Initial Fluid Management for Pediatric Femur Fractures

Initial Assessment and Fluid Management

Pre-operative fluid therapy should be prescribed routinely for pediatric patients with femur fractures as many become hypovolaemic before surgery, according to the American Society of Anesthesiologists 1, 2
Cardiac output-guided fluid administration appears to reduce hospital stay and improve outcomes in patients with femur fractures, as recommended by the American College of Surgeons 1, 2

Initial fluid resuscitation should follow standard pediatric protocols with isotonic crystalloid solutions, as suggested by the American Academy of Pediatrics 1, 2
For a child (approximately 30-35kg), maintenance fluid requirements can be calculated using the 4-2-1 rule:
- 4 mL/kg/hr for the first 10 kg
- 2 mL/kg/hr for the next 10 kg
- 1 mL/kg/hr for each kg above 20 kg, totaling approximately 70-75 mL/hr, according to the Society of Critical Care Medicine 1, 3
Additional fluid boluses may be required if signs of hypovolemia are present, as stated by the American Heart Association 1, 2

Regular monitoring of vital signs including heart rate, blood pressure, capillary refill time, and urine output is essential to guide fluid management, as recommended by the American Society of Anesthesiologists 1, 2
In patients with femur fractures, hypovolemia is common and should be addressed promptly, according to the Orthopaedic Trauma Association 3
For complex cases or patients with significant comorbidities, consider more advanced monitoring such as invasive blood pressure monitoring, central venous pressure monitoring, and cardiac output monitoring, as suggested by the Society of Critical Care Medicine 4

During surgery, fluid management should be optimized to prevent hypovolemia, particularly at the time of cementation if applicable, as recommended by the American Society of Regional Anesthesia and Pain Medicine 1, 2
Avoiding intravascular volume depletion is crucial to reduce the risk of complications such as bone cement implantation syndrome, according to the American Academy of Orthopaedic Surgeons 1, 3

Early oral fluid intake should be encouraged postoperatively rather than routine prescription of intravenous fluids, as suggested by the Enhanced Recovery After Surgery Society 3
Continued monitoring of fluid balance is important in the postoperative period to detect and address hypovolemia, according to the American Society of Anesthesiologists 3
