Hemodynamic assessment of extracorporeal circulation in normothermia and hypothermia in pediatric cardiovascular surgery

Abstract:

Hypothermia during the extracorporeal circulation is a common method in pediatric cardiovascular surgery. The normothermia was started by Lecompte in 1995. A randomized and prospective study was conducted in 100 children aged over 30 days to assess the hemodynamic changes in normothermia and hypothermia. In normothermia a temperature of 36 ºC, hematocrit higher than 30% and a flow between 2, 8 and 3, 5 liter/min/m2 were used. In hypothermia, hematocrit between 24 and 30% and a flow between 2, 4 and 2, 8 liters/min/m2. In normothermia extracorporeal circulation time and values of lactic acid were very lower, whereas the central venous saturation was higher at the end of extracorporeal one and at 6 hours in intensive therapy. In normothermia heart rate was higher at 6 hours and the rates of inotropics rates were lower at 24 hours. Normothermia protects the organs in a safe and effective way.
