Reversal of Acute Hypoxic Pulmonary Hypertension with Inhalation of Nitric Oxide.

The effect of inhalation of nitric oxide（NO）gas on acute hypoxic pulmonary hypertension was studied.Eighteen mongrel dogs were divided into two groups; hypoxic control group（FIO=11％， n=10）and NO inhalation gloup（FIO=11％，NO inspiratory concentration=44ppm，n=8）.

Hemodynamic Effects of Inhaled Nitric Oxide in Patients with Pulmonary Hypertension.

Twelve patients with pulmonary hypertension (primary pulmonary hypertension in 3 cases, secondary to recurrent pulmonary embolism in 4 cases, chronic obstructive pulmonary disease in 2 cases and complicated with congeni-

亚硝酸乙酯和一氧化氮吸入治疗大鼠急性肺动脉高压的作用比较

新生儿持续性肺动脉高压(PPHN)是新生儿常见的危重症之一,病死率较高.自上世纪90年代临床使用一氧化氮(NO)吸入治疗肺动脉高压以来,发现其可选择性的舒张肺血管,临床效果显著,减少了体外膜肺(ECMO)的使用率[1].但NO易与氧或超氧离子形成毒性的氮氧化物,引起肺损伤、高铁血红蛋白血症等副作用,已受到人们的重视[2].传统的NO供体类药物如硝酸甘油、硝普钠等缺乏较好的肺血管选择性,而且长期使用容易产生耐药性[3].
