摘　　要：本文通过对腹腔镜检 CO_2气腹后的118例和71例分别进行心电图描记和动脉血气分析,以观察大量 CO_2进入腹腔后对机体的影响。结果表明,腹腔镜检 CO_2气暖后,对心脏功能有一定的影响,主要表现为 T 波改变及窦性心律失常。T 波改变术前发现率为1.69%,术后发生率为15.25%,P<0.01,有显著差异。窦性心率不齐镜检前后分别为7.62%及19.49%,窦性心动过速腹腔充气前占1.69%,充气后增至8.47%,其变化是明显的。室性心动过缓也有发现,但无室性纤颤等严重心律失常发生。动脉血 pH值气腹前后变化差异显著(P<0.05).PaCO_2无明显差异(P>0.05),但部分总者 CO_2分压仍高于气腹前1.33kPa,BE 值变化明显.P<0.01.pH 值偏酸,可能与术中常规输林格氏液有关。Electrocardiogram was performed in 118 patients and blood gas analysis was done in 71 patients who were undergoing laparoscopic surgery to investigate the effects of pneumoperitoneum with carbon dioxide. Results showed that cardiac function was affected to some extent as manifested by change in T waveform and sinus arrhythmia.The incidence of T waveform change was 1.69% before operation and was 15.9.5% after the pneumoperitoneum(P<0.01).Incidences of sinus arrhythmia were 7.62% and 19.49% respective- ly.Incidences of sinus tachycardia were 1.69% and 8.47% respectively,pH value was significantly higer before the operation than after the pneumoperitoneum (P<0.05),which might be caused by the routine in- fusion of Ringer's solution.There were no marked changes in PaCO_2 and BE.
