Randomized Controlled Trial Comparative Study Clinical Trial
Intraoperative warming therapies: a comparison of three devices.
To compare the effectiveness of three commonly used intraoperative warming devices. ⋯ The forced-air warmer applied to only a limited skin surface area transferred more heat and was clinically more effective (at maintaining central body temperature) than were the other devices. The characteristic early decrease in central temperature observed in all groups regardless of warming therapy is consistent with the theory of anesthetic-induced heat redistribution within the body.

Randomized Controlled Trial Comparative Study Clinical Trial
Esmolol hydrochloride for management of the cardiovascular stress responses to laryngoscopy and tracheal intubation.
In a double-blind, randomized, controlled prospective study, 30 grade ASA I/II patients received a continuous i.v. infusion of normal saline or esmolol hydrochloride before induction of anaesthesia and tracheal intubation. Arterial pressure and heart rate were measured to assess the pressor response to laryngoscopy and intubation. The heart rate decreased in the esmolol group before induction of anaesthesia. The pressor response to laryngoscopy was significantly less marked in the esmolol group.

Randomized Controlled Trial Clinical Trial
Electroconvulsive therapy-induced cardiac arrhythmias during anesthesia with methohexital, thiamylal, or thiopental sodium.
To determine the frequency of electroconvulsive therapy (ECT)-induced arrhythmias under methohexital, thiamylal, or thiopental sodium anesthesia with and without atropine premedication. ⋯ These data suggest that anesthesia for ECT therapy should be induced with methohexital to minimize the possibility of potentially life-threatening cardiac arrhythmias. Atropine premedication may further decrease the frequency of premature atrial contractions and bradycardia, while increasing the frequency of tachycardia.

Biography Historical ArticleDr Horace Wells: the discoverer of general anesthesia.
The discovery of anesthesia in the second quarter of the 19th century was one of the greatest advances in the history of medicine. This discovery has been variously attributed to Long, Wells, Morton, Jackson, and others. In this article, the authors place in perspective the role each of these men has played. The conclusion is that to Wells belongs the singular honor and title of discoverer.

A frequent dilemma facing the anaesthetist is the child with respiratory tract symptoms. The risks of anaesthesia and surgery in these patients have not been clearly established. ⋯ Two of the children had absent clinical signs, whilst the third had a normal chest X ray. However, during surgery and anaesthesia each child developed significant pulmonary collapse, associated with desaturation on oximetry.
