RESUMO
Objective To Explored the relative factors which caused the extubation failure in neurological intensive care unit (NICU).Methods It was a retrospective study.40 cases of patients who met the criteria,were brought into statistical analysis.They were admitted in NICU in Nan Fang Hospital from December 2008 to February 2011.The name,sex,age,diagnosis,respiratory parameters,24 hours discrepancy quantity,sputum,and Glasgow Coma Scale,Full Outline of UnResponsiveness Scale were recorded.SPSS 13.0 was used as statistic software.P ＜ 0.05 was considered statistically significant.Results Both in extubation successful and failure groups,GCS and Four were significantly different (all P ＜ 0.05).Howerer,there were no statistically significant in the other factors.There were significantly differences between GCS and Four in predicting extubation results (P =0.012).Logistic multiple regression showed that Four and GCS grade were predictive factor of extubation failure (P =0.041).Conclusions The result suggests that it is statistically significant to use GCS and Four as factors to predict extubation results.It can be widely used to help medical personnels monitoring the changes of patients'clinical conditions,judging prognosis,and making treatment plan in NICU.Wether other factors would effect the extubation results,more prospective,randomized controlled studies were needed.
