Assessment of Hemodynamic Response During Intubation Between Rigid Laryngoscopy and Track Light in Coronary Patients

This study has been completed.

Opioids provide greater patient comfort during intubation, but are not able to abolish completely the release adrenergic hormones during the laryngoscopy, which may cause undesirable hemodynamic changes.

In this study the investigators selected two techniques commonly used for intubation, laryngoscopy and track light, so the investigators can verify which intubation techniques provides less hemodynamic changes in coronary patients under standard anesthesia induction.

Condition Intervention Phase
Coronary Disease Undergoing CABG
Procedure: laryngoscopy
Procedure: track light
Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Randomized Clinical Trials to Compare the Hemodynamic Response During Intubation Between Rigid Laryngoscopy and Track Light in Coronary Patients Undergoing CABG
