Meta AnalysisA meta-analysis on the efficacy of epidural corticosteroids in the treatment of sciatica.
The efficacy of epidural corticosteroids in the treatment of sciatica was investigated by meta-analysis of all randomized controlled trials. Eleven suitable trials of good quality were identified involving a total of 907 patients. The use of epidural (caudal or lumbar) steroid in the short-term (up to 60 days) increased the odds ratio (OR) of pain relief ( > 75% improvement) to 2.61 (95% CI 1.90-3.77) when compared with placebo. ⋯ Adverse events included dural tap (2.5%), transient headache (2.3%) and a transient increase in pain (1.9%). There were no reported longterm adverse events. In conclusion we present quantitative evidence from meta-analysis of pooled data from randomized trials that epidural administration of corticosteroids is effective in the management of lumbosacral radicular pain.

A prospective analysis of placement of left-sided plastic double-lumen tubes in 100 patients is presented. Intubation of the left bronchus was successfully accomplished using only auscultation and clinical signs ("blind" placement) in 91 patients. Double-lumen tubes were positioned in less than five minutes in 84 patients. ⋯ Seven of these patients required bronchoscopic assistance to guide the tube into the left bronchus. There were four minor intraoperative complications due to DLT malposition that were recognized and corrected by withdrawing the tube slightly back in the bronchus. The plastic double-lumen tubes functioned properly during the procedure in all 100 patients.

Randomized Controlled Trial Clinical TrialEffect of propofol infusion on the endocrine response to cardiac surgery.
The effect of propofol infusion on the stress response was studied in patients undergoing coronary artery bypass graft (CABG). Ten patients received propofol infusion during cardiopulmonary bypass (CPB) and ten controls received diazepam. ⋯ There was a significant reduction in all three hormones (P < 0.05) in the study group. In addition, the amount of sodium nitroprusside used during CPB was significantly reduced (P < 0.05).
