【摘要】 目的:探讨儿童腹腔镜阑尾切除术(LA)CO2气腹对呼吸的影响。方法:47例小儿行LA,观察气腹前后PETCO2、SpO2、Ppeak的变化。结果:气腹后比气腹前患儿SpO2下降;而Ppeak、PETCO2上升。放气后PETCO2、SpO2、Ppeak基本恢复至气腹前水平。PETCO2气腹前后有显著差异,术终拔管前降至近气腹前水平。无低氧血症发生。结论:加强呼吸循环监测,术中合理用药,能使腹腔镜手术麻醉顺利完成,儿童腹腔镜手术将更安全可靠。更多还原

【Abstract】 Objective:To investigate the effect of CO₂ pneumoperitoneum on respiration in child laparoscopic appendectomy（LA）.Methods:The P_ETCO₂,SpO₂ and Ppeak before and after pneumoperitoneum of 47 children undergoing LA were compared.Results:SpO₂ decreased after pneumoperitoneum as compared with that before pneumoperitoneum,while Ppeak and P_ETCO₂ increased.After deflation,P_ETCO₂,SpO₂ and Ppeak generally recovered to the level before pneumoperitoneum.The level of P_ET CO₂ was significantly different before and after pneumoperitoneum,and it went down to the level before pneumoperitoneum before drawing the tube at the end of the operation.No hyoxemia occurred.Conclusions:Strentreing the respiratory and circulatory moritoning and paying attention to rational use of drug,anesthesia in LA will be more successfully and safely.更多还原
