Abstract

BACKGROUND

The role of intrapleural fibrinolytic agents in the treatment of childhood empyema has not been established. A randomised double blind placebo controlled trial of intrapleural urokinase was performed in children with parapneumonic empyema.

METHODS

Sixty children (median age 3.3 years) were recruited from 10 centres and randomised to receive either intrapleural urokinase 40 000 units in 40 ml or saline 12 hourly for 3 days. The primary outcome measure was length of hospital stay after entry to the trial.

RESULTS

Treatment with urokinase resulted in a significantly shorter hospital stay (7.4 v 9.5 days; ratio of geometric means 1.28, CI 1.16 to 1.41 p=0.027). A post hoc analysis showed that the use of small percutaneous drains was also associated with shorter hospital stay. Children treated with a combination of urokinase and a small drain had the shortest stay (6.0 days, CI 4.6 to 7.8).

CONCLUSION

Intrapleural urokinase is effective in treating empyema in children and significantly shortens hospital stay.

摘要

背景

胸膜内纤维蛋白溶解剂在儿童脓胸治疗中的作用尚未明确。对肺炎旁胸腔积液患儿进行了一项胸膜内使用尿激酶的随机双盲安慰剂对照试验。

方法

从10个中心招募了60名儿童(中位年龄3.3岁),随机分为两组,分别每12小时接受40ml含40000单位尿激酶的胸腔内注射或生理盐水注射,共3天。主要结局指标是进入试验后的住院时间。

结果

尿激酶治疗使住院时间显著缩短(7.4天对9.5天;几何均数比为1.28,可信区间为1.16至1.41,p = 0.027)。事后分析表明,使用小型经皮引流管也与较短的住院时间相关。接受尿激酶和小型引流管联合治疗的儿童住院时间最短(6.0天,可信区间为4.6至7.8)。

结论

胸膜内尿激酶对治疗儿童脓胸有效,并显著缩短住院时间。
