Brachial Plexus Injury after Deep Sleep

깊은 수면 이후 발생한 상완신경총 손상

Lying on the side while falling asleep deeply after drinking or taking a sleeping pill can cause compressive neuropathy. We report a 70-year-old male patient of medial cord of left brachial plexus injury (BPI) after deep sleep. The mechanism of the injury might be compression and stretching of brachial plexus. The electrodiagnostic study was performed and the medial cord lesion of BPI was suggested. The ultrasonography image of compression site revealed the nerve swelling of medial cord of brachial plexus and median nerve at the mid-arm level. Pharmacologic treatment including oral prednisolone and exercise training were prescribed. On 6 months after initial visit, neurologic symptom and pain were improved but mild sequelae was remained.
