Summary

Comparision of Exposed Factors of Preoperative Hypertension and Intraoperative Controlled Hypotension on Postoperative Delirium in the Elderly under Radical Resection of Head, Neck and Maxillofacial Tumor

Detailed description

Postoperative delirium has a higher incidence in elderly patients after general anesthesia，and It is closely related to the type of surgery, the length of surgery, and the patient's physique.Because head and neck maxillofacial radical surgery requires free flap transplantation and longer duration,and hemorrhage is more when the primary focus is removed，Intraoperative blood pressure reduction is needed to reduce bleeding，therefore, hypoperfusion of craniocerebral blood flow will occur.Low cerebral perfusion is closely related to the occurrence of postoperative delirium.Patients undergoing this type of surgery have more preoperative complications，hypertension is particularly common.Therefore, this study mainly studied the correlation between the preoperative blood pressure level and the controlled hypotension level in patients with radical head and neck and maxillofacial tumors and the incidence of postoperative delirium.
