NCT05941767

Brief Summary

Laryngoscopy, tracheal intubation, surgical stimulation, and extubation unleash remarkable sympathetic activity and are associated with transient but significant hemodynamic changes. The need to blunt these noxious responses effectively has led to using several techniques and pharmacological agents, local anesthetics, beta-adrenergic-blockers, calcium channel antagonists, and opioids with varied success. This study aims to evaluate the effect of nebulized and intravenous either dexmedetomidine or lidocaine for attenuating the hemodynamic responses to laryngoscopy and intubation.

Outcome Measures

Primary Outcomes (5)

  • Change in serum cortisol levels.

    Base line blood sample will be drawn 45 minutes preoperative and 10 minutes post intubation for cortisol level measurements.

    Measurement will be done 45 minutes preoperative and 10 minutes after endotracheal intubation.

  • Change in mean arterial blood pressure (MAP) in mmHg.

    Mean arterial pressure (MAP) will be recorded 10 minutes before induction and at 1,3,5,7 and10 minutes after endotracheal intubation.

    Measurement will be done 10 minutes before induction and at 1,3,5,7 and 10 minutes after endotracheal intubation.

  • Change in heart rate (HR) per minute.

    Heart rate (HR) will be recorded 10 minutes before induction and at 1,3,5,7 and10 minutes after endotracheal intubation.

    Measurement will be done 10 minutes before induction and at 1,3,5,7 and 10 minutes after endotracheal intubation.

  • Change in systolic blood pressure (SBP) in mmHg.

    Systolic blood pressure (SBP)will be recorded 10 minutes before induction and at 1,3,5,7 and10 minutes after endotracheal intubation.

    Measurement will be done 10 minutes before induction and at 1,3,5,7 and 10 minutes after endotracheal intubation.

  • Change in diastolic blood pressure (DBP) in mmHg.

    Diastolic blood pressure (SBP)will be recorded 10 minutes before induction and at 1,3,5,7 and 10 minutes after endotracheal intubation.

    Measurement will be done 10 minutes before induction and at 1,3,5,7 and10 minutes after endotracheal intubation.
