Opioid-Free Anesthesia in FESS with ERAS
This study tries a opioid-free anesthesia approach during functional endoscopic sinus surgery to see if pain, nausea, and recovery are improved for adults undergoing this procedure.
-
Opioid-free versus opioid-based anesthesia for adolescent idiopathic scoliosis
This test uses dexmedetomidine instead of intraoperative opioids to see if adolescents having scoliosis surgery have better pain control and fewer complications.
-
How opioid-free, opioid-sparing, and opioid-based anesthesia affect immune markers and cancer cell behavior after colorectal cancer surgery
This trial will test whether opioid-free or opioid-sparing anesthesia versus standard opioid-based anesthesia changes immune markers and affects cancer cell behavior in adults having elective colorectal cancer surgery.
-
Evaluating anesthesia techniques for reducing inflammation in bariatric surgery
This study tests different anesthesia methods during bariatric surgery to see which one helps reduce inflammation and supports better recovery for patients.
-
Opioid-Free Anesthesia to Improve Early Recovery After Thyroid Surgery
This study tests an opioid-free anesthesia plan against a traditional approach to see if it improves early recovery after thyroidectomy for adults.
