Administering propofol intravenously adequately during induction of general anesthesia implies a good knowledge of pharmacokinetics and pharmacodynamics, a good understanding of how anesthesia alters consciousness and the ability to correctly interpret vital signs monitoring. The purpose of this study was to assess the usual practice of anesthesiologists in Portugal regarding the administration of propofol during the induction of general anesthesia. A transversal observational analytical and descriptive study, conducted through a questionnaire sent by e-mail to all anesthesiologists of several Portuguese hospitals. The questionnaire presented a conventional scenario (male subject, 50 years, 60 kg, 160cm, ASA I, submitted to general anesthesia with 1% propofol) and has 10 questions directed to the administration of propofol during induction phase of general anesthesia. A descriptive analysis of the data was performed through SPSS 23.0®. A total of 118 physicians responded to the survey, most of whom were experts for more than 5 years (56.9%). Based on the presented scenario, most anesthesiologists would administer a propofol dose of 60 mg at induction, at a rate greater than 1200mL/hours, and would assess loss of consciousness by evaluating loss of the eyelid reflex, which, in BIS index, would be reflected in a 60 value. Most participants measure the patient's blood pressure every 5 minutes and have never used target-controlled infusion systems.
