The satisfaction was high for the pediatrician (92.5%), the nurse (94.3%), the family (96.8%), and patients (93.6%), with a good correlation between them, and it was significantly lower when using midazolam and the nasal and oral routes. The adverse effects rate was 3.2%, and none was severe. CONCLUSIONS The implementation of a specific analgosedation protocol for procedures in the hospital environment achieves high levels of effectiveness and safety, as well as a high level of satisfaction, both in family members and in health personnel.INTRODUCTION There are few conclusive studies on the usefulness of High-Flow Nasal Cannula (HFNC) Oxygen Therapy in patients with asthmatic crises. OBJECTIVE To determine the effectiveness of HFNC in chil dren older than 2 years of age that present severe and moderate asthmatic crises that do not respond to initial treatment. PATIENTS AND METHOD Open controlled randomized clinical trial of patients with asthma exacerbation in the Pediatric Emergency Department. Infection- and comorbidity-media ted crises were excluded. Subjects were randomized as follows Group 1 HFNC (n32) and Group 2 Conventional Oxygen Therapy (n33). Both groups received the usual pharmacological treatment. The first cut-off point was the decrease of more than 2 points of the PIS after 2 hours of treatment; secondary points were PIS decrease at 6 hours, stay time in the Emergency Room, and PICU admis sion. RESULTS The patient's baseline characteristics were similar in both groups. The proportion of subjects with more than two points decrease in the PIS after two hours of treatment in Group 1 was 43.7% CI 95% (28-60) vs. Group 2 48.4%; CI 95% (32-64) p 0.447. The mean stay time was 24.8 ± 12.3 hours in Group 1 vs. 24 ± 14.8 hours in Group 2; CI 95% (7.56-5.96) p 0.37. We did
