasopressors and atropine were recorded. Apgar scores at 1 and 5 min were also assessed. Results: Serial mean arterial blood pressure and HR values for 45 min after onset of spinal anesthesia were decreased significantly in group II, P < 0.0001. The incidence of hypotension after spinal anesthesia was 64% in group II and 3% in group I (P < 0.0001. The total doses of ephedrine (4.07 ± 3.87 mg vs 10.7 ± 8.9 mg, P < 0.0001, phenylephrine (0.0 microg vs 23.2 ± 55.1 microg, P < 0.0001, and atropine (0.0 mg vs 0.35 ± 0.49 mg P < 0.0001 consumed in both the groups respectively, were significantly less in group I versus group II. Conclusion: Premedication with 1 mg IV granisetron before spinal anesthesia in an elective cesarean section significantly reduces hypotension, bradycardia and vasopressors usage.

    Full Text Available Maternal hypotension is a common complication after spinal anesthesia for cesarean section, with deleterious effects on the fetus and mother. Among the strategies aimed at minimizing the effects of hypotension, vasopressor administration is the most efficient. The aim of this study was to compare the efficacy of phenylephrine, metaraminol, and ephedrine in the prevention and treatment of hypotension after spinal anesthesia for cesarean section. Ninety pregnant women, not in labor, undergoing cesarean section were randomized into three groups to receive a bolus followed by continuous infusion of vasopressor as follows: phenylephrine group (50 μg + 50 μg/min; metaraminol group (0.25 mg + 0.25 mg/min; ephedrine group (4 mg + 4 mg/min. Infusion dose was doubled when systolic blood pressure decreased to 80% of baseline and a bolus was given when systolic blood pressure decreased below 80%. The infusion dose was divided in half when systolic blood pressure increased to 120% and was stopped when it became higher. The incidence of hypotension, nausea and vomiting, reactive hypertension, bradycardia, tachycardia, Apgar scores, and arterial cord blood gases were assessed at the 1st and 5th minutes. There was no difference in the incidence of hypotension, bradycardia, reactive hypertension, infusion discontinuation, atropine administration or Apgar scores. Rescue boluses were higher only in the ephedrine group compared to metaraminol group. The incidence of nausea and vomiting and fetal acidosis were greater in the ephedrine group. The three drugs were effective in preventing hypotension; however, fetal effects were more frequent in the ephedrine group, although transient.

    Prophylactic treatment has been proved to reduce hypotension incidence after spinal anesthesia during cesarean labor. However, the use of pharmacological prophylaxis could carry out undesirable side-effects on mother and fetus. Thus, the prediction of hypotension becomes an important challenge. Hypotension events are hypothesized to be related to a malfunctioning of autonomic nervous system (ANS) regulation of blood pressure. In this work, ANS responses to positional changes of 51 pregnant women programmed for a cesarean labor were explored for hypotension prediction. Lateral and supine decubitus, and sitting position were considered while electrocardiographic and pulse photoplethysmographic signals were recorded. Features based on heart rate variability, pulse rate variability (PRV) and pulse transit time (PTT) analysis were used in a logistic regression classifier. The results showed that PRV irregularity changes, assessed by approximate entropy, from supine to lateral decubitus, and standard deviation of PTT in supine decubitus were found as the combination of features that achieved the best classification results sensitivity of 76%, specificity of 70% and accuracy of 72%, being normotensive the positive class. Peripheral regulation and blood pressure changes, measured by PRV and PTT analysis, could help to predict hypotension events reducing prophylactic side-effects in the low-risk population.

    Background Continuous epidural anesthesia is useful for endoscopic urologic surgery, as mostly performed in the elderly patients. In such a case, it is necessary to obtain successful sacral anesthesia, and the insertion of epidural catheter in the caudad direction may be needed. However, continuous epidural catherization has been related to paresthesias. This study aimed to evaluate the effects of the direction of the catheter insertion on the incidence of paresthesias in the elderly patients. Methods Two hundred elderly patients scheduled for endoscopic urologic surgery were enrolled. The epidural catheter was inserted at L2-3, L3-4, and L4-5 using the Tuohy needle. In Group I (n = 100), the Tuohy needle with the bevel directed the cephalad during the catheter insertion. In Group II (n = 100), it directed the caudad. During the catheter insertion, an anesthesiologist evaluated the presence of paresthesias and the ease or difficulty during the catheter insertion. Results In Group I (n = 97), 15.5% of the patients had paresthesias versus 18.4% in Group II (n = 98), and there was no significant difference between the two groups. In paresthesia depending on the insertion site and the ease or difficulty during the catheter insertion, there were no significant differences between the two groups. Conclusions Our results concluded that the direction of epidural catheter insertion did not significantly influence the incidence of paresthesias in the elderly patients. PMID:23741568

    Background Spinal anesthesia (SA) is a standard technique for cesarean section. Hypotension presents an incident of 80–85% after SA in pregnant women. Objective To determine the effect of intermittent pneumatic compression of lower limbs on declining spinal anesthesia induced hypotension during cesarean section. Methods This double-blind clinical prospective study was conducted on 76 non-laboring parturient patients, aged 18–45 years, with the American Society of Anesthesiologist physical status I or II who were scheduled for elective cesarean section at Razi Hospital, Ahvaz, Iran from December 21, 2015 to January 20, 2016. Patients were divided into treatment mechanical pump (Group M) or control group (Group C) with simple random sampling. Fetal presentation, birth weight, Apgar at 1 and 5 min, time taken for pre-hydration (min), pre-hydration to the administration of spinal anesthesia (min), initiation of spinal to the delivery (min) and total volume of intravenous fluids, total dose of ephedrine and metoclopramide were recorded. Data were analyzed by SPSS version 19, using repeated measures of ANOVA and Chi square test. Results Heart rate, MPA, DAP and SAP changes were significantly higher in off-pump group in the baseline and 1st-minute (p<0.05), and in the other times, this change was significantly different with control groups. Conclusion This research showed the suitability of the use of Sequential Compression Device (SCD) in reducing hypotension after spinal anesthesia for cesarean section, also this method can cause reducing vasopressor dosage for increased blood pressure, but the approval of its effectiveness requires repetition of the study with a larger sample size. Trial registration The trial was registered at the Iranian Registry of Clinical Trials (http://www.irct.ir) with the IRCT ID: IRCT2015011217742N3.

    There are many teaching methods for epidural anesthesia skill acquisition. Previous work suggests that there is no difference in skill acquisition whether novice learners engage in low-fidelity (LF) versus high-fidelity haptic simulation for epidural anesthesia. No study, however, has compared the effect of LF haptic simulation for epidural anesthesia versus mental imagery (MI) training in which no physical practice is attempted. We tested the hypothesis that MI training is superior to LF haptic simulation training for epidural anesthesia skill acquisition. Twenty Post-Graduate Year 2 (PGY-2) anesthesiology residents were tested at the beginning of the training year. After a didactic lecture on epidural anesthesia, they were randomized into 2 groups. Group LF had LF simulation training for epidural anesthesia using a previously described banana simulation technique. Group MI had guided, scripted MI training in which they initially were oriented to the epidural kit components and epidural anesthesia was described stepwise in detail, followed by individual mental rehearsal; no physical practice was undertaken. Each resident then individually performed epidural anesthesia on a partial-human task trainer on 3 consecutive occasions under the direct observation of skilled evaluators who were blinded to group assignment. Technical achievement was assessed with the use of a modified validated skills checklist. Scores (0-21) and duration to task completion (minutes) were recorded. A linear mixed-effects model analysis was performed to determine the differences in scores and duration between groups and over time. There was no statistical difference between the 2 groups for scores and duration to task completion. Both groups showed similarly significant increases (P = 0.0015) in scores over time (estimated mean score [SE]: group MI, 15.9 [0.55] to 17.4 [0.55] to 18.6 [0.55]; group LF, 16.2 [0.55] to 17.7 [0.55] to 18.9 [0.55]). Time to complete the procedure decreased

    Hypotensive anesthesia is crucial during arthroscopic shoulder surgery to reduce bleeding and allow for clear visibility. The aim of this study was to compare the clinical efficacy of continuous infusion of remifentanil, nicardipine, and remifentanil plus nicardipine to control hypotensive anesthesia in arthroscopic shoulder surgery. For this study, we enrolled 45 consecutive patients who were scheduled to have arthroscopic rotator cuff repair surgery and randomly allocated them into remifentanil (group R, n = 15), nicardipine (group N, n = 15), and remifentanil plus nicardipine (group RN, n = 15) groups. During the surgeries, these drugs were administered with continuous infusion. We analyzed the mean arterial pressure (MAP) and heart rate during surgery, stay time in the recovery room, visual analogue scale (VAS) scores, use of antiemetics in the recovery room, and postoperative blood urea nitrogen and creatinine changes. The VAS score in the recovery room was higher for group R (mean 5.6, SD 1.4) than for groups N (mean 3.9, SD 0.9) and RN (mean 4.0, SD 1.1; p = 0.000). There were no statistical differences regarding other clinical variables among the three groups (all p > 0.05) except for MAP at 120 min of surgery between groups N and RN (N: 84.67 (SD 10.7) mmHg, RN: 65.4 (SD 9.2) mmHg, p = 0.027). The continuous infusion of remifentanil plus nicardipine appeared to be advantageous for maintaining hypotensive anesthesia until 120 min of arthroscopic shoulder surgery without rebound pain in a postanesthesia care unit.

    Full Text Available Nandita Mehta, Sunana Gupta, Atul Sharma, Mohd Reidwan Dar Department of Anesthesiology and Intensive Care, Acharya Shri Chander College of Medical Sciences and Hospital, Jammu, Jammu and Kashmir, India Abstract: Older people undergoing any surgery have a higher incidence of morbidity and mortality, resulting from a decline in physiological reserves, associated comorbidities, polypharmacy, cognitive dysfunction, and frailty. Most of the clinical trials comparing regional versus general anesthesia in elderly have failed to establish superiority of any single technique. However, the ideal approach in elderly is to be least invasive, thus minimizing alterations in homeostasis. The goal of anesthetic management in laparoscopic procedures includes management of pneumoperitoneum, achieving an adequate level of sensory blockade without any respiratory compromise, management of shoulder tip pain, provision of adequate postoperative pain relief, and early ambulation. Regional anesthesia fulfills all the aforementioned criteria and aids in quick recovery and thus has been suggested to be a suitable alternative to general anesthesia for laparoscopic surgeries, particularly in patients who are at high risk while under general anesthesia or for patients unwilling to undergo general anesthesia. In conclusion, we report results of successful management with thoracic combined spinal epidural for laparoscopic cholecystectomy of a geriatric patient with ischemic heart disease with chronic obstructive pulmonary disease and renal insufficiency.

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

    To observe the intervention of transcutaneous electrical acupoint stimulation (TEAS) on the renal blood flow at different levels of mean arterial pressure (MAP) in controlled hypotension. Forty-two male beagle dogs were randomly divided into seven groups, i. e., the general anesthesia group, the 50% controlled group, the 40% controlled group, the 30% controlled group, the 50% experimental group, the 40% experimental group, and the 30% experimental group, 6 in each group. Beagles in the general anesthesia group were not treated with controlled hypotension, and the target MAP was achieved in those of the rest groups and maintained for 60 min. In the experimental groups, TEAS was applied to bilateral Hegu (LI4), Zusanli (ST36), Sanyinjiao (SP6), and Quchi (LI11) at 2/100 Hz with the stimulation strength of (4 +/- 1) mA starting from the stability of their physiological conditions to 60 min of maintaining the target MAP level. The changes of the renal blood flow were monitored at different time points using laser Doppler. From starting pressure control to the target MAP level, the renal blood flow was significantly lower in the 30% controlled group than in the general anesthesia group and the basic level of the same group (P blood pressure, the renal blood flow was significantly lower in the 50% controlled group, the 40% controlled group, the 30% controlled group, and the 30% experimental group than in the general anesthesia group (P blood pressure recovery, the renal blood flow restored to the basic level in the 50% controlled group, the 50% experimental group, and the 40% experimental group (P > 0.05), while it was not restored to the basic level in the 40% controlled group, the 30% controlled group, and the 30% experimental group (P renal blood flow, thus protecting the kidney.

    To compare the effectiveness of preload and coload for the prevention of Spinal Induced Hypotension (SIH) and vasopressor requirements. Study Design: Randomized trial. Place and Duration of Study: Department of Anesthesia, The Aga Khan University Hospital, Karachi, Pakistan, from June 2007 - June 2010. Methodology: Sixty patients were randomly divided into preload and coload group of 30 each. Patients with ASA1 - 3, aged 20 - 60 years were included. Patients with history of IHD, COPD, BMI > 30 and surgical procedure TURP were excluded. All patients received crystalloid 10 ml/kg before induction of spinal anesthesia in preload group and at the time of spinal anesthesia in coload group. Blood pressure and heart rate were recorded at different time intervals till 45 minutes. Patients received ephedrine 5 mg when systolic blood pressure dropped below 90 mmHg and heart rate was less than 60 beats/minute and/or phenylephrine 50 micrograms when systolic blood pressure dropped below 90 mmHg and heart rate was more than 60 beats/minute. Results: There was no statistically significant difference at different time intervals in heart rate, systolic and mean arterial pressure between the groups. Diastolic blood pressure was significantly different in both groups at 6 - 15 minutes after spinal anesthesia. SIH occurred (21) 70% and (15) 50% in preload and coload groups, respectively (p=0.187). Ephedrine requirement for SIH was significantly high in preload group (p=0.017). Phenylephrine requirement for SIH was high in preload group which was statistically non-significant (p=0.285). Conclusion: Coload group has lower incidence of spinal induced hypotension and significantly less vasopressor requirement than the preload group. (author)

    Full Text Available Due to the relatively high prevalence of hypotension (20% -40% after spinal anesthesia as well as the adverse effects of hypotension on mother and baby, it is better to prevent hypotension as much as possible. Therefore, this study is aimed to determine the relationship between postural blood pressure and heart rate changes and hypotension incidence rate after spinal anesthesia in cesarean section.63 women aging18 to 45years old with fullterm pregnancy, who were candidate for caesarean section with spinal anesthesia, entered the study. Afterwards, the diastolic, systolic, and mean arterial pressures as well as the heart rate (pulse in different positions (sitting, lying, and left lateral were measured. After spinal anesthesia, the patients' blood pressure was measured and recorded every minute until the10thmin, then every 3 minute until the15thmin, and then every 5 minute until the end of cesarean section. Data analysis was performed using SPSS (ver. 19 software, descriptive statistics, one-way ANOVA, and post hoc Bonferroni test. In this study, the hypotension incidence rate was 30% and the orthostatic variation rate of the systolic blood pressure in more than half of the people was between 4.39 to 13.49psi, which showed the highest variation compared to the diastolic pressure, mean arterial blood pressure (or: mean arterial pressure [MAP], and heart(pulse. Considering the correlation coefficient of 0.27, the systolic blood pressure in the lateral position has the highest relationship with the incidence of hypotension. The postural systolic blood pressure changes in patients prior to the spinal anesthesia can be a predictive factor for the post-spinal hypotension incidence.

    Multiple trials have been tried to prevent hypotension during spinal anesthesia. However, the drug choice and mode of administration is still a matter of debate. To compare the outcome of spinal injection of hyperbaric bupivacaine and fentanyl separately to standard injection of mixed fentanyl with hyperbaric bupivacaine. A randomized, controlled clinical trial. One hundred twenty-four parturient scheduled for elective cesarean section were randomly allocated into two groups, each 62 parturient: Group M received spinal anesthesia using 10 mg bupivacaine 0.5% premixed with 25 μg fentanyl in the same syringe and Group S received 25 μg fentanyl in one syringe and 10 mg bupivacaine 0.5% without barbotage in a second syringe. Patients with intraoperative pain that was controllable without the need for a shift to general anesthesia was significantly lower in Group S (3.2%) than in Group M (16.1%). The frequency of hypotension was significantly lower in Group S compared to Group M (P 0.05). There was no significant difference in the time till occurrence of hypotension, duration of hypotension, mean dose of ephedrine used for the treatment of hypotension and frequency of patients developed itching between the groups (P > 0.05). Separate intrathecal injection of fentanyl and hyperbaric bupivacaine provided a significant improvement in the quality of sensory block and significant reduction of the frequency of hypotension compared to injection of mixed medications.

    PurposeTo evaluate a modified superior hypogastric nerve block (SHNB) to reduce pain after uterine artery embolization (UAE) compared to epidural anesthesia.Materials and methodsIn this retrospective study, the amount of opiate drugs needed after UAE was compared between SHNB and epidural anesthesia. Eighty one consecutive women (mean age: 43.67 years) were in the SHNB group and 27 consecutive women (mean age: 43.48 years) treated earlier at the same institution in the epidural anesthesia group. UAE was performed from a unilateral femoral artery approach using a 4F catheter. 500–700 or 700–900 μm trisacryl gelatine microspheres were used as embolic agents. The SHNB was performed by advancing a 21G from the abdominal wall below the umbilicus to the anterior portion of the 5th vertebral body. For optimal guidance a cranio-caudal tilt of 5°–15° was used. On a lateral view the correct contrast distribution in front of the vertebral body is confirmed. Then 20 ml local anesthesia (ropivacain 0.75 %) is injected. In case of an asymmetric right–left distribution the needle was repositioned.ResultsAll SHNB were successful without severe complications. The mean time for the SHNB was 4 min 38 s (2 min 38 s–9 min 27 s). The needle was repositioned in average 0.87 times. The opiate dose for the SHNB group was 19.33 ± 22.17 mg which was significantly lower. The average time to receive an opiate drug after SHNB was 4 h 41 min.ConclusionThe SHNB is a safe and minimally time-consuming way to reduce pain after UAE especially within the first 4 h

    The paper describes cranial nerve damage, a rare complication of neuroaxial anesthesia in obstetric care. In the literature, there are summarized data on 17 cases of neurological deficit developing after subarachnoidal or epidural anesthesia in puerperas. The etiological and pathogenetic factors of the above complications may be suggested to be the high disposition of a local anesthetic, arterial hypotension due to neuroaxial anesthetics, the outflow of cerebrospinal fluid after pachymeningeal puncture (including after unintended puncture during epidural anesthesia), and ischemic injury after the blood packing performed to relieve postpuncture headache. Closer consideration of these risk factors seems to reduce the incidence of cranial nerve damage in puerperas.

    Novel therapies aimed at modulating the autonomic nervous system, including thoracic epidural anesthesia (TEA), have been shown in small case series to be beneficial in treating medically refractory ventricular tachycardia (VT) storm. However, it is not clear when these options should be considered. We reviewed a multicenter experience with TEA in the management of VT storm to determine its optimal therapeutic use. Data for 11 patients in whom TEA was instituted for VT storm between July 2005 and March 2016 were reviewed to determine the clinical characteristics, outcomes, and role in management. The clinical presentation was incessant VT in 7 (64%), with polymorphic VT in 3 (27%) and monomorphic VT in 8 (73%). The underlying conditions were nonischemic cardiomyopathy in 5 (45%), ischemic cardiomyopathy in 3 (27%), and hypertrophic cardiomyopathy, Brugada syndrome, and cardiac lipoma in 1 (9%) each. Five (45%) had a complete and 1 (9%) had a partial response to TEA; 4 of the complete responders had incessant VT. All 4 patients with a documented response to deep sedation demonstrated a complete response to TEA. More than half of the patients with VT storm in our series responded to TEA. TEA may be effective and should be considered as a therapeutic option in patients with VT storm, especially incessant VT, who are refractory to initial management. Improvement in VT burden with deep sedation may suggest that sympathoexcitation plays a key role in perpetuating VT and predict a positive response to TEA. © 2017 The Authors.

    Older people undergoing any surgery have a higher incidence of morbidity and mortality, resulting from a decline in physiological reserves, associated comorbidities, polypharmacy, cognitive dysfunction, and frailty. Most of the clinical trials comparing regional versus general anesthesia in elderly have failed to establish superiority of any single technique. However, the ideal approach in elderly is to be least invasive, thus minimizing alterations in homeostasis. The goal of anesthetic management in laparoscopic procedures includes management of pneumoperitoneum, achieving an adequate level of sensory blockade without any respiratory compromise, management of shoulder tip pain, provision of adequate postoperative pain relief, and early ambulation. Regional anesthesia fulfills all the aforementioned criteria and aids in quick recovery and thus has been suggested to be a suitable alternative to general anesthesia for laparoscopic surgeries, particularly in patients who are at high risk while under general anesthesia or for patients unwilling to undergo general anesthesia. In conclusion, we report results of successful management with thoracic combined spinal epidural for laparoscopic cholecystectomy of a geriatric patient with ischemic heart disease with chronic obstructive pulmonary disease and renal insufficiency.

    Lower limb orthopedic operations are frequently performed under regional anesthesia, which allows avoidance of potential side effects and complications of general anesthesia and sedation. Often though, patients feel anxious about being awake during operations. To decrease intraoperative anxiety, we use multimedia equipment consisting of a tablet device, noise-canceling headphones, and a makeshift frame, where patients can listen to music, watch movies, or occupy themselves in numerous ways. These techniques have been extensively studies in minimally invasive, short, or minor procedures but not in prolonged orthoplastic operations. We report 2 cases where audiovisual distraction was successfully applied to 9.5-hour procedures, proved to be a very useful adjunct to epidural anesthesia + sedation, and made an important contribution to positive patients' outcomes and overall patients' experience with regional anesthesia for complex limb reconstructive surgery. In the era when not only patients' safety and clinical outcomes but also patients' positive experiences are of paramount importance, audiovisual distraction may provide a simple tool to help improve experience of appropriately informed patients undergoing suitable procedures under regional anesthesia. The anesthetic technique received a very positive appraisal by both patients and encouraged us to study further the impact of modern audiovisual technology on anxiolysis for major surgery under regional anesthesia. The duration of surgery per se is not a contraindication to the use of audiovisual distraction. The absolute proviso of successful application of this technique to major surgery is effective regional anesthesia and good teamwork between the clinicians and the patients.

    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.

    To determine if the use of delayed pushing after the onset of the second stage of labor decreases the time of active pushing and decreases maternal fatigue. Randomized clinical trial. Labor and delivery unit of a not-for-profit community hospital. Convenience sample of nulliparous laboring women with epidural anesthesia. Immediate or delayed pushing (2 hours) during the second stage of labor at the time of complete cervical dilatation. The length of pushing, total length of the second stage, and maternal fatigue. A total of 77 women were studied (immediate pushing group=39; delayed pushing=38). The immediate pushing group averaged 94 (± 57) minutes in active pushing, while the delayed pushing group averaged 68 (± 46) minutes, a statistically significant difference (p=.04). No significant differences were found in fatigue scores between the immediate and delayed pushing groups (p>.05). We found that by delaying the onset of active pushing for 2 hours after the beginning of the second stage of labor, the time that nulliparous women with epidural anesthesia spent in active pushing was significantly decreased by 27%. Although the delayed pushing group rested for up to 2 hours, the total time in the second stage of labor averaged only 59 minutes longer than the immediate pushing group. © 2010 AWHONN, the Association of Women's Health, Obstetric and Neonatal Nurses.

    To determine the effects of burdizzo castration alone or in combination with ketoprofen (K), local anesthesia (LA), or caudal epidural anesthesia (EPI) on plasma cortisol, acute-phase proteins, interferon-gamma production, growth, and behavior of beef cattle, 50 Holstein x Friesian bulls (13 mo old, 307 +/- 5.3 kg) were assigned to (n = 10/treatment): 1) control (handled; C); 2) burdizzo castration (B); 3) B following K (3 mg/ kg of BW i.v.; BK); 4) B following LA (8 mL into each testis and 3 mL s.c. along the line where the jaws of the burdizzo were applied with 2% lidocaine HCl; BLA); and 5) B following EPI (0.05 mg/kg of BW of xylazine HCl and 0.4 mg/kg of BW of lidocaine HCl as caudal epidural; BEPI). The area under the cortisol curve against time was lower (P castration groups than in C. On d 7, haptoglobin and fibrinogen concentrations remained higher (P castration increased plasma cortisol and acute-phase proteins, and suppressed immune function and growth rates. Local anesthesia prolonged the increase in acute-phase proteins. Ketoprofen was more effective than LA or EPI in decreasing cortisol and partially reversed the reduction in ADG following castration. The use of K or EPI was more effective than LA in decreasing pain-associated behavioral responses observed during the first 6 h after treatment. Systemic analgesia with ketoprofen, a non-steroidal antiinflammatory drug, was more effective in reducing inflammatory responses associated with castration than LA or EPI.

    The ligamentum flavum (LF) forms the anatomic basis for the loss-of-resistance technique essential to the performance of epidural anesthesia. However, the LF presents considerable interindividual variability, including the possibility of midline gaps, which may influence the performance of epidural anesthesia. We devise a method to reconstruct the anatomy of the digitally LF based on magnetic resonance images to clarify the exact limits and edges of LF and its different thickness, depending on the area examined, while avoiding destructive methods, as well as the dissection processes. Anatomic cadaveric cross sections enabled us to visually check the definition of the edges along the entire LF and compare them using 3D image reconstruction methods. Reconstruction was performed in images obtained from 7 patients. Images from 1 patient were used as a basis for the 3D spinal anatomy tool. In parallel, axial cuts, 2 to 3 cm thick, were performed in lumbar spines of 4 frozen cadavers. This technique allowed us to identify the entire ligament and its exact limits, while avoiding alterations resulting from cutting processes or from preparation methods. The LF extended between the laminas of adjacent vertebrae at all vertebral levels of the patients examined, but midline gaps are regularly encountered. These anatomical variants were reproduced in a 3D portable document format. The major anatomical features of the LF were reproduced in the 3D model. Details of its structure and variations of thickness in successive sagittal and axial slides could be visualized. Gaps within LF previously studied in cadavers have been identified in our interactive 3D model, which may help to understand their nature, as well as possible implications for epidural techniques.

We report here a case of ultrasound-guided epidural anesthesia in combination with low-dose ketamine during cesarean delivery on a parturient with severe malformations of the skeletal system and airway problems. The ultrasound-guided epidural anesthesia was performed in the L1–L2 space, followed by an intravenous administration of ketamine (0.5 mg/kg for sedation and analgesia. Satisfactory anesthesia was provided to the patient and spontaneous ventilation was maintained during the surgery. The mother and the baby were discharged 5 days after surgery, no complications were reported for either of them. Our work demonstrated that an ultrasound-guided epidural anesthesia combined with low-dose ketamine can be used to successfully maintain spontaneous ventilation and provide effective analgesia during surgery and reduce the risk of postoperative anesthesia-related pulmonary infection.

    Hypotension should be vigilantly prevented in patients with spinal cord injury. Recent advances in neurological, intraoperative monitoring techniques have allowed Certified Registered Nurse Anesthetists to assess the effects of spinal cord ischemia and compression as they occur. This case report describes a young, healthy man who sustained a cervical spine fracture and was scheduled for anterior spinal fusion with somatosensory and motor-evoked potential (MEP) monitoring while under total intravenous anesthesia. This patient experienced a brief period of intraoperative hypotension with evidence of abnormal MEPs. A wake-up test was performed, which showed normal functioning, and the case resumed an uneventful course. Although this scenario resulted in no neurological sequelae, the effects of spinal cord ischemia due to hypotension can lead to permanent, devastating motor and sensory damage.

    esthetic breast surgeries but reports of its use in mastectomies with axillary exploration are very rare. The present study compared this technique with general anesthesia in oncologic surgeries of the breasts. METHODS: Forty patients were divided in two groups. The epidural group (n = 20 underwent epidural thoracic block with bupivacaine and fentanyl associated with sedation with midazolam. The other group (n = 20 underwent conventional general anesthesia with propofol, atracurium, and fentanyl, and maintenance with O2 and isoflurane. Duration of the surgery, the need for intraoperative complementation of anesthesia or sedation, and intraoperative hemodynamic parameters were recorded. In the postoperative period, length of time until discharge from the recovery room and from the hospital, severity of pain, analgesic consumption, adverse effects, and satisfaction with the anesthetic techniques were recorded. RESULTS: Both groups were similar and differences in the duration of the surgery were not observed. Complementary sedation was necessary in 100% of the patients who underwent epidural block and complementary sedation with infiltration of local anesthetic in the axilla in 15% of the patients in this group. The rate of hypertension was more frequent in the group of patients who underwent general anesthesia, while hypotension was more frequent in the epidural group. Pruritus was observed in 55% of the patients in the epidural group. Nausea (30% and vomiting (45% were more frequent in the general anesthesia group. The quality of postoperative analgesia was better in the epidural group, which also presented lower consumption of analgesics; the length hospitalization in this group was also lower. CONCLUSIONS: Epidural block has some advantages when compared with general anesthesia and can be considered an anesthesia option in oncologic mastectomies with axillary lymph node dissection.

