Intraoperative patient-controlled analgesia: an alternative to physician administration during outpatient monitored anesthesia care.

Outpatients undergoing minor diagnostic and therapeutic procedures associated with intermittent discomfort are frequently given bolus injections of intravenous opioid analgesics. In a group of 80 healthy women undergoing vaginal ovum pickup procedures, we evaluated patient-controlled administration of alfentanil using a patient-controlled analgesia device (with a lockout interval of 3 min) as an alternative to conventional physician-controlled administration. The two alfentanil administration techniques were equally effective in providing intraoperative analgesia. The average alfentanil dosage requirements were 1.49 +/- 0.50 and 1.46 +/- 0.55 micrograms.kg-1.min-1 (mean +/- SD) in the physician- and patient-controlled groups, respectively. The incidence of postoperative nausea was the same in both treatment groups (8%). Even with the mandatory lockout interval, intraoperative patient-controlled administration of alfentanil was comparable to physician-controlled administration with respect to patient comfort and satisfaction during vaginal ovum pickup procedures.

Pre-bypass myocardial ischaemia in patients undergoing coronary artery surgery.

One hundred patients undergoing elective coronary artery surgery were studied to determine the incidence of pre-bypass myocardial ischaemia. Leads II, aVF and V5 of the electrocardiogram (ECG) were recorded at five-minute intervals from arrival in the anaesthetic room until onset of cardiopulmonary bypass. Thirteen patients developed sixteen episodes of significant ST depression on the ECG during the study period. Three patients were diagnosed as having postoperative myocardial infarction by ECG criteria and creatine phosphokinase-MB rise above 80 units. None of these patients had pre-bypass ST depression. Comparisons of these results with similar studies are presented.
