Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome is the increase in Systolic Blood Pressure (SBP), or Mean (MAP) after laryngoscopy, objectified by a difference in SBP (DiffPAS = PASmax - PAS (T1)) or a difference in MAP ( DiffPAM = PAMmax - PAM (T1)) greater than or equal to 20 mm / Hg between groups in the five minutes after the start of laryngoscopy. | — |
Secondary
| Measure | Time frame |
|---|---|
| We will observe the difference in Heart Rate (DiffFC = HRmax - HR (T1)), i.e. the difference between the peak heart rate and the heart rate before the start of laryngoscopy) greater than or equal to 20 bpm.;We will observe the onset of major cardiac events: myocardial ischemia objectified by a change in the ST segment, arrhythmias (atrial and ventricular arrhythmias, bradycardia) and asystole.;Postoperative laryngeal morbidity, including sore throat and hoarseness, will be assessed by a different anesthesiologist from the one who performed the laryngoscopy. The score to be used have four levels of assessment: 0 = absent, 1 = mild, 2 = moderate, 3 = severe | — |
