Kids aren’t little adults. Pediatric sepsis and septic shock usually presents as ‘cold shock’ where as adult septic shock usually presents as ‘warm shock’, for example. In this episode, a continuation of our discussion on Fever from with Ottawa PEM experts, Sarah Reid and Gina Neto, we discuss the pearls and pitfalls in the recognition and management of pediatric sepsis and septic shock. We review the subtle clinical findings that will help you pick up septic shock before it’s too late as well as key maneuvers and algorithms to stabilize these patients. We cover tips for using IO in children, induction agents of choice, timing of intubation, ionotropes of choice, the indications for steroids in septic shock, and much more…..

Sepsis in children is a relatively rare emergency department presentation. Although only about 0.35% of pediatric emergency department visits are for sepsis, the mortality rate is as high as 2 to 10% (1,2). Having a sepsis guidelines protocol in the emergency department can decrease mortality from 5% to as low as 1% (2)
Red Flags in the Recognition of Pediatric Sepsis
Of the children <1yr, most will be
Unexplained tachycardia (after correcting for fever – see below)
Poor perfusion (long cap refill, lethargy, irritability)
Conditions that predispose to sepsis: neuromuscular disease, immunocompromised, respiratory conditions, cardiac disease
Temperature Corrected Heart Rate and Respiratory Rate
**Recall from podcast 48, rule of thumb – Heart Rate increases by approximately 10 beats/min and Respiratory Rate by 5 breaths/min for every Celsius degree (1.8 degree of Fahrenheit) of fever >38°C
Normal Pediatric Vital Signs
Heart Rate (beats/min)
Blood Pressure (mm Hg)
Respiratory Rate (breaths/min)
12 > yr
Hypotension is a Late Sign of Pediatric Septic Shock
Be very cautious in setting of tachycardia and DO NOT WAIT for hypotension to make diagnosis of septic shock.
A pediatric patient with hypotension and sepsis is a pre-arrest patient.
Investigations in Sepsis
Blood work should include CBC, electrolytes, glucose, kidney function, blood gas, blood cultures, LFTs, and lactate. Urine cultures are commonly done to identify a possible source. Clinical history guides imaging such as chest x-ray.
ABC – DEFG = ABC, DON’T EVER FORGET GLUCOSE
Up to 25% of children with septic shock will have adrenal insufficiency, so always check glucose in septic children. Extremes in blood glucose in sepsis are associated with higher mortality in children (2). Arterial lactate 2 times upper limit of normal indicates organ dysfunction.
Acute Management of Pediatric Sepsis
Fluid Resuscitation in Pediatric Sever Sepsis and Septic Shock
Circulation is of paramount importance in this patient and COMES BEFORE AIRWAY and all other concerns. Thus the approach should be CAB:
1) Circulation, 2) Airway, 3) Breathing.
Establishing IV access in a septic child can be very difficult, especially in the setting of hypotension. If, after 1MINUITE of trying, you cannot establish IV access, move to IO (ideally x2).
Initial fluid goal: 60cc/kg of NS in first hour (3)(2)
Older children: level 1 infuser
Blood pressure should not be a deciding factor in giving fluids. All septic patients should receive the initial boluses.
Intraosseous Access (IO)
IO access can be used in all ages, even in awake patients. Studies show that the pain from the IO comes more from the actual infusion than the insertion (5). In order to decrease pain, consider infiltrating lidocaine into the bone prior to infusion of fluids. The possibility of pain should not cause hesitation in establishing IO access. (2)
Sites (in this order of preference):
You can administer the same agents through an IO as an IV (fluids, antibiotics, vasopressors etc.)(2)
Initial Antibiotic Choice: Ceftriaxone 100mg/kg IV push(2)
When to intubate in Pediatric Sepsis and Septic Shock?
Consider early intubation in fluid refractory septic shock (after 3 boluses of 20ml/kg IV NS) or in any compromised airway.
Infants or neonates with severe sepsis may require early intubation. Intubation and mechanical ventilation increases intrathoracic pressure which reduce venous return and lead to worsening shock. Therefore, fluid resuscitation must be done first.
Choice of medications in intubation
There is no strong data supporting any particular induction agents or paralytic agents in the intubation of a septic child.
Drug of choice as it is relatively safe in hypotension and tachycardia. However, catecholamine depletion can cause refractory hypotension and result in worsening shock.
Should not be used for long-term sedation in children younger than 3 years old because of an association with fatal metabolic acidosis.
Should be discouraged or used carefully in septic shock as it inhibits the adrenal axis and sympathetic nervous system affecting hemodynamic stability. Etomidate is associated with increased mortality in children with meningococcal sepsis because of adrenal suppression effect.
