Official title
Evaluation of Ultrasound-Guided Auricularis Magnus Nerve Block for Postoperative Pain Control in Ear Surgery
Overview
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.
Detailed description
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.
Interventions
- Procedure Auricularis Magnus Nerve Block
Auricularis Magnus Nerve block will be performed using 5 mL of %0.5 bupivacaine - Procedure Control Group
Intravenous analgesics 1 gram paracetamol, 20 mg tenoxicam, 8 mg ondansetron will be administered.
Primary outcome measures
- Opioid consumption [Time frame: During the operation]
Secondary outcome measures (2)
- Morphine consumption [Time frame: 1 hours after surgery(T1), 6 hours after surgery (T2), 12 hours after surgery (T3), 24 hours after surgery (T4)]
- NRS Scores [Time frame: 1 hours after surgery(T1), 6 hours after surgery (T2), 12 hours after surgery (T3), 24 hours after surgery (T4)]
