Effective use of postoperative incentive spirometry improves patient outcomes but is limited by pain after thoracic and upper abdominal surgery. Thoracic epidurals are frequently used to provide analgesia and attenuate postoperative pulmonary dysfunction. We hypothesized that, in patients with thoracic epidurals for thoracic and abdominal surgery, high pain scores would be associated with poorer incentive spirometry performance, even when accounting for other variables. Retrospective study of 468 patients who underwent upper abdominal or thoracic surgery using postoperative thoracic epidural analgesia between June 1, 2009, and August 31, 2013, at a single tertiary academic center. The association between incentive spirometry performance and pain was assessed as the primary outcome. Other independent predictors of incentive spirometry performance were also identified. Postoperative incentive spirometry performance was found to be inversely proportional to pain score, which correlated significantly stronger with deep breathing pain compared with pain at rest (-0.33 vs -0.14 on postoperative day 1; -0.23 vs -0.12 on postoperative day 2). Pain with deep breathing was independently associated with poorer incentive spirometry performance in the multivariable linear regression model (P spirometry performance could be used as another indicator of thoracic epidural efficacy. This may be particularly useful in patients reporting high pain scores postoperatively.

In a prospective study we compared the surgical outcome, length of hospital stay, complications and patient satisfaction for patients undergoing lumbar microdiscectomy (LM) under spinal anaesthesia (SA) in the sitting position (23 patients) to those of another cohort who underwent LM under general anaesthesia (GA) in the prone or genu-pectoral position during the same time period (238 patients). We aimed to determine: (i) if epidural anaesthesia is safe for lumbar microdiscectomy; and (ii) if placing the patient in a sitting position confers an advantage in performing the operation. For all patients we calculated the time from the end of the operation to the first spontaneous urination and to the first administration of analgesic drugs. Before being discharged, patients were asked to give an opinion on the quality of analgesia obtained by epidural anaesthesia and on the sitting position used. No patient had any complications linked to epidural anaesthesia and only one patient experienced a small dural tear as a surgical complication. Twenty of 23 patients expressed satisfaction with the level of analgesia obtained and only three considered it poor. All patients found the sitting position comfortable. Advantages of the sitting position for surgery include better comfort for the patient, potential to recreate a load condition similar to the one that takes place during orthostasis and a "cleaner" operative field that uses gravity to drain blood. Of greatest concern is the possibility of the patient developing a dural tear and subsequent leaking of cerebrospinal fluid, which could also be a source of surgical complications. Currently, epidural anaesthesia allows a reduction in anaesthetic and surgical times, anaesthetic complications and, consequently, hospitalization period. Further analysis of the sitting position for the patient during surgery is required to fully assess the advantages and disadvantages of this method. Copyright © 2010 Elsevier Ltd. All rights

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.

Full Text Available OBJECTIVE: The aim of this study was to evaluate the effects of general and epidural anaesthesia in newborn’s stres hormones, blood gases, and Apgar scores in elective cesarean section. MATERIALS-METHODS: 50 patients in ASA II (American Society of Anesthesiology class who would undergo elective cesarean section in University of Kahramanmaras Sutcuimam, Department of Anaesthesiology and Reanimation included in the study and randomized into two equal groups (General anaesthesia: Group G and Epidural anaesthesia: Group E. In both groups, newborn stres hormones (TSH, cortisol, and insulin, blood gases, and Apgar scores were studued. All patients received famotidine and granisetron iv 30 min before operations in premedication room. In the general anaesthesia group; aritmal, propofol, and succinylcholine was used for induction and muscle relaxation. Following the induction, positive pressure ventilation of the lungs was started immediately using a 50% N2O + O2 mixture. After delivery of the baby, anaesthesia and muscle relaxation was maintained by 50% N2O +O2, 0,5-1% MAC isoflurane, and cisatracurium. In the epidural anaesthesia group; epidural anaesthesia was performed with 0,375% bupivacaine. The epidural needle inserted through L2-3 or L3-4 interspace. After achieving T4-5 neural blockade, the operation was started. Blood samples for newborn stres hormones and blood gases were taken from umblical vein. The Apgar scores were recorded at 1 min and again at 5 min after the delivery by same person. RESULTS: There were no differences in newborn stress hormones between two groups. In newborn blood gases analyses, only SO2 changes were statistically significant between two groups. There were no differences in newborn Apgar scores between two groups. CONCLUSION: With these results, we concluded that each of the general and epidural anaesthesia techniques have similar effects on newborn blood gases, stress hormones and Apgar scores and can be acceptable

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.

The effects of oral carbohydrate solutions, ingested 2 h prior to operation, on stress response were studied in patients undergoing general or epidural anaesthesia. The study was performed on 80 ASA I-II adult patients undergoing elective total hip replacement, which were randomized to four groups (n=20). Group G patients undergoing general anaesthesia fasted for 8 h preoperatively; Group GN patients undergoing general anaesthesia drank oral carbohydrate solutions preoperatively; Group E patients undergoing epidural anaesthesia fasted for 8 h and Group EN patients undergoing epidural anaesthesia drank oral carbohydrate solutions preoperatively. Groups GN and EN drank 800 mL of 12.5% oral carbohydrate solution at 24:00 preoperatively and 400 mL 2 h before the operation. Blood samples were taken for measurements of glucose, insulin, cortisol and IL-6 levels. The effect of preoperative oral carbohydrate ingestion on blood glucose levels was not significant. Insulin levels 24 h prior to surgery were similar; however, insulin levels measured just before surgery were 2-3 times higher in groups GN and EN than in groups G and E. Insulin levels at the 24(th) postoperative hour in epidural groups were increased compared to those at basal levels, although general anaesthesia groups showed a decrease. From these measurements, only the change in Group EN was statistically significant (poral carbohydrate nutrition did not reveal a significant effect on surgical stress response.

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.

The purpose of the study is to examine the perioperative dynamics of strategic blood oxygen transport indicators: delivery (DO2), consumption (VO2), the coefficient of oxygen uptake (CUO2) and their composition, as well as the dynamics of blood lactate indicators in patients with ischaemic heart disease (IHD) who underwent surgery under cardiopulmonary bypass with high thoracic epidural anaesthesia (HTEA) as the main component of anesthesia. Research was conducted in 30 patients with a critical degree of operational risk, during the correction of post-infarction heart aneurysmn using the V. Dor method in combination with coronary artery bypass grafting. The strategic blood oxygen transport indicators (delivery, consumption and the oxygen uptake coefficient) showed a statistically significant decrease compared to the physiological norm and to the initial data at two points of the research: the intubation of the trachea and during cardiopulmonary bypass. The system components of oxygen were influenced at problematic stages by the dynamics of SvO2 (increase), AVD (decrease), hemodilution withe fall of the HIb- in the process of JR in the persence of superficial hypothermia.

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

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

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 Background and Aims: Neuraxial anaesthesia has recently become popular for percutaneous nephrolithotomy (PCNL. We conducted a study comparing general anaesthesia (GA with segmental (T6–T12 epidural anaesthesia (SEA for PCNL with respect to anaesthesia and surgical characteristics. Methods: Ninety American Society of Anesthesiologists Physical Status-I and II patients undergoing PCNL randomly received either GA or SEA. Overall patient satisfaction was the primary end point. Intraoperative haemodynamics, epidural block characteristics, post-operative pain, time to rescue analgesic, total analgesic consumption, discharge times from post-anaesthesia care unit, surgeon satisfaction scores and stone clearance were secondary end points. Parametric data were analysed by Student's t-test while non-parametric data were compared with Mann–Whitney U-test. Results: Group SEA reported better patient satisfaction (P = 0.005. Patients in group GA had significantly higher heart rates (P = 0.0001 and comparable mean arterial pressures (P = 0.24. Postoperatively, time to first rescue analgesic and total tramadol consumption was higher in Group GA (P = 0.001. Group SEA had lower pain scores (P = 0.001. Time to reach Aldrete's score of 9 was shorter in group SEA (P = 0.0001. The incidence of nausea was higher in group GA (P = 0.001; vomiting rates were comparable (P = 0.15. One patient in group SEA developed bradycardia which was successfully treated. Eight patients (18% had hypertensive episodes in group GA versus none in group SEA (P = 0.0001. One patient in GA group had pleural injury and was managed with intercostal drain. Stone clearance and post-operative haemoglobin levels were comparable in both groups. Conclusion: PCNL under SEA has a role in selected patients, for short duration surgery and in expert hands.

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.

Full Text Available Background and objectives: Only few reports in literature have pointed out to the possibility of a cranial subdural haematoma formation associated with dural puncture during spinal or epidural analgesia. We herein describe such a rare case who was diagnosed to have acute subdural haematoma after combined spinal–epidural anaesthesia used in labour. Case report: A 34-year-old, primigravid women with a gestation of 38 weeks underwent caesarean section under combined spinal–epidural anaesthesia and gave birth to a healthy boy. Thirty-two hours after delivery, her moderate headache progressed to a severe headache associated with nausea and vomiting and later was more complicated with a generalized tonic–clonic seizure and ensuing lethargy. Computed tomography of the brain demonstrated a right-sided fronto-temporo-parietal acute subdural haematoma with diffuse cerebral oedema. She underwent urgent FTP craniotomy and evacuation of the haematoma. Early postoperative cranial computed tomography showed a clean operative site. Eight days after subdural haematoma surgery, she became lethargic again, and this time cranial computed tomography disclosed an extradural haematoma under the bone flap for which she had to undergo surgery again. Two days later, she was discharged home with Karnofsky performance score of 90/100. At follow-up exam, she was neurologically intact and her cranial computed tomography and magnetic resonance were normal. Conclusions: As conclusion, with the use of this combined spinal–epidural anaesthesia, it should be kept in mind that headache does not always mean low pressure headache associated with spinal anaesthesia and that a catastrophic complication of subdural haematoma may also occur.

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

Two patients with spontaneous epidural hematoma of the thoracic spine are presented. The magnetic resonance (MR) examination performed within the first hours following the onset of symptoms demonstrated an epidural elongated lesion impinging on the spinal cord, compatible with hematoma. In one of the patients this finding was surgically confirmed. The second patient improved under steroid treatment. The MR findings were highly suggestive of the pathological nature of the lesion. The MR examination should replace other diagnostic procedures, such as computerised tomography (CT) and myelography. (orig.)

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.

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)

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.

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

The uteroplacental blood flow was measured before and during epidural anaesthesia for caesarean section in 11 woman. The blood flow was measured with dynamic placental scintigraphy. After an i.v. injection of indium-113m chloride, the gamma radiation over the placenta was recorded with a computer-linked scintillation camera. The uteroplacental blood flow could be calculated from the isotope accumulation curve. The anaesthesia was performed with bupivacaine plain 0.5%, 18-22 ml and a preload of a balanced electrolyte solution 10 ml/kg b.w. was given. The placental blood flow decreased in eight patients and increased in three with a median change of -21%, not being statistically significant. No correlation between maternal blood pressure and placental blood flow was found. (author).

Twenty patients undergoing elective cholecystectomy via a subcostal incision were randomized in a double-blind study to either thoracic paravertebral blockade with bupivacaine 0.5% (15 ml followed by 5 ml/h) or thoracic epidural blockade with bupivacaine 7 ml 0.5% + morphine 2 mg followed by 5 ml...... by forced vital capacity, forced expiratory volume and peak expiratory flow rate decreased about 50% postoperatively in both groups. In conclusion, the continuous paravertebral bupivacaine infusion used here was insufficient as the only analgesic after cholecystectomy. In contrast, epidural blockade...... with combined bupivacaine and low dose morphine produced total pain relief in six of ten patients....

Full Text Available Quadriplegia following spinal anaesthesia due to spinal epidural haematoma is a rare but critical complication that usually occurs within 24 hours to a few days of the procedure. I report a case of a 32 year old male who underwent Uretero - Renal Scopy (URS and double ‘J’ (DJ stenting for right ureteric calculus under spinal anaesthesia. The patient was on nonsteroidal anti - inflammatory agents (NSAIDS and oral Prednisolone for sero - negative rheumatoid arthritis. The preoperative investigations were normal. About four hours after surgery, the patient developed paraesthesia of lower limbs, a little later paraplegia and gradually quadriplegia within 12 to 15 hours of surgery. Magnetic Resonance Imaging (MRI revealed an extensive spinal epidural haematoma and cord oedema extending from C2 to L5 vertebrae. In consultation with neuro - surgeon, the patient was treated conservatively, while awaiting for the results of coagulation profile, which proved to be Haemophilia. By the end of 2nd and 3rd postoperative day, the upper limbs showed signs of recovery and within a week’s time, both the upper limbs regained normal power and tone. The lower limbs showed sensory as well as motor recovery by 3 rd week and about total recovery to normalcy by 6 weeks. Residual paresis remained in left lower limb. The patient was sent for physiotherapy and he recovered completely by 9 months

It is difficult to evaluate the significant findings of epidural hematoma in magnetic resonance images (MRIs) obtained immediately after thoracic posterior screw fixation (PSF). Prospectively, immediate postoperative MRI was performed in 10 patients who underwent thoracic PSF from April to December 2013. Additionally, we retrospectively analyzed the MRIs from 3 patients before hematoma evacuation out of 260 patients who underwent thoracic PSF from January 2000 to March 2013. The MRI findings of 9 out of the 10 patients, consecutively collected after thoracic PSF, showed neurologic recovery with a well-preserved cerebrospinal fluid (CSF) space and no prominent hemorrhage. Even though there were metal artifacts at the level of the pedicle screws, the preserved CSF space was observed. In contrast, the MRI of 1 patient with poor neurologic outcome demonstrated a typical hematoma and slight spinal cord compression and reduced CSF space. In the retrospective analysis of the 3 patients who showed definite motor weakness in the lower extremities after their first thoracic fusion surgery and underwent hematoma evacuation, the magnetic resonance images before hematoma evacuation also revealed hematoma compressing the spinal cord and diminished CSF space. This study shows that epidural hematomas can be detected on MRI performed immediately after thoracic fixation surgery, despite metal artifacts and findings such as hematoma causing spinal cord compression. Loss of CSF space should be considered to be associated with neurologic deficit. Copyright © 2017 Elsevier Inc. All rights reserved.

The effect of thoracic (T7-8) epidural etidocaine 1.5%, 9 ml, and continuous per- and postoperative epidural infusion of etidocaine 1.5%, 4 ml/h, on early (less than 500 ms) somatosensory evoked potentials (SEPs), and cortisol and glucose in plasma during cholecystectomy, was examined in ten...... stimulation at the L1, T10 or T6 dermatomal level (P greater than 0.09). SEPs were abolished in only two patients at T6, and no patient had SEPs abolished at T10 or L1. The plasma concentrations of cortisol and glucose were significantly increased 20 min after surgical incision and remained increased...... throughout the study. No correlation was found between the block-induced decrease in the peak-to-peak amplitude at T6 or T10 and increase in plasma cortisol, except for a negative correlation at T10 and the initial increase in cortisol (Rs = 0.72, P = 0.03). In conclusion, thoracic epidural administration...

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

The use of ultrasound (US) scanning to assess the depth of epidural space to prevent neurological complications is established in current practice. In this study, we hypothesised that pre-puncture US scanning for estimating the depth of epidural space for thoracic epidurals is comparable between transverse median (TM) and paramedian sagittal oblique (PSO) planes. We performed pre-puncture US scanning in 32 patients, posted for open abdominal surgeries. The imaging was done to detect the depth of epidural space from skin (ultrasound depth [UD]) and needle insertion point, in parasagittal oblique plane in PSO group and transverse median plane in TM group. Subsequently, epidural space was localised through the predetermined insertion point by 'loss of resistance' technique and needle depth (ND) to the epidural space was marked. Correlation between the UD and actual ND was calculated and concordance correlation coefficient (CCC) was used to determine the degree of agreement between UD and ND in both the planes. The primary outcome, i.e., the comparison between UD and ND, done using Pearson correlation coefficient, was 0.99 in both PSO and TM groups, and the CCC was 0.93 (95% confidence interval [95% CI]: 0.81-0.97) and 0.90 (95% CI: 0.74-0.96) in PSO and TM groups respectively, which shows a strong positive association between UD and ND in both groups. The use of pre-puncture US scanning in both PSO and TM planes for estimating the depth of epidural space at the level of mid- and lower-thoracic spine is comparable.

Full Text Available BACKGROUND Intrathecal anaesthesia and epidural anaesthesia are the most popular regional anaesthesia techniques used for lower limb surgeries. Intrathecal anaesthesia also called as subarachnoid block. It has few limitations like short duration of anaesthesia, extension of anaesthesia cannot be made for prolonged surgeries, rapid onset of sympathetic blockade, shorter duration of postoperative analgesia and troublesome complication of Post-Dural Puncture Headache (PDPH. Hence, epidural anaesthesia is the most preferred anaesthetic technique for lower limb surgeries these days. METHODS TIME FRAME The study was conducted during period spanning December 2013 to November 2014. STUDY POPULATION Patients who met all inclusion criteria were randomly selected. No distinction is made between males and females. STUDY DESIGN A prospective, randomised, double blind, case control, observational, interventional comparative study is designed after getting the informed written consent was obtained from the patient. RANDOMISATION Randomisation was done using a computer generated random number table. One hundred patients scheduled for various elective lower limb surgical procedures belonging to ASA class I and II were included in the study. 1.

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

Purpose: The main objective of this survey is to describe the current practice of thoracic anesthesia in the Middle Eastern (ME) region. Methods: A prospective online survey. An invitation to participate was e-mailed to all members of the ME thoracic-anaesthesia group. A total of 58 members participated in the survey from 19 institutions in the Middle East. Questions concerned ventilation strategies during one-lung ventilation (OLV), anesthesia regimen, mode of postoperative analgesia, use of lung isolation techniques, and use of i.v. fluids. Results: Volume-controlled ventilation was favored over pressure-controlled ventilation (62% vs 38% of respondents, Panesthesia practice. Failure to pass a DLT and difficult airway are the most commonly cited indications for BB use. Regarding postoperative analgesia, the majority 61.8% favor thoracic epidural analgesia over other techniques (P<0.05). Conclusions: Our survey provides a contemporary snapshot of the ME thoracic anesthetic practice. PMID:23162388

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

Chest wall blunt trauma causes multiple rib fractures and will often be associated with significant pain and may compromise ventilator mechanics. Analgesia has great roll in rib fracture therapies, opioid are useful, but when used as sole agent may require such high dose that they produce respiratory depression, especially in elderly .the best analgesia for a severe chest wall injury is a continuous epidural infusion of local anesthetic. This provides complete analgesia allowing inspiration and coughing without of the risk of respiratory depression. sixty adult patients who with multiple rib fractures were enrolled in this study. They were divided into Group A or thoracic epidural with bupivacaine 0.125 % +1mg/5ml morphine and group B or intercostal block with 0.25% bupivacaine. The patients were assessed through ICU and hospital stay length, ventilation function tests. Pain score among the patients was measured with verbal rating scale, before and after administration of the analgesia. We found a significant improvement in ventilatory function tests during the 1st, 2nd, and 3rd days after epidural analgesia compared with the intercostal block (P pain at rest and pain caused by coughing and deep breathing in group A compared group B... ICU and hospital stay markedly reduced in Group A. thoracic epidural analgesia is superior to intercostals block regarding pain relief of rib fractures. Patients who received epidural analgesia had significantly lower pain scores at all studied times.

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.

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

Paraplegia following epidural analgesia: A potentially avoidable cause?

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 Introduction: Chest wall blunt trauma causes multiple rib fractures and will often be associated with significant pain and may compromise ventilator mechanics. Analgesia has great roll in rib fracture therapies, opioid are useful, but when used as sole agent may re-quire such high dose that they produce respiratory depression, especially in el-derly .the best analgesia for a severe chest wall injury is a continuous epidural infusion of local anesthetic. This provides complete analgesia allowing inspiration and coughing without of the risk of respiratory depression. Methods: sixty adult patients who with multiple rib fractures were enrolled in this study. They were divided into Group A or thoracic epidural with bupivacaine 0.125 % +1mg/5ml morphine and group B or inter-costal block with %0.25 bupivacaine. The patients were assessed through ICU and hos-pital stay length, ventilation function tests. Pain score among the patients was meas-ured with verbal rating scale, before and after administration of the analgesia. Results: We found a significant improvement in ventilatory function tests during the 1st, 2nd, and 3rd days after epidural analgesia compared with the intercostal block (P < 0.004. Changes in the visual Analogue Scale were associated with marked improvement re-garding pain at rest and pain caused by coughing and deep breathing in group A com-pared group B... ICU and hospital stay markedly reduced in Group A. Conclusion: tho-racic epidural analgesia is superior to intercostals block regarding pain relief of rib frac-tures. Patients who received epidural analgesia had significantly lower pain scores at all studied times.

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.

Thoracic epidural catheter placement is an example of a demanding and high-risk clinical skill that junior anaesthetists need to learn by experience and under the supervision of consultants. This learning is known to present challenges that require further study. Ten consultant and 10 trainee anaesthetists in a teaching hospital were interviewed about teaching and learning this skill in the operating theatre, and a phenomenological analysis of their experience was performed. Trainee participation was limited by time pressure, lack of familiarity with consultants, and consultants' own need for clinical experience. There was a particular tension between safe and effective consultant practice and permitting trainees' independence. Three distinct stages of participation and assistance were identified from reports of ideal practice: early (part-task or basic procedure, consultant always present giving instruction and feedback), middle (independent practice with straightforward cases without further instruction), and late (skill extension and transfer). Learning assistance provided by consultants varied, but it was often not matched to the trainees' stages of learning. Negotiation of participation and assistance was recognized as being useful, but it did not happen routinely. There are many obstacles to trainees' participation in thoracic epidural catheter insertion, and learning assistance is not matched to need. A more explicit understanding of stages of learning is required to benefit the learning of this and other advanced clinical skills.

