Anaesthesia
-
We have evaluated the Airway Management Device (AMD) in 105 anaesthetised patients. We were successful in establishing a clear airway on the first attempt on 69 occasions and unable to establish a patent airway at all in 10 patients. Airway obstruction requiring removal of the device occurred during maintenance of anaesthesia in a further two cases and during emergence in three. ⋯ Intracuff pressure was measured in 12 cases and was above 100 cmH2O in eight. Minor complications occurred in 12 patients. Blood was visible on removal of the device in six cases.

Randomized Controlled Trial Clinical Trial
Combined pre-incisional oral dextromethorphan and epidural lidocaine for postoperative pain reduction and morphine sparing: a randomised double-blind study on day-surgery patients.
The reduction in acute pain perception following dextromethorphan has previously been investigated in patients undergoing general anaesthesia. This random and double-blind study examined the effects of pre-incisional oral dextromethorphan on postoperative pain and intravenous patient-controlled morphine demand in 60 day-surgery patients undergoing lower body surgery under lidocaine (1.6%-16 ml) epidural anaesthesia after receiving placebo, 60 or 90 mg dextromethorphan, 90 min pre-operatively. Postoperative pain was scored on a visual analogue scale from 1 to 10. ⋯ Dextromethorphan-treated patients reported significantly (p < 0.05) less pain and sedation, and felt better. Patients who received dextromethorphan 90 mg had significantly (p < 0.05) lower heart and respiratory rates than those who received 60 mg. Medicated patients required half the morphine and diclofenac of placebo patients: 38% of patients who received 90 mg and 21% who received dextromethorphan 60 mg used no morphine or diclofenac whatsoever, a previously unreported finding.
