What supportive medications should be administered in addition to antibiotics for this patient?

Supportive Medications for Sepsis/Severe Infection

In addition to antibiotics, administer aggressive fluid resuscitation with isotonic crystalloids (20 mL/kg boluses), followed by vasopressors/inotropes (starting with dopamine or epinephrine for cold shock, norepinephrine for warm shock), oxygen support, correction of metabolic derangements (hypoglycemia, hypocalcemia), and hydrocortisone for catecholamine-resistant shock in patients at risk for adrenal insufficiency 1.

Initial Resuscitation (First 5-15 minutes)

Respiratory Support

• Start with face mask oxygen, escalating to high-flow nasal cannula or nasopharyngeal CPAP for respiratory distress and hypoxemia 1
• Delay intubation until after cardiovascular resuscitation when possible to minimize hemodynamic instability 1

Vascular Access & Fluid Resuscitation

• Use peripheral IV or intraosseous access if central access unavailable 1
• Push 20 mL/kg boluses of isotonic crystalloids or albumin over 5-10 minutes, titrating to clinical endpoints:
  • Capillary refill <2 seconds
  • Normal blood pressure for age
  • Warm extremities
  • Urine output >1 mL/kg/hr
  • Normal mental status 1
• Stop fluid boluses immediately if hepatomegaly or rales develop—switch to inotropes instead 1

Metabolic Corrections

• Correct hypoglycemia and hypocalcemia during initial resuscitation 1
• These are critical immediate interventions that directly impact cardiovascular function

Hemodynamic Support (15-60 minutes)

For Fluid-Refractory Shock

Begin inotropes/vasopressors based on shock phenotype 1:

• Cold shock (normal BP): Titrate dopamine centrally, or epinephrine if dopamine-resistant 1
• Cold shock (low BP): Titrate fluid and epinephrine; target ScvO₂ >70% and hemoglobin >10 g/dL 1
• Warm shock (low BP): Titrate fluid and norepinephrine; target ScvO₂ >70% 1

Additional Vasodilator Therapy

• For low cardiac output with elevated systemic vascular resistance and normal blood pressure: add vasodilators (nitrosovasodilators, milrinone) with volume loading 1

Catecholamine-Resistant Shock (After 60 minutes)

Hydrocortisone

• Administer hydrocortisone if patient is at risk for absolute adrenal insufficiency 1
• This includes patients on chronic corticosteroids who need stress dosing 2

Rule Out Reversible Causes

• Evaluate and reverse: pneumothorax, pericardial tamponade, endocrine emergencies (hypoadrenalism, hypothyroidism), intra-abdominal hypertension >12 mmHg 1

Blood Product Support

• Transfuse to hemoglobin >10 g/dL during acute resuscitation of shock and hypoxemia 1
• After recovery from shock, target can be lowered to <7.0 g/dL 1
• Platelet transfusion using similar targets as adults 1
• Plasma therapies for sepsis-induced thrombotic disorders (DIC, secondary thrombotic microangiopathy, TTP) 1

Glycemic Control

• Target glucose <180 mg/dL 1
• Always accompany insulin with glucose infusion in newborns and children—some are insulin-deficient while others are insulin-resistant 1

Sedation & Analgesia

• Use sedation with defined goals in mechanically ventilated patients 1
• Monitor drug toxicity labs closely—drug metabolism is reduced during severe sepsis, increasing risk of adverse events 1

Fluid Management After Shock Resolution

• Use diuretics to reverse fluid overload once shock resolves 1
• If diuretics fail, initiate continuous venovenous hemofiltration (CVVH) or intermittent dialysis to prevent >10% total body weight fluid overload 1

Nutrition

• Provide enteral nutrition to children who can be fed enterally 1
• Parenteral feeding for those who cannot tolerate enteral feeds 1

Medications to Avoid or Adjust

• NSAIDs are almost always contraindicated in severe infections 2
• Diuretics and RAAS inhibitors should usually be interrupted during acute illness 2
• Continue beta-blockers and statins in most cases 2
• Paracetamol can be prescribed as needed 2

Common Pitfalls

• Do not continue fluid boluses if hepatomegaly or rales develop—this indicates fluid overload requiring inotropic support, not more fluids 1
• Do not delay antibiotics for blood cultures—obtain cultures when possible but never delay antibiotic administration beyond 1 hour of sepsis identification 1
• Do not forget stress-dose corticosteroids in patients with chronic steroid use or suspected adrenal insufficiency 1, 2
