Abstract

Background: Conscious sedation is a technique of providing analgesia, sedation and anxiolysis while ensuring rapid recovery without side effects. Conscious sedation is administered with the dual goals of rapidly and safely establishing satisfactory procedural condition for the performance of therapeutic or diagnostic procedures while ensuring rapid, predictable recovery with minimal post-operative sequels. Dexmedetomidine is a highly selective alpha-2 agonist that provides anxiolysis and cooperative sedation without respiratory depression. It inhibits the release of norepinephrine via actions on the alpha2A (α-2A) adrenoceptors located in the locus ceruleus and the spinal cord, resulting in sedation and analgesia via sympatholysis.
Objective: It was to study the effect of dexemdetomidine with fentanyl versus ketamine with fentanyl on hemodynamic stability and recovery during conscious sedation in dilatation and curettage procedure. The comparison included the vital data and recovery time. The effect of the drugs on hemodynamics and monitoring the occurrence of any complication were also done.
Patients and Methods: In our study, 50 patients were randomly divided into 2 equal groups; group DF received dexmedtomidine loading dose 1 μg/kg over 10 min and followed by 0.5 μg/kg/hr infusion till completion of surgery and group KF received ketamine 0.5 mg/kg slow intravenous Bolus.
Results: Dexmedetomidine is a safe drug with good hemodynamic and recovery time, also exerts sedative and analgesic effects without respiratory depression, unlike most analgesic/sedative drugs, such as ketamine, opioids, benzodiazepines, and propofol.
Conclusion: This study demonstrates that dexmedetomidine is a safe drug with good hemodynamic and recovery profile. Dexmedetomidine better preserved MBP and SpO2.
