Prolonged mechanical ventilation (PMV), a common clinical manifestation, may result in fatal outcomes after living donor liver transplantation (LDLT). Although hyponatremia contributes to neurologic alterations in association with PMV, the effects of acute changes in hyponatremia during LDLT have not been well studied. We sought to determine whether an acute change in hyponatremia during surgery might be a risk factor for PMV after LDLT. ⋯ A multivariate analysis revealed that preoperative hepatic encephalopathy, hypotension during surgery (more than 3 bowls), and intraoperative changes in hyponatremia were predictive of PMV. Among the hyponatremia change subgroups, only a severe intraoperative change (≥10 mEq/L) was associated with PMV occurrence (odds ratio, 5.85; 95% confidence interval, 1.62 to 21.20, P = .007). In conclusion, a severe intraoperative change in hyponatremia was a risk factor for PMV in the immediate period after LDLT.
