Septorhinoplasty is a common cosmetic surgery nowadays. Local anaesthetic mixture with adrenaline was preferably used for obtaining bloodless surgical field and adequate perioperative analgesic strategy. Dexmedetomidine as a selective α2-agonist may be useful as an additive agent that helps in achieving a suitable surgical field and postoperative proper pain management. Patients and method: Eighty patients who were scheduled for elective septorhinoplasty umder general anesthesia were divided into two groups, each included 40 Patients. Group I: patient received local anaesthesia and adrenarline, group II: patient received the same as group I besides dexmedetomidine 100 µg. Heart rate, mean arterial blood pressure changes were monitored. Surgical and operative times were reported. The level of sedation and postoperative pain were evaluated by Ramsay Sedation Scale (RASS) and Visual Analogue Scale (VAS) respectively. The amount of analgesic requirement and the time till first analgesic requirement were also recorded. Surgeon and Patients' satisfaction with anesthesia were questioned one week after discharge. Results: Heart rate and mean arterial blood pressure were significantly decreased in group II compared with group I. RASS score was higher and VAS score and bleeding was lower in group II compared to group I. Surgeons and patients satisfaction was higher in group II compared to group I. Conclusion: In conclusion, supplementation of local anesthesia with dexmedetomidine produces an adequate level of intraoperative hemodynamic stability, conscious sedation, adequate analgesia, low postoperative analgesic requirements with extended pain free period and less bleeding in all patients. These effects are well obtained with high dose of dexmedetomedine.
