NCT03480880

Brief Summary

This study was conducted in two parts:

  1. 1.This first part was designed to determine thiopentone dose requirement for induction of anaesthesia with and without the use of Bispectral Index monitoring - Participant and Care Provider in appropriate study arm blinded.
  2. 2.As a secondary outcome, Bispectral index monitoring was used to observe changes in neuronal function in intraoperative period as well as haemodynamic changes intraoperatively - Participant and Care Provider blinded.

Outcome Measures

Primary Outcomes (1)

  • Thiopentone requirement

    Difference of thiopentone requirement with and without use of Bispectral Index guidance during induction of anaesthesia in traumatic brain injury patients.

    Beginning of anaesthetic induction till End of anaesthetic induction

Secondary Outcomes (4)

  • Intraoperative Bispectral Index changes

    Beginning of anaesthetic Induction till patient is shifted to post-anaesthesia care unit.

  • Intraoperative Systolic blood pressure changes

    Beginning of anaesthetic Induction till patient is shifted to post-anaesthesia care unit.

  • Intraoperative Mean blood pressure changes

    Beginning of anaesthetic Induction till patient is shifted to post-anaesthesia care unit.

  • Intraoperative heart rate changes

    Beginning of anaesthetic Induction till patient is shifted to post-anaesthesia care unit.

Study Arms (2)

Group BIS

EXPERIMENTAL

Thiopentone dosing during induction of anaesthesia based on guidance of Bispectral Index values.

Device: Bispectral Index

Group Clinical

NO INTERVENTION

Thiopentone dosing during induction of anaesthesia based on clinical guidance targeted to loss of eyelash reflex or loss of response to noxious stimulus.

Interventions

Thiopentone was administered in 50 mg boluses during induction of anaesthesia, until reduction of Bispectral Index value to less than 50, and total dose of thiopentone recorded.
