Consort Diagram. Eleven patients consented but were never randomized and not studied: 9: The first author was not available to perform the induction. 1: The case changed from a general anesthetic to a sedation case. 1: The surgeon did not want that patient to be in a clinical study. Five patients were induced and then withdrawn from analysis* because of protocol violations: 1: Airway difficulty during induction. 1: Additional propofol required; 2: Patients received more than 300 mL unwarmed IV fluid. 1: Forced air warming malfunction. *Four patients were withdrawn before T15 so that they had no post-induction temperature measurements. In one patient, there was only one temperature measurement at T15. This patient received more than 300 mL unwarmed IV fluid
