One hundred asthmatic children were examined for pulsus paradoxus, a palpable diminution or obliteration of the peripheral pulse during inspiration, while in bronchospasm. Pulsus was measured with a sphygmomanometer and the difference in systolic pressure between inspiration and expiration was noted. Seventy-five children with mild asthma had no palpable pulsus and responded with complete subsidence of symptoms with one or two injections of aqueous epinephrine, 1-1000. Twenty-five children had palpable pulsus ranging from 10 mm to 30 mm. Five patients with pulsus between 10 and 15 mm were admitted to the hospital with status asthmaticus and pneumonia; eight other patients responded to parenteral epinephrine. Twelve children had pulsus of 20 mm or greater and all were hospitalized for uncomplicated status asthmaticus. Pulsus paradoxus may be found in acute exacerbation of childhood asthma and its degree correlates with both the severity and response to bronchodilating agents.
对100名哮喘患儿进行了奇脉检查，奇脉是指在支气管痉挛时吸气期间外周脉搏明显减弱或消失。用血压计测量脉搏，并记录吸气和呼气时收缩压的差值。75名轻度哮喘患儿未触及奇脉，注射一两次1:1000的肾上腺素水溶液后症状完全缓解。25名患儿可触及奇脉，奇脉范围为10毫米至30毫米。5名奇脉在10至15毫米之间的患儿因哮喘持续状态和肺炎入院；其他8名患儿对注射肾上腺素有效。12名患儿奇脉在20毫米或以上，均因单纯性哮喘持续状态住院。儿童哮喘急性发作时可出现奇脉，其程度与病情严重程度及对支气管扩张剂的反应均相关。
