Dantrolene and HCO3- acted separately and differently: dantrolene reversed the hypermetabolism, both aerobic and anerobic, and HCO3- reversed the extracellular metabolic acidosis. Semitendinosus muscle biopsies demonstrated that both red and white muscle are involved in MH, that muscle lactate (to 35 mumol X g-1) consistently exceeded blood lactate (to 22 mumol X ml-1), and that blood lactate levels were slow to diminish following treatment. One could expect continued release of muscle lactate into blood, despite adequate therapy of MH; this might suggest a recurrence even when such is not the case.</p>","PeriodicalId":9371,"journal":{"name":"Canadian Anaesthetists' Society journal","volume":"33 6","pages":"729-36"},"PeriodicalIF":0.0,"publicationDate":"1986-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/BF03027122","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14228577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lower total and per diem ICU charges were observed for elective surgical patients, patients with lower severity of illness as assessed by the Therapeutic Intervention Scoring system and survivors. Emergency admissions were more expensive than elective admissions when compared for total ICU admission costs. Length of stay was a significant factor in overall ICU costs.
