简要总结
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.
详细描述
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.
