Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention: 2% lidocaine
Doses: lidocaine 1.5 mg/kg added to normal saline (total volume of 5 mL)
Mode of administration: endotracheal instillation
Duration: instillation at 1 ml/s rate
Each study will be performed in duplicate, once after endotracheal lidocaine instillation and once after instillation of an equal volume of a normal saline in a double-blind crossover fashion. Lidocaine and saline will be instilled at body temperature through a 4-French fine tube advanced into the endotracheal tube within its length, near the carina. Approximately 30-60 secs prior to suctioning procedure, the delivery of FiO2 will be increased to 100% while the ventilator settings will remain unchanged. After endotracheal lidocaine or saline solution instillation a 3 min interval will be allowed prior to the suctioning event which will be performed in a single pass using an closed-system suctioning (with an appropriate diameter of the suction catheter, negative pressure of 80-100 mmHg, and total duration of < 15 secs). Inspired oxygen fraction (FiO2)will remain at 100% for 60 secs following the suctioning event then will be returned to the preprocedural level (baseline). After a 3 hour-washout period the crossover solution will be then administered

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation involved contacting the holder of the allocation schedule (study pharmacist) who was "off-site" (Department of Pharmacy) and had no contact with the study participants
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation by using a randomization table created by a computer software (i.e. computerised sequence generation)
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s
The people administering the treatment/s
The people assessing the outcomes
The people analysing the results/data

Efficacy
Statistical methods / analysis
To detect a 15% change in intracranial pressure from baseline with an SD of 5 mm Hg and an a risk of 0.05 and a ß risk of 0.2, the size of the study population needed to be at least 13 patients for a cross-over design.
Continuous data are reported as a mean and standard deviation (SD) and analyzed with an unpaired Student’s t-test. To compare the intracranial pressure changes between the two drugs during study period, mean differences with 95% confidence intervals (95% CIs) will be reported. Repeated-measures analysis of variance will be used to test for within-group differences followed with t test with Bonferroni correction..
All analysis will based on the intention-to-treat principle . Calculations will be performed by using the SPSS ( statistical packages (SPSS Inc., Chicago, IL), applying 2-sided Fisher exact tests for comparisons of categorical data, and Mann–Whitney U tests for continuous data. Differences will be considered statistically significant at p < 0.05

Summary
Brief summary
Endotracheal suctioning (ETS) is an essential nursing and physiotherapy activity in intensive care that needs to be frequently repeated in intubated patients to reduce morbidity associated with invasive ventilation. However, research has shown that ETS can have considerable negative impact on many physiological variables, including the intracranial pressure (ICP) and cerebral perfusion pressure (CPP) of head-injured patients. Studies in adults have demonstrated a significant supression of ICP elevation with lidocaine administered intratracheally. However, there is a lack of pediatric studies assessing the issue of endotracheal lidocaine instillation for blunting endotracheal suctioning-induced ICP changes. The primary objective of this study is to evaluate the effectiveness of endotracheal lidocaine instillation at dosage of 1.5 mg/kg in reducing the increase of ICP after a single endotracheal suctioning in severe head-injured children.
