Assessment of stress response due to C-Mac D-blade guided videolaryngoscopic endotracheal intubation and docking of da Vinci surgical robot using perfusion index in patients undergoing transoral robotic oncosurgery
Authors' conclusion
As non-invasively quantified by PI, videolaryngoscopic stress response is more intense but shorter-lived versus that due to docking.

- Adults scheduled for transoral robotic surgery (TORS) under general endotracheal anaesthesiawithin-patient comparison
- Participants
- 26 adults
- Exposure
- Laryngoscopy vs Docking
- Outcome
- PI, heart rate and MAP at specific time points post-laryngoscopy and post-docking

- Laryngoscopy vs Docking: P = 0.0044 — at stressor; reported as perfusion index (PI) significantly higher at laryngoscopy
- Laryngoscopy vs Docking: P < 0.0001 — at 10 min; PI lower post-laryngoscopy
Observational data: associations, not effects.
Further findings
- PI displays a negative correlation with haemodynamic variables
- PI at laryngoscopy is a good predictor of PI at docking
