控制性肺膨胀改善食管癌术后低氧血症病人氧合的疗效探讨

目的观察控制性肺膨胀在食管癌术后防治低氧血症的疗效。方法随机对照设立应用控制性肺膨胀组26例，对照组26例，观察呼吸频率，心率，血氧饱和度和氧分压等氧合指标变化。结果30min后．SaO2从0．90±0．025升高到0．95±0．028，1h后Pa02从10．0±1．66kPa升高到12．1±2．27kPa。24-72h的持续监测SaO2和PaO2亦保持在0．97～0．98和13．1～13．2kPa。与对照组相比，控制性肺膨胀治疗后SaO2和PaO2提高速度快，且能较长时间维持在稳定水平。结论应用控制性肺膨胀能有效防治食管癌术后早期低氧血症病人急性呼吸衰竭的发生。

Study on the effect of sustained inflation on hyoxemia preventing for patient after esophageal operation

Objective To study the effect of sustained inflation （SI） on preventing hyoxemia after the operation of esophageal carcinoma. Method Randomized control clinical trail was approached with the 26 cases in the experimental and control group respectively. Respiratory rate （RR）, heart rate （HR）, arterial blood oxygen saturation （SaO2） and arterial blood oxygen, pressure （PaO2） were measured. Result SaO2 increased markedly from 0. 90±0. 025 to 0.95±0. 028 30 minutes after SI; PaO2 increased significantly from 10.0±1.66 kPa to 12.1±2. 27 kPa 1 h after SI. Continuous monitoring of SaO2 and PaO2 maintain at 0. 969 to 0. 975 and 13.1 to 13.2 kPa 24 h and 72 h after SI. Comparing with control group, Sustained inflation can rapidly improve SaO2 and PaO2 and maintain a steady level for a long time. Conclusion The application of SI after esophageal carcinoma operation can prevent the occurrence of ARDS with the early stage of hyoxemia effectively.
