Factors Associated with Lung Function Recovery at the First Year after Lung Transplantation

다국어 초록 (Multilingual Abstract)

Purpose: Post-operative pulmonary function is an important prognostic factor for lung transplantation. The purpose of this studywas to identify factors affecting recovery of forced expiratory volume in 1 second (FEV1) at the first year after lung transplantation.
Materials and Methods: We retrospectively reviewed the medical records of lung transplantation patients between October 2012and June 2016. Patients who survived for longer than one year and who underwent pulmonary function test at the first year of lungtransplantation were enrolled. Patients were divided into two groups according to whether they recovered to a normal range ofFEV1 (FEV1 ≥80% of predicted value vs. <80%). We compared the two groups and analyzed factors associated with lung functionrecovery.
Results: Fifty-eight patients were enrolled in this study: 28 patients (48%) recovered to a FEV1 ≥80% of the predicted value, whereas30 patients (52%) did not. Younger recipients [odds ratio (OR), 0.92; 95% confidence interval (CI), 0.87–0.98; p=0.010], longerduration of mechanical ventilator use after surgery (OR, 1.14; 95% CI, 1.03–1.26; p=0.015), and high-grade primary graft dysfunction(OR, 8.08; 95% CI, 1.67–39.18; p=0.009) were identified as independent risk factors associated with a lack of full recovery oflung function at 1 year after lung transplantation.
Conclusion: Immediate postoperative status may be associated with recovery of lung function after lung transplantation.
