BACKGROUND: The current gold standard treatment for acute postoperative pain after major abdominal surgery is multimodal analgesia using patient controlled analgesia delivery systems. Patient controlled analgesia systems are expensive and their routine use in very low income countries is not practical. The use of ultrasound in anaesthesia has made some regional anaesthesia blocks technically easy and safe to perform. This study aimed to determine whether adding an ultrasound guided transversus abdominis plane block as an adjunct to the current parenteral opioid based regimen would result in superior pain relief after a trans abdominal hysterectomy compared to using parenteral opioids alone...

BACKGROUND: Surgery remains a mainstay of treatment for malignant tumours; however, surgical manipulation leads to a significant systemic release of tumour cells. Whether these cells lead to metastases is largely dependent on the balance between aggressiveness of the tumour cells and resilience of the body. Surgical stress per se, anaesthetic agents and administration of opioid analgesics perioperatively can compromise immune function and might shift the balance towards progression of minimal residual disease...

Surgical anaesthesia with haemodynamic stability and opioid-free analgesia in fragile patients can theoretically be provided with lumbosacral plexus blockade. We compared a novel ultrasound-guided suprasacral technique for blockade of the lumbar plexus and the lumbosacral trunk with ultrasound-guided blockade of the lumbar plexus. The objective was to investigate whether the suprasacral technique is equally effective for anaesthesia of the terminal lumbar plexus nerves compared with a lumbar plexus block, and more effective for anaesthesia of the lumbosacral trunk...

BACKGROUND: Spinal anesthesia is widely used for caesarean section due to its rapid onset, low failure rate, complete analgesia. Addition of intrathecal ketamine and opioids to local anaesthetics seems to improve the quality of block and prolong the duration of analgesia. OBJECTIVES: The purpose of this study was to compare the effect of intrathecal ketamine mixed with hyperbaric bupivacaine to intrathecal fentanyl mixed with hyperbaric bupivacaine. METHODS: One hundred parturients ASA Grade I scheduled for elective or semiurgent caesarean section under spinal anaesthesia were randomly divided into two groups...

OBJECTIVE: To measure the plasma concentrations of three endogenous opioid peptides and the levels of preproenkephalin (PPE) and preprodynorphin (PPD) mRNA in peripheral blood lymphocytes of patients during scheduled surgery performed under intravenous general anaesthesia combined with an epidural block. METHODS: Patients were anaesthetized and arterial blood was collected at 0 (baseline), 20, 40, 60, and 80 min during surgery. The plasma concentrations of β-endorphin, leucine-enkephalin and dynorphin A were measured using radioimmunoassay...

INTRODUCTION: Recent data suggest that using additional neuroaxial anaesthesia during oncological surgery is associated with favourable recurrence-free survival, when compared with general anaesthesia alone. We assessed the impact of adjunctive perioperative spinal anaesthesia and dose of opioids on the oncological long-term outcome of patients following radical prostatectomy. METHODS: We selected patients from our institutional review board-approved database who consecutively underwent radical prostatectomy between 2002 and 2007...

BACKGROUND: Patients undergoing bariatric surgery are at high risk of postoperative nausea and vomiting (PONV). Despite triple PONV prophylaxis, up to 42.7% of patients require antiemetic rescue medication (AERM). METHODS: This prospective, randomized study was conducted from November 2011 to October 2012. In the Classic group (n=59), patients underwent general anaesthesia with volatile anaesthetics and opioids. In the Total i.v. anaesthesia (TIVA) group (n=60), patients underwent opioid-free TIVA with propofol, ketamine, and dexmedetomidine...

REVIEW
Leopold Eberhart, Astrid Morin, Peter Kranke
Postoperative nausea and vomiting are undesirable and unpleasant side effects after surgery and anaesthesia associated with delayed oral intake and postoperative recovery, and impaired parental satisfaction. Since current modalities against PONV are cheap, highly effective, and almost free from relevant side-effects - providing contraindications are appropriately considered -, recommendations tend to move away from risk-score guided administration of antiemetic towards a more liberal administration policy or even favour routine administration to children undergoing general anaesthesia for surgery combined with total-intrevanous anaesthesia using propfol and reduction of perioperative opioid administration...

BACKGROUND: Intrathecal opioid administration yields high quality analgesia with an associated low incidence of side effects and complication. The benefits of spinal "opioid only technique" include absence of neuronal blockade, infusion pump malfunction and sympathetic blockade. This technique declined after serious side effects were reported in the 1990s. AIMS: To report on the safety and efficacy of the intrathecal catheter repeat bolus morphine technique for postoperative analgesia in patients having thoracotomy...

