BACKGROUND: Hormone replacement therapy (HRT) use for donors with hemodynamic instability is common. The purpose of this study was to determine the effect of HRT in donors without significant cardiovascular dysfunction and examine outcomes according to vasopressor exposure. METHODS: All successfully procured donors admitted between January 1, 2006, and March 31, 2011, were included. HRT group I were donors without significant hemodynamic instability at the initiation of HRT. Comparison was made to all other donors receiving HRT (HRT group II). Vasopressor use was also examined and compared. High-yield procurement was the successful recovery of ≥ 4 organs. RESULTS: Forty-seven donors were studied. Most were male (36 [76.6%]) and trauma (41% [87.2%]) predominated. Twenty-two (46.8%) patients were in HRT group I. There were no differences in gender, admission diagnosis, or complications; however, HRT group I had a significantly greater number of organs recovered (4.73 ± 1.42 vs. 3.08 ± 1.19, p < 0.001). Differences in rates for the heart (68.2% vs. 24%, p = 0.002) and lung (40.9% vs. 8.0%, p = 0.008) were marked. HRT group I was more likely managed on a single agent (45.5% vs. 8.0%, p = 0.003). Norepinephrine was associated with a decreased rate of high-yield procurement (48.0% vs. 77.3%, p = 0.039), while vasopressin exposure was associated with an absolute increase (72.0% vs. 59.1%, p = 0.351). After adjusting for differences between groups (particularly age), HRT group I status was independently associated with high-yield procurement. CONCLUSION: A more liberal strategy of HRT seems to significantly increase procurement rates. Vasopressor selection favoring vasopressin as opposed to norepinephrine may also play a role. LEVEL OF EVIDENCE: Therapeutic study, level III.
