Randomized Controlled Trial Clinical Trial
Blood salvage during caesarean section.
The aim of this study was to assess blood salvage during Caesarean section. In 15 Caesarean sections, red cells lost were collected and washed with a Dideco machine and tested for the presence of fetoplacental material, bacterial contamination, free haemoglobin and fetal blood cells. Successive patients were allocated randomly to one of two groups. ⋯ Duration of hospital stay was significantly shorter in group 1 (5.3 (1.9) vs 7.3 (4) days; P = 0.003). Mean base haemoglobin concentrations were significantly lower in group 1 (10.7 (1.4) vs 11.7 (1.5) g dl-1; P > 0.0001), while after surgery mean haemoglobin concentrations were significantly higher approximately 3 h after operation compared with the control group (10.2 (1.5) vs 8.6 (1.2) g dl-1; P < 0.0001). On the first day, haemoglobin concentrations were 9.8 (1.5) vs 8 (1.4) g dl-1 (P < 0.0001), on the second day 9.8 (1.4) vs 7.7 (1.4) g dl-1 (P < 0.0001), on the third day 10.1 (1.5) vs 7.5 (1.3) g dl-1 (P < 0.0001) and on the fourth day 10.4 (1.5) vs 8.1 (1.4) g dl-1 (P < 0.0001).

Randomized Controlled Trial Clinical Trial
Combining propofol with morphine in patient-controlled analgesia to prevent postoperative nausea and vomiting.
We have studied the antiemetic effects of propofol when mixed with morphine in a patient-controlled analgesia (PCA) pump after major gynaecological surgery. In a double-blind, randomized, controlled study, 50 women, ASA I or II, received a standardized anaesthetic comprising thiopental, morphine, atracurium, nitrous oxide and oxygen with enflurane, and received postoperative PCA with morphine mixed with either 1% propofol or lvelip. The PCA bolus was morphine 1 mg with propofol 5 mg or lvelip 0.5 ml, with a lockout time of 5 min. ⋯ There were no significant differences between the two groups in any of the study measurements of PONV. There were, no side effects after propofol. Propofol, when mixed with morphine in this dose combination for PCA, did not decrease the incidence of nausea and vomiting in women undergoing major gynaecological surgery.

Randomized Controlled Trial Clinical Trial
Pre-emptive effect of multimodal analgesia in thoracic surgery.
Thirty subjects undergoing posterolateral thoracotomy were allocated randomly to receive one of two analgesic regimens: group Pre received i.v. morphine, i.m. diclofenac and intercostal nerve blocks from T2 to T11, 20 min before operation and placebo injections after operation. Group Post received placebo injections before operation, and i.v. morphine, i.m. diclofenac and intercostal nerve blocks from T2 to T11 at the end of surgery, before discontinuation of anaesthesia. ⋯ During the first 48 h after operation there were lower pain scores in group Pre when taking a vital capacity breath but there were no significant differences between the groups in any other measure. The effects of pre-emptive analgesia given before surgery appeared to be relatively modest in terms of analgesia, analgesic consumption and long-term outcome and were of limited clinical significance.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of intubating conditions after rocuronium or vecuronium when the timing of intubation is judged by clinical criteria.
The onset of action and intubating conditions after rocuronium 0.6 mg kg-1 or vecuronium 0.1 mg kg-1 were compared in a randomized, double-blind study when the timing of tracheal intubation was determined by clinical judgment alone. Times to laryngoscopy and completion of intubation were mean 89 (SD 20) s and 119 (28) s, respectively, in the rocuronium group compared with 110 (26) s and 142 (32) s in the vecuronium group (P < 0.05 in both cases). Recuronium also resulted in significantly better intubating conditions compared with vecuronium but with no significant reduction in the haemodynamic response to intubation. We found that onset of satisfactory intubating conditions after rocuronium was detected clinically, although even earlier intubation should be possible by careful timing or by neuromuscular monitoring.