Full Text Available Background: To compare the efficacy and safety of local anaesthetics under cervical epidural anaesthesia (CEA using lignocaine (1%, bupivacaine (0.25% and ropivacaine (0.5% for thyroid surgery. Methods: In a prospective, randomized fashion, 81 patients were selected for thyroid surgery under CEA. They were assigned to one of three groups: Group L, B and R to receive 10 mL of 1% lignocaine, 0.25% bupivacaine and 0.5% ropivacaine, respectively. We compared their efficacy in terms of pulmonary and haemodynamic parameters, blockade quality and complications. Results: Of the total, 74 patients completed the study successfully. Sensory block attained the median dermatomal range of C2-T4/T5 in all the groups. Motor block was more pronounced in the ropivacaine group. Cardiorespiratory parameters decreased significantly in all the groups; however, none of the patients had any major complications except for bradycardia in two patients. Among the measured variables, the decrease in heart rate and peak expiratory force was more in the lignocaine group while forced vital capacity and forced expiratory volume at 1 sec declined to a greater extent in the ropivacaine group. The lignocaine group required significantly more epidural top-ups compared with the other two groups. Conclusion: We conclude that cervical epidural route can be safely used for surgery on thyroid gland in patients with normal cardiorespiratory reserve, using either of local anaesthetics chosen for our study. Under the selected dose and concentrations, the decrease in cardiorespiratory parameters was lesser with bupivacaine.

Full Text Available Regional anaesthesia is becoming one of the most useful and versatile procedures in modern anesthesiology. Bupivacaine is a long acting amide local anaesthetic which is widely used since years, but it is associated with a many side effects like Central Nervous System (CNS toxicity and cardio toxicity. Ropivacaine is a newly introduced long acting amide local anaesthetic drug in India which has been developed as a possible alternative to Bupivacaine. It has a lower lipophilicity than bupivacaine and hence associated with a decreased potential f or CNS and cardiotoxicity. AIMS : The aim of the study was to compare the time of onset of sensory block and duration of sensory and motor blockade, duration of analgesia of epidural anaesthesia produced by bupivacaine 0.5% and ropivacaine 0.75% for lower a bdominal & limb surgery. METHODS : A prospective randomised study 60 patients, aged between 18 - 60 years, ASA 1 and 2, undergoing various lower abdominal & limb surgeries were randomly allocated to 2 groups of 30 each. Group B received 15ml of 0.5% bupivacai ne and group R received 15 ml of 0.75% bupivacaine epidurally. The time of onset of sensory, intensity of motor block, duration of sensory and motor block and hemodynamic changes were assessed. RESULTS : The time of onset and duration of sensory block was comparable for both the drugs. Bupivacaine 0.5% produced more intensity and longer duration of motor block than ropivacaine 0.75%. Both the drugs were comparable with respect to hemodynamic changes. CONC LUSION : Epidural ropivacaine 0.75% can be safely used as a possible alternative to bupivacaine 0.5% in lower abdominal and extremity procedures

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

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

Hemangiopericytoma is an uncommon mesenchymal neoplasm that rarely affects the spinal canal. Primary malignant hemangiopericytoma of the spinal column is extremely rare. We report on a case of primary epidural malignant hemangiopericytoma of the thoracic spinal column that invaded vertebral bone and caused spinal cord compression in a 21-year-old man. The patient presented with progressive back pain over a four-month period that progressed to paraparesis, bilateral leg paresthesia and urinary incontinence. The surgical intervention involved laminectomy and subtotal resection of the tumor, with posterior vertebral fixation. Postoperative involved-field radiotherapy was administered. A marked neurological improvement was subsequently observed. We describe the clinical, radiological, and histological features of this tumor and review the literature.

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

Full Text Available The purpose of the article is to establish adequacy of protection of energy metabolism in a patient under anaes-thesiology in cholecystectomy from mini-access. Material et methods: 122 patients subjected to cholecystectomy from mini access have been surveyed. Among them 92 patients have got intravenous general anaesthesia with AVL, 30 patients have got prolonged epidural anaesthesia on spontaneous breath with insufflations of oxygen through an obverse mask with sedatations. Monitoring of energy-plastic metabolism has been carried out in all patients. Results: Groups of patients have been compared by anthropometrical data, traumatic interventions. In both groups of patients loss of energy to traumatic to an operation stage has insignificantly increased, but after the anaesthesia termination in the group of patients with intravenous anaesthesia loss of energy continued to rise, and in the group of patients with prolonged epidural blockade it has returned to the initial level. After the anaesthesia termination the energy metabolism became essential higher in the first group of patients in comparison with the second one (p <0,01. The energy-plastic metabolism increased in the first group of patients and decreased in the second. PEA during cholecystectomy from mini access provided a stable condition of energy and energy-plastic metabolism. The conclusion: The inspection of 122 patients subjected to cholecystectomy from mini access has established the following data: PEA on spontaneous breath with insufflations of oxygen through an obverse mask in comparison with intravenous general anaesthesia and AVL allows keeping on an optimum level of energy and energy-plastic metabolism.

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

LENUS (Irish Health Repository)

Fanning, Rebecca A

2012-02-01

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

2016-01-01

Full Text Available We present a rare case of spinal epidural hematoma (SEH after thoracolumbar posterior fusion without decompression surgery for a thoracic vertebral fracture. A 42-year-old man was hospitalized for a thoracic vertebral fracture caused by being sandwiched against his back on broken concrete block. Computed tomography revealed a T12 dislocation fracture of AO type B2, multiple bilateral rib fractures, and a right hemopneumothorax. Four days after the injury, in order to promote early orthostasis and to improve respiratory status, we performed thoracolumbar posterior fusion surgery without decompression; the patient had back pain but no neurological deficits. Three hours after surgery, he complained of acute pain and severe weakness of his bilateral lower extremities; with allodynia below the level of his umbilicus, postoperative SEH was diagnosed. We performed immediate revision surgery. After removal of the hematoma, his symptoms improved gradually, and he was discharged ambulatory one month after revision surgery. Through experience of this case, we should strongly consider the possibility of preexisting SEH before surgery, even in patients with no neurological deficits. We should also consider perioperative coagulopathy in patients with multiple trauma, as in this case.

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.

Unusual case of persistent Horner′s syndrome following epidural anaesthesia and caesarean section

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.

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

The use of a test dose in epidural anaesthesia is a safety recommendation. However specificity and sensitivity of the drugs used with this indication have been not conclusive. The main objective of this study was to compare the effectiveness and the adverse effects of a simulated intravascular test dose of adrenaline, lidocaine and S(+)-ketamine. A prospective, randomized, double blinded, placebo controlled study was designed. ASA I patients scheduled for elective surgery were included. These were randomized to the following study groups: S(+)-ketamine 0.5 mg.kg-1 (S+K group), 5% lidocaine 1.5 mg.kg-1 (L5% group), adrenaline 15μg (ADR group), and physiological saline 3 ml (SF group; control group). An evaluation was made during the first 15 minutes after the study drug was administered. Variables including heart rate (HR) systolic and diastolic blood pressure (sBP and dBP), mean arterial pressure (MAP), and SpO2 were recorded at 0 min (baseline) and at 2, 5, 8, 10 and 15 minutes after drug injection. An increase of at least 20 beats per minute (bpm) in relation to the baseline measurement was considered a positive result, as was an increase sBP >15 mmHg. The clinical effects described as related to iv injection of the study drugs recorded were: sedation-hypnosis, dizziness, nystagmus, metallic taste perception, perioral or facial paresthesias, tinnitus, as well as any other effect the patients mentioned. Sensitivity and specificity were calculated as was the percent increase in the parameters in order to see if these were clinically useful. A total of 80 patients, 20 per group, were included. The sBP, dBP, and MAP were significantly raised at the 2, 5, 8 and 10 minutes measurements in the S(+)K group compared to the rest of the groups (Padrenaline at the scheduled doses showed low sensitivity and specificity as a simulated iv epidural test dose. S(+)-ketamine could be a feasible marker after accidental iv injection during epidural anaesthesia or analgesia

Full Text Available Purpose Spinal teratomas comprise a rare subset of spinal cord tumors, and here, we describe an even rarer childhood thoracic extradural-intracanalicular teratoma. The clinical presentation, management, and pathophysiology of these tumors are reviewed to promote recognition and guide treatment of these lesions. Methods We report the case of a 21-month-old boy who presented with marked spasticity, as well as failure to ambulate and meet motor milestones. Additionally, we provide a literature review of spinal teratomas, including their clinical presentation, work-up, pathophysiology, and underlying genetics. Results An MRI of the spine revealed a large dorsal epidural tumor extending from T3 to T10 with heterogeneous contrast enhancement and severe spinal cord compression. The tumor was resected revealing a cystic mass with tissue resembling hair, muscle, as well as cartilage; pathology confirmed the diagnosis of teratoma. Gross total resection was achieved, and the child eventually gained ambulatory function. Conclusions Given that spinal teratomas are rare entities that can present with significant neurologic compromise, they must remain on clinicians’ differentials. Unfortunately, the exact origin of these tumors remains inconclusive and requires further investigation.

Sympathetic activity of S-(+-ketamine low doses in the epidural space

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

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

Rehage, J; Kehler, W; Scholz, H

1994-01-01

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.

Neonates and infants have decreased metabolic capacity for amide local anesthetics and increased risk of local anesthetic toxicity compared to the general population. Chloroprocaine is an ester local anesthetic that has an extremely short plasma half-life in infants as well as adults. Existing reports support the safety and efficacy of continuous chloroprocaine epidural infusions in neonates and young infants during the intraoperative period. Despite this, continuous chloroprocaine epidural infusion may be an under-utilized method of postoperative analgesia for this patient population. In particular, it may improve pain control in neonates and infants with incisions stretching many dermatomes or those with hepatic impairment. We retrospectively reviewed our experience over 4 years with continuous chloroprocaine epidural infusions in neonates, infants, and children with a focus on the postoperative management of pain. Twenty-one pediatric patients received continuous 2-chloroprocaine epidural infusions for postoperative pain management from January 2010 to April 2014 for thoracic, abdominal, and limb procedures. The epidural infusion consisted of 1.5% chloroprocaine or 1.5% chloroprocaine with fentanyl. Tabulating the morphine and hydromorphone used for rescue analgesia, the median (interquartile range) opioid consumption (mg·kg(-1) ·day(-1) of intravenous morphine equivalents) for the first, second, and third 24-h postoperative periods were 0.02 (0-0.48), 0.30 (0-0.44), and 0.14 (0-0.29), respectively. Examining the total fentanyl usage, the median (interquartile range) fentanyl consumption (μg·kg(-1) ·day(-1)) for first, second, and third 24-h postoperative periods were 3.89 (0.41-7.24), 0 (0.00-4.06), and 0 (0.00-0.51), respectively. The median N-PASS score assessed every 6 h from 0 to 72 h postoperatively was 0, 1, 2, 0, 0, 1, 0, 0, 0, 0, 1, 0, and 0, respectively. The median FLACC score assessed every 6 h from 0 to 72 h postoperatively was 0, 0, 2, 0, 0, 0

NERVE BLOCKING (PAIN CONTROL AFTER THORACOTOMY WITH BUPIVACAINE:EPIDURAL VS INTERCOSTAL

2001-09-01

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.

Innovative Approaches to Neuraxial Blockade in Children: The Introduction of Epidural Nerve Root Stimulation and Ultrasound Guidance for Epidural Catheter Placement

Directory of Open Access Journals (Sweden)

Ban CH Tsui

2006-01-01

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.

Regional (spinal, epidural, caudal) versus general anaesthesia in preterm infants undergoing inguinal herniorrhaphy in early infancy.

2015-06-09

With improvements in neonatal intensive care, more preterm infants are surviving the neonatal period and presenting for surgery in early infancy. Inguinal hernia is the most common condition requiring early surgery, appearing in 38% of infants whose birth weight is between 751 grams and 1000 grams. Approximately 20% to 30% of otherwise healthy preterm infants having general anaesthesia for inguinal hernia surgery at a postmature age have at least one apnoeic episode within the postoperative period. Research studies have failed to adequately distinguish the effects of apnoeic episodes from other complications of extreme preterm gestation on the risk of brain injury, or to investigate the potential impact of postoperative apnoea upon longer term neurodevelopment. In addition to episodes of apnoea, there are concerns that anaesthetic and sedative agents may have a direct toxic effect on the developing brain of preterm infants even after reaching postmature age. It is proposed that regional anaesthesia may reduce the risk of postoperative apnoea, avoid the risk of anaesthetic-related neurotoxicity and improve neurodevelopmental outcomes in preterm infants requiring surgery for inguinal hernia at a postmature age. To determine if regional anaesthesia reduces postoperative apnoea, bradycardia, the use of assisted ventilation, and neurological impairment, in comparison to general anaesthesia, in preterm infants undergoing inguinal herniorrhaphy at a postmature age. The following databases and resources were searched: the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, 2015, Issue 2), MEDLINE (December 2002 to 25 February 2015), EMBASE (December 2002 to 25 February 2015), controlled-trials.com and clinicaltrials.gov, reference lists of published trials and abstracts published in Pediatric Research and Pediatric Anesthesia.

2015-11-01

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

Thoracic Cavernoma with Intraosseous and Extradural Component Mimicking Metastasis: Case Presentation

Directory of Open Access Journals (Sweden)

Kocaman Umit

2016-09-01

Full Text Available Spinal epidural cavernomas are quite rare lesions and only 5% of all cavernomas are located in the spine. The lesions are most commonly localized in the thoracic region. The differential diagnosis includes neurogenic tumors, lymphoma, schwannoma, meningioma, multiple myeloma, Ewing's sarcoma and metastasis. A 40- year-old male patient presented with paraplegia and MR images revealed an epidural soft tissue constricting the right posterolateral of the cord at the T6 level. Pathology showed cavernous hemangioma. A literature search revealed no other case that so closely mimicked metastasis by invading all components of the thoracic vertebra and also expanding to the epidural distance. We therefore present the case emphasizing these features.

Preterm delivery is often performed by Caesarean section. We investigated modes of anaesthesia and risk factors for general anaesthesia among women undergoing preterm Caesarean delivery. Women undergoing Caesarean delivery between 24(+0) and 36(+6) weeks' gestation were identified from a multicentre US registry. The mode of anaesthesia was classified as neuraxial anaesthesia (spinal, epidural, or combined spinal and epidural) or general anaesthesia. Logistic regression was used to identify patient characteristic, obstetric, and peripartum risk factors associated with general anaesthesia. Within the study cohort, 11 539 women had preterm Caesarean delivery; 9510 (82.4%) underwent neuraxial anaesthesia and 2029 (17.6%) general anaesthesia. In our multivariate model, African-American race [adjusted odds ratio (aOR)=1.9; 95% confidence interval (CI)=1.7-2.2], Hispanic ethnicity (aOR=1.5; 95% CI=1.2-1.8), other race (aOR=1.4; 95% CI=1.1-1.9), and haemolysis, elevated liver enzymes and low platelets (HELLP) syndrome or eclampsia (aOR=2.8; 95% CI=2.2-3.5) were independently associated with receiving general anaesthesia for preterm Caesarean delivery. Women with an emergency Caesarean delivery indication had the highest odds for general anaesthesia (aOR=3.5; 95% CI=3.1-3.9). For every 1 week decrease in gestational age at delivery, the adjusted odds of general anaesthesia increased by 13%. In our study cohort, nearly one in five women received general anaesthesia for preterm Caesarean delivery. Although potential confounding by unmeasured factors cannot be excluded, our findings suggest that early gestational age at delivery, emergent Caesarean delivery indications, hypertensive disease, and non-Caucasian race or ethnicity are associated with general anaesthesia for preterm Caesarean delivery. © The Author 2015.

Imaging of human vertebral surface using ultrasound RF data received at each element of probe for thoracic anesthesia

Takahashi, Kazuki; Taki, Hirofumi; Onishi, Eiko; Yamauchi, Masanori; Kanai, Hiroshi

2017-07-01

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.

Solitary Spinal Epidural Metastasis from Gastric Cancer

Directory of Open Access Journals (Sweden)

Taisei Sako

2016-01-01

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.

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

In modern obstetrics, different pharmacological and non-pharmacological options allow to obtain pain relief during labour, one of the most important goals in women satisfaction about medical care. The aim of this review is to compare all the analgesia administration schemes in terms of effectiveness in pain relief, length of labour, mode of delivery, side effects and neonatal outcomes. A systematic literature search was conducted in electronic databases in the interval time between January 1999 and March 2013. Key search terms included: “labour analgesia”, “epidural anaesthesia during labour” (excluding anaesthesia for Caesarean section), “epidural analgesia and labour outcome” and “intra-thecal analgesia”. 10,331 patients were analysed: 5,578 patients underwent Epidural-Analgesia, 259 patients spinal analgesia, 2,724 combined spinal epidural analgesia, 322 continuous epidural infusion (CEI), 168 intermittent epidural bolus, 684 patient-controlled infusion epidural analgesia and 152 intra-venous patient-controlled epidural analgesia. We also considered 341 women who underwent patient-controlled infusion epidural analgesia in association with CEI and 103 patients who underwent patient-controlled infusion epidural analgesia in association with automatic mandatory bolus. No significant differences occurred among all the available administration schemes of neuraxial analgesia. In absence of obstetrical contraindication, neuraxial analgesia has to be considered as the gold standard in obtaining maternal pain relief during labour. The options available in the administration of analgesia should be known and evaluated together by both gynaecologists and anaesthesiologists to choose the best personalized scheme and obtain the best women satisfaction. Since it is difficult to identify comparable circumstances during labour, it is complicate to standardize drugs schemes and their combinations.

Background: Post-dural puncture headache (PDPH) is a common problem in anaesthesia practice especially in obstetric anaesthesia. Autologous epidural blood patch (AEBP) is the main stay of treatment of PDPH when it is not relieved with conservative management. Objective: To describe the efficacy of AEBP in treatment of PDPH. Study Design: Prospective descriptive study. Setting and Duration: The study was conducted at departments of Anaesthesia and Intensive Care, Military Hospital, Rawalpindi and Combined Military Hospital, Malir, from July 2008 to July 2011. Methodology: All patients who received AEBP during study period secondary to PDPH were included. Up to 20 ml of autologous blood was injected in epidural space. Effectiveness of AEBP was judged by relief of symptom; any complications associated with AEBP i.e. backache and paresthesia were also noted. Data was interpreted as mean and percentages. Results: A total of 30 AEBP were performed during the study period in predominantly female patients (n=27) with mean age of 27.8 years. AEBP was performed after a mean 3.83 days of lumbar puncture. Complete relief was observed in 29 (96%) patients; one patient required a second patch. During the follow-up, 7 (23%) patients complained of backache and 2(6%) of paresthesias. conclusion: AEBP is an effective way of providing relief from PDPH. (author)

[Interest of ultrasonographic guidance in paediatric regional anaesthesia].

Dadure, C; Raux, O; Rochette, A; Capdevila, X

The use of ultrasonographic guidance for regional anaesthesia has known recently a big interest in children in recent years. The linear ultrasound probes with a 25 mm active surface area (or probes with 38 mm active surface area in older children), with high sound frequencies in the range 8-14 MHz, allow a good compromise between excellent resolution for superficial structure and good penetration depths. In children, the easiest ultrasound guided blocks are axillar blocks, femoral blocks, fascia iliaca compartment blocks, ilio-inguinal blocks and para-umbilical blocks, caudal blocks. They permit a safe and easy learning curve of these techniques. The main advantage of ultrasound guided regional anaesthesia is the visualization of different anatomical structures and the approximate localization of the tip of needle. The other advantages for ultrasound guided peripheral nerve blocks in children are: faster onset time of sensory and motor block, longer duration of sensory blockade, increase of blockade quality and reduction of local anesthetic injection. The use of ultrasonographic guidance for central block allows to visualize different structures as well as spine and his content. Spinous process, ligament flavum, dura mater, conus medullaris and cerebrospinal fluid are identifiable, and give some information on spine, epidural space and the depth between epidural space and skin. At last, in caudal block, ultrasounds permit to evaluate the anatomy of caudal epidural space, especially the relation of the sacral hiatus to the dural sac and the search of occult spinal dysraphism. Benefit of this technique is the visualization of targeted nerves or spaces and the spread of injected local anaesthetic.

Full Text Available This study demonstrates effective thoracic epidural analgesia by ropivacain 0.2 %, phentanyl 2 mkg/ml, adrenaline 2 mkg/ml in single-use infusion pumps in 124 patients, who underwent surgery for colorectal cancer. Safe, effective and controllable analgesia was observed during surgery and postoperative period. Prolonged analgesia facilitates early rehabilitation and improves gastrointestinal peristaltic activity.  Prolonged epidural analgesia is the recommended method of analgesia in this group of patients.

Spinal cord injury arising in anaesthesia practice.

