腹部外科患者术后肺功能的变化

目的：探讨腹部外科手术对肺功能的影响。方法：应用床旁肺功能仪及血气分析仪对３５例腹部外科患者（腹腔感染组１６例，择期手术组１９例）于术前、术后的用力肺活量９ＦＶＣ）、第１秒时间肺活量比（ＥＶ １．０％）、动脉血氧分压（ＰａＯ２）、动脉血二氧化碳分压（ＰａＯ２） 、血氧饱和度（ＳａＯ２）等肺功能指标进行监测。结果：择期手 术后１天、３天ＦＶＣ、ＰａＯ２较术前明显降低（Ｐ〈０．０５），术后５天基本恢复正

Changes of Pulmonary Function after Abdominal Surgery

Objective:To prospectively evaluate the influences of abdominal surgery on postoperative pulmonary function. Methods: Pre- and post- operative pulmonary function indexes,such as forced vital capacity (FVC) ,forced expiratory rate in the first second (FEV 1.0%), arterial O2 pressure (Pa O2 ), arterial CO2 pressure (Pa CO2 ) and oxygen saturation of blood (Sa O2) , were measured on 35 abdominal surgery patients. Results: FVC and Pa O2 decreased significantly on postoperative day (POD)1 ,3 (P<0.05) and returned to normal levels on POD 5,FEV 1 .0% ,SaO2 and Pa CO2 decreased slightly but not significant. Qmclusion:The patients who received selective operation appeared restrictive ventilation disturbance,mean-while the patients who suffered from peritonitis had both restrictive ventilation and aeration disturbances.
