Donor-related Risk Factors Associated With Increased Mortality After Lung Transplant.

Abstract

BACKGROUND:

Lung transplant is a surgical procedure for end-stage lung disease. Many factors related to lung donors influence the outcome of transplant. The main aim of this single-center study was to assess which donor-related and procedure-related factors would influence the 30-day or hospital mortality of the recipients.

METHODS:

This retrospective study group consisted of 110 donor-recipient pairs undergoing lung transplant between 2012 and 2017 (group 1) and 2018 and 2019 (group 2) in Silesian Center for Heart Diseases. Both groups of donor- and procedure-related factors were included in the analysis: oxygenation index at reporting of the donor, time donor spent in the intensive care unit (ICU), presence of cardiac arrest while being in the ICU, donor age, type of transplant, cumulative ischemia time, duration of the operation, and time of mechanical ventilation.

RESULTS:

The type of surgery was significantly associated with an increase in the chance of death within 30 days. Patients who underwent single lung transplant had a 20.217 times greater chance of dying within 30 days than patients after double lung transplant (interquartile range, 2.116-193.125).

CONCLUSIONS:

Single lung transplant increases the risk of death during the first 30 days after lung transplant, and using lungs from older donors may increase the rate of hospital mortality. Oxygenation index, sudden cardiac arrest of the donors, and donor time spent in the ICU do not impact the short-term mortality of lung graft recipients.
