Abstract: (35 Views)

Background: Rhinoplasty is a challenging and complex surgery because it is designed to meet the unique needs of the patient. In rhinoplasty surgery, many factors contribute to achieving the desired result. These factors include the surgeon's care and observation, analysis of the existing anatomy, choice of surgical technique, degree of soft tissue and cartilage trauma, amount of bleeding, quality of surgical instruments and anesthesia, and anything that helps reduce bleeding.
Methods: This double-blind study was conducted on 50 patients aged 18 to 45 years undergoing septorhinoplasty surgery referred to Motahari Hospital in Jahrom city in 2022. Patients were randomly divided into dexmedetomidine and control groups. The degree of sedation, bleeding and surgeon satisfaction were evaluated and recorded. Data analysis was performed using SPSS software, version 21 (IBM SPSS, Armonk, NY, USA) and descriptive statistics (mean, standard deviation, percentage, number, frequency) and inferential statistical tests (Mann-Whitney U test, Kruskal-Wallis, t-test, chi-square test). The significance level in all tests was considered P<0.05.

Results: The majority of patients in the study groups were female and the mean age of patients in the dexmedetomidine group was 34.36±7.33 years and in the control group was 36.60±9.59 years. The study groups were similar in terms of age and body mass index (P<0.05). The frequency of patient sedation in the dexmedetomidine group was lower than the control group, but it was not statistically significant (P<0.05). The results showed that at the beginning of the operation and 90 minutes later, the satisfaction level of the patient surgeon in the dexmedetomidine group was significantly better than the control group (P<0.001). In the dexmedetomidine group, the field of view of the surgeon was relatively clear and completely clear. The amount of bleeding in the dexmedetomidine group was lower than the control group, but it was not statistically significant (P<0.05).
Conclusion: Dexmedetomidine increased the surgeon's satisfaction by reducing bleeding and improving the surgeon's visual field. Therefore, this drug can be used as an anesthetic aid in surgery.

Keywords: dexmedetomidine, bleeding, randomized controlled trial, rhinoplasty, sedation.
