The influence of fentanyl on an alfathesin infusion technique.

The effects of fentanyl (1 microgram/kg) supplementing an alfathesin infusion technique were assessed in a double blind study in 53 healthy unpremedicated female patients undergoing therapeutic abortion as outpatients. The addition of fentanyl reduced the tachycardia, tachypnoea and hyperventilation seen in those patients receiving alfathesin alone, without unduly prolonging recovery time. Two patients receiving alfathesin alone developed marked coughing or laryngospasm. Fentanyl would seem to be a desirable addition to an alfathesin infusion technique in unpremedicated patients presenting for outpatient anaesthesia.