Spinal cord injury arising during anaesthetic practice is a rare event, but one that carries a significant burden in terms of morbidity and mortality. In this article, we will review the pathophysiology of spinal cord injury. We will then discuss injuries relating to patient position, spinal cord hypoperfusion and neuraxial techniques. The most serious causes of spinal cord injury - vertebral canal haematoma, spinal epidural abscess, meningitis and adhesive arachnoiditis - will be discussed in turn. For each condition, we draw attention to practical, evidence-based measures clinicians can undertake to reduce their incidence, or mitigate their severity. Finally, we will discuss transient neurological symptoms. Some cases of spinal cord injury during anaesthesia can be ascribed to anaesthesia itself, arising as a direct consequence of its conduct. The injury to a spinal nerve root by inaccurate and/or incautious needling during spinal anaesthesia is an obvious example. But in many cases, spinal cord injury during anaesthesia is not caused by, related to, or even associated with, the conduct of the anaesthetic. Surgical factors, whether direct (e.g. spinal nerve root damage due to incorrect pedicle screw placement) or indirect (e.g. cord ischaemia following aortic surgery) are responsible for a significant proportion of spinal cord injuries that occur concurrently with the delivery of regional or general anaesthesia. © 2018 The Association of Anaesthetists of Great Britain and Ireland.

Full Text Available The cardiovascular effects of non-abdominal and abdominal surgery during isoflurane anaesthesia (A-group or isoflurane anaesthesia supplemented with either epidural ropivacaine (AR-group; 0.75 % solution, 0.2 mℓ/kg or morphine (AM-group; 0.1 mg/kg diluted in saline to 0.2mℓ/kg were evaluated in 28 healthy pigs with a mean body weight of 30.3 kg SD ± 4.1 during surgical devascularisation of the liver. Anaesthesia was induced with the intramuscular injection of midazolam (0.3 mg/kg and ketamine (10 mg/kg. Anaesthesia was deepened with intravenous propofol to enable tracheal intubation and maintained with isoflurane on a circle rebreathing circuit. The vaporiser was set at 2.5% for the A-group and 1.5% for the AR- and AM-groups. Differences between treatment groups were not statistically significant (P>0.05 for any of the variables. Differences between AM- and AR-groups were marginally significant heart rate (HR (P = 0.06 and mean arterial blood pressure (MAP (P = 0.08. Within treatment groups, differences for the A-group were statistically significant (P 0.05. It was concluded that in isoflurane-anaesthetised pigs, the epidural administration of ropivacaine decreased heart rate and improved arterial blood pressure during surgery.

To reduce the incidence of urinary tract infection, Surgical Care Improvement Project 9 mandates the removal of urinary catheters within 48 hours postoperatively. In patients with thoracic epidural anesthesia, we sought to determine the rate of catheter reinsertion, the complications of reinsertion, and the factors associated with reinsertion. We conducted a prospective observational study of consecutive patients undergoing major pulmonary or esophageal resection with thoracic epidural analgesia over a 2-year period. As per Surgical Care Improvement Project 9, all urinary catheters were removed within 48 hours postoperatively. Excluded were patients with chronic indwelling catheter, patients with urostomy, and patients requiring continued strict urine output monitoring. Multivariable logistic regression analysis was used to identify independent risk factors for urinary catheter reinsertion. Thirteen patients met exclusion criteria. Of the 275 patients evaluated, 60 (21.8%) required reinsertion of urinary catheter. There was no difference in the urinary tract infection rate between patients requiring reinsertion (1/60 [1.7%]) versus patients not requiring reinsertion (1/215 [0.5%], P = .389). Urethral trauma during reinsertion was seen in 1 of 60 patients (1.7%). After reinsertion, discharge with urinary catheter was required in 4 of 60 patients (6.7%). Multivariable logistic regression analysis found esophagectomy, lower body mass index, and benign prostatic hypertrophy to be independent risk factors associated with catheter reinsertion after early removal in the presence of thoracic epidural analgesia. When applying Surgical Care Improvement Project 9 to patients undergoing thoracic procedures with thoracic epidural analgesia, consideration to delayed removal of urinary catheter may be warranted in patients with multiple risk factors for reinsertion.

An increased number of errors and reduced patient safety have been reported during the incorporation of residents, as this period involves learning new skills. The objectives were to evaluate the learning outcomes of an immersive simulation boot-camp for incoming residents before starting the clinical rotations. Airway assessment, airway control with direct laryngoscopy, and epidural catheterization competencies were evaluated. Twelve first-year anaesthesiology residents participated. A prospective study to evaluate transfer of endotracheal intubation skills learned at the simulation centre to clinical practice (primary outcome) was conducted. A checklist of 28 skills and behaviours was used to assess the first supervised intubation performed during anaesthesia induction in ASA I/II patients. Secondary outcome was self-efficacy to perform epidural catheterization. A satisfaction survey was also performed. Seventy-five percent of residents completed more than 21 out of 28 skills and behaviours to assess and control the airway during their first intubation in patients. Twelve items were performed by all residents and 5 by half of them. More than 83% of participants reported a high level of self-efficacy in placing an epidural catheter. All participants would recommend the course to their colleagues. A focused intensive simulation-based boot-camp addressing key competencies required to begin anaesthesia residency was well received, and led to transfer of airway management skills learned to clinical settings when performing for first time on patients, and to increased self-reported efficacy in performing epidural catheterization.

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

Analgesia and anaesthesia in childbirth: obscurantism and obfuscation.

Science.gov (United States)

Mander, R

1998-07-01

The terms 'analgesia' and 'anaesthesia' have been defined by emphasizing differing aspects of their effects. The distinction between these interventions has not been clarified by their definitions. The historical remedies for pain were similarly unclear. This lack of clarity is apparent in the introduction of chloroform in childbirth, which has much in common with the introduction and effects of epidural analgesia. The reasons for and benefits of this lack of clarity are examined.

[Modification of the analgetic effects (buprenorphine, pentazocine, pethidine) on respiration and haemodynamics by epidural, halothane- or neuroleptanaesthesia (author's transl)].

In 38 patients buprenorphine, meperidine and pentazocine were given in a single dose for postoperative pain relief 20 hours after the end of anaesthesia. Measuring the parameters of the high- and low-pressure system as well as the metabolism the authors found that the effects of these analgetic medicaments, intravenously injected were significantly influenced by fentanyl, halothane or diazepam, given under the course of operation. Especially buprenorphine, injected after epidural anaesthesia in combination with diazepam sedation, proved to have a rather negative effect, because it caused a strong depression of respiration and circulation. On the other hand buprenorphine had, given after neuroleptanaesthesia, a neutralizing - and pentazocine and pethidine in combination with neuroleptanaesthesia a stimulating influence on the circulation. After halothane-anaesthesia the effect of the analegtics on the cardiovascular system was, when buprenorphine was given, depressing and when pentazocine was given indifferent. Similar reactions, but more pronounced, could be seen in the epidural group. With certain reservations, caused by the preliminary character of this study, the following conclusions can be drawn for the anaesthetic practice: 1 Choosing analgetic drugs for postoperative pain relief, the anaesthesist has to be aware of the interactions, possibly resulting from the medicaments, given during anaesthesia. 2. The number of medicaments, given during anaesthesia, should be kept small, considering the eventual interactions and the unintentional secondary effects.

To compare the effect of a single epidural injection of either lignocaine or tramadol on behavioural changes, anaesthetic indices, leucocyte parameters, erythrocyte sedimentation rates and concentration of cortisol in plasma in goats subjected to castration by high tension band. Ten male goats weighing 14.4 (SD 0.7) kg were randomly allocated to anaesthesia with epidural injections of tramadol (3 mg/kg), or lignocaine (4 mg/kg). Following anaesthesia, a rubber ring was applied and tensioned to the scrotal neck of each goat. Behavioural changes were noted as they occurred, and the onset of drug action (time between epidural injection and loss of pedal reflex) and duration of antinociception (time interval between disappearance and reappearance of pedal withdrawal reflex) were determined. Hearts rates, respiratory rates and rectal temperatures were determined every 15 minutes for a 90-minute period, while blood was obtained for determination of white cell counts, erythrocyte sedimentation rates and concentrations of cortisol. Anaesthetic indices were compared using Student's t-test, while physiological parameters were compared using an ANOVA for repeated measurements. Goats treated with epidural tramadol were not recumbent and continued rumination while goats treated with epidural lignocaine were recumbent and did not continue rumination. The onset of analgesia was longer (p=0.01) in goats treated with epidural tramadol (5.0 minutes; SD 1.2) than goats treated with epidural lignocaine (3.0 minutes; SD 1.1), while duration of analgesia was shorter (p=0.003) in goats treated with epidural tramadol (47.2 minutes; SD 13.1) than goats treated with epidural lignocaine (89.8 minutes; SD 23.1). There was no significant difference in heart rates, respiratory rates and erythrocyte sedimentation rates, while the concentration of cortisol in plasma differed (pcattle and where the ability of the animal to maintain standing is desired.

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

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

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.

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

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

To explore the relationship of motor deficits of the lower extremities with the imaging features of malignant spinal cord compression (MESCCs). From July 2006 through December 2008, 56 successive MESCC patients were treated at our department. All were evaluated by magnetic resonance imaging and computed tomography and were scored according to motor deficits Frankel grading on admission. Imaging assessment factors of main involved vertebrae were level of vertebral metastatic location, epidural space involvement, vertebral body involvement, lamina involvement, posterior protrusion of posterior wall, pedicle involvement, continuity of main involved vertebrae, fracture of anterior column, fracture of posterior wall, location in upper thoracic spine and/or cervicothoracic junction. Occurrence was the same between paralytic state of MESCCs and epidural space involvement of imaging features. Multiple regression equation showed that paralytic state had a linear regression relationship with imaging factors of lamina involvement (X1), posterior protrusion of posterior wall (X2), location in upper thoracic spine and/or cervicothoracic junction (X7) of main involved vertebrae. The optimal regression equation of paralytic state (Y) and imaging feature (X) was Y = -0.009 +0.639X, + 0.149X, +0.282X. Lamina involvement of main involved vertebrae has a greatest influence upon paralytic state of MESCC patients. Imaging factors of lamina involvement, posterior protrusion of posterior wall, location in upper thoracic spine and/or cervicothoracic junction of main involved vertebrae can predict the paralytic state of MESCC patients. MESCC with lamina involvement is more easily encroached on epidural space.

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

Thoracic disc herniation is a relatively rare yet challenging-to-diagnose condition. Currently there is no universally accepted optimal surgical treatment for symptomatic thoracic disc herniation. Previously reported surgical approaches are often associated with high complication rates. Here we describe our minimally invasive technique of removing thoracic disc herniation, and report the primary results of a series of cases. Between January 2009 and March 2012, 13 patients with symptomatic thoracic disc herniation were treated with endoscopic thoracic foraminotomy and discectomy under local anesthesia. A bone shaver was used to undercut the facet and rib head for foraminotomy. Discectomy was achieved by using grasper, radiofrequency, and the Holmium-YAG laser. We analyzed the clinical outcomes of the patients using the visual analogue scale (VAS), MacNab classification, and Oswestry disability index (ODI). At the final follow up (mean: 17 months; range: 6–41 months), patient self-reported satisfactory rate was 76.9%. The mean VAS for mid back pain was improved from 9.1 to 4.2, and the mean ODI was improved from 61.0 to 43.8. One complication of postoperative spinal headache occurred during the surgery and the patient was successfully treated with epidural blood patch. No other complications were observed or reported during and after the surgery. PMID:24455232

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

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.

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 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.

Postoperative Paraplegia as a Result of Undiagnosed Primitive Neuroectodermal Tumor, Not Epidural Analgesia

Directory of Open Access Journals (Sweden)

Pei-Ching Hung

2007-10-01

Full Text Available Postoperative paraplegia is a rare complication after epidural analgesia and often occurs with spinal hematoma or cord injury. We present the case of a 16-year-old girl who suffered from a tumor mass in the neck and abdomen who underwent gynecologic operation. Preoperatively, liver metastasis was found by computed tomography. Pathologic findings revealed that the abdominal mass was an ovarian dermoid cyst. After the operation, the patient complained of paraplegia while receiving epidural analgesia for postoperative pain control. A peripheral primitive neuroectodermal tumor in the thoracic and lumbar spines with spinal cord compression was later detected using magnetic resonance imaging. Learning from this case, we suggest that when a patient is preoperatively diagnosed with tumor metastasis, back pain and soreness, spinal cord compression from tumor metastasis should be excluded before epidural analgesia is implemented.

Full Text Available Cor Slagt Radboud University Medical Center, Department Anaesthesia, Pain and Palliative Medicine, Nijmegen, the NetherlandsAfter reading the article, “Thoracic combined spinal epidural anesthesia for laparoscopic cholecystectomy in a geriatric patient with ischemic heart disease and renal insufficiency” by Mehta et al,1 I have the following considerations. Laparoscopic cholecystectomy was performed under spinal anesthesia in healthy patients.2 Perioperative hemodynamic instability (59% and discomfort (43% were noticed in this group of 49 patients. From the gastroenterology literature, we know that a combination of lumbar spinal and thoracic epidural anesthesia can be used as a monotherapy for high-risk patients undergoing gastrointestinal and colorectal surgery.3 Perioperative hemodynamics and discomfort were not observed in 12 patients. Is this a stress-free environment? Preventing general anesthesia should not be a goal on its own. From an oxygen delivery-consumption point of view, general anesthesia reduces oxygen consumption and can promote oxygen delivery, theoretically preventing organ failure, especially in high-risk surgical patients with diseases that involve multiple organs.4 Our body has protected the delicate spinal cord by the vertebral column. Damaging the spinal cord during anesthesia, for instance, during epidural procedures, is one of the greatest fears of our patients and anesthesiologists.5,6 New techniques should be thoroughly tested on healthy patients before they are used on high-risk surgical patients. A combined thoracic spinal epidural anesthesia is, in the light of the above, an undesirable technique, especially combined with pneumoperitoneum when hemodynamic and respiratory homeostasis and patient comfort can be compromised. Although there is the possibility to place a thoracic combined spinal epidural anesthesia, I strongly like to emphasize that especially in the view of patient safety, this procedure is

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

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 We present a 32-year-old G1P0 woman at 32 weeks and two days gestation with new onset paraplegia, hyperreflexia, and sensory disturbance that gradually progressed over the past month and acutely worsened over the last 24 hours. MRI revealed a demyelinating process of the thoracic spine and diffuse cervicothoracic cord oedema. After 7 days, her foetus developed recurrent heart rate decelerations and an emergent caesarean section was performed. On airway exam, she was Mallampati 3 with a short thyromental distance. She reported fasting overnight and into the morning. Our choice was between performing neuraxial anaesthesia in the setting of an acute demyelinating process of her spinal cord versus general anaesthesia on a patient at risk of aspiration with a potentially difficult airway. Given the potential complications of neuraxial anaesthesia, we utilized rocuronium to perform a rapid sequence induction of general anaesthesia with endotracheal intubation.

Full Text Available Todd Britt, Ryan Sturm, Rick Ricardi, Virginia Labond Department of Emergency Medicine, Genesys Regional Medical Center, Grand Blanc, MI, USA Background: Thoracic trauma accounts for 10%–15% of all trauma admissions. Rib fractures are the most common injury following blunt thoracic trauma. Epidural analgesia improves patient outcomes but is not without problems. The use of continuous intercostal nerve blockade (CINB may offer superior pain control with fewer side effects. This study's objective was to compare the rate of pulmonary complications when traumatic rib fractures were treated with CINB vs epidurals. Methods: A hospital trauma registry provided retrospective data from 2008 to 2013 for patients with 2 or more traumatic rib fractures. All subjects were admitted and were treated with either an epidural or a subcutaneously placed catheter for continuous intercostal nerve blockade. Our primary outcome was a composite of either pneumonia or respiratory failure. Secondary outcomes included total hospital days, total ICU days, and days on the ventilator. Results: 12.5% (N=8 of the CINB group developed pneumonia or had respiratory failure compared to 16.3% (N=7 in the epidural group. No statistical difference (P=0.58 in the incidence of pneumonia or vent dependent respiratory failure was observed. There was a significant reduction (P=0.05 in hospital days from 9.72 (SD 9.98 in the epidural compared to 6.98 (SD 4.67 in the CINB group. The rest of our secondary outcomes showed no significant difference. Conclusion: This study did not show a difference in the rate of pneumonia or ventilator-dependent respiratory failure in the CINB vs epidural groups. It was not sufficiently powered. Our data supports a reduction in hospital days when CINB is used vs epidural. CINB may have advantages over epidurals such as fewer complications, fewer contraindications, and a shorter time to placement. Further studies are needed to confirm these statements

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.

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

Lai, Yi-Chen; Chia, Yuan-Yi; Lien, Wei-Hung

2017-03-01

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.

Full Text Available Introduction: Acute lymphoblastic leukemia is the most common malignancy in childhood. Main characteristics of the disease are fast proliferation of lymphoblastic cells in bone marrow, destruction of other cells, causing insufficiency in the bone marow and infiltration of the liver, spleen and the lymphatic nodes. Pulmonary abscess and necrotizing pneumonia are rarely found in pediatric population and usually represent a significant problem for treatment. These conditions often require some surgical treatment modalities. The main goal of anesthesiological approach is to provide good and safe perioperative conditions and adequate analgesia. Case report: During treatment of acute leukemia in a 15-year-old boy, complication inform absenting pneumonia left side lung was developed. After four months antibiotic and antifungal therapy wide broad,(nije jasno decision of consilium was to perform left inferior lobectomy. Antibiotic prophylaxis with Ceftazidime 50 mg/kg BM. We performed a combination of general anesthesia and thoracic epidural anesthesia. Intubation with Robertshaw double lume tube. Ultrasound guided central venous catheter in left jugular veine and arterial line in right radial arteria. Anesthesia depth was controlled with entropy method. Epidural catheter was intoduded on level Thl0-Th 11. Conclusion: One ventilation with double lumen tube prevents spillage of infection sputum into the healthy lung. Epidural analgesia in this clinical situation held numerous benefits especially as a way to reduce postoperative respiratory complications caused by acute pain.

utiliza a menudo para procedimientos estéticos de la mama y existen pocos relatos de su uso en mastectomías con exploración axilar. El presente estudio comparó la técnica con anestesia general en operaciones oncológicas de la mama. MÉTODO: Cuarenta pacientes que se dividieron en dos grupos. En el grupo epidural (n = 20 se hizo una epidural torácica con bupivacaína y fentanil asociados a la sedación con midazolam. El otro grupo (n = 20, recibió anestesia general convencional con propofol, atracurio y fentanil y mantenimiento con O2 e isoflurano. En el intraoperatorio y durante la operación, se verificó la necesidad de complementación de la anestesia o de la sedación y variables hemodinámicas. En el postoperatorio fue registrado el tiempo para el alta de la sala de recuperación postanestésica y hospitalaria, la intensidad del dolor y el consumo de analgésicos, efectos adversos y la satisfacción con la técnica anestésica. RESULTADOS: Los grupos fueron similares y no hubo diferencia en la duración de la operación. Se hizo necesario complementar la sedación en un 100% de las pacientes que recibieron anestesia epidural y en un 15% fue complementada la analgesia con infiltración de anestésico local en la axila. Hubo una mayor incidencia de hipertensión arterial en el grupo de la anestesia general y de hipotensión entre las que recibieron epidural. Ocurrió prurito en un 55% de las pacientes con anestesia epidural. Náusea (30% y vómito (45%, fueron más frecuentes entre las que recibieron anestesia general. La analgesia postoperatoria tuvo una mejor calidad y el consumo de analgésicos fue menor en el grupo de la anestesia epidural. El período de internación también fue menor. CONCLUSIONES: La técnica epidural tiene algunas ventajas con relación a la anestesia general y puede ser considerada una opción para la anestesia en mastectomías oncológicas con vaciado axilar.BACKGROUND AND OBJECTIVES: Thoracic epidural block is frequently used for

Full Text Available Background: Caudal block with levobupivacaine or ropivacaine is the most commonly used regional anaesthesia in children. Methods: The aim of study was to compare the cardiocirculatory profile induced in two matched groups of young patients, submitted to caudal anaesthesia with levobupivacaine or ropivacaine for an elective subumbilical surgery. Sixty children were enrolled: thirty received levopubivacaine 0.25% and thirty ropivacaine 0.2%. Intraoperative heart rate (HR, systolic blood pressure (SBP, diastolic blood pressure (DBP were monitored at following times: Ta0 (after anaesthesia induction, Ta1 (after caudal anaesthesia, Ta2 (five minutes later, Ta3 (ten minutes later, Ts1 (at surgical incision, Ts2, Ts3, Ts4, Ts5 (every 10 minutes during surgery, Taw (at the awakening. Results: In both groups the cardiocirculatory trend remained within normal ranges at all times considered, demonstrating the safety of the method with both drugs. Both groups showed a similar trend at the different monitoring times: low decrease in HR, SBP and DBP after caudal block, slight increase in parameters after skin incision, slight decrease during surgery, increase at awakening. Regarding SBP and DBP, the levobupivacaine group children generally showed higher levels compared to the ropivacaine group, especially for DBP. Conclusions: Paediatric caudal anaesthesia is an effective method with an very infrequent complication rate. Possible hypotheses for differing haemodynamic behaviour could include a stronger vasoconstriction reflex of innervated areas during caudal anaesthesia with levobupivacaine and a lower levobupivacaine induced block of the sympathetic fibers, related to different pharmacokinetic profile of low concentrations of the local anaesthetics used in paediatric epidural space.

