Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Topical lignocaine vs. placebo onto vocal cords for a laryngo-tracheo-bronchoscopy.
The lignocaine is applied directly following induction of anaesthesia. It is only applied once which takes one spray of lignocaine of 5-10 seconds duration.
The lignocaine dose used will be a maximum of 4 mg/kg as topical spray (under vision) onto the vocal cords. For this trial, lignocaine 4% will be used in all children. In children > 30 kg 3 ml of lignocaine 4% will be applied.
Intervention code [1] 256136 0
Prevention
Comparator / control treatment
Saline.
The saline is sprayed as a once off spray (identical to lignocaine) directly following induction of anaesthesia. The application of the spray takes approx. 5-10 seconds.
The control group will receive the equivalent amount of normal saline in ml as compared to the lignocaine dose
Control group
Placebo

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Written voluntary consent consisting of parental permission and also child assent when applicable, will be obtained and great care will be taken to maintain the highest standards regarding consent for clinical research in paediatric anaesthesia. The children will be included into the trial at the preanaesthetic visit. Following inclusion into the study protocol, the children will be randomly assigned to group “lignocaine” or group “saline” by computer generated block randomisation. The anaesthetist in charge, the ENT surgeon and the recovery staff will be blinded to the substance used to spray on the cords (lignocaine vs saline). Allocation was concealed in sealed opaque envelopes