Between August 2012 and September 2013, 16 patients (12 with PDPH, 4 with SIH; 5 males, 11 females; age range 19-58 years, mean age 32.8 years) who underwent EBP in the Department of Radiology were included in this study. Pain relief within three days after EBP was evaluated based on medical record and classified on a 3-level scale: complete relief; incomplete relief; and failure. Recurrence is defined as aggravated postural headache after three days. We evaluated and compared treatment outcome between PDPH and SIH, using Fisher's exact test (considered as significant when p < 0.05). In 12 PDPH patients, the EBP provided complete relief in 5 patients (41.7%), and incomplete relief in 7 patients (58.3%). In 4 SIH patients, the EBP provided complete relief in 1 patient (25%), and incomplete relief in 3 patients (75%). There was no significant difference (p = 0.511) of pain relief rate between PDPH and SIH. There was recurrence in 5 patients with PDPH and 1 patient with SIH. Five PDPH patients were retreated by EBP with incomplete relief. Fluoroscopy-guided EBP provides effective treatment of postural headache for both SIH and PDPH patients.

    The objective of this study was to evaluate the efficacy of hypotensive anesthesia in reducing intraoperative blood loss, decreasing operation time, and improving the quality of the surgical field during orthognathic surgery. A systematic review and meta-analysis of randomized controlled trials addressing these issues were carried out. An electronic database search was performed. The risk of bias was evaluated with the Jadad Scale and Delphi List. The inverse variance statistical method and a random-effects model were used. Ten randomized controlled trials were included for analysis. Our meta-analysis indicated that hypotensive anesthesia reduced intraoperative blood loss by a mean of about 169 mL. Hypotensive anesthesia was not shown to reduce the operation time for orthognathic surgery, but it did improve the quality of the surgical field. Subgroup analysis indicated that for blood loss in double-jaw surgery, the weighted mean difference favored the hypotensive group, with a reduction in blood loss of 175 mL, but no statistically significant reduction in blood loss was found for anterior maxillary osteotomy. If local anesthesia with epinephrine was used in conjunction with hypotensive anesthesia, the reduction in intraoperative blood loss was increased to 254.93 mL. Hypotensive anesthesia was effective in reducing blood loss and improving the quality of the surgical field, but it did not reduce the operation time for orthognathic surgery. The use of local anesthesia in conjunction with hypotensive general anesthesia further reduced the amount of intraoperative blood loss for orthognathic surgery.

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

    The aim of this study was to compare thoracoscopic surgery for spontaneous pneumothorax under epidural and/or local anesthesia (ELA) with that under general anesthesia and prove the feasibility and safety of thoracoscopic surgery under ELA for spontaneous pneumothorax. Relevant studies were searched in five databases from their date of publication to June 2016. We collected and analyzed the data concerning operative time, hospital stay, complications, air leak, recurrence and perioperative mortality. A forest plot was performed to compare the differences between the two groups. There were no significant differences between the ELA group and the general anesthesia (GA) group in operative time, hospital stay, complications, air leak or recurrence. There were 6 deaths reported in two studies. However, patients in the ELA group had significantly shorter global operating room time. Our study demonstrated that ELA, in comparison with GA, is feasible and safe for thoracoscopic surgery of spontaneous pneumothorax.

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

  19. Continuous spinal anesthesia.

    Continuous spinal anesthesia (CSA) is an underutilized technique in modern anesthesia practice. Compared with other techniques of neuraxial anesthesia, CSA allows incremental dosing of an intrathecal local anesthetic for an indefinite duration, whereas traditional single-shot spinal anesthesia usually involves larger doses, a finite, unpredictable duration, and greater potential for detrimental hemodynamic effects including hypotension, and epidural anesthesia via a catheter may produce lesser motor block and suboptimal anesthesia in sacral nerve root distributions. This review compares CSA with other anesthetic techniques and also describes the history of CSA, its clinical applications, concerns regarding neurotoxicity, and other pharmacologic implications of its use. CSA has seen a waxing and waning of its popularity in clinical practice since its initial description in 1907. After case reports of cauda equina syndrome were reported with the use of spinal microcatheters for CSA, these microcatheters were withdrawn from clinical practice in the United States but continued to be used in Europe with no further neurologic sequelae. Because only large-bore catheters may be used in the United States, CSA is usually reserved for elderly patients out of concern for the risk of postdural puncture headache in younger patients. However, even in younger patients, sometimes the unique clinical benefits and hemodynamic stability involved in CSA outweigh concerns regarding postdural puncture headache. Clinical scenarios in which CSA may be of particular benefit include patients with severe aortic stenosis undergoing lower extremity surgery and obstetric patients with complex heart disease. CSA is an underutilized technique in modern anesthesia practice. Perhaps more accurately termed fractional spinal anesthesia, CSA involves intermittent dosing of local anesthetic solution via an intrathecal catheter. Where traditional spinal anesthesia involves a single injection with a

    Laparoscopic cholecystectomy (LC) is usually performed under general anesthesia. Recently, laparoscopic cholecystectomy under regional anesthesia has become popular, but this creates a serious risk of thromboembolism because of pneumoperitoneum, anesthesia technique, operative positioning, and patient-specific risk factors. This randomized controlled trial compares the effects of two different anesthesia techniques in laparoscopic cholecystectomy on coagulation and fibrinolysis. This randomized prospective study included 60 low-risk patients with deep vein thrombosis (DVT) who underwent elective LC without thrombo-emboli prophylaxis. The patients were randomly divided into two groups according to the anesthesia technique: the general anesthesia (group 1, n = 30) and spinal epidural anesthesia (group 2, n = 30) groups. Measurement of the prothrombin time (PT), thrombin time (TT), international normalized ratio (INR), activated partial thromboplastin time (aPTT), and blood levels of D-dimer (DD) and fibrinogen (F) were recorded preoperatively (pre), at the first hour (post 1) and 24 h (post 24) after the surgery. These results were compared both between and within the groups. The mean age was 51.5 ±16.7 years (range: 19-79 years). Pneumoperitoneum time was similar between group 1 (33.8 ±7.8) and group 2 (34.8 ±10.4). The TT levels significantly declined postoperatively in both groups. The levels of PT, aPTT, INR, D-dimer and fibrinogen dramatically increased postoperatively in both groups. While there was not any DVT, there was a significant decline in TT. There was a dramatic rise in the PT, INR, D-dimer, fibrin degradation products (FDP), and fibrinogen following LC. This may be attributed to the effects of pneumoperitoneum and anesthesia techniques on portal vein flow.

    Purpose: To investigate the psychological consequences of high-dose-rate brachytherapy with 2 fractions in 1 application under spinal/epidural anesthesia in the treatment of locally advanced cervical cancer. Methods and Materials: In 50 patients with locally advanced cervical cancer, validated questionnaires were used for prospective assessment of acute and posttraumatic stress disorder (ASD/PTSD) (Impact of Event Scale–Revision), anxiety/depression (Hospital Anxiety and Depression Scale), quality of life (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30/Cervical Cancer 24), physical functioning (World Health Organization performance status), and pain (visual analogue scale), before and during treatment and 1 week and 3 months after treatment. Qualitative interviews were recorded in open format for content analysis. Results: Symptoms of ASD occurred in 30% of patients 1 week after treatment; and of PTSD in 41% 3 months after treatment in association with this specific brachytherapy procedure. Pretreatment predictive variables explain 82% of the variance of PTSD symptoms. Helpful experiences were the support of the treatment team, psychological support, and a positive attitude. Stressful factors were pain, organizational problems during treatment, and immobility between brachytherapy fractions. Conclusions: The specific brachytherapy procedure, as performed in the investigated mono-institutional setting with 2 fractions in 1 application under spinal/epidural anesthesia, bears a considerable risk of traumatization. The source of stress seems to be not the brachytherapy application itself but the maintenance of the applicator under epidural anesthesia in the time between fractions. Patients at risk may be identified before treatment, to offer targeted psycho-social support. The patients' open reports regarding helpful experiences are an encouraging feedback for the treatment team; the reported stressful

    Sevoflurane, an inhalational hypotensive anesthetic agent with a vasodilatory property, has been commonly used as a single agent to induce hypotension and effectively decrease blood loss in orthognathic surgery. However, it is common for patients to receive other hypotensive anesthetic agents in combination with sevoflurane. The purpose of our retrospective cohort study is to investigate whether administering an additional hypotensive agent has greater effect at reducing mean arterial pressure (MAP), estimated blood loss (EBL) and surgery time during orthognathic surgery. 57 subjects, aged 0-89 of both genders, who underwent orthognathic surgery were investigated in this study. Each patient's anesthesia records were reviewed to record the following variables of interest: EBL, duration of surgery, and MAP reduction in %. 41 subjects were placed in Group I and they received sevoflurane alone. 16 subjects were placed in Group II and they received sevoflurane plus a "supportive" agent. These "supportive" agents were esmolol, labetalol, metoprolol, nicardipine, and dexmedetomidine. The significant differences between two groups were assessed by using ANCOVA and p surgery time. Subjects in Group II experienced a greater reduction in MAP during surgery than subjects in Group I, 27.30% and 20.44%, respectively (p = 0.027). There was no significant difference for sex (p = 0.417) or age group (p = 0.113) in estimated blood loss, however. The mean surgery time in Group I was 1.93, 2.77, and 4.54 h with respect to LeFort, BSSO/IVRO, and double jaw surgery. Patients in Group II had a mean surgery time of 1.73, 2.07, and 5.64 h with respect to LeFort, BSSO/IVRO, and double jaw surgery. No statistically significant difference was demonstrated in surgery time between Group I vs. Group II (p > 0.05). Subjects in Group II experienced, on average, more blood loss than subjects in Group I, 355.50 ml and 238.90 ml, respectively. The use of multi-drug combination may offer

    Patients undergoing surgery in the beach chair position (BCP) are at a risk of cerebral ischemia. We evaluated the effect of arginine vasopressin (AVP) on hemodynamics and cerebral oxygenation during surgery in the BCP. Thirty patients undergoing shoulder surgery in BCP under propofol-remifentanil anesthesia were randomly allocated either to receive IV AVP 0.07 U/kg (AVP group, N = 15) or an equal volume of saline (control group, N = 15) 2 minutes before taking BCP. Mean arterial blood pressure (MAP), heart rate (HR), jugular venous bulb oxygen saturation (SjvO2), and regional cerebral tissue oxygen saturation (SctO2) were measured after induction of anesthesia and before (presitting in supine position) and after patients took BCP. AVP itself given before the positioning increased MAP and decreased SjvO2 and SctO2 (P 20% SctO2 decrease from presitting value) (80% vs 13%; P = 0.0003) was higher in the AVP group. The incidence of jugular desaturation (SjvO2 shoulder surgery under general anesthesia. However, it was associated with regional cerebral but not jugular venous oxygen desaturation on upright positioning.

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

    proporcionado un rápido e inmediato alivio del dolor. Estudios clínicos con mayor número de casos son necesarios para evaluar diferencia en la incidencia de cesarianas.BACKGROUND AND OBJECTIVES: Pain relief during labor is a permanent concern, aiming at the maternal well being, decreasing the stress secondary to pain, and reducing its consequences on the fetus. Several analgesia techniques can be used during labor. The aim of this study was to compare continuous and combined epidural analgesia, both of them using 0.25% bupivacaine with 50% enantiomeric excess and fentanyl. METHODS: Forty pregnant women, in labor, with cervical dilation between 4 and 5 cm, were randomly divided in two groups. Group I received continuous epidural anesthesia. Group II received combined anesthesia. The following parameters were evaluated: anthropometric measurements, gestational age, cervical dilation, length of time between the blockade and absence of pain according to the visual analogic scale, ability to walk, length of time between analgesia and complete cervical dilation, duration of the expulsive phase, maternal hemodynamic parameters, and vitality of the newborn. Possible complications, such as respiratory depression, maternal hypotension, pruritus, nausea, and vomiting were also evaluated. The Student t test was used to compare the means and the Chi-square test was used to compare the number of pregnancies and type of labor. RESULTS: There were no statistically significant differences between both groups regarding the length of time between the beginning of analgesia and complete cervical dilation, as well as regarding the duration of the expulsive phase, incidence of cesarean section related to the analgesia, maternal hemodynamic parameters, and vitality of the newborn. CONCLUSIONS: Both techniques are effective and safe for labor analgesia, although the combined technique provided fast and immediate pain relief. Clinical studies with a larger number of patients are necessary to

    2011-01-01

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

    Epidemiology is not only rare but an important cause of new daily persistent headaches among young & middle age individuals. The Etiology & Pathogenesis is generally caused by spinal CSF leak. Precise cause remains largely unknown, underlying structural weakness of spinal meninges is suspected. There are several MR Signs of Intracranial Hypotension that include:- diffuse pachymeningeal (dural) enhancement; bilateral subdural, effusion/hematomas; Downward displacement of brain; enlargement of pituitary gland; Engorgement of dural venous sinuses; prominence of spinal epidural venous plexus and Venous sinus thrombosis & isolated cortical vein thrombosis. The sum of volumes of intracranial blood, CSF & cerebral tissue must remain constant in an intact cranium. Treatment in Many cases can be resolved spontaneously or by use Conservative approach that include bed rest, oral hydration, caffeine intake and use of abdominal binder. Imaging Modalities for Detection of CSF leakage include CT myelography, Radioisotope cisternography, MR myelography, MR imaging and Intrathecal Gd-enhanced MR

    Although blood pressure (BP) monitoring is a recommended standard of care by the ASA, and pediatric anesthesiologists routinely monitor the BP of their patients and when appropriate treat deviations from 'normal', there is no robust definition of hypotension in any of the pediatric anesthesia texts or journals. Consequently, what constitutes hypotension in pediatric anesthesia is currently unknown. We designed a questionnaire-based survey of pediatric anesthesiologists to determine the BP ranges and thresholds used to define intraoperative hypotension (IOH). Members of the Society of Pediatric Anesthesia (SPA) and the Association of Paediatric Anaesthetists (APA) of Great Britain and Ireland were contacted through e-mail to participate in this survey. We asked a few demographic questions and five questions about specific definitions of hypotension for different age groups of patients undergoing inguinal herniorraphy, a common pediatric surgical procedure. The overall response rate was 56% (483/860), of which 76% were SPA members. Majority of the respondents (72%) work in academic institutions, while 8.9% work in institutions with fewer than 1000 annual pediatric surgical caseload. About 76% of respondents indicated that a 20-30% reduction in baseline systolic blood pressure (SBP) indicates significant hypotension in children under anesthesia. Most responders (86.7%) indicated that they use mean arterial pressure or SBP (72%) to define IOH. The mean SBP values for hypotension quoted by SPA members was about 5-7% lower across all pediatric age groups compared to values quoted by APA members (P = 0.001 for all age groups). There is great variability in the BP parameters used and the threshold used for defining and treating IOH among pediatric anesthesiologists. The majority of respondents considered a 20-30% reduction from baseline in SBP as indicative of significant hypotension. Lack of a consensus definition for a common clinical condition like IOH could have

    parameters were: puncture success, highest level of anesthesia, lower limb motor block, quality of anesthesia, need for additional doses, failures incidence, paresthesia, post-dural puncture headache, cardiovascular changes, mental confusion and delirium, blood transfusion and mortality. RESULTS: There were no significant differences among groups regarding gender, age, weight and height. Group 2 patients were shorter as compared to groups 1 and 3. Mean bupivacaine doses were: 15.30 mg in group 1, 23.68 mg in group 2 and 10.1 mg in group 3. They showed statistical significant differences between groups (p < 0.01. There were significant differences (p < 0.01 in cephalad dispersion between groups 1 and 2, 1 and 3 and 2 and 3, being lower with continuous spinal and higher with combined spinal-epidural anesthesia. All patients presented total motor block (Bromage score = 3. There were no significant differences in arterial hypotension, bradycardia, paresthesia and blood transfusion. Postoperative mental confusion was observed in 19 patients, with no difference between techniques. There was no difference in mortality in the first postoperative week and in the first postoperative month. CONCLUSIONS: Retrospective studies usually less and demand less time as compared to controlled studies. This retrospective study has shown that regional anesthesia techniques are related to a low mortality rate in the first postoperative month and to a low incidence of complications.

    .5, F5 e F7. The preanaesthetic medication was intravenous acepromazine (0.05mg kg-1. An intravenous bolus of fentanyl (2.5mg kg-1 was administered immediately before epidural injection. Heart and respiratory rates, electrocardiography, systolic arterial blood pressure, rectal temperature, arterial blood gases, onset time, duration of anesthesia and sensitive block level were investigated. There was decrease of heart rate after epidural injection when compared with the baseline values in F2.5, F5 and F7 treatments. Heart rate was higher in L when compared with F5 and F7 at 30 and 60 minutes after epidural anesthesia. Onset time was not statically different among the treatments. Duration of anesthesia was longer in F5 when compared with the other treatments. Sensitive block until the sixth lumbar vertebra occurred in four dogs in L. Sensitive block until the first lumbar vertebra occurred in five dogs in F2.5 and F7 and in six dogs in F5. In conclusion, the addition of fentanyl to lidocaine in epidural anesthesia allowed cranial sensory block in relation to the isolated use of lidocaine. The addition of fentanyl (5mg kg-1 to lidocaine prolonged the anesthetic blockade when compared with others treatments.

    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.

    Laparoscopic surgery is normally performed under general anesthesia, but regional techniques like thoracic epidural and lumbar spinal have been emerging and found beneficial. We performed a clinical case study of segmental thoracic spinal anaesthesia in a healthy patient. We selected an ASA grade I patient undergoing elective laparoscopic cholecystectomy and gave spinal anesthetic in T10-11 interspace using 1 ml of bupivacaine 5 mg ml -1 mixed with 0.5 ml of fentanyl 50 μg ml -1 . Other drugs were only given (systemically) to manage patient anxiety, pain, nausea, hypotension, or pruritus during or after surgery. The patient was reviewed 2 days postoperatively in ward. The thoracic spinal anesthetia was performed easily in the patient. Some discomfort which was readily treated with 1mg midazolam and 20 mg ketamine intravenously. There was no neurological deficit and hemodynamic parameters were in normal range intra and post-operatively and recovery was uneventful. We used a narrow gauze (26G) spinal needle which minimized the trauma to the patient and the chances of PDPH, which was more if 16 or 18G epidural needle had been used and could have increased further if there have been accidental dura puncture. Also using spinal anesthesia was economical although it should be done cautiously as we are giving spinal anesthesia above the level of termination of spinal cord.

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

    Objective was to investigate the effect of sevoflurane anesthesia on heart rate (HR) fall with the injection of the initial drug in caudal space to confirm the correct needle placement. After the ethical approval was obtained from the hospital's ethics committee, a prospective randomized, clinical study was designed in Yeditepe University Hospital, in 2007. Children aged 1-12 years, scheduled for infraumblical surgery under general anesthesia and caudal block were included in the study. Anesthesia was induced and maintained by sevoflurane in group S (n=8) and by halothane in group H (n=82). Baseline HR was recorded before the caudal block was performed. The HR changes during the initial dose and total drug injection was recorded followed by 2 more HR recordings taken 5 and 10 minutes after caudal injection. The success of the block was recorded by a blind observer. There were 167 children included in the study. Caudal block success was 96.5% in group S and 97.6% in group H. Basal HR was 110.9+-10.9 in group S and 105.9+-10.1 in group H. Following the initial drug injection, mean HR was 109.8+-10.9 in group S and 102.9+-9.9 in group H. It was significantly lower than the baseline in group. The only significant decrease in the HR of the patients in group S was at the tenth minute following caudal injection. The decrease in HR with drug injection has no value to predict the success of caudal block under sevoflurane anesthesia. (author)

    Purpose Previous lumbar spinal surgery (PLSS) is not currently considered as a contraindication for regional anesthesia. However, there are still problems that make spinal anesthesia more difficult with a possibility of worsening the patient's back pain. Spinal anesthesia using combined spinal-epidural anesthesia (CSEA) in elderly patients with or without PLSS was investigated and the anesthetic characteristics, success rates, and possible complications were evaluated. Materials and Methods Fifty patients without PLSS (Control group) and 45 patients with PLSS (PLSS group) who were scheduled for total knee arthroplasty were studied prospectively. A CSEA was performed with patients in the left lateral position, and 10 mg of 0.5% isobaric tetracaine was injected through a 27 G spinal needle. An epidural catheter was then inserted for patient controlled analgesia. Successful spinal anesthesia was defined as adequate sensory block level more than T12. The number of skin punctures and the onset time were recorded, and maximal sensory block level (MSBL), time to 2-segment regression, success rate and complications were observed. Results The success rate of CSEA in Control group and PLSS group was 98.0%, and 93.3%, respectively. The median MSBL in PLSS group was higher than Control group [T4 (T2-L1) vs. T6 (T3-T12)] (p < 0.001). There was a significant difference in the number of patients who required ephedrine for the treatment of hypotension in PLSS group (p = 0.028). Conclusion The success rate of CSEA in patients with PLSS was 93.3%, and patients experienced no significant neurological complications. The MSBL can be higher in PLSS group than Control group.

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

    Background:Spinal anesthesia was considered as a reasonable anesthetic option in severe preeclampsia when cesarean delivery is indicated,and there is no indwelling epidural catheter or contraindication to spinal anesthesia.However,the ideal dose of intrathecal bupivacaine has not been quantified for cesarean delivery for severe preeclamptic patients.This study aimed to determine the ED50 and ED95 of intrathecal bupivacaine for severely preeclamptic patients undergoing elective cesarean delivery.Methods:Two hundred severely preeclamptic patients are undergoing elective cesarean delivery under combined spinal-epidural anesthesia enrolled in this randomized,double-blinded,dose-ranging study.Patients received 4 mg,6 mg,8 mg,or 10 mg intrathecal hyperbaric bupivacaine with 2.5 μg sufentanil.Successful spinal anesthesia was defined as a T6 sensory level achieved within 10 minutes after intrathecal drug administration and/or no epidural supplement was required during the cesarean section.The ED50 and ED95 were calculated with a logistic regression model.Results:ED50 and ED95 ofintrathecal bupivacaine for successful spinal anesthesia were 5.67 mg (95% confidence interval [CI]:5.20-6.10 mg) and 8.82 mg (95% CI:8.14-9.87 mg) respectively.The incidence of hypotension in Group 8 mg and Group 10 mg was higher than that in Group 4 mg and Group 6 mg (P < 0.05).The sensory block was significantly different among groups 10 minutes after intrathecal injection (P < 0.05).The use of lidocaine in Group 4 mg was higher than that in other groups (P < 0.05).The use of phenylephrine in Group 8 mg and Group 10 mg was higher than that in the other two groups (P < 0.05).The lowest systolic blood pressure before the infant delivery of Group 8 mg and Group 10 mg was lower than the other two groups (P < 0.05).The satisfaction of muscle relaxation in Group 4 mg was lower than other groups (P < 0.05).There was no significant difference in patients' satisfaction and the newborns

    Full Text Available Introduction: Major laparotomies generally herald high pain scores postoperatively and have high intraoperative hemodynamic shifts. Traditional analgesic regimens with intravenous opioids were supplanted with the superior epidural analgesia (EA in the mid-1980s. This was based on the perception that EA provided highly effective postoperative analgesia for patients undergoing major abdominal surgery. However, recent literature points to a high failure rate. We aimed to retrospectively audit our EA performance in terms of success and complications and take an in-depth look at factors associated with failure. Methods: We retrospectively reviewed charts and our EA forms over 6 months. Results: Our results show a low rate of mortality and neurological morbidity. However we have a high rate of failure of 37% as judged by high pain scores, use of adjuvant analgesics and also an unacceptably high rate of hypotension from epidural infusions, requiring fluid boluses, inotropes and Intensive Care Unit admission. Registrar level and senior insertion did not show any difference in failure rate. Conclusion: Level of training per se does not equate to experiential skip and prior level of experience with administration of this type of anesthesia. We can conclude that EA in our setting is safe but not effective and requires further and frequent scrutiny in terms of procedures, technical skill, education and perhaps looking at its cost-effectiveness and need for standardization.

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

    slower in the Sufentanil group as compared to the Propofol group during 100 minutes after beginning of surgery. Time for extubation and referral to post-anesthetic recovery unit (PACU was significantly shorter for the Propofol group, however sedation intensity and duration were longer in this group as compared to Sufentanil group. Recovery scores were similar for both groups. Three hours after PACU admission all patients were meeting criteria to be transferred to the ward. Transient arterial hypotension was observed in 2 Sufentanil group patients. CONCLUSIONS: Continuous thoracic epidural anesthesia with 0.2% ropivacaine (1.5 mg.kg-1 associated to propofol infusion provides effective and safe anesthesia for upper pediatric abdominal surgeries. Propofol infusion rate and sedation duration were decreased with the association of sufentanil.

    Dwarfism is characterized by short stature. Pregnancy in women with dwarfism is uncommon and cesarean section is generally indicated for delivery. Patients with dwarfism are high-risk population for both general and regional anesthesia, let alone in an emergency surgery. In this case report we present a 27-year-old Chinese puerpera with dwarfism who underwent emergency cesarean section under combined spinal and epidural anesthesia. It is an original case report, which provides instructive significance for anesthesia management especially combined spinal and epidural anesthesia in this rare condition. There was only one former article that reported a puerpera who underwent combined spinal and epidural anesthesia for a selective cesarean section.

    We recognized that the complexity and surgical nature of many interventional radiology procedures dictate essential radiologic involvement into traditional anesthesiologic areas. They reviewed our experience with a variety of interventional procedures to document complications and problems related to anesthetic use (or misuse) and compile recommendations for rational monitoring and control for these procedures. In particular, the authors have studied complications of drug therapies and the treatment of these complications; use of complex anesthesia procedures (e.g., epidural anesthesia, succinylcholine blockage); reasons for choice of drugs (e.g., fentanyl vs meperidine vs morphine); and medico-legal aspects of radiologist performing traditional anesthesiology-type procedures

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

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

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

  8. Inadvertent injection of succinylcholine as an epidural test dose

    Chryssa Pourzitaki

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

  9. Total spinal anesthesia in an achondroplasic patient: case report

    Amiri H R

    2008-06-01

    Full Text Available Background: Total spinal anesthesia is a complication of lumbar epidural anesthesia following undiagnosed subarachnoid or subdural injection of local anesthetic. Although many achondroplastic dwarfs have a normal spine, catheter insertion may be more problematic with a narrow epidural space making a subarachnoid tap more probable.  Other malformations associated with achondroplasia, such as prolapsed intervertebral discs, reduced interpedicular distance, shortened pedicles, and osteophyte formation, combined with a narrow epidural space may make identification of the space difficult and increases the risk of dural puncture. Furthermore, subarachnoid tap or dural puncture may be hard to recognize if a free flow of CSF is difficult to achieve due spinal stenosis. Yet, for those who meet the criteria, epidural regional anesthesia is frequently preferred over other forms, which often have more or more dangerous side effects in this type of patient.Case report: A 22-year-old achondroplastic male dwarf patient was scheduled for pelvic mass resection and was considered a candidate for continuous epidural anesthesia. The anesthesia became complicated by total spinal anesthesia, which was reversed following supportive management for about two hours.Conclusion: There is significant debate over the composition and volume of the test dose, especially for patients with achondroplasia. We nevertheless recommend repeated test-doses during the accomplishment of epidural anesthesia to exclude unintended intravascular, intrathecal or subdural injection, keeping in mind that a test dose of local anesthetic does not completely prevent complications.

