What is the initial management for pediatric patients presenting with shock?

From the Guidelines

The initial management of pediatric shock should prioritize rapid recognition and intervention with a focus on restoring adequate tissue perfusion, starting with securing the airway, ensuring adequate breathing, and establishing vascular access, followed by administering isotonic crystalloid fluid boluses of 20 mL/kg, as recommended by the most recent guidelines 1. The management of pediatric shock requires a comprehensive approach, including:

• Securing the airway, ensuring adequate breathing, and establishing vascular access through peripheral IV lines or intraosseous access if IV placement is difficult
• Administering isotonic crystalloid fluid boluses of 20 mL/kg (typically normal saline or Ringer's lactate) over 5-10 minutes, reassessing after each bolus and repeating up to 60 mL/kg if needed, as supported by the 2020 international consensus on cardiopulmonary resuscitation and emergency cardiovascular care science with treatment recommendations 1
• Simultaneously obtaining blood samples for laboratory studies, including complete blood count, electrolytes, blood gas, lactate, and cultures if infection is suspected
• Continuous cardiorespiratory monitoring to track vital signs and response to treatment
• For persistent shock despite fluid resuscitation, initiating vasopressors such as epinephrine (0.05-0.3 mcg/kg/min) for cold shock or norepinephrine (0.05-0.3 mcg/kg/min) for warm shock
• Treating the underlying cause, which may include antibiotics for septic shock (e.g., ceftriaxone 50-100 mg/kg IV), correction of hypoglycemia with D10W (2-4 mL/kg), or blood products for hemorrhagic shock, as outlined in the surviving sepsis campaign guidelines 1 and the 2010 American Heart Association guidelines for cardiopulmonary resuscitation and emergency cardiovascular care 1 Key considerations in the management of pediatric shock include:
• The importance of rapid recognition and intervention to prevent decompensation and cardiac arrest
• The need for individualized treatment based on the underlying cause of shock and the patient's response to initial therapy
• The role of fluid resuscitation, vasopressors, and other supportive therapies in restoring adequate tissue perfusion and preventing organ dysfunction
• The importance of continuous monitoring and reassessment to guide treatment and adjust therapy as needed, as emphasized in the 2020 international consensus on cardiopulmonary resuscitation and emergency cardiovascular care science with treatment recommendations 1

From the FDA Drug Label

Dopamine Hydrochloride in 5% Dextrose Injection, USP is indicated for the correction of hemodynamic imbalances present in shock due to myocardial infarction, trauma, endotoxic septicemia, open heart surgery, renal failure and chronic cardiac decompensation as in refractory congestive failure When indicated, restoration of circulatory volume should be instituted or completed with a suitable plasma expander or whole blood, prior to administration of dopamine hydrochloride. Begin infusion of dopamine hydrochloride solution at doses of 2 to 5 mcg/kg/min in adult or pediatric patients who are likely to respond to modest increments of heart force and renal perfusion

The initial management for pediatric patients presenting with shock involves restoration of circulatory volume with a suitable plasma expander or whole blood, followed by the administration of dopamine hydrochloride at a dose of 2 to 5 mcg/kg/min 2. It is essential to monitor the patient's response and adjust the dosage accordingly to achieve the desired hemodynamic or renal response 2. Key considerations include:

• Restoration of circulatory volume
• Administration of dopamine hydrochloride
• Monitoring of the patient's response
• Adjustment of dosage as needed The dosage of dopamine should be adjusted according to the patient's response, with consideration of factors such as urine flow, cardiac output, blood pressure, and distribution of peripheral perfusion 2.

From the Research

Initial Management of Pediatric Shock

The initial management of pediatric patients presenting with shock involves several key steps, including:

• Early recognition of shock through close attention to historical clues, physical examination, and vital sign abnormalities 3
• Rapid restoration of adequate cardiovascular function 4
• Eradication of the inciting invasive infection, including prompt administration of empiric broad-spectrum antimicrobial medications 4
• Supportive care of organ system dysfunction 4

Assessment and Monitoring

Careful and constant assessment of the child's systemic perfusion is crucial in managing pediatric shock 5. This includes:

• Monitoring of oxygenation and ventilation
• Maintenance of the child's heart rate, as pediatric cardiac output is often directly related to heart rate 5
• Regulation of total fluid intake and output

Treatment Goals

The goal of treatment of shock in pediatric patients is to ensure that cardiac output is adequate to provide tissue oxygenation and substrate delivery 5. This can be accomplished through:

• Careful titration of intravenous fluids to optimize ventricular preload
• Maximization of ventricular function, often with inotropic or vasodilator support 5

Fluid Resuscitation

The choice of fluid for resuscitation in pediatric shock is important. A study comparing bicarbonated Ringer's solution with lactated Ringer's solution found that the bicarbonated solution was associated with reduced complications and improved outcomes 6. The use of isotonic crystalloids, such as lactated Ringer's solution or normal saline, is also common in the initial management of pediatric shock 6.

Early Recognition and Intervention

Early recognition and treatment of shock in pediatric patients is critical to prevent or reverse organ dysfunction and improve morbidity and mortality 3, 7. This requires a thorough understanding of the pathophysiology and clinical progression of shock in children, as well as the rationale and potential complications of management 5, 7.
