无创正压通气治疗老年性早期肺性脑病疗效分析

目的: 评价应用双水平正压通气(BiPAP)呼吸机治疗老年性早期肺性脑病的疗效。方法: 分通气组和对照组,对照组给予常规抗感染、祛痰、平喘、低浓度持续吸氧等治疗。通气组除常规治疗外,加用BiPAP呼吸机治疗,选择合适鼻罩,设定参数S/T模式;呼吸频率16次/分,呼气压3~4 cmH₂O,吸气压增大至10~15 cmH₂O,通气时间3~5天,每天2次,每次4 h。结果: BiPAP呼吸机的治疗成功率93.3%。加用BiPA P呼吸机治疗可明显减轻呼吸肌疲劳,使呼吸频率和心率减慢,改善呼吸困难。结论: 鼻罩BiPAP呼吸机对老年性COPD合并早期肺性脑病患者疗效较好,可减少气管插管和气管切开所致的并发症发生率,减轻患者痛苦,降低医疗费用,缩短住院时间。

Noninvasive mechanical ventilation for early pulmonary encephalopathy in the elderly

Objective:To evaluate the curative effect of BiPAP ventilar in treatment of chronic obstructive pulmonary disease(COPD) with early pulmonary encephalopathy in the elderly.Methods:Sixty cases were divided into aeration group and control group.The control group received treatment of anti-infection,eliminating phlegm,relieving asthma and continuously inhaling low concentration oxygen.The aeration group were given BiPAP respirometer in addition to the above routine therapy.The respirometer parameter was S/T model.The respiratory frequency was 16/min,EPAP 3 to 4 cmH 2O,IPAP 4 to 6 cmH 2O,then rising to 10 to 15 cmH 2O;the aeration duration was 3 to 5 days,2 times per day,4 hours per time.Results:Routine treatment combined with BiPAP respirometer improved PaO 2,relieved the respiratory muscle fatigue,and reduced the heart rate and respiratory frequency.The available rate of BiPAP was 93.3%.Conclusions:BiPAP ventilator is effective for treatment of COPD with early pulmonary encephalopathy in the elderly.It can avoid trachea incubation penditure,decrease the incidence of complication,shorten the time of hospitalization and reduce the medical expenses.
