Role of clonidine premedication as a part of hypotensive anaesthesia during functional endoscopic sinus surgery: A placebo-controlled study

The advent of functional endoscopic sinus surgery (FESS) has revolutionized the treatment of chronic sinusitis over the last decade. Although it has been well-established that FESS is more efficacious than conventional surgery, the lack of a quantifiable means of assessing results remains one of the major shortcomings of the technique, and hence a source of criticism. Since the pathophysiology of chronic sinusitis is intimately related to the mucociliary mechanism of the nose and sinuses, it seems logical to use this parameter as a yardstick of success. We undertook a prospective, controlled study of 40 patients and measured their “saccharin times” before and after surgery. The results show a marked reduction in clearance times postoperatively, corresponding well with improvement in symptom profile. We therefore propose this technique as a simple, safe and reliable method of assessing the results of surgery. Furthermore, the method could act as a preoperative indicator of ciliary motility disorders, as the prognosis in these patients is distinctly poor.

Background: Functional endoscopic sinus surgery (FESS), effective control of bleeding is essential to maintain a clear operative field and to minimize complications. Intraoperative bleeding is one of the major problems in endoscopic surgery of sinuses. Controlled hypotension is a technique used to limit intraoperative blood loss to provide the best possible field for surgery. Objective: The objective of study was role of Hypotensive Anaesthesia in Functional Endoscopic Sinus Surgery and designed to compare intraoperative hemorrhage and the visibility of the operative field during normotension and hypotension anesthesia. Methods: Prospective randomized study includes a total of 60 ASA I-II patients who underwent elective FESS surgery. Patients randomly assigned in two groups the hypotension group (Group A) and the normotension group (Group B). Intraoperative mean arterial pressure (MAP), heart rate (HR) were recorded. Results : This study shows the mean ages of the patients of group A group B were 33.36±7.61 and 32.46±7.73 years respectively. No statistically significant difference was observed among groups at 0.05 level in term of age. The mean heart rate pre-anaesthesia and preoperative among the patients of different groups in different follows up period. Significance differences were observed among groups in term of heart rate at 5 minute, 15 minute, 30 minute, 45 minute and 60 minute. The mean arterial mean blood pressure before pre-anaesthesia and preoperative estimation among the patients of different groups in different follows up period. Significance differences were observed among groups at 5 minute, 15 minute, 30 minute, 45 minute and 60 minute. Conclusion: This study demonstrated that Controlled hypotension can be achieved equally and effectively by nitroglycerin and labetalol reduced significantly intraoperative hemorrhage and produce hypotensive anesthesia. Both are equally effective in providing ideal surgical field during functional endoscopic sinus surgery (FESS). Bangladesh J Otorhinolaryngol; April 2018; 24(1): 8-13
