NCT05058677

Brief 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).

Outcome Measures

Primary Outcomes (1)

  • Maximum difference between baseline ICP and highest ICP levels as measured by the ICP monitor in instilled lidocaine versus nebulized lidocaine

    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.

    from baseline to upto 15 minutes after ETS

Secondary Outcomes (2)

  • Maximum difference between baseline ICP and highest ICP levels as measured by the ICP monitor in nebulized lidocaine and normal saline

    from baseline to up to 15 minutes after ETS

  • Number of patients with worsening respiratory dynamics

    from baseline to up to 15 minutes after ETS

Interventions

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.

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).

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.

Sexall
Healthy VolunteersNo
Age GroupsChild (0-17)

You may qualify if:

  • Patients admitted to the PICU of Memorial Hermann Children's Hospital
  • Severe TBI with a Glasgow Coma Scale score 4-8
  • Intubated and mechanically ventilated with an ICP monitor in place.