Continuous spinal anaesthesia with minimally invasive haemodynamic monitoring for surgical hip repair in two patients with severe aortic stenosis

2016-02-01

Full Text Available BACKGROUND AND OBJECTIVES: Aortic stenosis increases perioperative morbidity and mortality, perioperative invasive monitoring is advised for patients with an aortic valve area 30 mm Hg and it is important to avoid hypotension and arrhythmias. We report the anaesthetic management with continuous spinal anaesthesia and minimally invasive haemodynamic monitoring of two patients with severe aortic stenosis undergoing surgical hip repair. CASE REPORT: Two women with severe aortic stenosis were scheduled for hip fracture repair. Continuous spinal anaesthesia with minimally invasive haemodynamic monitoring was used for anaesthetic management of both. Surgery was performed successfully after two consecutive doses of 2 mg of isobaric bupivacaine 0.5% in one of them and four consecutive doses in the other. Haemodynamic conditions remained stable throughout the intervention. Vital signs and haemodynamic parameters remained stable throughout the two interventions. CONCLUSION: Our report illustrates the use of continuous spinal anaesthesia with minimally invasive haemodynamic monitoring as a valid alternative to general or epidural anaesthesia in two patients with severe aortic stenosis who are undergoing lower limb surgery. However, controlled clinical trials would be required to establish that this technique is safe and effective in these type or patients.

Thoracic trauma accounts for 10%-15% of all trauma admissions. Rib fractures are the most common injury following blunt thoracic trauma. Epidural analgesia improves patient outcomes but is not without problems. The use of continuous intercostal nerve blockade (CINB) may offer superior pain control with fewer side effects. This study's objective was to compare the rate of pulmonary complications when traumatic rib fractures were treated with CINB vs epidurals. A hospital trauma registry provided retrospective data from 2008 to 2013 for patients with 2 or more traumatic rib fractures. All subjects were admitted and were treated with either an epidural or a subcutaneously placed catheter for continuous intercostal nerve blockade. Our primary outcome was a composite of either pneumonia or respiratory failure. Secondary outcomes included total hospital days, total ICU days, and days on the ventilator. 12.5% (N=8) of the CINB group developed pneumonia or had respiratory failure compared to 16.3% (N=7) in the epidural group. No statistical difference (P=0.58) in the incidence of pneumonia or vent dependent respiratory failure was observed. There was a significant reduction (P=0.05) in hospital days from 9.72 (SD 9.98) in the epidural compared to 6.98 (SD 4.67) in the CINB group. The rest of our secondary outcomes showed no significant difference. This study did not show a difference in the rate of pneumonia or ventilator-dependent respiratory failure in the CINB vs epidural groups. It was not sufficiently powered. Our data supports a reduction in hospital days when CINB is used vs epidural. CINB may have advantages over epidurals such as fewer complications, fewer contraindications, and a shorter time to placement. Further studies are needed to confirm these statements.

The Child with Cerebral Palsy and Anaesthesia

Full Text Available Cerebral palsy (CP is the result of an injury to the developing brain during the antenatal, perinatal or postnatal period. Clinical manifestation relate to the areas affected. Patients with CP often present for elective surgical proce-dures to correct various deformities. Anaesthetic concerns of anaesthesia are intraoperative hypothermia , and slow emergence. Suxamethonium does not cause hyperkalaemia in these patients, and a rapid sequence induction may be indicated. Temperature should be monitored and an effort made to keep the patient warm. Cerebral abnormalities may lead to slow awakening; the patient should remain intubated until fully awake and airway reflexes have returned. Pulmonary infection can complicate the postoperative course. Postoperative pain management and the prevention of muscle spasms are important and drugs as baclofen and botulinum toxin are discussed. Epidural analgesia is particu-larly valuable when major orthopaedic procedures are performed.

Subcostal transversus abdominis plane (TAP) catheters have been reported to be an effective method of providing analgesia after upper abdominal surgery. We compared their analgesic efficacy with that of epidural analgesia after major upper abdominal surgery in a randomised controlled trial. Adult patients undergoing elective open hepatobiliary or renal surgery were randomly allocated to receive subcostal TAP catheters (n=29) or epidural analgesia (n=33), in addition to a standard postoperative analgesic regimen comprising of regular paracetamol and tramadol as required. The TAP group patients received bilateral subcostal TAP catheters and 1 mg.kg(-1) bupivacaine 0.375% bilaterally every 8 h. The epidural group patients received an infusion of bupivacaine 0.125% with fentanyl 2 μg.ml(-1) . The primary outcome measure was visual analogue pain scores during coughing at 8, 24, 48 and 72 h after surgery. We found no significant differences in median (IQR [range]) visual analogue scores during coughing at 8 h between the TAP group (4.0 (2.3-6.0 [0-7.5])) and epidural group (4.0 (2.5-5.3) [0-8.5])) and at 72 h (2.0 (0.8-4.0 [0-5]) and 2.5 (1.0-5.0 [0-6]), respectively). Tramadol consumption was significantly greater in the TAP group (p=0.002). Subcostal TAP catheter boluses may be an effective alternative to epidural infusions for providing postoperative analgesia after upper abdominal surgery. © 2011 The Authors.

Berdai, S; Benhamou, D

2004-10-01

Tomaculous neuropathy (or hereditary neuropathy with liability to pressure palsy [HNLPP]) is a rare and hereditary disease which incidence has probably been underestimated. It is characterised by demyelination resulting in numbness and weakness after nerve pressure, injury or stretch. Despite a well-documented genetic pathophysiologic mechanism, implications for anaesthesia in patients with HNLPP are only speculative and the use of regional anaesthesia is debatable. We report here the case of a patient with HNLPP who was followed during two consecutive pregnancies in the same hospital and for whom an expert of the SOS-RA hotline service was consulted before each delivery. For the first delivery, epidural analgesia was performed for labour pain control but a caesarean section was necessary because of failure to progress (0.0625% bupivacaine with 0.2 microg/ml sufentanil for labour then 2% lidocaine with adrenaline for surgery). Two years later, the patient was again seen for a preanaesthetic visit because elective Caesarean section was planned. Spinal anaesthesia using hyperbaric bupivacaine and sufentanil was used. Both deliveries were uneventful and there were no neurologic complaints in the postpartum periods.

Thoracic combined spinal epidural anesthesia for laparoscopic cholecystectomy in a geriatric patient with ischemic heart disease and renal insufficiency

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.

Aye, Christina Yi Ling; McKean, David; Dark, Allan; Akinsola, S Adeyemi

2012-01-01

A 36-year-old, healthy, primiparous female underwent a caesarean section under general anaesthetic. She had previously had a severe reaction to dye during a myelogram and therefore, had declined epidural analgesia or regional anaesthesia. Induction and maintenance of anaesthesia was uneventful, but on emergence, and before tracheal extubation, the patient coughed on the endotracheal tube and almost immediately developed right-sided subcutaneous emphysema of the face and neck. At this point her oxygen saturation began to fall and she was noted to be difficult to ventilate. Clinically and radiologically, she had a right-sided pneumothorax which was treated immediately with intercostal drain insertion. She went on to develop a left pneumothorax which also required intercostal drain insertion. She made an uneventful recovery and was discharged 8 days later. A subsequent CT scan of her chest revealed no pre-existing primary pulmonary pathology that would have accounted for the pneumothoraces. PMID:22927264

1988-01-01

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

Symptomatic Spinal Epidural Lipomatosis After a Single Local Epidural Steroid Injection

Tok, Chung Hong; Kaur, Shaleen; Gangi, Afshin

2011-01-01

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.

Pneumothorax in severe thoracic traumas

Camassa, N.W.; Boccuzzi, F.; Diettorre, E.; Troilo, A.

1988-01-01

The authors reviewed CT scans and supine chest X-ray of 47 patients affected by severe thoracic trauma, examined in 1985-86. The sensibility of the two methodologies in the assessment of pneumothorax was compared. CT detected 25 pneumothorax, whereas supine chest X-ray allowed a diagnosis in 18 cases only. In 8 of the latter (44.4%) the diagnosis was made possible by the presence of indirect signs of pneumothorax only - the most frequent being the deep sulcus sign. The characterization of pneumothorax is important especially in the patients who need to be treated with mechanical ventilation therapy, or who are to undergo surgery in total anaesthesia

Vinay, S; Khan, S K; Braybrooke, J R

2011-01-01

Vertebral haemangiomas are recognized to be one of the commonest benign tumours of the vertebral column, occurring mostly in the thoracic spine. The vast majority of these are asymptomatic. Infrequently, these can turn symptomatic and cause neurological deficit (cord compression) through any of four reported mechanisms: (1) epidural extension; (2) expansion of the involved vertebra(e) causing spinal canal stenosis; (3) spontaneous epidural haemorrhage; (4) pathological burst fracture. Thoracic haemangiomas have been reported to be more likely to produce cord compression than lumbar haemangiomas. A forty-nine year old male with acute onset spinal cord compression from a pathological fracture in a first lumbar vertebral haemangioma. An MRI delineated the haemangioma and extent of bleeding that caused the cord compression. These were confirmed during surgery and the haematoma was evacuated. The spine was instrumented from T12 to L2, and a cement vertebroplasty was performed intra-operatively. Written consent for publication was obtained from the patient. The junctional location of the first lumbar vertebra, and the structural weakness from normal bone being replaced by the haemangioma, probably caused it to fracture under axial loading. This pathological fracture caused bleeding from the vascularized bone, resulting in cord compression.

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.

Guay, Joanne; Sales, Karl

2015-08-27

Local anaesthesia for cataract surgery can be provided by sub-Tenon's or topical anaesthesia. Both techniques offer possible advantages. This review, which originally was published in 2007 and was updated in 2014, was undertaken to compare these two anaesthetic techniques. Our objectives were to compare the effectiveness of topical anaesthesia (with or without intracameral local anaesthetic) versus sub-Tenon's anaesthesia in providing pain relief during cataract surgery. We reviewed pain during administration of anaesthesia, postoperative pain, surgical satisfaction with operating conditions and patient satisfaction with pain relief provided, and we looked at associated complications. We searched the Cochrane Central Register of Controlled Trials, MEDLINE and EMBASE (last search in November 2014) and the reference lists of published articles. We looked for conferences abstracts and trials in progress and placed no constraints on language or publication status. We included all randomized studies that compared sub-Tenon's anaesthesia versus topical anaesthesia for cataract surgery. We assessed trial quality and extracted data in the format allowing maximal data inclusion. We included eight studies in this updated review but could retain in the analysis only seven studies on 742 operated eyes of 617 participants. Two cross-over trials included 125 participants, and five parallel trials included 492 participants. These studies were published between 1997 and 2005. The mean age of participants varied from 71.5 years to 83.5 years. The female proportion of participants varied from 54% to 76%. Compared with sub-Tenon's anaesthesia, topical anaesthesia (with or without intracameral injection) for cataract surgery increases intraoperative pain but decreases postoperative pain at 24 hours. The amplitude of the effect (equivalent to 1.1 on a score from 0 to 10 for intraoperative pain, and to 0.2 on the same scale for postoperative pain at 24 hours), although statistically

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.

The Gd-DTPA-enhanced magnetic resonance findings in two patients with herniated thoracic intervertebral discs are reported. The first patient was a 56-year-old woman with a small subligamentous T6-7 disc herniation, slightly lateralized to the right. The second patient was a 51-year-old man with a central and right posterolateral disc herniation, including a large calcified fragment, at the T8-9 level. The nonenhanced MR examination revealed the presence of an extradural mass lesion in both patients, impinging upon the dural sac and compressing and displacing the spinal cord posteriorly. The lesion was slightly hypointense on both T1- and T2-weighted spin echo sequences. Following intravenous injection of Gd-DTPA in a dosage of 0.1 mmol/kg body weight, enhancement of the posterior longitudinal ligament was noted and triangular areas of contrast uptake were seen to occur in the epidural space above and below the herniated disc. At surgery, they were found to correspond to dilated and congested epidural veins. (orig.)

COMPARISON OF EFFECT OF MAGNESIUM SULPHATE AND PRESERVATIVE-FREE KETAMINE AS AN ADJUNCT TO EPIDURAL BUPIVACAINE FOR POSTOPERATIVE ANALGESIA IN ABDOMINAL HYSTERECTOMY

Full Text Available BACKGROUND Neuraxial blocks are the most common method of anaesthesia in abdominal hysterectomies and epidural technique has been used widely to provide both anaesthesia and postoperative analgesia. It has become a common practice to use polypharmacy approach for treatment of intra and postoperative pain, because no drug has yet been identified that specifically inhibit nociception without side effects. The aim of the study is to compare the effects of magnesium sulphate versus preservative-free ketamine as an adjunct to epidural bupivacaine for postoperative analgesia in abdominal hysterectomy. MATERIALS AND METHODS After obtaining informed consent, the patients were divided into 3 groups of 40 each to receive 20 mL 0.5% bupivacaine (group B, 19 mL 0.5% bupivacaine + 50 mg magnesium sulphate (group BM, 19 mL 0.5% bupivacaine + 50 mg preservative-free ketamine (group BK. Epidural catheter was inserted at L1-L2 space using standard technique. Correct placement was confirmed by a test dose of 2% lignocaine + adrenaline 1 in 2 lakhs. Postoperative analgesia were assessed by VAS score and 0.125% bupivacaine infusion and 1 g paracetamol IV infusion was given as rescue analgesics when VAS ≥4. Onset duration, motor block and side effects were also monitored. RESULTS Mean time of duration of onset in group B, BM, BK were 20, 14, 18 minutes, respectively. Mean time for rescue analgesia were 180, 240 and 480 minutes in group 1, 2 and 3, respectively. These differences were statistically significant. The side effects noticed in each group were not statistically significant. CONCLUSION The onset of effect is faster when magnesium sulphate were added as an adjunct to bupivacaine as compared to preservativefree ketamine. The postoperative analgesia is found to be more with preservative-free ketamine as compared to magnesium sulphate without any significant side effects.

Full Text Available We report a case of disseminated neuroblastoma (NB causing epidural spinal cord compression in a 67-year-old woman. Because NB is primarily a tumor of infancy and childhood, less is known about its clinical course and optimal treatment in adults. This patient was treated with a thoracic laminectomy and tumor resection; polychemotherapy with one cycle of vindesine, cisplatin, and etoposide; one cycle of vincristine, dacarbazine, ifosfamide, and doxorubicin; and radiotherapy to the spine. She remained able to walk but died 8.5 months later of diffuse systemic tumor progression.

Full Text Available Perioperative Thoracic epidural analgesia (TEA is an important part of a multimodal approach to improve analgesia and patient outcome after cardiac and thoracic surgery. This is particularly important for obese patients undergoing off pump coronary artery bypass surgery (OPCAB. We conducted a randomized clinical trial at tertiary care cardiac institute to compare the effect of TEA and conventional opioid based analgesia on perioperative lung functions and pain scores in obese patients undergoing OPCAB. Sixty obese patients with body mass index> 30 kg/m 2 for elective OPCAB were randomized into two groups (n=30 each. Patients in both the groups received general anesthesia but in group 1, TEA was also administered. We performed spirometry as preoperative assessment and at six hours, 24 hours, second, third, fourth and fifth day after extubation, along with arterial blood gases analysis. Visual analogue scale at rest and on coughing was recorded to assess the degree of analgesia. The other parameters observed were: time to endotracheal extubation, oxygen withdrawal time and intensive care unit length of stay. On statistical analysis there was a significant difference in Vital Capacity at six hours, 24 hours, second and third day postextubation. Forced vital capacity and forced expiratory volume in one second followed the same pattern for first four postoperative days and peak expiratory flow rate remained statistically high till second postoperative day. ABG values and PaO 2 /FiO 2 ratio were statistically higher in the study group up to five days. Visual analogue scale at rest and on coughing was significantly lower till fourth and third postoperative day respectively. Tracheal extubation time, oxygen withdrawal time and ICU stay were significantly less in group 1. The use of TEA resulted in better analgesia, early tracheal extubation and shorter ICU stay and should be considered for obese patients undergoing OPCAB.

The use of local anaesthesia in ruminants allows many surgical procedures to be conducted free of pain, efficiently and inexpensively in the field. Local anaesthesia combined with sedation and immobilisation of the animal can replace general anaesthesia for many procedures (e. g. castration, claw amputation). The level of difficulty differs among various local anaesthetic techniques: local infiltration of tissue or anaesthesia of the cornual nerve are easily performed, whereas local anaesthesia of the eye, regional anaesthesia in limbs or anaesthesia for umbilical surgery are more difficult to carry out. This article presents an illustrated overview of the most common local anaesthetic procedures in cattle as well as in small ruminants and serves as a practical guide for veterinarians in the field. In principle, these techniques can likewise be applied in other ruminants or artiodactyls.

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

Epidural blood flow was measured in seven patients undergoing elective abdominal surgery during combined lumbar epidural and general anesthesia. After an initial dose of 20 ml plain bupivacaine 0.5%, a continuous epidural infusion of bupivacaine 0.5% (8 ml/hr) was given for 16 hours...... for postoperative pain relief. The epidural blood flow was measured by a local 133Xe clearance technique in which 15-35 MBq 133Xe diluted in 1 ml saline was injected through the epidural catheter on the day before surgery (no bupivacaine), 30 minutes after the initial dose of bupivacaine on the morning before...... surgery, and 8, 12, and 16 hours later during the continuous infusion. Initial blood flow was 6.0 +/- 0.7 ml/min per 100 g tissue (mean +/- SEM). After epidural bupivacaine, blood flow increased in all seven patients to 7.4 +/- 0.7 ml (P less than 0.02). Initial level of sensory analgesia was T4.5 +/- 0...

2003-01-01

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

Full Text Available Anaesthesia ventilators are an integral part of all modern anaesthesia workstations. Automatic ventilators in the operating rooms, which were very simple with few modes of ventilation when introduced, have become very sophisticated with many advanced ventilation modes. Several systems of classification of anaesthesia ventilators exist based upon various parameters. Modern anaesthesia ventilators have either a double circuit, bellow design or a single circuit piston configuration. In the bellows ventilators, ascending bellows design is safer than descending bellows. Piston ventilators have the advantage of delivering accurate tidal volume. They work with electricity as their driving force and do not require a driving gas. To enable improved patient safety, several modifications were done in circle system with the different types of anaesthesia ventilators. Fresh gas decoupling is a modification done in piston ventilators and in descending bellows ventilator to reduce th incidence of ventilator induced volutrauma. In addition to the conventional volume control mode, modern anaesthesia ventilators also provide newer modes of ventilation such as synchronised intermittent mandatory ventilation, pressure-control ventilation and pressure-support ventilation (PSV. PSV mode is particularly useful for patients maintained on spontaneous respiration with laryngeal mask airway. Along with the innumerable benefits provided by these machines, there are various inherent hazards associated with the use of the ventilators in the operating room. To use these workstations safely, it is important for every Anaesthesiologist to have a basic understanding of the mechanics of these ventilators and breathing circuits.

Caranza, R; Jeyapalan, I; Buggy, D J

1999-04-01

In a prospective, randomized, double-blind study in 55 women undergoing elective caesarean section under spinal anaesthesia, we compared epidural diamorphine 3 mg (2 distinct boluses, group ED) with single-dose intrathecal morphine 0.2 mg (group SM), in terms of analgesic efficacy, patient satisfaction and side-effects at 2, 3, 4, 8, 12, 16, 24 and 28 h postoperatively. There were no significant differences between groups in pain (assessed by 100 mm visual analogue scale), incidence of pruritus, sedation or respiratory depression measured by continuous pulse oximetry. However, time to first request for supplementary oral analgesia was longer in SM than in ED (mean +/- SD: 22.3+/-12.0 h vs. 13.8+/-6.5 h, P=0.04). The incidence of nausea or vomiting was significantly higher in SM than ED (73% vs. 41%, P=0.01). In ED, the mean +/- SD time to requirement of the second bolus was 6.7+/-3.2 h. There was a high level of satisfaction in both groups. We conclude that two boluses of epidural diamorphine 3 mg and single-dose intrathecal morphine 0.2 mg provide satisfactory analgesia after caesarean section, but spinal morphine was associated with both delayed requirement for supplementary analgesia and a higher incidence of nausea and vomiting.

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.

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

To conduct a cost analysis of injection laryngoplasty performed in the operating theatre under local anaesthesia and general anaesthesia. The retrospective study included patients who had undergone injection laryngoplasty as day cases between July 2013 and March 2016. Cost data were obtained, along with patient demographics, anaesthetic details, type of injectant, American Society of Anesthesiologists score, length of stay, total operating theatre time and surgeon procedure time. A total of 20 cases (general anaesthesia = 6, local anaesthesia = 14) were included in the cost analysis. The mean total cost under general anaesthesia (AU$2865.96 ± 756.29) was significantly higher than that under local anaesthesia (AU$1731.61 ± 290.29) (p costs. Procedures performed under local anaesthesia in the operating theatre are associated with shorter operating theatre time and length of stay in the hospital, and provide significant cost savings. Further savings could be achieved if local anaesthesia procedures were performed in the office setting.

Full Text Available During current medical care, perioperative transesophageal echocardiography (TEE has become a vital component of patient management, especially in cardiac operating rooms and in critical care medicine. Information derived from echocardiography has an important bearing on the patient′s outcome. The Indian Association of Cardiovascular and Thoracic Anaesthesiologists (IACTA has promoted the use of TEE during routine clinical care of patients undergoing cardiac surgery. An important mission of IACTA is to oversee training and certify anesthesiologists in the perioperative and intensive care use of TEE. The provision of "Fellowship" is by way of conducting IACTA - TEE fellowship (F-TEE examination. This has been done annually for the past 7 years using well-established curriculums by accredited national and international societies. Now, with the transformation and reconstitution of IACTA education and research cell into the newly formed Indian College of Cardiac Anaesthesia, F-TEE is bound to meet international standards. To ensure that the examinations are conducted in a transparent and foolproof manner, the guideline committee (formulated in 2010 of IACTA has taken the onus of formulating the guidelines for the same. These guidelines have been formally reviewed and updated since 2010 and are detailed here to serve as a guide to both the examinee and examiner ensuring standardization, efficiency, and competency of the IACTA F-TEE certification process.

