Abstract

Background: This retrospective study aims to identify clinical predictors of intraoperative blood loss during lung transplantation. While for other surgical specialties predictors of blood loss have been identified such as previous likewise located surgery, poor preoperative health status of patients, blood coagulation status, and use of extra corporeal circulation, predictors of blood loss during lung transplantation are not yet established.

Methods: A total of 326 lung transplants were performed between January 2000 and February 2014 at a tertiary hospital. The primary aim was to associate blood loss with the following potential predictors: pulmonary arterial hypertension, pre- or intraoperative extracorporeal life support (ECLS), previous thoracic surgery, previous lung transplant, and Charlson Comorbidity Index (CCI). Postoperative complications and 30-day mortality were secondary endpoints of the study.

Results: Median estimated blood loss during lung transplant was 1,500 mL (IQR, 1,000-2,875 mL). Pre- and intraoperative ECLS (P=0.02, P<0.001) independently increased blood loss by 59% and 107%, respectively. The higher blood loss during re-transplant marginally missed the significance level (P=0.05). Pulmonary arterial hypertension, previous thoracic surgery and high CCI were not associated with increased blood loss. As secondary outcomes, postoperative complications were more common in patients with a higher blood loss (P=0.04) but was not associated with higher 30-day mortality (P=0.18).

Conclusions: Pre- and intraoperative ECLS were significant risk factors for higher blood loss during lung transplantation. Higher blood loss was associated with higher incidence of postoperative complications but not with a higher 30-day mortality.
