目的 :探讨负压引流器治疗肺炎旁胸腔积液的效果。方法 :对 3 2例合并胸腔积液的病人根据年龄、积液量的多少 ,维持引流器最大负压值的 1/2压力进行间断引流 ,引流 2小时 ,夹管 2小时 ,持续间断引流 48～ 72小时。如B超示仍有积液 ,或呈多房分隔状 ,则将尿激酶从导管处做胸腔内注射。结果 :3 2例中显效 13例 ( 4 1% ) ,余为有效 ,无脓胸形成。结论 :该方法损伤少 ,效果好 ,对积液引流彻底 ,费用也较低。 Objective: To investigate the effect of negative pressure drainage device on pleural effusion of pneumonia. Methods: Thirty-two patients with pleural effusion underwent intermittent drainage according to the age and amount of effusion, maintaining the pressure of 1/2 of the maximum negative pressure value of the drainage device, drainage for 2 hours, pinching for 2 hours and continuing the intermittent drainage 48 ~ 72 hours. Such as B-ultrasound is still fluid, or were separated by multiple rooms, then urokinase from the catheter at the intrathoracic injection. Results: In 32 cases, 13 cases (41%) were markedly effective, the rest were effective and no empyema was formed. Conclusion: The method is less damaging and has good effect. It has thorough drainage and low cost.
