Randomized Controlled Trial Clinical Trial
North American survey of the management of dural puncture occurring during labour epidural analgesia.
To document the range and the most common strategies for the management of the parturient with inadvertent dural puncture (DP) during labour epidural analgesia. ⋯ There is little difference between the practices reported by Canadian or US centres. The expressed optimism regarding the efficacy of EBP is not supported by the evidence available and may be unwarranted. More research is needed to define the issue better.

Randomized Controlled Trial Clinical Trial
Prevention of PONV with granisetron, droperidol or metoclopramide in patients with postoperative emesis.
A high incidence of postoperative nausea and vomiting (PONV) has been noted in patients with a history of postoperative emesis. This study was undertaken to compare the efficacy of granisetron, droperidol and metoclopramide, in the prevention of PONV in such patients undergoing general anaesthesia for major gynaecological surgery. ⋯ Granisetron is more effective than droperidol or metoclopramide in preventing PONV in female patients with a history of postoperative emesis.

Randomized Controlled Trial Comparative Study Clinical Trial
Cardiac output during liver transplantation.
Measurement of cardiac output is an essential part of anaesthetic practice in patients undergoing major operative procedures. A thermodilution technique, using a pulmonary artery catheter is currently accepted as the gold standard in clinical practice. However its use is associated with several limitations. ⋯ The use of the ODM results in cardiac output measurements which are considerably different from those obtained using thermodilution and its use cannot be recommended in patients undergoing orthotopic liver transplantation.

Randomized Controlled Trial Clinical Trial
Minimum effective anaesthetic concentration of hyperbaric lidocaine for spinal anaesthesia.
Minimum effective anaesthetic concentration (MEAC) of lidocaine for spinal anaesthesia, defined as the concentration at which a spinal anaesthetic agent produces surgical anaesthesia within 20 min of administration in 50% of patients, was determined in a randomised, double-blind study in young patients undergoing knee and ankle surgery. ⋯ Spinal anaesthesia can be accomplished with very dilute lidocaine solutions (< 0.9%). The value of MEAC is dose-dependent, i.e., complete anaesthesia can be accomplished with lower concentrations by increasing the dose of spinal anaesthetic administered.

Randomized Controlled Trial Clinical Trial
Epidural ketamine reduces post-operative epidural PCA consumption of fentanyl/bupivacaine.
To study the analgesic effect of epidural ketamine on postoperative pain and epidural PCA consumption after total abdominal hysterectomy. ⋯ Epidural ketamine 30 mg reduces post hysterectomy pain as evidenced by prolongation of time to first analgesia request and reduction in postoperative epidural PCA consumption. This effect is manifest whether ketamine is given before induction or 20 min after skin incision.
