Post Operative PainNCT06869967
Evaluation of Postoperative Pain Control in Ear Surgery
A study testing Auricularis Magnus Nerve Block in people with Post Operative Pain and Analgesia, run by Kocaeli University at 1 site in Turkey (Türkiye).
Trial summary
Middle ear surgery is the most popular procedure in ear, nose and throat surgery. Increased sympathetic stimulation after surgery can activate the sympathetic system, causing hypertension and increased heart rate. Read more about this study

About this study
Official title: Evaluation of Ultrasound-Guided Auricularis Magnus Nerve Block for Postoperative Pain Control in Ear Surgery
Middle ear surgery is the most popular procedure in ear, nose and throat surgery. Increased sympathetic stimulation after surgery can activate the sympathetic system, causing hypertension and increased heart rate. As a result of these clinical conditions, hemorrhage can occur, which can impair the quality of the surgical field, which is undesirable in middle ear surgery.Clinical studies should be conducted with auricularis magnus nerve block applied in the perioperative period in middle ear surgery and postoperative pain scores.

Middle ear surgery is the most popular procedure in ear, nose and throat surgery. Increased sympathetic stimulation after surgery can activate the sympathetic system, causing hypertension and increased heart rate. As a result of these clinical conditions, hemorrhage can occur, which can impair the quality of the surgical field, which is undesirable in middle ear surgery.Ultrasound-guided auricularis magnus nerve block can be used as a potential solution to these problems. Ultrasound-guided peripheral nerve block can be visualized. It is appropriate and applicable to block a single distal nerve with a small dose of local anesthetic under ultrasound guidance. Ultrasound-guided blocking of the blocked area has reduced side effects with increased accuracy and accurate analgesic effect.
In middle ear microsurgery, the nerve innervation of the postauricular incision area may not primarily originate from the auricularis magnus. Therefore, clinical studies should be conducted with auricularis magnus nerve block applied in the perioperative period in middle ear surgery and postoperative pain scores.

Control GroupProcedure or surgery
Intravenous analgesics 1 gram paracetamol, 20 mg tenoxicam, 8 mg ondansetron will be administered.
| Study group | Role | What they receive |
|---|---|---|
| Auricularis Magnus Nerve Block | Active comparator | Ultrasound (US) -guided Auricularis Magnus Nerve Block with 5 ml 0.5 % bupivacaine will performe preoperatively to all patients in the AMG group. Receives: Procedure: Auricularis Magnus Nerve Block |
| Control | Active comparator | In the control group, patients will be administered intravenous analgesics of 1 gram paracetamol, 20 mg tenoxicam, and 8 mg ondansetron 30 minutes before the end of the operation, as stated in the patient protocol, during their follow-up after general anesthesia. Receives: Procedure: Control Group |
