Use of the bispectral index during the early postresuscitative phase after out-of-hospital cardiac arrest.
Non-invasive and real-time measures of neurological status after cardiac arrest are needed to be able to make an early determination of the postresuscitative outcome. We investigated whether the bispectral index (BIS) predicts the postresuscitative outcome in 10 patients with out-of-hospital cardiac arrest. We measured the BIS after return of spontaneous circulation (ROSC) in the emergency room and on admission to the intensive care unit (ICU). ⋯ The BIS values were significantly lower in the nonsurviving group than in the surviving group. There was a positive correlation between the BIS on admission to the ICU and the GOS on discharge from the ICU. The BIS can thus be used to predict the postresuscitative outcome of patients with out-of-hospital cardiac arrest.

Dose effects of propofol on hemodynamic and cytokine responses to endotoxemia in rats.
Our previous studies have demonstrated that propofol inhibits hypotension, metabolic acidosis, and cytokine responses and reduces mortality in endotoxemic rats. The purpose of this study was to elucidate whether these beneficial effects of propofol on hemodynamics and cytokine responses were dose related. ⋯ The effects of propofol on blood pressure and cytokine responses were influenced by the dose of propofol, although the relationship did not follow simple linearity.

Case ReportsAirway obstruction involving a laryngeal mask airway during arthroscopic shoulder surgery.
Several earlier reports have described life-threatening airway obstruction during arthroscopic shoulder surgery performed under regional anesthesia, caused by the leakage of irrigation fluid out of the shoulder joint space into the surrounding soft tissues and then the neck and the pharynx. Here, we present a case of airway obstruction that occurred in a patient under general anesthesia. A 77-year-old woman with a rotator cuff rupture who was to undergo right-shoulder arthroscopic surgery was anesthetized with fentanyl and propofol. ⋯ She was placed in the Fowler position and furosemide was given intravenously. Her neck and chest swelling were reduced over the next 2 h and she was extubated without any problem. We recommend that physicians should periodically examine the neck of any patient undergoing arthroscopic shoulder surgery, especially when general anesthesia is used, because anesthetized patients cannot complain of breathing difficulty and the airway swelling may progress until it becomes life-threatening.

Historical ArticleUsing digital media to keep anesthesia history alive.
Multimedia applications have been developed to explain many aspects of anesthesiology, including anesthesia machines, cardiopulmonary bypass systems, airway management, anesthetic pharmacology, regional anesthesia, and more recently, the history of the specialty. This article describes how computer-assisted instruction and multimedia have made it possible for an anesthesia department in a teaching hospital to become involved in the preservation, publication, and distribution of historically related anesthesia materials. The production of a digital video disc (DVD) based on the career of Leroy D. Vandam is discussed to illustrate the value of digital media in preserving, rejuvenating, and distributing anesthesia-related historical materials.
