Canada60 participantsStarted 2020-10-26

Plain-language summary

The purpose of this prospective randomized controlled study is to compare the efficiency in preventing perioperative hypothermia of a continuous active prewarming combined with active intraoperative warming versus passive prewarming plus intraoperative warming for short outpatient surgery.

Inclusion Criteria: * ASA Physical Status I to III * Elective Outpatient Surgery under General Anesthesia * Surgery Length from 30 to 120 minutes (from induction of anesthesia to extubation) Exclusion Criteria: * Patient refusal or inability to consent * Neuraxial (spinal or epidural) anesthesia * BMI over 40 (Flex gown limitation) * Pregnancy * Active infection * Systemic disease which impairs thermoregulation (hypothyroidism or hyperthyroidism, adrenal insufficiency, major burns, para / quadriplegia) * Medications affecting core body temperature (like levothyroxine) * Facial surgery * Use of a fluid warmer

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring

Temperature at the end of surgery (°Celsius)

Timeframe: Measure taken at the end of surgery, before the patient leaves the operating room for the recovery room (below 120 minutes)
