Dexmedetomidine Infusion Dose Versus Rapid Bolus Dose Before Tracheal Intubation.

NCT06327399 | Recruiting Phase 2

• 1 other identifier: MS-373-2023
• Study Type: interventional
• Target: 70
• Locations: 1 country
• Sites: 1

Brief Summary

Dexmedetomidine bolus dose may provide similar or less hemodynamic changes (less bradycardia and less hypertension) than infusion dose during induction of anaesthesia and tracheal intubation.

Conditions

Dexmedetomidine; Intubation Complication

Outcome Measures

Primary Outcomes (1)

• Mean blood pressure upon laryngoscopy

  mean blood pressure measurement (mmhg) during laryngoscopy

  1 minute

Secondary Outcomes (3)

• Blood pressure & Heart rate

  1 min after dexmeditomedine, after induction, at intubation and 1,3,5 and 10 min after intubation

• Propfol

  induction

• Bradycardia

  from start of dexmedetomidine injection before induction till 10 minutes after intubation

Study Arms (2)

Group A

ACTIVE COMPARATOR

patients will receive Dexmedetomidine infusion dose of 1 mcg/kg over 10 min.

Drug: Dexmedetomidine infusion; Drug: Atropine Sulfate; Drug: Ephedrine; Drug: Propofol

Group B

ACTIVE COMPARATOR

patients will receive Dexmedetomidine bolus dose of 0.3 mcg/kg over 60 seconds.

Drug: Dexmedetomidine bolus; Drug: Atropine Sulfate; Drug: Ephedrine; Drug: Propofol

Interventions

Dexmedetomidine infusion DRUG

patients will receive Dexmedetomidine infusion dose of 1 mcg/kg over 10 min before induction.

Also known as: infusion

Group A

Dexmedetomidine bolus DRUG

patients will receive Dexmedetomidine bolus dose of 0.3 mcg/kg over 60 seconds.

Also known as: Bolus

Group B

Atropine Sulfate DRUG

If heart rate falls below 45 bpm, rescue dose (500 mcg) of atropine will be given.

Group A; Group B

Ephedrine DRUG

If mean blood pressure decreases below 50 mmHg, boluses of 10 mg ephedrine will be given

Group A; Group B

Propofol DRUG

Propofol 20 mg boluses till loss of contact

Also known as: induction of anethesia

Group A; Group B