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

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

    Rib fractures are common in trauma admissions and are associated with an increased risk of pulmonary complications, intensive care unit admissions, and mortality. Providing adequate pain control in patients with multiple rib fractures decreases the risk of adverse events. Thoracic epidural analgesia is currently the preferred method for pain control. This study compared outcomes in patients with multiple acute rib fractures treated with posterior paramedian subrhomboidal (PoPS) analgesia versus thoracic epidural analgesia (TEA). This prospective study included 30 patients with three or more acute rib fractures admitted to a Level I trauma center. Thoracic epidural analgesia or PoPS catheters were placed, and local anesthesia was infused. Data were collected including patients' pain level, adjunct morphine equivalent use, adverse events, length of stay, lung volumes, and discharge disposition. Nonparametric tests were used and two-sided p Pain rating was lower in the PoPS group (2.5 vs. 5; p = 0.03) after initial placement. Overall, there was no other statistically significant difference in pain control or use of oral morphine adjuncts between the groups. Hypotension occurred in eight patients, 75% with TEA and only 25% with PoPS. No difference was found in adverse events, length of stay, lung volumes, or discharge disposition. In patients with rib fractures, PoPS analgesia may provide pain control equivalent to TEA while being less invasive and more readily placed by a variety of hospital staff. This pilot study is limited by its small sample size, and therefore additional studies are needed to prove equivalence of PoPS compared to TEA. Therapeutic study, level IV.

    Spinal hematomas are a rare but serious complication of spinal epidural anesthesia and are typically seen in the epidural space; however, they have been documented in the subdural space. Spinal subdural hematomas likely exist within a traumatically induced space within the dural border cell layer, rather than an anatomical subdural space. Spinal subdural hematomas present a dangerous clinical situation as they have the potential to cause significant compression of neural elements and can be easily mistaken for spinal epidural hematomas. Ultrasound can be an effective modality to diagnose subdural hematoma when no epidural blood is visualized. We have reviewed the literature and present a full literature review and a case presentation of an 82-year-old male who developed a thoracolumbar spinal subdural hematoma after spinal epidural anesthesia. Anticoagulant therapy is an important predisposing risk factor for spinal epidural hematomas and likely also predispose to spinal subdural hematomas. It is important to consider spinal subdural hematomas in addition to spinal epidural hematomas in patients who develop weakness after spinal epidural anesthesia, especially in patients who have received anticoagulation.

    Bupivacaine is a long-acting local anesthetic (LA) used for cutaneous infiltration, peripheral nerve blocks, epidural and spinal anesthesia. However, its application may result in cardiovascular complications such as: hypotension, bradycardia, cardiac arrest and toxic myocardial injury. The authors describe a 53-year-old male with a history of cigarette smoking, admitted for an elective inguinal hernia surgery. Before surgery, the patient received subarachnoid injection of bupivacaine (20 mg). After the operation, he developed transient hypotension. Blood pressure returned to normal after gelofusine infusion; no sympathomimetics were administered. The male denied chest pain; however, ECG showed ST segment elevation coexisting with left ventricular anterolateral hypokinesia and decreased longitudinal strain in echocardiography. A significant increase in troponin I level was suggestive rather of myocardial infarction than of takotsubo cardiomyopathy. Urgent coronary angiography revealed left anterior descending artery spasm, which remitted after intracoronary nitroglycerin injection. Normalization of ECG and echocardiography was observed within a few days. The authors indicate that the presented atypical adverse effect of bupivacaine manifested itself with delay and that coronary spasm proceeded without angina. A close observation of the patient after anesthetic procedure with LA should be extended over the postoperative period.

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

Differences in postoperative pain, incidence of patient-controlled analgesia (PCA-related adverse effects, and risk factors for the need for rescue analgesics for 48 hours postsurgery in young (age 20–39 years and elderly (age ≥70 years patients were evaluated. Although there were no significant differences in postoperative pain intensity between the two groups until 6 hours postsurgery, younger patients experienced greater postoperative pain intensity compared with older patients 6–48 hours postsurgery. While younger patients exhibited greater incidence of numbness, motor weakness, and discontinuation of PCA postsurgery, elderly patients exhibited greater incidence of hypotension, nausea/vomiting, rescue analgesia, and antiemetic administration. Upon multivariate analysis, low fentanyl dosage and history of smoking were found to be associated with an increased need for rescue analgesia among younger patients, while physical status classification III/IV and thoracic surgery were associated with a decreased need for rescue analgesia among the elderly. Discontinuation of PCA was more frequent among younger patients than the elderly (18.5% vs 13.5%, P=0.001. Reasons for discontinuation of PCA among young and elderly patients, respectively, were nausea and vomiting (6.8% vs 26.6%, numbness or motor weakness (67.8% vs 11.5%, urinary retention (7.4% vs 8.7%, dizziness (2.2% vs 5.2%, and hypotension (3.1% vs 20.3%. In conclusion, PCEA was more frequently associated with numbness, motor

    Transumbilical Laparo-Endoscopic Single Site (LESS) surgery promises improved cosmesis, quick recovery, reduced postoperative pain and shorter length of hospital stay. Since only a simple umbilical incision is used, LESS surgery can be completed with segmental epidural anesthesia. This study describes the evolution of our technique of LESS cholecystectomy from a combination of spinal and epidural anesthesia to thoracic epidural alone and presents our experience with its safety, the observed morbidity, and the reported patient satisfaction. In August 2009, a prospective evaluation of LESS cholecystectomy with regional anesthesia was undertaken. We recruited patients with chronic cholecystitis or symptomatic cholelithasis. Blood loss, operative time, complications, and length of hospital stay were measured. Preoperatively and 14 days postoperatively, outcome and symptom resolution were scored. Fifteen consecutive patients underwent LESS cholecystectomy; first with combined spinal-epidural (CSE), and then with thoracic epidural anesthesia alone. Immediate postoperative pain and discomfort were well tolerated. VAS scores upon admission to PACU were 0.4 (1.7±2.2). At postoperative day 14, the patients scored high values for "Satisfaction", 10 (10±1.0) and "Cosmesis", 10 (9.3±1.5). LESS cholecystectomy with epidural anesthesia can be undertaken safely. Patient satisfaction and cosmesis are particularly prominent amongst our patients. Our experience supports further utilization of epidural anesthesia for selected patients undergoing LESS cholecystectomy.

    To assess the diagnostic accuracy of heavily T2-weighted magnetic resonance myelography (MRM) in patients with spontaneous intracranial hypotension (SIH). Patients with SIH were recruited prospectively, and first underwent MRM and then computed tomographic myelography (CTM). The results of MRM were validated with the gold standard, CTM, focusing on 1) CSF leaks along the nerve roots, 2) epidural CSF collections, and 3) high-cervical (C1-3) retrospinal CSF collections. Comparisons of these 3 findings between the 2 studies were made by kappa statistics and agreement rates. Targeted epidural blood patches (EBPs) were placed at the levels of CSF leaks if supportive treatment failed. Nineteen patients (6 men and 13 women, mean age 37.9 +/- 8.6 years) with SIH completed the study. MRM did not differ from CTM in the detection rates of CSF leaks along the nerve roots (84% vs 74%, p = 0.23), high-cervical retrospinal CSF collections (32% vs 16%, p = 0.13), and epidural CSF collections (89% vs 79%, p = 0.20). MRM demonstrated more spinal levels of CSF leaks (2.2 +/- 1.7 vs 1.5 +/- 1.5, p = 0.011) and epidural collections (12.2 +/- 5.9 vs 7.1 +/- 5.8, p localizing CSF leaks for patients with spontaneous intracranial hypotension. This noninvasive technique may be an alternative to computed tomographic myelography before targeted epidural blood patches.

    Objective To investigate and compare the efficacy of ropivacaine and bupivacaine on basic signs of patients during cesarean section under combined spinal-epidural anesthesia. Methods 148 women who underwent cesarean section in the Department of Gynae-cology and Obstetrics in the hospital from October 2015 to May 2016 were selected and randomly divided into the ropivacaine group and the bupivacaine group according to the narcotic drugs used. The ropivacaine group was given ropivacaine anesthesia and the bupiva-caine group was given bupivacaine anesthesia. The changes of hemodynamics in the two groups during drug administration and operation were monitored. The status of sensory and motor block was observed, and the anesthetic effect was evaluated. The incidence of adverse reactions and neonatal status were recorded. Results During anesthesia, HR and MAP showed a significant decreasing trend( P 0. 05 ); the block beginning time and the longest block time in ropivacaine group were significantly longer than those in bupivacaine group ( P 0. 05 ) but the difference in total incidence of adverse reactions was significant ( P 0. 05 ) . Conclusion The anesthetic efficacy of both ropivacaine and bupivacaine are good. However, ropivacaine is more suitable for cesarean section under combined spinal-epidural anesthesia since it has little effect on heart rate and blood pressure of pregnant women, and its sensory and motor block time is longer with few adverse reactions.%目的:探讨并比较罗哌卡因与布比卡因对腰-硬联合麻醉剖宫产手术中患者基本体征指标的影响。方法选取2015年10月至2016年5月妇产科接受剖宫产手术的患者148例,根据接受麻醉药物的不同,随机均分为罗哌卡因组(A组)和布比卡因组(B组),监测两组孕妇的给药及手术过程的血流动力学变化,观察两组孕妇的感觉、运动阻滞情况,评估麻醉效果,记录术后不良反应及新生儿情况。结果

    Neuraxial anesthesia has been widely used in China. Recently, Chinese anesthesiologists have applied nerve stimulator and ultrasound guidance for peripheral nerve blocks. Nationwide surveys about regional anesthesia practices in China are lacking. We surveyed Chinese anesthesiologists about regional anesthesia techniques, preference, drug selections, complications, and treatments. A survey was sent to all anesthesiologist members by WeChat. The respondents can choose mobile device or desktop to complete the survey. Each IP address is allowed to complete the survey once. A total of 6589 members read invitations. A total of 2654 responses were received with fully completed questionnaires, which represented an overall response rate of 40%. Forty-one percent of the respondents reported that more than 50% of surgeries in their hospitals were done under regional anesthesia. Most of the participants used test dose after epidural catheter insertion. The most common drug for test dose was 3-mL 1.5% lidocaine; 2.6% of the participants reported that they had treated a patient with epidural hematoma after neuraxial anesthesia. Most anesthesiologists (68.2%) performed peripheral nerve blocks as blind procedures based on the knowledge of anatomical landmarks. A majority of hospitals (80%) did not stock Intralipid; 61% of the respondents did not receive peripheral nerve block training. The current survey can serve as a benchmark for future comparisons and evaluation of regional anesthesia practices in China. This survey revealed potential regional anesthesia safety issues in China.

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

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

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

    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.

    Radionuclide cisternography may be helpful in understanding pathophysiology of postural headache and low CSF pressure in patients with spontaneous intracranial hypotension. The purpose of this study was to characterize radionuclide cisternogrpahic findings of spontaneous intracranial hypotension. The study population consists of 15 patients with spontaneous intracranial hypotension. Diagnosis was based on their clinical symptoms and results of lumbar puncture. All patients underwent radionuclide cisternography following injection of 111 to 222 MBq of Tc-99m DTPA into the lumbar subarachnoid space. Sequential images were obtained between 1/2 hour and 24 hour after the injection of Tc-99m DTPA. Radioactivity of the bladder, soft tissue uptake, migration of radionuclide in the subarachnoid space, and extradural leakage of radionuclide were evaluated according to the scan time. Radionuclide cisternogram showed delayed migration of radionuclide into the cerebral convexity (14/15), increased soft tissue uptake (11/15), and early visualization of bladder activity at 30 min (6/10) and 2 hr (13/13). Cisternography also demonstrated leakage site of CSF in 4 cases and 2 of these were depicted at 30min. Epidural blood patch was done in 11 patients and headache was improved in all cases. The characteristics findings of spontaneous intracranial hypotension were delayed migration of radionuclide and early visualization of the soft tissue and bladder activity. These scintigraphic findings suggest that CSF leakage rather than increased CSF absorption or decreased production may be the main pathophysiology of spontaneous intracranial hypotension. Early and multiple imaging including the bladder and soft tissue is required to observe the entire dynamics of radionuclide migration

    Clinical picture of development of segmental blocking after subarachnoidal injection of hyperbaric solutions of 0.75% bupivacaine, 5% ultracaine, and isobaric 0.5% bupivacaine is studied. A total of 152 patients operated on the lower part of the body and the lower limbs were examined under conditions of single, prolonged subarachnoidal, and combined spinal epidural anesthesia. Ultracaine and bupivacaine in different concentrations with different barism provided anesthesia equivalent by the efficacy, depth, and dissemination of sensory block. Segmental blocking with 5% ultracaine was characterized by the shortest latent period (3.14 +/- 0.16 min, p anesthesia in comparison with a single injection, and combined spinal epidural anesthesia shortened the latent period of segmental blocking and ensured intraoperative anesthesia and postoperative analgesia at the expense of the epidural component.

    Epidural anesthesia is a common technique for perioperative analgesia and chronic pain treatment. Since ultrasonography is insufficient for depicting the human vertebral surface, most examiners apply epidural puncture by body surface landmarks on the back such as the spinous process and scapulae without any imaging, including ultrasonography. The puncture route to the epidural space at thoracic vertebrae is much narrower than that at lumber vertebrae, and therefore, epidural anesthesia at thoracic vertebrae is difficult, especially for a beginner. Herein, a novel imaging method is proposed based on a bi-static imaging technique by making use of the transmit beam width and direction. In an in vivo experimental study on human thoracic vertebrae, the proposed method succeeded in depicting the vertebral surface clearly as compared with conventional B-mode imaging and the conventional envelope method. This indicates the potential of the proposed method in visualizing the vertebral surface for the proper and safe execution of epidural anesthesia.

    Hypotension is commonly encountered in association with anaesthesia and surgery. Uncorrected and sustained it puts the brain, heart, kidneys, and the fetus in pregnancy at risk of permanent or even fatal damage. Its recognition and correction is time critical, especially in patients with pre-existing disease that compromises organ perfusion. To examine the role of a previously described core algorithm "COVER ABCD-A SWIFT CHECK", supplemented by a specific sub-algorithm for hypotension, in the management of hypotension when it occurs in association with anaesthesia. Reports of hypotension during anaesthesia were extracted and studied from the first 4000 incidents reported to the Australian Incident Monitoring Study (AIMS). The potential performance of the COVER ABCD algorithm and the sub-algorithm for hypotension was compared with the actual management as reported by the anaesthetist involved. There were 438 reports that mentioned hypotension, cardiovascular collapse, or cardiac arrest. In 17% of reports more than one cause was attributed and 550 causative events were identified overall. The most common causes identified were drugs (26%), regional anaesthesia (14%), and hypovolaemia (9%). Concomitant changes were reported in heart rate or rhythm in 39% and oxygen saturation or ventilation in 21% of reports. Cardiac arrest was documented in 25% of reports. As hypotension was frequently associated with abnormalities of other vital signs, it could not always be adequately addressed by a single algorithm. The sub-algorithm for hypotension is adequate when hypotension occurs in association with sinus tachycardia. However, when it occurs in association with bradycardia, non-sinus tachycardia, desaturation or signs of anaphylaxis or other problems, the sub-algorithm for hypotension recommends cross referencing to other relevant sub-algorithms. It was considered that, correctly applied, the core algorithm COVER ABCD would have diagnosed 18% of cases and led to resolution in

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

    To assess the usefulness of imaging modalities in the detection of spinal CSF leakage in spontaneous intracranial hypotension. Fifteen patients who complained of postural headache without any preceding cause showed typical brain MR findings of intracranial hypotension, including radiologically confirmed CSF leakage. All fifteen underwent brain MRI and radionuclide cisternography. CT myelography was performed in eight patients and spinal MRI in six. Medical records, imaging findings and the incidence of spinal CSF leakage during each modality were retrospectively reviewed. CSF leakage was most common at the cervicothoracic junction, where in seven of 15 cases it was seen on radionuclide cisternography as increased focal paraspinal activity. Leakage was noted at the mid-tho-racic level in three patients, at the upper thoracic level in two, and at the cervical and lumbar levels in the remaining two. In two patients multiple CSF leaks were noted, and in all, early radioactive accumulation in the bladder was visualized. CT myelography revealed extrathecal and paraspinal contrast leakage in three of eight patients, and among those who underwent spinal MRI, dural enhancement was observed at the site of CSF leakage in all six, abnormal CSF signal in the neural foramen in one, and epidural CSF collection in one. Radionuclide cisternography is a useful method for the detection of CSF leakage in spontaneous intracranial hypotension. CT myelography and spinal MRI help determine the precise location of leakage

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

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

    Cranial magnetic resonance imaging (MRI) findings in spontaneous intracranial hypotension (SIH) are well known, while spinal studies have received less attention. Radiological spinal findings in nine patients with SIH are presented, looking for possible characteristic features. Five of the nine patients had histories of previous minor trauma, one of previous surgery; in three patients possible relevant preceding events were completely absent. All nine patients had cervical, seven thoracic, and four lumbar spine MRI studies; post-contrast studies were obtained in seven cases, MRI myelograms in five. Radioisotope myelocisternography was performed in four patients and myelo-CT in four. Epidural fluid collections were found in seven patients. In six cases the dural sac had collapsed, with a festooned appearance; intense epidural enhancement on post-contrast studies demonstrated marked dilatation of the epidural venous plexus. In three cases an irregular root sleeve suggested a possible point of cerebrospinal fluid (CSF) leakage. Myelo-CT demonstrated the CSF fistula in two cases, radioisotope myelocisternography in three. The pattern of spinal abnormalities is different from that seen in cranial MRI for anatomical reasons: in the spinal canal the dura is not adherent to the bone; therefore, collapse of the dural sac and dilatation of epidural venous plexus occur, rather than subdural hematomas. In most cases the search for the dural tear is difficult. Radioisotope cisternography is probably the most sensitive examination for documenting the leakage of CSF out of the subarachnoid space; myelo-CT may precisely demonstrate the point of the CSF fistula, whereas MRI may only suggest it.

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

Los síntomas se mantuvieron a pesar del tratamiento médico, por lo que se realizó una tomografía axial simple de cráneo que mostró la presencia de un hematoma epidural subagudo temporoparietal derecho, con desplazamiento de estructuras de la línea media. Se realizó una craneotomía temporoparietal derecha para la evacuación del hematoma posterior. El paciente evolucionó satisfactoriamente y se recuperó por completo, tanto clínica como imaginológicamente.This is the case of a patient presenting with right temporoparietal subacute hematoma secondary to a physical act of aggression. In clinical picture at 24 hours there was predominance of headache of moderate intensity with drowsiness and slight psychomotor restlessness. The skull single radiographies didn't show alterations. Symptoms remained despite the medical treatment, thus a single skull axial tomography was carried out showing the presence of a right temporoparietal subacute epidural hematoma with displacement from the middle line structures. A right temporoparietal craniotomy was carried out to evacuation of the posterior hematoma. Patient evolved satisfactorily with a total recovery as much clinical as imaging.

    Spontaneous intracranial hypotension (SIH) is an uncommon but increasingly recognized syndrome. Orthostatic headache with typical findings on magnetic resonance imaging (MRI) are the key to diagnosis. Delayed diagnosis of this condition may subject patients to unnecessary procedures and prolong morbidity. We describe six patients with SIH and outline the important clinical and neuroimaging findings. They were all relatively young, 20-54 years old, with clearly orthostatic headache, minimal neurological signs (only abducent nerve paresis in two) and diffuse pachymeningeal gadolinium enhancement on brain MRI, while two of them presented subdural hygromas. Spinal MRI was helpful in detecting a cervical cerebrospinal fluid leak in three patients and dilatation of the vertebral venous plexus with extradural fluid collection in another. Conservative management resulted in rapid resolution of symptoms in five patients (10 days-3 weeks) and in one who developed cerebral venous sinus thrombosis, the condition resolved in 2 months. However, this rapid clinical improvement was not accompanied by an analogous regression of the brain MR findings that persisted on a longer follow-up. Along with recent literature data, our patients further point out that SIH, to be correctly diagnosed, necessitates increased alertness by the attending physician, in the evaluation of headaches

    Neuraxial anesthesia combined with general anesthesia has become a widely accepted method of providing effective postoperative analgesia and decreasing intraoperative anesthetic needs in the pediatric population. In clinical practice, there still appears to be hesitancy for the use of a neuraxial technique (spinal or epidural) in patients at risk for bacteremia or with an on-going systemic infection. However, evidence-based medicine lacks any data to support an increase in the risk of infecti...

    Emergency anesthesia in elderly patients aged 65 years and older is complex. The occurrence of intraoperative incidents and arterial hypotension is conditioned by patients' initial health status and by the quality of intraoperative management. This study aimed to determine the incidence of intra-anesthetic arterial hypotension in elderly patients during emergency surgery and to assess the involvement of certain factors in its occurrence: age, sex, patient's history, ASA class, anesthetic technique. We conducted a retrospective descriptive and analytical study in the Emergency Surgery Department at the Aristide Le Dantec University Hospital from 1 March 2014 to 28 February 2015. We collected data from 210 patients out of 224 elderly patients aged 65 years and older undergoing emergency anesthesias (10.93%). Data of 101 men and 109 women were included in the analysis, of whom 64.3% had at least one defect. Patients' preoperative status was assessed using American Society of Anesthesiology (ASA) classification: 71% of patients were ASA class 1 and 2 and 29% were ASA class 3 and 4. Locoregional anesthesia was the most practiced anesthetic technique (56.7%). 28 patients (13.33%) had intra-anesthetic arterial hypotension, of whom 16 under general anesthesia and 12 under locoregional anesthesia. It was more frequent in patients with high ASA class and a little less frequent in patients with PAH and underlying heart disease. Arterial hypotension in elderly patients during emergency surgery exposes the subject to the risk of not negligible intraoperative hypotension, especially in patients with high ASA class. Prevention is based on adequate preoperative assessment and anesthetic management.

    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 Objective: To study the influence of general anesthesia, epidural anesthesia and combined spinal and epidural anesthesia method on stress reaction and hemodynamics for elderly orthopedics patients during operations. Methods: A total of 90 cases of elder patients who received orthopedic operations were randomly divided to group A, B and C, with 30 cases per group. Three groups of patients were separately given by general anesthesia, epidural anesthesia and combined spinal and epidural anesthesia for operations; The variations of adrenocorticotrophic hormone (ACTH, Cortisol (Cor, β-endorphin (β-EP, Angiotensin- Ⅱ(Ang-Ⅱ, heart rate (HR and blood pressure (SBP, DBP on patients in three groups before anesthesia (T0, during skin incision (T1, after skin incision (T2 and extubation after operation (T3 were compared and analyzed. Results: During T1, T2, ACTH, Cor, β-EP and Ang-Ⅱlevels in 3 groups of patients were significantly higher than those during T0; SBP and DBP were significantly lower than that during T0; HR during T2 was significantly lower than that during T0; During T3, every index in 3 groups were recovered to levels close to that during T0; During T1, T2, ACTH, Cor, β-EP, Ang-Ⅱ levels in group B and C were significantly lower than that in group A. And levels in C was lower than that in B; SBP and DBP in group B and C were significantly higher than A. No HR statistical significance appeared between each group. Conclusions: During clinical anesthesia, we should choose suitable anesthesia method combined with actual situations of patients. Combined spinal and epidural anesthesia had a slight influence on hemodynamics of elder orthopedics patients during operation, and it could effectively alleviate stress reaction during operation.

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

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

    A computerised record was used to collect data following an anesthesiological check-up of pregnant women at approximately 30 weeks of pregnancy. The record was input onto a portable PC in the anesthesia outpatient clinic, memorized on disk (3.5") and then transferred onto a PC network (one PC for each operating theatre) for "real time" consultation of each patient's data. All pregnant women attending the antenatal clinico were also given a folder illustrating epidural anesthetic techniques. Seven hundred and nine outpatient visits have been performed over the past two years with a 62% utilisation ratio. The collection of data using a computerised system allows a rapid and efficacious system of communication to be set up among the membranes of the anesthesiological team, thus encouraging the use of epidural techniques during labour. The distribution of the folder also facilitated the task of the anesthetist who found that pregnant women visiting the anesthesia clinic were already familiar with the epidural technique.

    Viewed from a cultural-ethical perspective, anesthesiology can be understood as a comprehensive concept of medicine in general. As such it contains two dilemmas: very often pain must be inflicted in order to alleviate pain and this can only be done by somebody who is himself relatively free of pain. The necessary apathy or anesthesia of the anesthetist is correlated with a general twentieth century-type of perception: the cool observer. Nevertheless, it is also a modern variation of the original religious constellation of the priest in relationship to the sick person. Curing occurs by representation. The weak self of the sick person is able to take over the strong self, represented by the therapist. In twentieth century art and literature this process of self-therapy by representation was often illustrated. On the background of a phenomenological philosophy that process can be understood as the regaining of a balance between body and soul. In the psalms of the biblical Book of Job there a variety of fundamental forms of pain which may be helpful even in this secular age.

    The specific aim of this review is to report the features of intracranial pressure changes [spontaneous intracranial hypotension (SIH) and idiopathic intracranial hypertension (IIH)] in children and adolescents, with emphasis on the presentation, diagnosis, and treatment modalities. Headache associated with intracranial pressure changes are relatively rare and less known in children and adolescents. SIH is a specific syndrome involving reduced intracranial pressure with orthostatic headache, frequently encountered connective tissue disorders, and a good prognosis with medical management, initial epidural blood patching, and sometimes further interventions may be required. IIH is an uncommon condition in children and different from the disease in adults, not only with respect to clinical features (likely to present with strabismus and stiff neck rather than headache or pulsatile tinnitus) but also different in outcome. Consequently, specific ICP changes of pediatric ages required specific attention both of exact diagnosis and entire management.

    Patients who complain headache, neck pain, dizziness or vertigo, tinnitus, blurred vision, loss of concentration, memory disturbance and fatigue for over one year after mild head injury and whiplash injury are diagnosed as post-traumatic syndrome. Mechanism and treatment of post-traumatic syndrome are not well established. We studied radioisotope (RI) cisternography and enhanced brain magnetic resonance imaging (MRI) for the patient of post-traumatic syndrome. Of 175 cases in post-traumatic syndrome 141 cases (120 cases of motor vehicle accident, 21 cases of sports injury) were diagnosed, as intracranial hypotension (cerebrospinal fluid hypovolemia). RI cisternography showed 86% positive findings (early accumulation of RI in bladder and leakage). Prominent findings in MRI were dilatation of subdural space and venous dilatation. In every case epidural blood patch was performed and symptoms were improved in almost 70% of patients. This study revealed cerebrospinal fluid hypovolemia might be one cause of post-traumatic syndrome. (author)

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

    The demand for peripheral nerve blocks and neuroaxial blocks from both patients and surgeons has increased over the last few years. This change in attitude towards regional anesthesia is prompted by the insight that adequate perioperative pain management leads to earlier ambulation, shorter hospital stay, reduced cost and increased patient satisfaction. To avoid serious complications of these techniques structured residency programs need to be available. Until 2004, the Residency Review Committee for Anesthesiology in the United States required a minimum of 50 epidurals, 40 spinals and 40 peripheral nerve blocks during residency. Similarly, the German Society for Anesthesia and Intensive Care required 100 neuroaxial blocks and 50 peripheral nerve blocks. In 2004 the American Society of Regional Anesthesia and Pain Medicine endorsed standardized guidelines for regional anesthesia fellowships which regulate the administrative, equipment and educational demands. This review introduces the reader to the different teaching methods available, including cadaver workshops, three-dimensional videoclips, video filming, ultrasound guidance and acoustic assist devices as well as demonstrating their advantages and disadvantages. Moreover, an overview is given of future residency training programs, which integrate administrative, material and educative demands as well as the teaching means into the daily clinical routine.

