- Subanesthetic dose of intravenous ketamine with lignocaine is non-inferior to scalp block in blunting the hemodynamic responses to skull pin application for craniotomy.
Overview
Brief Summary
Application of skull pin head holder in craniotomies is routinely used which elicits a roboust sympathetic response which has the potential to affect the homeostasis negatively one of the principles of anaesthesia is to ensure adequate analgesia and patients undergoing surgeries will be voluntarily enrollled after they meet the inclusion criteria and will be randomised into two groups one with intravenous lignocaine and ketamine whilst the other into scalp block group
hemodynamic changes will be noted when the skull pin head holder is applied and intermittently until the next fifteen minutes.

Outcomes
Primary Outcomes
Subanesthetic dose of intravenous ketamine with lignocaine is non-inferior to scalp block in blunting the hemodynamic responses to skull pin application for craniotomy.
Time Frame: The heart rate and blood pressure will be measured in both the groups of patient immediately after application of skull pin head holder and there after at 1 minute 2 minutes 5 minutes 10 minutes and 15 minutes
Secondary Outcomes
- Quantifying the requirement of rescue intravenous fentanyl boluses in both the groups(At the end of 15 minutes after the application of skull pin head holder)
