Abstract :
Background: Dilatation and curettage (D and C) is an essential and common minor surgery in obstetrics and gynecology. Sedation, hypnosis and analgesia are used in combination for such short procedures. These days conscious sedation is provided to patients for day care surgeries which includes analgesia, sedation and anxiolysis while rapid recovery is ensured without side effects. Dexmedetomidine is a highly selective alpha-2 agonist that provides anxiolysis and conscious sedation without respiratory depression.
Objective: It was to study the effect of dexemedetomidine with fentanyl versus Pentazocine with promethazine on hemodynamic stability and recovery during sedation in dilatation and curettage procedure. The comparison included the hemodynamic data and recovery time. The effect of the drugs on hemodynamics and monitoring the occurrence of any complication were also done.
Materials and Methods: In our study, 50 patients were randomly divided into 2 equal groups; group DF received dexmedetomidine loading dose 1 ?g/kg over 10 min and followed by 0.5 ?g/kg/hr infusion till completion of surgery and group PP received pentazocine 0.5 mg/kg (max 30mg) and Promethazine 12.5 mg slow intravenous Bolus.
Results: Dexmedetomidine is a safe drug which provides good hemodynamics and less recovery time. It also exerts sedative and analgesic effects without respiratory depression unlike most analgesic/sedative drugs, such as ketamine, pentazocine and benzodiazepines.
Conclusion: This study demonstrates that dexmedetomidine is a safe drug with good hemodynamic and recovery profile. Dexmedetomidine administration showed better preservation of MAP and SpO2.
