摘要 目的:观察猪全身麻醉开腹手术中采取保温措施对保温措施对猪生理参数的影响。方法:选取进行胆管损伤修复手术的实验猪30例,随机分为保温组15例和对照组15例。保温组术中静脉输入温度为接近受试猪体温的38.5~39.5X2的温热液体,并采用温度为39℃的恒温冲洗液进行术区冲洗;对照组术中静脉输入常温(20-22℃)液体,并用同温度的冲洗液进行术区冲洗。观察受试猪术中体温、心率在麻醉诱导后、术中30min、术中60min、术中90min、术毕五个观察时相变化(T1、T2、T3、T4、T5);拔管时间以及凝血酶原时间(PT)、活化部分凝血活酶时间(APTT)、凝血酶时间(TT)、纤维蛋白原(FIB)在术前和术后的值。结果:保温组与对照组在麻醉诱导以及手术过程中后核心体温比较无显著性差异(P〉0.05);在术中30min、60min、90min及术毕即刻,保温组的核心体温均高于对照组(P〈0.05)。保温组与对照组在麻醉诱导后(T1)的心率(HR)比较无显著性差异(P〉0.05);T2、T3、T4、T5,保温组的心率均低于对照组(P〈0.05)。对照组受试猪的拔管时间明显长于保温组,(p〈0.05)。术后保温组与对照组之间PT、APTT、TT、FIB比较差异显著(P〈0.05)。结论:手术过程中采取保温措施可以减少受试动物体温下降和低体温的发生,保障机体循环功能的稳定,减少出血量,缩短术后恢复和拔管的时间。
