ABSTRACT

The present study tries to demonstrate that the technique of normovolemic haemodilution can be apply in patients undergoing to surgery, these with light or null effects deleterious posquirurgics. In a study of longitudinal, prospective, aleatory and descriptive type 20 patients were studied ASA II-III stable hemodynamic, in two groups of each one that you/they would receive solution colloid or crystalloid respectively. They were determined previous to the beginning of the anesthesia, trans and postanestesic Hb, Hto´s values and arterial, veined gasometrical, as well as registration of vital signs and fibrinogen. A value of Hb was observed Hto post surgical smaller average that the basal one as well as that of fibrinogen, the arterial gasometric showed significant changes in PCO₂, HCO₃ in the period pre and postanestesic. The veined gasometric also showed in the same variable changes significant without ending up being decisive for later behavior, That de TAM showed not very significant changes in the periods pre and postanestesic without ending up leaving the normal parameters. The variable of systolic T/A and diastolic stayed inside normal parameters with slight modifications. You concludes that the haemodilution normovolemic in this type of patients is a sure method, to be applied without important deleterious hemodynamic consequences.
