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 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.

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.

Pre-eclampsia: the effect of intravenous fluid preload on atrial natriuretic peptide secretion during caesarean section under spinal anaesthesia.
The haemodynamic effect of volume load at elective Caesarean delivery may be modulated by atrial natriuretic peptide (ANP) especially in pre-eclamptic women in whom basal ANP levels are increased. ⋯ These findings concur with the theory that atrial stretch is a stimulus for ANP release. An exaggerated release of ANP in response to volume loading may aid in the adaptation of maternal circulation to volume load at elective Caesarean delivery in pre-eclamptic women.

Continuous end-tidal carbon dioxide monitoring during normofrequent jet-ventilation.
Continuous end-tidal carbon dioxide (ETCO2) monitoring during normofrequent jet-ventilation (NFJV) has not previously been successful and no correspondence between ETCO2 and arterial carbon dioxide (PaCO2) demonstrated. ⋯ A valuable method of continuous ETCO2 monitoring during NFJV is presented.
