摘要目的：探讨专职护理小组对COPD伴呼吸衰竭序贯通气患者的影响。方法选择在我院ICU实施序贯通气COPD的患者，采用回顾性研究。将2011年1月至2011年11月实施序贯通气的COPD患者作为观察组（实施后），由专职护理小组实施系统性护理干预。将2010年1月至2010年11月实施序贯通气的COPD患者作为对照组（实施前），实施常规的护理。观察临床应用的效果。结果经统计学处理，观察组护士对序贯通气知识掌握程度明显高于对照组，有显著性差异（ P＜0.01）；观察组在再插管率、VAP发生率、有创通气时间、总通气时间、住ICU时间等方面明显低于对照组，有显著性差异（P＜0.05，P＜0.01）。结论专职护理小组可有效提高COPD伴呼吸衰竭进行序贯机械通气治疗的顺利实施和疗效，避免患者因撤机失败和再次插管上机所带来的痛苦及经济负担，提高患者的生活质量，促进患者早日康复，提高整体护理水平，值得临床推广应用。

abstractsObjective To investigate the impact of critical cases specialized nursing group on the sequential ventilation of COPD patients with respiratory failure.Methods The COPD patients with respiratory failure who were implemented with sequential ventilation in our hospital ICU were selected for research with the retrospective study.The patients from January to November of 2011 who were nursed by the critical cases specialized nursing group were divided into the observation group , the other patients from January to November of 2010 who were nursed by the routine care were divided into the control group , and the clinic effect was observed .Results The nurses of the observa-tion group knew much better about the knowledge of sequential ventilation than them of the control group , the differences were statistically significant ( P<0.01 ) .Re-intubation rate , VAP incidence , duration of the invasive ventilation , total duration of ventilation , and the du-ration in ICU of the patients in the observation group were significantly lower than those of the control group ( P<0.05 , P<0.01 ) .Con-clusions The critical cases specialized nursing group could effectively improve implementation and efficacy of the treatment of the COPD pa -tients with respiratory failure treated by the sequential ventilation , avoid the distress and financial burden because of the failure of weaning and re-intubation , improve the life quality , promote the recovery of the patients , elevate the overall standard of care.It is worthy of clinical application.
