There is controversy regarding the mean arterial pressure (MAP) goals that should be targeted in the treatment of hepatorenal syndrome (HRS.) We conducted a study to assess different MAP targets in HRS in the intensive care unit (ICU).
MATERIALS AND METHODS:
This is a prospective randomized controlled pilot trial. ICU patients had target mean arterial pressure (MAP)?≥?85?mmHg (control arm) or 65-70?mmHg (study arm). Urine output and serum creatinine were trended and recorded.
A total of 18 patients were enrolled. The day four urine output in the high and low MAP group was 1194 (SD?=?1249) mL/24?h and 920 (SD?=?812) mL/24?h, respectively. The difference in day four - day one urine output was -689 (SD?=?1684) mL/24?h and 272 (SD?=?582) mL/24?h for the high and low MAP groups. The difference in serum creatinine at day four - day one was -0.54 (SD?=?0.63) mg/dL and?-?0.77 (SD?=?1.14) mg/dL in the high and low MAP groups, respectively.
In this study, we failed to prove non-inferiority between a low and high target MAP in patients with HRS.
This trial was registered with and approved by the University of Louisville Internal Review Board and hospital research review committees (IRB # 14.1190). The trial was registered with ClinicalTrials.gov (ID # NCT02789150).
