Abstract
Background: The dosage of the anesthetic drugs is generally determined by the total body weight of the patients. However, the drugs can be overdosed when the patient is morbidly obese. We have determined anesthetic induction dose based on lean body mass estimated from bioelectrical impedance analysis (BIA). Case: We report a case of morbidly obese patient (161 cm, 138 kg and body mass index 53.1) who had an elective laparoscopic cholecystectomy. The dose of induction agent was determined by lean body mass estimated by BIA, and the sedation was assessed by the observer's assessment alertness/sedation scale. Conclusions: Dose determination through lean body mass measured by BIA is useful in highly obese patients.
