BACKGROUND: Asthma is a chronic disease that requires an early diagnosis to avoid the phase of remodelation. OBJECTIVE: To evaluate transcutaneus tension of oxygen in challenge test with distilled water in pediatric patients with asthma. MATERIAL AND METHODS: Thirty patients of 1-5 years old were included: 15 with asthma and 15 control healthy subjects. Inclusion criteria were: clinical diagnosis of asthma (cough, respiratory difficulty and wheezes more than three times in the previous year), without using steroids four weeks before the study, or bronchodilators. Exclusion criteria were: respiratory infection and severe disease. A challenge test with cold distilled water was applied and O2 saturation and basal and 5, 10, 15, 20 and 30 minutes heart frequency were measured. RESULTS: O2 saturation statistically significant decreased from the basal to 5, 10, 15, 20 and 30 minutes; for cases: 96.4 and controls: 97.8, p = 0.00224. Heart frequency did not have a statistic change at basal, 5, 19, 15 and 20 minutes; but it had a statistically significant change at 30 minutes post-challenge (120.7 beats/min in cases vs 112.7 beats/min in controls, p = 0.0127). CONCLUSIONS: Pulse oxymetry has a significant value and is related to severity of illness.
