Treatment of the asthma crisis in children
The treatment of the acute crisis can be staggered according to the intensity of the crisis. In cases of mild crisis, treatment should be performed under the control of the physician and family nurse, either at the office level or at the home level, provided that family members have sufficient training

Inhaled salbutamol treatment (outline).
Salbutamol inhaled (with spacer and mask in very small children and in infants): 2-4 inh. C / 20 min. During the 1st hour of the mild 4-8 inh crisis. C / 20 min. During the 1st hour in moderate and severe seizures
Salbutamol in nebulization: 0.01 mg./Kg. (Maximum 5 mg.) 0.5% nebulizer solution Oxygenation of 5 to 6 liters / min should be taken into account.

If a good response is obtained: - normal respiratory rate, non-dyspnea, PEF> 80%. It is recommended to continue with outpatient treatment: Salbutamol for 3 to 4 hours and restart the usual inter-crisis prophylactic treatment used by the patient. You must attend the doctor's office, 24 hours after the acute crisis, to follow their evolution.
If incomplete response is obtained: - normal or increased respiratory rate, moderate dyspnea, mild intercostal impression, PEF 50-80%. A new cycle is recommended with Salbutamol and the early administration of corticosteroids, oral prednisone, 1-2 mg. / Kg. / Day (max 40 mg.) Of 3-7 days. If the answer is incomplete or bad, you should assess your transfer to the hospital emergency department.
If a poor response is obtained: - increased respiratory rate (> 60 / min) Major dyspnea, intercostal and suprasternal tracings, nasal flutter, cyanosis, PEF <50%. If you are in the health area (family doctor's office, in the police force), your immediate transfer to a pediatric hospital emergency department should be assessed.
