Regional anaesthesia for a Caesarean section in women with cardiac disease: a prospective study

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 1 2010
E. LANGESÆTER
Background We conducted a prospective observational survey of pregnant women with cardiac disease. The aim was to analyse and present the mode of delivery, outcome, and haemodynamic changes during a caesarean section under regional anaesthesia in women with cardiac disease. Methods All pregnant women with a cardiovascular diagnosis, except hypertension, were included in the registry. Based on the cardiac diagnoses, and on the New York Heart Association classification, a multidisciplinary group made recommendations for each patient and decided on the mode of delivery. The data from continuous, invasive haemodynamic monitoring in intermediate- and high-risk patients under regional anaesthesia for a caesarean section were analysed and presented. Results The hospital had approximately 9000 deliveries in the period from November 2003 to April 2008. A total of 113 pregnancies in 107 women were included. Thirty-two (28.3%) pregnancies were classified into the high-risk category. Of 103 deliveries, caesarean sections were performed in 59 (52.2%) cases, with regional anaesthesia in 51 patients (18 emergencies), general anaesthesia in eight patients (five emergencies), and a planned vaginal delivery in 44 patients. There was no mortality among the mothers or the babies during the hospital stay or 6 months postpartum. Pre-operative cardiovascular stability during the caesarean section was maintained by volume and phenylephrine infusion guided by invasive monitoring of haemodynamic variables. Conclusion Our study suggests that pregnant women with cardiac disease may safely deliver the baby by a caesarean section under regional anaesthesia. According to our findings, haemodynamic stability can be obtained by titrated regional anaesthesia, intravenous (i.v.) volume, phenylephrine infusion, and small repeated doses of i.v. oxytocin guided by invasive monitoring.

Anaesthesia and post-operative morbidity after elective groin hernia repair: a nation-wide study

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 2 2008
M. BAY-NIELSEN
Background: Randomised studies suggest regional anaesthesia to have the highest morbidity and local infiltration anaesthesia to have the lowest morbidity after groin hernia repair. However, implications and results of this evidence for general practice are not known. Methods: Prospective nation-wide data collection in a cohort of n=29,033 elective groin hernia repairs, registered in the Danish Hernia Database in three periods, namely July 1998,June 1999, July 2000,June 2001 and July 2002,June 2003. Retrospective analysis of complications in discharge abstracts, identified from re-admission within 30 days post-operatively, prolonged length of stay (>2 days post-operatively) or death. Results: Complications after groin hernia repair were more frequent in patients 65+ years (4.5%), compared with younger patients (2.7%) (P<0.001). In patients 65+ years, medical complications were more frequent after regional anaesthesia (1.17%), compared with general anaesthesia (0.59%) (P=0.003) and urological complications were more frequent after regional anaesthesia (0.87%), compared with local infiltration anaesthesia (0.09%) (P=0.006). Seventeen prostatectomies occurred after post-operative urinary retention, but with no case after local anaesthesia. Mortality within 30 days after elective groin hernia repair was 0.12%. Regional anaesthesia was disproportionately more often used in patients dying within 1 week post-operatively. Conclusion: Choice of the anaesthetic technique should be adjusted to available procedure-specific scientific evidence and the use of regional anaesthesia in elderly patients undergoing groin hernia repair is not supported by existing evidence.

New technologies in nerve location

ANAESTHESIA, Issue 2010
N. M. Bedforth
Summary Regional anaesthesia is undergoing a renaissance, perhaps assisted by the introduction of (and enthusiasm for) ultrasound-guided regional anaesthesia into clinical practice. This article summarises the technology and principles of ultrasound imaging in anaesthesia and describes the development of three-dimensional ultrasound imaging, considering whether this new technology has an application in regional anaesthesia.

Regional anaesthesia and pain management

ANAESTHESIA, Issue 2010
I. Power
Summary Despite recent advances in analgesia delivery techniques and the availability of new analgesic agents with favourable pharmacokinetic profiles, current evidence suggests that postoperative pain continues to be inadequately managed, with the proportion of patients reporting severe or extreme postoperative pain having changed little over the past decade. Regional techniques are superior to systemic opioid agents with regards to analgesia profile and adverse effects in the context of general, thoracic, gynaecological, orthopaedic and laparoscopic surgery. Outcome studies demonstrate that regional analgesic techniques also reduce multisystem co-morbidity and mortality following major surgery in high risk patients. This review will discuss the efficacy of regional anaesthetic techniques for acute postoperative analgesia, the impact of regional block techniques on physiological outcomes, and the implications of acute peri-operative regional anaesthesia on chronic (persistent) postoperative pain.

