Study of prognostic factors associated with outcome in pediatric severe sepsis: What is the role of steroids?*.

6,693 pediatric patients were identified at 27 hospitals.

Conclusions: No evidence that steroids are associated with improved outcome in critically ill infants and children with sepsis. Although steroids may be given preferentially to more severely ill children,their use was associated with increased mortality (Odd ratio 1.9, 95%CI 1.7-2.2).

SSC, an initiative of the European Society of Intensive Care Medicine, the International Sepsis Forum, and the Society of Critical Care Medicine, has been developed to improve the management, diagnosis, and treatment of sepsis

The SSC aims to reduce mortality from sepsis via a multi-point strategy, primarily: ◦ Building awareness of sepsis ◦ Improving diagnosis ◦ Increasing the use of appropriate treatment ◦ Educating healthcare professionals ◦ Improving post-ICU care ◦ Developing guidelines of care ◦ Facilitating data collection for the purposes of audit

and feedback

CORTICOSTEROIDS

Quality improvement initiatives (Adults):Sepsis resuscitation bundleSepsis management bundle

The goal is to perform all indicated tasks 100% of the time within the first 6 hours of identification of severe sepsis.

The tasks are:1. Measure serum lactate2. Obtain blood cultures prior to antibiotic administration3. Administer broad-spectrum antibiotic, within 3 hrs of ED

admission and within 1 hour of non-ED admission

4. In the event of hypotension and/or a serum lactate > 4 mmol/La. Deliver an initial minimum of 20 ml/kg of crystalloid or an equivalentb. Apply vasopressors for hypotension not responding to initial fluid resuscitation to maintain mean arterial pressure (MAP) > 65 mm Hg

5. In the event of persistent hypotension despite fluid resuscitation (septic shock) and/or lactate > 4 mmol/La. Achieve a central venous pressure (CVP) of ≥ 8 mm Hgb. Achieve a central venous oxygen saturation (ScvO2) ≥70 % or mixed venous oxygen saturation (SvO2) ≥ 65 %

Efforts to accomplish these goals should begin immediately, but these items may be completed within 24hours of presentation for patients with severe sepsis or septic shock.1. Administer low-dose steroids for septic shock in accordance with a standardized ICU policy.

If not administered, document why the patient did not qualify for low-dose steroids based upon the standardized protocol.

2. Administer drotrecogin alfa (activated) in accordance with a standardized ICU policy.

If not administered, document why the patient did not qualify for drotrecogin alfa (activated).3. Maintain glucose control ≥ 70, but < 150 mg/dl4. Maintain a median inspiratory plateau pressure (IPP)* < 30 cm H2O for mechanically ventilated patients

Antibiotics◦ “We recommend” within 1 hrMechanical ventilation◦ No graded recommendationFluid resuscitation◦ “We suggest” boluses of 20 mL/kg over 5–10 mins, titrate to

clinical monitors

Vasopressors/ inotropes◦ “We suggest” dopamine as the first choice of support for the

pediatric patient with hypotension refractory to fluid resuscitation.

Therapeutic end points◦ “We suggest” that the therapeutic end points of resuscitation

of septic shock be normalization of the heart rate, capillary refill of 2 secs, normal pulses with no differential between peripheral and central pulses, warm extremities, urine output 1 mL·kg1·hr1, and normal mental status

Approach to pediatric septic shock◦ See diagramSteroids◦ “We suggest” that hydrocortisone therapy be reserved for use

in children with catecholamine resistance and suspected or proven adrenal insufficiency

Protein C and activated protein C◦ “We recommend” against the use rhAPC in children

DVT prophylaxis◦ “We suggest” the use of DVT prophylaxis postpubertal

children with severe sepsisStress ulcer prophylaxis◦ No graded recommendationsRenal replacement therapy◦ No graded recommendationsGlycemic control◦ No graded recommendations

Sedation/ analgesia◦ “We recommend” sedation protocols with a sedation goal when

sedation of critically ill mechanically ventilated patients with sepsis is required.

Blood products◦ No graded recommendationsIVIG◦ “We suggest” that immunoglobulin be considered in children with

severe sepsisECMO◦ “We suggest” that use of ECMO be limited to refractory

pediatric septic shock and/or respiratory failure that cannot be supported by conventional therapies