    Hypobaric spinal anesthesia was administered to 40 patients undergoing lower limb surgery. Twenty-nine of the patients were debilitated geriatric patients who presented with orthopedic emergencies, in most cases a fractured hip. Hypobaric spinal anesthesia was found to be a simple and safe procedure that provided adequate analgesia. Due to its inherent nature, hypobaric spinal anesthesia does not necessitate positioning of the patient on the injured, painful side (unlike hyperbaric spinal or epidural anesthesia) and, therefore, facilitates a smooth and painless transfer of the patient to the operating table. Complications encountered were similar to those following hyperbaric anesthesia.

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

    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.

    Full Text Available Neuraxial anesthesia combined with general anesthesia has become a widely accepted method of providing effective postoperative analgesia and decreasing intraoperative anesthetic needs in the pediatric population. In clinical practice, there still appears to be hesitancy for the use of a neuraxial technique (spinal or epidural in patients at risk for bacteremia or with an on-going systemic infection. However, evidence-based medicine lacks any data to support an increase in the risk of infectious complications following neuraxial anesthesia. We present two pediatric patients with intra-abdominal infectious processes who received caudal epidural blockade for postoperative operative analgesia. The use of neuraxial techniques in patients at risk for bacteremia is reviewed, evidence-based medicine regarding the risks of infection discussed, and the potential favorable effects of neuraxial blockade on the neurohumoral response to sepsis and the systemic inflammatory responses presented.

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

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

    Hypotension is common in patients undergoing surgery in the sitting position under general anesthesia, and the risk may be exacerbated by the use of antihypertensive drugs taken preoperatively. The purpose of this study was to compare hypotensive episodes in patients taking antihypertensive medications with normotensive patients during shoulder surgery in the beach chair position. Medical records of all patients undergoing shoulder arthroscopy during a 44-month period were reviewed retrospectively. The primary endpoint was the number of moderate hypotensive episodes (systolic blood pressure ≤ 85 mmHg) during the intraoperative period. Secondary endpoints included the frequency of vasopressor administration, total dose of vasopressors, and fluid administered. Values are expressed as mean (standard deviation). Of 384 patients who underwent shoulder surgery, 185 patients were taking no antihypertensive medication, and 199 were on at least one antihypertensive drug. The antihypertensive medication group had more intraoperative hypotensive episodes [1.7 (2.2) vs 1.2 (1.8); P = 0.01] and vasopressor administrations. Total dose of vasopressors and volume of fluids administered were similar between groups. The timing of the administration of angiotensin-converting enzyme inhibitors and of angiotensin receptor antagonists (≤ 10 hr vs > 10 hr before surgery) had no impact on intraoperative hypotension. Preoperative use of antihypertensive medication was associated with an increased incidence of intraoperative hypotension. Compared with normotensive patients, patients taking antihypertensive drugs preoperatively are expected to require vasopressors more often to maintain normal blood pressure.

    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.

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

    This is the case of a patient presenting with right temporoparietal subacute hematoma secondary to a physical act of aggression. In clinical picture at 24 hours there was predominance of headache of moderate intensity with drowsiness and slight psychomotor restlessness. The skull single radiographies didn't show alterations. Symptoms remained despite the medical treatment, thus a single skull axial tomography was carried out showing the presence of a right temporoparietal subacute epidural hematoma with displacement from the middle line structures. A right temporoparietal craniotomy was carried out to evacuation of the posterior hematoma. Patient evolved satisfactorily with a total recovery as much clinical as imaging. (author)

    Full Text Available Background: The benefit of prophylactic combination therapy using crystalloid and colloid preload with ephedrine has not been cleared to prevent maternal hypotension after spinal anesthesia at cesarean delivery. This study evaluated the efficacy of three combinational methods to prevent hypotension following spinal anesthesia. Materials and Methods: In this prospective double blind trial, 150 candidates of elective cesarean delivery under spinal anesthesia were randomly allocated to three treatment groups; 1---Ringer′s Lactate (RL solution (15 ml/kg plus Hemaxel (7 ml/kg preload, 2---RL solution (15 ml/kg preload plus ephedrine (15 mg, IV, bolus, 3---Hemaxel (7 ml/kg preload plus ephedrine (15 mg, IV, bolus. Maternal hemodynamic changes during 60 min after spinal injection, nausea/vomiting, and neonatal condition were compared among the groups. Results: The cumulative incidence of hypotension was 44%, 40%, and 46% in groups 1 to 3, respectively. There were not significant differences in supplementary ephedrine requirement among groups which received or among groups which did not receive prophylactic ephedrine. Groups were not different in the incidence of hypertension and nausea or vomiting. There were no significant differences among groups in Apgar scores at 1 or 5 min and umbilical artery PH. Conclusion: Combination of preventive methods decreased the occurrence of hypotension following spinal anesthesia to an acceptable level. Overall, the most effective method was a combination of crystalloid preload with ephedrine.

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

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

    Full Text Available The potential uses of dexmedetomidine (DEX, a highly selective α2 - adrenoceptor agonist are very diverse. DEX appears to mimic many of the actions of mythical ′ideal′ sedative/analgesic agent. Although not orally active, DEX shows good bioavailability when administered via various other routes like intranasal, buccal, IM than intra-venous. DEX has similar pharmacokinetics in all age groups. Its side effects are predictable and easily treatable, hence it has found place as a part of fast-tracking anesthesia regimens in children. DEX is the sedative of choice for peri-operative use in high risk patients, since it is cardioprotective, neuroprotective and renoprotective. Premedication with DEX obtunds the autonomic pressor responses due to laryngoscopy and endotracheal intubation when used as an adjuvant to general anesthesia. DEX in high doses offers another approach to managing morbidly obese patients and patients with a compromised airway; without causing any cardio-respiratory depression. It is near ideal hypotensive agent used for controlled hypotension. Its value as a primary sedative and analgesic is becoming more accepted and evident in critically ill patients; in adult and paediatric intensive care units. Besides use in locoregional anesthesia, it is also used as an opioid substitute, for treatment of substance withdrawal, as an anti-shivering agent, for treatment of delirium and as an end of life medication. Availability of an antidote (Atipamezole with similar elimination half life is taking the drug into new frontiers. However, use of DEX is contraindicated in patients with hepatic failure, hypovolemic shock, advanced heart block or ventricular dysfunction.

    Full Text Available Objective. To choose the optimum technique of general anesthesia in the surgical treatment of patients with postinfarct left ventricular aneurysms (PLVA.Materials and methods. Fifty-four patients operated on for PLVA were examined. They were divided into 4 groups according to the basic technique of general anesthesia: 1 intravenous anesthesia based on propofol and fentanyl; 2 inhalation sevoflurane anesthesia with fentanyl enhancement of the analgesic component; 3 inhalation isoflurane anesthesia with fentanyl enhancement of the analgesic component; 4 general anesthesia in combination with epidural blockade. Central hemodynamics was investigated by the thermodilution technique and the perioperative period was also studied.Results and discussion. None of the general anesthesia techniques affected the development of perioperative complications. However, with decreased myocardial reserves, high thoracic epidural anesthesia should be applied with caution as it causes a significant desympathization, which may lead to impairments of the autoregulatory mechanisms of coronary blood flow and aggravate existing contractile disorders. Intravenous and inhalation anesthesia techniques provide a fair hemodynamic stability at all stages of surgical treatment. Inhalation anesthesia has a number of advantages: less cost and the possibility of rapid activation of patients in the early postoperative period.

    Objective: To determine the incidence of intraoperative anesthesia-related complications of laparoscopic cholecystectomy. Results: One hundred patients with male to female ratio of 1:8.09 in the age range of 20-80 years (mean 39 years) underwent general anesthesia for laparoscopic cholecystectomy. The duration of operation in 94 laparoscopic cholecystectomy was from 20 to 80 minutes (mean 60.63 minutes). The incidence of intraoperative hypotension was 9%. Four percent of the patients developed arrhythmias. Increase in end-tidal-carbon dioxide (ETCO/sub 2/) was observed in 3% of cases. Conversion rate to open cholecystectomy was 6%. Damage to intraabdominal vessels with trocar insertion occurred in 1% of cases. Conclusion: Although laparoscopic cholecystectomy has major surgical and anesthetic advantages, there are anesthesia related complications requiring specific anesthetic interventions to improve patients outcome without compromising their safety.

    Post thoracotomy chronic pain is a severe problem that affects the majority of patients and decreases the quality of life. The purpose of this study is to evaluate the long-term effects of thoracal epidural levobupivacaine and intravenous dexketoprofen analgesia formed pre-emptively on the wound site pain after major thoracotomy operations. This randomised, prospective and double-blind study was performed with 60 patients undergoing thoracic surgery. Patients were divided into three groups; Control Group (Group C), Pre-emptive Epidural Group (Group PE) and Pre-emptive Dexketoprofen + Epidural Group (Group PED). Patients in the Group C did not receive epidural analgesics and i.v. dexketoprofen before and during the operation. 10-15 ml 0.125% levobupivacaine was given to cases in Group PE pre-emptively through epidural catheter before the anesthesia induction. The cases in Group PED were given 10-15 ml 0.125% epidural levobupivacaine and 50 mg dexketoprofen with i.v. infusion pre-emptively. The VAS score was found to be lower in Group PED during postoperative 24 and 48 hours and before the discharge (P0.05). A statistically significant decrease was determined in the VAS score in Group PED during the sixth month, compared to the other groups (Pdexketoprofen and thoracal epidural analgesia reduce the chronic post-thoracotomy pain.

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

    Intravenous droperidol has strong evidence for antiemetic efficacy in high risk patients for prevention of postoperative nausea and vomiting (PONV). However it is not clear whether continuous epidural administration of doroperidol prevent PONV. It has been reported that epidural adrenaline decreases PONV; therefore we prospectively compared the effectiveness of epidural droperidol and adrenaline for prophylaxis of PONV. Eighty-six patients were scheduled for abdominal gynecological surgery under general-epidural anesthesia in the study. Patients were randomly assigned to droperidol group or adrenaline group. We investigated the incidences of PONV, the frequency of using the antiemetics. There was no statistical difference between the groups. The incidences of PONV were 27.9% (doropeidol group) and 58.1% (adrenaline group), respectively (P = 0.0046). The frequency of the anti-emetics use were 18.6% and 41.9%, respectively (P = 0.0189). There was one patient who needed cancellation of continuous epidural administration for vomiting in adrenaline group, but no patient in doropeidol group. The results suggest that epidural droperidol effectively decreases PONV in high risk patients. However epidural adrenaline might be ineffective.

    Full Text Available SCN5A gene mutations can lead to ion channel defects which can cause cardiac conduction disturbances. In the presence of specific ECG characteristics, this mutation is called Brugada syndrome. Many drugs are associated with adverse events, making anesthesia in patients with SCN5A gene mutations or Brugada syndrome challenging. In this case report, we describe a pregnant patient with this mutation who received epidural analgesia using low dose ropivacaine and sufentanil during labour.

Methods: Ninety hypertensive patients undergoing upper abdominal operations were randomly allocated to equal divided epidural anesthesia, general anesthesia and combined Groups. Plasma neuropeptide Y(NPY) concentrations were measured before anesthesia, at 15 min after anesthesia, 20 min after operation and 10 min after completion of the operation. Results: BP, HR and NPY were significantly changed in both E group and G group after anesthesia and operation (compared vs before anesthesia, p<0.01). BP, HR and NPY were significantly changed in C group after operation compared with those in both E and G group (p<0.05) . Conclusion: The combined anesthesia method is effective in inhibits the stress response during upper abdominal operation in the hypertensive patients

    Full Text Available Background and objectives Provision of standard childbirth facilities has been considered as an important healthcare issue for a long time. The physical and psychological states of mothers are important factors determining the fate of delivery. Therefore, several programs have been established to decrease the mother-child mortality rates and the complications of delivery. One of the most common approaches for controlling the pain of delivery is application of local anesthesia such as epidural, spinal, or a combination of these methods. It has been shown that complications of epidural anesthesia are less than other methods of local anesthesia employed for the painless delivery. In this study, a comparison is made between two groups of 80 neonates delivered by either NVD or EU.Methods A form was designed for collection of data including Apgar score at first minute, need for CPR, NICU admission, FHR variability, breast feeding time, duration of hospital stay, and neonatal reflexes. The data were analyzed by chi-square and fisher tests using SPSS software.Results There was no significant difference between the neonates born by EA or NVD at the 95% confidence level.Conclusion Based on these findings it could be concluded that epidural anesthesia for delivery does not lead to neonatal complications more than that of NVD without pain control. Therefore, this method could be recommended to mothers, who choose elective cesarean section to avoid the pain of childbirth.Keywords: Heart Rate, Fetal ; Cardiopulmonary Resuscitation ; Intensive care, Neonatal; Anesthesia, Epidural

    The objective of this study is to describe the anatomic and imaging features of CSF venous fistulas, which are a recently reported cause of spontaneous intracranial hypotension (SIH). We retrospectively reviewed the records of patients with SIH caused by CSF venous fistulas who received treatment at our institution. The anatomic details of each fistula were recorded. Attenuation of the veins involved by the fistula was compared with that of adjacent control veins on CT myelography (CTM). Visibility of the CSF venous fistula on CTM and a modified conventional myelography technique we refer to as dynamic myelography was also compared. Twenty-two cases of CSF venous fistula were identified. The fistulas were located between T4 and L1. Ninety percent occurred without a concurrent epidural CSF leak. In most cases (82%), the CSF venous fistula originated from a nerve root sleeve diverticulum. On CTM, the abnormal veins associated with the CSF venous fistula were seen in a paravertebral location in 45% of cases, centrally within the epidural venous plexus in 32%, and lateral to the spine in 23%. Differences in attenuation between the fistula veins and the control veins was highly statistically significant (p CSF venous fistulas are an important cause of SIH that can be detected on both CTM and dynamic myelograph y and may occur without an epidural CSF leak. Familiarity with the imaging characteristics of these lesions is critical to providing appropriate treatment to patients with SIH.

    Full Text Available Background:Spinal anesthesia for cesarean section is associated with a high incidence of hypotension. The synergism between intrathecal opioids and local anesthetics may make it possible to achieve reliable spinal anesthesia with minimal hypotension using a minidose of local anesthetic. Methods: Forty-four preeclamptic parturients undergoing cesarean section were randomized in two groups of 22 patients. Group A received a spinal anesthetic of bupivacaine 6 mg plus fentanyl 20 µg , and group B received 12 mg bupivacaine. Hypotension was defined as a 30% decrease in systolic and diastolic pressure from baseline. Hypotension was treated with intravenous ephedrine boluses 2.5-5 mg up to maximum 50 mg. Results: All patients had satisfactory anesthesia. Five of 22 patients in group A required ephedrine, a single dose of 5 mg. Seventeen of 22 patients in group B required vasopressor support of blood pressure.The lowest recorded systolic,diastolic and mean blood pressures as fractions of the baseline pressures were 71.2%, 64.5% and 70.3% versus 59.9%, 53.5% and 60.2% respectively for group A versus group B. Conclusion: A “minidose” of 6 mg bupivacaine in combination with 20 µg fentanyl may provide satisfactory spinal anesthesia for cesarean section in the preeclamptic patient. The minidose combination caused dramatically less hypotension than 12 mg bupivacaine and nearly eliminated the need for vasopressor support of blood pressure.

    2004-01-01

    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.

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

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

    Obesity is associated with serious morbidity during pregnancy, and obese women also are at a high risk of developing complications during labor, leading to an increased risk for instrumental and Cesarean deliveries. The engagement of the obstetrical anesthetist in the management of this group of high-risk patients should be performed antenatally so that an appropriate management strategy can be planned in advance to prevent an adverse outcome. Good communication between all care providers is essential. The obese patient in labor should be encouraged to have a functioning epidural catheter placed early in labor. Apart from providing analgesia and alleviating physiological derangements during labor, the presence of a functioning epidural catheter can also be used to induce anesthesia quickly in the event of an emergency cesarean section, thus avoiding a general anesthesia, which has exceedingly high risks in the obese parturient. Successful management of the obese patient necessitates a comprehensive strategy that encompasses a multidisciplinary and holistic approach from all care-providers.

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

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

    Hypotension subsequent to spinal anesthesia occurs in a significant number of parturients undergoing lower segment caesarian section. Currently available methods to predict the incidence of hypotension, its severity and the outcome are sub-optimal. Many workers have used basal heart rate as one of the predictors. But using this method it is not possible to objectively analyze and predict the extent and severity of hypotension. We used an equipment measuring the level of sympatho-vagal balance, ANSiscope™, which derives these values from computed value of RR interval variability. We made a single measure of the value which was blinded to the patient and the anesthesiologist. We studied one hundred eight patients who underwent lower segment caesarian section under spinal anesthesia and found the variability of preoperative ANSindex (% activity displayed by the equipment) from 9 to 65 %. Higher ANSindex value was significantly associated with post spinal hypotension (p 0.017). A value of 24 % indicated the critical level above which hypotension appeared commonly. The ANSindex value might help anesthesiologist to anticipate and prepare for hypotension that is likely to ensue.

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

    Full Text Available Topical anesthetics are being widely used in numerous medical and surgical sub-specialties such as anesthesia, ophthalmology, otorhinolaryngology, dentistry, urology, and aesthetic surgery. They cause superficial loss of pain sensation after direct application. Their delivery and effectiveness can be enhanced by using free bases; by increasing the drug concentration, lowering the melting point; by using physical and chemical permeation enhancers and lipid delivery vesicles. Various topical anesthetic agents available for use are eutectic mixture of local anesthetics, ELA-max, lidocaine, epinephrine, tetracaine, bupivanor, 4% tetracaine, benzocaine, proparacaine, Betacaine-LA, topicaine, lidoderm, S-caine patch™ and local anesthetic peel. While using them, careful attention must be paid to their pharmacology, area and duration of application, age and weight of the patients and possible side-effects.

    1987-01-01

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

    2003-10-01

    A 78-year-old male, observed for bronchial asthma, underwent two emergency operations within eight days. The first operation was performed under general anesthesia with tracheal intubation. Anesthesia was maintained by sevoflurane-oxygen and continuous infusion of propofol in combination with epidural injection of lidocaine. During the operation, respiratory sound was almost clear. But wheezing occurred as he awoke after discontinuation of the anesthetics. He needed ventilatory support for three days for status asthmatics. The second operation was performed under continuous spinal anesthesia using hypobaric tetracaine and hyperbaric bupivacaine. No ventilatory support was necessary after the operation and he was discharged uneventfully.

  11. Anesthesia for off-pump coronary artery bypass surgery

    Thomas M Hemmerling

    2013-01-01

    Full Text Available The evolution of techniques and knowledge of beating heart surgery has led anesthesia toward the development of new procedures and innovations to promote patient safety and ensure high standards of care. Off-pump coronary artery bypass (OPCAB surgery has shown to have some advantages compared to on-pump cardiac surgery, particularly the reduction of postoperative complications including systemic inflammation, myocardial injury, and cerebral injury. Minimally invasive surgery for single vessel OPCAB through a limited thoracotomy incision can offer the advantage of further reduction of complications. The anesthesiologist has to deal with different issues, including hemodynamic instability and myocardial ischemia during aorto-coronary bypass grafting. The anesthesiologist and surgeon should collaborate and plan the best perioperative strategy to provide optimal care and ensure a rapid and complete recovery. The use of high thoracic epidural analgesia and fast-track anesthesia offers particular benefits in beating heart surgery. The excellent analgesia, the ability to reduce myocardial oxygen consumption, and the good hemodynamic stability make high thoracic epidural analgesia an interesting technique. New scenarios are entering in cardiac anesthesia: ultra-fast-track anesthesia with extubation in the operating room and awake surgery tend to be less invasive, but can only be performed on selected patients.

This randomized double-blind trial compared the postoperative analgesic efficacy of PIEB with that of continuous epidural infusion (CEI in patients undergoing gynecological surgery under combined general-epidural anesthesia. Methods. Patients undergoing open gynecological surgery under combined general-epidural anesthesia were randomized at a 1 : 1 ratio to receive PIEB or CEI. In the PIEB group, the pump delivered 4 mL ropivacaine 0.2% plus fentanyl 2 μg/mL every hour. In the CEI group, the pump delivered the same solution at a rate of 4 mL/h. In both groups, additional 4 mL boluses of ropivacaine 0.2% plus fentanyl 2 μg/mL were provided, when necessary, by patient-controlled epidural analgesia after surgery. The primary outcome was the total ropivacaine dose 40 hours after surgery. The secondary outcomes were the number of PCEA boluses and postoperative pain (evaluated on an 11-point numerical rating scale 3, 24, and 48 hours after surgery. Results. In total, 57 patients were randomized (n=28 and 29 in the PIEB and CEI groups, resp.. The two groups differ significantly in terms of the total ropivacaine dose 40 hours after surgery (mean (standard deviation: 155.38 (4.55 versus 159.73 (7.87 mL, P=0.016. Compared to the CEI group, the PIEB group had significantly lower numerical rating scale scores 3 hours (median [lower–upper quartiles]: 0 [0–0.5] versus 3 [0–5.5], P=0.002, 24 hours (1 [0–2] versus 3 [1–4], P=0.003, and 48 hours (1 [0–2] versus 2 [2–3.5], P=0.002 after surgery. Conclusion. PIEB was better than CEI in terms of providing postoperative analgesia after open gynecological surgery under combined general-epidural anesthesia.

    Although epidural anesthesia is considered safe, several complications may occur during puncture and insertion of a catheter. Incidences of paresthesia vary between 0.2 and 56%. A prospective, open, cohort-controlled pilot study was conducted in 188 patients, ASA I-III, age 19-87 years, scheduled for elective surgery and epidural anesthesia. We evaluated a 20 G polyamide (standard) catheter and a 20 G combined polyurethane-polyamide (new) catheter. Spontaneous reactions upon catheter-insertion, paresthesia on questioning, inadvertent dural or intravascular puncture, and reasons for early catheter removal were recorded. The incidence of paresthesia reported spontaneously was 21.3% with the standard catheter and 16.7% with the new catheter. Systematically asking for paresthesia almost doubled the paraesthesia rate. Intravascular cannulation occurred in 5%. No accidental dural punctures occurred. An overall incidence of 13.3% of technical problems led to early catheter removal. The new catheter was at least equivalent to the standard regarding epidural success rate and safety : rate of paresthesia, intravascular and dural cannulation.

    Two healthy obese, seven-year-old, female Rottweilers weighing 40 and 57 kg were submitted for cranial cruciate repair. They were premedicated with intravenous methadone (0.1 mg kg(-1)) and acepromazine (0.01 and 0.02 mg kg(-1)). Anesthesia was induced with propofol (3.6 and 2.5 mg kg(-1)) and maintained with isoflurane in oxygen using a circle breathing system. The dogs were placed in sternal recumbency and epidural injection of lidocaine/bupivacaine or lidocaine/bupivacaine/morphine (0.2 mL/kg, 8 and 11 mL) was carried out over 1.5 and 4 minutes. Epidural pressures were 79 and 72 mmHg at the end of the injections. The first dog's heart rate decreased from 80 to 65 beats minute(-1) with a second degree atrioventricular (AV) block. The arterial pressure decreased from 100 to 50 mmHg. These responded to atropine (0.01 mg kg(-1) IV). The second dog's heart rate decreased from 120 to 60 beats minute(-1) while arterial pressure decreased from 72 to 38 mmHg. No treatment was given and heart rate and arterial blood pressure returned to acceptable ranges. These cases suggest that large increases in epidural pressure may cause significant cardiovascular effects. This may be avoided by using lower volumes and discontinuing injection if significant back pressure is detected.

    Systemic hypotension is a relatively common complication of preterm birth and is associated with periventricular haemorrhage, periventricular white matter injury and adverse neurodevelopmental outcome. Corticosteroid treatment has been used as an alternative or an adjunct to conventional treatment with volume expansion and vasopressor/inotropic therapy. To determine the effectiveness and safety of corticosteroids used either as primary treatment of hypotension or for the treatment of refractory hypotension in preterm infants. Randomized or quasi-randomised controlled trials were identified by searching the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 2, 2011), MEDLINE (1996 to Jan 2011), EMBASE (1974 to Jan 2011), CINAHL (1981 to 2011), reference lists of published papers and abstracts from the Pediatric Academic Societies and the European Society for Pediatric Research meetings published in Pediatric Research (1995 to 2011). We included all randomised or quasi-randomised controlled trials investigating the effect of corticosteroid therapy in the treatment of hypotension in preterm infants (babies with hypotension resistant to inotropes/pressors and volume therapy. We included studies comparing oral/intravenous corticosteroids with placebo, other drugs used for providing cardiovascular support or no therapy in this review. Methodological quality of eligible studies was assessed according to the methods used for minimising selection bias, performance bias, attrition bias and detection bias. Studies that evaluated corticosteroids (1) as primary treatment for hypotension or (2) for refractory hypotension unresponsive to prior use of inotropes/pressors and volume therapy, were analysed using separate comparisons. Data were analysed using the standard methods of the Neonatal Review Group using Rev Man 5.1.2. Treatment effect was analysed using relative risk, risk reduction, number needed to treat for categorical outcomes and

    This review of the historical course of anesthesia performed in the context of urology in Spain relies on primary sources: doctoral theses, dissertations, published articles, inaugural addresses, conference proceedings, and books belonging to various archives and libraries. We collected a large number of documents relating to urology and of particular interest regarding anesthesia, classified them, and subjected them to critical analysis. This allowed us to carefully follow the development of anesthesia and urology itself, both of which attained notable clinical and scientific importance in Spain. Anesthesia with chloroform and incomplete anesthesia were the norm during the second half of the 19th century. However, during the first half of the 20th century, the most widely used techniques were the application of ether or spinal or local infusions, although epidural and intravenous techniques were also mentioned.

