Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention:nebulized l-epinephrine (1:1000)
Doses: 0.5 mL or 2.5 mL or 5 mL
Mode of administration: nebulization by face mask
Duration: 15 minutes
Patients will be assigened to one of three study treatments at 15 minutes post-extubation: 5 mL of l-adrenaline 1:1000 (group 1), 2.5 mL of l-adrenaline 1:1000 (group 2) or 0.5 mL of l-adrenaline 1:1000 (group 3). If the amount of l-epinephrine was less than 5 mL, isotonic saline was added until the volume achieved 5 mL. Research nurse will administer nebulizations over 15 minutes with a small, tight-fitting plastic face mask with an updraft nebulizer (Hudson RCI, Teleflex Medical, USA) connected to a source of pressurized oxygen with continuous flow of 100% oxygen at 5 L/min. The nebulizers will be administered until empty.

Outcomes
Primary outcome [1] 259172 0
Mean change in the post-extubation stridor score (Westley score). The Westley score evaluates five clinical parameters that are related to the degree of upper airway obstruction. The scoring system ranges from 0 to 17 points, with 17 points indicating the most severe stridor.
Timepoint [1] 259172 0
Timepoints: at baseline (0 minute) and at 20, 40, 60, and 180 minutes after epinephrine nebulization
Secondary outcome [1] 265516 0
respiratory rate (breaths per minute) will be continuously monitored by a multiparameter bedside monitor (DX 2020, Dixtal, Sao Paulo, Brazil)
Timepoint [1] 265516 0
at baseline (0 minute) and at 20, 40, 60, and 180 minutes after epinephine nebulization
Secondary outcome [2] 265517 0
heart rate (beats per minute) will be continuously monitored by a multiparameter bedside monitor (DX 2020, Dixtal, Sao Paulo, Brazil)
Timepoint [2] 265517 0
at baseline (0 minute) and at 20, 40, 60, and 180 minutes after epinephrine nebulization
Secondary outcome [3] 265518 0
non-invasive blood pressure (mmHg) will be monitored by a multiparameter monitor (DX 2020, Dixtal, Sao Paulo, Brazil)
Timepoint [3] 265518 0
at baseline (0 minute) and at 20, 40, 60, and 180 minutes after epinephrine nebulization
Secondary outcome [4] 265519 0
oxygen saturation (%) on pulse oximetry will be continuously monitored by a bedside multiparameter monitor (DX 2020, Dixtal, Sao Paulo, Brazil)
Timepoint [4] 265519 0
at baseline (0 minute) and at 20, 40, 60, and 180 minutes after epinephrine nebulization

Summary
Brief summary
Although the use of nebulized epinephrine has been well studied and has a long history of use in children with viral croup, there is a few prospective studies investigating the effect of epinephrine on postextubation croup. However, there is no consensus in the literature regarding the appropriate dose of nebulized 1:1000 l-adrenaline that should be used to preventing postextubation croup.
The aim of this study is to compare the effectiveness and safety of nebulized l-epinephrine at dosage of 0.5 mL, 2.5 mL and 5 mL in the treatment of postextubation stridor