Regional anaesthesia in day-stay and short-stay surgery

ANAESTHESIA, Issue 2010
S. L. Kopp
Summary The goals for ambulatory surgery are rapid recovery with minimal side effects, adequate postoperative pain control, rapid patient discharge and overall cost containment. The addition of regional anaesthetic techniques has been shown to decrease nausea, postoperative pain scores and the need for post-anaesthesia care unit monitoring. The use of regional anaesthesia is increasing as studies confirm the goals for ambulatory anaesthesia can be met with a combination of regional anaesthesia and a multimodal pain management regimen.

Current trends in paediatric regional anaesthesia

ANAESTHESIA, Issue 2010
H. Willschke
Summary Regional anaesthesia is a cornerstone in paediatric anaesthesia today. Many paediatric anaesthetists include regional anaesthetic techniques in their daily clinical practice to provide superior and long-lasting analgesia without the risk of respiratory depression. The first part this article reviews new scientific findings in the field of paediatric regional anaesthesia. The second part focuses on safety aspects and on the impact of ultrasound on paediatric regional anaesthesia. [source]

Complications of regional anaesthesia

ANAESTHESIA, Issue 2010
J. Picard
Summary Regional anaesthesia can marvellously dull the pain (and limit some other complications) of trauma, surgery and childbirth. But like all powerful techniques, it may have complications. Here the complications of regional anaesthesia are reviewed. The risks, presentation and the management of these complications are discussed in turn. [source]

Anaesthesia for proximal femoral fracture in the UK: first report from the NHS Hip Fracture Anaesthesia Network,

ANAESTHESIA, Issue 3 2010
S. M. White
Summary The aim of this audit was to investigate process, personnel and anaesthetic factors in relation to mortality among patients with proximal femoral fractures. A questionnaire was used to record standardised data about 1195 patients with proximal femoral fracture admitted to 22 hospitals contributing to the Hip Fracture Anaesthesia Network over a 2-month winter period. Patients were demographically similar between hospitals (mean age 81 years, 73% female, median ASA grade 3). However, there was wide variation in time from admission to operation (24,108 h) and 30-day postoperative mortality (2,25%). Fifty percent of hospitals had a mean admission to operation time < 48 h. Forty-two percent of operations were delayed: 51% for organisational; 44% for medical; and 4% for ,anaesthetic' reasons. Regional anaesthesia was administered to 49% of patients (by hospital, range = 0,82%), 51% received general anaesthesia and 19% of patients received peripheral nerve blockade. Consultants administered 61% of anaesthetics (17,100%). Wide national variations in current management of patients sustaining proximal femoral fracture reflect a lack of research evidence on which to base best practice guidance. Collaborative audits such as this provide a robust method of collecting such evidence. [source]

Regional anaesthesia for limb surgery: a review of anaesthetists' beliefs and practice in the Oxford region*

ANAESTHESIA, Issue 6 2008
N. M. Feely
Summary We conducted a postal survey of 210 anaesthetists in the Oxford region to determine their views and practice regarding the timing of regional anaesthesia when combined with general anaesthesia for adults undergoing limb surgery and to compare the results with those obtained in a similar survey conducted in 2001. Of the 151 respondents (72% response rate), 102 (68%) regularly combined regional and general anaesthesia for adult limb surgery. Over 80% believed that central neuraxial blocks should be performed before general anaesthesia. This matched their current practice, marking a change from 2001. Significantly fewer anaesthetists believed it necessary to perform peripheral nerve blocks before general anaesthesia than in 2001, marking another significant change in practice. Overall, the results indicate an increased popularity of regional blocks in combination with general anaesthesia when compared with 2001 practice, which we believe is related to high quality advanced training modules now on offer to senior trainees in the Oxford region.

