胸腔插管引流并向胸腔内滴入四环素(TCN)是治疗复发有症状恶性胸膜渗出的有效方法。TCN滴入后,旋转病人体位,以促进硬化剂与胸膜表面的接触,使TCN 分布到到整个胸膜腔。然而旋转体位,既费时间又给病人带来不适。为了了解TCN 在胸膜腔内的分布,作者研究了旋转体位与胸膜腔内TCN 分布的关系。5例有症状的恶性胸膜渗出病人,当胸水少于150ml 或消失时,以放射标记的TCN 进行胸膜固定闪烁扫描影象检查,未转体位前和转动后30及120分
Thoracic intubation and the introduction of tetracycline into the thoracic cavity (TCN) is an effective method for the treatment of recurrent symptomatic malignant pleural exudation. After TCN infusion, the patient’s position is rotated to promote contact of the hardener with the pleural surface, allowing the TCN to be distributed throughout the pleural space. However, rotating the position, both time-consuming and bring discomfort to the patient. To understand the distribution of TCN in the pleural space, we examined the relationship between rotational position and TCN distribution in the pleural space. In 5 patients with symptomatic malignant pleural exudation, pleural scintigraphy was performed with radiofrequency-labeled TCN when the pleural effusion was less than 150 ml or disappeared, with 30 and 120 minutes before and after rotation
