Electromyographic and histological features of postpartum hypernatremic rhabdomyolysis
A 20-year-old lady was admitted 2 weeks after first delivery with progressively declining word output for 10 days. She was disoriented for 3 days before admission with oliguria. She had normal tone and power with brisk tendon reflexes. EMG of right upper and lower limb muscles revealed fibrillations and positive sharp waves. Muscle power remained normal during hospital stay. Serum CK was 6,139 units/l at admission (normal range: 50-200. units/l); 4,175 units/l on the day of EMG and declined to 149 units/l at 1 month follow-up. Subsequently, she had uneventful second pregnancy and puerperium 1 year later.
