Initial resuscitation involves establishing large-bore IV access and administration of normal saline. Besides ordering routine laboratory studies (eg, complete blood cell (CBC) count, electrolyte levels, and coagulation studies), blood should be typed and cross-matched. The patient's blood loss and hemodynamic status should be ascertained, and in cases of severe bleeding, the patient may require invasive hemodynamic monitoring to direct therapy.
