Effect Of Dexmedetomidine On Controlled Hypotension In Hypertensive Patients Undergoing Endoscopic Sinus Surgery

Abstract

Abstract Nasal endoscopic surgery is a high-resolution, fine-grained procedure. With the development of nasal endoscopic surgery, the demand for a clear surgical field of vision is gradually increasing. Controlled hypotension technology can effectively reduce intraoperative bleeding and provide a clear visual field for surgery. In hypertensive patients, we use dexmedetomidine as an adjuvant on the basis of traditional nitroglycerin controlled hypotension. The experimental results show that the use of dexmedetomidine can help control blood pressure faster to the target blood pressure, while also exhibiting more stable performance during resuscitation and extubation.