Postoperative intracranial epidural haematoma (EDH) is an extremely rare complication following spinal surgery, with only a handful of cases described in the literature. We report the case of a 16-year-old girl who underwent a successful subtotal resection of a giant lumbosacral schwannoma (L2-S2 level). Recovery from general anaesthesia was uneventful; however, her neurological status deteriorated rapidly within 24 h after surgery. A head computed tomography scan revealed a large right frontoparietal EDH with midline shift. An immediate frontotemporoparietal osteoplastic craniotomy and evacuation of the EDH were performed. At 1 year postoperatively, the patient regained full neurological recovery with no radiological signs of growth of the residual tumour. © 2017 S. Karger AG, Basel.

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.

Full Text Available Pulmonary embolism during or after regional anaesthesia is although very rare, it has been reported in cases undergoing lower limb orthopedic procedures. We presenting a 48 years old male, a known smoker since 25 years, with history of road traffic accident and open fracture right femur for external fixation. Combined spinal epidural anaesthesia was given. After 35 minutes patient complained dyspnea and chest pain. SpO2 decreased to 82% from 100%. Continuous positive airway pressure with 100% oxygen was given. SpO2 increased from 82% to 96%. Suddenly he had bouts of cough and SpO2 became 79-80% with unstable haemodynamics. On chest auscultation there was decreased breath sounds on right side with limited expansion. Trachea was intubated after inducing anaesthesia with fentanyl 70 μg and thiopental 300 mg. Chest radiograph showed right sided pneumothorax. Intercostal drain with a water seal was put. After 5 minutes HR was 80/min, BP was 110/69 mmHg and SpO2 was 97%. Pulmonary thromboembolism secondary to deep vein thrombosis was suspected and was confirmed by D-dimer Elisa and color Doppler of lower limbs. Patient was shifted to intensive care unit after completion of surgery. Anticoagulant therapy was started. He was weaned from the ventilator on 3rd day and trachea was extubated. Chest drain was removed after 9 days and he was discharged from hospital on 15th post operative day

Ten juvenile green iguanas (Iguana iguana) of mean body weight (±SD) 480 ± 134 g. Alfaxalone was administered IM in the triceps of both thoracic limbs. Times for anaesthetic induction, plateau and recovery periods were recorded. Skeletal muscle tone of the jaw, neck, thoracic limbs, pelvic limbs, and tail was scored. The palpebral, corneal and righting reflexes, and the response to painful stimuli were also assessed. Pulse rate and respiratory rate were recorded. Comparisons between different dosages and over time were made using anova. Times are given for 10, 20 and 30 mg kg(-1) dosages respectively: mean time to maximal effect was 7.7 ± 2.2, 5.4 ± 1.7 and 3.9 ± 1.2 minutes; duration of the plateau phase was 11.3 ± 3.8, 22.1 ± 6.5 and 39.1 ± 11.5 minutes; recovery time was 10 ± 2.4, 17.5 ± 8.6 and 25 ± 7.1 minutes; and total anaesthetic duration was 29 ± 35.7, 45 ± 8.2 and 68 ± 9.8 inutes. Endotracheal intubation was possible in 40% of the subjects given 10 mg kg(-1) and in 100% subjects given both 20 and 30 mg kg(-1) . Loss of response to a painful stimulus was seen in 0/10, 8/10 and 9/10 animals at 10, 20, and 30 mg kg(-1) respectively. There was an initial dose-dependent depression of respiration followed by a significant increase in frequency over time. In contrast, pulse rates decreased by 20% over the duration of the anaesthetic events. Intramuscular administration of alfaxalone is a simple, rapid and reliable means of achieving relatively brief sedation or anaesthesia in healthy green iguanas. A dosage of 10 mg kg(-1) provides light sedation, appropriate for examination and venipuncture; 20 mg kg(-1) provides a level suitable for minor procedures or for endotracheal intubation and supplementation with

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

2016-01-01

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

Thyroidectomy is usually performed under general anaesthesia with endotracheal intubation. Bilateral cervical plexus block has been occasionally used as sole anaesthesia technique for this operation in certain parts of world. Indications for regional anaesthesia elsewhere in the world are patient's preference and associated marked cardio-respiratory disease. This is the first report of thyroidectomy done solely under bilateral cervical plexus block in Pakistan. The patient had thyroid cancer and was medically compromised due to cardiac failure with ejection fraction of 25%. Bilateral cervical plexus block was performed to avoid the high risk with general anaesthesia. Total thyroidectomy was done while patient remained painfree during the procedure and top-up local anaesthetic infiltration was not required. Patient remained stable without any morbidity. Positive experience from this case indicates that regional anaesthesia with monitored anaesthesia care is safer than general anaesthesia in high risk patients and could be offered to selective thyroidectomy candidates.

Here we report our experience of a neuroprotective adaptation of the technique of CT-guided radiofrequency (RF) ablation of spinal osteoid osteomas. Over 9 years seven patients underwent eight CT-guided RF treatments for osteoid osteoma. CT-guided RF ablation was performed with general anaesthesia. The lesion was heated to 90 C for 2 min for two cycles by using a Cosman SMK TC-10 RF electrode. This was preceded by a bolus of room temperature sterile water (10 ml) injected through a 26G curved spinal needle into the exit foramen and adjacent epidural space for neuroprotection. The age of the patient, sex, lesion location, biopsy results and complications were recorded. All the biopsies (n = 7) demonstrated histological features of osteoid osteoma. All the procedures were technically successful. Clinical success was assessed up to 3 years post procedure. There was an 85% clinical success rate (6 of the 7 patients), with recurrence of a lesion at 6 months, necessitating a repeat procedure (successful). CT-guided percutaneous RF ablation of spinal osteoid osteoma preceded by bolus of sterile water, injected through a spinal needle into the exit foramen and adjacent epidural space for neuroprotection, is a safe and effective procedure.

This PhD thesis in human-computer interfaces (informatics) studies the case of the anaesthesia record used during medical operations and the possibility to supplement it with speech recognition facilities. Problems and limitations have been identified with the traditional paper-based anaesthesia...... and inaccuracies in the anaesthesia record. Supplementing the electronic anaesthesia record interface with speech input facilities is proposed as one possible solution to a part of the problem. The testing of the various hypotheses has involved the development of a prototype of an electronic anaesthesia record...... interface with speech input facilities in Danish. The evaluation of the new interface was carried out in a full-scale anaesthesia simulator. This has been complemented by laboratory experiments on several aspects of speech recognition for this type of use, e.g. the effects of noise on speech recognition...

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.

Full Text Available Se presenta el caso de un paciente con hematoma epidural subagudo, temporoparietal derecho, secundario a una agresión física. En el cuadro clínico, a las 24 h, predominó la cefalea de intensidad moderada, con somnolencia y agitación psicomotora ligera. Las radiografías simples de cráneo no mostraron alteraciones. 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.

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

Full Text Available 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.

Open surgery for thoracic aortic disease is associated with significant morbidity and the reported rates for paraplegia and stroke are 3%-19% and 6%-11%, respectively. Spinal cord ischemia and stroke have also been reported following endoluminal repair. This study reviews the incidence of paraplegia and stroke in a series of 186 patients treated with thoracic stent grafts. From July 1997 to September 2006, 186 patients (125 men) underwent endoluminal repair of thoracic aortic pathology. Mean age was 71 years (range, 17-90 years). One hundred twenty-eight patients were treated electively and 58 patients had urgent procedures. Anesthesia was epidural in 131, general in 50, and local in 5 patients. Seven patients developed paraplegia (3.8%; two urgent and five elective). All occurred in-hospital apart from one associated with severe hypotension after a myocardial infarction at 3 weeks. Four of these recovered with cerebrospinal fluid (CSF) drainage. One patient with paraplegia died and two had permanent neurological deficit. The rate of permanent paraplegia and death was 1.6%. There were seven strokes (3.8%; four urgent and three elective). Three patients made a complete recovery, one had permanent expressive dysphasia, and three died. The rate of permanent stroke and death was 2.1%. Endoluminal treatment of thoracic aortic disease is an attractive alternative to open surgery; however, there is still a risk of paraplegia and stroke. Permanent neurological deficits and death occurred in 3.7% of the patients in this series. We conclude that prompt recognition of paraplegia and immediate insertion of a CSF drain can be an effective way of recovering spinal cord function and improving the prognosis

Epidural venous stasis in spinal stenosis

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.)

Anaesthesia medical workforce in New Zealand.

King, S Y

This survey was conducted in all 28 New Zealand District Health Boards with a response rate of 100%. The Clinical Directors of Departments of Anaesthesia were asked to quantify their current anaesthesia service delivery and to assess their workforce level. Over half of the District Health Boards reported understaffing, fifty percent occurring in hospitals of provincial cities or towns with an inability to attract specialist anaesthesia staff. Financial constraint was the other main reason for understaffing. With the information from the survey, an attempt was made to predict future New Zealand anaesthesia workforce requirements. A model for Australasia established by Baker in 1997 was used. In comparing this survey to previous studies, there is evidence that the nature and expectations of the anaesthesia workforce are changing as well as the work environment. Currently, there is no indication that anaesthesia specialist training numbers should be reduced. Close, ongoing monitoring and planning are essential to ensure future demands for anaesthesia services can be met.

A prospective, randomized, blinded-endpoint, controlled study - continuous epidural infusion versus programmed intermittent epidural bolus in labor analgesia

Directory of Open Access Journals (Sweden)

Joana Nunes

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

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

Full Text Available The sympathetic block is widely used for treating neuropathic pain such as complex regional pain syndrome (CRPS. However, single sympathetic block often provides only short-term effect. Moreover, frequent procedures for sympathetic block may increase the risk of complications. The use of epidural route may be limited by concern of infection in case of previous implantation of the spinal cord stimulation (SCS. In contrast, a continuous sympathetic block can be administered without such concerns. The continuous thoracic sympathetic block (TSGB has been used to treat the ischemic disease and other neuropathic conditions such as postherpetic neuralgia. We administered continuous thoracic sympathetic block using catheter in CRPS patients who underwent SCS implantations and achieved desirable outcomes. We believe a continuous sympathetic block is a considerable option before performing neurolysis or radiofrequency rhizotomy and even after SCS implantation.

Regional anaesthetic techniques have been used in combination with systemic analgesics during small animal surgery to provide multimodal analgesia. Brachial plexus nerves block using local anaesthetics provides analgesia of the thoracic limb through desensitization of the nerves that provide sensory and motor innervation. This has been shown to reduce intra-operative anesthetic requirements and provide postoperative pain relief. Decreasing the doses of general anaesthetics allows more stable cardiopulmonary function during anaesthesia and the development of less side effects. The present case reports a successful use of brachial plexus blockade to supplement medetomidine-ketamine-isoflurane anaesthesia for repair of radio-ulna fracture in an adult cheetah (acinonyx jubatus). An adult male Cheetah weighing about 65 kg was presented with a history of leg carrying lameness of the left forelimb sustained following a car accident a week earlier. Clinical examination under general anaesthesia revealed slight dehydration and a swelling with a wound on the caudo-medial aspect of the left radio-ulna region. Crepitation was present on manipulation and radiography confirmed a complete transverse radio-ulna fracture of the left forelimb, which required open reduction and internal fixation. Brachial plexus blockade using lignocaine hydrochloride was used to supplement medetomidine-ketamine-isoflurane anaesthesia for the surgical procedure. Isoflurane anaesthesia was maintained at 0.5 - 2.0% throughout the surgical procedure, which was uneventful. Temperature and cardio-pulmonary parameters remained stable intra-operatively. Limb paralysis extended for 5 hours post-operatively, suggesting prolonged anaesthesia. To the researchers' knowledge, this is the first reported case of the use of brachial plexus blockade to supplement general anaesthesia to facilitate forelimb surgery in an adult cheetah. The use of brachial plexus block with a light plane of general anaesthesia proved to

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

Ethamsylate and blood loss in total hip replacement.

Keith, I

1979-01-01

Nineteen consecutive patients undergoing total hip replacement under epidural anaesthesia were randomly divided into two groups. The treatment group received 1000 mg of ethamsylate intravenously before induction of anaesthesia. Blood lost during surgery was measured by a colorimetric technique. Closed suction drains were used and all blood lost after operation collected for measurement. Ethamsylate did not decrease the average volumes of blood lost during or after the operation. Neither did it reduce the requirements for blood transfusion. Although there were no side-effects attributable to ethamyslate, there seems to be no indication for its use in total hip replacement under epidural anaesthesia.

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)

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

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

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

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.

Labor epidural analgesia: Past, present and future

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.

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.

Central neuraxial blocks (CNB: epidural, spinal and their combinations) and other spinal pain procedures can cause serious harm to the spinal cord in patients on antihaemostatic drugs or who have other risk-factors for bleeding in the spinal canal. The purpose of this narrative review is to provide a practise advisory on how to reduce risk of spinal cord injury from spinal haematoma (SH) during CNBs and other spinal pain procedures. Scandinavian guidelines from 2010 are part of the background for this practise advisory. We searched recent guidelines, PubMed (MEDLINE), SCOPUS and EMBASE for new and relevant randomised controlled trials (RCT), case-reports and original articles concerning benefits of neuraxial blocks, risks of SH due to anti-haemostatic drugs, patient-related risk factors, especially renal impairment with delayed excretion of antihaemostatic drugs, and specific risk factors related to the neuraxial pain procedures. Epidural and spinal analgesic techniques, as well as their combination provide superior analgesia and reduce the risk of postoperative and obstetric morbidity and mortality. Spinal pain procedure can be highly effective for cancer patients, less so for chronic non-cancer patients. We did not identify any RCT with SH as outcome. We evaluated risks and recommend precautions for SH when patients are treated with antiplatelet, anticoagulant, or fibrinolytic drugs, when patients' comorbidities may increase risks, and when procedure-specific risk factors are present. Inserting and withdrawing epidural catheters appear to have similar risks for initiating a SH. Invasive neuraxial pain procedures, e.g. spinal cord stimulation, have higher risks of bleeding than traditional neuraxial blocks. We recommend robust monitoring routines and treatment protocol to ensure early diagnosis and effective treatment of SH should this rare but potentially serious complication occur. When neuraxial analgesia is considered for a patient on anti

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. 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. 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.

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

Full Text Available During the inhalation of anaesthesia use of low fresh gas flow (0.35-1 L/min has some important advantages. There are three areas of benefit: pulmonary - anaesthesia with low fresh gas flow improves the dynamics of inhaled anaesthesia gas, increases mucociliary clearance, maintains body temperature and reduces water loss. Economic - reduction of anaesthesia gas consumption resulting in significant savings of > 75% and Ecological - reduction in nitrous oxide consumption, which is an important ozone-depleting and heat-trapping greenhouse gas that is emitted. Nevertheless, anaesthesia with high fresh gas flows of 2-6 L/min is still performed, a technique in which rebreathing is practically negligible. This special article describes the clinical use of conventional plenum vaporizers, connected to the fresh gas supply to easily perform low (1 L/min, minimal (0.5 L/min or metabolic flow anaesthesia (0.35 L/min with conventional Primus Draeger® anaesthesia machines in routine clinical practice.

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

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)

The purpose of this study was to evaluate if pre-anaesthetic thoracic radiographs contribute to the anaesthetic management of trauma patients by comparing American Society of Anesthesiologists Physical Status Classification (ASA grade) with and without information from thoracic radiography findings. Case records of 157 dogs and cats being anaesthetized with or without post-traumatic, pre-anaesthetic chest radiographs were retrospectively evaluated for clinical parameters, radiographic abnormalities and anaesthetic protocol. Animals were retrospectively assigned an ASA grade. ASA grades, clinical signs of respiratory abnormalities and anaesthesia protocols were compared between animals with and without chest radiographs. The group of animals without pre-anaesthetic radiographs was anaesthetized earlier after trauma and showed less respiratory abnormalities at presentation. The retrospectively evaluated ASA grade significantly increased with the information from thoracic radiography. Animals with a higher ASA grade were less frequently mechanically ventilated. Pre-anaesthetic radiographs may provide important information to assess the ASA grade in traumatized patients and may therefore influence the anesthesia protocol

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.

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

The dietary intake allowed during the latent and active phases of labour varies between Canadian hospitals. Our objective was to document current restrictions on oral and parenteral intake for low-risk labouring women in hospitals across Canada. We carried out a cross-sectional study of 118 Canadian hospitals that have specialized birthing centres. Information on dietary protocols for low-risk women in labour was obtained from each hospital via a brief telephone interview with the head nurse of each birthing centre. Data were presented by stage of labour, both with and without epidural anaesthesia, and also by dextrose supplementation of intravenous fluids. If epidural anaesthesia was not used during the active phase of labour, oral intake was restricted to clear fluids and/or ice chips in 50.9% of surveyed hospitals and oral intake could include solid food in 38.1%. However, when epidural anaesthesia was used during the active phase of labour, oral intake was restricted to clear fluids and ice chips in 82.8% of surveyed hospitals, while oral intake could include solid food in 7.2%. Furthermore, in 77.5% of hospitals, not only was oral intake during active labour with epidural anaesthesia limited to clear fluids and/or ice chips, but in addition this restrictive diet was not supplemented with parenteral dextrose. The majority of low-risk pregnant women in Canadian hospitals are subjected to caloric restriction during the active phase of labour, especially when epidural anaesthesia is administered. Further studies on this subject are warranted because such pervasive practices may have important population effects on labouring women.

Tadrous, R

2011-07-01

Sturge-Weber syndrome consists of facial capillary malformation (port-wine stain) and abnormal blood vessels in the brain or eye. Seizures, developmental delay and intracranial and airway angiomata are principal concerns. We report a 28-year-old primiparous woman at 41 weeks of gestation with Sturge-Weber syndrome who developed unilateral weakness, aphasia, blurred vision and confusion. Preeclampsia was excluded. Neuroimaging showed left sided cerebral oedema and a right parieto-occipital lesion, most likely an angioma. Caesarean section was planned to avoid the risk of angioma rupture during labour. General anesthesia was avoided due to the haemodynamic response to laryngoscopy and reports of seizure-related mortality. Despite the possibility of raised intracranial pressure and precipitation of cerebral herniation, a lumbar epidural block was administered but failed. A subarachnoid block was successfully performed and a healthy infant delivered. The choice of anaesthesia was strongly influenced by detailed radiological investigations and multidisciplinary participation.

Secondary spontaneous pneumothorax (SSP) is serious entity, usually due to underlying disease, mainly chronic obstructive pulmonary disease (COPD). Its morbidity and mortality is high due to the pulmonary compromised status of these patients, and the recurrence rate is almost 50%, increasing mortality with each episode. For persistent or recurrent SSP, surgery under general anesthesia (GA) and mechanical ventilation (MV) with lung isolation is the gold standard, but ventilator-induced damages and dependency, and postoperative pulmonary complications are frequent. In the last two decades, several groups have reported successful results with non-intubated video-assisted thoracic surgery (NI-VATS) with thoracic epidural anesthesia (TEA) and/or local anesthesia under spontaneous breathing. Main benefits reported are operative time, operation room time and hospital stay reduction, and postoperative respiratory complications decrease when comparing to GA, thus encouraging for further research in these moderate to high risk patients many times rejected for the standard regimen. There are also reports of special situations with satisfactory results, as in contralateral pneumonectomy and lung transplantation. The aim of this review is to collect, analyze and discuss all the available evidence, and seek for future lines of investigation.

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

We present the main findings of the 5th National Audit Project on accidental awareness during general anaesthesia. Incidences were estimated using reports of accidental awareness as the numerator, and a parallel national anaesthetic activity survey to provide denominator data. The incidence of certain/probable and possible accidental awareness cases was ~1:19 600 anaesthetics (95% CI 1:16 700-23 450). However, there was considerable variation across subtypes of techniques or subspecialties. The incidence with neuromuscular blockade was ~1:8200 (1:7030-9700), and without it was ~1:135 900 (1:78 600-299 000). The cases of accidental awareness during general anaesthesia reported to 5th National Audit Project were overwhelmingly cases of unintended awareness during neuromuscular blockade. The incidence of accidental awareness during caesarean section was ~1:670 (1:380-1300). Two thirds (82, 66%) of cases of accidental awareness experiences arose in the dynamic phases of anaesthesia, namely induction of and emergence from anaesthesia. During induction of anaesthesia, contributory factors included: use of thiopental; rapid sequence induction; obesity; difficult airway management; neuromuscular blockade; and interruptions of anaesthetic delivery during movement from anaesthetic room to theatre. During emergence from anaesthesia, residual paralysis was perceived by patients as accidental awareness, and commonly related to a failure to ensure full return of motor capacity. One third (43, 33%) of accidental awareness events arose during the maintenance phase of anaesthesia, most due to problems at induction or towards the end of anaesthesia. Factors increasing the risk of accidental awareness included: female sex; age (younger adults, but not children); obesity; anaesthetist seniority (junior trainees); previous awareness; out-of-hours operating; emergencies; type of surgery (obstetric, cardiac, thoracic); and use of neuromuscular blockade. The following factors were

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.

Neural-Dural Transition at the Thoracic and Lumbar Spinal Nerve Roots: A Histological Study of Human Late-Stage Fetuses

2016-01-01

Full Text Available Epidural blocks have been used extensively in infants. However, little histological information is available on the immature neural-dural transition. The neural-dural transition was histologically investigated in 12 late-stage (28–30 weeks fetuses. The dural sheath of the spinal cord was observed to always continue along the nerve roots with varying thicknesses between specimens and segments, while the dorsal root ganglion sheath was usually very thin or unclear. Immature neural-dural transitions were associated with effective anesthesia. The posterior radicular artery was near the dorsal root ganglion and/or embedded in the nerve root, whereas the anterior radicular artery was separated from the nearest nerve root. The anterior radicular artery was not associated with the dural sheath but with thin mesenchymal tissue. The numbers of radicular arteries tended to become smaller in larger specimens. Likewise, larger specimens of the upper thoracic and lower lumbar segments did not show the artery. Therefore, elimination of the radicular arteries to form a single artery of Adamkiewicz was occurring in late-stage fetuses. The epidural space was filled with veins, and the loose tissue space extended ventrolaterally to the subpleural tissue between the ribs. Consequently, epidural blocks in infants require special attention although immature neural-dural transitions seemed to increase the effect.

