(A) Total number of operated rats per group stratified by survival. The number of animals per group was increased until n = 5 rats survived the 3 hour post-operative observation period. Mortality in animals anesthetized with chloral hydrate, isoflurane, or MMF was 50%, 17%, and 29%, respectively. (B) Number of animals which suffered a re-bleeding following SAH stratified by animals surviving (survivors) or not surviving (deaths) the post-operative observation period of 3 hours. Numbers of animals which died from anesthesia-induced complications are given in gray.
