Comparative StudyComputerized data collection in the operating room during coronary artery bypass surgery: a comparison to the hand-written anesthesia record.
To investigate variability between hand-written and computerized anesthesia records and evaluate any associated bias. ⋯ Because of the lack of explained variability between the computer system and hand-written anesthesia records and the bias in the hand-written anesthesia record, the hand-written anesthesia record should not be relied on as a source of accurate data for research purposes.

Comparative StudyA comparison of two different bronchial cuff designs and four different bronchial cuff inflation methods.
To compare directly measured pressures at the cuff/trachea interface that are associated with two different bronchial cuff designs and four different methods of bronchial cuff inflation suggested for use with one-lung ventilation. ⋯ To achieve lung separation with the lowest pressure on the trachea, the new test is the most appropriate method for use with the double-lumen tube; however, the negative-pressure test appeared to be the easiest and fastest method for use with the bronchial blocker. Although the bronchial blocker was associated with lower pressures transmitted from the cuff to the trachea, the in vitro model cannot predict which bronchial cuff design would be superior in vivo.

Topical ice slurry prevents brain rewarming during deep hypothermic circulatory arrest in newborn sheep.
To measure the effect of ice slurry topical cooling on brain surface temperature during deep hypothermic circulatory arrest. ⋯ Topical cooling of the head with ice slurry in newborn lambs lowers brain surface temperature during deep hypothermic circulatory arrest. Surrogate temperature monitoring locations such as nasopharyngeal and rectal temperatures varied significantly and do not accurately reflect changes in brain surface temperature.

Randomized Controlled Trial Comparative Study Clinical TrialGlucose versus lactated Ringer's solution during pediatric cardiac surgery.
Whether intraoperative fluid infusion should contain glucose during pediatric cardiac surgery remains controversial. This study was performed to compare the effects of glucose and glucose-free solutions on blood glucose and blood insulin levels during total repair of congenital heart diseases. ⋯ Glucose withdrawal during pediatric cardiac surgery induces threatening hypoglycemia during the prabypass period, and moderate intraoperative glucose administration (2.5 mg/kg/min) is not responsible for major hyperglycemia.
