Inhaled nitric oxide (iNO) therapy is effective in treating PPHN in term infants;however, the efficacy of iNO in preterm infants has not been established. We investigated the efficacy and safety of iNO as a treatment for preterm infants born at <30 weeks' gestation. The subjects were 39 preterm infants born at <30 weeks' gestation who underwent iNO therapy within 3 days of birth. The subjects' pulmonary hypertension was most commonly caused by pneumonia and sepsis. PPHN improved in 64 % of the subjects 1 hour after starting iNO. In many subjects, iNO was successfully reduced and withdrawn promptly after PPHN improved. Subjects in whom iNO was ineffective were commonly those born early and with lower birth weight. Mild methemoglobinemia was complicated in 2 subjects. In preterm infants with PPHN, iNO is a useful therapythat causes few adverse events and improves hemodynamics soon after birth within a short amount of time., 原著}, pages = {71--75}, title = {早産児の遷延性肺高血圧症に対するNO吸入療法の有効性・安全性の検討}, volume = {42}, year = {2015}, yomi = {ワタベ, ヤエコ and ワタベ, ヨシユキ and カノウ, ユウジ and カリヤ, カツラ and イチカワ, ゴウ and クリバヤシ, リヨウタ and ツボイ, ヤヨイ and スズムラ, ヒロシ and アリサカ, オサム} }
