Abstract
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.

Studying the effect of intravenous dexmedetomidine on hemodynamic parameters in patients undergoing septorhinoplasty surgery

Volume 82, Issue 11 (February 2025)
Abstract
Background: Hemodynamic instability is a significant perioperative complication that can threaten surgical outcome through various mechanisms: exacerbating intraoperative bleeding, compromising visibility of the surgical field, and elevating immediate and delayed postoperative complication risks. In septorhinoplasty, a procedure with challenging hemodynamic control due to the nasal anatomy's complexity of vessels, these effects are particularly relevant. This study examines the modulation of important hemodynamic parameters (SBP, DBP, MAP, HR, and SpO₂) by intravenous dexmedetomidine while ensuring cardiovascular stability and dose-dependent effects and optimal timing of administration at different phases of surgery. The findings aim to offer evidence-based recommendations for hemodynamic control in rhinoplasty surgery, which can reduce rates of complications and improve recovery profiles.
Methods: A randomized, double-blind clinical trial was conducted involving 50 eligible patients (aged 18-45 years) scheduled for septorhinoplasty at Ostad Motahari Hospital, Jahrom, during May-September 2023. Participants were randomly allocated to either a dexmedetomidine or control group. Collected data encompassed demographic characteristics (age, gender, BMI=Body mass index) and hemodynamic parameters (systolic/diastolic blood pressure, mean arterial pressure, heart rate, and oxygen saturation). The data were analyzed using SPSS software, version 21 (SPSS Inc., Chicago, IL, USA). Descriptive statistics (mean, standard deviation, percentage, count, and frequency) and inferential statistical tests (Mann-Whitney U test and independent t-test) were applied. A significance level of P < 0.05 was considered for all statistical analyses.
Results: The dexmedetomidine group demonstrated statistically significant variations in hemodynamic parameters (SBP, DBP, MAP, HR) from pre-induction through post-recovery phases (p<0.001). Significant between-group differences in blood pressure metrics were observed at all measured intervals following induction (1, 5, 15, 30, 60 minutes) and during recovery periods (p<0.05), with the dexmedetomidine group consistently showing lower values. Comparison between the intervention and control groups revealed no statistically significant differences in heart rate and oxygen saturation (O₂ sat) levels (except during recovery time).
Conclusion: The results of this study indicate that dexmedetomidine administration had a significant effect on reducing systolic blood pressure, diastolic blood pressure, and MAP compared to the control group, with this reduction being evident at all measured time points from post-induction to post-recovery. These findings suggest that dexmedetomidine can be effectively used as a blood pressure-lowering agent during surgery without significantly affecting heart rate or the patient's blood oxygen levels.

Volume 83, Issue 6 (September 2025)
Abstract
Background: In general anesthesia, anesthetic agents are administered by inhalation or intravenously, leading to loss of consciousness, immobility, analgesia, and amnesia. In spinal anesthesia, injection of a local anesthetic into the intrathecal space causes sensory and motor block. The aim of this study was to compare the volume of bleeding during cesarean section under general anesthesia and spinal anesthesia.
Methods: This study is a cross-sectional prospective study. The gauzes used were weighed before the operation and bloody gauzes were weighed after the operation. The difference between the weight of bloody and dry gauzes was recorded as the volume of bleeding. This volume was then added to the volume of blood in the suction chamber and the final bleeding volume was estimated.
Results: 70 patients who were candidates for cesarean section were included in the study. The mean age of the patients included in the study was 24.82±4.98 and their mean weight was 77.11±8.97. The mean hemoglobin in the spinal anesthesia group was 91.12±39. Volume of bleeding during cesarean section by spinal anesthesia was significantly less than general anesthesia (P=0.001). Also, the visual estimation of bleeding in spinal anesthesia was significantly lower than general anesthesia (P<0.001). In this study, there was no significant difference between heart rate, systolic and diastolic pressure before and during surgery, and the first- and fifth-minute Apgar scores between the two groups of general and spinal anesthesia.
Conclusion: We found in this study that the volume of bleeding during cesarean section under spinal anesthesia is less than general anesthesia. It is suggested that in future studies, other methods of estimating bleeding such as postoperative hemoglobin reduction, dilution method, atomic absorption spectroscopy and photometry be used. Also, a comparison should be made between the three groups of general, spinal and epidural anesthesia, and the volume of bleeding in each should be checked and the best anesthesia method should be selected for cesarean section.
