Summary

The investigators are comparing the efficacy of three different sedative agents in gastrointestinal endoscopic procedures.

Conditions

  • Upper Gastrointestinal Endoscopy
  • Anesthesia

Interventions

DRUG

Dexmedetomidine and propofol

Dexmedetomidine infusion syringe (50mls): will be filled with 2mls of dexmedetomidine (200µg) diluted in 48 ml of 0.9% normal saline to make a final volume of 50mls and a final dexmedetomidine concentration of 4µg/ml. It will be infused as 1µg /kg/hr iv. Propofol infusion syringe (50mls): will be filled with 20mls of 1% propofol (200mg) diluted in 30mls 0.9% normal saline to make a final volume of 50mls and a final propofol concentration of 4mg/ml. It will be iv administered as 0.5 mg/kg slow iv for 10 minutes, then infused at a rate of 0.5mg/kg/hr.

DRUG

Midazolam and propofol

Midazolam infusion syringe (50mls): will be filled with 10mls of Midazolam (50mg) diluted in 40mls 0.9% normal saline to make a final volume of 50mls to reach a final midazolam concentration of 1mg/ml. It will be administered as a bolus dose of 0.05 mg/kg iv over 2 minutes then infused at a rate of 0.025mg/kg/hr. Propofol infusion syringe (50mls): will be filled with 20mls of 1% propofol (200mg) diluted in 30mls 0.9% normal saline to make a final volume of 50mls and a final propofol concentration of 4mg/ml. It will be iv administered as 0.5 mg/kg slow iv for 10 minutes, then infused at a rate of 0.5mg/kg/hr.

DRUG

ketamine and propofol

Ketamine infusion syringe (50mls): will be filled with 2mls of ketamine (100mg) diluted in 48mls 0.9% normal saline to make a final volume of 50mls to reach a final ketamine concentration of 2mg/ml. It will be administered as a bolus dose of 0.25 mg/kg iv then infused at a rate of 0.25mg/kg/hr. Propofol infusion syringe (50mls): will be filled with 20mls of 1% propofol (200mg) diluted in 30mls 0.9% normal saline to make a final volume of 50mls and a final propofol concentration of 4mg/ml. It will be iv administered as 0.5 mg/kg slow iv for 10 minutes, then infused at a rate of 0.5mg/kg/hr.