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

    Cervical epidural anesthesia has been used widely for surgery of upper limbs. Although cervical epidural anesthesia with local anesthetic of 2% lidocaine (plain) has demonstrated the safety in respiratory function in spite of unavoidable phrenic and intercostal palsies to certain extent, the replacement of local anesthetics with 2% lidocaine plus epinephrine has not been investigated yet. I conducted this study to look into the effect of 2% lidocaine plus epinephrine on respiratory function. I collected data from 50 patients with mean age of 24 +/- 3 yrs, mean weight of 65 +/- 10 kg, ASA status: I-II without preoperative pulmonary dysfunction undergoing orthropedic open-reduction with internal fixation because of fractures of upper limbs. Cervical epidural space (C7-T1) was approached by hanging-drop method, using a 17G Tuohy needle. A catheter was inserted craniad to a distance of 12 cm. Pulmonary function measurement and arterial blood gas data were obstained before, 20 min, 50 min and 105 min after injection of 12 mL 2% lidocaine with 1:200,000 epinephrine. The anesthesia levels were between C3-T3 and obtained 15 +/- 2 min after injection. Mean arterial blood gas analysis showed mild respiratory acidosis at 20 min (PaCO2: 48 +/- 3 mmHg) and 50 min (PaCO2: 44 +/- 2 mmHg). The measured values of inspiratory vital capacity (IVC), vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in 1 sec (FEV1), peak expiratory flow (PEF) when compaired with control values, were decreased about 18.0% and 12.1% of the control values at 20 min and 50 min respectively. The ratios of FEV1/VC, FEV1/FVC were still within normal limits (> 80%). The results were significantly compatible with the criteria of mild restrictive type of pulmonary function. Cervical epidural anesthesia with 2% lidocaine plus epinephrine could reduce lung volumes and capacities, resulting from partially paralytic intercostal muscles and diaphragm innervated respectively by thoracic

  3. Analgesia/anesthesia for external cephalic version.

    2013-06-01

    Professional society guidelines recommend that women with breech presentation be delivered surgically due to a higher incidence of fetal risks compared with vaginal delivery. An alternative is attempted external cephalic version, which if successful, enables attempted vaginal delivery. Attitudes towards external cephalic version (ECV) will be considered in this review, along with pain relief methods and their impact on ECV success rates. Articles suggest that ECV is infrequently offered, due to both physician and patient factors. Success of ECV is higher in multiparous women, complete breech, posterior placenta, or smaller fetus. Preterm ECV performance does not increase vaginal delivery rates. Neuraxial techniques (spinal or epidural) significantly increase ECV success rates, as do moxibustion and hypnosis. Four reviews summarized studies considering ECV and neuraxial techniques. These reviews suggest that neuraxial techniques using high (surgical) doses of local anesthetic are efficacious compared with control groups not using anesthesia, whereas techniques using low-doses are not. Low-dose versus high-dose neuraxial analgesia/anesthesia has not been directly compared in a single study. Based on currently available data, the rate of cephalic presentation is not increased using neuraxial techniques, but vaginal delivery rates are higher. ECV appears to be a low-risk procedure. The logistics of routine ECV and provision of optimal neuraxial techniques for successful ECV require additional research. Safety aspects of neuraxial anesthesia for ECV require further investigation.

    Full Text Available Purpose. Failed back surgery syndrome is a chronic pain condition requiring rapid, effective, and efficient management. This study evaluates the effect of adding dexmedetomidine to lumbar epidural steroids in patients with failed back surgery syndrome. Methods. Fifty patients suffering from failed back surgery syndrome were randomly assigned to one of two groups, receiving an epidural injection of 20 mL of either a mixture of betamethasone (14 mg and bupivacaine 0.5 mg (group C or a mixture of betamethasone (14 mg, bupivacaine 0.5 mg, and dexmedetomidine (0.5 μg/kg (group D adjusted to the volume with normal saline. The effect was evaluated using visual analogue scale (VAS, analgesic requirement, and Oswestry disability index 2 weeks, 4 weeks, 8 weeks, and 12 weeks after injection. Results. VAS and ibuprofen consumption showed a significant reduction in group D. The Oswestry disability index was significantly improved in group D. There were no records of hypotension, bradycardia, sedation, or hypoxemia in both groups. Conclusion. The present study demonstrated potential safe and effective usage of adding dexmedetomidine to epidural steroid to control pain in patients with failed back surgery syndrome.

    2007-06-01

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

    This study involved a retrospective evaluation of patients subjected to surgery for dentofacial deformities treated without induced controlled hypotension (group I, n=50) and a prospective evaluation of patients who were subjected to surgery under hypotensive general anaesthesia (group II, n=50). No statistical differences were found between the study groups with regard to the duration of surgery. However, there were statistically significant differences in the need for blood transfusion and the occurrence of bradycardia during the maxillary down-fracture. Hypotensive anaesthesia decreased the need for a blood transfusion and the occurrence of bradycardia, and is therefore considered highly beneficial for patients undergoing orthognathic surgery.

    Full Text Available Purpose: To report a case of temporary bilateral corneal denting in a patient who underwent cardiovascular surgery under general anesthesia. Observations: A 71-year-old male with no history of ophthalmological disease experienced bilateral corneal denting immediately after undergoing surgery for aneurysm of the thoracic aorta under general anesthesia. Anesthesia was induced with propofol and maintained with rocuronium bromide and remifentanil hydrochloride. The initial examination revealed significant denting on the surface of both the corneas and ocular hypotension. Visual evaluation could not be performed due to the patient's low level of consciousness resulting from delayed emergence from anesthesia. After applying tropicamide and phenylephrine ophthalmic solution for fundus examination, the ocular morphology improved. Ocular pressure was normal on the day after surgery, and creasing on the surface of the corneas had disappeared. Conclusions: and Importance: We experienced a patient with bilateral corneal denting following a cardiovascular surgery under general anesthesia. The dents could be attributed to augmentation of ocular hypotension using several types of anesthesia at relatively high doses.

    1998-01-01

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

    2017-06-01

    Clinical presentation of spontaneous intracranial hypotension headache (SIHH) has similarities with postdural puncture headache (PDPH). Recommended treatment for both conditions is an epidural blood patch. Successful outcomes following greater occipital nerve blocks have been reported in the management of PDPH. We present the first report of greater occipital nerve treatment in SIHH. A 40-year-old male presented with a 2-year history of daily postural headaches having a significant impact on quality of life. Magnetic resonance imaging revealed bilateral convexity subdural collections. Post gadolinium scan revealed pachymeningeal enhancement with reduced pontomesencephalic angle below 50 degrees. The patient was offered an epidural blood patch and greater occipital nerve block with corticosteroids. The patient chose occipital nerve block. The patient reported significant short-term benefit lasting 4 months. Thereafter, the patient underwent pulsed radiofrequency treatment to bilateral greater occipital nerves. He reported significant benefit lasting 10 months. Greater occipital nerve treatment may have a role in management of SIHH. © 2017 American Headache Society.

    In patients operated for cerebral aneurysm or angioma, the same basic method of anesthesia has been used. Premedication consisted of Thalamonal or diazepam. After induction with thiopentone, curarisation with pancuronium and tracheal intubation, anesthesia was maintained with N2O 70%, O2 30% and enflurane 1%. Small doses of fentanyl or Thalamonal were given at the beginning of anesthesia, but no more within 30 minutes before starting controlled hypotension. Adjuvant drugs and methods to reduce intracranial pressure were also used, such as dexamethasone, mannitol and cerebro-spinal fluid subtraction. The approach and dissection of the vascular lesion was done under controlled hypotension with sodium nitroprusside 0.01% solution. The mean dose of sodium nitroprusside to maintain a mean blood pressure at about 50 Torr was 1.37 mcg/kg/min.

    Major strides in the molecular biology of essential hypertension are currently underway. This has tended to obscure the fact that a number of inherited disorders associated with low blood pressure exist and that these diseases may have milder and underrecognized phenotypes that contribute importantly to blood pressure variation in the general population. This review highlights some of the gene products that, if abnormal, could cause hypotension in some individuals. Diseases due to abnormalities in the catecholamine enzymes are discussed in detail. It is likely that genetic abnormalities with hypotensive phenotypes will be as interesting and diverse as those that give rise to hypertensive disorders.

    Although music is frequently used to promote a relaxing environment during labor and delivery, the effect of its use during the placement of neuraxial techniques is unknown. Our study sought to determine the effects of music use on laboring parturients during epidural catheter placement, with the hypothesis that music use would result in lower anxiety, lower pain, and greater patient satisfaction. We conducted a prospective, randomized, controlled trial of laboring parturients undergoing epidural catheter placement with or without music. The music group listened to the patient's preferred music on a Pandora® station broadcast through an external amplified speaker; the control group listened to no music. All women received a standardized epidural technique and local anesthetic dose. The primary outcomes were 3 measures of anxiety. Secondary outcomes included pain, patient satisfaction, hemodynamic parameters, obstetric parameters, neonatal outcomes, and anesthesia provider anxiety. Intention-to-treat analysis with Bonferroni correction was used for the primary outcomes. For secondary outcomes, a P value of music group, the duration of music use was 31.1 ± 7.7 minutes (mean ± SD). The music group experienced higher anxiety as measured by Numeric Rating Scale scores immediately after epidural catheter placement (2.9 ± 3.3 vs 1.4 ± 1.7, mean difference 1.5 [95% confidence interval {CI} 0.2-2.7], P = .02), and as measured by fewer parturients being "very much relaxed" 1 hour after epidural catheter placement (51% vs 78%, odds ratio {OR} 0.3 [95% CI 0.1-0.9], P = .02). No differences in mean pain scores immediately after placement or patient satisfaction with the overall epidural placement experience were observed; however, the desire for music use with future epidural catheter placements was higher in the music group (84% vs 45%, OR 6.4 [95% CI 2.5-16.5], P Music use during epidural catheter placement in laboring parturients is associated with higher postprocedure

    We investigated the effects of the beach-chair position and induced hypotension on regional cerebral oxygen saturation (rSO(2)) in patients undergoing arthroscopic shoulder surgery by using near-infrared spectroscopy. Twenty-eight patients scheduled for arthroscopic shoulder surgery were enrolled prospectively. After induction of anesthesia, mechanical ventilation was controlled to maintain Paco(2) at 35 to 40 mm Hg. Anesthesia was maintained with sevoflurane and remifentanil. After radial artery cannulation, mean arterial pressure (MAP) was measured at the external auditory meatus level and maintained between 60 and 65 mm Hg. The rSO(2) was measured by use of near-infrared spectroscopy. MAP and rSO(2) were recorded at the following times: before induction (T(0)), immediately after induction (T(1) [baseline]), after beach-chair position (T(2)), immediately after induced hypotension (T(3)), 1 hour after induced hypotension (T(4)), and after supine position at the end of surgery (T(5)). Cerebral desaturation was defined as a reduction in rSO(2) to less than 80% of baseline value for 15 seconds or greater. A total of 27 patients were evaluated until the end of this study. The MAP at T(2) was significantly lower than that at T(1). The MAP values at T(3) and T(4) were significantly lower than those at T(1) and T(2). The rSO(2) at T(2) was significantly lower than that at T(1). Unlike the pattern of change in the MAP, there was no additional decrease in rSO(2) at T(3) and T(4). There were 2 patients who had an episode of cerebral desaturation. The beach-chair position combined with induced hypotension significantly decreases rSO(2) in patients undergoing shoulder arthroscopic surgery under general anesthesia.

    To evaluate the accuracy of epidural catheter placement at different levels of the spinal cord guided solely by electrical nerve stimulation and resultant segmental muscle contraction. Prospective, experiment. Six male and two female Beagles, age (1 ± 0.17 years) and weight (12.9 ± 1.1 kg). Animals were anesthetized with propofol and maintained with isoflurane. An insulated epidural needle was used to reach the lumbosacral epidural space. A Tsui epidural catheter was inserted and connected to a nerve stimulator (1.0 mA, 0.1 ms, 2 Hz) to assess positioning of the tip at specific spinal cord segments. The catheter was advanced to three different levels of the spinal cord: lumbar (L2-L5), thoracic (T5-T10) and cervical (C4-C6). Subcutaneous needles were previously placed at these spinal levels and the catheter was advanced to match the needle location, guided only by corresponding muscle contractions. Catheter position was verified by fluoroscopy. If catheter tip and needle were at the same vertebral body a score of zero was assigned. When catheter tip was cranial or caudal to the needle, positive or negative numbers, respectively, corresponding to the number of vertebrae between them, were assigned. The mean and standard deviation of the number of vertebrae between catheter tip and needle were calculated to assess accuracy. Results are given as mean ± SD. The catheter position in relation to the needle was within 0.3 ± 2.0 vertebral bodies. Positive predictive values (PPV) were 57%, 83% and 71% for lumbar, thoracic and cervical regions respectively. Overall PPV was 70%. No significant difference in PPV among regions was found. Placement of an epidural catheter at specific spinal levels using electrical nerve stimulation was feasible without radiographic assistance in dogs. Two vertebral bodies difference from the target site may be clinically acceptable when performing segmental epidural regional anesthesia. © 2013 Association of Veterinary

    Background Awake regional anesthesia (RA) is a viable alternative to general anesthesia (GA) for infants undergoing lower abdominal surgery. Benefits include lower incidence of postoperative apnea and avoidance of anesthetic agents that may increase neuroapoptosis and worsen neurocognitive outcomes. The General Anesthesia compared to Spinal anesthesia (GAS) study compares neurodevelopmental outcomes following awake RA or GA in otherwise healthy infants. Our aim was to describe success and failure rates of RA in this study and report factors associated with failure. Methods This was a nested cohort study within a prospective randomized, controlled, observer blind, equivalence trial. Seven hundred twenty two infants ≤ 60 weeks postmenstrual age, scheduled for herniorrhaphy under anesthesia were randomly assigned to receive RA (spinal, caudal epidural or combined spinal caudal anesthetic) or GA with sevoflurane. The data of 339 infants, where spinal or combined spinal caudal anesthetic was attempted, was analyzed. Possible predictors of failure were assessed including: patient factors, technique, experience of site and anesthetist and type of local anesthetic. Results RA was sufficient for the completion of surgery in 83.2% of patients. Spinal anesthesia was successful in 86.9% of cases and combined spinal caudal anesthetic in 76.1%. Thirty four patients required conversion to GA and an additional 23 (6.8%) required brief sedation. Bloody tap on the first attempt at lumbar puncture was the only risk factor significantly associated with block failure (OR = 2.46). Conclusions The failure rate of spinal anesthesia was low. Variability in application of combined spinal caudal anesthetic limited attempts to compare the success of this technique to spinal alone. PMID:26001028

    Laparoscopic cholecystectomy became the standard surgery for gallstone disease because of causing less postoperative pain, respiratory compromise and early ambulation. This study was designed to compare spinal anesthesia, (segmental thoracic or conventional lumbar) vs the gold standard general anesthesia as three anesthetic techniques for healthy patients scheduled for elective laparoscopic cholecystectomy, evaluating intraoperative parameters, postoperative recovery and analgesia, complications as well as patient and surgeon satisfaction. A total of 90 patients undergoing elective laparoscopic cholecystectomy, between January 2010 and May 2011, were randomized into three equal groups to undergo laparoscopic cholecystectomy with low-pressure CO2 pneumoperitoneum under segmental thoracic (TSA group) or conventional lumbar (LSA group) spinal anesthesia or general anesthesia (GA group). To achieve a T3 sensory level we used (hyperbaric bupivacaine 15 mg, and fentanyl 25 mg at L2/L3) for LSAgroup, and (hyperbaric bupivacaine 7.5 mg, and fentanyl 25 mg at T10/T11) for TSAgroup. Propofol, fentanyl, atracurium, sevoflurane, and tracheal intubation were used for GA group. Intraoperative parameters, postoperative recovery and analgesia, complications as well as patient and surgeon satisfaction were compared between the three groups. All procedures were completed laparoscopically by the allocated method of anesthesia with no anesthetic conversions. The time for the blockade to reach T3 level, intraoperative hypotensive and bradycardic events and vasopressor use were significantly lower in (TSA group) than in (LSA group). Postoperative pain scores as assessed throughout any time, postoperative right shoulder pain and hospital stay was lower for both (TSA group) and (LSA group) compared with (GA group). The higher degree of patients satisfaction scores were recorded in patients under segmental TSA. The present study not only confirmed that both segmental TSA and conventional

In both groups, intravenous injection of midazolam, propofol, fentanyl, and atracurium besilate was given to induce anesthesia, and propofol, fentanyl, atracurium besilate, together with sevoflurane inhalation were used to maintain anesthesia. The radial artery was cannulated to monitor the invasive mean arterial pressure (MAP. Controlled hypotension was induced by adjusting the sevoflurane concentration in group Ⅰ. In group Ⅱ, within 15min to 30min before the induction of anesthesia, dexmedetomidine was administered in a dose of 0.8μg/kg via intravenous infusion pump, then maintained at 0.4μg/(kg·h. Sevoflurane concentration was adjusted to maintain the target blood pressure at the beginning of surgery. The MAP was maintained at 65-75mmHg up to the end of operation.

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

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

    Full Text Available Background: Previous studies have revealed that QTc interval is prolonged in pre-eclamptic parturients. Another study reflected the relationship between the sympathetic block and QTc interval. Subarachnoid block was safely administered in patients with severe pre-eclampsia. It has also been noticed that hypotension in response to spinal anesthesia is relatively less in pre-eclamptic patients than normal parturients. Aim: To compare the QTc values in normal and pre-eclamptic term parturients and to establish whether any correlation exists between the QTc interval and the systemic hypotension following subarachnoid block. Materials and Methods: Twenty-five pre-eclamptic patients (Group A and 25 normotensive patients (Group B were included in this study. QTc interval was recorded for each patient before subarachnoid block for cesarean section. Changes in arterial blood pressure and heart rate were measured in both the groups and compared. Results: Baseline QTc was significantly higher in the pre-eclamptic group (Group A: 0.47 ± 0.11 with that of control (Group B: 0.36. ± 0.02. Significant fall in blood pressure was seen only in one group with QTc between 0.38 and 0.39 in Group A. Hypotension was significantly more in normotensive mothers (Group B. However, no statistical correlation could be drawn from this study between QTc interval and hypotension, although a trend toward increasing hypotension with decreasing QTc was present. Discussion : The prolonged QTc intervals seen in pre-eclamptic patients may be due to the contributory effects of sympathetic hyperactivity, hypertension, and hypocalcemia secondary to underlying vasoconstriction. Decreased vagal control of heart in pre-eclampsia may have produced the difference in change in hemodynamic status between pre-eclamptic and normotensive parturient. Conclusion: Any consistent correlation between QTc and hypotension following subarachnoid block could not be derived from this study. To achieve a

    Background and objectives

     Provision of standard childbirth facilities has been considered as an important healthcare issue for a long time. The physical and psychological states of mothers are important factors determining the fate of delivery. Therefore, several programs have been established to decrease the mother-child mortality rates and the complications of delivery. One of the most common approaches for controlling the pain of delivery is application of local anesthesia such as epidural, spinal, or a combination of these methods. It has been shown that complications of epidural anesthesia are less than other methods of local anesthesia employed for the painless delivery. In this study, a comparison is made between two groups of 80 neonates delivered by either NVD or EU.

    Methods

     A form was designed for collection of data including Apgar score at first minute, need for CPR, NICU admission, FHR variability, breast feeding time, duration of hospital stay, and neonatal reflexes. The data were analyzed by chi-square and fisher tests using SPSS software.

    Results

     There was no significant difference between the neonates born by EA or NVD at the 95% confidence level.

    Conclusion

     Based on these findings it could be concluded that epidural anesthesia for delivery does not lead to neonatal complications more than that of NVD without pain control. Therefore, this method could be recommended to mothers, who choose elective cesarean section to avoid the pain of childbirth.

    As in adult anesthesia, morbidity and mortality could be significantly reduced in pediatric anesthesia in recent decades. This fact cannot conceal the fact that the incidence of anesthetic complications in children is still much more common than in adults and sometimes with a severe outcome. Newborns and infants in particular but also children with emergency interventions and severe comorbidities are at increased risk of potential complications. Typical complications in pediatric anesthesia are respiratory problems, medication errors, difficulties with the intravenous puncture and pulmonal aspiration. In the postoperative setting, nausea and vomiting, pain, and emergence delirium can be mentioned as typical complications. In addition to the systematic prevention of complications in pediatric anesthesia, it is important to quickly recognize disturbances of homeostasis and treat them promptly and appropriately. In addition to the expertise of the performing anesthesia team, the institutional structure in particular can improve quality and safety in pediatric anesthesia.

    and the widespread use of the term "stress free anesthesia" in surgery is therefore not valid. However, continuous administration of local anesthetic agents in the epidural space is the most effective technique in so far as reduction of the stress response is concerned. The clinical implication of a variable...... reduction in the stress response to surgery by different anesthetic techniques remains largely unsettled, since only few controlled studies have been published on the clinical effects of pain relief and general anesthesia.

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

In addition, a major obstacle to acceptance of this technology is the concern of users over the impact of the electronic anesthesia...

  17. Perioperative Vasovagal Syncope with Focus on Obstetric Anesthesia

    Directory of Open Access Journals (Sweden)

    Pei-Shan Tsai

    2006-09-01

    Full Text Available Vasovagal syncope refers to a reflex cardiovascular depression that gives rise to loss of consciousness with bradycardia and profound vasodilatation. This response commonly occurs during regional anesthesia, hemorrhage or supine inferior vena cava compression in pregnancy. The changes in circulatory response from the normal maintenance of arterial pressure to parasympathetic activation and sympathetic inhibition may cause severe hypotension. This change is triggered by reduced cardiac venous return as well as episodes of emotional stress, excitement or pain. Occasionally, these vasovagal responses may be unpredictable and may dramatically proceed to asystole with circulatory collapse, and may even result in death. In these circumstances, hypotension may be more severe than that caused by bradycardia alone, because of unappreciated vasodilatation. Regional anesthesia, decreased venous return, hemorrhage and abnormal fetal presentation cumulatively increase the risk of vasovagal syncope in cesarean section patients. When a vasovagal response occurs, ephedrine is the drug of first choice because of its combined action on the heart and peripheral blood vessels. Epinephrine must be used early in established cardiac arrest, especially after high regional anesthesia.

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

    Ciguatera results when ciguatoxin-contaminated coral reef fish from tropical or subtropical waters are consumed. The clinical features that present in affected persons are mainly gastrointestinal, neurological, general, and much less commonly, cardiovascular. We report the case of a 50-year-old man who developed the characteristic combination of acute gastrointestinal and neurological symptoms after the consumption of an unidentified coral reef fish head. In addition to those symptoms, he developed dizziness, severe bradycardia (46 bpm) and prolonged hypotension, which required the administration of intravenous atropine and over three days of intravenous fluid replacement with dopamine infusion. Patients with ciguatera can develop severe bradycardia and prolonged hypotension. Physicians should recognise the possible cardiovascular complications of ciguatera and promptly initiate treatment with intravenous atropine, intravenous fluid replacement and inotropic therapy if such complications are observed.

    To evaluate brain MRI findings of spontaneous intracranial hypotension. A retrospective review of MRI findings was conducted on six patients with clinically proven spontaneous intracranial hypotension; no patient had a history of previous spinal puncture. Follow-up MRI was available in two patients, and to detect CSF leakage, radio-nuclide cisternography(n=3D5), myelography(n=3D1), and MR myelography(n=3D1) were performed. On contrast-enhanced T1WI, diffuse dural enhancement was seen in all cases, subdural hematoma or hygroma was seen in four cases, pituitary gland prominence in four, dural sinus dilatation in four, downward displacement of the cerebellar tonsil in two, downward displacement of the iter in one, and suprasellar and prepontine cistern effacement in two. In no patient was abnormal CSF leakage found. Although dural enhancement, as seen on MRI, is not specific, diffuse enhancement of the dura mater accompanied by subdural hematoma, hygroma, pituitary gland prominence, dural sinus dilatation, downward displacement of the cerebellar tonsil, or suprasellar and prepontine cistern effacement can strongly suggest intracranial hypotension.=20.

    Intestinal transplantation is a complex and challenging surgery. It is very effective for treating intestinal failure, especially for those patients who cannot tolerate parenteral nutrition nor have extensive abdominal disease. Chronic parental nutrition can induce intestinal failure associated liver disease (IFALD). According to United Network for Organ Sharing (UNOS) data, children with intestinal failure affected by liver disease secondary to parenteral nutrition have the highest mortality on a waiting list when compared with all candidates for solid organ transplantation. Intestinal transplant grafts can be isolated or combined with the liver/duodenum/pancreas. Organ Procurement and Transplantation Network (OPTN) has defined intestinal donor criteria. Living donor intestinal transplant (LDIT) has the advantages of optimal timing, short ischemia time and good human leukocyte antigen matching contributing to lower postoperative complications in the recipient. Thoracic epidurals provide excellent analgesia for the donors, as well as recipients. Recipient management can be challenging. Thrombosis and obstruction of venous access maybe common due to prolonged parenteral nutrition and/or hypercoaguability. Thromboelastography (TEG) is helpful for managing intraoperative product therapy or thrombosis. Large fluid shifts and electrolyte disturbances may occur due to massive blood loss, dehydration, third spacing etc. Intestinal grafts are susceptible to warm and cold ischemia and ischemia-reperfusion injury (IRI). Post-reperfusion syndrome is common. Cardiac or pulmonary clots can be monitored with transesophageal echocardiography (TEE) and treated with recombinant tissue plasminogen activator. Vasopressors maybe used to ensure stable hemodynamics. Post-intestinal transplant patients may need anesthesia for procedures such as biopsies for surveillance of rejection, bronchoscopy, endoscopy, postoperative hemorrhage, anastomotic leaks, thrombosis of grafts etc. Asepsis

    Labor is one of the most painful experiences a woman may face during her lifetime. One of the most effective methods used for eliminating this pain is epidural analgesia. The aim of this study to determine the impact of adding morphine to low-dose bupivacaine epidural anesthesia on labor and neonatal outcomes, and maternal side effects. This is a prospective randomized double-blind study comparing two regimens of anesthetic agents used for epidural anesthesia in labor. A total of 120 pregnant women were randomized into two groups with 60 subjects in each study arm. A catheter was inserted, and 0.1% bupivacaine + 2 μg/mL fentanyl in 15 mL saline were given to Group bupivacaine-fentanyl (Group BF), while 0.0625% bupivacaine + 2 μg/ml fentanyl + 2 mg morphine in 15 mL saline were given to Group bupivacaine-fentanyl-morphine (Group BFM) with no test dosing from the needle. No morphine was added to the subsequent epidural injections in Group BFM. The total dose of bupivacaine was significantly lower in Group BFM relative to Group BF (P = 0.0001). The visual analogu scalescores at 15, 30, and 45 min were significantly lower in Group BF compared to thosein Group BFM (P = 0.0001, P = 0.001, and P = 0.006, respectively). The second stage of labor was significantly shorter in Group BFM relative to Group BF (P = 0.027 and P = 0.003, respectively). The satisfaction with analgesia following the first dose was higher in the nonmorphine group (P = 0.0001). However, maternal postpartum satisfaction was similar in both groups. Either nausea or vomiting was recorded in eight patients in Group BFM. We believe that epidural analgesia comprised of a low-dose local anaesthetic and 2 mg morphine provides a painless labor that significantly reducesthe use of local anesthetic without changing the efficiency of the analgesic, ensuring the mother's satisfaction without leading to an adverse effect on the mother or foetus, while mildly (but significantly) shortening the second stage of

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

  10. Fluoroscopically guided tunneled trans-caudal epidural catheter technique for opioid-free neonatal epidural analgesia.

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

    The recent introduction of intraosseous injection devices has renewed interest in the modality of local anesthesia. Three devices currently available are the Stabident System, the Hypo Brand Intraosseous Needle, and the Cyberjet System. The Stabident System is the most popular and the only one for which published research is available. Primary intraosseous anesthesia is 45 percent to 93 percent effective but of short duration. Supplemental intraosseous anesthesia is 80 percent to 90 percent effective and provides profound anesthesia of long duration (60 minutes or longer). It is used when a prior conventional infiltration or nerve block is inadequate. During use of an anesthetic solution with a vasoconstrictor for intraosseous anesthesia, 46 percent to 100 percent of patients reported an increase in heart rate. There was a 2 percent to 27 percent incidence of moderate and sometimes severe pain during the intraosseous procedure. Postoperative complications occurred in 2 percent to 15 percent of patients and lasted one to 14 days.

    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

    The sitting beach-chair position is regularly used for shoulder surgery and anesthesia may be induced in that position. We tested the hypothesis that the cardiovascular challenge induced by induction of anesthesia is attenuated if the patient is placed in a reclining beach-chair position....... Anesthesia was induced with propofol in the sitting beach-chair (n = 15) or with the beach-chair tilted backwards to a reclining beach-chair position (n = 15).

