Randomized Controlled Trial Comparative Study Clinical Trial
Infusions of subhypnotic doses of propofol for the prevention of postoperative nausea and vomiting.
We studied the antiemetic effects of a low dose infusion of propofol for 24 h after major gynaecological surgery in a double-blind, randomised, controlled trial. Fifty women of ASA physical status 1 or 2 undergoing major gynaecological surgery received an infusion of 1% propofol or intralipid at 0.1 ml.kg-1.h-1 for 24 h after surgery. Pain was managed using morphine delivered by a patient-controlled analgesia pump. ⋯ There were no differences between the two groups in any of the measures of postoperative nausea and vomiting during the first 48 h after surgery. Postoperative nausea and vomiting in the control group was less on the second day compared with the first postoperative day, but not in the propofol group. There were no side effects from the propofol infusion.

Randomized Controlled Trial Clinical Trial
Analgesia for day surgery. Evaluation of the effect of diclofenac given before or after surgery with or without bupivacaine infiltration.
One hundred patients undergoing breast lump excision using a standard anaesthetic technique in the Day Care Unit were randomly divided into five groups. Groups A and B received either saline or diclofenac in a double-blind fashion before and at the end of the procedure, with both groups receiving 10 ml of 0.5% bupivacaine infiltration at the end. Groups C and D also received saline or diclofenac before and after surgery but had no bupivacaine infiltration at the end. ⋯ Although not significant (p = 0.22), fewer patients required rescue medication when diclofenac was given before surgery (10%) rather than after surgery (22.5%). Fewer patients had a fair amount or a great deal of pain in the 48 h following surgery when diclofenac was injected before (7.5%) rather than after surgery (12.5%). The mean number of oral analgesics taken in the 48 h after surgery was also lower in those patients who had the diclofenac before the surgery rather than after.

Randomized Controlled Trial Clinical Trial Retracted Publication
The influence of volume therapy and pentoxifylline infusion on circulating adhesion molecules in trauma patients.
Adhesion molecules appear to play a pivotal role in tissue damage secondary to the inflammatory process. Besides neutrophil- and endothelial-bound adhesion molecules, soluble forms have been detected in the circulating blood. They seem to be good markers of endothelial damage, but they may also have other biological functions. ⋯ We conclude that volume therapy with hydroxyethyl starch resulted in a decrease in circulating adhesion molecules in our trauma patients. In contrast, volume therapy with albumin did not exert this effect. Continuous infusion of pentoxifylline did not have a beneficial modulating action on circulating adhesion molecules.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
A comparison of the recovery characteristics of sevoflurane and halothane in children.
The recovery characteristics of sevoflurane and halothane anaesthesia were compared in 40 children aged 6 months to 6 years undergoing day case surgery. The mean time taken to open eyes after surgery had ended was appreciably and significantly shorter after sevoflurane than after halothane (sevoflurane, mean time (SD) 7 min 52 s (5 min 46 s), halothane, mean time (SD) 15 min 50 s (9 min 2 s), t = 3.32, p = 0.002). ⋯ However, more children were in pain and given analgesia after sevoflurane (p < 0.01) and the mean time to reach the criteria for discharge home was similar in both groups (sevoflurane, mean time (SD) 2 h 9 min (17 min), halothane, mean time (SD) 2 h 4 min (8 min)). There were no major complications in either group.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
A comparison of the induction characteristics of sevoflurane and halothane in children.
The induction characteristics of sevoflurane and halothane were compared in 81 children aged 6 months to 6 years. The mean time taken to achieve loss of eyelash reflex was significantly shorter with sevoflurane than with halothane (sevoflurane, mean time (SD) 1 min 41 s (35 s), halothane, mean time (SD) 2 min 17 s (43 s), t = 4.11, p = < 0.01). ⋯ Effects on heart rate, blood pressure and oxygen saturation during induction were similar for both agents. There were no major complications during induction with either halothane or sevoflurane.
