[A modified technic of preoperative acute normovolemic hemodilution--the advantages and economic effect of its use in planned colorectal surgery]

Abstract

In a prospective and comparative study were included 129 patients undergone planned operation for colorectal cancer. They were divided in two randomized groups: Group A consisted of 65 patients operated under conditions of preoperative acute normovolemic hemodilution (PANHD) by an own modified technique with Ringer-lactate and hemodex. Group B (control) included 64 patients operated with the use of homologous blood substitution. The results in the two groups were compared as to: intra- and postoperative blood transfusions; time (in days) of postoperative treatment; number of postoperative complications. Statistically significant differences (p less than 0.001) referrable to all three compared values were found. The modified PANHD technique in planned colorectal surgery is safer for the patients than the so far suggested techniques and may readily gain acceptance with the use of solutions of domestic produce. It leads to significant decrease in homologous blood transfusion, shortening the postoperative stay in hospital of patients subjected to hemodilution. The number of patients in whom postoperative complications developed was reduced.
