Comparison of the Hemodynamic Effect of Three Positions During Induction of Anesthesia

Egypt123 participantsStarted 2019-07

Plain-language summary

The most common methods for prevention of post-induction hypotension are preoperative fluid loading and vasopressors. Leg elevation induces an intrinsic transfusion of 150 mL blood from the lower limbs to the central fluid compartment. Leg elevation was previously reported by our group to decrease the incidence of maternal hypotension after spinal anesthesia for caesarean delivery. Passive leg raising was also reported to provide a stable hemodynamic profile during induction of anesthesia for cardiac surgery. Head-down position was previously reported as a useful measure for management of hypovolemia in various patient groups. No studies to the best of our knowledge had evaluated the compare both positions (leg elevation position and head-down position) during induction of anesthesia in non-cardiac surgery

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * adult patients (18-60 years), american society of anesthesiologist physical status I-II, scheduled for elective non-cardiac surgery under general anesthesia Exclusion Criteria: * Patients with cardiac morbidities (impaired contractility with ejection fraction \< 50%, heart block, arrhythmias, tight valvular lesions), patients on antihypertensive medications, and patients with uncontrolled hypertension will be excluded from the study. Patient with decompensated respiratory disease (poor functional capacity, generalized wheezes, peripheral O2 saturation \< 90% on room air), patients at increased risk of aspiration (Inadequate fasting time, chronic renal failure, diabetes mellitus, BMI≥40 kg/m2, Gastroesophageal reflux disease, Gastrointestinal obstruction, Previous upper gastrointestinal surgery and/or undergoing Upper gastrointestinal surgery), pregnant patients and patients with increased intracranial tension will be also excluded from the study

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.
