The study set out to evaluate the relationship between the efficiency of pulmonary oxygenation and the extent of the reimplantation response as revealed on chest radiography after bilateral lung transplantation.
Postoperative chest radiographs of 31 patients who had undergone bilateral lung transplantation were evaluated for the extent of the reimplantation response. For each patient, the contemporaneous oxygenation indexes (partial pressure of oxygen in arterial blood divided by fraction of inspired oxygen) were calculated and correlated with a radiographic score produced from the evaluation of chest radiographs.
The method of evaluating chest radiographs for the extent of the reimplantation response was shown to be reproducible. Although mean oxygenation indexes were found to decrease with increasing radiographic scores, this trend was not statistically significant.
Although the extent of the reimplantation response on the early postoperative chest radiography inversely correlated with the oxygenation efficiency of the transplanted lungs, this finding was not statistically significant.
本研究旨在评估双侧肺移植术后胸部X线片显示的肺氧合效率与再植反应程度之间的关系。
对31例行双侧肺移植患者的术后胸部X线片进行再植反应程度评估。计算每位患者同期的氧合指数（动脉血氧分压除以吸入氧分数），并将其与胸部X线片评估得出的放射学评分进行关联分析。
评估胸部X线片再植反应程度的方法具有可重复性。尽管发现平均氧合指数随放射学评分增加而降低，但这种趋势无统计学意义。
虽然术后早期胸部X线片上的再植反应程度与移植肺的氧合效率呈负相关，但这一发现无统计学意义。
