Whole-brain blood flow and oxygen metabolism in the rat after halothane anesthesia. 1975

A Gjedde, and B Hindfelt

A recent modification of the Kety-Schmidt wash-out technique for 133xenon was used to measure whole-brain blood flow (CBF) and oxygen consumption (CMRO2) 1 to 4 hours after termination of halothane anesthesia in 15 Wistar rats. In this 3-hour experimental period, mean CBF and CMRO2 were reduced to 29 and 43% of control values, respectively. CBF and CMRO2 determined at the beginning and end of the experimental period were not significantly different from each other. Cerebral venous O2 tension was significantly higher than in the control group, supporting recent suggestions of a primary, intrinsic effect of halothane on the homeostatic control of this variable. It is concluded that halothane is not useful for cerebral metabolic studies in the rat.

D006221	Halothane	A nonflammable, halogenated, hydrocarbon anesthetic that provides relatively rapid induction with little or no excitement. Analgesia may not be adequate. NITROUS OXIDE is often given concomitantly. Because halothane may not produce sufficient muscle relaxation, supplemental neuromuscular blocking agents may be required.
