摘要
目的观察过度通气在腹腔镜手术中的应用，减少高碳酸血症的发生，减轻患者术后不适。方法妇科腹腔镜手术60例，外科腹腔镜手术60例，泌尿外科腹腔镜手术30例，随机分成两组。A组：术中呼吸参数不变；B组：根据呼气末CO2分压（PETCO2）运用过度通气。监测两组PETCO2、气道压（Paw）。结果两组患者气腹后PETCO2与Paw都较气腹前高，但A纽PETCO2与Paw升高更明显；B组PETCO2基本维持在正常范围内。两组同时点比较差异有统计学意义（P〈0．01）。结论过度通气在腹腔镜手术中的应用，可以减少发生高碳酸血症的危险，大大减轻了腹腔镜CO2气腹术后患者不适。
Objective To observe the effect of using hypervwentilation on PETCO2 of gynecological laparoscopic surgical patients after - carbon dioxide pneumoperitonem. Methods 150 cases were randomly divided into two groups. Group A：maintaining a fixed respiratory parameter in the whole operation. Group B：using hyperventilation according to PETCO2. At the same time, PETCO2 ,Paw of all patients were detected. Results In two groups PETCO2 after carbon dioxide pneumoperitoneum were significantly higher than PETCO2before pneumoperitoneum. But in group A PETCO2 was above the normal rang. Furthermore, after pneumoperitoneum, PETCO2 in group A were significantly higher than that in group B. It was the same in Paw. Conclusion Hypcrventilation could cause PETCO2 step - up, and it could be decreased. Meanwhile, it could reduce the possibility of hypercapnia.
