Interest of low-dose hydrocortisone therapy during brain-dead organ donor resuscitation: the CORTICOME study.
Résumé
INTRODUCTION: Circulatory failure during brain death organ donor resuscitation is a problem that compromises recovery of organs. Combined administration of steroid, thyroxine and vasopressin has been proposed to optimize the management of brain deceased donors before recovery of organs. However the single administration of hydrocortisone has not been rigorously evaluated in any trial. METHODS: In this prospective multicenter cluster study, 259 subjects were included. Administration of low-dose steroids composed the steroid group (n = 102). RESULTS: Although there were more patients in the steroid group who received norepinephrine before brain death (80% vs. 66%: P = 0.03), mean dose of vasopressor administered after brain death was significantly lower than in the control group (1.18 ± 0.92 mg/H vs. 1.49 ± 1.29 mg/H: P = 0.03), duration of vasopressor support use was shorter (874 min vs. 1160 min: P < 0.0001) and norepinephrine weaning before aortic clamping was more frequent (33.8% vs. 9.5%: P < 0.0001). Using a survival approach, probability of norepinephrine weaning was significantly different between the two groups (P < 0.0001) with a probability of weaning 4.67 times higher in the steroid group than in the control group (95% CI: 2.30 - 9.49). CONCLUSIONS: Despite no observed benefits of the steroid administration on primary function recovery of transplanted grafts, administration of glucocorticoids should be a part of the resuscitation management of deceased donors with hemodynamic instability.
