Objectives:
The safety of living liver donors is considered a high priority. In this study, we aimed to highlight the incidence and risk factors of respiratory complications among living liver transplant donors at our institute.
Materials And Methods:
We evaluated data of 178 related living liver donors who were seen from January 2014 to December 2018. We recorded significant respiratory complications, such as pulmonary embolism, pleural effusion, pneumothorax, pneumonia, acute lung injury, acute respiratory distress syndrome, and transfusion-related acute lung injury. Complications were noted as clinically evident and/or needing intervention. We also recorded the frequency of nonrespiratory complications and duration of intensive care unit and hospital stays.
Results:
Ten donors (5.6%) developed significant respiratory complications: 2 (1.1%) had pulmonary embolisms, 3 (1.7%) developed symptomatic pleural effusion that required thoracentesis, and 4 (2.25%) had chest infections. The remaining donor (0.6%) had unexplained respiratory insufficiency. Logistic regression analyses identified age ≥ 35 years and previous surgery as the main risk factors of significant respiratory complications. There were no recorded cases of pneumothorax, acute lung injury, acute respiratory distress syndrome, and transfusion-related acute lung injury. Raw surface collection (14.6%) and biliary leakage (7.9%) were the most frequent nonrespiratory complications. There was no significant difference between patients with and without significant respiratory complications with regard to intensive care unit and hospital stays.
Conclusions:
Despite the low incidence of significant respiratory complications among our living liver donor cohort, close monitoring and early management are essential to achieve better prognosis, especially in donors older than 35 years or those with previous surgery.
