Opioid-Free Anesthesia in FESS: A Prospective ERAS Study

1. Information for Patients and Families What is this study about? When patients undergo functional endoscopic sinus surgery (FESS), strong pain relievers called opioids are traditionally used during anesthesia. While effective, opioids can sometimes cause unwanted side effects such as nausea, vomiting, dizziness, or prolonged recovery times. This study investigates an "Opioid-Free Anesthesia" (OFA) approach combined with Enhanced Recovery After Surgery (ERAS) protocols. ERAS is a modern, science-based care pathway designed to help patients recover faster and more comfortably after surgery. Why is this study important? The goal of this study is to see if skipping opioids during sinus surgery-and using alternative pain-management techniques instead-leads to better perioperative outcomes. We want to find out if patients experience less pain, fewer side effects (like nausea), and a quicker, safer return to their daily routines. What will happen if you participate? If you fit the criteria and agree to join, your surgical journey will follow the standard ERAS protocol, but your anesthesia will be managed without conventional opioid medications. Researchers will closely monitor your comfort, pain levels, and recovery speed before, during, and after your sinus surgery. 2. Technical Summary for Health Care Providers Official Study Title: Opioid-Free Anesthesia in Functional Endoscopic Sinus Surgery: Effects on Perioperative Outcomes - A Prospective Observational ERAS Study Study Rationale and Objective: Traditional opioid-based anesthesia is often associated with opioid-induced side effects (OIAEs) such as postoperative nausea and vomiting (PONV), respiratory depression, and delayed discharge. This prospective observational study aims to evaluate the clinical impact of Opioid-Free Anesthesia (OFA) embedded within an Enhanced Recovery After Surgery (ERAS) pathway for patients undergoing elective Functional Endoscopic Sinus Surgery (FESS). The primary focus is to assess whether an OFA-ERAS strategy optimizes perioperative outcomes, stabilizes intraoperative hemodynamics, and minimizes recovery times compared to historical opioid-based standards. Study Design: Prospective, Observational Study. Estimated Enrollment: 104 patients. Setting: Perioperative tracking following strict institutional ERAS principles.

Nasal Dexmedetomidine Versus Systemic Infusion Dexmedetomidine in Reducing Intraoperative Opioid Consumption in Nasal Endoscopic Surgeries

Background: Optimizing intraoperative hemodynamics and minimizing opioid use are crucial in nasal endoscopic surgeries. Objective: To compare the efficacy of intranasal dexmedetomidine spray and intravenous dexmedetomidine infusion in reducing intraoperative opioid requirements and improving perioperative outcomes. Methods: A prospective randomized controlled study was conducted on 50 patients undergoing nasal endoscopic surgeries. Patients will be randomized into two groups: Group A received IV dexmedetomidine infusion; Group B received intranasal dexmedetomidine. Intraoperative fentanyl use, postoperative morphine consumption, hemodynamic parameters, and pain scores will be evaluated. Measurements: All the following data will be collected: * Demographic data: age, sex, weight, height, BMI, ASA class, indication and duration of surgery. * Hemodynamic Parameters: HR, BP, SpO2, and MAP will be recorded preoperative, and every 10 min till the end of surgery. * Quality of surgical field through endoscopic surgical field grading system Primary outcome is Reducing opioid consumption intraoperatively to give the best surgical field control and hemodynamic control. Secondary outcomes are pain score postoperative, postoperative analgesics, and surgical field satisfaction. Statistical analysis Statistical analysis will be done by SPSS v26 (IBM Inc., Chicago, IL, USA). Shapiro-Wilks test and histograms will be used to evaluate the normality of the distribution of data. Quantitative parametric variables will be presented as mean and standard deviation (SD) and compare between the two groups utilizing unpaired Student's T- test. Quantitative non-parametric data will be presented as median and interquartile range (IQR) and will be analyzed by Mann Whitney-test. Qualitative variables will be presented as frequency and percentage (%) and will be analyzed utilizing the Chi-square test or Fisher's exact test when appropriate. A two tailed P value \< 0.05 is considered statistically significant.

Endoscopic Direct "Draf IIa" (Carolyn's Window Approach) Versus Endoscopic Angled "Draf IIa"Approach in Chronic Rhinosinusitis With Frontal Sinus Affection ( A Comparative Study ).

Patients with chronic rhinosinusitis with frontal sinus affection indicated for sinuscopy will be randomly categorized in 2 groups: group A will have endoscopic directDraf IIa frontal sinusotomy and group B will have endoscopic angled Draf IIa frontal sinusotomy, the two groups will be compared according to ostium patency and perioperative morbidity
