COMBINED REGIONAL NASAL BLOCK AND GENERAL ANESTHESIA VERSUS GENERAL ANESTHESIA WITH INDUCED HYPOTENSION TECHNIQUE DURING ENDOSCOPIC SINUS SURGERY

Abstract

Background: Since the early development of functional endoscopic sinus surgery (FESS) in the 1970s, this technique has gained increasing popularity. Objective: To compare the efficacy of combined regional nasal anesthesia and general anesthesia -in a group of patients undergoing FESS versus the efficacy of general anesthesia. Patients and Methods: A double blinded study was carried out, in Al-Azhar University Hospitals on 40 adult patients undergoing endoscopic sinus surgery, Physical status (ASA I&II), after approval of the ethical committee of Al-Azhar University. Written consent was obtained from all patients. Every patient received an explanation to the purpose of the study and given a code number. The SPSS program was used for data handling. Results: After analysis of the data, the results have shown that the regional anesthesia in Group B could achieve better surgical fields, less blood loss, a stable hemodynamic profile with no need for the use of risky multimodal drugs, less anesthesia time, and better postoperative analgesia. Conclusion: Regional anesthesia of the nose after induction of general anesthesia in patients undergoing FESS is an effective method that can provide better surgical field visualization with fewer bleeding, more stable hemodynamic profile without the use of multimodal drugs, less anesthesia time, and better postoperative analgesia when compared to the induced hypotension technique.
