Randomized Controlled Trial Clinical Trial
Analgesic efficacy of tramadol 2 mg kg(-1) for paediatric day-case adenoidectomy.
We studied the analgesic efficacy of tramadol 2 mg kg(-1) for post-operative analgesia after day-case adenoidectomy in children aged 1-3 yr. Eighty children were allocated randomly to receive tramadol 2 mg kg(-1) i.v. or placebo immediately after induction of anaesthesia. Anaesthesia was induced with alfentanil 10 microg kg(-1) and propofol 4 mg kg(-1) followed by mivacurium 0.2 mg kg(-1) for tracheal intubation. ⋯ Forty-five per cent of children receiving tramadol did not require post-operative analgesia at all compared with 15% of children receiving placebo (P = 0.003). Recovery times and the incidence of adverse effects were similar in the two groups in the recovery room and at home. The requirement for rectal ibuprofen at home did not differ between groups.

Randomized Controlled Trial Clinical Trial
Antinociceptive properties of neurosteroids IV: pilot study demonstrating the analgesic effects of alphadolone administered orally to humans.
Fourteen patients scheduled for orthopaedic knee reconstruction surgery were enrolled in a prospective, double-blind, randomized study in which they received alphadolone (25-500 mg, n = 9) or placebo (lactose, n = 5) given orally 1 h after operation. All the subjects received a standardized general anaesthetic and the same type of surgery followed by physiotherapy using a continuous passive movement machine. Morphine was administered intravenously after operation by patient-controlled analgesia. ⋯ The experiences of these side-effects were all rated as none, mild or moderate. Orally administered alphadolone caused statistically significant reductions in morphine use and simultaneous highly significant reductions in pain scores. We conclude that alphadolone is a useful analgesic in humans when given by the oral route.

Randomized Controlled Trial Comparative Study Clinical Trial
Intrapartum epidural catheter migration: a comparative study of three dressing applications.
We compared three types of catheter fixation application for their ability to minimize the incidence and magnitude of epidural catheter movement during labour. Patients were randomized to have their epidural catheter secured by a Tegaderm dressing (group T; n = 35), a Tegaderm dressing plus filter-shoulder fixation (group F; n = 39), or a Niko Epi-Fix dressing (group N; n = 37). ⋯ Outward movement of the catheter was greatest when a Niko Epi-Fix was used (P < 0.01). Concerning minimization of displacement of the epidural catheter per se, only a Tegaderm dressing with additional filter-shoulder fixation proved more effective than using a Niko Epi-Fix dressing (P < 0.05).

Randomized Controlled Trial Comparative Study Clinical Trial
Small-dose selective spinal anaesthesia for short-duration outpatient gynaecological laparoscopy: recovery characteristics compared with propofol anaesthesia.
A randomized controlled trial compared recovery characteristics after selective spinal anaesthesia (SSA) or propofol general anaesthesia (GA) for short-duration outpatient laparoscopic surgery. Forty women were randomized to receive either SSA (1% lidocaine 10 mg, sufentanil 10 microg and sterile water 1.8 ml) or GA (propofol and nitrous oxide 50% in oxygen). Compared with the GA group, times to leaving the operating room, performing a straight leg raise, performing deep knee-bends and achieving an Aldrete score >9 and the time in Phase II recovery were significantly shorter (P < 0.05) in the SSA group.

Randomized Controlled Trial Clinical Trial
Reduced haemostatic factor transfusion using heparinase-modified thrombelastography during cardiopulmonary bypass.
We set out to determine if the heparinase-modified thrombelastogram using anticoagulated blood from patients during cardiac surgery could guide treatment with haemostatic components. In 60 patients a simple algorithm predicted a possible 60-80% decrease in the use of haemostatic components. ⋯ Ten patients in the clinical group received a total of 16 units of fresh frozen plasma and nine platelet concentrates compared with five patients transfused with five units of fresh frozen plasma and one platelet concentrate in the algorithm group. Twelve-hour chest tube losses [algorithm group 470 (295-820) ml, clinically managed group 390 (240-820) ml (median, quartile values)] were not different between groups despite the threefold reduction in the use of haemostatic products, showing that intra-operative monitoring of coagulation in the anticoagulated patient can be used to guide treatment.
