The purpose of this study was to examine the effects of ketamine and pentobarbital on venous capacitance in rats. Venous capacitance was assessed by measuring the mean circulatory filling pressure (MCFP) at three levels of blood volume in conscious rats as well as during anesthesia with ketamine (125 mg/kg, ip) or pentobarbital (50 mg/kg, ip). MCFP was measured during brief periods of circulatory arrest produced by inflating an indwelling balloon in the right atrium. ⋯ These results suggest that ketamine did not alter but pentobarbital increased venous capacitance. The slope of the regression line relating MCFP and blood volume was not altered by ketamine but was increased (P less than 0.05) by pentobarbital, which suggests that ketamine did not alter but pentobarbital decreased total vascular compliance. These results suggest that ketamine maintains but pentobarbital decreases venous tone.

In order to continue to enhance the educational quality of residency training in anesthesiology and ultimately to improve patient care, the American Board of Anesthesiology has adopted a modification in the curriculum for the 4-year Continuum of Education in Anesthesiology to provide for a CA-3 year replacing the Specialized Year and the Alternate Pathways. This CA-3 year will be required for residents beginning their CA-1 year of training on or after May 1, 1986. There will be a 2-year transition period beginning May 1, 1984, to facilitate its implementation.

Beware anesthesiologist number 7... the quality of intraoperative conduct of anesthesia effects patient outcomes.
