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.

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).

The perioperative system: a new approach to managing elective surgery.
A Perioperative Service has recently been introduced at liverpool hospital, a 460-bed university teaching hospital. This provides a co-ordinated system for managing all elective surgical patients from the time an admission booked until hospital discharge. This paper describes the patient assessment, structure and staff requirements, benefits of and problems encountered with this service. ⋯ There has been a reduction in the areas of cancellations due to unavailability of beds, inappropriate preparation of patients, and non-attendance of patients for booked procedures. Patient acceptance is high. The existence of a perioperative system facilitates the planning and management of elective surgery with maximum quality and efficiency.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of total intravenous, balanced inhalational and combined intravenous-inhalational anaesthesia for tympanoplasty, septorhinoplasty and adenotonsillectomy.
Two hundred and thirty-five consecutive Saudi patients aged between two and fifty-three years undergoing elective tympanoplasty (n = 32), septorhinoplasty (n = 68) or adenotonsillectomy (n = 135) were studied. They were randomized to receive either a total intravenous anaesthetic (10 ears, 23 noses, 44 throats) consisting of propofol for induction of anaesthesia followed by a propofol infusion, a combined intravenous-inhalational anaesthetic (11 ears, 22 noses, 46 throats) consisting of the above with isoflurane in oxygen-enriched air, or a balanced inhalational anaesthetic (11 ears, 23 noses, 45 throats) consisting of thiopentone for induction of anaesthesia and oxygen in nitrous oxide with isoflurane for maintenance. During tympanoplasty, all three anaesthetic techniques produced stable heart rates and arterial pressures. ⋯ During adenotonsillectomy, total intravenous anaesthesia produced a rise in both heart rate and blood pressure, the combined technique produced a rise in heart rate alone while balanced anaesthesia produced haemodynamic stability. Postoperatively, vomiting, pain scores and analgesic requirements were similar following all three types of anaesthetic within each surgical site subgroup. Our findings support the choice of balanced inhalational anaesthesia for all three types of ENT surgery and, where cost and facilities permit, total intravenous anaesthesia for tympanoplasty and combined intravenous-inhalational anaesthesia for septorhinoplasty.

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.
