Summary

This prospective observational study aims to evaluate whether non-invasive hemodynamic parameters, including the plethysmographic variability index (PVI) and perfusion index (PI), can predict post-induction hypotension in patients undergoing diagnostic direct laryngoscopy under general anesthesia. Patients aged 18-75 years with ASA physical status I-III scheduled for elective direct laryngoscopy will be included. PVI and PI values will be recorded before anesthesia induction and in the early post-induction period. The relationship between these indices and the decrease in mean arterial pressure after induction will be analyzed to determine their predictive value for hypotension.

Conditions

  • Post-Induction Hypotension

Interventions

DEVICE

Plethysmographic Variability Index (PVI) and Perfusion Index (PI) Monitoring

Non-invasive monitoring of plethysmographic variability index (PVI) and perfusion index (PI) will be performed using pulse oximetry during the peri-induction period in patients undergoing diagnostic direct laryngoscopy under general anesthesia. These parameters will be recorded before anesthesia induction and during the early post-induction phase to evaluate their association with changes in mean arterial pressure and their predictive value for post-induction hypotension.
