为评价吸入一氧化氮（ＮＯ）对犬吸入性损伤毒副作用的影响和预防。将１７只犬随机分为对照和治疗组，均经烟雾吸入致伤后，对照组单纯吸Ｏ２；治疗组吸Ｏ２和ＮＯ混合气体。间断监测吸入混合气体中二氧化氨（ＮＯ２）浓度和动脉血变化。结果表明，ＮＯ２经钠石灰处理后比处理前降低８０．２％，治疗组动脉血高铁血红蛋白（ＭＨｂ）比对照组明显升高，在８和１２小时差异显著；动脉血浆亚硝酸盐（ＮＯ－２）和ＭＨｂ含量升高呈正相关。提示吸入ＮＯ疗法在混合气体中确实产生较高浓度ＮＯ２，动脉血ＭＨｂ浓度随吸入时间延长而逐渐升高
To evaluate the inhalation of nitric oxide (NO) effects and prevention of inhalation injury side effects of dogs. Seventeen dogs were randomly divided into control group and treatment group, both of which were injured by smoke inhalation. In the control group, only O2 was inhaled. In the treatment group, O2 and NO were mixed. Intermittent monitoring of inhaled gas mixture of ammonia (NO2) concentration and arterial blood changes. The results showed that NO2 decreased 80.2% after treated with soda lime, and the level of MHb in the treatment group was significantly higher than that in the control group at 8 and 12 hours. NO2- 2) and MHb content was positively correlated. Suggesting that inhaled NO therapy did produce higher concentrations of NO2 in the mixed gas and arterial MHb concentrations gradually increased with prolonged inhalation
