Factors Influencing Anesthetic Drug Requirement
Impact of Environmental and Demographic Factors on Pre-operative Doses of Anesthetic Agents (Prospective Multicenter Study)
The main objective of the study is to analyze the influence of several environmental (i.e., timing: seasonal, circadian) and demographic conditions (i.e., age, gender, menstrual cycle) on anesthetic drug requirements (hypnotic and opiate).