Epidural analgesia during labor vs no analgesia: A comparative study

Directory of Open Access Journals (Sweden)

Wesam Farid Mousa

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.

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.

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)

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

Inadvertent injection of succinylcholine as an epidural test dose

Directory of Open Access Journals (Sweden)

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.

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

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.)

This study aimed to compare the analgesic efficacy and the influence of local infiltrative anesthesia techniques, with diploe anesthesia, on the cardiac rhythmMaterial and Methods: We selected 32 healthy volunteers who were given both anaesthetic techniques on tooth 1.4 (0.45 mL of lidocaine with adrenaline, 1:80 000). In the first phase, the volunteers underwent periapical infiltrative anaesthesia. In the second phase, diploe anaesthesia was performed with a QuickSleeper® device. The parameters analysed were pulp response to the electrical test and heart rate of the participants. These parameters were evaluated on five different occasions: before anaesthesia (t0), immediately after anaesthesia (t1), 15 minutes later (t15), 30 minutes later (t30) and 60 minutes later (t60). Statistical analysis of the data was performed using SPSS 2.0 software, with α = 0.05. With the diploe anaesthesia, a level of analgesia was obtained faster. There was a slight increase in heart rate soon after administration of diploe anaesthesia, which stabilized after t15 of the procedure. This technique still proved to be painless. Diploe anaesthesia demonstrated better results in terms of analgesia than the infiltrative anaesthesia. It has been reported to be easy, safe and an effective procedure that allows anaesthesia in almost all clinical situations. This approach may offer particular advantages for endodontic therapy, providing greater comfort for the patient.

Unusual Spinal Epidural Lipomatosis and Lumbosacral Instability

2016-01-01

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.

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

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.

Epidural und subdural spinal hematomas were previously diagnosed by myelography and computed tomography (CT). Recent reports indicate that noninvasive detection is possible with magnetic resonance imaging. We report on nine patients who were investigated by magnetic resonance imaging (MR) prior to surgery for epidural and subdural spinal hematoma. The MR examinations were performed on 1.5-T and 1-T units. We used surface coils and employed T1-, PD- and T2-weighted spin echo sequences and a T2*-weighted gradient echo sequence. CT was available in four patients and myelography in two patients. Surgical correlation was available in all patients. The hematomas were located in the cervical spine (n=2), thoracic spine (n=6) and lumbar spine (n=2). They were epidural in five patients and subdural in four. Blinded reading correctly indentified all five epidural hematomas and three of the subdural hematomas; one subdural hematoma was misjudged as epidural. Peracute hematomas (<24 h) in three patients appeared isointense or slightly hyperintense on T1-weighted images and had mixed signal intensity on T2- and T2*-weighted images. Acute hematomas (1-3 days) in four patients were also isointense on T1-weighted images but were more hypointense on T2- and T2*-weighted images. Chronic heamatomas in two patients (7 days and 14 days) were hyperintense on all sequences. Differentiation between epi- and subdural hematomas required transverse T2*-weighted gradient echo sequences. Our results underline that MRI at 1 and 1.5 T is capable of identifying epidural and subdural spinal hematoma in the acute and peracute stage. MRI is superior to CT and myelography for the delineation of the craniocaudal extension in epidural and subdural spinal hematomas and should be the primary preoperative diagnostic method. (orig.)

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

Deighan, M

2015-03-01

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

WHAT HAPPENS TO INTRAOCULAR PRESSURE AFTER PERIBULBAR ANAESTHESIA?

Krishnamoorthy Segharipuram Ranganathan

Full Text Available BACKGROUND Most of intraocular surgeries are done under local anaesthesia. The peribulbar anaesthesia provides adequate anaesthesia and akinesia. There is no reported intraoperative and/or postoperative amaurosis. The peribulbar anaesthesia provides adequate anaesthesia and akinesia. The disadvantages of it are the larger quantity of the aesthetic agent. Increasing the bulk load on the globe and a reported rise of intraocular pressure. MATERIALS AND METHODS A study of fifty cases was conducted in patients who received peribulbar anaesthesia undergoing cataract extraction with intraocular lens implantation and their intraocular pressures were noted and studied after giving the peribulbar anaesthesia all given by the same surgeon. RESULTS This study did show that the peribulbar anaesthesia increases the intraocular pressure in all the cases. The external ocular compression indeed helps to dissipate the anaesthetic load thereby reducing the enormous rise in IOP, which is only expected if you recollect the fact that the eyeball occupies one sixth of the total volume of the orbit that is 5 mL and 30 mL. The volume of peribulbar anaesthesia (6 mL does add its effects to increase the IOP. Hence, a properly planned post peribulbar compression helps to minimise the transient rise in IOP. CONCLUSION Summarising the study, it is better to give peribulbar injection initially followed by external ocular compression after a delay of at least 2 to 5 minutes. It is also advised that an initial compression maybe given in slightly risk cases, so that the peribulbarinduced rise may not be alarming. The anaesthetic solution maybe fragmented and the second injection maybe delayed by 5 minutes or omitted if good akinesia and anaesthesia are achieved already.

We present the main findings of the 5th National Audit Project (NAP5) on accidental awareness during general anaesthesia (AAGA). Incidences were estimated using reports of accidental awareness as the numerator, and a parallel national anaesthetic activity survey to provide denominator data. The incidence of certain/probable and possible accidental awareness cases was ~1:19,600 anaesthetics (95% confidence interval 1:16,700-23,450). However, there was considerable variation across subtypes of techniques or subspecialities. The incidence with neuromuscular block (NMB) was ~1:8200 (1:7030-9700), and without, it was ~1:135,900 (1:78,600-299,000). The cases of AAGA reported to NAP5 were overwhelmingly cases of unintended awareness during NMB. The incidence of accidental awareness during Caesarean section was ~1:670 (1:380-1300). Two-thirds (82, 66%) of cases of accidental awareness experiences arose in the dynamic phases of anaesthesia, namely induction of and emergence from anaesthesia. During induction of anaesthesia, contributory factors included: use of thiopental, rapid sequence induction, obesity, difficult airway management, NMB, and interruptions of anaesthetic delivery during movement from anaesthetic room to theatre. During emergence from anaesthesia, residual paralysis was perceived by patients as accidental awareness, and commonly related to a failure to ensure full return of motor capacity. One-third (43, 33%) of accidental awareness events arose during the maintenance phase of anaesthesia, mostly due to problems at induction or towards the end of anaesthesia. Factors increasing the risk of accidental awareness included: female sex, age (younger adults, but not children), obesity, anaesthetist seniority (junior trainees), previous awareness, out-of-hours operating, emergencies, type of surgery (obstetric, cardiac, thoracic), and use of NMB. The following factors were not risk factors for accidental awareness: ASA physical status, race, and use or omission

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

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

Primary epidural lymphoma without vertebral involvement in a HIV-positive patient

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

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)

Epidural fat image in lumbar magnetic resonance image

Nishijima, Yuichiro; Yamasaki, Yasuo; Higashida, Norihiko; Okada, Masato

1993-01-01

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

Effective intra-operative anaesthesia and peri-operative analgesia are important aspects of patient care in orthopaedic surgery. The interscalene regional anaesthetic block technique, performed with the patient lying in a lateral decubitus position, is new for arthroscopic shoulder surgery conducted in the Netherlands. The combination of the interscalene block (without general anaesthesia) and the lateral decubitus position results in better peri-operative conditions for the patient. Better analgesia, increased patient satisfaction and fewer complications in comparison to general anaesthesia have been reported for these types of surgery.

[Measurement of the depth of anaesthesia].

Schmidt, G N; Müller, J; Bischoff, P

One of the most important mandates of the anaesthesiologist is to control the depth of anaesthesia. An unsolved problem is that a straight definition of the depth of anaesthesia does not exist. Concerning this it is rational to separate hypnosis from analgesia, from muscle relaxation and from block of cardiovascular reactions. Clinical surrogate parameters such as blood pressure and heart rate are not well-suited for a valid statement about the depth of hypnosis. To answer this question the brain has become the focus of interest as the target of anaesthesia. It is possible to visualize the brain's electrical activity from anelectroencephalogram (EEG). The validity of the spontaneous EEG as an anesthetic depth monitor is limited by the multiphasic activity, especially when anaesthesia is induced (excitation) and in deep anaesthesia (burst suppression). Recently, various commercial monitoring systems have been introduced to solve this problem. These monitoring systems use different interpretations of the EEG or auditory-evoked potentials (AEP). These derived and calculated variables have no pure physiological basis. For that reason a profound knowledge of the algorithms and a validation of the monitoring systems is an indispensable prerequisite prior to their routine clinical use. For the currently available monitoring systems various studies have been reported. At this time it is important to know that the actual available monitors can only value the sedation and not the other components of anaesthesia. For example, they cannot predict if a patient will react to a painful stimulus or not. In the future it would be desirable to develop parameters which allow an estimate of the other components of anaesthesia in addition to the presently available monitoring systems to estimate sedation and muscle relaxation. These could be sensoric-evoked potentials to estimate analgesia and AEPs for the detection of awareness.

Full Text Available BACKGROUND The incidence of breast cancer is on the rise in developing countries. Though, there have been significant advances in general anaesthesia, surgery in elderly and those with comorbid illness still have an attendant morbidity and mortality. After the introduction of local anaesthesia by Kolher in 1884 and in spite of steady refinement, local anaesthesia is still not being widely used in major general surgical procedures. MATERIALS AND METHODS The study was conducted in Government Medical College, Calicut, a tertiary care centre in Kerala. The outcome of Modified Radical Mastectomy performed under Local Anaesthesia (LA and dexmedetomidine infusion was compared to similar cases done under General Anaesthesia (GA. RESULTS Rapid recovery from sedation leading to early restoration of normal physical activity was observed in the LA group when compared to GA group. Early initiation of oral feeds was possible in the former group as Postoperative Nausea and Vomiting (PONV was significantly less. Effective postoperative pain relief and significant reduction in respiratory complications was observed in the LA group compared to GA group. CONCLUSION Modified Radical Mastectomy under LA and procedural sedation with dexmedetomidine was significantly better in selected cases when compared to similar cases done under GA with respect to early recovery pain relief and decreased incidence of respiratory complications.

Ultrasound guidance allows for the use of much lower volumes of local anaesthetics for nerve blocks, which may be associated with less aberrant spread and fewer complications. This randomized, controlled study used contrast magnetic resonance imaging to view the differential-volume local anaesthetic distribution, and compared analgesic efficacy and respiratory impairment. Thirty patients undergoing shoulder surgery were randomized to receive ultrasound-guided interscalene block by a single, blinded operator with injection of ropivacaine 0.75% (either 20 or 5 ml) plus the contrast dye gadopentetate dimeglumine, followed by magnetic resonance imaging. The primary outcome was epidural spread. Secondary outcomes were central non-epidural spread, contralateral epidural spread, spread to the phrenic nerve, spirometry, ultrasound investigation of the diaphragm, block duration, pain scores during the first 24 h, time to first analgesic consumption, and total analgesic consumption. All blocks provided fast onset and adequate intra- and postoperative analgesia, with no significant differences in pain scores at any time point. Epidural spread occurred in two subjects of each group (13.3%); however, spread to the intervertebral foramen and phrenic nerve and extensive i.m. local anaesthetic deposition were significantly more frequent in the 20 ml group. Diaphragmatic paralysis occurred twice as frequently (n=8 vs 4), and changes from baseline peak respiratory flow rate were larger [Δ=-2.66 (1.99 sd) vs -1.69 (2.0 sd) l min(-1)] in the 20 ml group. This study demonstrates that interscalene block is associated with epidural spread irrespective of injection volume; however, less central (foraminal) and aberrant spread after low-volume injection may be associated with a more favourable risk profile. This study was registered with the European Medicines Agency (Eudra-CT number 2013-004219-36) and with the US National Institutes' of Health registry and results base, clinicaltrials

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

2018-03-09

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

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.)

Advantages of thoracic paravertebral analgesia (TPA) include placement of the catheter closer to the surgical field; however, the catheter can become damaged during the operation. We experienced a case of intraoperative TPA catheter breakage that prompted us to perform an experiment to investigate possible causes. A 50-year-old male underwent a thoracoscopic lower lobectomy under general anesthesia with TPA via an intercostal approach. Following surgery, it was discovered that the catheter had become occluded, as well as cut and fused, so we reopened the incision and removed the residual catheter. From that experience, we performed an experiment to examine electrocautery-induced damage in normal (Portex™, Smith's Medical), radiopaque (Perifix SoftTip™, BBraun), and reinforced (Perifix FX™, BBraun) epidural catheters (n = 8 each). Chicken meat was penetrated by each catheter and then cut by electrocautery. In the normal group, breakage occurred in 8 and occlusion in 6 of the catheters, and in the radiopaque group breakage occurred in 8 and occlusion in 7. In contrast, breakage occurred in only 3 and occlusion in none in the reinforced group, with the 5 without breakage remaining connected only by the spring coil. Furthermore, in 7 of the reinforced catheters, electric arc-induced thermal damage was observed at the tip of the catheter. A TPA catheter for thoracic surgery should be inserted via the median approach, or it should be inserted after surgery to avoid catheter damage during surgery.

A qualitative study of regional anaesthesia for vitreo-retinal surgery.

Science.gov (United States)

McCloud, Christine; Harrington, Ann; King, Lindy

2014-05-01

The aim of this research was to collect experiential knowledge about regional ocular anaesthesia - an integral component of most vitreo-retinal surgery. Anaesthesia for vitreo-retinal surgery has predominantly used general anaesthesia, because of the length and complexity of the surgical procedure. However, recent advances in surgical instrumentation and techniques have reduced surgical times; this decision has led to the adoption of regional ocular anaesthesia for vitreo-retinal day surgery. Although regional ocular anaesthesia has been studied from several perspectives, knowledge about patients' experience of the procedure is limited. An interpretive qualitative research methodology underpinned by Gadamer's philosophical hermeneutics. Eighteen participants were interviewed in-depth between July 2006-December 2007 following regional ocular anaesthesia. Interview data were thematically analysed by coding and grouping concepts. Four themes were identified: 'not knowing': the time prior to the experience of a regional eye block; 'experiencing': the experience of regional ocular anaesthesia; 'enduring': the capacity participants displayed to endure regional ocular anaesthesia with the hope that their vision would be restored; and 'knowing': when further surgery was required and past experiences were recalled. The experience of regional ocular anaesthesia had the capacity to invoke anxiety in the participants in this study. Many found the experience overwhelming and painful. What became clear was the participant's capacity to stoically 'endure' regional ocular anaesthesia, indicating the value people placed on visual function. © 2013 John Wiley & Sons Ltd.

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

Delayed epidural hematoma after mild head injury

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.

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

Epidural haematoma: pathophysiological significance of extravasation and arteriovenous shunting

International Nuclear Information System (INIS)

Habash, A.H.; Sortland, O.; Zwetnow, N.N.

1982-01-01

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

Background. The hanging drop (HD) technique presumably relies on the presence of subatmospheric epidural pressure. It is not clear whether this negative pressure is intrinsic or an artifact and how it is affected by body position. There are few data to indicate how often HD is currently being used. Methods. We identified studies that measured subatmospheric pressures and looked at the effect of the sitting position. We also looked at the technique used for cervical and thoracic epidural anesthesia in the last 10 years. Results. Intrinsic subatmospheric pressures were measured in the thoracic and cervical spine. Three trials studied the effect of body position, indicating a higher incidence of subatmospheric pressures when sitting. The results show lower epidural pressure (-10.7 mmHg) with the sitting position. 28.8% of trials of cervical and thoracic epidural anesthesia that documented the technique used, utilized the HD technique. When adjusting for possible bias, the rate of HD use can be as low as 11.7%. Conclusions. Intrinsic negative pressure might be present in the cervical and thoracic epidural space. This effect is more pronounced when sitting. This position might be preferable when using HD. Future studies are needed to compare it with the loss of resistance technique.

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

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

Alternative practices of achieving anaesthesia for dental procedures: a review.

Science.gov (United States)

Angelo, Zavattini; Polyvios, Charalambous

2018-04-01

Managing pain and anxiety in patients has always been an essential part of dentistry. To prevent pain, dentists administer local anaesthesia (LA) via a needle injection. Unfortunately, anxiety and fear that arise prior to and/or during injection remains a barrier for many children and adults from receiving dental treatment. There is a constant search for techniques to alleviate the invasive and painful nature of the needle injection. In recent years, researchers have developed alternative methods which enable dental anaesthesia to be less invasive and more patient-friendly. The aim of this review is to highlight the procedures and devices available which may replace the conventional needle-administered local anaesthesia. The most known alternative methods in providing anaesthesia in dentistry are: topical anaesthesia, electronic dental anaesthesia, jet-injectors, iontophoresis, and computerized control local anaesthesia delivery systems. Even though these procedures are well accepted by patients to date, it is the authors' opinion that the effectiveness practicality of such techniques in general dentistry is not without limitations.

Numerous nurses work in operating rooms and recovery rooms or participate in the performance of anaesthesia in China. However, the scope of practice and the education for Chinese Anaesthesia Nurses is not standardized, varying from one geographic location to another. Furthermore, most nurses are not trained sufficiently to provide anaesthesia care. This study aimed to develop the first Anaesthesia Nurse Education Program in Mainland China based on the Educational Standards of the International Federation of Nurse Anaesthetists. The Delphi technique was applied to develop the scope of practice, competencies for Chinese Anaesthesia Nurses and education program. In 2014 the Anaesthesia Nurse Education Program established by the hospital applied for recognition by the International Federation of Nurse Anaesthetists. The Program's curriculum was evaluated against the IFNA Standards and recognition was awarded in 2015. The four-category, 50-item practice scope, and the three-domain, 45-item competency list were identified for Chinese Anaesthesia Nurses. The education program, which was established based on the International Federation of Nurse Anaesthetists educational standards and Chinese context, included nine curriculum modules. In March 2015, 13 candidates received and passed the 21-month education program. The Anaesthesia Nurse Education Program became the first program approved by the International Federation of Nurse Anaesthetists in China. Policy makers and hospital leaders can be confident that anaesthesia nurses graduating from this Chinese program will be prepared to demonstrate high level patient care as reflected in the recognition by IFNA of their adoption of international nurse anaesthesia education standards.

Shrestha, Bikash; Devgan, Amit; Sharma, Mukti

2014-12-10

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

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

Full Text Available Background : Often conventional Inhalational agents are used for maintenance of anaesthesia in spine surgery. This study was undertaken to compare propofol with isoflurane anaesthesia with regard to haemodynamic stability, early emergence, postoperative nausea and vomiting (PONV and early assessment of neurological functions. Patients & Methods: Eighty ASA grade I &II adult patients were randomly allocated into two groups. Patients in study group received inj propofol for induction as well as for maintenance along with N 2O+O2 and the control group patients received inj thiopentone for induction and N 2 O+O 2 +isoflurane for maintenance. BIS monitoring was used for titrating the anaesthetic dose adjustments in all patients. All patients received fentanyl boluses for intraoperative analgesia and atracurium as muscle relaxant. Statistical data containing haemodynamic parameters, PONV, emergence time, dose of drug consumed & quality of surgical field were recorded and compared using student t′ test and Chi square test. Results: The haemodynamic stability was coparable in both the groups. The quality of surgical field were better in study group. Though there was no significant difference in the recovery profile (8.3% Vs 9.02% between both the groups, the postoperative nausea and vomiting was less in propofol group than isoflurane group (25%Vs60%. The anaesthesia cost was nearly double for propofol than isoflurane anaesthesia. Conclusion: Haemodynamic stability was comparable in both the groups. There was no significant difference in the recovery time between intravenous and inhalational group. Patients in propofol group were clear headed at awakening and were better oriented to place than inhalational group.

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.)

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

LENUS (Irish Health Repository)

2012-02-29

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

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

2010-07-01

Ultrasound equipment is increasingly used by non-radiologists to perform interventional techniques and for diagnostic evaluation. Equipment is becoming more portable and durable, with easier user-interface and software enhancement to improve image quality. While obstetric utilisation of ultrasound for fetal assessment has developed over more than 40years, the same technology has not found a widespread role in obstetric anaesthesia. Within the broader specialty of anaesthesia; vascular access, cardiac imaging and regional anaesthesia are the areas in which ultrasound is becoming increasingly established. In addition to ultrasound for neuraxial blocks, these other clinical applications may be of value in obstetric anaesthesia practice.

Calcified epidural hematoma in pediatric age group: A report of two cases

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

2000-10-01

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.

Fever following an Epidural Blood Patch in a Child

Agnes I. Hunyady

2012-01-01

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

Valvular heart disease and anaesthesia.

