【摘要】 目的 探討血浆氨基末端脑钠肽前体(NT-proBNP)对慢性阻塞性肺疾病急性加重(AECOPD)机械通气撤机的指导意义, 为临床提高AECOPD 患者的抢救成功率提供依据。方法 60例AECOPD行有创机械通气患者, 按照撤机成功与否分为成功组(34例)和失败组(26例)。观察对比两组患者血浆NT-proBNP水平、肺的顺应性情况及两组患者脱机前的肺通气情况。结果 两组患者脱机前氧分压、急性生理学与慢性健康状况评分Ⅱ(APACHEⅡ)评分比较, 差异均无统计学意义(t=0.942、0.080, P>0.05);成功组脱机前二氧化碳分压低于失败组, 机械通气时间短于失败组, 差异具有统计学意义(t=4.971、5.955, P<0.05) 。成功组患者血浆NT-proBNP为(1429.32±201.37)pg/ml, 显著高于失败组的(890.21±106.37)pg/ml, 肺顺应性为(63.09±8.71) ml/cm H2O, 显著优于对照组的(51.62±7.41)ml/cm H2O, 差异均具有统计学意义 (P<0.05)。结论 NT-proBNP对AECOPD机械通气撤机有指导意义, 临床医师可根据患者血浆NT-proBNP的水平对患者进行适时的撤机, 以提高撤机成功率。

【Abstract】 Objective To explore guiding significance of N-terminal pro-brain natriuretic peptide (NT-proBNP) for mechanical ventilation withdrawal in acute exacerabation of chronic obstructive pulmonary disease (AECOPD), to provide basis for increasing clinical rescue success rate in AECOPD patients. Methods A total of 60 AECOPD patient performing mechanical ventilation withdrawal were divided by successful withdrawal or not into successful group (34 cases) and failure group (26 cases). Observation and comparison were made on serum NT-proBNP level, compliance of lung and lung ventilation before offline in two groups. Results There were no statistically significant difference in oxygen partial pressure, acute physiology and chronic health evaluationⅡ(APACHEⅡ) before offline in two groups (t=0.942, 0.080, P>0.05). The successful group had lower oxygen partial pressure than the failure group, and shorter mechanical ventilation time than the failure group. Their differences had statistical significance (t=4.971, 5.955, P<0.05). The successful group had higher serum NT-proBNP as (1429.32±201.37) pg/ml than (890.21±106.37) pg/ml in the failure group, better compliance of lung as (63.09±8.71) ml/cm H2O than (51.62±7.41) ml/cm H2O in the failure group. Their differences had statistical significance (P<0.05). Conclusion NT-proBNP provides guiding significance for mechanical ventilation withdrawal in AECOPD, and Clinicians can timely withdraw machine of patients according to the level of plasma NT-proBNP in patients, in order to improve the success rate of withdrawal.

随着全球气候的改变, 目前呼吸道疾病已成为住院和门诊发病率较高的疾病之一, 对于呼吸系统疾病的治疗, 如慢性阻塞性肺疾病、呼吸衰竭等, 均采用机械通气进行治疗, 而研究证明时撤机失败的一个被重视的原因, 患者常因撤机的时间不对, 导致治疗的失败[1]。血浆NT-proBNP是常使用的用于反映心功能的重要血液指标, 且多数临床医师在思考是否可以将NT-proBNP 作为撤机结局的预测指标值得思考[2-4]。本组研究旨在进一步探讨NT-proBNP对AECOPD撤机的指导意义, 现将结果报告如下。
1 资料与方法
1. 1 一般资料 选取本院重症加强护理病房(ICU) 2013年10月~2016年12月诊断为AECOPD并行有创机械通气的60例患者进行研究, 所有患者均符合AECOPD的诊断标准, 按照患者机械通气后撤机的成功与否分为成功组(34例)和失败组(26例)。其……
