To determine if saline tract injection and rapid patient rollover following computed tomography (CT)-guided transthoracic needle biopsy (TTNB) affects pneumothorax incidence and size.
A retrospective cohort design was used to compare 278 patients who underwent post-biopsy saline injection and rapid rollover so that the biopsy site was dependent (N = 180) to a control group with routine post-biopsy care (N = 98). Post-procedure radiographs and CT were assessed for presence and size of pneumothorax, as well as requirement for chest tube placement.
Pneumothorax size as estimated on post-procedure CT was 3.33% in the treatment group and 6.63% in the control group (P < .05). There was also a reduction in chest tube placements in the treatment group (3.9% vs 10%, P < .05). On post-procedure radiographs, pneumothorax rates were 20% in the treatment group, and 25% in the control group (P > .05).
Saline injection with rapid patient rollover following TTNB significantly decreased pneumothorax size and chest tube placement but not incidence.
确定 CT 引导下经胸针吸活检（TTNB）后行盐水通道注射和快速患者翻身是否会影响气胸的发生率和大小。
采用回顾性队列设计，比较了行活检后盐水注射和快速翻身以使活检部位依赖（N=180）的 278 例患者与常规活检后护理的对照组（N=98）。术后进行 X 线和 CT 检查，以评估气胸的存在和大小，以及是否需要放置胸腔引流管。
治疗组术后 CT 估计的气胸大小为 3.33%，对照组为 6.63%（P<0.05）。治疗组胸腔引流管放置的数量也有所减少（3.9% vs 10%，P<0.05）。术后 X 线片上，治疗组气胸发生率为 20%，对照组为 25%（P>0.05）。
TTNB 后行盐水注射和快速患者翻身可显著减小气胸的大小和胸腔引流管的放置数量，但气胸的发生率无明显变化。
