What is the initial fluid resuscitation strategy for a neonate in shock and how should fluids be chosen?

• A. Begin isotonic crystalloid boluses (10 mL/kg) and reassess perfusion; if hypotension persists, start inotropes and monitor urine output.
• B. Begin hypotonic fluids to prevent edema.
• C. Give a single bolus and stop after response.
• D. Fluid resuscitation is not indicated in neonatal shock.

Answer: (D)

In neonatal shock, the first step is to restore intravascular volume with isotonic crystalloids and reassess perfusion after each intervention. Start with 10 mL/kg of an isotonic fluid (such as normal saline or a balanced crystalloid) and watch how perfusion improves—look at blood pressure, capillary refill, skin perfusion, urine output, and mental status. If perfusion remains poor or hypotension continues after that bolus, give additional boluses as needed and consider starting inotropic support if hypotension persists despite adequate fluid resuscitation. Monitor urine output closely, aiming for at least 1 mL/kg/hr as a sign of adequate kidney perfusion. Fluids should be isotonic to avoid cellular edema and electrolyte disturbances; hypotonic fluids are avoided because they can worsen edema and hyponatremia. This approach emphasizes prompt fluid resuscitation to restore perfusion, with escalation to inotropes when necessary, rather than withholding fluids.
