Brief Summary
Rapid sequence induction (RSI) is a standard anesthesia technique used in patients at risk of aspiration. Although tracheal intubation following RSI is a frequent and painful procedure, no study has yet evaluated nociception using the Analgesia Nociception Index (ANI) during this procedure. This monocentric prospective observational study aims to describe the impact of RSI on pain measured by ANI, and to explore early complications (desaturation, hypotension, regurgitation) and factors associated with pain and complications. 150 patients undergoing RSI in the visceral surgery operating room at CHPG Monaco will be analyzed.

Outcome Measures
Primary Outcomes (1)
Variation of the Analgesia Nociception Index (ANI) during the 5 minutes following rapid sequence intubation
5 minutes post-induction
Secondary Outcomes (6)
Variation of hemodynamic parameters (heart rate, systolic and diastolic blood pressure) during the 5 minutes post-RSI
5 minutes post-induction
Occurrence of regurgitation during RSI
5 minutes post-induction
First-attempt intubation success rate
At time of intubation
Variation of SpO2 during the 5 minutes post-RSI
5 minutes post-induction
Identification of factors associated with reduced pain (lower ANI variation)
5 minutes post-induction
- +1 more secondary outcomes
Interventions
Standard rapid sequence induction according to SFAR guidelines, with additional non-invasive ANI monitoring via cutaneous pectoral electrodes. No intervention beyond routine care; induction drug choice (hypnotic, opioid, neuromuscular blocker) at the discretion of the anesthesiologist.