Science.gov (United States)

Paul, Abhijit; Das, Sucharita

2017-09-01

Valvular heart disease presents as mixed spectrum lesion in healthcare settings in the third-world and developing countries. Rheumatic heart disease still forms the bulk of the aetiopathology of valve lesions. Mitral and aortic valve lesions top the list of valvular pathology. A thorough understanding of the pathophysiology of valvular heart disease is essential while planning anaesthesia and perioperative care for such patients. Meticulous use of optimal fluids, close monitoring of the changing haemodynamics and avoidance of situations that can cause major reduction of cardiac output and fluid shifts are mandatory to achieve good clinical outcome. We searched MEDLINE using combinations of the following: anaesthesia, aortic, mitral, regurgitation, stenosis and valvular heart disease. We also hand searched textbooks and articles on valvular heart disease and anaesthesia. This article mainly focuses on the understanding the pathophysiology of valvular heart disease in patients presenting for non-cardiac surgeries in secondary and tertiary care setting.

Surgery and anaesthesia may account for postoperative complications including cognitive impairment. The purpose of the study was to assess the influence of general anaesthetics on children's memory and effectiveness of piracetam for prevention of postoperative cognitive dysfunction. The study included patients receiving different kinds of anaesthesia for various surgical procedures, randomly allocated to two groups. According to immediate postoperative treatment, the study group received intravenous piracetam 30 mg kg(-1) and the control group--placebo. The cognitive functions were examined preoperatively and within 10 consecutive postoperative days using the ten-word memory test. The study group consisted of 123 children, the control one--of 127. Declines in memory indexes were observed in all anaesthetized patients. The most injured function was long-term memory. The intravenous administration of piracetam improved this cognitive function. The study results confirm that general anaesthesia affects the memory function in children. Piracetam is effective for prevention of postoperative cognitive dysfunction after anaesthesia.

Recent interest has focused on the role of perioperative epidural analgesia in improving cancer outcomes. The heterogeneity of studies (tumour type, stage and outcome endpoints) has produced inconsistent results. Clinical practice also highlights the variability in epidural effectiveness. We considered the novel hypothesis that effective epidural analgesia improves cancer outcomes following gastro-oesophageal cancer surgery in patients with grouped pathological staging. Following institutional approval, a database analysis identified 140 patients, with 2-year minimum follow-up after gastro-oesophageal cancer surgery. All patients were operated on by a single surgeon (2005-2010). Information pertaining to cancer and survival outcomes was extracted. Univariate analysis demonstrated a 1-year 14% vs. 33% (P = 0.01) and 2-year 27% vs. 40% [hazard ratio (HR)=0.59; 95% CI, 0.32-1.09, P = 0.087] incidence of cancer recurrence in patients with (vs. without) effective (> 36 h duration) epidural analgesia, respectively. Multivariate analysis demonstrated increased time to cancer recurrence (HR = 0.33; 95% CI: 0.17-0.63, P benefit (HR = 0.42; 95% CI: 0.21-0.83, P benefit in patients with oesophageal cancer (HR = 0.34; 95% CI: 0.16-0.75, P = 0.005) and in patients with tumour lymphovascular space infiltration (LVSI), (HR = 0.49; 95% CI: 0.26-0.94, P = 0.03). Effective epidural analgesia improved estimated median time to death (2.9 vs. 1.8 years, P = 0.029) in patients with tumour LVSI. This study found an association between effective post-operative epidural analgesia and medium-term benefit on cancer recurrence and survival following oesophageal surgery. A prospective study that controls for disease type, stage and epidural effectiveness is warranted. © 2014 The Acta Anaesthesiologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.

Anaesthesia generates neuronal insulin resistance by inducing hypothermia

2008-10-01

Full Text Available Abstract Background Anaesthesia is commonly employed prior to surgical investigations and to permit icv injections in rodents. Indeed it is standard practise in many studies examining the subsequent actions of hormones and growth factors on the brain. Recent evidence that the basal activity of specific intracellular signalling proteins can be affected by anaesthesia prompted us to examine the effect of anaesthesia not only on the basal activity but also the insulin sensitivity of the major insulin signalling pathways. Results We find that urethane- and ketamine-induced anaesthesia results in rapid activation of the phosphatidylinositol (PI 3-kinase-protein kinase B (PKB signalling pathway in the brain, increases tau phosphorylation while at the same time reducing basal activity of the Ras-ERK pathway. Subsequent injection of insulin does not alter the activity of either the PI 3-kinase or ERK signalling pathways, indicating a degree of neuronal molecular insulin resistance. However, if body temperature is maintained during anaesthesia then there is no alteration in the basal activity of these signalling molecules. Subsequent response of both pathways to insulin injection is restored. Conclusion The data is consistent with a hypothermia related alteration in neuronal signalling following anaesthesia, and emphasises the importance of maintaining the body temperature of rodents when monitoring insulin (or growth factor/neurotrophic agent action in the brain of anesthetised rodents.

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

The purpose of this review was to analyse post-registration anaesthesia nursing education in the Nordic countries. The analysis was based on key determinants fundamental to analysing nursing education: 1) the sys]tem of anaesthesia nursing education, 2) entry requirements, 3) credits, the duration and the title or degree awarded, and 4) the amount of practical training. A scoping review was approached in a systematic manner. The literature was analysed using deductive content analysis. Data was gathered based on key determinants. The data were quantified into frequencies and percentages to compare the similarities and differences of anaesthesia nursing. The Nordic countries have different types of post-registration anaesthesia nursing education from non-degree supplementary programmes to Master's degree programmes. Even though the entry requirements correspond between countries, many more differences than similarities in anaesthesia nursing education were noted. A title granting the right to work as a nurse anaesthetist can be obtained through a variety of educational systems, credit requirements, the duration, and the amount of practical training in post-registration anaesthesia nursing programmes. This aim of the study was to analyse post-registration anaesthesia nursing education from the Nordic perspective. Harmonising the educational system and minimum education requirements in anaesthesia nursing education is recommended in order to facilitate free movement and assure the quality of care from the Nordic perspective. Since each Nordic country has its own native language, it was difficult to gather information from all the Nordic countries. Therefore, creating common educational database published in English can help to bench mark each country's educational system. Copyright © 2015 Elsevier Ltd. All rights reserved.

Pain during childbirth is arguably the most severe pain some women may experience in their lifetime. Epidural analgesia is an effective form of pain relief during labour. Many women have concerns regarding its safety. Furthermore, epidural services and anaesthetic support may not be available consistently across all centres. Observational data suggest that early initiation of epidural may be associated with an increased risk of caesarean section, but the same findings were not seen in recent randomised controlled trials. More recent guidelines suggest that in the absence of a medical contraindication, maternal request is a sufficient medical indication for pain relief during labour. The choice of analgesic technique, agent, and dosage is based on many factors, including patient preference, medical status, and contraindications. There is no systematically reviewed evidence on the maternal and foetal outcomes and safety of this practice. This systematic review aimed to summarise the effectiveness and safety of early initiation versus late initiation of epidural analgesia in women. We considered the obstetric and fetal outcomes relevant to women and side effects of the treatments, including risk of caesarean section, instrumental birth and time to birth. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (12 February 2014), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2014, Issue 1), MEDLINE (January 1966 to February 2014), Embase (January 1980 to February 2014) and reference lists of retrieved studies. We included all randomised controlled trials involving women undergoing epidural labour analgesia that compared early initiation versus late initiation of epidural labour analgesia. Two review authors independently assessed trials for inclusion, extracted the data and assessed the trial quality. Data were checked for accuracy. We included nine studies with a total of 15,752 women.The overall risk of bias of

A COMPARISON OF SPINAL ANAESTHESIA WITH LEVOBUPIVACAINE AND HYPERBARIC BUPIVACAINE COMBINED WITH FENTANYL IN CAESAREAN SECTION

Directory of Open Access Journals (Sweden)

Kurmanadh Kalepalli

2016-10-01

Full Text Available BACKGROUND Recent trends in obstetric anaesthesia show increased popularity of regional anaesthesia among obstetric anaesthetists. General anaesthesia in caesarean section is associated with high morbidity and mortality rate when compared with regional anaesthesia. Regional anaesthesia has its own demerits which are primarily related to excessively high spinal blocks and toxicity of local anaesthetics. Reduction in doses and improvement in technique to avoid high level blocks and increased awareness of toxicity of local anaesthetics have contributed to reduction in complications related to regional anaesthesia. The challenges presented by a parturient requiring anaesthesia or analgesia, or both, make the role of obstetric anaesthesiologist both challenging and rewarding. Spinal anesthesia is a popular technique for caesarean delivery. Hyperbaric Bupivacaine in 8% glucose is often used. Plain or glucose-free, Bupivacaine has been frequently referred to as “Isobaric” in the literature, even after Blomqvist and Nilsson demonstrated its hypobaricity. More recently, several studies have confirmed that plain Bupivacaine is indeed hypobaric in comparison with human CSF. Although hyperbaric local anesthetic solutions have a remarkable record of safety, their use is not totally without risk. To prevent unilateral or saddle blocks, patients should move from the lateral or sitting position rapidly to supine position. Hyperbaric solutions may cause sudden cardiac arrest after spinal anesthesia because of the extension of the sympathetic block. The use of truly isobaric solutions may prove less sensitive to position issues. Hyperbaric solutions may cause hypotension or bradycardia after mobilization. Isobaric solutions are favored with respect to their less sensitivity to postural changes. MATERIALS AND METHODS 60 full term parturients of ASA Grade 1 and 2 posted for elective caesarean section under spinal anaesthesia were divided in to two groups. GROUP

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

Full Text Available Dural ectasia is one of the likely causes of incomplete or failed spinal anaesthesia. Its association with diseases like Marfans syndrome, neurofibromatosis, osteogenesis imperfecta, vertebral fracture, postopertative adhesions, trauma etc., is often overlooked as a reason for inadequate spinal anaesthesia. Greater than normal volume of cerebrospinal fluid in the lumber theca in dural ectasia is postulated to restrict the spread of intrathecally injected Local anaesthetic. Here, we report a case of failed spinal anaesthesia but successful epidural anaesthesia in later setting in a patient with dural ectasia.

Attention to the application of vein anaesthesia in interventional radiology

2006-01-01

Interventional radiology is mostly carried out under local anesthesia with micro invasive characteristics. However, the questions of patient's pain, nerve intense, change of blood pressure and heart rate always influence the performance of operation. General anaesthesia in interventional radiology is a comparatively simple venous anaesthesia modality with a controlled dose of anesthetics injecting via periphery vein through persistent minimally injecting pump to keep the patient in dormancy under electrocardiographic monitoring. It doesn't require a tube insertion of trachea. The anaesthesia depth and time are under control. The half-life of the anaesthesia drugs is short with less side-effect. It is necessary to introduce the advanced anaesthesia into common interventional radiological therapy with attentions of promoting the development through new modalities. (authors)

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

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.

Local anaesthesia has been identified as the most favourable anaesthesia for elective inguinal hernia repair with respect to complication rate, cost effectiveness and overall patients' satisfaction. This study was conducted to determine the efficacy of local anaesthesia in inguinal hernia in terms of pain relief, wound infection and hospital stay. Methods: In this randomized controlled trial (RCT), 60 patients with inguinal hernia were included at the General Surgical 'B' Unit, Ayub Teaching Hospital Abbottabad. Results: The day-case rates were significantly higher when patients underwent surgery under LA compared to GA (82.6 percent versus 42.6 percent). The incidence of urinary retention was higher in the GA group (p<0.05). There were 17 (2.9 percent) re-admissions overall. The reasons for re-admission included haematoma (n=6), severe pain (n=4), infection (n=3), fainting (n=2) and urinary retention (n=2). Conclusion: This study demonstrates that local anaesthesia for inguinal hernia repair has better efficacy as compared to general anaesthesia. (author)

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

Meningitis following lumbar puncture and spinal anaesthesia is a rare but serious complication. A 19-year-old woman was administered spinal anaesthesia at another centre prior to a Caesarean section. The following day she experienced headaches. On the fourth day, she started vomiting and having convulsions, and became agitated. Meningitis was diagnosed based on a clinical examination and analysis of a lumbar puncture sample. After 21 days of treatment, she was discharged. Meningitis should be considered in the differential diagnosis of a patient presenting with headaches following spinal anaesthesia. The causes of meningitis following spinal anaesthesia are debated, and it is difficult to distinguish between aseptic and bacterial meningitis. It should be compulsory to wear a face mask while performing a dural puncture. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Erkin, Yüksel; Aydın, Zeynep; Taşdöğen, Aydın; Karcı, Ayşe

2013-01-01

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.

To provide stable anaesthesia of long duration in broiler chickens in order to perform a terminal caecal ligated loop procedure. Prospective experimental study. Seven clinically healthy broiler chickens (Gallus domesticus) aged 27-36 days, weighing 884-2000 g. Anaesthesia was induced and maintained with isoflurane in oxygen. All birds underwent intermittent positive pressure ventilation for the duration. End-tidal carbon dioxide, peripheral haemoglobin oxygen saturation, heart rate and oesophageal temperature were monitored continuously. All birds received intraosseous fluids. Butorphanol (2 mg kg(-1)) was administered intramuscularly at two hourly intervals. Euthanasia by parenteral pentobarbitone was performed at the end of procedure. Stable anaesthesia was maintained in four chickens for durations ranging from 435 to 510 minutes. One bird died and one was euthanized after 130 and 330 minutes, respectively, owing to surgical complications and another died from anaesthetic complication after 285 minutes. Long-term, stable anaesthesia is possible in clinically healthy chickens, provided complications such as hypothermia and hypoventilation are addressed and vital signs are carefully monitored. There are no known previous reports describing monitored, controlled anaesthesia of this duration in chickens. © 2015 The Authors Veterinary Anaesthesia and Analgesia published by John Wiley & Sons Ltd on behalf of Association of Veterinary Anaesthetists and the American College of Veterinary Anesthesia and Analgesia.

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

The advantages of patient-controlled epidural analgesia (PCEA) for delivery compared with continuous epidural analgesia (CEA) have been a point of interest in research obstetric anaesthesia for more than two decades. The aim of this single blind randomized controlled study was to evaluate the incidence of motor block and ability to perform partial knee flexion in women who received CEA or PCEA. Fifty-one healthy nulliparous women were included in this study. After an initial dose and established sensory block at Th 10, parturients were randomized into two groups: group CEA (10 ml/h), and group PCEA (bolus - 5 ml, lockout interval - 15 minutes, basal rate - 0 ml) with bupivacaine 0.08% and fentanyl 2 µg/ml. The motor function of the lower limbs was evaluated by modified Bromage scale at regular hourly intervals until full cervical dilatation. The quality of analgesia was assessed using a visual analogue pain scale (VAPS) and maternal satisfaction. Mode of delivery, the total number of additional rescue boluses, foetal and neonatal outcomes were recorded. Motor block was significantly lower in the third (33.3% vs. 4.35%; p = 0.008), fourth (57.9% vs. 6.3%; p = 0.003) and fifth hour (75.0% vs. 18.2%; p = 0.001) in the PCEA group. Ambulation occurred in 18% in the CEA and 46% in the PCEA group (p = 0.036). VAPS was with borderline significance in the second (p = 0.076) and significantly lower in the fourth hour (p = 0.034). Compared with CEA, PCEA provided less motor block and better first-stage analgesia, which leads to the conclusion that patient-controlled analgesia techniques are the preferred model in obstetric anesthesia.

Full Text Available This study aimed to determine the effect of intermittent positive pressure ventilation (IPPV on the depth of inhalation anaesthesia in parrots. Anaesthesia was induced with 3.0% isoflurane in six Sulphur-crested Cockatoos (Cacatua galerita galerita and maintained using either 1.5% or 3.0% during spontaneous ventilation (SV or IPPV at 6 (IPPV-6 or 12 (IPPV-12 breaths per minute. The time taken for the appearance of somatic reflexes and the return of SV after IPPV was recorded. During recovery, the body jerk, beak, eye, and shivering reflexes appeared after 126 ± 27 s, 133 ± 26 s, 165 ± 34 s, and 165 ± 44 s, respectively. All cockatoos developed apnoea after IPPV-12 and only some did after IPPV-6. Return of SV after IPPV-12 was delayed compared to IPPV-6. Recovery times after the SV runs were significantly different between 1.5% and 3.0% isoflurane anaesthesia. Similarly, after IPPV, the recovery times were significantly different between 1.5% and 3.0% isoflurane anaesthesia. Recovery times after 3.0% inhaled isoflurane were longer than those of 1.5% inhaled isoflurane. In conclusion, cockatoos recovering from isoflurane anaesthesia are likely to exhibit body jerk, beak, eye, and shivering reflexes in that order. IPPV increases the depth of anaesthesia in a rate and dose-related manner and prolongs recovery.

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

PurposeThis study was designed to investigate thoracic duct collateral leakage and the supply route of lymphatic fluid by lymphangiography and transcatheter thoracic ductography and to evaluate the results of embolization for thoracic duct collateral leakage performed to cut off this supply route.MethodsData were retrospectively collected from five patients who underwent embolization for thoracic duct collateral leakage in persistent high-output chylothorax after thoracic surgery. Extravasation of lipiodol at the ruptured thoracic duct collaterals was confirmed in all patients on lymphangiography. Transcatheter thoracic ductography was used to identify extravasation of iodinated contrast agent and to identify communication between the thoracic duct and leakage site. Thoracic duct embolization (TDE) was performed using the percutaneous transabdominal approach to cut off the supply route using N-butyl cyanoacrylate (NBCA) mixed with lipiodol (1:5–1:20).ResultsClinical success (drainage volume ≤10 mL/kg/day within 7 days after TDE) was achieved in all patients. The collateral routes developed as consequence of surgical thoracic duct ligation. In three patients, NBCA-Lipiodol reached the leakage site through direct communication between the thoracic duct and the ruptured lymphatic duct. In the other two patients, direct communication and extravasation was not detected on thoracic ductography, and NBCA-Lipiodol did not reach the leakage site. However, NBCA-Lipiodol did reach the cisterna chyli, lumbar trunks, and some collateral routes via the cisterna chyli or lumbar lymphatics. As a result, leakage was stopped.ConclusionsTDE was effective for the management of leakage of the collaterals in high-output chylothorax after thoracic surgery.

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

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.

The aim of this study is analysing the impact of the systematic versus occasional videoconferencing discussion of patients with two respiratory referral units along 6 years of time over the efficiency of the in-person outpatient clinics of a thoracic surgery service. Retrospective and comparative study of the evaluated patients through videoconferencing and in-person first visits during two equivalents periods of time: Group A (occasional discussion of cases) between 2008-2010 and Group B (weekly regular discussion) 2011-2013. Data were obtained from two prospective and electronic data bases. The number of cases discussed using e-consultation, in-person outpatient clinics evaluation and finally operated on under general anaesthesia in each period of time are presented. For efficiency criteria, the index: number of operated on cases/number of first visit outpatient clinic patients is created. Non-parametric Wilcoxon test is used for comparison. The mean number of patients evaluated at the outpatient clinics/year on group A was 563 versus 464 on group B. The median number of cases discussed using videoconferencing/year was 42 for group A versus 136 for group B. The mean number of operated cases/first visit at the outpatient clinics was 0.7 versus 0.87 in group B (P=.04). The systematic regular discussion of cases using videoconferencing has a positive impact on the efficacy of the outpatient clinics of a Thoracic Surgery Service measured in terms of operated cases/first outpatient clinics visit.

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

To 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.

Hemiparesis Caused by Cervical Spontaneous Spinal Epidural Hematoma: A Report of 3 Cases

Directory of Open Access Journals (Sweden)

Kinya Nakanishi

2011-01-01

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

The historical significance of anaesthesia events at Pearl Harbor.

Crowhurst, Ja

2014-07-01

Up to the end of World War II, less than 10% of the general anaesthetics administered was with intravenous barbiturates. The remaining 90% of anaesthetics given in the USA were with diethyl ether. In the United Kingdom and elsewhere, chloroform was also popular. Diethyl ether administration was a relatively safe and simple procedure, often delegated to nurses or junior doctors with little or no specific training in anaesthesia. During the Japanese attack on the US bases at Pearl Harbor, with reduced stocks of diethyl ether available, intravenous Sodium Pentothal(®), a most 'sophisticated and complex' drug, was used with devastating effects in many of those hypovolaemic, anaemic and septic patients. The hazards of spinal anaesthesia too were realised very quickly. These effects were compounded by the dearth of trained anaesthetists. This paper presents the significance of the anaesthesia tragedies at Pearl Harbor, and the discovery in the next few years of many other superior drugs that caused medical and other health professionals to realise that anaesthesia needed to be a specialist medical discipline in its own right. Specialist recognition, aided by the foundation of the National Health Service in the UK, the establishment of Faculties of Anaesthesia and appropriate training in pharmacology, physiology and other sciences soon followed. Modern anaesthesiology, as we understand it today, was born and a century or more of ether anaesthesia finally ceased.

Beginners in residency programmes in anaesthesia are challenged because working environment is complex, and they cannot rely on experience to meet challenges. During this early stage, residents need rules and structures to guide their actions and ensure patient safety. We investigated whether self-training with an electronic audiovisual checklist app on a mobile phone would produce a long-term improvement in the safety-relevant actions during induction of general anaesthesia. During the first month of their anaesthesia residency, we randomised 26 residents to the intervention and control groups. The study was performed between August 2013 and December 2014 in two university hospitals in Germany. In addition to normal training, the residents of the intervention group trained themselves on well tolerated induction using the electronic checklist for at least 60 consecutive general anaesthesia inductions. After an initial learning phase, all residents were observed during one induction of general anaesthesia. The primary outcome was the number of safety items completed during this anaesthesia induction. Secondary outcomes were similar observations 4 and 8 weeks later. Immediately, and 4 weeks after the first learning phase, residents in the intervention group completed a significantly greater number of safety checks than residents in the control group 2.8 [95% confidence interval (CI) 0.4 to 5.1, P = 0.021, Cohen's d = 0.47] and 3.7 (95% CI 1.3 to 6.1, P = 0.003, Cohen's d = 0.61), respectively. The difference between the groups had disappeared by 8 weeks: mean difference in the number of safety checks at 8 weeks was 0.4, 95% CI -2.0 to 2.8, P = 0.736, Cohen's d = 0.07). The use of an audiovisual self-training checklists improves safety-relevant behaviour in the early stages of a residency training programme in anaesthesia.

