intravenous administration
Active Comparator: Low pre-emptive volume loading Drug: Gelatin 50 mL
intravenous administration

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.


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Adult patients undergoing elective surgery.

Exclusion Criteria:

  • Difficult peripheral venous access
  • Allergy to gelatin
  • Symptomatic cardiac disease, rhythm trouble, pace-maker, aortic valvular disease, aortic disease
  • Morbid obesity, low BMI,
  • hypovolemia,
  • Raynaud syndrome or scleroderma,
  • Contra-indication to propofol, remifentanil or to the use of Bispectral Index,
  • Hematocrit < 20%.
