to investigate the factors associated with extubation failure of patients in the intensive care unit.
unpaired, longitudinal, retrospective and quantitative case-control with the participation of 480 patients through clinical parameters for ventilator weaning. Data were analyzed by: Fisher's exact test or the chi-square test; unpaired two-tailed Student's t test; and Mann-Whitney test. Significant P values lower than or equal to 0.05 were admitted.
of the patients, 415 (86.5%) were successful and 65 (13.5%) failed. Success group: the most negative fluid balance, APACHE II in 20 (14-25), weak cough in 58 (13.9%). Failure group: the most positive fluid balance, APACHE II in 23 (19-29), weak cough in 31 (47.7%), abundant amount of pulmonary secretions in 47.7%.
positive fluid balance and the presence of inefficient cough or inability to clear the airway were predictors of extubation failure.
探讨与 ICU 患者拔管失败相关的因素。
采用非配对、纵向、回顾性和定量病例对照研究，通过临床参数对 480 例患者进行呼吸机撤机。采用 Fisher 确切检验或卡方检验、未配对双尾 Student t 检验和 Mann-Whitney 检验进行数据分析。P 值小于或等于 0.05 为有统计学意义。
患者中 415 例（86.5%）成功，65 例（13.5%）失败。成功组：液体负平衡最多，APACHE II 为 20（14-25），咳嗽无力 58 例（13.9%）。失败组：液体正平衡最多，APACHE II 为 23（19-29），咳嗽无力 31 例（47.7%），肺部分泌物多 47.7%。
液体正平衡和低效咳嗽或不能清除气道的存在是拔管失败的预测因素。
