Abstract |
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.
