Appropriate oral fluid and electrolyte replacement is the initial treatment regimen for patients with mild to moderate emesis to avoid hyperemesis gravidarum defined as dehydration, electrolyte unbalance and ketosis. A newer oral rehydration solution OS-1 therapy may be safe and feasible in the mild to moderate emesis gravidarum population. Physicians are encouraged to use this practice to maintain the amount of water in the body and electrolytes and to improve the patient’s comfort.展开更多