Magnetic resonance imaging (MRI is the most comprehensive imaging modality of the spine, allowing for the accurate determination of tissue spaces and distances. The present study uses MRI-derived measurements to measure the SED and define the ratio between the straight and inclined SEDs at two thoracic levels (T6–7 and T9–10 in children.Methods: The T2-weighed sagittal MRI images of 109 children, ranging in age from 1 month to 8 years, undergoing radiological evaluation unrelated to spine pathology were assessed. The SEDs (inclined and straight were determined, and a comparison between the SEDs at two thoracic levels (T6–7 and T9–10 was made. Univariate and multivariate linear regression models were used to assess the relationship of the inclined thoracic T6–7 and T9–10 SED measurements with age, height, and weight.Results: Body weight demonstrated a stronger association with the SED than did the age or height with R2 values of 0.6 for T6–7 and 0.5 for T9–10. The formulae describing the relationship between the weight and the inclined SED were T6–7 inclined (mm = 7 + 0.9 × kg and T9–10 inclined (mm = 7 + 0.8 × kg.Conclusion: The depth of the pediatric thoracic epidural space shows a stronger correlation with weight than with age or height. Based on the MRI data, the predictive weight-based formulas can serve as guide to clinicians for placement of thoracic epidural catheters. Keywords: thoracic epidural space

    Full Text Available The aim of this study was to evaluate the pre-emptive effect of epidural ketamine S (+ (SK or racemic ketamine (RK administration, in post-incisional pain in horses. Were used in a blinded, randomized experimental study, sixteen mixed breed mares, 6±2 years old, weighting 273.2±42.0 kg. An epidural catheter was inserted 24 hours before the trials. The thigh region was shaved bilaterally, and mechanical cutaneous sensibility was measured using von Frey filaments (T-30. Using the left side as the control one, local anesthesia was performed at the right side. Twenty-five minutes later, SK was injected in G1 or RK in G2 through the epidural catheter. Five minutes after the ketamine injection, a 10 cm skin incision was made on the right side, and then sutured. Mechanical post-incisional pain was measured using von Frey filaments, at 1, 3 and 5 cm around the incision at 15 minutes intervals, for 2 hours, then 4, 6 and 8 hours after suturing. No changes were observed in the heart and respiratory rate and rectal temperature among groups or times of each group. Hind limb ataxia was observed in 62.5% and 12.5% of G1 and G2 respectively. SK and RK reduced cutaneous sensibility in the right and the left sides to mechanical postincisional pain during all time of experiment. Epidural SK and RK produce similar post-incisional analgesic effects, did not interfere in the cardio-respiratory parameters. The SK induces more intense ataxia in mares and presents a larger analgesic potency in the first 60 minutes after the administration.

The present study was aimed to compare the hemodynamic, sedative, and analgesia potentiating effects of dexmedetomidine versus fentanyl with epidural 0.5% levobupivacaine for vaginal hysterectomy. Patients and Methods: Sixty consented females of ASA physical status I and II aged 35-65 years weighing 55-75 kg, were double blindly randomized into two treatment groups. Patients received epidural 0.5% levobupivacaine 15 ml either with of 25 μg dexmedetomidine (Group LD or 50 μg fentanyl (Group LF and the total volume of study solution was kept 16 ml. Onset of analgesia at T10, sensory and motor block levels and duration of analgesia were observed. Intra-operatively, they were assessed for sedation, hemodynamic changes, respiratory efficiency, and side effects. The data obtained, was compiled systematically and analyzed statistically using Chi-square test and ANOVA. Value of P < 0.05 is considered significant. Result: The demographic profile was comparable between groups. The onset of sensory analgesia at T10 (7.25 ± 2.3 versus 9.27 ± 2.79 min and time to achieve complete motor blockade (19.27 ± 4.7 versus 22.78 ± 5.57 min was significantly earlier in patients of LD Group. The intraoperative hemodynamic changes were comparable between groups. Ramsey Sedation score was better in LD group with statistically significance. Postoperative analgesia was significantly prolonged in LD Group. Incidence of nausea, vomiting, and pruritus was high in LF group. Conclusion: Dexmedetomidine was better than fentanyl as an epidural adjuvant for providing early onset of sensory analgesia, adequate sedation with no respiratory depression and prolonged postoperative analgesia.

    Intracranial hypotension syndrome (IHS) is generally caused by cerebrospinal fluid (CSF) leakage. Complications include bilateral subdural hygroma or haematoma and herniation of the cerebellar tonsils. Epidural blood patch (EBP) therapy is indicated if conservative treatment is ineffective. We reported the case of a 46-year-old man with a history of postural headache and dizziness. The patient was treated with bed rest and daily hydration with 2000 mL of fluid for 2 weeks. However, dizziness and headache did not resolve, and he became drowsy and disoriented with incomprehensible speech. Magnetic resonance imaging demonstrated diffuse dural enhancement on the postcontrast study, sagging of the midbrain, and CSF leakage over right lateral posterior thecal sac at C2 level. We performed EBP at the level of T10-T11. We injected 14 mL of autologous blood slowly in the Trendelenburg position. Within 30 minutes, he became alert and oriented to people, place, and time. We chose thoracic EBP as first line treatment in consideration of the risk of cervical EBP such as spinal cord and nerve root compression or puncture, chemical meningitis. Also we put our patient in Trendelenburg position to make blood travel towards the site of the leak. Untreated IHS may delay the course of resolution and affect the patient's consciousness. Delivery of EBP via an epidural catheter inserted from the thoracic spine is familiar with most of anesthesiologists. It can be a safe and effective treatment for patients with IHS caused by CSF leak even at C2.Key words: Anaesthetic techniques, regional, thoracic; cerebrospinal fluid leakage; epidural blood patch; heavily T2-weighted magnetic resonance myelography; intracranial hypotension syndrome; Trendelenburg position.

    Epidural analgesia has become the standard of care for knee replacement surgeries worldwide. Bupivacaine has been used successfully for many years. Epidural ropivacaine is now being used increasingly and seems to have benefits other than just pain relief, in terms of a better safety profile. To compare the efficacy of bupivacaine 0.125% (Group B) versus two concentrations of ropivacaine 0.1% (Group R1) and 0.2% (Group R2), in terms of pain scores, requirement of rescue analgesia, related adverse effects, and duration of postoperative (PO) hospital stay. A retrospective study was conducted from the acute pain service data of patients who underwent joint replacement surgeries in one or both limbs, over a span of 6 months. Patients were allocated to and analyzed under one of the three groups based on the drug concentration used postoperatively by epidural infusion. Data retrieved were demographic data, daily average visual analog scale (VAS) pain scores, rescue analgesia given, adverse effects, and PO hospital stay days for all three groups. Demographic data were comparable between the three groups. Daily average VAS pain scores on days 1 and 2 were significantly higher in Group R1. Groups B and R2 were comparable. There was significantly more requirement of rescue analgesia in Group R1 on day 1. Day 2 showed no significant difference in rescue analgesic requirement in all three groups. Days of PO hospital stay were significantly higher in Group R1. Adverse effects such as hypotension and delayed motor block were higher in Group B. Ropivacaine 0.2% and bupivacaine 0.125% were equally efficacious in terms of VAS pain scores, rescue analgesic requirement, and duration of PO hospital stay, but ropivacaine had a better safety profile in terms of less hypotension and lesser motor block.

Appeared in them: normal cardiotocographic records during childbirth, use of epidural associated with fentanyl, termination by vacuum and elevated temperature in one case.ObjectivesKnow if the neonatal adaptation to extrauterine life may be influenced by the use of epidural analgesia in childbirth. Review what role can have the rise in maternal temperature and the use of epidural fentanyl with the appearance of newborn respiratory distress.MethodsLiterature Review conducted in February of 2012 in Pubmed and the Cochrane Library, using the key words: childbirth, epidural analgesia, neonatal respiratory depression.ResultsOn the respiratory depression associated with fentanyl, a Cochrane review found indicating that newborns of mothers with an epidural, had a lower pH and were less need for administration of naloxone.On PubMed we find a review study that indicates that the respiratory depression caused by the administration of opioids via neuroaxial is rare, placing it below 1 per 1000, and a clinical case that concluded that doses of fentanyl exceeding 300 µg (approx. 5 µg/kg for 4 hours previous to childbirth, have a high risk of neonatal respiratory depression at birth.The same Cochrane review indicates that the women with epidural analgesia had increased risk of maternal fever of at least 38 ° C and a recent cohort study relates this increase in temperature with a greater likelihood of neonatal adverse events (from 37.5 ° C.ConclusionsThe studies found considered safe epidurals to the neonate and the mother, except when certain conditions are met. The literature and our clinical experience have been reports linking neonatal respiratory depression with increasing temperature (37

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

    A 46-year-old man, with a history of atopic dermatitis and bronchial asthma, underwent surgery for an inguinal hernia. Forty-three minutes subsequent to spinal anesthesia, the patient complained suddenly of dyspnea with wheezing. Blood pressure decreased and skin eruption was observed on his chest. Postoperative laboratory tests revealed high IgE concentration, and a skin test confirmed an allergy to latex. The patient's allergic reaction was easily overlooked because of his history of bronchial asthma and the possibility that the hypotension was caused by the high spinal anesthesia. Latex allergy should be considered in any suspicious case presenting with these symptoms during surgery. After recovery, a skin test should be used to confirm the allergy to avoid repeated allergic episodes.

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

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

    2012-02-01

    BACKGROUND: Ward-based patient-controlled epidural analgesia (PCEA) for postoperative pain control was introduced at our institution in 2006. We audited the efficacy and safety of ward-based PCEA from January 2006 to December 2008. METHOD: Data were collected from 928 patients who received PCEA in general surgical wards for postoperative analgesia using bupivacaine 0.125% with fentanyl 2 mug\\/mL. RESULTS: On the first postoperative day, the median visual analogue pain score was 2 at rest and 4 on activity. Hypotension occurred in 21 (2.2%) patients, excessive motor blockade in 16 (1.7%), high block in 5 (0.5%), nausea in 5 (0.5%) and pruritus in only 1 patient. Excessive sedation occurred in two (0.2%) patients but no intervention was required. There were no serious complications such as epidural abscess, infection or haematoma. CONCLUSION: Effective and safe postoperative analgesia can be provided with PCEA in a general surgical ward without recourse to high-dependency supervision.

    Full Text Available Progressive epidural hematoma (PEDH after head injury is often observed on serial computerized tomography (CT scans. Recent advances in imaging modalities and treatment might affect its incidence and outcome. In this study, PEDH was observed in 9.2% of 412 head trauma patients in whom two CT scans were obtained within 24 hours of injury, and in a majority of cases, it developed within 3 days after injury. In multivariate logistic regression, patient gender, age, Glasgow Coma Scale (GCS score at admission, and skull fracture were not associated with PEDH, whereas hypotension (odds ratio (OR 0.38, 95% confidence interval (CI 0.17–0.84, time interval of the first CT scanning (OR 0.42, 95% CI 0.19–0.83, coagulopathy (OR 0.36, 95% CI 0.15–0.85, or decompressive craniectomy (DC (OR 0.46, 95% CI 0.21–0.97 was independently associated with an increased risk of PEDH. The 3-month postinjury outcome was similar in patients with PEDH and patients without PEDH (χ2=0.07, P=0.86. In conclusion, epidural hematoma has a greater tendency to progress early after injury, often in dramatic and rapid fashion. Recognition of this important treatable cause of secondary brain injury and the associated risk factors may help identify the group at risk and tailor management of patients with TBI.

    The effect of L-alanine administration on blood pressure (BP) during haemorrhagic shock was investigated using anesthetized rats whose left carotid arteries were cannulated for BP measurement, blood removal, and drug administration. It was found that L-alanine, in doses of 10, 25, 50, 100, and 200 mg/kg, increased the systolic BP of hypotensive rats by 38 to 80 percent (while 100 mg/kg pyruvate increased BP by only 9.4 mmhg, not significantly different from saline). The results suggest that L-alanine might influence cardiovascular function.

    To compare the efficacy and side-effects of 0.5% ropivacaine with that of 0.5% bupivacaine when used for single-shot epidural anaesthesia for orthopaedic surgery. Design: Randomized controlled trial. Place and Duration of Study: Department of Anesthesiology, Combined Military Hospital Rawalpindi, over a period of eight months from June 2013 to January 2014. Patients and Methods: The study was carried out in 60 ASA physical status I, II or III patients undergoing elective lower extremity orthopedic surgery. Two groups of 30 patients each received single-shot epidural anaesthesia either with ropivacaine 0.5% (ropivacaine group) or bupivacaine 0.5% (bupivacaine group). Onset, time for maximum height and median height of sensory block was assessed as well as time to two segment recession. Modified Bromage scale was used for motor blockade. Total duration of motor block and common side effects were also recorded. Results: The patients in both groups were similar in age, height, weight, gender and ASA status. There was no significant difference in onset of sensory block and time for maximum height of sensory block. The median heighest level of sensory block was T6 (T5-T8) for ropivacaine group and T5 (T4-T7) for bupivacaine group. Time for two segment regression and duration of sensory block were also comparable for both groups. The total duration of motor block was significantly more in bupivacaine group (159 min vs 134.2 min, p< 0.001). Modified Bromage scale was also significantly higher in bupivacaine group (2.86 vs 1.96 min, p<0.001). Side effects like hypotension, bradycardia, nausea, vomiting and shivering were similar in both groups. Conclusion: Epidural administration of 0.5% ropivacaine provided effective and good quality anaesthesia. Motor blockade was of less duration as compared to equivalent dose of 0.5% bupivacaine, which may offer potential benefit of early patient mobilization after orthopaedic surgery. (author)

    Full Text Available Effects of continuous low-dose epidural bupivacaine (0.05-0.1% infusion on the Doppler velocimetry for labor analgesia have been well documented. The aim of this study was to monitor the activity of the autonomic nervous system (ANS for women in labor based on Hilbert Huang transform (HHT, which performs signal processing for nonlinear systems, such as human cardiac systems. Thirteen pregnant women were included in the experimental group for labor analgesia. They received continuous epidural bupivacaine 0.075% infusion. The normal-to-normal intervals (NN-interval were downloaded from an ECG holter. Another 20 pregnant women in non-anesthesia labor (average gestation age was 38.6 weeks were included in the comparison group. In this study, HHT was used to decompose components of ECG signals, which reflect three different frequency bands of a person's heart rate spectrum (viz. high frequency (HF, low frequency (LF and very low frequency (VLF. It was found that the change of energy in subjects without anesthesia was more active than that with continuous epidural bupivacaine 0.075% infusion. The energy values of the experimental group (i.e., labor analgesia of HF and LF of ANS activities were significantly lower (P < 0.05 than the values of the comparison group (viz. labor without analgesia, but the trend of energy ratio of LF/HF was opposite. In conclusion, the sympathetic and parasympathetic components of ANS are all suppressed by continuous low-dose epidural bupivacaine 0.075% infusion, but parasympathetic power is suppressed more than sympathetic power.

    A double-blinded randomized controlled study to compare discharge time and patient satisfaction between two groups of patients submitted to open surgeries for abdominal malignancies using segmental thoracic spinal or general anesthesia. Open surgeries for abdominal malignancy are usually done under general anesthesia, but many patients with major medical problems sometimes can't tolerate such anesthesia. Regional anesthesia namely segmental thoracic spinal anesthesia may be beneficial in such patients. A total of 60 patients classified according to American Society of Anesthesiology (ASA) as class II or III undergoing surgeries for abdominal malignancy, like colonic or gastric carcinoma, divided into two groups, 30 patients each. Group G, received general anesthesia, Group S received a segmental (T9-T10 injection) thoracic spinal anesthesia with intrathecal injection of 2 ml of hyperbaric bupivacaine 0.5% (10 mg) and 20 ug fentanyl citrate. Intraoperative monitoring, postoperative pain, complications, recovery time, and patient satisfaction at follow-up were compared between the two groups. Spinal anesthesia was performed easily in all 30 patients, although two patients complained of paraesthesiae, which responded to slight needle withdrawal. No patient required conversion to general anesthesia, six patients required midazolam for anxiety and six patients required phenylephrine and atropine for hypotension and bradycardia, recovery was uneventful and without sequelae. The two groups were comparable with respect to gender, age, weight, height, body mass index, ASA classification, preoperative oxygen saturation and preoperative respiratory rate and operative time. This preliminary study has shown that segmental thoracic spinal anesthesia can be used successfully and effectively for open surgeries for abdominal malignancies by experienced anesthetists. It showed shorter postanesthesia care unit stay, better postoperative pain relief and patient satisfaction than

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

  1. Delayed epidural hematoma after mild head injury

    2005-01-01

    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.

    Intracranial hypotension (IH) is a rare condition caused by leakage of cerebrospinal fluid (CSF). Recently, a small number of clinicians have proposed a new concept about IH following minor head injury. They suggest that many of their patients with IH can be successfully treated with epidural blood patch therapy. They also argue that some patients with post-traumatic cervical syndrome and general fatigue syndrome suffer from IH following minor head injury. Consequently, IH following minor head injury was widely recognized and dealt with as a social problem in Japan. On the other hand, pathophysiological aspects of the condition as well as the provisional criteria to describe this clinical entity remain to be elucidated. In 2006, the Japan Society of Neurotraumatology performed a questionnaire survey asking 44 hospitals belonging to trustees of this society about IH following minor head injury. This paper provides a report of the outcomes of this survey. The response rate to this questionnaire was 57% (25/44). Fifty-six percent of respondents did not have experience of IH following minor head injury. Moreover, respondents' criteria for describing this disease differed greatly, especially in the radiological examinations and symptoms for the diagnosis of this entity which showed significant variation. These problems might originate from the general features of this disease. With the exception of postural headache, the symptoms of this disease varied enormously. This wide range of symptoms confused with the pathophysiolosies of a great many similar conditions. As such, clarifications of the pathophysiological characteristics of IH following minor head injury, together with consensus on specific criteria to describe the condition, are required. In conclusion, the results of this survey revealed many serious scientific and social problems associated with the diagnosis and treatment of intracranial hypotension following minor head injury. Scientific study including the

    Prompt treatment of severe blood pressure instability requires both cognitive and technical skill. The ability to anticipate and respond to episodes of hemodynamic instability should improve with training. The authors tested the hypothesis that the duration of severe hypotension during anesthesia administered by residents correlates with concurrent adjusted overall performance evaluations by the Clinical Competence Committee and subsequent in-training exam scores. The authors obtained data on 70 first- and second-year anesthesia residents at the Cleveland Clinic. Analysis was restricted to adults having noncardiac surgery with general anesthesia. Outcome variables were in-training exam scores and subjective evaluations of resident performance ranked in quintiles. The primary predictor was cumulative systolic arterial pressure less than 70 mmHg. Secondary predictors were administration of vasopressors, frequency of hypotension, average duration of hypotensive episodes, and blood pressure variability. The primary statistical approach was mixed-effects modeling, adjusted for potential confounders. The authors considered 15,216 anesthesia care episodes. A total of 1,807 hypotensive episodes were observed, lasting an average of 32 ± 20 min (SD) per 100 h of anesthesia, with 68% being followed by vasopressor administration. The duration of severe hypotension (systolic pressure less than 70 mmHg) was associated with neither Competence Committee evaluations nor in-training exam scores. There was also no association between secondary blood pressure predictors and either Competence Committee evaluations or in-training exam results. There was no association between any of the five blood pressure management characteristics and either in-training exam scores or clinical competence evaluations. However, it remains possible that the measures of physiologic control, as assessed from electronic anesthesia records, evaluate useful but different aspects of anesthesiologist

    2013-04-11

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

  18. Rapidly Progressive Spontaneous Spinal Epidural Abscess

    2016-01-01

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

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

    Presence of comorbidity in surgical patients may be associated with adverse perioperative events and increased the risk of morbidity and mortality. This audit was conducted to determine the frequencies of comorbidities in elective surgical patients and the outcome of anesthesia in a Tertiary Hospital in Nigeria. Observational study of a cross-section of adult patients scheduled for elective surgery over a 6-month period. A standardized questionnaire was used to document patients' demographics, the presence of comorbidity and type, surgical diagnosis, anesthetic technique, intraoperative adverse events, and outcome of anesthesia. The questionnaire was administered pre- and post-operatively to determine the effects of the comorbidities on the outcome of anesthesia. One hundred and sixty-five adult patients aged between 18 and 84 years were studied. There were 89 (53.9%) females and 76 (46.1%) males. Forty-five (27.3%) have at least one comorbidity. Hypertension was the most common (48.8%) associated illness. Other comorbidities identified include anemia (17.8%), asthma (8.9%), diabetes mellitus (6.7%), chronic renal disease (6.7%), and others. The perioperative period was uneventful in majority of patients (80.6%) despite the presence of comorbidities. Intraoperative adverse events include hypotension, hypertension, shivering, and vomiting. No mortality was reported. Hypertension was the most common comorbidity in this cohort of patients. The presence of comorbidity did not significantly affect the outcome of anesthesia in elective surgical patients.

    Semi-quantitative radionuclide cisternography was performed to evaluate cerebrospinal fluid (CSF) leakage for patients with long-lasting headache and/or neck pain or refractory dizziness which appeared to be related to posture as well as patients with spontaneous intracranial hypotension (SIH). Radioactivity in the whole CSF space was counted and was plotted against time. SIH cases showed rapid decrease of radioactivity in the CSF space. Chronic headache patients were divided into Group I (rapid decrease of activity similarly to those in patients with SIH, to less than 80% at 5 h and 40% at 24 h), Group II (gradual decrease to less than 40% at 24 h), and Group III (activity remained more than 80% at 5 h and 40% at 24 h). Of 16 patients in Group I, epidural blood patch was attempted in 14, and improvement of symptoms was obtained in 10. In 3 patients who underwent post-treatment RI study, tracer kinetics was normalized. These findings may indicate that some of patients with chronic headache actually have CSF leakage that can be treated with epidural blood patch. (author)

    2013-01-01

    Full Text Available Background/Aim. In spite of the evidence suggesting a significant morbidity associated with blood transfusions, the use of blood and blood products remain high in cardiac surgery. To successfully minimize the need for blood transfusion, a systematic approach is needed. The aim of this study was to investigate the influence of different anesthetic techniques, general vs combine epidural and general anesthesia, as well as different surgery strategies, on-pump vs off-pump, on postoperative bleeding complications and the need for blood transfusions during perioperative period. Methods. Eighty-two consecutive patients scheduled for coronary artery bypass surgery were randomized according to surgical and anesthetic techniques into 4 different groups: group 1 (patients operated on off-pump, under general anesthesia; group 2 (patients operated on off-pump, with combined general and high thoracic epidural anesthesia; group 3 (patients operated on using standard revascularization technique, with the use of extracorporeal circulation, under general anesthesia, and group 4 (patients operated on using standard revascularization technique, with the use of extracorporeal circulation, with combined general and high thoracic epidural anesthesia. Indications for transfusion were based on clinical judgment, but a restrictive policy was encouraged. Bleeding was considered significant if it required transfusion of blood or blood products, or reopening of the chest. The quantity of transfused blood or blood products was specifically noted. Results. None of the patients was transfused blood or blood products during the surgery, and as many as 70/81 (86.4% patients were not transfused at all during hospital stay. No difference in postoperative bleeding or blood transfusion was noted in relation to the type of surgery and anesthetic technique applied. If red blood cells were transfused, postoperative bleeding was the most influential parameter for making clinical

  3. Depth of Anesthesia as a Risk Factor for Perioperative Morbidity

    2015-01-01

    Full Text Available Introduction. The prognostic value of age, physical status, and duration of surgery on perioperative course has been extensively studied. However, the impact of deep hypnotic time (time when Bispectral Index values are less than 40 has not been well evaluated. Methods. We designed an observational study to clarify the relative influence of deep hypnotic time (DHT on outcome. Eligible participants were mentally stable patients over 18 years old scheduled for elective major abdominal surgery. In total, 248 patients enrolled. Data were analyzed using Fisher’s exact test and multiple logistic regression. Results. Five variables (DHT, hypotension, age, comorbidity, and duration of surgery showed statistically significant association with complications, when examined independently. However, when all variables were examined together in a multiple logistic regression model, age and comorbidity were no longer associated with outcome. DHT, hypotension, and duration of surgery were significant predictors of “complications,” and “hypotension” was a significant predictor of prolonged hospital stay (P<0.001.  Conclusion. Deep hypnotic time emerged as a new factor associated with outcome, and its impact compared to other factors such as age, surgery duration, hypotension, and comorbidity is redefined. Monitoring and managing depth of anesthesia during surgery are important and should be part of careful operation planning.

    To explore and improve the quality of continuous epidural analgesia for pain relief using Statistical Process Control tools. Measuring the quality of pain management interventions is complex. Intermittent audits do not accurately capture the results of quality improvement initiatives. The failure rate for one intervention, epidural analgesia, is approximately 30% in everyday practice, so it is an important area for improvement. Continuous measurement and analysis are required to understand the multiple factors involved in providing effective pain relief. Process control and quality improvement Routine prospectively acquired data collection started in 2006. Patients were asked about their pain and side effects of treatment. Statistical Process Control methods were applied for continuous data analysis. A multidisciplinary group worked together to identify reasons for variation in the data and instigated ideas for improvement. The key measure for improvement was a reduction in the percentage of patients with an epidural in severe pain. The baseline control charts illustrated the recorded variation in the rate of several processes and outcomes for 293 surgical patients. The mean visual analogue pain score (VNRS) was four. There was no special cause variation when data were stratified by surgeons, clinical area or patients who had experienced pain before surgery. Fifty-seven per cent of patients were hypotensive on the first day after surgery. We were able to demonstrate a significant improvement in the failure rate of epidurals as the project continued with quality improvement interventions. Statistical Process Control is a useful tool for measuring and improving the quality of pain management. The applications of Statistical Process Control methods offer the potential to learn more about the process of change and outcomes in an Acute Pain Service both locally and nationally. We have been able to develop measures for improvement and benchmarking in routine care that

    Articaine is an intermediate-potency, short-acting amide local anesthetic with a fast metabolism due to an ester group in its structure. It is effective with local infiltration or peripheral nerve block in dentistry, when administered as a spinal, epidural, ocular, or regional nerve block, or when injected intravenously for regional anesthesia. In comparative trials, its clinical effects were not generally significantly different from those of other short-acting local anesthetics like lidocaine, prilocaine, and chloroprocaine, and there is no conclusive evidence demonstrating above-average neurotoxicity. Articaine proved to be suitable and safe for procedures requiring a short duration of action in which a fast onset of anesthesia is desired, eg, dental procedures and ambulatory spinal anesthesia, in normal and in special populations.

    Thoracic spinal anesthesia has been used for laparoscopic cholecystectomy and abdominal surgeries, but not in breast surgery. The present study compared this technique with general anesthesia in breast cancer surgeries. Forty patients were enrolled in this comparative study with inclusion criteria of ASA physical status I-III, primary breast cancer without known extension beyond the breast and axillary nodes, scheduled for unilateral mastectomy with axillary dissection. They were randomly divided into two groups. The thoracic spinal group (S) (n = 20) underwent segmental thoracic spinal anesthesia with bupivacaine and fentanyl at T5-T6 interspace, while the other group (n = 20) underwent general anesthesia (G). Intraoperative hemodynamic parameters, intraoperative complications, postoperative discharge time from post-anesthesia care unit (PACU), postoperative pain and analgesic consumption, postoperative adverse effects, and patient satisfaction with the anesthetic techniques were recorded. Intraoperative hypertension (20%) was more frequent in group (G), while hypotension and bradycardia (15%) were more frequent in the segmental thoracic spinal (S) group. Postoperative nausea (30%) and vomiting (40%) during PACU stay were more frequent in the (G) group. Postoperative discharge time from PACU was shorter in the (S) group (124 ± 38 min) than in the (G) group (212 ± 46 min). The quality of postoperative analgesia and analgesic consumption was better in the (S) group. Patient satisfaction was similar in both groups. Segmental thoracic spinal anesthesia has some advantages when compared with general anesthesia and can be considered as a sole anesthetic in breast cancer surgery with axillary lymph node clearance.

