ABSTRACT

Background: The present study examined the effect of bilateral infraorbital nerve block with marcaine on hemodynamic changes during sinus endoscopic surgery. Material and Methods: 30 patients underwent sinus endoscopy surgery in two groups: marcaine and normal saline. Ifraorbital nerve block was performed in the first group by injecting 1 ml of 0.5% marcaine for 30 to 40 seconds and in the second group by injecting 1 ml of sterile normal saline. The level of oxygen, pulse rate, and systolic and diastolic blood pressure were measured before anesthesia, 30 minutes and 60 minutes after anesthesia, at the time of completion of recovery surgery and exit from recovery. Results: The mean age of men was 37.29±10.15 and the mean age of women was 38.92±7.60. The mean systolic blood pressure of the marcaine group was less in comparison with the normal saline group 30 minutes (p = 0.001) and 60 minutes after the start of the anesthesia process, as well as at the time of surgery, at the time of entering the recovery and at the time of leaving the recovery (p <0.001). The mean pulse rate of marcaine group was less than normal saline group 30 minutes (p = 0.005) and 60 minutes (p = 0.019) after the start of anesthesia and at the end of surgery (p = 0.007). Conclusion: Bilateral infraorbital nerve block with topical injection of marcaine has a greater effect on lowering systolic and diastolic blood pressure and pulse than normal saline injection.
