Efficacy of Preemptive Volume Loading to Prevent Arterial Hypotension During Induction of General Anesthesia
- Registration Number
- NCT01594021
- Lead Sponsor
- Hopital Foch
- Brief Summary
Induction of general anesthesia induces frequently arterial hypotension. The short term goal of this study is to evaluate if preemptive volume loading prevents such complication.
- Detailed Description
This is a randomized, prospective study which will include a total of 200 patients who are scheduled to undergo elective surgery. The research participants will be randomly assigned to
* a control group that will receive a low preemptive volume loading (50 mL of gelatin),
* a protocol group that will receive a high preemptive volume loading (500 mL of gelatin).
Volume loading is preceded by the measurement of stroke volume and cardiac output before and after a passive leg elevation test and followed by a standardized anesthetic protocol.
