Abstract

Objective: Hemostasis during endoscopic sinus surgery is one of the critical factors, contributing the success of the surgery. Vasoconstrictor effect on the nasal mucosa by placing topical Adrenaline has been widely used in the world, but not in Viet Nam. Therefore, we conducted a study to evaluate the effectiveness and safety of local Adrenaline 1:1000 application in endoscopic sinus surgery. Patients and Methods: This is a case series study. Patients with chronic rhinosinusitis who underwent endoscopic sinus surgery under general anesthesia were included. The nasal cavities were packed with Adrenaline 1:1000-impregnated wicks for 5 minutes before starting the surgery. The volume of blood loss, Boezaart surgical field grading scale, heart rate, systolic blood pressure, diastolic blood pressure, and mean arterial pressure were recorded after general anesthesia before and after inserting the wicks at 1 minute, 3 minutes, 5 minutes, 10 minutes, and every 10 minutes until the surgery was finished. Results: 31 patients were included in the study. The average volume of blood loss was 377.41 ± 271.05 mL, and no cases of severe bleeding requiring blood transfusion were observed. Mild bleeding accounted for 77.5% of cases, while moderate bleeding accounted for 22.5% according to the Boezaart field grading scale. The heart rate increased by 1.97 ± 6.59 beats per minute after applying the wicks for 1 minute, slightly increased after 3 minutes and 5 minutes, and then decreased after 10 minutes and in the recovery room. No arrhythmia was noted. Systolic and diastolic blood pressure increased slightly after inserting the wicks for 1 minute and 3 minutes, but still remained within safe limits. No cardiovascular complications were observed during the surgery. Conclusion:  The application of topical Adrenaline 1:1000 is safe and effective in endoscopic sinus surgery. It helps to create a clear surgical field, reduces intra-operative bleeding, and does not significantly affect hemodynamics during the surgery.
