【摘要】 对4例先天性心脏病室间隔缺损伴肺动脉高压患儿用Swan－Ganz导管监测血流动力学的情况下，观察吸入10mg／LNO后肺动脉压力及心输出量等的改变，结果表明，先天性心脏病室间隔缺损合并肺动脉高压患儿吸入低浓度NO气后，平均肺动脉压及肺血管阻力均较基础状态明显降低（P＜0．05），心输出量则较前增高。提示吸入10mg／LNO可明显降低先天性心脏病伴肺动脉高压患儿的肺动脉压力，增加心输出量。更多还原

【Abstract】 The changes of pulmonary arterypressure and cardic output after inhalation of NitricOxide (NO) (10mg/L) in 4 patients with congenitalheart disease complicated by pulmonary hypertension were studied. The hemodynamic changes weremonitored via Swan-Ganz catheter. The resultsshowed that: in patients with congenital heart disease complicated by pulmonary hypertension, inbalation of NO caused decrease in pulmonary arterypressure (systolic, diastolic and mean ), pulmonaryvascular resistance (P < 0. 05) and increase incardic output (P <0. 05).更多还原
