应用机械通气模式改善婴幼儿心脏手术后低氧血症的护理

目的研究应用压力控制型同步间歇指令（SIMV＋PC）加压力支持（PSV）加呼气末正压（PEEP）通气模式改善婴幼儿心脏手术后并发低氧血症的护理方法。方法对62例心脏手术后并发低氧血症患儿分为治疗组和对照组，治疗组（32例）给予SIMV（PC）＋PSV＋PEEP通气，随时调整呼吸机参数，加强呼吸道的护理。对照组（30例）采用同步间歇指令（SIMV）通气模式和常规护理。结果治疗组血氧改善快，呼吸机使用时间短，并发症少；住ICU时间缩短。治疗组1例、对照组3例死于多器官功能衰竭。结论婴幼儿心脏手术后并发低氧血症时，应用SIMV（PC）＋PSV＋PEEP模式通气，能有效改善低氧血症，减少肺部并发症，缩短呼吸机使用时间。

Nursing countermeasure on application of SIMV (PC) + PSV + PEEP to improve hypoxemia after infant cardiac operation

Objective To research nursing methods on application of SIMV (PC) + PSV + PEEP ventilation mode to improve hypoxemia after infant cardiac operation. Methods 62 infants with hypoxemia undergoing cardiac operation were divided into two groups randomly. The 32 infants in treat group were given SIMV (PC) + PSV + PEEP ventilation mode, while, 30 infants in control group were given SIMV ventilation mode. Both groups were given routine nursing. Results Hypoxemia was improved faster;complication was fewer;time of using respirator and stays in the intensive care unit were shorter in treat group than control group.58 subjects were discharged from hospital after recovery while 4 subjects (lcase in treat group and 3 cases in control group) died from multiple organ failure. Conclusions When hypoxemia occurs after infant cardiac operation, SIMV (PC) + PSV + PEEP ventilation mode can improve hypoxemia effectively, decrease pulmonary complications and shorten time of using respirator.