Regional anaesthesia in developing countries

ANAESTHESIA, Issue 2007
T. Schnittger
Summary In modern anaesthesia practice, regional techniques are preferred to general anaesthesia for many types of surgery, particularly in obstetric care. Improved outcomes have been recorded in UK practice, but the techniques remain underutilised in many parts of the world. With encouragement, training and a regular supply of appropriate needles and local anaesthetic agents, the advantages of regional techniques in the developing world could be realised. [source]

Regional anaesthesia and propofol sedation for carotid endarterectomy

ANZ JOURNAL OF SURGERY, Issue 7 2005
Christopher Barringer
Background: Many surgeons now perform carotid endarterectomy under regional anaesthesia. The aim of the present study was to review a sedation technique using a computer-controlled infusion of propofol. Methods: A consecutive series of 84 carotid endarterectomies done by a single surgeon and commenced under regional anaesthesia with sedation was studied. There were 54 men and 27 women (three bilateral procedures), with a median age of 71 years (range 48,87 years). All patients had carotid stenosis >70% 80 procedures were done for symptomatic disease and three asymptomatic patients were treated before cardiac surgery (one bilateral). Results: Seventy-seven procedures were completed under regional anaesthesia and sedation alone; seven required conversion to general anaesthetic, usually for intolerance of the operation. An intraoperative shunt was required on only four occasions (5%). Postoperatively eight patients required critical care monitoring, usually for blood pressure control. The remainder were nursed on the vascular ward, and 68% were discharged home on the day after surgery. No patient died, but there were two neurological complications. One patient had a cerebellar stroke 10 days after surgery, but recovered fully after 4 months. A second developed cerebral oedema due to severe intraoperative hypertension and required intensive care for 15 days. He too recovered fully. Five patients had a further episode of transient cerebral ischaemia within 1 month of operation, but in all cases duplex imaging showed a widely patent carotid and there were no sequelae. Conclusion: Target controlled propofol infusion is an effective method of sedation in patients undergoing carotid endarterectomy. [source]

Effect of epidural dexmedetomidine on intraoperative awareness and post-operative pain after one-lung ventilation

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 6 2010
M. ELHAKIM
Background: During combined general and regional anaesthesia, it is difficult to use autonomic signs to assess whether wakefulness is suppressed adequately. We compared the effects of a dexmedetomidine,bupivacaine mixture with plain bupivacaine for thoracic epidural anaesthesia on intraoperative awareness and analgesic benefits, when combined with superficial isoflurane anaesthesia (<0.05 maximum alveolar concentration) in patients undergoing thoracic surgery with one-lung ventilation (OLV). Methods: Fifty adult male patients were randomly assigned to receive either epidural dexmedetomidine 1 ,g/kg with bupivacaine 0.5% (group D) or bupivacaine 0.5% alone (group B) after induction of general anaesthesia. Gasometric, haemodynamic and bispectral index values were recorded. Post-operative verbal rating score for pain and observer's assessment of alertness/sedation scale were determined by a blinded observer. Results: Dexmedetomidine reduced the use of supplementary fentanyl during surgery. Patients in group B consumed more analgesics and had higher pain scores after operation than patients of group D. The level of sedation was similar between the two groups in the ICU. Two patients (8%) in group B reported possible intraoperative awareness. There was a limited decrease in PaO2 at OLV in group D compared with group B (P<0.05). Conclusion: In thoracic surgery with OLV, the use of epidural dexmedetomidine decreases the anaesthetic requirements significantly, prevents awareness during anaesthesia and improves intraoperative oxygenation and post-operative analgesia.

Systematic evaluation of the highest current threshold for regional anaesthesia in a porcine model

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 6 2010
T. STEINFELDT
Background: The purpose of this study was to determine systematically the highest minimal stimulation current threshold for regional anaesthesia in pigs. Methods: In an established pig model for regional anaesthesia, needle placements applying electric nerve stimulation were performed. The primary outcome was the frequency of close needle to nerve placements as assessed by resin injectates and subsequent anatomical evaluation. Following a statistical model (continual reassessment method), the applied output currents were selected to limit the necessary number of punctures, while providing guidance towards the highest output current range. Results: Altogether 186 punctures were performed in 11 pigs. Within the range of 0.3,1.4 mA, no distant needle to nerve placement was found. In the range of 1.5,4.1 mA, 43 distant needle to nerve placements occurred. The range of 1.2,1.4 mA was the highest interval that resulted in a close needle to nerve placement rate of ,95%. Conclusions: In the range of 0.3,1.4 mA, all resin deposition was found to be adjacent to nerve epineurium. The application of minimal current intensities up to 1.4 mA does not obviously lead to a reduction of epineural injectate contacts in pigs. These findings suggest that stimulation current thresholds up to 1.4 mA result in equivalent needle tip localisation in pigs. [source]

Chronic, painful lower extremity wounds: postoperative pain management through the use of continuous infusion of regional anaesthesia supplied by a portable pump device

