[The Effectiveness of Two Anesthesia Machines in the Water Generation of the Anesthesia Circuit during the Prolonged Low Flow Desflurane Anesthesia].

Background: Water is generated by a reaction of carbon dioxide and a carbon dioxide absorbent We evaluated the effectiveness of the anesthesia machines about the water generation which occurs to an anes- thetic circuit during the prolonged low flow anesthesia.

Methods: Fifteen patients were divided into three groups; group HHS (n=5) in which a hot heater system was equipped inside anesthesia machine, group WCD (n=5) in which a water catchment device was connected with anesthesia machine, and control group N(n=5)in which normal anesthesia machine was used without special device, and studies were performed with FGF 11 - min- low flow desflurane anesthesia for more than 6 hours. The water situation in an anesthe- sia circuit was observed during the operation and was compared after the operation between these groups.

[Difficult airway management due to obesity and lingual tonsillar hyperplasia].

We experienced anesthesia for a female patient of BMI 39.2 with unanticipated lingual tonsillar hyperplasia. At the induction of anesthesia, both mask ventilation and tracheal intubation were difficult due to the lingual tonsillar hyperplasia.

Plasma-induced endothelial oxidative stress is related to the severity of septic shock.

Objective: To estimate the capacity of plasma from septic shock patients to induce in vitro reactive oxygen species (ROS) production by endothelial cells and to analyze whether ROS production is related to the severity of the septic shock.

Design: Prospective, observational study.

Setting: Medical intensive care unit in a university hospital.
