Randomized Controlled Trial Clinical TrialThe use of countercurrent heat exchangers diminishes accidental hypothermia during abdominal aortic aneurysm surgery.
Perioperative hypothermia is common and likely contributes to morbidity, but the efficacy of prophylactic fluid warning has hardly been analyzed systematically. We tested the hypothesis that the use of an infusion/blood warmer, based on the principle of countercurrent heat exchange, reduces incidence and degree of severe hypothermia following aortic surgery. ⋯ The efficacy of fluid/blood warmers has hitherto only been evaluated in bench tests. Our results demonstrate that the use of heat exchangers alone, while not completely preventing hypothermia, markedly reduces the incidence of severe perioperative hypothermia, and lessens its degree during abdominal aortic aneurysm surgery.

Investigations of the Centers for Disease Control into postoperative infections have implicated extrinsically contaminated propofol. ⋯ We conclude that, if standard hygienic precautions are taken, the risk of in-use contamination of intravenous anaesthetics is low. If strict hygienic guidelines are followed in handling propofol, this agent can be safely administered to patients.

Randomized Controlled Trial Clinical TrialIntra-articular tenoxicam relieves post-arthroscopy pain.
Nonsteroidal anti-inflammatory drugs have been documented to be effective in the treatment of postoperative pain. The aim of this study was to evaluate the analgesic effect of local intra-articular injection of tenoxicam compared with intravenous injection on postoperative pain after arthroscopy. ⋯ Intra-articular tenoxicam 20 mg provided better analgesia and decreased the requirements for postoperative analgesic compared with i.v. tenoxicam 20 mg.

Randomized Controlled Trial Comparative Study Clinical TrialEffect of pre- vs postoperative tonsillar infiltration with local anesthetics on postoperative pain after tonsillectomy.
Since pre-incisional peritonsillar infiltrations of local anesthetic solutions have been suggested to reduce postoperative pain after tonsillectomy, we compared the efficacy of either pre- or postoperative local anesthetic infiltration upon post-tonsillectomy pain. ⋯ These results suggest that the timing of peritonsillar infiltration with bupivacaine is not of clinical importance and does not affect the quality of postoperative analgesia in patients undergoing tonsillectomy.

Randomized Controlled Trial Comparative Study Clinical TrialFluid therapy with Ringer's solution versus Haemaccel following coronary artery bypass surgery.
Crystalloid and colloid infusion can be used in volume therapy following heart surgery. In this prospective, randomised study we compared Ringer's solution (group R) to Haemaccel (group H) following coronary artery bypass grafting. ⋯ We conclude that volume therapy with Haemaccel following heart surgery requires less volume and achieves better filling of the circulation compared to Ringer's solution.
