The Use of Vasopressors During Deceased Donor Pancreas Procurement Decreases the Risk of Pancreas Transplant Graft Failure.

OBJECTIVES: The objective of this study was to identify the effect of various vasopressors on pancreas graft failure and patient survival.

METHODS: A retrospective analysis of the United Network for Organ Sharing database was performed between 2000 and 2019. Patient and graft survival rates were analyzed up to 5 years posttransplant.

RESULTS: The data included 17,348 pancreas transplant recipients: 12,857 simultaneous pancreas-kidney, 1440 pancreas transplant alone, and 3051 pancreas-after-kidney transplant recipients. Use of dopamine during deceased donor procurement increased graft failure by 18% (hazard ratio [HR], 1.18; P < 0.001). Absence of vasopressor caused graft failure to rise by 8% (HR, 1.08; P = 0.09). Dopamine increased the mortality rate by 37% (HR, 1.37; P < 0.001) and the absence of vasopressor increased the mortality rate by 14% (HR, 1.14; P = 0.02). Phenylephrine and norepinephrine reduced the mortality rate by 10% (HR, 0.90; P = 0.05) and 11% (HR, 0.89; P = 0.10), respectively.

CONCLUSIONS: The absence of vasopressor use or the use of dopamine is associated with a higher risk of both pancreas transplant graft failure and recipient mortality. The use of phenylephrine and norepinephrine reduces the risk of mortality. This information should guide deceased donor hemodynamic support management in anticipation of pancreas procurement for future transplantation.
