The acute effects of thoracentesis on arterial oxygenation were observed in 19 studies on 17 patients. Arterial blood samples were obtained prior to, immediately after, and 1 h after thoracentesis. Unpredictable changes in the arterial oxygen tension, ranging from -22 to +19 mm Hg were found immediately following thoracentesis. It was concluded that significant hypoxemia may result from thoracentesis due to aberration of ventilation-perfusion relationships. It is further suggested that oxygen therapy be routinely administered during and immediately after the procedure.
在对17名患者进行的19项研究中观察了胸腔穿刺术对动脉氧合的急性影响。在胸腔穿刺术前、术后即刻及术后1小时采集动脉血样本。胸腔穿刺术后即刻发现动脉血氧张力出现不可预测的变化，范围为-22至+19毫米汞柱。得出的结论是，由于通气-灌注关系异常，胸腔穿刺术可能导致严重低氧血症。进一步建议在手术期间及术后即刻常规给予氧疗。
