Randomized Controlled Trial Clinical Trial
Epidural sufentanil for post-operative pain relief: effects of adrenaline.
The analgesic, respiratory and haemodynamic effects of epidural sufentanil 75 micrograms (Group 1) or sufentanil 75 micrograms with adrenaline 75 micrograms (Group 2) were studied in 20 patients following abdominal surgery in a double-blind randomized trial. Pain relief, assessed on a linear analogue scale, sedation, heart rate (HR), mean arterial pressure (MAP), respiratory rate (RR) and arterial carbon dioxide tension (PaCO2) were recorded before, and for 12 h after, injection. Good post-operative pain relief was obtained after 4 min in Group 1 and 6 min in Group 2. ⋯ The patients in Group 1 showed more marked sedation 1 h after injection. Changes of HR and MAP were similar in both treatment groups. Side-effects were observed more frequently in Group 2, although the differences were not significant.(ABSTRACT TRUNCATED AT 250 WORDS)

Randomized Controlled Trial Comparative Study Clinical Trial Controlled Clinical Trial
Nausea and vomiting after general anaesthesia with isoflurane, enflurane or fentanyl in combination with nitrous oxide and oxygen.
One-hundred and eighty patients undergoing elective abdominal hysterectomy were anaesthetized in random order with isoflurane, enflurane or fentanyl in combination with nitrous oxide and oxygen. Incidence and severity of emetic sequelae (none, nausea, retching or vomiting) were studied during the first 24 h after the operation. ⋯ There was no difference between the groups in the overall incidence of emetic sequelae during the time period of 2-24 h post-operatively (isoflurane 65%, enflurane 77% and fentanyl 77%). Significantly (P less than 0.02) more patients had emetic sequelae if they had experienced nausea or had vomited after previous anaesthetics.