INTERNATIONAL WOUND JOURNAL, Issue 3 2010
Christy L Scimeca
Reducing and preventing postoperative pain are currently a topic of great interest. There are different modalities for providing analgesia that can provide an alternative or adjunct to opioid therapy. One mode of therapy involves the use of portable pain pump devices that can deliver continuous local anaesthesia directly to the site of interest. A considerable amount of attention in literature has been dedicated to using regional anaesthesia postoperatively for various surgical applications. However, to our knowledge, little or no work has been published concerning the use of infusion of regional anaesthesia in the treatment of painful lower extremity wounds. We present a case report of a 55-year-old gentleman with a complex past medical history, 2-year history of opioid dependency and a 2-week history of intractable pain associated with the combination of debilitating painful diabetic neuropathy and painful lower extremity wounds. After surgical debridement of the lower extremity wounds, substantial analgesia was achieved postoperatively through the implantation of a portable direct infusion pump device. The device supplied 2 ml/hour of 0·25% bupivacaine and resulted in a reduction in pain within the first hour of implantation. Although the device achieved maximal analgesia at 6 hours, we found that this could have been likely reduced through the use of a 5-ml bolus dose of 0·25% bupivacaine at the time of implantation. The device provided sufficient analgesia to the patient without any observed adverse effects, and showed significant potential in avoiding an increase in his requirement for other systemic analgesia including opioids.

Regional anaesthesia for a Caesarean section in women with cardiac disease: a prospective study

High or low current threshold for nerve stimulation for regional anaesthesia

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 10 2009
T. STEINFELDT
Background: The purpose of this study was to determine whether the application of high stimulation current thresholds (SCT) leads to a distant needle to nerve proximity (NNP) compared with low SCT during nerve localization for regional anaesthesia in pigs. Methods: A minimal motor response to the stimulation of femoral or brachial plexus nerves in 16 anaesthetized pigs was triggered either by a minimal SCT of a low (0.01,0.3 mA) or a high (0.8,1.0 mA) current in a random order. After eliciting a motor response with a predetermined SCT, synthetic resin was injected via the needle. After postmortem dissection of the injection site, the localization of the resin deposition was determined verifying the final position of the needle tip. Depending on the proximity of resin deposition to the nerve epineurium, the needle tip placement was considered either as a close or a distant NNP. Results: A total of 235 punctures were performed. Ninety-one punctures were carried out with low SCT and 92 with a high SCT. Fifty-two punctures served as a control (1.8,2.0 mA). All injectates following both high or low SCT were considered ,close needle tip to nerve placement', whereas 27 of 52 injectates of the control group appeared distant to nerve epineurium. Conclusion: Regardless of the applied SCT, i.e. high or low, all resin deposition was found adjacent to nerve epineurium. These findings suggest that high and low SCT result in equivalent needle tip localization in pigs. [source]

A Survey of the Current Practice of Obstetric Anaesthesia and Analgesia in Malaysis

JOURNAL OF OBSTETRICS AND GYNAECOLOGY RESEARCH (ELECTRONIC), Issue 2 2000
Dr. Y. K. Chan
Abstract Objective: A survey covering 30% of the deliveries in Malaysia was done to determine the practice of obstetric anaesthesia and analgesia for 1996. Results: From the survey, it was found that the regional anaesthesia rate for caesarean section was 46% in the government hospitals compared to 29.2% in the private hospitals, with spinal anaesthesia being the most common regional anaesthetic technique used in both types of hospitals. The epidural rate for labour analgesia was only 1.5% overall for the country. Epidural analgesia services were available in all private hospitals whereas 17.6% of government hospitals surveyed did not offer this service at all. Conclusions: Although the use of epidural analgesia for labour was low in Malaysia, the overall rate of regional anaesthesia for caesarean section (41.9%) is very much in keeping with the standards of safe practice recommended by the United Kingdom.

Anaesthesia and post-operative morbidity after elective groin hernia repair: a nation-wide study

Is peri-operative cortisol secretion related to post-operative cognitive dysfunction?

