Based on the child's weight, 10, 15, or 20 carefully supervised epinephrine or placebo inhalations were attempted. Before dosing, and at intervals from 5 to 180 minutes after dosing, we monitored plasma epinephrine concentrations, blood glucose, heart rate, blood pressure, and adverse effects.<\/jats:p>\n <\/jats:sec>\n \n Results.<\/jats:title>\n Eleven children (mean \u00b1 standard error of the mean: 9 \u00b1 1 years and 33 \u00b1 3 kg) in the epinephrine group were able to inhale 11 \u00b1 2 (range: 3\u201320) puffs, equivalent to 74% \u00b1 7% of the precalculated dose or 0.078 \u00b1 0.009 mg\/kg. They achieved a mean peak plasma epinephrine concentration of 1822 \u00b1 413 (range: 230-4518) pg\/mL at 32.7 \u00b1 6.2 minutes. Eight children (10 \u00b1 1 years of age and 33 \u00b1 5 kg) in the placebo group were able to inhale 12 \u00b1 2 (range: 8\u201320) puffs, 89% \u00b1 3% of the precalculated dose, and had a peak endogenous plasma epinephrine concentration of 1316 \u00b1 247 (range: 522-2687) pg\/mL at 44.4 \u00b1 16.7 minutes. In the children receiving epinephrine compared with those receiving placebo, mean plasma epinephrine concentrations were not significantly higher at any time, mean blood glucose concentrations were significantly higher from 10 to 30 minutes, mean heart rate was not significantly different at any time, and mean systolic and diastolic blood pressures were not significantly increased at most times. After the inhalations of epinephrine or placebo, the children complained of bad taste and many experienced cough or dizziness. After inhaling epinephrine, 1 child developed nausea, pallor, and muscle twitching.<\/jats:p>\n <\/jats:sec>\n \n Conclusions.<\/jats:title>\n Despite expert coaching, because of the number of epinephrine inhalations required and the bad taste of the inhalations, most children were unable to inhale sufficient epinephrine to increase their plasma epinephrine concentrations promptly and significantly. Therefore, we urge caution in recommending epinephrine inhalation as a substitute for epinephrine injection for out-of-hospital treatment of anaphylaxis symptoms in children.<\/jats:p>\n <\/jats:sec>","DOI":"10.1542\/peds.106.5.1040","type":"journal-article","created":{"date-parts":[[2004,8,13]],"date-time":"2004-08-13T23:50:41Z","timestamp":1092441041000},"page":"1040-1044","source":"Crossref","is-referenced-by-count":85,"title":["Can Epinephrine Inhalations Be Substituted for Epinephrine Injection in Children at Risk for Systemic Anaphylaxis?"],"prefix":"10.1542","volume":"106","author":[{"given":"F.
