Abstract

AIMS:

The aim of this study was to assess the haemodynamic effects of tri-iodothyronine (T3) and methylprednisolone in potential heart donors.

METHODS AND RESULTS:

In a prospective randomized double-blind trial, 80 potential cardiac donors were allocated to receive T3 (0.8 microg kg(-1) bolus; 0.113 microg kg(-1) h(-1) infusion) (n = 20), methylprednisolone (1000 mg bolus) (n = 19), both drugs (n = 20), or placebo (n = 21) following initial haemodynamic assessment. After hormone or placebo administration, cardiac output-guided optimization was initiated, using vasopressin as a pressor and weaning norepinephrine and inotropes. Treatment was administered for 5.9 +/- 1.3 h until retrieval or end-assessment. Cardiac index increased significantly (P < 0.001) but administration of T3 and methylprednisolone alone or in combination did not affect this change or the heart retrieval rate. Thirty-five per cent (14/40) of initially marginal or dysfunctional hearts were suitable for transplant at end-assessment. At end-assessment, 50% of donor hearts fulfilled criteria for transplant suitability.

CONCLUSION:

Cardiac output-directed donor optimization improves donor circulatory status and has potential to increase the retrieval rate of donor hearts. Tri-iodothyronine and methylprednisolone therapy do not appear to acutely affect cardiovascular function or yield.
