INTERVENTIONAL
Summary
This study is designed to evaluate the effectiveness of ultrasound-guided greater auricular nerve block (GAN) on the reduction of emergence agitation (EA) occurrence and EA severity in children who are receiving general anesthesia for a microscopic middle ear operation.
Eligibility
Inclusion Criteria5
- Age between 5 and 14 years (preschool to early school age group at highest risk for EA).
- ASA physical status I or II.
- Scheduled for elective microscopic middle ear surgery under general anesthesia (e.g., tympanoplasty, myringoplasty).
- Ability to comply with FLACC and PAED scoring during postoperative period.
- Informed consent obtained from a parent or legal guardian.
Exclusion Criteria6
- Known neurological, developmental, or psychiatric disorders (e.g., autism, ADHD, seizure disorder).
- Known hypersensitivity to amide local anesthetics (e.g., lidocaine, bupivacaine).
- Skin infection, hematoma, or trauma at or near the proposed block site.
- Non-elective (emergency) or combined surgeries.
- Inability to assess pain or agitation due to hearing loss, or communication impairment.
- Parental or legal guardian refusal to participate.
