Objective  To analyze the curative effect of nitric oxide (NO) and bosentan on treatment of the interruption of aortic arch (IAA) with ventricular septal defect (VSD) and serious pulmonary hypertension (SPH). Methods  Thirty-two children with IAA and VSD combined SPH from January 2015 to May 2017 confirmed by cardiac CT and ultrasound in Children’s Hospital of Hebei Province were enrolled including 17 males and 15 females, aged 1.10-4.30 months (mean, 2.71±0.98 months) and weighing 3.33-6.10 kg (mean, 4.57±0.88 kg). The 32 children were randomly divided into two groups (n=16 in each), a NO group and a bosentan group. All the patients underwent interruption of aortic arch and ventricular septal defect repair. When patients returned to cardiosurgery intensive care unit (CSICU) half an hour later, patients in the NO group inhaled NO 20 ppm for 36 h and those in the bosentan group were given bosentan by nasogastric feeding 15 mg, twice a day. The cardic index, pulmonary/systemic pressure ratio, oxygenation index at 3 h, 6 h, 12 h, 24 h, 36 h after surgery were evaluated, and the differences between the two groups were compared. Results  The pulmonary/systemic pressure ratio in the two groups increased at first and then decreased, while oxygenation index in the two groups decreased at first and then increased, and the differences in the same groups at the adjacent time points were statistically significant (P<0.05). The cardiac index in the two groups decreased at first and then increased, the differences in the same groups at the adjacent time points were statistically significant, except for 6 h and 12 h after surgery in the bosentan group (P>0.05). At postoperative 6 h, 12 h, the oxygenation index in the NO group was significantly higher than that in the bosentan group, and the pulmonary/systemic pressure ratio in the NO group was less than that in the bosentan group (P<0.01). The cardiac index in the NO group was higher than that of the bosentan group after 6 h, 12 h, 24 h of operation, which were statistically significant (P<0.05), and the cardic index of children in the NO group was greatly higher than that in the bosentan group after 12 h of surgery (P<0.01); at the same time point, the corresponding indexes were not statistically significant between the two groups (P>0.05). Conclusion  NO inhalation in the treatment of IAA with VSD and SPH in children with early postoperative SPH is better than the bosentan, but in the late postoperative period, the effect is similar.
