Clinical Trial
Postoperative myocardial ischemia: etiology of cardiac morbidity or manifestation of underlying disease?
To determine the relationship between postoperative ST segment changes and clinically apparent cardiac morbidity in noncardiac surgery patients. ⋯ These observations suggest that clinically apparent cardiac events are associated with prolonged ST segment changes detected on ambulatory ECG recorders. The cardiac ischemia leading to prolonged postoperative ST segment changes may itself result in cardiac morbidity, or it may be a reflection of underlying pathophysiology.

The dorso-radial aspect of the wrist and hand is a common location for intravenous (IV) cannulation prior to anesthesia. The sensory branch of the radial nerve lies superficially in this area, and it can be injured during routine insertion of IV catheters. In this case, the nerve was lacerated during insertion and a painful neuroma developed after elective surgery and anesthesia. Knowledge of this complication may help with its recognition and treatment.

Randomized Controlled Trial Comparative Study Clinical Trial
Antiemetic efficacy of a droperidol-morphine combination in patient-controlled analgesia.
To evaluate the antiemetic effectiveness and side effects of adding low-dose droperidol to morphine delivered via a patient-controlled analgesia (PCA) device. ⋯ An intermittent intake of low-dose droperidol with morphine given via a PCA delivery system in two treatment groups gave evidence for a dose-response relation between the amount of droperidol added and the proportion of patients needing a rescue antiemetic. The same result applied to the proportion of patients having an emetic episode and the number of times a rescue antiemetic had to be administered. There was no evidence that the low dose of droperidol added to morphine delivered via a PCA device increased unwanted side effects.

Randomized Controlled Trial Comparative Study Clinical Trial
Laryngeal mask airway: a more successful method of insertion.
To compare the ease of insertion of the laryngeal mask airway (LMA) by two methods. ⋯ Inserting the LMA with the cuff partially inflated is likely to be more successful than with the cuff fully deflated. When it is not possible to insert the LMA with the cuff fully deflated, partial inflation before insertion may result in correct placement.