Another look at religious objections to obstetric anaesthesia.

Science.gov (United States)

McKenzie, A G

2016-08-01

Starting with the earliest biographies of James Young Simpson, the topic of religious opposition to obstetric anaesthesia in 1847 was gradually embellished in historical articles. Objective data are lacking and it has been suggested that this is a myth of recent medical history. A search for more information led to a contemporaneous case-book of the maternity hospital in Edinburgh, which was examined. The provision of anaesthesia in the 11months before publication of Simpson's pamphlet Answer to the Religious Objections was compared with that in the 11months after. This revealed a marked increase (P<0.01) in the provision of anaesthesia for childbirth after the publication of Simpson's pamphlet in December 1847. This analysis supports the existence of opposition to obstetric anaesthesia and the success of Simpson's pamphlet in overcoming it, but the introduction of chloroform about six weeks earlier, may also have contributed.

A case of thoracic myelopathy with alkaptonuria (ochronotic spondyloarthropathy) is presented. To present and review the first reported case of an alkaptonuric patient with concomitant thoracic myelopathy. Alkaptonuria, a rare hereditary metabolic disease, is characterized by accumulation of homogentistic acid, ochronosis, and destruction of connective tissue resulting in degenerative spondylosis and arthritis. Despite the high incidence of intervertebral disc diseases among patients with alkaptonuria, neurologic symptoms caused by spinal disease are rare. Thoracic myelopathy in a patient with alkaptonuria has not been previously reported. The clinical course, radiologic features, pathology, and treatment outcome of an alkaptonuria patient with thoracic myelopathy was documented. Myelopathy of the patient was caused by rupture of a thoracic intervertebral disc. The neurologic symptoms of the patient were markedly improved after surgery. We have reported for the first time, that an alkaptonuria patient showed thoracic myelopathy caused by rupture of a thoracic intervertebral disc. Decompression followed by the instrumented fusion of the thoracic spine was effective for improving the neurologic symptoms.

Marcelo Soares Privado

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

The database of incident forms relating to anaesthesia services in an institutional risk management programme were reviewed for 2003-2005, the aim being to identify any recurring patterns. Incidents were prospectively categorised as relating to attitude/behaviour, communication breakdown, delay in service, or were related to care, cost, environment, equipment, security, administrative process, quality of service or miscellaneous. The total number of anaesthesia-related incidents reported during the period was 287, which related to 0.44% of the total number of anaesthetics administered during the time period. In all, 170 incidents were reported by the department, 96 by internal customers and 21 by external customers. Only 30% of the complaints came from the operating room. Thirty-four per cent of all incidents related to communication, behaviour and delay in service. A requirement to teach communication skills and stress handling formally in anaesthesia training programmes, and at the time of induction of staff into the department, has been identified.

The German Social Act V section sign 12 is aimed towards competition, efficiency and quality in healthcare. Because surgical departments are billing standard diagnosis-related group (DRG) case costs to health insurance companies, they claim best value for money for internal services. Thus, anaesthesia concepts are being closely scrutinized. The present analysis was performed to gain economic arguments for the strategic positioning of regional anaesthesia procedures into clinical pathways. Surgical procedures, which in 2005 had a relevant caseload in Germany, were chosen in which regional anaesthesia procedures (alone or in combination with general anaesthesia) could routinely be used. The structure of costs and earnings for hospital services, split by types and centres of cost, as well as by underlying procedures are contained in the annually updated public accessible dataset (DRG browser) of the German Hospital Reimbursement Institute (InEK). For the year 2005 besides own data, national anaesthesia staffing costs are available from the German Society of Anaesthesiology (DGAI). The curve of earnings per DRG can be calculated from the 2005 InEK browser. This curve intersects by the cost curve at the point of national mean length of stay. The cost curve was calculated by process-oriented distribution of cost centres over the length of stay and allows benchmarking within the national competitive environment. For comparison of process times data from our local database were used. While the InEK browser lacks process times, the cost positions 5.1-5.3 (staffing costs anaesthesia) and the national structure adjusted anaesthesia staffing costs 2005 as published by the DGAI, were used to calculate nationwide mean available anaesthesia times which were compared with own process times. Within the portfolio diagram of lengths of stay for each DRG and process times most procedures are located in the economic lower left, in particular those with high case mix (length of stay and

MRI spectrum of findings in lumbosacral epidural lipomatosis

2004-01-01

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

Regional anaesthesia generally is considered to be safe. However, reports of complications with different severities are also well known. The scientific working group of regional anaesthesia of the DGAI has founded a network in conjunction with the BDA. With the aid of a registry, we are now able to describe risk profiles and associations in case of a complication. Moreover, a benchmark has been implemented in order to continuously improve complication rates. (c) Georg Thieme Verlag KG Stuttgart-New York.

The effect of 0.5% ropivacaine on epidural blood flow

Dahl, J B; Simonsen, L; Mogensen, T

1990-01-01

Twenty patients scheduled for elective abdominal surgery received epidural analgesia with 20 ml 0.5% ropivacaine or 0.5% bupivacaine. Epidural blood flow was measured by an epidural 133Xe clearance technique on the day before surgery (no local anaesthetic) and again 1 h before surgery, 30 min after...... injection of the local anaesthetic during continuous infusion (8 ml/h). Median initial blood flow was 5.0 ml/min and 6.0 ml/min per 100 g tissue in patients receiving ropivacaine and bupivacaine, respectively. After epidural bupivacaine, blood flow increased in 8 of 10 patients to 6.9 ml/min per 100 g...... tissue (P less than 0.05) in contrast to a decrease in 9 of 10 patients to 3.3 ml/min per 100 g tissue after ropivacaine (P less than 0.05), (P less than 0.01 between groups). The median level of sensory analgesia was T3.5 and T4.5 in the ropivacaine and bupivacaine group, respectively (P greater than 0...

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

Asystole Following Profound Vagal Stimulation During Hepatectomy

Preeta John

2008-01-01

Full Text Available Asystole in a non laparoscopic upper abdominal surgery following intense vagal stimulation is a rare event. This case report highlights the need for awareness of such a complication when a thoracic epidural anaesthetic has been given in addition to a general anaesthetic for an upper abdominal procedure. A combined thoracic epidural and general anaesthetic was given. The anterior abdominal wall was retracted forty minutes after administration of the epidural bolus. This maneuver resulted in a profound vagal response with bradycardia and asystole. The patient was resuscitated successfully with a cardiac massage, atropine and adrenaline and the surgery was resumed. Surgery lasted eleven hours and was uneventful.

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

2012-03-01

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

Intrathecal opioids versus epidural local anesthetics for labor analgesia: a meta-analysis.

Science.gov (United States)

Bucklin, Brenda A; Chestnut, David H; Hawkins, Joy L

2002-01-01

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.

2016-01-01

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

In thoracic surgery, the introduction of video-assisted thoracoscopic techniques has allowed the development of fast-track protocols, with shorter hospital lengths of stay and improved outcomes. The perioperative management needs to be optimized accordingly, with the goal of reducing postoperative complications and speeding recovery times. Premedication performed in the operative room should be wisely administered because often linked to late discharge from the post-anesthesia care unit (PACU). Inhalatory anesthesia, when possible, should be preferred based on protective effects on postoperative lung inflammation. Deep neuromuscular blockade should be pursued and carefully monitored, and an appropriate reversal administered before extubation. Management of one-lung ventilation (OLV) needs to be optimized to prevent not only intraoperative hypoxemia but also postoperative acute lung injury (ALI): protective ventilation strategies are therefore to be implemented. Locoregional techniques should be favored over intravenous analgesia: the thoracic epidural, the paravertebral block (PVB), the intercostal nerve block (ICNB), and the serratus anterior plane block (SAPB) are thoroughly reviewed and the most common dosages are reported. Fluid therapy needs to be administered critically, to avoid both overload and cardiovascular compromisation. All these practices are analyzed singularly with the aid of the most recent evidences aimed at the best patient care. Finally, a few notes on some of the latest trends in research are presented, such as non-intubated video-assisted thoracoscopic surgery (VATS) and intravenous lidocaine.

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

LENUS (Irish Health Repository)

Moran, Deirdre E

2012-09-01

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

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

This survey investigated the common practice of obstetric analgesia and anaesthesia in Swiss hospitals and evaluated the influence of the Swiss interest group for obstetric anaesthesia. In March 1999 we submitted 145 questionnaires to all Swiss hospitals providing an obstetric service. The rate of epidural analgesia (EA) was higher in large hospitals (> 1,000 births/year) than in small services. EA was maintained by continuous infusion techniques in 53% of the responding hospitals. For elective caesarean section, spinal anaesthesia (SA) and EA were performed in 77% and 16% of the patients, respectively. General anaesthesia (5%) was only used in small hospitals (interest group for obstetric anaesthesia, as well as the expectations of pregnant women, increased the numbers of regional anaesthesia compared with the first survey in 1992.

Spontaneous Cervical Epidural Hematoma with Hemiparesis Mimicking Cerebral Stroke

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

Full Text Available 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.

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.

Yamazaki, Y; Mimura, M; Hazama, K; Namiki, A

2000-04-25

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.

We conducted a prospective randomized study to evaluate whether the duration of action of a single bolus dose of rocuronium is influenced by maintenance of anaesthesia with sevoflurane, desflurane or propofol infusion. Fifty-seven ASA I-II patients undergoing elective abdominal surgery were enrolled in this study. Anaesthesia was induced with thiopental 3-5 mg kg(-1) or propofol 2.5 mg kg(-1) and fentanyl 5 microg kg(-1) and tracheal intubation was facilitated with rocuronium 0.9 mg kg(-1). Thereafter patients were randomly allocated to three different groups to receive sevoflurane, desflurane or propofol for maintenance of anaesthesia. Recovery of neuromuscular function was monitored by single twitch stimulation of the ulnar nerve and by recording the adductor pollicis response using accelerometry. Intergroup recovery times to 5% of control value of single twitch were analysed using analysis of variance with Bonferroni correction. The mean (95% confidence interval) recovery time to 5% of control value of single twitch during desflurane anaesthesia was 90.18 (86.11-94.25) min. Significantly shorter recovery times were observed during sevoflurane or propofol anaesthesia, 58.86 (54.73-62.99) min and 51.11 (45.47-56.74) min, respectively (P < 0.001). There were also significant differences in the recovery time between groups receiving desflurane vs. sevoflurane (P < 0.001) and desflurane vs. propofol (P < 0.001). Desflurane anaesthesia significantly prolongs the duration of action of rocuronium at 0.9 mg kg(-1) single bolus dose, compared to sevoflurane or propofol anaesthesia maintenance regimens.

Thoracic spine pain

Full Text Available Thoracic spine pain, or thoracalgia, is one of the common reasons for seeking for medical advice. The epidemiology and semiotics of pain in the thoracic spine unlike in those in the cervical and lumbar spine have not been inadequately studied. The causes of thoracic spine pain are varied: diseases of the cardiovascular, gastrointestinal, pulmonary, and renal systems, injuries to the musculoskeletal structures of the cervical and thoracic portions, which require a thorough differential diagnosis. Facet, costotransverse, and costovertebral joint injuries and myofascial syndrome are the most common causes of musculoskeletal (nonspecific pain in the thoracic spine. True radicular pain is rarely encountered. Traditionally, treatment for thoracalgia includes a combination of non-drug and drug therapies. The cyclooxygenase 2 inhibitor meloxicam (movalis may be the drug of choice in the treatment of musculoskeletal pain.

Epidural varix at the cervicothoracic junction: unusual cause of quadriplegia: a case report.

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

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.

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

We present our experience of transcutaneous truncal anaesthesia of the maxillary nerve in association with transmucosal anaesthesia of the sphenopalatine ganglion in surgically assisted rapid maxillary expansion. Twelve patients with a skeletal transverse discrepancy of the maxilla were treated in our department from 1994 to 1995. Maxillary transcutaneous nerve block was done with a Quincke 8 cm spinal needle together with transmucosal anaesthesia of the sphenopalatine ganglion. Mepivacaine without adrenaline and sodium bicarbonate 1/10 was used for truncal anaesthesia and lidocaine-prilocaine cream for transmucosal anaesthesia. A Le Fort I osteotomy, lateral nasal wall osteotomy, pterygomaxillary osteotomy, and a palatal osteotomy were done for all patients before the maxillary expansion. Total anaesthesia of the maxillary area facilitated the operations and appreciably reduced the amount of postoperative pain. The ease of achieving effective anaesthesia before and after operation and the absence of side-effects make this form of anaesthetic particularly useful in surgically assisted rapid maxillary expansion.

Full Text Available Abstract Background Many colic horses are compromised due to the disease state and from hours of starvation and sometimes long trailer rides. This could influence their muscle energy reserves and affect the horses' ability to recover. The principal aim was to follow metabolic parameter before, during, and up to 7 days after anaesthesia in healthy horses and in horses undergoing abdominal surgery due to colic. Methods 20 healthy horses given anaesthesia alone and 20 colic horses subjected to emergency abdominal surgery were anaesthetised for a mean of 228 minutes and 183 minutes respectively. Blood for analysis of haematology, electrolytes, cortisol, creatine kinase (CK, free fatty acids (FFA, glycerol, glucose and lactate was sampled before, during, and up to 7 days after anaesthesia. Arterial and venous blood gases were obtained before, during and up to 8 hours after recovery. Gluteal muscle biopsy specimens for biochemical analysis of muscle metabolites were obtained at start and end of anaesthesia and 1 h and 1 day after recovery. Results Plasma cortisol, FFA, glycerol, glucose, lactate and CK were elevated and serum phosphate and potassium were lower in colic horses before anaesthesia. Muscle adenosine triphosphate (ATP content was low in several colic horses. Anaesthesia and surgery resulted in a decrease in plasma FFA and glycerol in colic horses whereas levels increased in healthy horses. During anaesthesia muscle and plasma lactate and plasma phosphate increased in both groups. In the colic horses plasma lactate increased further after recovery. Plasma FFA and glycerol increased 8 h after standing in the colic horses. In both groups, plasma concentrations of CK increased and serum phosphate decreased post-anaesthesia. On Day 7 most parameters were not different between groups. Colic horses lost on average 8% of their initial weight. Eleven colic horses completed the study. Conclusion Colic horses entered anaesthesia with altered

Long-lasting increase in axonal excitability after epidurally applied DC.

Science.gov (United States)

Jankowska, Elzbieta; Kaczmarek, Dominik; Bolzoni, Francesco; Hammar, Ingela

2017-08-01

Effects of direct current (DC) on nerve fibers have primarily been investigated during or just after DC application. However, locally applied cathodal DC was recently demonstrated to increase the excitability of intraspinal preterminal axonal branches for >1 h. The aim of this study was therefore to investigate whether DC evokes a similarly long-lasting increase in the excitability of myelinated axons within the dorsal columns. The excitability of dorsal column fibers stimulated epidurally was monitored by recording compound action potentials in peripheral nerves in acute experiments in deeply anesthetized rats. The results show that 1 ) cathodal polarization (0.8-1.0 µA) results in a severalfold increase in the number of epidurally activated fibers and 2 ) the increase in the excitability appears within seconds, 3 ) lasts for >1 h, and 4 ) is activity independent, as it does not require fiber stimulation during the polarization. These features demonstrate an unexplored form of plasticity of myelinated fibers and indicate the conditions under which it develops. They also suggest that therapeutic effects of epidural stimulation may be significantly enhanced if it is combined with DC polarization. In particular, by using DC to increase the number of fibers activated by low-intensity epidural stimuli, the low clinical tolerance to higher stimulus intensities might be overcome. The activity independence of long-lasting DC effects would also allow the use of only brief periods of DC polarization preceding epidural stimulation to increase the effect. NEW & NOTEWORTHY The study indicates a new form of plasticity of myelinated fibers. The differences in time course of DC-evoked increases in the excitability of myelinated nerve fibers in the dorsal columns and in preterminal axonal branches suggest that distinct mechanisms are involved in them. The results show that combining epidural stimulation and transspinal DC polarization may dramatically improve their outcome and

Olfactory bulb encoding during learning under anaesthesia

Alister U Nicol

2014-06-01

Full Text Available Neural plasticity changes within the olfactory bulb are important for olfactory learning, although how neural encoding changes support new associations with specific odours and whether they can be investigated under anaesthesia, remain unclear. Using the social transmission of food preference olfactory learning paradigm in mice in conjunction with in vivo microdialysis sampling we have shown firstly that a learned preference for a scented food odour smelled on the breath of a demonstrator animal occurs under isofluorane anaesthesia. Furthermore, subsequent exposure to this cued odour under anaesthesia promotes the same pattern of increased release of glutamate and GABA in the olfactory bulb as previously found in conscious animals following olfactory learning, and evoked GABA release was positively correlated with the amount of scented food eaten. In a second experiment, multiarray (24 electrodes electrophysiological recordings were made from olfactory bulb mitral cells under isofluorane anaesthesia before, during and after a novel scented food odour was paired with carbon disulfide. Results showed significant increases in overall firing frequency to the cued-odour during and after learning and decreases in response to an uncued odour. Analysis of patterns of changes in individual neurons revealed that a substantial proportion (>50% of them significantly changed their response profiles during and after learning with most of those previously inhibited becoming excited. A large number of cells exhibiting no response to the odours prior to learning were either excited or inhibited afterwards. With the uncued odour many previously responsive cells became unresponsive or inhibited. Learning associated changes only occurred in the posterior part of the olfactory bulb. Thus olfactory learning under anaesthesia promotes extensive, but spatially distinct, changes in mitral cell networks to both cued and uncued odours as well as in evoked glutamate and

Patients are occasionally unhappy with the size, shape, and positioning of breast implants. An option to improve their satisfaction with breast augmentation includes directly involving them in the process with awake surgery done under nerve block and tumescence. This study describes the resultsof using such an awake anaesthesia technique in 35 patients. After the intercostal nerves dominating the Th3 to Th6 regions were anaesthetized using 0.5% bupivacaine, a tumescent solution consisting of lidocaine, epinephrine, and saline was injected around the mammary gland, and breast augmentation was conducted using silicon implants. The majority of patients (31/35) reported no pain during the procedure and all patients were able to choose and confirm their final implant size and positioning. In all cases, blood loss was less than 10 ml. No patient experienced pneumothorax or toxicity of local anaesthetics. Combined usage of the intercostal nerve block and tumescent anaesthesia effectively reduces pain during breast augmentation. Keeping patient conscious enables meeting their requests during operation, contributing to increased satisfaction. For these advantages, combined usage of the intercostal nerve block and tumescent anaesthesia is recommended as a useful anaesthetic technique for breast augmentation.

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

The effects of epidural analgesia on the course and outcome of labour.

Science.gov (United States)

Finster, M; Santos, A C

1998-09-01

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

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

Full Text Available A 10-year-old Thoroughbred mare was presented for lameness of the left hindlimb as a result of an apical fracture of the lateral proximal sesamoid bone. The mare was ultimately euthanased after suffering catastrophic fractures of the 3rd and 4th metatarsal bones of the contra-lateral hindlimb during an uncoordinated attempt to rise during recovery from general anaesthesia after undergoing arthroscopic surgery. The case report focuses mostly on horse anaesthesia-related mortality, anaesthetic procedure in the horse, possible causes of fractures in horses during recovery and ways in which rate of occurrence of these fractures can be minimised.

CONSERVATIVE THERAPY VERSUS EPIDURAL STEROID INFILTRATION IN MANAGEMENT OF CHRONIC LOW BACK ACHE

2015-11-01

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

Crisis management during anaesthesia: cardiac arrest.

Cardiac arrest attributable to anaesthesia occurs at the rate of between 0.5 and 1 case per 10 000 cases, tends to have a different profile to that of cardiac arrest occurring elsewhere, and has an in-hospital mortality of 20%. However, as individual practitioners encounter cardiac arrest rarely, the rapidity with which the diagnosis is made and the consistency of appropriate management varies considerably. To examine the role of a previously described core algorithm "COVER ABCD-A SWIFT CHECK", supplemented by a sub-algorithm for cardiac arrest, in the management of cardiac arrest occurring in association with anaesthesia. The potential performance of this structured approach for each the relevant incidents among the first 4000 reported to the Australian Incident Monitoring Study (AIMS) was compared with the actual management as reported by the anaesthetists involved. There were 129 reports of cardiac arrest associated with anaesthesia among the first 4000 AIMS incident reports. Identified aetiological factors were grouped into five categories: (1) anaesthetic technique (11 cases with this category alone; 32 with this and one or more of the other categories, representing 25% of all 129 cardiac arrests); (2) drug related (16; 32, 25%); (3) associated with surgical procedure (9; 29, 22%); (4) associated with pre-existing medical or surgical disease (30; 82, 64%); (5) unknown (8; 14, 11%). The "real life" presentation and management of cardiac arrest in association with anaesthesia differs substantially from that detailed in general published guidelines. Cardiac rhythms at the time were sinus bradycardia (23%); asystole (22%); tachycardia/ventricular tachycardia/ventricular fibrillation (14%); and normal (7%), with a further third unknown. Details of treatment were recorded in 110 reports; modalities employed included cardiac compression (72%); adrenaline (61%); 100% oxygen (58%); atropine (38%); intravenous fluids (25%), and electrical defibrillation (17%). There