Succinylcholine 1 mg/kg (or 2mg/kg in infants) IV or Rocuronium 0.45-0.6 mg/kg IV are both reasonable choices for paralytic agents.
Fluid Refractory Shock
If there are no signs of improvement within 1 hour of aggressive fluid resuscitation (remember goal of 60cc/kg), the initiation of ionotropes is indicated. Consider which agent you will use early (during second bolus of 20cc/kg) so that it can be ready to administer at 60min mark without delay if necessary. (2)
Cold vs. Warm shock
Most children have COLD shock, which is characterized by high SVR and low cardiac output (this differs from adults who usually have low SVR and present with warm shock). Thus, children are poorly perfused, have delayed cap refill with cold extremities and have a temperature differential between their core and their extremities. (5)
Ionotropic Choices in Pediatric Septic Shock
Cold Shock: Epinephrine 0.05-0.3 mcg/kg/min and titrate to effect
Warm Shock: Norepinephrine .05-0.3 mcg/kg/min and titrate to effect.
You can safely start these inonotropes through a peripheral IV or IO. The lack of a central line should not delay the initiation of inonotropes at the 60min mark. (2)(5)
Adjunct Treatments in the Management of Pediatric Sepsis and Septic Shock
Glucose: Remember to check the glucose in all children and treat as necessary. Both hypo and hyperglycemia are associated with worse outcomes. For glucose <6mmol, start D10W 5cc/kg (avoid higher concentration). (2)
Corticosteroids: The use of hydrocortisone in pediatric septic shock is currently being investigated and its role is unclear. Consider using hydrocortisone 2mg/kg in any child that has fluid and inotropic resistant septic shock or proven adrenal insufficiency (1).
Goals of Resuscitation in Pediatric Septic Shock
Normalization of vital signs is a main goal. Aim for a normal blood pressure, pulse (without differences between central and peripheral pulses).
Clinically, the child should have a normal capillary refill, warm extremities and urine output >1ml/kg/hour indicating improved perfusion. Lactate and mental status should be normalized as well.
Cognitive Decision Aids in The Management of Pediatric Sepsis and Septic Shock
ESTABLISHED PROTOCOLS for pediatric sepsis have been shown to DECREASE MORTALITY. (5)(2) It is helpful to have your room equipped with PALS algorithms (6), broslow tapes, GCS and normal vital sign tables to facilitate timely and accurate decisions. See below for The Children’s Hospital of Eastern Ontario pediatric sepsis algorithm.
Extra-Corporeal Membrane Oxygenation (ECMO)
If all else fails, ECMO can be used in the child who is in cardio-respiratory failure and refractory to all treatment. (2) However, in Canada, this treatment is almost exclusive to the ICU setting given all the resources involved.

Key Take Home Points
Hypotension is a late sign – do not wait for it to diagnose and aggressively treat pediatric sepsis.
CAB, not ABCs – fluid 20ml/kg is the first priority even if normal BP. Aim for three boluses over the first hour. Don’t delay using an IO!
Early goal directed therapy – early antibiotics! (ceftriaxone 20 100mg/kg IV)
Don’t forget glucose –a large proportion of septic children have adrenal insufficiency, which is associated with increased mortality.
Answer: A history of recent surgery, neuromuscular disease, respiratory or cardiac desease or immunocompromised state should all increase your suspicion for sepsis in a child presenting to the ED with fever. Infants under 1 month of age are especially high risk, and early adolescents are also at risk.
Answer: Hypotension is almost universal in adults, where as unexplained tachycardia without hypotension signifies septic shock in children. Hypotension is a late sign of septic shock in children. Whereas adults usually present in ‘warm shock’, children usually present in ‘cold shock’. Finally, the incidence of adrenal insufficiency in septic shock is much higher than in adults, and so hypoglycemia should be assessed and treated early in the management of children in septic shock, and consideration of steroid therapy should be given in fluid refractory shock.
Answer: In addition to signs of poor perfusion (prolonged capillary refill, lethargy and irritability), a sometimes overlooked clue to the presence of septic shock is tachycardia that is out of proportion to fever (HR increases by about 10bpm and RR by 5 breaths/min for every Celsius degree elevation of temperature above 38).
Answer: Aggressive fluid administration (60ml/kg NS) before attempts at intubation, unless a respiratory arrest is imminent. The priorities of management in septic shock is CAB (Circulation, Airway, Breathing) rather than ABC.
Answer: Ketamine, although not supported by any vigorous data, is usually the drug of choice as it is relatively safe in patients with hypotension. Propofol is associated with fatal metabolic acidosis in children.
Answer: The goals of resuscitation in pediatric septic shock are the normalization of vital signs, normal mental status, normal capillary refill, warm extremities, a urine output of >1ml/kg/hr and a normal lactate.
