Abstract
We studied the influence of perfusion temperature during extracorporeal circulation (ECC). 44 adult consecutive patients who underwent CABO were divided into two groups. One group received 35°Csystemic perfusion (35°C group, n=22) and another group received 32°C systemic perfusion (32°C group, n=22). There were no differences between both groups in the preoperative data. There were no hospital death and cerebral complications in both groups. ECC time and aortic cross-clamp time were not different between both groups. Blood loss after operation was not different between both groups. 35°C group needed significantly lower dose of dopamine at 1CU admission than 32 °C group. Postoperative cardiac index, mean arterial pressure and systemic vascular resistance were not different between both groups. PaO2 at ICU admission in group 35°C tended to he higher than that in group 32°C . Serum CK and OPT levels at ICU admission were significantly lower in 35 °C group. WBC counts at l and 2POD were also significantly lower in 35°C group. We concluded that normothermic(35°C) ECC was safe and useful management.