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 9 2005
L. S. Rasmussen
Background:, The pattern of cortisol secretion is influenced by surgery. As cortisol can adversely affect neuronal function, this may be an important factor in the development of post-operative cognitive dysfunction (POCD). We hypothesized that the incidence of POCD would be related to changes in cortisol level. Methods:, We studied 187 patients aged over 60 years undergoing major non-cardiac surgery with general or regional anaesthesia. Saliva cortisol levels were measured pre-operatively and at 1 day, 7 days and 3 months post-operatively in the morning (08.00 h) and in the afternoon (16.00 h) using salivettes. Cognitive function was assessed pre-operatively, on day 7 and at 3 months using four neuropsychological tests. POCD was defined as a combined Z score of greater than 1.96. Results:, After surgery, salivary cortisol concentrations increased significantly. POCD was detected in 18.8% of subjects at 1 week and in 15.2% after 3 months. The pre-operative ratios between the morning and afternoon cortisol concentrations (am/pm ratios) were 2.8 and 2.7 in patients with POCD at 1 week vs. those without POCD at 1 week, respectively. The am/pm ratios decreased significantly post-operatively to 1.9 and 1.6 at 1 week, respectively (P = 0.02 for both). In an analysis considering all am/pm ratios, it was found that the persistent flattening in am/pm ratio was significantly related to POCD at 1 week. Conclusion:, The pattern of diurnal variation in cortisol level was significantly related to POCD. Thus, circadian rhythm disturbance or metabolic endocrine stress could be an important mechanism in the development of cognitive dysfunction after major surgery. [source]

Incidence of postoperative nausea and vomitingin paediatric ambulatory surgery

PEDIATRIC ANESTHESIA, Issue 8 2002
I. Villeret
SummaryBackground: We performed a prospective descriptive study over a 5-month period to determine the incidence of postoperative nausea and vomiting (PONV) during the first 24 h following elective ambulatory paediatric surgery, excluding head and neck procedures. Methods: Four hundred and seven patients, aged 15 days to 16 years, were analysed prospectively. Results: The incidence of PONV was 9.4%, occurring most frequently during the first 3 h after anaesthesia and in hospital but rarely during the journey home. It was associated with age, previous history of PONV, tracheal intubation or use of the laryngeal mask airway (LMAÔ), controlled or manual ventilation, opioids and absence of oral intake of liquids or solids. Conversely, type of surgery, premedication, induction mode, association of regional anaesthesia, inhaled nitrous oxide, duration of anaesthesia, stay in the postanaesthesia care unit and duration of journey after discharge were not significantly associated with PONV. Conclusions: PONV never induced complications or delayed patient discharge and curative treatment was rapidly effective. [source]

Litigation related to regional anaesthesia: an analysis of claims against the NHS in England 1995,2007,

ANAESTHESIA, Issue 5 2010
K. Szypula
Summary We analysed 366 claims related to regional anaesthesia and analgesia from the 841 anaesthesia-related claims handled by the National Health Service Litigation Authority between 1995 and 2007. The majority of claims (281/366, 77%) were closed at the time of analysis. The total cost of closed claims was £12 724 017 (34% of the cost of the anaesthesia dataset) with a median (IQR [range]) of £4772 (£0,28 907 [£0,2 070 092]). Approximately half of the claims (186/366; 51%) were related to obstetric anaesthesia and analgesia and of the non-obstetric claims, the majority (148/180; 82%) were related to neuraxial block. The total cost for obstetric closed claims was £5 433 920 (median (IQR [range]) £5678 (£0,27 690 [£0,1 597 565]) while that for non-obstetric closed claims was £7 290 097 (£3337 (£0,31 405 [£0,2 070 062]). Non-obstetric claims were more likely to relate to severe outcomes than obstetric ones. The maximum values of claims were higher for claims related to neuraxial blocks and eye blocks than for peripheral nerve blocks. Despite many limitations, including lack of clinical detail for each case, the dataset provides a useful overview of the extent, patterns and cost associated with the claims. [source]

Ultrasound in regional anaesthesia

ANAESTHESIA, Issue 2010
J. Griffin
Summary Ultrasound guidance is rapidly becoming the gold standard for regional anaesthesia. There is an ever growing weight of evidence, matched with improving technology, to show that the use of ultrasound has significant benefits over conventional techniques, such as nerve stimulation and loss of resistance. The improved safety and efficacy that ultrasound brings to regional anaesthesia will help promote its use and realise the benefits that regional anaesthesia has over general anaesthesia, such as decreased morbidity and mortality, superior postoperative analgesia, cost-effectiveness, decreased postoperative complications and an improved postoperative course. In this review we consider the evidence behind the improved safety and efficacy of ultrasound-guided regional anaesthesia, before discussing its use in pain medicine, paediatrics and in the facilitation of neuraxial blockade. The Achilles' heel of ultrasound-guided regional anaesthesia is that anaesthetists are far more familiar with providing general anaesthesia, which in most cases requires skills that are achieved faster and more reliably. To this ends we go on to provide practical advice on ultrasound-guided techniques and the introduction of ultrasound into a department. [source]
