摘要 目的探讨温度分别为37℃、22℃、15℃的CO2气腹,对腹腔镜下前列腺癌根治术患者动脉血pH、二氧化碳分压[p(CO2)]的影响。方法将71例前列腺癌患者随机分为37℃的CO2气腹组(37℃组)、22℃的CO2气腹组(22℃组)、15℃的CO2气腹组(15℃组),37℃组23例患者,22℃组22例患者,15℃组26例患者。测量3组患者腹腔镜下前列腺癌根治术患者手术中10 min、30 min、60 min动脉血pH、p(CO2)的变化情况。结果在腹腔充气后,各组组内在3个时间点的pH、p(CO2)结果比较表明,动脉血pH逐渐降低,p(CO2)逐渐升高(P<0.01)。在术中60 min时,pH值下降幅度最小且p(CO2)升高最少的是15℃组(P<0.01),该组的pH、p(CO2)分别为(7.38±0.05)、(42.54±2.31);pH值下降幅度最大且p(CO2)升高最多的是37℃组(P<0.01),其pH、p(CO2)分别为(7.33±0.03)、(47.43±2.64)。结论腹腔镜下前列腺癌根治术中,CO2气腹的温度在一定范围内温度越高,患者动脉血中的pH值下降得越多,且p(CO2)升高得也越多;而温度越低则患者动脉血中的pH值下降越少、p(CO2)升高得也越少。CO2气腹的温度在预防患者术中、术后发生酸中毒和高碳酸血症有积极的作用,对手术室的护理有重要指导意义。
