title: Dexmedetomidine versus propofol in dilatation and curettage: An open-label pilot randomized controlled trial.
abstract: BACKGROUND
  Traditionally propofol has been used for providing sedation in dilatation and curettage (D and C). Recently, dexmedetomidine has been tried, but very little evidence exists to support its use.
  
  
  OBJECTIVE
  The aim was to compare hemodynamic and recovery profile of both the drugs along with a degree of comfort experienced by patients and the usefulness of the drug to surgeons.
  
  
  METHODS
  Tertiary care center and open-label randomized controlled trial.
  
  
  METHODS
  Patients posted for D and C were enrolled in two groups (25 each). Both groups received fentanyl 1 μg/kg intravenous (IV) at the beginning of the procedure. Group P received IV propofol in dose of 1.5 mg/kg over 10-15 min and Group D received dexmedetomidine at a loading dose of 1 μg/kg over 10 min, followed by 0.5 μg/kg/h infusion until Ramsay sedation score reached 3-4. Hemodynamic vitals were compared during and after the procedure. In the recovery room time to reach modified Aldrete score (MAS) of 9-10 and patient's and surgeon's satisfaction scores were also recorded and compared.
  
  
  RESULTS
  In Group D, patients had statistically significant lower heart rate at 2, 5, 10 and 15 min as compared to Group P. Hypotension was present in 52% in Group P and 4% in Group D (P < 0.05). MAS of 9-10 was achieved in 4.4 min in subjects in Group D in contrast to 16.2 min in Group P (P < 0.05). Group D showed higher patient and surgeon satisfaction scores (P < 0.05).
  
  
  CONCLUSIONS
  Dexmedetomidine provide better hemodynamic and recovery profile than propofol. It can be a superior alternative for short surgical day care procedures.
