Summary

104 patients who undergo painless colonoscopy from January 20,2024 to February 29,2024 will be randomized to two groups: propofol group and dexmedetomidine group.

In the dexmedetomidine group,dexmedetomidine is infusion intravenously with a loading dose of 0.5 μg kg-1 for 10 min, then infusion at 0.3 μg kg-1 h-1 according to the ideal body weight of the patient until the end of colonoscopy. In the propofol group, Propofol is administrated 1 mg kg-1 intravenously, then titrated given by 0.5 mg kg-1 during the whole process.

Conditions

  • Colonoscopy

Interventions

DRUG

Dexmedetomidine

In the dexmedetomidine group, dexmedetomidine is infusion intravenously with a loading dose of 0.5 μg kg-1 for 10 min, then infusion at 0.3 μg kg-1 h-1 according to the ideal body weight of the patient until the end of colonoscopy. During the whole process, maintenance Ramsay score of 3 to 4. Propofol 10 mg will be administrated as the rescue dose if body movement occur during colonoscopy.

DRUG

Propofol

Propofol is administrated 1 mg kg-1 intravenously, then titrated given by 0.5 mg kg-1 until Ramsay score reach 3. During the whole process, propofol is given intermittently to maintain Ramsay score 3 to 4. If body movement happen, propofol 10mg will be administrated every time.
