E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess the efficacy of a loading dose of intravenous salbutamol in children admitted to a PICU for severe acute wheeze or severe acute asthma. Efficacy is measured by the reduction in asthma score (Qureshi) at 1 hour after administration of the loading dose, compared to placebo. |
Het bepalen van de efficacy van een oplaaddosis intraveneus salbutamol bij kinderen opgenomen op een PICU wegens ernstige (virale) wheeze of status asthmaticus. Efficacy wordt gemeten middels de afname in astma score (Qureshi) 1 uur na toediening van de loading dose, vergeleken met placebo. |
|
E.2.2 | Secondary objectives of the trial |
To assess the following pharmacodynamics parameters of a loading dose of intravenous salbutamol in children admitted to a PICU for severe acute wheeze or severe acute asthma. -Maximum rate and duration of infusion of IV salbutamol -Total (cumulative) dose of IV salbutamol -Length of stay on PICU -Need for other medication (e.g. sodium bicarbonate, theophyllin, sevoflurane) -Need for non-invasive/invasive mechanical ventilation (+ duration) -Frequency of side effects (Tachycardia, Arrhythmia, Hypotension, Hypokalaemia, Hyperglycaemia, Lactic acidosis) -Distribution of ADBR2 receptor polymorphisms
|
Het bepalen van de volgende farmacodynamische parameters van een oplaaddosis intraveneus salbutamol bij kinderen opgenomen op een PICU wegens ernstige (virale) wheeze of status asthmaticus. -Maximale infusiesnelheid en totale duur van infusie IV salbutamol -Totale (cumulatieve) dosis IV salbutamol -Verblijfsduur op de PICU -Noodzaak tot gebruik andere medicatie (bijv. natriumbicarbonaat, theophylline, sevofluraan) -Noodzaak tot inzet van niet-invasieve/invasieve mechanische ventilatie (+ duur) -Frequentie van optreden van bijwerkingen (Tachycardie, arrhythmie, hypotensie, hypokaliëmie, hyperglycemie, lactaat acidose) -Distributie van ADBR2 receptor polymorphismen |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
-Between 2-18 years of age at moment of inclusion -Admitted to PICU for Severe Acute Asthma or Severe acute (viral) wheeze -Requiring administration of IV salbutamol
|
-Tussen 2 en 18 jaar oud op moment van inclusie -Opgenomen op PICU wegens status astmaticus of ernstige acute (virale) wheeze -Noodzaak tot toediening van IV salbutamol |
|
E.4 | Principal exclusion criteria |
-Patient is outside of specified age range -Patient has already received a -loading dose- of IV salbutamol in the general hospital -Lower airway infection with consolidation on a chest X ray -Patient has Down’s Syndrome -Patient has a congenital/acquired heart defect that interferes with normal asthma treatment -Patient has a primary/secondary immunodeficiency -Patient has a pre-existing chronic pulmonary condition, known to mimic asthma: Cystic fibrosis, Bronchopulmonary dysplasia, Bronchiolitis obliterans
|
-Patiënt valt buiten het gespecificeerde leeftijdsbereik -Patiënt heeft reeds een -oplaaddosis- IV salbutamol ontvangen in het algemene ziekenhuis -Lagere luchtweg infectie met consolidatie op een X-thorax -Patiënt heeft Down Syndroom -Patiënt heeft een congenital/verworven hartafwijking welke normale behandeling van astma verhindert -Patiënt heeft een primaire/secundaire immuundeficiëntie -Patiënt heeft een aangetoonde chronische longafwijking, waarvan bekend is dat deze astma "imiteert": Taaislijmziekte, Bronchopulmonaire dysplasia, Bronchiolitis obliterans |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary outcome variable is (reduction of) asthma score (Qureshi) 1 hour after administration of loading dose in the intervention group compared to the placebo group. Based on expert opinion, we consider a reduction of 2 points to represent a clinically relevant improvement. |
De primaire uitkomstmaat is astma score (Qureshi) 1 uur na toediening van oplaaddosis in de interventiegroep, vergeleken met de placebo groep. Gebaseerd op informatie van experts zien wij een vermindering van 2 punten in deze score als een klinisch relevante verbetering. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
