The haemodynamic adaptation early after aorto-coronary bypass surgery, with special reference to the influence of body temperature on postoperative vasoconstriction, was studied in 20 patients. Cardioplegia arrest was used in all cases. Eleven patients were cooled to 30 degrees C during cardiopulmonary bypass, and nine were normothermic (37.5 degrees C) while the heart was cooled selectively. The normothermic patients had significantly higher oesophageal and skin temperatures in the immediate postoperative period, indicating better heat preservation. However, the systemic vascular resistance was similar in the two groups; i.e. it was moderately elevated initially and subsequently decreased. There was no significant difference regarding postoperative myocardial function. The normothermic patients woke up earlier after the operation than the hypothermic patients, and since they also had a relatively low oxygen uptake index (0.10--0.12 mmol. s-1. m-2), the possibility of earlier extubation in these patients is suggested.
对20例患者进行了研究，观察了主动脉冠状动脉搭桥手术后早期的血流动力学适应情况，特别关注体温对术后血管收缩的影响。所有病例均采用心脏停搏液停搏心脏。11例患者在体外循环期间体温降至30℃，9例患者在心脏选择性降温时体温正常（37.5℃）。体温正常的患者术后即刻食管温度和皮肤温度明显较高，表明保温效果较好。然而，两组的全身血管阻力相似，即最初适度升高，随后下降。术后心肌功能方面无显著差异。体温正常的患者术后苏醒比体温过低的患者早，并且由于他们的氧摄取指数相对较低（0.10--0.12 mmol·s-1·m-2），提示这些患者有可能更早拔除气管插管。
