摘要
目的探讨呼吸机通气患者撤机的相关因素及常规撤机指标对撤机的指导意义。方法回顾性分析96例应用机械通气技术的病例,收集各项与撤机相关的因素,并进行统计学分析。结果COPD(慢性阻塞性肺病)患者撤机失败和需要应用撤机技术的比例显著高于外科和其他原因导致的急性呼衰患者,外科术后及其它原因致急性呼吸衰竭患者的血气分析值与拔管时机及呼吸机应用时间长短无明显相关性(P>0.05),而COPD患者撤机后PaCO2潴留与其机械通气时间延长密切相关(P<0.05)。结论目前应用的客观撤机指标对撤机指导意义有限,临床实践中应同时考虑患者全身情况、心理状态及疾病变化等,这对COPD患者尤其重要。
Objective To investigate the related factor of weaning in patien ts with mechanical ventilation and the feasibility of weaning index, in order to g uide clinic. Methods To retrospective analyse on 96 cases with mechanical ventil ation . The related factores were collected about weaning, and were statistical analysed. Results Proportion of acute respiratoty failure patients of failing we aning in patients with mechanical ventilation and needed technic of weaning were significantly higher in the COPD than in other reasons. There was no significan t correlation between values of arterial blood gases analysis in acute respirato ty failure patients, that were after surgery and other reasons and opportunity f or pull out tube and times of mechanical ventilation (P>0.05). The data suggest that a relationship indeed exists between high carbon dioxide after weaning from patients with COPD and prolong their times of mechanical ventilation (P<0.05). Conclusions The study suggests that current plied objective weaning index were i nadequate as a weaning indicator, clinical fulfillment the inside should conside r whole body circumstance, psychological condition and trend of disease, especia lly to the COPD patients.
