[摘要] 目的 分析不同腹腔压在呼吸衰竭及其对神经调节辅助通气膈肌电活动(EADi)和呼吸功能的影响。 方法 选取2015年1月~2016年1月50例医院收治呼吸衰竭患者作为观察对象,所有患者均采用神经调节辅助通气,根据国际腹间隙综合征学会对高腹腔压(腹腔压≥12 mmHg)的定义将患者分为高腹压组和非高腹压组。观察两组患者的每小时EADi值与潮气量。 结果 高腹压组EADi值方面均显著低于非高腹压组(P<0.05),而在潮气量方面则显著高于非高腹压组(P<0.05)。 结论 在应用神经调节辅助通气时,高腹腔压会使得EADi值下降而潮气量升高;非高腹压时则会使得EADi值升高而潮气量下降。

[Abstract] Objective To investigate the effects of different abdominal pressure on respiratory failure and its effect on the neurally adjusted assisted ventilation diaphragm electrical activity(EADi) and respiratory function. Methods 50 patients with respiratory failure who were admitted to our hospital from January 2015 to January 2016 were selected as the observation subjects. All patients were given neurally adjusted assisted ventilation. According to the definition of high abdominal pressure(intraperitoneal pressure≥12 mmHg)by the International Abdominal Compartment Syndrome Association, the patients were divided into high abdominal pressure group and non-high abdominal pressure group. The EADi values and tidal volume per hour were observed in both groups. Results The EADi values in the high abdominal pressure group were significantly lower than those in the non-high abdominal pressure group(P<0.05), but the tidal volume was significantly higher than that in the non-high abdominal pressure group(P<0.05). Conclusion In the application of neurally adjusted assisted ventilation, high abdominal pressure makes the EADi value decreased and tidal volume increased; non-high abdominal pressure makes the EADi value increased and tidal volume decreased.

機械通气作为临床维持患者呼吸功能的重要方法之一,对于临床抢救和生命维持具有重要作用[1]。随着临床医学水平的不断提升,机械通气模式得到迅速发展,尤其是改善气体交换、减少呼吸机相关肺疾病发生率等方面,为提升患者的存活率作出了较大的贡献[2,3]。但是其也可能会造成气压伤等并发症[4]。神经调节辅助通气作为如今临床医学中应用的新型通气模式,与传统通气存在较大的差异,其通气量主要是根据患者的实际需求进行调整的,每次通气量都能够符合患者的通气需求[5]。因此,文章主要针对不同腹腔压在呼吸衰竭及其对神经调节辅助通气膈肌电活动(EADi)和呼吸功能的影响展开分析,现报道如下。
