Bilateral Sphenopalatine Ganglion Block Using Prilocaine Versus Lidocaine as Adjuvants to General Anesthesia During Endoscopic Hypophysectomy, Randomized Trial.
Patients undergoing endoscopic surgeries for pituitary adenoma excision suffer from wide swings in blood pressure that might increase bleeding and interfere with the surgical field. Local anethetic infiltration and regional nerve blocks have been used to provide better analgesia, control blood pressure and improve surgical field. Limited studies evaluated shenopalatine ganglion block in pituitary adenoma excision with promising outcomes. The proposed study will compare the efficacy of two local anesthetics, prilocaine and lidocaine, for spenopalatine ganglion block in patients undergoing endoscopic pituitary adenoma excision. Evaluating the control of the intraoperative blood pressure and analgesic sparing are the main objectives of the proposed study.
• Patients with pituitary adenoma undergoing endoscopic hypophysectomy.
• ASA physical status I and II.
• Age above 21, below 45 years.
• Male or female
