Study of Ultrasound-Guided Bilateral Maxillary Nerve Block to Reduce Pain Medicine Use During Septorhinoplasty Surgery

What this Trial Is About

Researchers are evaluating the effect of a bilateral maxillary nerve block on pain management and remifentanil use during septorhinoplasty, a nasal surgery that often involves bone cutting and can cause significant bleeding and pain. The study includes 90 patients undergoing elective septorhinoplasty, aiming to compare the amount of remifentanil used during surgery between those receiving the nerve block and those who do not. The goal is to improve pain control and maintain stable blood pressure throughout the operation. Before surgery, patients in one group will receive an ultrasound-guided bilateral maxillary nerve block via the pterygopalatine fossa, in addition to general anesthesia, while the other group will have general anesthesia only. Anesthesia includes drugs like fentanyl, propofol, and rocuronium for induction, with maintenance by sevoflurane and remifentanil infusion adjusted according to blood pressure. Multimodal pain relief with intravenous dexketoprofen and paracetamol will be given around the time of surgery completion. Various intraoperative factors like remifentanil and sevoflurane use, bleeding, surgery duration, and extubation time will be recorded. Participants will be closely monitored before, during, and after surgery. Pain will be assessed using a Numeric Rating Scale at multiple time points up to one month after surgery. The Quality of Recovery-15 questionnaire will be completed before surgery, 24 hours after, and at one month. Satisfaction levels of patients, anesthesiologists, and surgeons will also be measured. The study focuses on understanding whether the nerve block can reduce opioid use and improve postoperative recovery and comfort.
