staff physician

In practice, staff physicians, residents, and nurses are grossly inaccurate at estimating blood loss after vaginal or cesarean delivery. There tends to be an underestimation which only gets worse with increasing blood loss [21]. Care providers should rely on the clinical picture of the patient to guide fluid and resuscitation management. Clinical signs of severe hemorrhagic shock include decreased urine output, altered mental status (confusion, anxiety, and lethargy), tachypnea, decreased pulse pressure and the late signs of tachycardia and hypotension [20].
