摘 要 目的:對比无创呼吸机不同模式治疗慢性阻塞性肺疾病(COPD)合并Ⅱ型呼吸衰竭(RF)的效果。方法:将行无创正压机械通气(NIPPV)治疗的100例COPD合并Ⅱ型RF患者,依据随机数字表法分为A、B两组各50例。A组采用无创呼吸机自主呼吸和时间控制(ST)模式,B组采用无创呼吸机平均容积保证压力支持(AVAPS)模式。比较两组血气指标、呼吸力学指标、呼吸同步性指标、慢性阻塞性肺疾病评估测试(CAT)评分及不良反应发生情况。结果:治疗后,B组动脉血酸碱度(pH)、经皮血氧饱和度(SPO2)、动脉血氧分压(PaO2)、潮气量(TV)、每分钟通气量(MV)、平均吸气同步率及平均呼气同步率水平较A组高,动脉血二氧化碳分压(PaCO2)、呼吸频率(RR)、吸气时间分数(Ti/ Ttot)水平、CAT评分及不良反应发生率较A组低(均P<0.05)。结论:无创呼吸机AVAPS模式对COPD合并Ⅱ型RF患者血气指标、呼吸力学指标、疾病症状及呼吸机同步性指标的改善效果均优于ST模式,且不良反应较少。

ABSTRACT Objective: To compare the efficacy of the use of different modes of non-invasive respirator in the treatment of chronic obstructive pulmonary disease (COPD) with type II respiratory failure (RF). Methods: One hundred patients with COPD and type II RF treated by non-invasive positive pressure mechanical ventilation (NIPPV) were randomly divided into group A and B with 50 cases each. A non-invasive respirator for spontaneous breathing and time control (ST) mode was adopted in group A, while a non-invasive respirator mean volume guaranteed pressure support (AVAPS) mode in group B. Blood gas index, respiratory mechanics index, respiratory synchronicity index, COPD assessment test (CAT) score and the incidence of adverse reactions were compared between the two groups. Results: After treatment, the pH value of arterial blood, the levels of percutaneous oxygen saturation (SpO2), arterial oxygen partial pressure (PaO2), tidal volume (TV), minute ventilation volume(MV), mean inspiratory synchrony rate and mean expiratory synchrony rate were higher, but the levels of arterial blood carbon dioxide partial pressure (PaCO2), respiratory rate (RR), inspiratory time fraction (Ti/Ttot), CAT score and the incidence of adverse reactions were lower in group B than group A (all P<0.05). Conclusion: Non-invasive respirator AVAPS mode can improve blood gas index, respiratory mechanics index, disease symptom and respirator synchrony index and is better than ST mode.

Ⅱ型呼吸衰竭(respiratory failure, RF)为慢性阻塞性肺疾病(chronic obstructive pulmoriary disease, COPD)病情进展常见并发症,既往临床治疗COPD合并Ⅱ型RF多以抗感染、平喘止咳、低流量鼻导管给氧为主,可在一定程度上改善患者临床症状,但仍有部分患者疗效欠佳。研究表明,有创机械通气治疗COPD合并Ⅱ型RF患者的效果较为显著,可帮助患者维持呼吸,但该疗法为有创方式,对机体创伤较大,易增加呼吸机相关肺炎等并发症发生风险,且长期使用可增加患者依赖性,致使临床脱机难度较大[1]。……
