[Bilateral parotid gland swelling with hyperamylasemia following cesarean section under regional anesthesia--report of two cases].

Bilateral parotid gland swelling with hyperamylasemia occurred in two patients on the first postoperative day after cesarean section under combined epidural-spinal anesthesia. Total ephedrine doses used to treat hypotension due to anesthesia were 48 and 52 mg, respectively. These symptoms and findings seemed to have been caused by beta stimulating effect of high dose ephedrine.
