The effect of low doses of fenoterol in the treatment of moderate asthma crisis in children was evaluated through a quasi-experimental study in the Emergency Service of the Hospital Belén de Trujillo (HBT), September 2015 - August 2017. A population of 90 children between 4 and 14 years 11 months of age, of both sexes, with moderate asthmatic crisis; were randomly distributed into 3 groups, their initial lung function was measured by Peak Expiratory Flow (PEF), and groups I, II and III were nebulized every 20 minutes for one hour with fenoterol at conventional doses, 75% and 50% of doses respectively; lung function (PEF) and cardiac function (rhythm and rate) were assessed 10 minutes after each nebulization. The results were validated using the student's t test, with p<0.05 and the X2 test for group comparison with P <0.05. Ethical considerations were met for this type of study. The results found of variation of the PEF were comparable between Groups I, II and III (p> 0.05). But lower doses of fenoterol (group III) conditions significantly less heart rhythm alteration than Groups I and II (P <0.005). It was concluded that at low doses fenoterol promotes the recovery of lung function with slight alteration of cardiac function in children with moderate asthmatic crisis
