【摘要】 目的:探讨EICU机械通气患者应用神经调节辅助通气模式进行撤机的临床效果。方法:将符合撤机标准的62例机械辅助通气患者随机分为NAVA组和PSV组各31例。NAVA组应用神经调节辅助通气(NAVA)模式进行撤机,PSV组应用压力支持通气(PSV)模式进行撤机。比较两组患者撤机成功率、再插管率及有创通气时间。结果:NAVA组成功撤机28例(90.3%),3例(9.7%)再插管继续有创通气;PSV组成功撤机21例(67.7%),9例(29%)再插管继续有创通气;NAVA组有创通气时间4.42±1.03d,PSV组8.21±2.43d。两组撤机成功率、再插管率及有创通气时间比较差异有统计学意义(P<0.05)。结论:采用神经调节辅助通气模式进行撤机,可以提高撤机成功率,缩短机械通气时间。更多还原

【Abstract】 Objective:To investigate the application value of the neurally adjusted ventilation assist in emergency intensive care unit patients with the weaning from mechanical ventilation.Methods:62casess with the mechanical ventilation who up to the standard of ventilator weaning were divided into two groups randomly:31cases with NAVA(Neurally adjusted ventilation assist)and the other 31 cases with PSV(Pressure support ventilation).Then we compared the differences of the success rate of ventilator weaning,reintubation rate and the invasive ventilation time between two groups.Results:Compared to the PSV group,the NAVA group got higher success rate of ventilator weaning(90.3% VS 67.7%),lower reintubation rate(9.7% VS 29%)and less invasive ventilation time(4.42±1.03 dVS 8.21±2.43d).Conclusion:We can get higher success rate of ventilator weaning,lower reintubation rate and less invasive ventilation time with the NAVA in emergency intensive care unit patients with the weaning from mechanical ventilation.更多还原
