Brief Summary

This randomized double-blind study aimed to compare the effects of dexmedetomidine and ketamine on hemodynamic parameters, recovery criteria, and opioid consumption and advers effects in septorhinoplasty operations. Totally 63 patients were included.

The groups were compared in terms of hemodynamic values, recovery times, postoperative agitation, sedation, activity, modified Aldrete and pain scores, side-effects and additional analgesia requirements at postoperative 24h.

• Detailed Description: A total of 63 patients 18-55 years undergoing septorhinoplasty, who were graded as American Society of Anesthesiologists physical status were randomly allocated into three groups, receiving dexmedetomidine (n=21, Group D), ketamine (n=21, Group K) and saline solution (n=21, Group S). Anesthesia was induced with propofol, cisatracurium and fentanyl. Maintenance anesthesia was done with 2-2.5% sevoflurane mixture, 50-60% oxygen and N2O. The groups were compared in terms of hemodynamic values, recovery times, postoperative agitation, sedation, activity, modified Aldrete and pain scores, side-effects and additional analgesia requirements at postoperative 24h.

Study Design

Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description:

1. First arm received dexmedetomidine
2. Second arm received ketamine
3. Third arm received saline solution.

Masking: Triple (Participant, Care Provider, Investigator)
Masking Description:

Primary Purpose: Treatment

Condition

• Anesthesia
• Intravenous Anesthetic Toxicity

Intervention

• Drug: Dexmedetomidine
  dexmedetomidine was administered as a gradual bolus of 1 µg/kg/10ml 10 min before induction of anesthesia and then as an infusion of 0.4 µg/kg per min (30 ml/h). In Group K, ketamine was administered as a 0.4 mg/kg/10ml IV bolus 10 min before induction of anesthesia and in the form of 10 µg/kg per min infusion after induction (30 ml/h).
  Other Name: Group D
• Drug: Ketamine
  In Group K, ketamine was administered as a 0.4 mg/kg/10ml IV bolus 10 min before induction of anesthesia and in the form of 10 µg/kg per min infusion after induction (30 ml/h).
  Other Name: Group K
• Drug: Saline
  Group S was given a bolus of saline solution in 10 ml volume 10 min before induction of anesthesia, followed by 30 mL/h serum saline infusion.
  Other Name: Group S
