The authors investigated the effectiveness of the blood patch technique in reducing the pneumothorax and chest tube insertion rates after transthoracic needle lung biopsy. Biopsy of 100 pulmonary nodules was performed with a coaxial system. In this prospective, randomized study, patients either received a blood patch (group A, n = 46) or did not (group B, n = 47). Seven procedures were excluded: five for technical reasons and two because of lack of follow-up information. Comparison of the two groups by means of X2 analysis and the Student t test revealed no difference in the mean age, gender, smoking history, proportion of heavy smokers, nodule size, presence of cavitation, or number of needle passes. The pneumothorax rate was 24% (11 of 46 patients) in group A and 30% (14 of 47 patients) in group B. The chest tube insertion rate was 2.2% (one patient) in group A and 2.1% (one patient) in group B. The difference between the groups in either rate was not significant (P greater than .5). The blood patch technique did not lower the rate of pneumothorax or chest tube insertion.
作者研究了血补丁技术在降低经胸针吸肺活检后气胸和胸腔置管率方面的有效性。使用同轴系统对100个肺结节进行活检。在这项前瞻性随机研究中，患者要么接受血补丁治疗（A组，n = 46），要么不接受（B组，n = 47）。排除了7例手术：5例因技术原因，2例因缺乏随访信息。通过X2分析和Student t检验对两组进行比较，结果显示两组在平均年龄、性别、吸烟史、重度吸烟者比例、结节大小、空洞形成情况或穿刺次数方面无差异。A组气胸发生率为24%（46例患者中的11例），B组为30%（47例患者中的14例）。A组胸腔置管率为2.2%（1例患者），B组为2.1%（1例患者）。两组在任何一项发生率上的差异均无统计学意义（P大于0.5）。血补丁技术并未降低气胸或胸腔置管率。
