Outcome Measures

Primary Outcomes (1)

  • variable is to compare the sedation effect between Nalbuphine and Dexmedetomidine.

    3- Sedation score: sedation will be monitored immediately after examination, at PACU admission, and 30 min after procedure by Ramsay Sedation Scale (RSS; 1974) The RSS scores sedation at six different levels, according to how rousable the patient is. 1. Patient is anxious and agitated or restless, or both. 2. Patient is cooperative, oriented and tranquil. 3. Patient responds to commands only. 4. Patient exhibits brisk response to light glabellar tap or loud auditory stimulus. 5. Patient exhibits a sluggish response to light glabellar tap or loud auditory stimulus. 6. Patient exhibits no response

    before the study drug administration (baseline), after the study drug administration ,Then every 5min till the examination ends,at PACU admission, and 30 min after procedure.

Secondary Outcomes (1)

  • variables are the hemodynamic comparison, pain score assessment and adverse event among two groups.

    before the study drug administration (baseline), after the study drug administration ,Then every 5min till the examination ends,at PACU admission, and 30 min after procedure.

Study Arms (2)

Group I

EXPERIMENTAL

Receive initial loading dose of (Dexmedetomidine 1 μg/kg I.V) diluted up to 10 ml with normal saline infused over 10 min, followed by a continuous infusion of 0.2-0.8 μg/kg/h through a 50 ml syringe and an electronic infusion pump

Drug: Dexmedetomidine Injection [Precedex]

Group II

EXPERIMENTAL

Receive (Nalbuphine 0.1 to 0.2 mg/kg I.V) diluted up to 10 ml with normal saline infused slowly over 10 min.

Drug: Dexmedetomidine Injection [Precedex]

Interventions

intravenous dexmedetomidine for group I and nalubphine for group II in colposcopy

Also known as: nalbuphine
Group IGroup II
