Abstract:
We report medullary injury during adenoidectomy in two children who received injections of local anesthetic agents into the operative bed. Initial manifestations included hemiparesis, nystagmus, and ataxia. Magnetic resonance imaging showed hemorrhagic, paramedian medullary lesions in both patients. The mechanism of injury is likely to be injection of fluid into the medulla.
Insights
Local anesthetic injections during adenoidectomy can cause medullary injury in children. This rare complication may lead to neurological deficits such as hemiparesis and ataxia.
Area of Science:
- Neurology
- Pediatric Surgery
- Anesthesiology
Background:
- Adenoidectomy is a common pediatric surgical procedure.
- Local anesthetics are frequently used to manage pain during and after surgery.
Observation:
- Two children developed neurological symptoms including hemiparesis, nystagmus, and ataxia post-adenoidectomy.
- These symptoms were associated with injections of local anesthetic agents into the operative bed.
Findings:
- Magnetic resonance imaging revealed hemorrhagic, paramedian medullary lesions in both affected children.
- The likely mechanism of injury is direct injection of anesthetic fluid into the brainstem's medulla.
Implications:
- This case report highlights a potential, albeit rare, complication of adenoidectomy.
- Awareness of this risk is crucial for surgeons and anesthesiologists to ensure patient safety and optimize anesthetic techniques.
