ObjectiveLung transplantation is a complex surgical procedure performed by specialized teams. Practice changes to eliminate overnight lung transplants were implemented at our center and patient outcomes were evaluated.MethodsPatient and donor organ selection were performed in the standard fashion. All donors with a cross clamp after 6 PM matched to any of our listed recipients-independent of their surgical complexity or risk-were kept in a temperature-controlled iceless cooler from procurement to recipient implant. All recipients had a 7 AM in-room start. Data were prospectively collected and compared to a cohort of recipients from the previous fifteen months.Results82 transplants were performed at a single academic institution between 7/1/22 and 1/7/24, 21% of which included allografts with extended ischemic times utilizing the iceless cooler (n=18) with a median average temperature of 6.81 degrees Celsius. Median ischemic times were 13.9 (12.5 - 15.6) hours, more than twice the length of ischemic times in the standard group (n=64, 6.8 (6.1 - 7.4) hours). Post-operative outcomes were similar between groups, including post-operative ICU duration (12 vs 9 days in the standard group), length of stay (24 vs 20 days), PGD3 (17% vs 20%), post-operative ECMO (22% vs 20%), and six-month survival (94% vs 91%).ConclusionsDonor lungs preserved in an iceless cooler were successfully transplanted after extended cold ischemic times. Adoption of a semi-elective transplant strategy can be successfully implemented without compromising patient outcomes. Additional advantages may be gleaned through daytime transplantation with standard transplant surgical teams rather than overnight, on call-teams.Copyright © 2024 The Authors.
