[摘要] 目的 分析不同腹腔壓在呼吸衰竭及其對(duì)神經(jīng)調(diào)節(jié)輔助通氣膈肌電活動(dòng)(EADi)和呼吸功能的影響。 方法 選取2015年1月~2016年1月50例醫(yī)院收治呼吸衰竭患者作為觀察對(duì)象,所有患者均采用神經(jīng)調(diào)節(jié)輔助通氣,根據(jù)國(guó)際腹間隙綜合征學(xué)會(huì)對(duì)高腹腔壓(腹腔壓≥12 mmHg)的定義將患者分為高腹壓組和非高腹壓組。觀察兩組患者的每小時(shí)EADi值與潮氣量。 結(jié)果 高腹壓組EADi值方面均顯著低于非高腹壓組(P<0.05),而在潮氣量方面則顯著高于非高腹壓組(P<0.05)。 結(jié)論 在應(yīng)用神經(jīng)調(diào)節(jié)輔助通氣時(shí),高腹腔壓會(huì)使得EADi值下降而潮氣量升高;非高腹壓時(shí)則會(huì)使得EADi值升高而潮氣量下降。

[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(jī)械通氣作為臨床維持患者呼吸功能的重要方法之一,對(duì)于臨床搶救和生命維持具有重要作用[1]。隨著臨床醫(yī)學(xué)水平的不斷提升,機(jī)械通氣模式得到迅速發(fā)展,尤其是改善氣體交換、減少呼吸機(jī)相關(guān)肺疾病發(fā)生率等方面,為提升患者的存活率作出了較大的貢獻(xiàn)[2,3]。但是其也可能會(huì)造成氣壓傷等并發(fā)癥[4]。神經(jīng)調(diào)節(jié)輔助通氣作為如今臨床醫(yī)學(xué)中應(yīng)用的新型通氣模式,與傳統(tǒng)通氣存在較大的差異,其通氣量主要是根據(jù)患者的實(shí)際需求進(jìn)行調(diào)整的,每次通氣量都能夠符合患者的通氣需求[5]。因此,文章主要針對(duì)不同腹腔壓在呼吸衰竭及其對(duì)神經(jīng)調(diào)節(jié)輔助通氣膈肌電活動(dòng)(EADi)和呼吸功能的影響展開分析,現(xiàn)報(bào)道如下。