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

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

    The traditional classification methods of dental local anesthesia must be modified. In this paper we proved that the vascular mechanism is leading component of spongy injection. It is necessary to take into account the high effectiveness and relative safety of spongy anesthesia, as well as versatility, ease of implementation and the growing prevalence in the world. The essence of the proposed modification is to distinguish the methods in diffusive (including surface anesthesia, infiltration and conductive anesthesia) and vascular-diffusive (including intraosseous, intraligamentary, intraseptal and intrapulpal anesthesia). For the last four methods the common term «spongy (intraosseous) anesthesia» may be used.

    Epidural anesthesia is one of the most commonly used and yet challenging techniques employed for pain management and anesthesia delivery. The major complications of this procedure are due to accidental dural puncture, with an incidence of 1-3%, which could lead to both temporary and irreversible permanent neurological complications. Needle placement under ultrasound (US) guidance has received increasing interest for improving needle placement accuracy. However, poor needle visibility in US, difficulties in displaying relevant anatomical structure such as dura mater due to attenuation and bone shadowing, and image interpretation variability among users pose significant hurdles for any US guidance system. As a result, US guidance for epidural injections has not been widely adopted for everyday use for the performance of neuraxial blocks. The difficulties in localizing the ligamentum flavum and dura with respect to the needle tip can be addressed by integrating A-mode US, provided by a single-element transducer at the needle tip, into the B-mode US guidance system. We have taken the first steps towards providing such a guidance system. Our goal is to improve the safety of this procedure with minimal changes to the clinical workflow. This work presents the design and development of a 20 MHz single-element US transducer housed at the tip of a 19 G needle hypodermic tube, which can fit inside an epidural introducer needle. In addition, the results from initial transducer characterization tests and performance evaluation of the transducer in a euthanized porcine model are provided.

  3. Ambulatory surgery with chloroprocaine spinal anesthesia: a review

    Full Text Available Daniela Ghisi, Stefano Bonarelli Department of Anaesthesia and Postoperative Intensive Care, Istituto Ortopedico Rizzoli, Bologna, Italy Abstract: Spinal anesthesia is a reliable and safe technique for procedures of the lower extremities. Nevertheless, some of its characteristics may limit its use for ambulatory surgery, including delayed ambulation, risk of urinary retention, and pain after block regression. The current availability of short-acting local anesthetics has renewed interest for this technique also in the context of short- and ultra-short procedures. Chloroprocaine (CP is an amino-ester local anesthetic with a very short half-life. It was introduced and has been successfully used for spinal anesthesia since 1952. Sodium bisulfite was then added as a preservative after 1956. The drug was then abandoned in the 1980s for several reports of neurological deficits in patients receiving accidentally high doses of intrathecal CP during epidural labor analgesia. Animal studies have proven the safety of the preservative-free formulation, which has been extensively evaluated in volunteer studies as well as in clinical practice with a favorable profile in terms of both safety and efficacy. In comparison with bupivacaine, 2-chloroprocaine (2-CP showed faster offset times to end of anesthesia, unassisted ambulation, and discharge from hospital. These findings suggests that 2-CP may be a suitable alternative to low doses of long-acting local anesthetics in ambulatory surgery. Its safety profile also suggests that 2-CP could be a valid substitute for intrathecal short- and intermediate-acting local anesthetics, such as lidocaine and mepivacaine – often causes of transient neurological symptoms. In this context, literature suggests a dose ranging between 30 and 60 mg of 2-CP for procedures lasting 60 minutes or less, while 10 mg is considered the no-effect dose. The present review describes recent evidence about 2-CP as an anesthetic agent for

    Full Text Available Spontaneous intracranial hypotension (SIH is a syndrome in which hypovolemia of the cerebrospinal fluid (CSF results in various symptoms. Although its prognosis is usually benign, cases with a rapid neurologic deterioration resulting in an altered mental status have been reported. One of the characteristic radiographic findings in such cases is the presence of bilateral accumulation of subdural fluid (hematoma/hygroma. When SIH-related subdural hematoma is present only unilaterally with a concomitant midline shift, making an accurate diagnosis may be challenging, and inadvertent hematoma evacuation may result in further neurologic deterioration. We report a 58-year-old woman with an altered mental status who had visited a local hospital and in whom a brain CT showed a unilateral subdural hematoma with a marked midline shift. She was referred to our department because of her neurologic deterioration after hematoma evacuation. A CT myelography revealed a massive CSF leakage in the entire thoracic epidural space. She made a full neurologic recovery following blood patch therapy. Our case is unique and educational because the suspicion for SIH as an underlying cause of subdural hematoma is warranted in nongeriatric patients not only with bilateral but also unilateral lesions. An immediate search for CSF leakage may be important in cases with failed hematoma evacuation surgery.

  5. Anesthesia for radiologic procedures

    Anesthetic techniques for neurodiagnostic studies and radiation therapy have been recently reviewed, but anesthetic involvement in thoracic and abdominal radiology has received little attention. Patient reactions to radiologic contrast media may be of concern to the anesthesiologist, who is often responsible for injecting these agents during diagnostic procedures, and thus is included in this discussion. Finally, the difficulties of administering anesthesia for magnetic resonance imaging (MRI) scans are outlined, in an effort to help anesthesiologist to anticipate problems with this new technologic development. Although there are very few indications for the use of general anesthesia for diagnostic radiologic studies in adults, most procedures performed with children, the mentally retarded, or the combative adult require either heavy sedation or general anesthesia. In selecting an anesthetic technique for a specific procedure, both the patient's disease process and the requirements of the radiologist must be carefully balanced

    Dobutamine as a predominant beta-1 agonist increases heart rate and myocardial contractility and at sufficient high doses, it also increases systolic blood pressure. This study was undertaken to describe instances of paradoxical hypotension during dobutamine infusion for Tl-201 myocardial perfusion SPECT study and the relationship between scintigraphic findings and hypotension occurred during dobutamine infusion. Methods: In 201 consecutive patients unable to perform adequate exercise, dobutamine Tl-201 myocardial SPECT was performed. Dobutamine was infused starting from 10 μg/kg/min increasing to 40 μ/kg/min. Paradoxical hypotension was defined as a decrease in systolic blood pressure ≥ 20 mmHg compared with baseline study. Paradoxical hypotension was observed in 40 patients (Group A) out of 201 (19.9%) while no significant change in systolic blood pressure was detected in the remaining 161 patients (Group B). Mean maximum fall in systolic blood pressure was 39±18 mmHg (range: 20-90). In 33 of 40 patients (83%) with paradoxical hypotension, scintigraphy was normal compared to 131 (81%) of the remaining 161 patients. In patients of Group A, angiography, echocardiography and tilt table tests were performed in 13, 11 and 6 patients respectively. Nine of 13 angiographic evaluations (69%), 10 of 11 echocardiographic evaluations (91%), all of the tilt table tests were normal. Additionally, all of the patients of Group A were clinically followed up at least 6 months after the myocardial perfusion scintigraphy. None of the patients had a cardiac event except one patient during the follow-up period. Conclusion: Paradoxical hypotension during dobutamine infusion for myocardial scintigraphy is not an uncommon finding and up to 19.9% patients may develop such hypotension. To maximize test safety, precautions should be taken during dobutamine myocardial stress test, since remarkable decrease in systolic blood pressure may occur. Unlike hypotension occurring with exercise

    Pediatric patients often undergo anesthesia for ambulatory procedures. This article discusses several common preoperative dilemmas, including whether to postpone anesthesia when a child has an upper respiratory infection, whether to test young women for pregnancy, which children require overnight admission for apnea monitoring, and the effectiveness of nonpharmacological techniques for reducing anxiety. Medication issues covered include the risks of anesthetic agents in children with undiagnosed weakness, the use of remifentanil for tracheal intubation, and perioperative dosing of rectal acetaminophen. The relative merits of caudal and dorsal penile nerve block for pain after circumcision are also discussed. Copyright © 2014 Elsevier Inc. All rights reserved.

    Risk in pediatric anesthesia can be conveniently classified as minor or major. Major morbidity includes cardiac arrest, brain damage and death. Minor morbidity can be assessed by clinical audits with small patient samples. Major morbidity is rare. It is best assessed by very large clinical studies and by review of closed malpractice claims. Both minor and major morbidity occur most commonly in infants and children under three, especially those with severe co-morbidities. Knowledge of risk profiles in pediatric anesthesia is a starting point for the reduction of risk. © 2010 Blackwell Publishing Ltd.

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

CONCLUSIONES: La mezcla enantiomérica de bupivacaína (S75-R25 presentó mayor tiempo analgésico y menor grado de bloqueo motor, comparada con la solución de bupivacaína racémicaBACKGROUND AND OBJECTIVES: A bupivacaine formulation containing 25% of R(+ and 75% of S(- isomer has been used because its anesthetic properties with less toxicity than the racemic bupivacaine. This study aimed at evaluating the racemic bupivacaine as compared to B25/75 in epidural anesthesia. METHODS: Participated in this study 44 patients who were distributed in two groups (n = 22, namely Bupivacaine and S75-R25. Patients were premedicated with intravenous midazolam. Epidural anesthesia was induced at L3-L4 or L2-L3 interspace with 16 to 24 ml of the anesthetic solution. Group Bupivacaine received 0.5% bupivacaine with vasoconstrictor. Group S75-R25 received the enantiomeric mixture of 0.5% bupivacaine with vasoconstrictor. The following parameters were evaluated: lower limb temperature before and after epidural block, blockade onset, type of sensation referred by the patient, possible sensory failures, metameric sensory level and motor block level. Time for first analgesic request in the PACU was also recorded. RESULTS: Forty-one patients completed the study. Groups were demographically similar. Perioperative midazolam dose, epidural anesthetic volume, blockade onset, sensory failures at pinprick, lower limb temperature in different moments, type of paresthesia sensation and anesthetic depth in dermatomes were similar between groups. Motor block was less intense in group S75-R25 (p = 0.0117 as compared to group Bupivacaine. Time to first postoperative analgesic dose was longer for group S75-R25 as compared to group Bupivacaine (596 ± 436

There are several methods to provide anesthesia during awake craniotomy including local anesthesia infiltration, local anesthesia plus conscious sedation, general anesthesia and wake-up during surgery and sleep again (asleep-awake-asleep or AAA. Each method has its pro and con with different complications. In Siriraj Hospital, there was no prior study of anesthetic techniques and complications of awake craniotomy. Methods: The retrospective descriptive study of awake craniotomy was carried out with 60 patients in Siriraj Hospital 2007-2011. Results: There were 35 males (58.3% with average age 40.7±12.6 years and weight 64.2±12 kilograms undergoing awake craniotomy. Twenty patients (33.3% presented with seizure before surgery.

    Orthostatic tolerance may be defined as the ability of humans to maintain cerebral perfusion and consciousness upon movement from a supine or sitting position to the upright posture; for example, subjects can stand suddenly or be tilted to the head-up body position. Similar but not identical physiological responses can be induced by positive G(sub Z) (head to foot) acceleration or exposure to lower body negative pressure (LBNP). The objective is to suddenly shift blood to the lower body to determine how effectively cardiovascular and neural-hormonal compensatory responses react to maintain blood pressure. In the most precise method for measuring tolerance, individuals would be stressed until they faint (syncope). However, the potential consequences and discomforts of such a test usually prohibit such a procedure so that few investigators actually induce syncope. In a more common approach, subjects are exposed to a given level of stress, for example, head-up tilt for 15 min, and any increases in heart rate or decreases in blood pressure are interpreted as indicators of progress toward syncope. Presumably, the greater the perturbation of heart rate and blood pressure, the closer to "tolerance," i.e., point of unconsciousness. Another more appropriate approach is to induce a progressively increasing hypotensive stress until pre-determined physiological responses or pre-syncopal symptoms appear. The physiological criteria may include a sudden drop in systolic blood pressure (greater than 25 mm/min), a sudden drop in heart rate (greater than 15 beats/min), or a systolic blood pressure less than 70 mmHg. The most common pre-syncopal symptoms include lightheadedness, stomach awareness or distress, feelings of warmth, tingly skin, and light to profuse sweating. Usually a combination of physiological responses and symptoms occurs such that, on different days, the tolerance time to the same orthostatic protocol is reproducible for a given individual. The assumption is that

    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.)

    Full Text Available There are many advantages in using epidural anesthesia technique. However, there are also some constraints, such as the relatively long onset, particularly in the case of bupivacaine. Whereas the need of a rapid onset of anesthesia technique for emergency cares is increasing lately. The objective of this study was to find a method to hasten the onset of bupivacaine. This is a cross sectional randomized double blind controlled clinical trial performed on 40 patients who would undergo lower abdomen and extremity surgery with epidural block. We evaluated the onset of action of bupivacaine which has been added with sodium bicarbonate. Consecutive sampling method was applied to get the sample. The criteria of sample are ASA I – II patient, aged of 20-60 years old, 50-60 kg of weight, 150-170 cm of height. Patients were allocated randomly into two groups. The treatment group would get epidural block using mixture of 20 cc of bupivacaine 0,5 % + 0.5 cc of sodium bicarbonate 1.4 %, whereas the control group received 20 cc bupivacaine 0.5 % + 0.5 cc aqua bides. Time to reach sensoric block at the level of thoracal 10 dermatome using the pinprick method and time to reach motoric blockade using the bromage scale was recorded. The result of this study showed a significant shortening of the onset of sensory blockade (p<0.05 in the treatment group (10.2±1.4 minutes compared with the control group (19.5±1.3 minutes. The onset of motor blockade had also a significant shortening (p<0.05 in the treatment group(13.3±1.6 minutes compared with the control group (23.0±1.2 minutes. It was concluded that the addition of sodium bicarbonate can hasten the onset of bupivacaine on epidural block.

  20. Defining depth of anesthesia.

    Science.gov (United States)

    Shafer, S L; Stanski, D R

    2008-01-01

    In this chapter, drawn largely from the synthesis of material that we first presented in the sixth edition of Miller's Anesthesia, Chap 31 (Stanski and Shafer 2005; used by permission of the publisher), we have defined anesthetic depth as the probability of non-response to stimulation, calibrated against the strength of the stimulus, the difficulty of suppressing the response, and the drug-induced probability of non-responsiveness at defined effect site concentrations. This definition requires measurement of multiple different stimuli and responses at well-defined drug concentrations. There is no one stimulus and response measurement that will capture depth of anesthesia in a clinically or scientifically meaningful manner. The "clinical art" of anesthesia requires calibration of these observations of stimuli and responses (verbal responses, movement, tachycardia) against the dose and concentration of anesthetic drugs used to reduce the probability of response, constantly adjusting the administered dose to achieve the desired anesthetic depth. In our definition of "depth of anesthesia" we define the need for two components to create the anesthetic state: hypnosis created with drugs such as propofol or the inhalational anesthetics and analgesia created with the opioids or nitrous oxide. We demonstrate the scientific evidence that profound degrees of hypnosis in the absence of analgesia will not prevent the hemodynamic responses to profoundly noxious stimuli. Also, profound degrees of analgesia do not guarantee unconsciousness. However, the combination of hypnosis and analgesia suppresses hemodynamic response to noxious stimuli and guarantees unconsciousness.

    2014-06-01

    Full Text Available Introduction: A restricted sympathetic block during spinal anesthesia may minimize hemodynamic changes. This prospective randomized study compared unilateral and bilateral spinal anesthesia with respect to the intra- and postoperative advantages and complications of each technique. Material and methods: Spinal anesthesia was induced with 0.5% hyperbaric bupivacaine and a 25-G Quincke needle (Dr. J in two groups of patients with physical status ASA I-II who had been admitted for orthopedic surgeries. In group A, dural puncture was performed with the patient in a seated position using 2.5 cm3 of hyperbaric bupivacaine. Each patient was then placed in the supine position. In group B, dural puncture was performed with the patient in the lateral decubitus position with 1.5 cm3 of hyperbaric bupivacaine. The lower limb was the target limb. The speed of injection was 1 mL/30 s, and the duration of time spent in the lateral decubitus position was 20 min. Results: The demographic data were similar in both groups. The time to the onset of the sensory and motor block was significantly shorter in group A (p = 0.00. The duration of motor and sensory block was shorter in group B (p < 0.05. The success rate for unilateral spinal anesthesia in group B was 94.45%. In two patients, the spinal block spread to the non-dependent side. The incidence of complications (nausea, headache, and hypotension was lower in group B (p = 0.02. Conclusion: When unilateral spinal anesthesia was performed using a low-dose, low-volume and low-flow injection technique, it provides adequate sensory-motor block and helps to achieve stable hemodynamic parameters during orthopedic surgery on a lower limb. Patients were more satisfied with this technique as opposed to the conventional approach. Furthermore, this technique avoids unnecessary paralysis on the non-operated side.

    Materials and Methods: In a private rural medical college, 150 patients were selected prospectively for laparoscopic cholecystectomy, under low-pressure (8mmHg pneumoperitoneum and under spinal anesthesia over a span of one and a half years. Injection bupivacaine (0.5% was used for spinal anesthesia. All ports were made in a head-down position to avoid hypotension. Shoulder pain was managed by reassurance as well as by diverting the attention and sedation in a few cases. Results: We successfully performed the operations in 145 patients without major complications. Spinal anesthesia was converted to general anesthesia in five patients due to severe shoulder pain. Age varied between 21 and 75 years. Duration of operation time (skin to skin was between 40 and 80 minutes. Twenty-nine patients complained of right shoulder pain. Most of them were managed by reassurance from the anesthetist and a few needed an injection of fentanyl along with midazolam. Conclusion: Laparoscopic cholecystectomy with low-pressure CO2 pneumoperitoneum is feasible and safe under spinal anesthesia. Incidence of postoperative shoulder pain and complications are comparable with laparoscopic cholecystectomy under general anesthesia. [Arch Clin Exp Surg 2012; 1(4.000: 224-228

    Hypotension occurs in 20% of hemodialysis procedures. To study the effects of midodrine on hypotension during hemodialysis. Ten patients on chronic hemodialysis and with a history of hypotension during the procedure, were studied. They received midodrine 10 mg per os or placebo during 5 dialytic procedures each, in a double blind cross over design. Blood pressure levels prior to dialysis were similar during the midodrine or placebo administration periods. During dialysis, systolic blood pressure fell 19.3 +/- 28 mmHg with midodrine and 23.4 +/- 28 mmHg with placebo. Diastolic blood pressure fell 7.3 +/- 11.5 mmHg with midodrine and 11.1 +/- 12 mmHg with placebo. The reduction in median arterial pressure was also less pronounced with midodrine. Midodrine lessens the fall in arterial pressure during hemodialysis, in patients with symptomatic hypotension.

    Full Text Available Hemodynamic instability during hemodialysis is a common but often underestimated issue in the nephrologist practice. Intradialytic hypotension, namely, a decrease of systolic or mean blood pressure to a certain level, prohibits the safe and smooth achievement of ultrafiltration and solute removal goal in chronic dialysis patients. Studies have elucidated the potential mechanisms involved in the development of Intradialytic hypotension, including excessive ultrafiltration and loss of compensatory mechanisms for blood pressure maintenance. Cardiac remodeling could also be one important piece of the puzzle. In this review, we intend to discuss the role of cardiac remodeling, including left ventricular hypertrophy, in the development of Intradialytic hypotension. In addition, we will also provide evidence that a bidirectional relationship might exist between Intradialytic hypotension and left ventricular hypertrophy in chronic dialysis patients. A more complete understanding of the complex interactions in between could assist the readers in formulating potential solutions for the reduction of both phenomena.

    EA at P 5–6 and S 36–37 using low current and low frequency may be able to reduce elevated blood pressure in a subset of patients (~70%) with mild to moderate hypertension. The effect is slow in onset but is long-lasting. Experimental studies have shown that EA inhibition of cardiovascular sympathetic neurons that have been activated through visceral reflex stimulation is through activation of neurons in the arcuate nucleus of the hypothalamus, vlPAG in the midbrain and NRP in the medulla, which, in turn, inhibit the activity of premotor sympathetic neurons in the rVLM. The arcuate also provides direct projections to the rVLM that contain endorphins. Glutamate, acetylcholine, opioids, GABA, nociceptin, serotonin and endocannabinoids all appear to participate in the EA hypotensive response although their importance varies between nuclei. Thus, a number of mechanisms underlying the long-lasting effect of EA on cardiovascular function have been identified but clearly further investigation is warranted. PMID:20444652

    Generalized cerebral ischaemia from cardiovascular dysfunction usually leads to presyncopal dizziness, but several studies reported a higher frequency of rotatory vertigo in cardiovascular patients. Whether generalized cerebral ischaemia due to cardiovascular disorders may produce objective vestibular dysfunction was investigated. Thirty-three patients with orthostatic dizziness/vertigo due to profound orthostatic hypotension and 30 controls were recruited. All participants underwent recording of eye movements during two orthostatic challenging tests: the Schellong and the squatting-standing tests. Most patients had neuroimaging, and patients with abnormal eye movements were subjected to follow-up evaluations. Symptoms associated with orthostatic dizziness/vertigo included blurred vision, fainting and tinnitus. Ten (30%) of 33 patients developed rotatory vertigo and nystagmus during the Schellong (n = 5) or squatting-standing test (n = 5). Four of them showed pure downbeat nystagmus whilst five had downbeat and horizontal nystagmus with or without torsional component. Patients with orthostatic nystagmus had shorter duration of orthostatic intolerance than those without nystagmus (1.0 ± 1.6 vs. 11.0 ± 9.7 months, P vertigo due to objective vestibular dysfunction. The presence of orthostatic vertigo and nystagmus has an association with the duration of orthostatic intolerance. © 2014 EAN.

    Laser resurfacing technology offers the ability to treat skin changes that are the result of the aging process. One of the major drawbacks of laser resurfacing technologies is the pain associated with the procedure. The methods of anesthesia used in laser resurfacing to help minimize the pain include both noninvasive and invasive procedures. The noninvasive procedures can be divided into topical, cryoanesthesia, and a combination of both. The invasive methods of anesthesia include injected forms (infiltrative, nerve blocks, and tumescent anesthesia) and supervised anesthesia (monitored anesthesia care and general anesthesia). In this review, the authors summarize the types of anesthesia used in laser resurfacing to aid the provider in offering the most appropriate method for the patient to have as painless a procedure as possible.

  13. Venlafaxine-Induced Orthostatic Hypotension in a Geriatric Patient

    Directory of Open Access Journals (Sweden)

    Vidyashree Chikkaramanjegowda

    2013-01-01

    Full Text Available Venlafaxine is not usually associated with risk of orthostatic hypotension. A 65-year-old US Caucasian female taking 225 mg/day of venlafaxine extended-release developed symptomatic orthostatic hypotension. The systolic and diastolic blood pressure dropped by 25 and 18 mm Hg, respectively, from supine position to standing position within 3 minutes. The patient was otherwise healthy and the orthostatic hypotension resolved with venlafaxine discontinuation. This was a probable venlafaxine adverse drug reaction according to the Naranjo scale. This case contributes to the scarce literature that indicates that clinicians need to be aware that occasionally venlafaxine can induce clinically significant orthostatic hypotension, particularly in geriatric patients. Our patient did not have orthostatic hypotension when she was taking venlafaxine at 60 years of age in higher venlafaxine doses (300 mg/day but developed this adverse drug reaction when venlafaxine was restarted at the geriatric age. This case indicates that a history of prior tolerance to venlafaxine does not guarantee tolerance after 65 years of age. If a clinician decides to use venlafaxine in geriatric patients, the clinician should warn the patient about the risk of orthostatic hypotension and consider very slow titration and low doses.

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

    The aim of this study was to compare the unilaterality of subarachnoid block achieved with hyperbaric and hypobaric ropivacaine. The prospective, randomized trial was conducted in an orthopedics surgical suite. In all, 60 ASA I-III patients scheduled for elective total knee arthroplasty were included in the study. Group Hypo (n=30) received 11.25mg of ropivacaine (7.5mg.mL(-1)) + 2mL of distilled water (density at room temperature was 0.997) and group Hyper (n=30) received 11.25mg of ropivacaine (7.5mg.mL(-1)) + 2mL (5mg.mL(-1)) of dextrose (density at room temperature was 1,015). Patients in the hyperbaric group were positioned with the operated side down and in the 15° Fowler position, versus those in the hypobaric group with the operated side facing up and in the 15° Trendelenburg position. Combined spinal epidural anesthesia was performed midline at the L(3-4) lumbar interspace. Hemodynamic and spinal block parameters, regression time, success of unilateral spinal anesthesia, patient comfort, surgical comfort, surgeon comfort, first analgesic requirement time, and adverse effects were assessed. Time to reach the T10 dermatome level on the operated side was shorter in group Hyper (612.00±163.29s) than in group Hypo (763.63±208.35s) (phyperbaric and hypobaric ropivacaine (11.25mg) provided adequate and dependable anesthesia for total knee replacement surgery, with a high level of patient and surgeon comfort. Hypobaric local anesthetic solutions provide a high level of unilateral anesthesia, with rapid recovery of both sensory and motor block, and therefore may be preferable in outpatient settings.

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

    Full Text Available Information overload of the anesthesiologist through technological advances have threatened the safety of patients under anesthesia in the operating room (OR. Traditional monitoring and alarm systems provide independent, spatially distributed indices of patient physiological state. This creates the potential to distract caregivers from direct patient care tasks. To address this situation, a novel reactive agent decision support system with graphical human machine interface was developed. The system integrates the disparate data sources available in the operating room, passes the data though a decision matrix comprising a deterministic physiologic rule base established through medical research. Patient care is improved by effecting change to the care environment by displaying risk factors and alerts as an intuitive color coded animation. The system presents a unified, contextually appropriate snapshot of the patient state including current and potential risk factors, and alerts of critical patient events to the operating room team without requiring any user intervention. To validate the efficacy of the system, a retrospective analysis focusing on the hypotension rules were performed. Results show that even with vigilant and highly trained clinicians, deviations from ideal patient care exist and it is here that the proposed system may allow more standardized and improved patient care and potentially outcomes.

    Several surgical treatments can be employed for the patients with neurological disorders, such as multiple sclerosis, Guillain-Barré syndrome, Parkinson's disease, amyotrophic lateral sclerosis, Alzheimer disease and spinal cord injury. It is possible that anesthesia related complications are induced in these neurologically complicated patients in the perioperative period. Respiratory dysfunction and autonomic nervous system dysfunction are most common in this population. Respiratory muscle weakness and bulbar palsy may cause aspiration pneumonia. Sometimes, postoperative ventilatory support is mandatory in these patients. Autonomic nervous system dysfunction may cause hypotension secondary to postural changes, blood loss, or positive airway pressure. Some therapeutic agents prescribed for neurological symptoms have drug interaction with anesthetic agents. Patients with motor neuron disease should be considered to be vulnerable to hyperkalemia in response to a depolarizing muscle relaxant. Although perioperative treatment guideline for most neurologic disorders has not been reported to lessen perioperative morbidity, knowledge of the clinical features and the interaction of common anesthetics with the drug therapy is important in planning intraoperative and postoperative management.

