The cerebral and systemic metabolic and vascular effects of gammahydroxybutyrate and its lactone analogue, gammabutyrolactone, are addressed in this paper. In anesthetized normal dogs, gammahydroxybutyrate or gammabutyrolactone was infused intravenously at a rate of 1 gm\/kg\/hr. Cerebral blood flow (CBF) decreased progressively with increasing doses of either agent. Cerebral metabolic rate of oxygen (CMRO<jats:sub>2<\/jats:sub>) increased initially with gammahydroxybutyrate, but not following gammabutyrolactone. Reduction in CBF exceeded that of CMRO<jats:sub>2<\/jats:sub> at all doses in both series.<\/jats:p>\n<jats:p content-type=\"fine-print\">The primary systemic effect noted was a severe, lethal metabolic acidosis resulting from infusion of gammabutyrolactone. Gammahydroxybutyrate did not cause a similar acidosis. The imbalance of the CBF-CMRO<jats:sub>2<\/jats:sub> reduction following gammahydroxybutyrate administration suggests that it has no advantage over barbiturates in the management of patients with cerebral vascular insufficiency or intracranial hypertension.<\/jats:p>","DOI":"10.3171\/jns.1982.57.2.0197","type":"journal-article","created":{"date-parts":[[2009,5,8]],"date-time":"2009-05-08T13:56:49Z","timestamp":1241791009000},"page":"197-202","source":"Crossref","is-referenced-by-count":2,"title":["The effects of gammahydroxybutyric acid on canine cerebral blood flow and metabolism"],"prefix":"10.3171","volume":"57","author":[{"given":"Kent W.","family":"Baumann","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Neal F.","family":"Kassell","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Julie","family":"Olin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thoru","family":"Yamada","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"J Neurochem","doi-asserted-by":"publisher","first-page":"1114","DOI":"10.1111\/j.1471-4159.1980.tb07866.x","article-title":"\u03b3-hydroxybutyrate: cerebral metabolic, vascular, and protective effects.","volume":"35","author":"Artru","year":"1980"},{"key":"b2","series-title":"Stroke","doi-asserted-by":"publisher","first-page":"653","DOI":"10.1161\/01.STR.10.6.653","article-title":"Influence of various agents on the development of brain edema in the rat following microembolism.
