Multicenter randomized clinical trial comparing dexamethasone versus placebo in preventing upper airway obstruction after extubation in critically ill children.

To analyze the effectiveness of dexamethasone in preventing upper airway obstruction (UAO) symptoms after extubation and the need of reintubation in critically ill children. Multicenter, prospective, double-blind, randomized, phase IV clinical trial involving five pediatric intensive care units. Children between 1 month and 16 years-of-age intubated for more than 48 h were included. Patients were randomized to receive placebo or dexamethasone 0.25 mg/kg every 6 h, 6-to-12 h prior to extubation (four doses). 48 h follow-up was carried out after extubation. Severity of UAO symptoms (Taussig score, stridor) and reintubation requirement were compared. 147 patients were randomized (10 were excluded), 70 patients received dexamethasone and 67 placebo. No global differences were found in the presence of stridor or moderate-to-severe UAO symptoms (Taussig ≥ 5), but Taussig ≥ 5 was less frequent in patients less than 2 years-of-age treated with steroids (p = 0.014). Median Taussig score was lower in the dexamethasone group 1 h after extubation, p < 0.001. 27 patients required reintubation, 9 due to UAO: 3 (4.3%) in the dexamethasone group and 6 (8.9%) in the placebo group, p = 0.319. In those intubated > 5 days, reintubation due to UAO was higher in the placebo group (2.4% vs. 14.3, p = 0.052). Nebulized epinephrine and budesonide were required more frequently in the placebo group in the first 2 h (p = 0.041) and 1 h (p = 0.02) after extubation, respectively. No relevant side effects were observed. Dexamethasone prior to extubation did not significantly reduce moderate-severe UAO symptoms, except for patients under 2-years of age. Dexamethasone could decrease Taussig score and the need of rescue therapies, as well as reintubation rates in those intubated for more than 5 days.

[Off-label and unlicensed drug use: Results from a pilot study in a pediatric intensive care unit]. / Utilización de medicamentos en condiciones off-label y unlicensed: resultados de un estudio piloto realizado en una unidad de cuidados intensivos pediátricos.

PURPOSE: To analyze the prevalence of use of off-label and unlicensed drugs in a pediatric intensive care unit of a University Hospital. METHOD: An observational, descriptive, prospective six week pilot study in a Pediatric Intensive Care Unit. Hospitalized patients aged between 0 and 18 years were included. Each prescribed drug was evaluated taking into account indication and condition of use, according to the information available on the Summary of Product Characteristics established by the European Medicines Agency. A sequential algorithm was defined allowing drug classification in unlicensed, off-label or approved. RESULTS: Forty-two patients were included. A total of 696 prescriptions, involving 102 different drugs, were analyzed. All patients had at least one off-label prescription, and a median of 8.9 off-label prescriptions was obtained. Of the total prescriptions, 8.6% were unlicensed and 53.9% corresponded to off-label use. The main reason for off-label use was by indication, followed by age and dose. A lineal tendency between off-label drug use and patient age was observed, where off-label use increased as patient age decreased. The drugs most commonly used off-label were: atropine, etomidate, dipyrone and ranitidine, and unlicensed drugs: spironolactone, sildenafil, acetazolamide and hydrochlorothiazide. CONCLUSION: Pediatric Intensive Care Units are characterized by a high ratio of off-label and unlicensed prescriptions. The scarce number of studies performed in this specific and complex sub-population added inconveniency to the current lack of data on safety and efficacy for drugs in paediatrics. Performing studies with these characteristics allows us to document practice on paediatric drug utilisation are required.
