作者自1963年起用Abram针作胸膜活检,结核性胸膜炎的阳性率为70％,重复检查则为80％。癌性胸膜炎胸膜活检阳性率为55％,重复检查则为60％。作者认为此检查系有价值的诊断方法而文献上尚无有关其危险性的系统分析。为此,作者重点分析了胸膜活检的危险性,以便对胸膜活检有更全面的了解。共作胸膜活检800次,其中发生气胸者25例(3.1％);胸膜腔内出血者11例(1.3％);癌肿沿穿刺道接种者15例(1.9％)。3例发生咯血(患者并无胸水,穿刺入肺引起)。胸膜腔内出血11例中8例为中等量出血,其中1例系在活检后7天因使用抗凝血剂而引起出血。另1 Since 1963, the author has used an Abram needle for pleural biopsy, with a positive rate of 70% for tuberculous pleurisy and 80% for repeat exam. Pleuropneumonia pleural biopsy positive rate of 55%, repeated examination was 60%. The authors consider this test a valuable diagnostic method and there is no systematic analysis of the risks involved in the literature. To this end, the author focused on the analysis of the risk of pleural biopsy in order to have a more comprehensive understanding of pleural biopsy. A total of 800 pleural biopsy were performed, of which 25 cases (3.1%) occurred pneumothorax; 11 cases (1.3%) of pleural cavity hemorrhage; 15 cases (1.9%) of cancer inoculation along the puncture. Hemoptysis occurred in 3 patients (the patient had no pleural effusion and puncture into the lungs). Among the 11 cases of intrapleural hemorrhage, 8 were moderate-grade bleeding, of which 1 was bleeding 7 days after biopsy due to the use of anticoagulants. Another one
