Аннотация
RATIONALE: Ultrasound-guided brachial plexus block is a common anesthetic procedure used in upper extremity surgery. However, it may not be a suitable option for some patients.
PATIENT CONCERNS: A 17-year-old woman with the left palmar schwannoma scheduled for surgical treatment received ultrasound-guided brachial plexus block. The anesthesia modalities of the disease were discussed.
DIAGNOSES: Based on the patient's complaints and clinical appearance, provisional diagnosis of neurofibroma was considered.
INTERVENTIONS: In this case, we present a case of ultrasound-guided axillary brachial plexus block used for upper extremity surgery in this patient. It was not easily and painlessly reduced in the surgery, although the visual analogue scale score was 0 and no motor movements of the left arm and palm were observed. The pain was relieved by intravenous injection of 50 mcg remifentanil.
OUTCOMES: Immunohistochemically labeled pathological examination confirmed the mass to be a schwannoma. There was no need to apply additional analgesia after surgery, although the patient felt numbness in the left thumb for 3 days follow up.
LESSONS: Even if there is painless when skin-cutting after implementation of brachial plexus block, the patient is painful when pulls the nerve around the tumor during excision. It is necessary to give an analgesic drug or anesthetize a single terminal nerve as a supplement for brachial plexus block in patients with schwannoma.
