Randomized Controlled Trial Comparative Study Clinical TrialLumbar versus thoracic epidural buprenorphine for postoperative analgesia following coronary artery bypass graft surgery.
Thoracic epidural analgesia (TEA) is reported to provide effective analgesia following cardiac surgery. We compared the effect of buprenorphine (BN) through the lumbar and thoracic epidural routes for postoperative analgesia following coronary artery bypass graft surgery (CABG). ⋯ This study shows that BN by the lumbar epidural route for analgesia after CABG compares favourably with the same drug through the thoracic route in terms of quality of analgesia and incidence of side effects.

Case ReportsCauda equina syndrome after spinal anaesthesia with hyperbaric 5% lignocaine: a review of six cases of cauda equina syndrome reported to the Swedish Pharmaceutical Insurance 1993-1997.
Six cases of cauda equina syndrome with varying severity were reported to the Swedish Pharmaceutical Insurance during the period 1993-1997. All were associated with spinal anaesthesia using hyperbaric 5% lignocaine. Five cases had single-shot spinal anaesthesia and one had a repeat spinal anaesthetic due to inadequate block. ⋯ In the other 3 cases, direct neurotoxicity was also probable, but unfortunately radiological investigations were not done to definitely exclude a compressive aetiology. All cases sustained permanent neurological deficits. We recommend that hyperbaric lignocaine should be administered in concentrations not greater than 2% and at a total dose preferably not exceeding 60 mg.

Case ReportsPercutaneous dilatational tracheostomy in a patient with thyroid cancer and severe airway obstruction.
A patient with extensive metastatic thyroid cancer scheduled for palliative tracheostomy is presented. He had laryngeal dislocation with severe airway obstruction and few anatomical landmarks due to tumour infiltration and radiation. Successful percutaneous dilatational tracheostomy was performed under local anaesthesia.

Randomized Controlled Trial Comparative Study Clinical TrialIrrigation fluid absorption during transurethral resection of the prostate: spinal vs. general anaesthesia.
The absorption of irrigation fluid during transurethral resection of the prostate (TURP) is determined primarily by hydrostatic pressure in the bladder and prostatic venous pressure. In comparison to spontaneously breathing patients, patients undergoing mechanical ventilation with positive pressure have a raised central venous pressure and a reduced venous return, both of which can influence intravascular absorption. The purpose of the prospective study was to compare the effects of general (GA) and spinal anaesthetic (SA) techniques on the perioperative absorption of irrigating fluid in patients undergoing TURP. ⋯ The absorption of irrigation fluid during the TURP is significantly more marked amongst spontaneously breathing patients with regional anaesthesia in comparison to patients undergoing general anaesthesia with positive pressure ventilation. The markedly lower central venous pressure before the start of irrigation should be considered as a possible cause of this effect.

Randomized Controlled Trial Clinical TrialThe sevoflurane-sparing effect of nitrous oxide: a clinical study.
We studied the sevoflurane-sparing effect of nitrous oxide in a prospective randomised study. ⋯ Nitrous oxide was found to be cost-effective for use during short ambulatory knee arthroscopy.
