Study summary

The purpose of this study is to evaluate the effectiveness of nebulized lidocaine before Endotracheal suctioning (ETS) compared to instilled lidocaine and the effectiveness of aerosolized lidocaine versus instilled normal saline before ETS in attenuating the increase of intracranial pressure (ICP) in severe head injured children and to evaluate the feasibility of a trial involving instilled lidocaine and aerosolized lidocaine for the management of ETS and to evaluate the safety of nebulized lidocaine in traumatic brain injury (TBI) compared to instilled lidocaine and instilled sodium chloride (NS).

Interventions

  • Drugaerosolized 2% lidocaine (20mg/ml)

    The aerosolized solution to be used is 2% lidocaine (20 mg/ml) at a dose of 1.5 mg/kg with a maximum volume of 3 ml or adjusted to a volume of 3 ml with addition of NS solution.The aerosolized solution will be administered with an Aerogen ultrasonic nebulizer, which is standard of care for administering aerosolized solutions in our pediatric intensive care unit (PICU).After each treatment a 3-minute interval will be allowed prior to ETS and there will be a 4-6 hour wash out period between each treatment.

  • Druginstilled 0.9% sodium chloride (NS)

    The instilled solution will be given with a standard 3-5 ml syringe.After each treatment a 3-minute interval will be allowed prior to ETS and there will be a 4-6 hour wash out period between each treatment.

  • Druginstilled 2% lidocaine solution

    The instilled 2 % lidocaine solution used will be 1.5 mg/kg, with a max volume of 3 ml or adjusted to a volume of 3 ml with addition of NS solution.The instilled solution will be given with a standard 3-5 ml syringe.After each treatment a 3-minute interval will be allowed prior to ETS and there will be a 4-6 hour wash out period between each treatment.

  • ProcedureEndotracheal Suctioning (ETS)

    ETS will be performed in a single pass using a closed-system suctioning. Suction will be applied only on withdrawal of the catheter and fraction of inspired oxygen (FIO2) will remain at 100% for 60 seconds following suctioning and then returned to the preprocedural level (baseline).

What researchers measure

Primary outcomes

  1. Change From Baseline Intracranial Pressure (ICP) at 2, 5 and 15 Minutes.

    A Codman Intraparenchymal Catheter will measure the ICP. The ICP will be transduced and measured numerically and continuously in real time on the patient's bedside monitor. ICP Values were recorded at baseline and at 2, 5, and 15 minutes after administration of aerosolized lidocaine, instilled saline solution, or instilled lidocaine solution. Change from baseline is calculated at post intervention time point.

    Time frame: Baseline and 2, 5, and 15 minutes post-intervention

Secondary outcomes

  1. Number of Patients With Worsening Respiratory Dynamics

    This will be measured by increasing oxygenation index or worsening compliance, measured by any increase in the peak pressure for volume ventilated patients.

    Time frame: from baseline to up to 15 minutes after ETS
