目的评价CPAP-PSV模式与SIMV-PSV-PEEP模式抢救急性发作重度哮喘患者的效果及预后。方法选择88例接受机械通气的急性发作重度哮喘患者,随机分为CPAP-PSV方式机械通气组和SIMV-PSV-PEEP方式机械通气组,观察两组患者撤机前30min和撤机后30min的血气分析,有创通气时间、住重症监护室(RICU)时间、呼吸机相关性肺炎(VAP)发生率、撤机成功率等。结果两种通气模式通气后血气变化差异无显著性,CPAP-PSV组通气指标优于SIMV-PSV-PEEP组,采用CPAP-PSV模式早期上机效果好,且脱机率高,住重症监护室时间短。结论病人急性发作重度哮喘患者达到上机后宜尽早行机械通气,采用CPAP-PSV模式上机效果好、且脱机率高。
Objective To evaluate the efficacy and prognosis of CPAP-PSV and SIMV-PSV-PEEP in the rescue of patients with severe acute asthma. Methods Eighty-eight patients with acute exacerbation of severe asthma undergoing mechanical ventilation were randomly divided into CPAP-PSV mechanical ventilation group and SIMV-PSV-PEEP mechanical ventilation group. Blood gas was observed 30 minutes before weaning and 30 minutes after weaning Analysis, invasive ventilation time, intensive care unit (RICU) time, ventilator-associated pneumonia (VAP) incidence, weaning success rate. Results Compared with SIMV-PSV-PEEP group, CPAP-PSV group had better ventilatory parameters after CPAP-PSV ventilation than CPAP-PSV group. short time. Conclusions Patients with acute exacerbation of severe asthma should get mechanical ventilation as soon as possible after getting on the machine. CPAP-PSV mode has good effect on the machine and high off rate.
