title: Hemodynamic response of elderly patients undergoing major surgery under moderate normovolemic hemodilution.
abstract: Moderate normovolemic hemodilution (MNH) is used in general surgery not only when major blood loss is anticipated but also as a prophylactic measure for the prevention of postoperative deep vein thrombosis. The hemodynamic effects of MNH (hematocrit value 27-29%) with dextran 70 as diluent were evaluated in 50 patients undergoing major surgery (cholecystectomy or total hip arthroplasty). They were divided into two groups according to age: I less than 60; II greater than 60 years. Comparison of the results obtained in the two groups shows no significant difference between them, either before or after hemodilution. Our study shows that MNH is a safe procedure, not only in young patients but also in those over 60 years.
