BACKGROUND: Postoperative fluid management is important after open heart surgery, because cardiopulmonary bypass evokes an abnormal inflammatory response and increases vascular permeability, especially in pediatric patients. We assessed the safety and effectiveness of tolvaptan for management of postoperative fluid retention after congenital heart surgery.
METHODS AND RESULTS: This retrospective study analyzed data from 43 children with uncomplicated congenital heart disease who underwent open heart surgery between September 2013 and August 2016. The patients were divided into two groups. Group N (n = 18; September 2013 through May 2014) received the conventional oral diuretics alone, and Group T (n = 25; June 2014 through August 2016) received a single dose of tolvaptan (0.45 mg/kg) in addition to the conventional oral diuretic therapy. Data were collected, while patients who received intensive care were assessed and compared between groups. Add-on tolvaptan use was associated with increased urinary output standardized by body weight (54.3 ± 4.5 vs 47.3 ± 19.1 mL/kg; p = 0.043), decreased additional intravenous diuretic dose standardized by body weight (0.26 ± 0.23 vs 0.62 ± 0.48 mg/kg; p = 0.001), and a smaller decrease in central venous pressure (1.3 ± 2.7 vs 1.9 ± 3.8 mmHg; p = 0.019). Laboratory analysis showed that electrolyte concentrations in blood and urine did not significantly differ between groups.
CONCLUSIONS: Tolvaptan appears to be effective and safe for management of postoperative fluid retention after congenital heart surgery.
