长期机械通气并发症及预后探讨

Complications and prognosis of long-term mechanical ventilation

目的探讨长期机械通气>1月的患者并发症及预后情况。方法对在我院ICU救治的18例长期机械通气(>1月)患者进行回顾性分析,将其血浆白蛋白水平、血红蛋白水平、血气分析与对照组(机械通气时间为≤1月,≥7天)患者进行分析。结果机械通气时间>1月的患者与对照组相比,血浆白蛋白水平明显下降(P<0.05〕,但是血红蛋白水平、血气分析无统计学意义,死亡率为83.3%,死亡原因为呼吸衰竭的仅4例。结论机械通气的并发症是造成患者死亡的主要原因,护理、参数调节、营养支持是治疗成功关键。

Objective To study the complication and prognosis in the patients with the long - term mechanical ventilation （more than one month）. Methods 18 patients were rolled in. To retrospective study the patients with the long - term mechanical ventilation （ more than one month） in RCU. And investigate the influential factors as Serum albumin levels, hemoglobin levels, blood gas with the control group （ mechanical ventilation for less than one month, more than seven days） . Results The results of mechanical ventilation time more than one month of patients compared with the control group was Serum albumin levels decreased significantly （ P 〈 0.05 ） , but the level of hemoglobin, the blood gas analysis were no statistical significance. Mortality rate was 83.3%. The cause of death was respiratory failure only four cases. Conclusion The complications of the mechanical ventilation were the leading cause of death in patients of the long-term mechanical ventilation. Nursing, parameter adjustment, nutrition support are the key to success.