    Asthma is defined as a chronic inflammatory airway disease in response to a wide variety of provoking stimuli. Characteristic clinical symptoms of asthma are bronchial hyperreactivity, reversible airway obstruction, wheezing and dyspnea. Asthma presents a major public health problem with increasing prevalence rates and severity worldwide. Despite major advances in our understanding of the clinical management of asthmatic patients, it remains a challenging population for anesthesiologists in clinical practice. The anesthesiologist's responsibility starts with the preoperative assessment and evaluation of the pulmonary function. For patients with asthma who currently have no symptoms, the risk of perioperative respiratory complications is extremely low. Therefore, pulmonary function should be optimized preoperatively and airway obstruction should be controlled by using steroids and bronchodilators. Preoperative spirometry is a simple means of assessing presence and severity of airway obstruction as well as the degree of reversibility in response to bronchodilator therapy. An increase of 15% in FEV1 is considered clinically significant. Most asymptomatic persons with asthma can safely undergo general anesthesia with and without endotracheal intubation. Volatile anesthetics are still recommended for general anesthetic techniques. As compared to barbiturates and even ketamine, propofol is considered to be the agent of choice for induction of anesthesia in asthmatics. The use of regional anesthesia does not reduce perioperative respiratory complications in asymptomatic asthmatics, whereas it is advantageous in symptomatic patients. Pregnant asthmatic and parturients undergoing anesthesia are at increased risk, especially if regional anesthetic techniques are not suitable and prostaglandin and its derivates are administered for abortion or operative delivery. Bronchial hyperreactivity associated with asthma is an important risk factor of perioperative bronchospasm. The

    Obstetric analgesia and anesthesia have some specific aspects, which in particular are directly related to pathophysiological alterations during pregnancy and also to the circumstance that two or even more individuals are always affected by complications or therapeutic measures. This review article deals with some evergreens and hot topics of obstetric anesthesia and essential new knowledge on these aspects is described. The article summarizes the talks given at the 16th symposium on obstetric anesthesia organized by the Scientific Committee for Regional Anaesthesia and Obstetric Anaesthesia within the German Society of Anaesthesiology. The topics are in particular, special features and pitfalls of informed consent in the delivery room, challenges in education and training in obstetric anesthesia, expedient inclusion of simulation-assisted training and further education on risk minimization, knowledge and recommendations on fasting for the delivery room and cesarean sections, monitoring in obstetric anesthesia by neuraxial and alternative procedures, the possibilities and limitations of using ultrasound for lumbal epidural catheter positioning in the delivery room, recommended approaches in preparing peridural catheters for cesarean section, basic principles of cardiotocography, postoperative analgesia after cesarean section, the practice of early bonding in the delivery room during cesarean section births and the management of postpartum hemorrhage.

    Full Text Available Intradialytic hypotension (IDH remains an important cause of morbidity and mortality in chronic hemodialysis (HD patients and can be ameliorated by low temperature HD. Biofeed-back temperature-control device BTM® (Fresenius Medical Care, Germany was used for precision temperature measurement and to deliver isothermic (ITD or thermoneutral (TND dialysis. At stage one 24 stable dialysis patients were studied in terms of inlet blood temperature (IBT variation during sessions with normal (36,5 °С-ND and cold dialysate (35 °С-CD. IBT was increasing in both cases however the increase was significantly lower in CD. At stage two, 18 patients underwent programmed cooling during two ITD and two TND sessions. In TND high correlation (r = 0.66; р < 0.05 was observed between IBT increase and ultrafiltration rate. Keeping IBT stable during ITD required cons- tant decrease of dialysate temperature to 34.9 ± 0.2 °С at the end of session. At stage three, 19 IDH-prone patients were displaced from regular dialysis program to ITD. As a result,the decrease overall rate of IDH from 36.2 ± 1.1% to 11.3 ± 4,6% was observed. Conclusions: 1. The main mechanism of body temperature raise during HD is heat retention secondary to the compensatory response to loss of plasma volume, resulting in increase of the total peripheral resistance. 2. CD is effective for IDH prevention. 3. ITD is the optimal version of CD.

    2013-01-01

    Full Text Available Anesthetic management of laboring parturients with Arnold-Chiari type I malformation poses a difficult challenge for the anesthesiologist. The increase in intracranial pressure during uterine contractions, coughing, valsalva maneuvers, and expulsion of the fetus can be detrimental to the mother during the process of labor and delivery. No concrete evidence has implicated high cerebral spinal fluid pressure on maternal and fetal complications. The literature on the use of neuraxial techniques for managing parturients with Arnold-Chiari is extremely scarce. While most anesthesiologists advocate epidural analgesia for management of labor pain and spinal anesthesia for cesarean section, we are the first to report the use of combined spinal-epidural analgesia for managing labor pain in a pregnant woman with Arnold-Chiari type I malformation. Also, we have reviewed the literature and presented information from case reports and case series to support the safe usage of neuraxial techniques in these patients.

    Cardiac surgery represents a sub-group of patients at significantly increased risk of intraoperative awareness. Relatively few recent publications have targeted the topic of awareness in this group. The aim of this review is to identify areas of awareness research that may equally be extrapolated to cardiac anesthesia in the attempt to increase understanding of the nature and significance of this scenario and how to reduce it.

    This article will provide a review of mentorship in academic medicine. The review will include definitions and an overview of the evidence supporting the benefits, barriers, and structure of mentorship programmes in academic medicine and anesthesia. Finally, we will identify areas of further research. Mentorship in medicine has been increasingly recognized as a core component of training and career advancement in academic medicine. Mentoring provides many benefits to both mentor and mentee and facilitates the growth of academic departments by improving research productivity, faculty career satisfaction, recruitment, and educational performance. Mentorship programmes may be formal or informal and should include some form of mentor education. There are several barriers to successful mentorship including time constraints, limited availability of mentors, gender, minority status, and generational differences. These barriers may be overcome with improved awareness and sensitivity. Further investigation into the prevalence of mentorship and specific needs in our specialty are urgently required. Mentorship has been demonstrated to be an integral part of training and career development in academic medicine and benefits both mentees and mentors. Despite the promotion of mentorship in many academic anesthesia departments, little is published in the available literature supporting mentorship in anesthesia.

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

    Recently, some scholars suggested that it is important to keep a stablehemodynamic state and prevent the stress responses in geriatric patients undergoing total hip replacement (THR). We conducted this randomized prospective study to observe anesthetic potency of unilateral spinal anesthesia and stress response to it in geriatric patients during THR. We compared the effect of unilateral spinal and bilateral spinal on inhibition of stress response through measuring Norepinephrine (NE), epinephrine (E) and cortisol (CORT). Plasma concentrations of NE, E and CORT were determined in blood samples using ELISA (enzyme-linked immunosorbent assays) at three time points: To (prior to anesthesia) T1 (at the time point of skin closure), T2 (twenty-four hours after the operation). Sixty patients were randomly divided into two groups: group A (unilateral spinal anesthesia) and group B (conventional bilateral spinal anesthesia). 7.5tymg of hypobaric bupivacaine were injected into subarachnoid cavity at group A and 12mg hypobaric bupivacaine were given at group B. The onset time of sensory and motor block, loss of pinprick sensation, degree of motor block, regression of sensory and motor blocks and hemodynamic changes were also recorded. These data were used to evaluate anesthetic potency of spinal anesthesia. The results of this experiment show that unilateral spinal anesthesia can provide restriction of sensory and motor block, minimize the incidence of hypotension and prevent the stress responses undergoing THR. It is optimal anesthesia procedure for geriatric patients by rapid subarachnoid injection of small doses of bupivacaine.

    2012-01-01

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

    Literature on the use of epinephrine in the treatment of anaphylaxis during anesthesia is very limited. The objective of this study was to investigate how often epinephrine is used in the treatment of suspected anaphylaxis during anesthesia in Denmark and whether timing of treatment is important. A retrospective study of 270 patients investigated at the Danish Anaesthesia Allergy Centre after referral due to suspected anaphylaxis during anesthesia was performed. Reactions had been graded by severity: C1, mild reactions; C2, moderate reactions; C3, anaphylactic shock with circulatory instability; C4, cardiac arrest. Use of epinephrine, dosage, route of administration, and time between onset of circulatory instability and epinephrine administration were noted. A total of 122 (45.2%) of referred patients had C3 or C4 reactions; of those, 101 (82.8%) received epinephrine. Route of administration was intravenous in 95 (94%) patients. Median time from onset of reported hypotension to treatment with epinephrine was 10 min (range, 1-70 min). Defining epinephrine treatment less than or equal to 10 min after onset of hypotension as early, and more than 10 min as late, infusion was needed in 12 of 60 patients (20%) treated early versus 12 of 35 patients (34%) treated late (odds ratio, 2.09) (95% confidence interval, 0.81-5.35). Anaphylaxis may be difficult to diagnose during anesthesia, and treatment with epinephrine can be delayed as a consequence. Anaphylaxis should be considered and treated in patients with circulatory instability during anesthesia of no apparent cause who do not respond to the usual treatments.

    Identify predictors of cardiogenic etiology among emergency department (ED) patients with hypotension, and use these predictors to create a clinical tool to discern cardiogenic etiology of hypotension. This secondary analysis evaluated a prospective cohort of consecutive patients with hypotension in an urban, academic, tertiary care ED from November 2012 to September 2013. We included adults with hypotension, defined as a new vasopressor requirement, systolic blood pressure (SBP)  0.1 ng/mL (37.5, 7.1-198.2), electrocardiographic ischemia (8.9, 4.0-19.8), history of heart failure (2.0, 1.1-3.3), and absence of fever (4.5, 2.3-8.7) (area under the curve [AUC] = 0.83). The prediction score created from these predictors yielded 78% sensitivity and 77% specificity for cardiogenic etiology (AUC = 0.827). Clinical predictors offer reasonable ED screening sensitivity for cardiogenic hypotension, while demonstrating sufficient specificity to facilitate early cardiac interventions.

    We describe the risk management of pediatric anesthesia. The most important risk management of pediatric anesthesia is airway and temperature management. Neonates and infants easily become hypoxic due to their insufficient functional residual capacity. Therefore airway management is most important not only during induction of anesthesia but also during maintenance of anesthesia and extubation. The management of patients' temperature, including control of room temperature should be taken into consideration. In addition, careful attention should be paid not to introduce air bubbles in any lines, especially in patients with congenital heart diseases.

  1. Anesthesia for ambulatory anorectal surgery.

    2004-01-01

    The prevalence of minor anorectal diseases is 4-5% of adult Western population. Operations are performed on ambulatory or 24-hour stay basis. Requirements for ambulatory anesthesia are: rapid onset and recovery, ability to provide quick adjustments during maintenance, lack of intraoperative and postoperative side effects, and cost-effectiveness. Anorectal surgery requires deep levels of anesthesia. The aim is achieved with 1) regional blocks alone or in combination with monitored anesthesia care or 2) deep general anesthesia, usually with muscle relaxants and tracheal intubation. Modern general anesthetics provide smooth, quickly adjustable anesthesia and are a good choice for ambulatory surgery. Popular regional methods are: spinal anesthesia, caudal blockade, posterior perineal blockade and local anesthesia. The trend in regional anesthesia is lowering the dose of local anesthetic, providing selective segmental block. Adjuvants potentiating analgesia are recommended. Postoperative period may be complicated by: 1) severe pain, 2) urinary retention due to common nerve supply, and 3) surgical bleeding. Complications may lead to hospital admission. In conclusion, novel general anesthetics are recommended for ambulatory anorectal surgery. Further studies to determine an optimal dose and method are needed in the group of regional anesthesia.

    Anesthesia information management system workstations in the anesthesia workspace that allow usage of non-record-keeping applications could lead to distraction from patient care. We evaluated whether non-record-keeping usage of the computer workstation was associated with hemodynamic variability and aberrancies. Auditing data were collected on eight anesthesia information management system workstations and linked to their corresponding electronic anesthesia records to identify which application was active at any given time during the case. For each case, the periods spent using the anesthesia information management system record-keeping module were separated from those spent using non-record-keeping applications. The variability of heart rate and blood pressure were also calculated, as were the incidence of hypotension, hypertension, and tachycardia. Analysis was performed to identify whether non-record-keeping activity was a significant predictor of these hemodynamic outcomes. Data were analyzed for 1,061 cases performed by 171 clinicians. Median (interquartile range) non-record-keeping activity time was 14 (1, 38) min, representing 16 (3, 33)% of a median 80 (39, 143) min of procedure time. Variables associated with greater non-record-keeping activity included attending anesthesiologists working unassisted, longer case duration, lower American Society of Anesthesiologists status, and general anesthesia. Overall, there was no independent association between non-record-keeping workstation use and hemodynamic variability or aberrancies during anesthesia either between cases or within cases. Anesthesia providers spent sizable portions of case time performing non-record-keeping applications on anesthesia information management system workstations. This use, however, was not independently associated with greater hemodynamic variability or aberrancies in patients during maintenance of general anesthesia for predominantly general surgical and gynecologic procedures.

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

  5. Epidural Labor Analgesia and Maternal Fever.

    2017-06-01

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

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

    Background Intracranial structural dislocation in spontaneous intracranial hypotension (SIH) can be measured by various intracranial angles and distances. We aimed to identify the clinical significance of structural dislocation in relation to treatment outcome in patients with SIH. Methods In this retrospective analysis, we identified patients with SIH who received an epidural blood patch (EBP) at Samsung Medical Center from January 2005 to March 2015. Structural dislocation in pretreatment MRIs of SIH patients was assessed by measuring tonsillar herniation, mamillopontine distance, the angle between the vein of Galen and straight sinus (vG/SS angle), the pontomesencephalic angle, and the lateral ventricular angle. After the first EBP, poor response was defined as the persistence of symptoms that prompted a repeat EBP. Results Out of the 95 patients included, 31 (32.6%) showed poor response. Among the radiological markers of structural dislocation, the vG/SS angle was associated with poor response (49.82 ± 16.40° vs 66.58 ± 26.08°, p = 0.002). Among clinical variables, premorbid migraine ( p = 0.036) was related to poor response. In multivariate analysis, reduced vG/SS angle was independently associated with poor response (OR 1.04 [95% CI 1.01 - 1.07] per 1° decrease, p = 0.006). In 23 patients who underwent MRI after successful treatment, the vG/SS angle significantly increased after the EBP ( p < 0.001, by paired t-test), while two patients with aggravation or recurrence showed a further reduction of their vG/SS angles. Conclusions Intracranial structural dislocation, measured by the vG/SS angle, is associated with poor response to the first EBP in patients with SIH. Successful treatment can reverse the structural dislocation.

  10. Evaluation and treatment of hypotension in the preterm infant.

    2012-01-31

    A large proportion of very preterm infants receive treatment for hypotension. The definition of hypotension is unclear, and, currently, there is no evidence that treating it improves outcomes or, indeed, which treatment to choose among the available alternatives. Assessment of circulatory adequacy of the preterm infant requires a careful clinical assessment and may also require ancillary investigations. The most commonly used interventions, fluid boluses and dopamine, are problematic: fluid boluses are statistically associated with worse clinical outcomes and may not even increase blood pressure, whereas dopamine increases blood pressure mostly by causing vasoconstriction and may decrease perfusion. For neither intervention is there any reliable data showing clinical benefit. Prospective trials of intervention for hypotension and circulatory compromise are urgently required.

    , 105 and 120 mins., i.e. (every 5 mins. for 15 mins. and then every 15 mins. for 2 hrs. until the next request for analgesia. After positioning the patient in supine position, onset of analgesia and dermatome level were checked by loss of sensation to pinprick, time of onset and degree of motor blockade was checked by Bromage classification. VAS pain scores for all patients immediately before and after 15 mins. of the procedure at the next request for analgesia. Vitals were recorded and study was terminated. Continuation of epidural analgesia was done with 0.125% bupivacaine + 2 µg fentanyl in 10 mL. Monitoring - mother’s vital parameters, progress of labour, efficacy of analgesia and foetal welfare were watched in coordination with attending obstetrician. Pulse, NIBP, SpO2, respiratory rate were recorded before and after the start of procedure and every 5 mins. for first 15 mins. and then every 15 mins. for 2 hrs. If bradycardia occurred at any time (<60 bts./mins., Inj. Glycopyrrolate 0.2 mg was given. If hypotension occurred, then it was treated appropriately with IV fluids and vasopressor. If pruritus occurred, it was treated with pheniramine. Sensory blockade assessed by pinprick and motor blockade was assessed by Bromage scale. Statistical Analysis- In the present study, results are given as mean±standard deviation and range values for continuous data. Students test was used to compare the two groups, categorical data are expressed as number and percentages and difference between the groups was compared by chi-square test. A p value of 0.05 or less was set for statistical significance.RESULTS Maternal hypotension of 15% was noted in both groups, which was statistically significant. Onset of sensory analgesia in seconds showed a standard deviation of 38.12 with a mean difference of 47 seconds between the two groups was found to be statistically highly significant with a p value of <0.001.

    To assess the effects of dopamine and dobutamine on the blood pressure of isoflurane-anesthetized Hispaniolan Amazon parrots (Amazona ventralis). 8 Hispaniolan Amazon parrots. A randomized crossover study was conducted. Each bird was anesthetized (anesthesia maintained by administration of 2.5% isoflurane in oxygen) and received 3 doses of each drug during a treatment period of 20 min/dose. Treatments were constant rate infusions (CRIs) of dobutamine (5, 10, and 15 μg/kg/min) and dopamine (5, 7, and 10 μg/kg/min). Direct systolic, diastolic, and mean arterial pressure measurements, heart rate, esophageal temperature, and end-tidal partial pressure of CO(2) were recorded throughout the treatment periods. Mean ± SD of the systolic, mean, and diastolic arterial blood pressures at time 0 (initiation of a CRI) were 132.9 ± 22.1 mm Hg, 116.9 ± 20.5 mm Hg, and 101.9 ± 22.0 mm Hg, respectively. Dopamine resulted in significantly higher values than did dobutamine for the measured variables, except for end-tidal partial pressure of CO(2). Post hoc multiple comparisons revealed that the changes in arterial blood pressure were significantly different 4 to 7 minutes after initiation of a CRI. Overall, dopamine at rates of 7 and 10 μg/kg/min and dobutamine at a rate of 15 μg/kg/min caused the greatest increases in arterial blood pressure. Dobutamine CRI at 5, 10, and 15 μg/kg/min and dopamine CRI at 5, 7, and 10 μg/kg/min may be useful in correcting severe hypotension in Hispaniolan Amazon parrots caused by anesthesia maintained with 2.5% isoflurane.

    Full Text Available Anesthetizing an intellectually disabled patient is a challenge due to lack of cognition and communication which makes perioperative evaluation difficult. The presence of associated medical problems and lack of cooperation further complicates the anesthetic technique. An online literature search was performed using keywords anesthesia, intellectually disabled, and mentally retarded and relevant articles were included for review. There is scarcity of literature dealing with intellectually disabled patients. The present review highlights the anesthetic challenges, their relevant evidence-based management, and the role of caretakers in the perioperative period. Proper understanding of the associated problems along with a considerate and unhurried approach are the essentials of anesthetic management of these patients.

    Full Text Available Anesthesia for thoracoscopy is based on one lung ventilation. Lung separators in the airway are essential tools. An anatomical shunt as a result of the continued perfusion of a non-ventilated lung is the principal intraoperative concern. The combination of equipment, technique and process increase risks of hypoxia and dynamic hyperinflation, in turn, potential factors in the development of an unusual form of pulmonary edema. Analgesia management is modelled on that shown effective and therapeutic for thoracotomy. Perioperative management needs to reflect the concern for these complex, and complicating, processes to the morbidity of thoracoscopic surgery.

    Fucosidosis is a rare, autosomal recessive lysosomal storage disorder caused by a severe deficiency of alpha -L-fucosidase. Patients usually have some problems with glycoprotein storage in the brain and other organs and some structural abnormalities that need special consideration in anesthesia. It has 2 types, the early onset or infantile and the juvenile. Here we present 8-year-old girl with deformities in the maxillofacial region, with big tongue, small and retracted chin, saddle nose and short neck that could not be extended, causing difficult intubation and congenital cardiac problems requiring a special anesthetic strategy.

    A strong tendency toward body enhancement and body forming in western industrial societies makes it more likely for each anesthesiologist to get involved in the care of bodybuilders. These patients quite frequently consume androgenic anabolic steroids, human growth hormone and other drugs or substances which are believed to accelerate muscle gain. Cardiovascular, hepatic, psychiatric, hormonal and infectious side effects or complications are common and rarely monitored by health care professionals. The anesthesia risk is not exactly known but seems to be determined mainly by cardiovascular events like myocardial ischemia and dysrhythmias.

    Full Text Available We report a case of inadvertent hypothermia leading to severe hypotension resistant to high dose vasopressors, which responded to temperature correction in a patient undergoing spinal instrumentation surgery. A 60-year-old female developed severe hypotension during spinal instrumentation surgery. After review of all factors it was found to be secondary to hypothermia. The patient did not respond to high dose vasopressors. However, when normothermia was restored she recovered uneventfully. Patients undergoing lengthy spinal procedures in prone position are vulnerable to develop hypothermia and consequent cardiovascular depression so adequate measures should be taken to prevent hypothermia.

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

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

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

    2015-01-01

    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.

    The effects of halothane anesthesia on coronary circulation and cardiac work were studied in normovolemic and hypovolemic dogs, with the aid of the radioactive microsphere technique. During normovolemia, halothane depressed the heart rate, cardiac output, arterial mean blood pressure and left ventricular work, with a simultaneous decrease in the coronary blood flow. During moderate hypovolemia, the arterial blood pressure was reduced as well as the coronary blood flow; whereas during hemorrhagic hypotension (severe hypovolemia), the arterial blood pressure was slightly increased and the coronary blood flow was unchanged with a reduced heart rate and increased stroke volume.

    2017-03-01

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

    inferiores. 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.

    Difficult airway, a scenario with potentially life threatening outcome, is routinely encountered by an anesthesiologist leaving him with the dilemma of whether to use regional anesthesia (RA) or general anesthesia. Our study aims to look into this problem. The literature search was performed in the Google, PubMed, and Medscape using key words "regional anesthesia, difficult airway, pregnancy, ventilation, intubation, epidural anesthesia, nerve blocks." More than 38 free full articles and books published from the year 1987 to 2014 were retrieved and studied. At first sight, RA may appear to offer an ideal solution as it helps to avoid the problem of difficult airway. However, the possibility of a total spinal block, failed or incomplete RA, local anesthetic toxicity or unforeseen surgical complication may make it imperative that the airway is secured. The correct decision can only be made by the anesthetist when all the relevant clinical information is taken into account. It is also important to ensure that before considering RA in a patient of difficult airway, an anesthesiologist must have a preformulated strategy for intubation.

    Mianserin is thought to exert little effect on the cardiovascular system. In fact its safety in comparison with tricyclic drugs is high. Various experiments gave varying results as for the influence of the drug on arterial blood pressure in people and animals. Therefore, a study was undertaken in Wistar rats to evaluate interactions of mianserin administered intraperitoneally as a single dose, and for 21 days with 3 hypotensive drugs showing different mechanism of action (propranolol, enalapril, prazosine). The systolic, diastolic and mean blood pressure was measured with a LETICA apparatus. The results of the study revealed that administration of mianserin in normotensive rats leads to a short-term decrease in blood pressure and significantly enhanced the hypotensive effect of prazosine. Repeated doses of mianserin lead to a temporary increase in blood pressure after 2 weeks of administration. Single and repeated administration of mianserin did not change the hypotensive effect of propranolol and enalapril. Three-week therapy with mianserin significantly enhanced the hypotensive effect of prazosine.

    Central methysergide prevents renal sympathoinhibition and bradycardia during hypotensive hemorrhage. Mean arterial pressure (MAP), heart rate (HR), and renal sympathetic nerve activity (RSNA) were measured in conscious rats during either hemorrhage or cardiopulmonary receptor stimulation with phenylbiguanide (PBG) after intracerebroventricular injection of the 5-HT1/5-HT2-receptor antagonist, methysergide (40 microg). Progressive hemorrhage caused an initial rise (109 +/- 33%) followed by a fall in RSNA (-60 +/- 7%) and a fall in HR (-126 +/- 7 beats/min). Methysergide delayed the hypotension and prevented both the sympathoinhibitory and bradycardic responses to hemorrhage. Systemic 5-HT3-receptor blockade did not influence responses to hemorrhage. The PBG infusion caused transient depressor(-25 +/- 6 mmHg), bradycardic (-176 +/- 40 beats/min), and renal sympathostimulatory (182 +/-47% baseline) responses that were not affected by central methysergide (-20 +/- 6 mmHg, -162 +/- 18 beats/min, 227 +/- 46% baseline). These data indicate that a central serotonergic receptor-mediated component contributes to the sympathoinhibitory and bradycardic responses to hypotensive hemorrhage in conscious rats. Furthermore, the same central 5-HT-receptor populations involved in reflex responses to hypotensive hemorrhage probably do not mediate the sympathoinhibitory response to cardiopulmonary chemosensitive 5-HT3 receptors.

    INTRODUCTION: It is thought that patients with cardiomyopathy have an increased risk of cardiac arrest on induction of anesthesia, but there is little available data. The purpose of this study was to identify the incidence and potential risk factors for cardiac arrest upon induction of anesthesia in children with cardiomyopathy in our institution. METHODS: A retrospective chart review was performed. Eligible patients included patients admitted between 1998 and 2008 with the International Statistical Classification of Disease code for cardiomyopathy (ICD-9 code 425) who underwent airway intervention for sedation or general anesthesia in the operating room, cardiac diagnostic and interventional unit (CDIU) or intensive care unit. Patients undergoing emergency airway intervention following cardiovascular collapse were excluded. For each patient, we recorded patient demographics, disease severity, anesthesia location, and anesthetic technique. RESULTS: One hundred and twenty-nine patients with cardiomyopathy underwent a total of 236 anesthetic events, and four cardiac arrests were identified. One was related to bradycardia (HR<60), two were attributed to bradycardia in association with severe hypotension (systolic blood pressure<45), and the fourth arrest was related to isolated severe hypotension. Two occurred in the operating suite and two in the CDIU. There was no resulting mortality. One patient progressed to heart transplantation. Multiple combinations of anesthetic drugs were used for induction of anesthesia. CONCLUSION: We performed a review of the last 10 years of anesthesia events in children with cardiomyopathy. We report four cardiac arrests in two patients and 236 anesthetic events (1.7%). To the best of our knowledge, this is the largest review of these patients to date but is limited by its retrospective nature. The low cardiac arrest incidence prevents the identification of risk factors and the development of a cardiac arrest risk predictive clinical

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

This study was designed to compare spinal anesthesia using hyperbaric bupivacaine given as a conventional dose by lumbar puncture or as a low-dose by thoracic puncture.Methods: A total of 140 patients with symptomatic gallstone disease were randomized to undergo laparoscopic cholecystectomy with low-pressure CO2 pneumoperitoneum under spinal anesthesia using either conventional lumbar spinal anesthesia (hyperbaric bupivacaine 15 mg and fentanyl 20 mg or low-dose thoracic spinal anesthesia (hyperbaric bupivacaine 7.5 mg and fentanyl 20 µg. Intraoperative parameters, postoperative pain, complications, recovery time, and patient satisfaction at follow-up were compared between the two treatment groups.Results: All procedures were completed under spinal anesthesia, with no cases needing conversion to general anesthesia. Values for time for block to reach the T3 dermatomal level, duration of motor and sensory block, and hypotensive events were significantly lower with low-dose bupivacaine. Postoperative pain was higher for low-dose hyperbaric bupivacaine at 6 and 12 hours. All patients were discharged after 24 hours. Follow-up 1 week postoperatively showed all patients to be satisfied and to be keen advocates of spinal anesthesia.Conclusion: Laparoscopic cholecystectomy can be performed successfully under spinal anesthesia. A small dose of hyperbaric bupivacaine 7.5 mg and 20 µg fentanyl provides adequate spinal anesthesia for laparoscopy and, in comparison with hyperbaric bupivacaine 15% and fentanyl 20 µg, causes markedly
