RESUMO

OBJECTIVES: Lung transplantation is associated with a significant risk of needed transfusion. Although algorithm-based transfusion strategies that promote a high fresh frozen plasma:red blood cells (FFP:RBC) ratio have reduced overall blood product requirements in other populations, large-volume transfusions have been linked to primary graft dysfunction (PGD) in lung transplantation, particularly use of platelets and plasma. The authors hypothesized that in lung transplant recipients requiring large-volume transfusions, a higher FFP:RBC ratio would be associated with increased PGD severity at 72 hours. DESIGN: Observational retrospective review. SETTING: Single tertiary academic center. PARTICIPANTS: Adult patients undergoing bilateral or single orthotopic lung transplantation and receiving >4 U PRBC in the first 72 hours from February 2014 to March 2019. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Patient demographics, operative characteristics, blood transfusions, and outcomes including PGD scores and length of stay were collected. Eighty-nine patients received >4U PRBC, had available 72-hour PGD data, and were included in the study. These patients were grouped into a high-ratio (>1:2 units of FFP:RBC, N = 38) or low-ratio group (<1:2 units of FFP:RBC, N = 51). Patients in the high-ratio group received more transfusions and factor concentrates and had significantly longer case length. The high-ratio group had a higher rate of severe PGD at 72 hours (60.5% v 23.5%, p = 0.0013) and longer hospital length of stay (40 v 32 days, p = 0.0273). CONCLUSIONS: In bleeding lung transplantation patients at high risk for PGD, a high FFP:RBC transfusion ratio was associated with worsened 72-hour PGD scores when compared with the low-ratio cohort.

RESUMO

BACKGROUND: Differences in outcomes by indication for venoarterial extracorporeal life support (VA-ECLS) are poorly described. We hypothesized that patients on VA-ECLS for acute pulmonary embolism (PE) have fewer complications and better survival than patients on VA-ECLS for other indications. METHODS: All patients ≥18 years on VA-ECLS from the Extracorporeal Life Support Organization global registry (2010-2019) were evaluated (n = 29,842). After excluding patients aged >79 years (n = 729) and those with incomplete indication data (n = 2530), patients were stratified by VA-ECLS indication for PE vs all other indications. The association between being discharged alive and each type of complication with VA-ECLS indication was assessed. RESULTS: Of 26,583 patients included in the analysis, 978 (3.7%) were on VA-ECLS for a primary diagnosis of acute PE. Acute PE patients were younger (53.1 vs 56.7 years, P < .001) and were more likely to be women (52.1% vs 32.3%, P < .001). Patients who underwent VA-ECLS for acute PE were 78% more likely to be discharged alive vs patients supported with VA-ECLS for other reasons (52.8% vs 40.4%; P < .001). Acute PE patients had fewer cardiovascular and renal complications (26.6% vs 38.0% and 31.1% vs 39.4%, respectively; adjusted P < .001). Acute PE patients had higher odds of having clots and mechanical complications (8.7% vs 7.9% and 16.7% vs 14.6%, respectively; adjusted P < .001). CONCLUSIONS: Patients undergoing VA-ECLS for acute PE have higher odds of survival to hospital discharge compared with those supported for other indications. Additionally, VA-ECLS in this population is associated with fewer cardiovascular and renal complications but higher mechanical complications.
