Regional anesthesia combined with general anesthesia for minimally invasive procedures has become a common anesthetic technique. The goal of this approach is to reduce pain and promote rapid recovery [If regional anesthesia facilitates the administration of less systemic pain medications, patients could benefit in several ways: (1) reduced postoperative discomfort and opioid use, (2) decreased postoperative nausea and vomiting, (3) shortened PACU (post-anesthesia care unit) stay time, and (4) shortened time to discharge from hospital. A more streamlined, shorter, and more pleasant hospital course for the patient could lead to increased patient satisfaction and potential economic gains for the hospital.Pituitary tumor surgery is primarily executed through a minimally invasive approach through the nose and sinuses as an endoscopic procedure called the: “Trans-Sphenoidal Hypophysectomy”. More recently, it has been performed entirely endoscopically through the nose as the earlier modification, the “Caldwell Luc” approach, involved opening a bony window through a sub-labial oral (at the upper gum line under the top lip), leading to the maxillary sinus and then ultimately to the sellar cavity housing the pituitary tumor. Patients who undergo this endonasal endoscopic trans-sphenoidal pituitary surgery are usually same-day admission patients who, following their operation, stay in a hospital up to 24 hours postoperatively. Prolonged post-op admissions are often caused by persistent headaches or nausea with or without vomiting [
