Anaesthesia
-
Eleven brain-dead organ donors were studied during surgery. Plasma levels of adrenaline and noradrenaline were measured before and after skin incision, upon sternotomy and 15, 30 and 45 min thereafter. ⋯ Plasma catecholamines increased promptly with the onset of surgical stimuli. We conclude that surgical stress can evoke an excessive rise of plasma adrenaline and noradrenaline and thus could impair allograft function.

Randomized Controlled Trial Comparative Study Clinical Trial
Prevention of nausea and vomiting after day case gynaecological laparoscopy. A comparison of ondansetron, droperidol, metoclopramide and placebo.
We have compared the efficacy of ondansetron, metoclopramide, droperidol and placebo in the prevention of postoperative nausea and vomiting in 118 day stay patients undergoing laparoscopic gynaecological procedures. All received a standardised general anaesthetic of fentanyl, propofol, nitrous oxide in oxygen and isoflurane. Three to five min before induction of anaesthesia, patients were allocated to receive ondansetron 4 mg, metoclopramide 10 mg, droperidol 1 mg or placebo in a randomised, double-blind manner. ⋯ The incidence of emesis was lower (p = 0.063) and time to first oral fluids was shorter (p < 0.05) in the ondansetron group. Oral analgesic requirements were significantly greater in the ondansetron group over the 48 h study period. Two patients, one each in the placebo and metoclopramide groups, had to remain in hospital overnight because of persistent emetic symptoms.
