腹腔镜不同气腹压力对新生儿及婴儿呼吸功能的影响

Respiratory function changes in different CO_2 pneumoperitoneum pressure in neonates and younger infants undergoing laparoscopy

目的探讨新生儿及婴儿腹腔镜手术中不同CO2气腹压力对患儿呼吸功能的影响。方法 20例腹腔镜手术患儿在全麻下,分别予以5 mmHg和10 mmHg气腹压力建立人工CO2气腹,并记录0、5、10 mmHg气腹压下呼吸功能指标的变化。结果气腹后患儿呼气末CO2分压明显增高,潮气量及肺顺应性明显降低;并且随着气腹压的增高,呼气末CO2分压也逐渐增高,潮气量及肺顺应性逐渐降低,但血氧饱和度在气腹前后无明显变化。结论腹腔镜手术时在满足手术操作空间需要的前提下,应尽量降低气腹压力以减少对患儿呼吸功能的影响。

Objective To observe respiratory function changes in different CO2 pneumoperitoneum pressure in neo- nates and younger infants undergoing laparoscopy. Methods Twenty patients with laparoscopy were performed under gen- eral anesthesia. Artificial artificial CO2 pneumoperitoneum was established by giving 5 mmHg and 10 mmHg pneumoperito- neum pressure. Respiratory data were measured in different CO2 pneumoperitoneum pressure （0 mmHg, 5 mmHg and 10 mmHg）. Results PETCO2 was significantly increased with increasing of pneumoperitoneum pressure after peritoneal insuf- flation, VT and PC were reduced significantly, but SPO2 was not changed significantly. Conclusions During the time of laparoscopic operation, pneumoperitoneum pressure should be decreased to iessen the influence on the respiratory function of neonates and younger infants patients.
