Fluid Resuscitation in the Emergency Room

Initial Fluid Selection and Administration

The American College of Emergency Physicians recommends crystalloids as the first-line fluid of choice for initial resuscitation in the ER, with balanced crystalloids like Lactated Ringer's generally preferred over normal saline to reduce the risk of hyperchloremic metabolic acidosis 1, 3
For septic patients, administer at least 30 mL/kg of crystalloid within the first 3 hours, as recommended by the Surviving Sepsis Campaign 2, 4
For non-septic patients requiring fluid resuscitation, use a fluid challenge technique with boluses of 250-1000 mL administered rapidly and repeatedly, as suggested by the European Society of Intensive Care Medicine 1, 5

The American Society of Anesthesiologists recommends specifying the fluid type, total volume to be administered, and rate of administration in fluid orders 3, 6
Include instructions for reassessment after each bolus and parameters for when to stop fluid administration, as recommended by the Society of Critical Care Medicine 1, 2, 5

Reassess the patient's hemodynamic status after initial fluid bolus, including clinical examination and evaluation of heart rate, blood pressure, respiratory rate, skin perfusion, capillary refill time, urine output, and mental status, as recommended by the American College of Emergency Physicians 1, 2, 5, 7
Target urine output of > 0.5 mL/kg/hr and consider serum lactate levels if available, aiming for a 20% reduction if elevated, as suggested by the Surviving Sepsis Campaign 1, 4, 5

Stop fluid administration when no improvement in tissue perfusion occurs, signs of fluid overload develop, or hemodynamic parameters stabilize, as recommended by the European Society of Intensive Care Medicine 1, 5, 7

For elderly patients or those with cardiac dysfunction, consider smaller boluses of 250-500 mL administered over 15-30 minutes with more frequent reassessment, as suggested by the American Geriatrics Society 1, 6
Consider earlier initiation of vasopressors if the patient remains hypotensive despite initial fluid resuscitation, as recommended by the Society of Critical Care Medicine 1, 8
