Randomized Controlled Trial Comparative Study Clinical Trial
The effect of the laryngeal mask airway on coughing after eye surgery under general anesthesia.
Twenty-nine patients scheduled for elective eye surgery under general anesthesia were randomized into two groups, A and B. After induction of anesthesia, the airway of those in group A was maintained with a conventional tracheal tube; in group B, with a laryngeal mask airway. In the immediate postoperative period, 13 of the 14 patients in group A coughed; none of those in group B did (P < .001).

Comparative Study
Regurgitation of gastric contents during general anaesthesia using the laryngeal mask airway.
We have investigated the incidence of regurgitation of gastric contents during general anaesthesia administered via a laryngeal mask airway (LMA) or face mask and Guedel airway in 56 patients with no risk factors for regurgitation. Patients swallowed a gelatin capsule containing methylene blue 10 min before induction of anaesthesia. ⋯ No patients in the face mask-Guedel airway group regurgitated dye (P = 0.005). There was no evidence of aspiration of dye.

To determine whether data recorded by an information management system is significantly different from that recorded manually. ⋯ Observer bias, missed readings, and errors of memory, which affect manual anesthetic records, may cause significant inaccuracy and may be avoided by using automated records generated by information management systems.

[The hemodynamic effects of ketamine anesthesia in children with congenital heart diseases].
One hundred and thirty five children have been examined after surgery for congenital heart valve defects performed under ketamine anesthesia. It has been established that ketamine anesthesia has no considerable effect on the preload and cardiac pump function. ⋯ A spasm in the vessels of the conjunctiva is observed even when small drug doses are used. This may be accounted for by calcium accumulation in the muscular cells, noradrenaline hyperproduction, enhanced sensitivity of sympathomimetic receptors to circulating endogenous catecholamines.
