Randomized Controlled Trial Clinical Trial
Intramuscular NSAIDS reduce post-operative pain after minor outpatient anaesthesia.
Two hundred healthy patients scheduled for elective minor gynaecological surgery under general anaesthesia were randomly allocated to one of four groups who received either diclofenac 75 mg intramuscularly (i.m.), ketorolac 30 mg i.m., diclofenac 50 mg orally, or 2 mL NaCl i.m. The drugs were administered 10-20 min prior to a standard anaesthetic. ⋯ Complaints about pain and need for post-operative analgesics were significantly less frequent in the two groups of patients receiving an intramuscular non-steroidal anti-inflammatory drug (NSAID), as compared to placebo. The patients who received 50 mg diclofenac orally, administered shortly before the procedure, had the same pain course as the placebo patients.

Randomized Controlled Trial Comparative Study Clinical Trial
Nausea and vomiting after laparoscopic surgery: a comparison of propofol and thiopentone/halothane anaesthesia.
Sixty ASA I and II patients scheduled for laparoscopic cholecystectomy or inguinal herniotomy were randomly assigned to one of two groups: Group one (n = 30): induction with thiopentone 4-6 mg kg-1, fentanyl 2 micrograms kg-1, pancuronium 0.03 mg kg-1, and succinylcholine 1 mg kg-1, maintainance with halothane (0.8-1.5%), and N2O in O2 (FiO2 = 0.33). Group two (n = 30): induction with propofol 2-3 mg kg-1, fentanyl 2 micrograms kg-1, pancuronium 0.03 mg kg-1, and succinylcholine 1 mg kg-1, maintainance with propofol 6-10 mg kg-1 h-1, and O2 in N2 (FiO2:0.33). ⋯ The overall incidence of emetic sequelae (nausea or vomiting) was 43% in group one and 23% in group two (P = 0.17). Patients with propofol anaesthesia had lower emetic scores and higher recovery scores compared with those after thiopentone/halothane anaesthesia.

Randomized Controlled Trial Comparative Study Clinical Trial
A comparison between total intravenous anaesthesia using a propofol/alfentanil mixture and an inhalational technique for laparoscopic gynaecological sterilization.
Thirty patients undergoing laparoscopic gynaecological sterilization, as day-cases, were randomly allocated to receive either total intravenous anaesthesia (TIVA) with a propofol and alfentanil mixture or a standard inhalational technique. Immediate recovery, as measured by times to awakening, co-operation and orientation, and psychomotor recovery, as measured by 'P' deletion studies, were not significantly different between the two groups. ⋯ There were no differences between the two groups with respect to suitability for discharge home and no incidences of awareness. We conclude that TIVA with a propofol and alfentanil mixture provides satisfactory anaesthesia for gynaecological sterilization, with good recovery characteristics and a low incidence of post-operative nausea and vomiting.

Randomized Controlled Trial Comparative Study Clinical Trial
Post-operative intravenous continuous analgesia: comparison of buprenorphine, fentanyl and nalbuphine.
Continuous intravenous infusions of fentanyl, buprenorphine or nalbuphine were investigated to provide pain relief for patients after major abdominal surgery. Buprenorphine (n = 23) was given as a loading dose of 5 micrograms kg-1 and infused at 0.8 micrograms kg-1 h-1. Fentanyl (n = 20) was given as a loading dose of 2 micrograms kg-1 and infused at 0.7 micrograms kg-1 h-1. ⋯ The infusion rate was increased when analgesia was inadequate, and decreased if respiratory depression occurred. Mean doses were respectively 0.74 +/- 0.15 microgram kg-1 h-1 buprenorphine, 0.68 +/- 0.18 microgram kg-1 h-1 fentanyl, 83 +/- 21 micrograms kg-1 h-1 nalbuphine. Titration of continuous intravenous infusion of buprenorphine and fentanyl provided better analgesia than nalbuphine with smaller doses than those reported in similar studies allowing spontaneous breathing.

Randomized Controlled Trial Clinical Trial
Effect of nitrous oxide on middle ear pressure: a comparison between inhalational anaesthesia with nitrous oxide and TIVA.
We have investigated the effect of nitrous oxide on the middle ear pressure, comparing inhalational anaesthesia with nitrous oxide and halothane and total intravenous anaesthesia with propofol-alfentanil. Fifty patients with normal healthy ears were divided into two groups. In one group (n = 25), anaesthesia was induced with thiopentone 6 mg kg-1, and maintained with halothane 1% and nitrous oxide 66% in oxygen. ⋯ A progressive rise was observed (P < 0.05) in the first group, whereas values were within the normal limits clinically and there was no statistically significant change in those receiving total intravenous anaesthesia during the intra-anaesthetic period. The time to reach peak pressure with inhalational anaesthesia was 60 min (181.5 mmH2O) and to return to normal was 30 min (49.5 mmH2O) after cessation of nitrous oxide administration. The incidence of nausea and vomiting was less in the patients not receiving nitrous oxide.
