Randomized Controlled Trial Comparative Study Clinical Trial
A comparison: the efficacy of sevoflurane-nitrous oxide or propofol-nitrous oxide for the induction and maintenance of general anesthesia.
To compare sevoflurane-nitrous oxide with propofol-nitrous oxide for the induction and maintenance of anesthesia, and to determine the rates of recovery following each anesthetic. ⋯ Sevoflurane allows for rapid inhalation induction of, and emergence from, general anesthesia.

The effect of sedation on ICU patient recall is uncertain. Ensuring suppression of awareness and, particularly, recall, may prevent post-ICU psychological problems. Development of ICU sedation pathways and improved neurophysiologic monitoring techniques may help clinicians provide good levels of recall suppression and sedation when they are most needed by ICU patients.

To study the safety of instillation of eyedrops prior to ophthalmic surgery, which may potentially affect myocardial function, using continuous ST segment recording. ⋯ The lack of significant finding most likely reflects the safety of these ophthalmic drops in their present dilute concentration, but it is also possible that the software and/or monitors used were not sensitive enough in their current configuration to detect possible subtle changes. Based on the results of this study, we conclude that the preoperative ophthalmic drugs used in our institution do not seem to have any adverse cardiovascular effects in this elderly patient population who are about to undergo cataract surgery with MAC.

An abrupt decrease in end-tidal carbon dioxide (CO2) occurred in an anesthetized male who was placed in the head down position during radical perineal prostatectomy. The end-tidal CO2 was restored after insertion of a wet pack into the operative site, which strongly indicated venous air embolism as the cause. Predisposing factors, detection, and treatment of venous air embolism in this setting are discussed.
