An integrated program to expand donor utilization in pediatric heart transplantation: Case report of successful transplant with multiple donor risk factors. Pediatric transplantation Torpoco Rivera, D. M., Hollander, S. A., Almond, C., Profita, E., Dykes, J. C., Raissadati, A., Lee, J., Sacks, L. D., Kleiman, Z. I., Lee, E., Rosenthal, A., Rosenthal, D.

Abstract

Pediatric heart transplantation (HT) continues to be limited by the shortage of donor organs, distance constraints, and the number of potential donor offers that are declined due to the presence of multiple risk factors.We report a case of successful pediatric HT in which multiple risk factors were mitigated through a combination of innovative donor utilization improvement strategies.An 11-year-old, 25-kilogram child with cardiomyopathy and pulmonary hypertension, on chronic milrinone therapy and anticoagulated with apixaban, was transplanted with a heart from a Hepatitis C virus positive donor and an increased donor-to-recipient weight ratio. Due to extended geographic distance, an extracorporeal heart preservation system (TransMedics OCS Heart) was used for procurement. No significant bleeding was observed post-operatively, and she was discharged by post-operative day 15 with normal biventricular systolic function. Post-transplant Hepatitis C virus seroconversion was successfully treated.Heart transplantation in donors with multiple risk factor can be achieved with an integrative team approach and should be taken into consideration when evaluating marginal donors in order to expand the current limited donor pool in pediatric patients.

Intraoperative Methadone Is Associated with Decreased Perioperative Opioid Use Without Adverse Events: A Case-Matched Cohort Study. Journal of cardiothoracic and vascular anesthesia Robinson, J. D., Caruso, T. J., Wu, M. n., Kleiman, Z. I., Kwiatkowski, D. M. 2019

Abstract

To determine if there is an association of intraoperative methadone use and total perioperative opioid exposure in patients undergoing congenital heart surgeries.Retrospective, case-match cohort study.Single center quaternary care teaching hospital.Seventy-four patients with congenital heart disease (CHD) undergoing surgical repair or palliative surgery.Thirty-seven patients undergoing CHD surgeries receiving intraoperative methadone were matched to 37 patients based upon age and procedure who did not receive intraoperative methadone. The primary study outcome was to evaluate total opioid use in intravenous milligrams of morphine equivalents per kilogram (mg ME/kg) within the first 36-hours postoperatively. Mann-Whitney U test was used to compare total opioid exposure.The total opioid use was compared between groups. The methadone cohort required less opioids intraoperatively, in the first 12 hours postoperatively, and during the first 36 hours postoperatively (2.51 v 4.39 mg ME/kg, p < 0.001; 0.43 v 1.28 mg ME/kg, p=0.001; and 0.83 v 1.91 mg ME/kg, p < 0.001) compared with the matched control cohort. There were no differences in clinical outcomes or adverse events. A dose-dependent reduction in opioid consumption in high- versus low-dose groups also was not observed.Intraoperative methadone use was associated with a decrease in perioperative opioid exposure in patients undergoing congenital heart surgery and was not associated with adverse events or prolonged durations of mechanical ventilation or ICU stay.
