Efficacy of Preemptive Volume Loading to Prevent Arterial Hypotension During Induction of General Anesthesia

Phase 4

Conditions

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.
