Purpose:
There are limited data regarding hospital and intensive care unit (ICU) outcomes in patients with hepatopulmonary syndrome (HPS) following liver transplantation (LT).
Methods:
Data were retrospectively collected from consecutive HPS adult patients who underwent LT and were immediately admitted to the ICU at three transplant centers with shared management protocols, from 2002 to 2018. Demographic, clinical, surgical, laboratory, and outcome data were extracted.
Results:
We identified 137 patients (74 male, 54%), with a median age at LT of 58 years (IQR: 52-63). One hundred and 31 (95.6%) patients were admitted to the ICU on invasive mechanical ventilation (MV). The median time on invasive MV in the ICU was 12 hours (IQR: 5-28) and 97 patients (74%) were extubated within 24 hours of ICU admission. The median highest positive end expiratory pressure and fraction of inspired oxygen (FiO2) were 7 (IQR: 5-8) and 0.6 (IQR: 0.5-0.7), respectively. 7 patients (5%) developed severe post-transplant hypoxemia. Of all patients, 42 (30.4%) required vasopressors and the median ICU and hospital length of stay (LOS) were 3 (IQR: 1-5) and 10 (IQR: 7-20) days, respectively. The in-hospital mortality rate was 3.6% (5/137). HPS severity was not associated with hospital mortality.
Conclusion:
Most HPS patients have short durations of MV, ICU, and hospital LOS post-LT. HPS severity does not impact hospital mortality.
