腹腔镜不同气腹压力对新生儿及小婴儿循环功能的影响

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

目的:探讨新生儿及小婴儿腹腔镜手术中,不同CO2气腹压力对循环功能的影响。方法:20例腹腔镜手术患儿在全麻下,分别予以5mmHg和10mmHg气腹压力建立人工CO2气腹,并记录0、5和10mmHg气腹压下循环动力学指标。结果:气腹后患儿心率、平均动脉压明显增高,并且随着气腹压的增高,心率、平均动脉也逐渐增高,但血氧饱和度数值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,尽量降低气腹压力以减少对患儿循环功能的影响。

Objective： To observe circulatory function changes in different CO2 pneumoperitoneum pressure in neonates and younger infants undergoing laparoscopy.Methods： Twenty patients with laparoscopy were performed under general anesthesia.Hemodynamic data were measured in different co2 pneumoperitoneum pressure（0mmHg,5mmHg and 10mmHg）.Results： HR and MAP were significantly increased with increasing of pneumoperitoneum pressure after peritoneal insufflation,and SPO2 was not changed significantly.Conclusion： Lower pneumoperitoneum pressure should be used in neonates and younger infants undergoing laparoscopy.The lower pneumoperitoneum pressure be chosed,the little influence circulatory function more little.
