Abstract
To investigate the high-risk factors for early pulmonary bacterial infection following lung transplantation and their association with long-term mortality. A retrospective analysis was conducted on 142 lung transplant recipients treated at Wuxi People's Hospital between January 2018 and July 2022. After applying predefined inclusion and exclusion criteria, 111 cases were analyzed. Univariate and multivariate logistic regression analyses were performed to identify independent risk factors for early pulmonary infection post-transplantation. Additionally, univariate and multivariate Cox regression analyses were used to identify independent prognostic factors affecting one-year survival post-transplantation. Univariate analysis identified age, bacterial infection in donor lungs, and operation duration as risk factors for early pulmonary infection (all P < 0.05). Multivariate analysis was confirmatory for these as independent risk factors (all P < 0.05). Univariate analysis also showed that intraoperative blood loss and oxygenation index impacted one-year survival (P < 0.05). Multivariate analysis was confirmatory for these as independent risk factors (P < 0.05). Early pulmonary bacterial infection was not found to be an independent factor affecting 1-year survival. However, substantial intraoperative blood loss and a reduced oxygenation index were identified as independent risk factors associated with increased mortality within 1 year post-transplantation.
