Randomized Controlled Trial Comparative Study Clinical Trial Controlled Clinical TrialComparison of two methods of intravenous administration of morphine for postoperative pain relief.
Morphine sulphate was used for the control of pain following major abdominal surgery for a period of three days either as patient-controlled or continuous infusion. The two groups of patients were comparable with regard to patient and operation details, duration of infusion, pain scores and complications. ⋯ It is suggested that a properly supervised continuous infusion of morphine is as good as patient-controlled administration. There was a negative correlation between the age of the patient and the dose of morphine used.

Randomized Controlled Trial Comparative Study Clinical TrialThe perioperative effects of oral premedication in children.
The pre- and postoperative effects of oral diazepam (0.5 mg/kg), trimeprazine (4 mg/kg), pentobarbitone (3 mg/kg) and a placebo were compared in a randomized double-blind clinical trial in 149 children, aged one to ten years, undergoing adenotonsillectomy. The anaesthetic was standardised and each patient received intraoperative intramuscular papaveretum (0.3 mg/kg). ⋯ There were no differences in waking times between the diazepam, pentobarbitone and placebo groups, but the trimeprazine group's waking times were significantly prolonged (P less than 0.001). However, the trimeprazine group exhibited significantly less distress in the recovery unit (P = 0.02) and had half the incidence of vomiting (P less than 0.001) than did the other premedication groups.

Randomized Controlled Trial Clinical TrialGastric aspiration at the end of anaesthesia does not decrease postoperative nausea and vomiting.
Two hundred and one women undergoing elective abdominal hysterectomy were anaesthetised with isoflurane in nitrous oxide and oxygen. At the end of anaesthesia the stomach was aspirated in half of the patients, selected in random order. In the other half no aspiration was performed. ⋯ Emesis was similar after the operation regardless of aspiration of the stomach (overall emesis, 79% and 70% for those whose stomach had and had not been aspirated, respectively). The incidence at all times during the 24 hours was similar in both groups. The results suggest that gastric aspiration at the end of anaesthesia has no major effect on the incidence or severity of postoperative emesis in patients undergoing abdominal hysterectomy.

Randomized Controlled Trial Clinical TrialDouble-blind study of the reversal of midazolam-induced sedation in the intensive care unit with flumazenil (Ro 15-1788): effect on weaning from ventilation.
Midazolam (0.1-0.2 mg/kg/hr) and morphine (2 mg/hr) were given by carefully regulated continuous intravenous infusions to thirty patients who required sedation, analgesia and ventilation for between twelve and twenty-four hours in the Intensive Care Unit. The midazolam and morphine infusions were stopped at the end of the period of sedation required and the efficacy of placebo of flumazenil in reversing the sedative effects of midazolam was compared in this double-blind randomised parallel group study. Patients receiving flumazenil were less sedated (P less than 0.05), able to obey commands (P less than 0.05), weaned from ventilation (P less than 0.05) and extubated (P less than 0.05) significantly earlier than those receiving placebo.