BACKGROUND: Electroacupuncture (EA) has been widely accepted and applied as an important acupuncture-related technique for acupuncture analgesia (AA) research. The involvement of opioid peptides and receptors in acute AA has been shown via pre-EA application of opioid receptor/peptide antagonists. In this study, we intended to reproducibly institute acupoint position and needling excluding influences from anaesthesia or restrainers on rats with complete Freund's adjuvant (CFA) hind paw inflammatory pain, as well as to explore opioid-dependency and anti-inflammatory effects in sustained acupuncture analgesia...

Our speciality commonly traces its origin to a demonstration of the inhalation of ether by a patient undergoing surgery in Boston in 1846. Less well known is the demonstration of the i.v. injection of opium with alcohol into a dog in Oxford in 1656, leading to anaesthesia followed by full long-term recovery. After gaining i.v. access, a mixture of opium and alcohol was injected, resulting in a brief period of anaesthesia. After a period during which the dog was kept moving to assist recovery, a full recovery was made...

Nitrous oxide is an antagonist at the N-methyl-D-aspartate receptor and may prevent the development of chronic postsurgical pain. We conducted a follow-up study in the Evaluation of Nitrous Oxide in the Gas Mixture for Anaesthesia (ENIGMA) trial patients to evaluate the preventive analgesic efficacy of nitrous oxide after major surgery. The ENIGMA trial was a randomized controlled trial of nitrous oxide-based or nitrous oxide-free general anesthesia in patients presenting for noncardiac surgery lasting more than 2 hours...

Nausea and vomiting are frequent complications of intrathecal morphine. In this randomised, double-blind trial, we tested the efficacy of mirtazapine, an antidepressant that blocks receptors associated with vomiting, on the incidence of nausea and vomiting after intrathecal morphine. One hundred patients receiving spinal anaesthesia for lower limb surgery were assigned equally to take either an orally disintegrating form of 30 mg mirtazapine or matching placebo 1 h before surgery. Spinal anaesthesia was performed by injection of 15 mg isobaric bupivacaine 0...

BACKGROUND: The transversus abdominis plane (TAP) block is a peripheral nerve block which anaesthetises the abdominal wall. The increasing use of TAP block, as a form of pain relief after abdominal surgery warrants evaluation of its effectiveness as an adjunctive technique to routine care and, when compared with other analgesic techniques. OBJECTIVES: To assess effects of TAP blocks (and variants) on postoperative analgesia requirements after abdominal surgery. SEARCH STRATEGY: We searched specialised registers of Cochrane Anaesthesia and Cochrane Pain, Palliative and Supportive Care Review Groups, CENTRAL, MEDLINE, EMBASE and CINAHL to June 2010...

In patients with aggressive tumors resistant to conventional pain treatment, regional anaesthesia frequently becomes an alternative therapy. Cervical paravertebral nerve block among several access options to the brachial plexus is barely ever used. We present a case with severe shoulder and upper extremity pain owing to an expanding Pancoast tumor exhibiting compression upon the brachial plexus. Continuous intrathecal morphine infusion and adjuvant treatment was not sufficient to render the patient pain-free...

BACKGROUND: The incidence of pruritus after elective caesarean section under spinal anaesthesia with subarachnoid morphine may be 60-100%, and is a common cause of maternal dissatisfaction. Ondansetron has been shown to reduce pruritus but the effect is short-lived. The objective of this randomized double-blind trial was to evaluate the anti-pruritic efficacy of granisetron compared with ondansetron. METHODS: Eighty ASA I or II women undergoing elective caesarean section received spinal anaesthesia with 0...

BACKGROUND: Activation of the serotonergic system is an important factor in the pathogenesis of intrathecal morphine-induced pruritus. Mirtazapine is a new antidepressant that selectively blocks 5-HT(2) and 5-HT(3) receptors. We therefore tested the hypothesis that preoperative mirtazapine would reduce the incidence of intrathecal morphine-induced pruritus. METHODS: One hundred and ten ASA I patients undergoing lower limb surgery under spinal anaesthesia were randomly allocated into two equal groups and received either mirtazapine 30 mg or an orally disintegrating placebo tablet 1 h before operation in a prospective, double-blinded trial...
