Abstract
WHAT IS KNOWN AND OBJECTIVE: The most appropriate sedative agent for conscious sedation in minor hysteroscopic surgeries is still unclear. Dexmedetomidine a sedative and analgesic agent, may be appropriate for outpatient procedures. The aim of our study was to compare the sedative, analgesic and hemodynamic effects of dexmedetomidine vs propofol in combination with fentanyl and midazolam in patients undergoing minor hysteroscopy surgery. METHODS:Sixty patients undergoing minor hysteroscopic surgery were randomized to receive either dexmedetomidine (n = 30) or propofol (n = 30) groups. Dexmedetomidine was infused at 1 µg/kg for 10 minutes followed by a 0.7 µg/kg/h maintenance infusion. Propofol was infused a bolus of 1.5 mg/kg followed by a 2.5 mg/kg/h maintenance infusion. Fentanyl 1.5 mcg/kg and midazolam 0.03 mg/kg were performed to all patients as premedication therapy before the hysteroscopic surgery. Post-operative pain score was assessed with visual analogue scale (VAS). Hemodynamic variables and Riker Sedation-Agitation Scale (SAS) scores were recorded for all patients. RESULTS:Mean arterial pressure and heart rate in the dexmedetomidine group were significantly lower than in propofol group, whereas SpO2 was similar between two groups. In addition, post-operative Riker SAS and VAS scores were significantly lower in dexmedetomidine group than in the propofol group. Bradycardia, hypotension and serious adverse events did not occur in any patients. WHAT IS NEW AND CONCLUSION: Dexmedetomidine was associated with better analgesia and lower post-operative pain score than propofol in patients undergoing hysteroscopic surgery. However, arterial pressure and heart rate should be more closely monitored in patients received dexmedetomidine.
