Severe Sepsis - Previously Healthy Infant or Child

Patient Population: Pediatric

These guidelines are intended for patients who meet criteria for severe sepsis:

         Probable or documented infection AND 

Systemic inflammatory response criteria AND 

Specific evidence of hypo-perfusion or organ dysfunction not explained by an alternative process: 

Cardiovascular dysfunction, OR 

Acute respiratory distress syndrome, OR 

Dysfunction in two or more other organ systems

Refer to consensus definitions for additional detail   

These guidelines are not intended for "rule out" scenarios in clinically stable patients; patients presenting with signs and/or symptoms of infection but not meeting criteria for severe sepsis should either be monitored without antibiotic therapy in appropriate circumstances or receive empiric antibiotics selected based on the suspected source and risk factors.  

Condition Major Pathogens  First Choice Therapy Alternative Therapy Comments

Severe sepsis, 0-28 days old, community-onset, previously healthy (admitted from home)   

See BCH SF Guidelines for Sepsis in the ICN for empiric therapy in neonates who develop severe sepsis while hospitalized  

Enteric gram-negative bacteria  

Group B streptococcus 

Less Common: 

Staphylococcus aureus 

Listeria monocytogenes 

Herpes simplex virus 

Ceftazidime 

AND 

Ampicillin 

REPLACE Ampicillin with Vancomycin if suspected skin, soft tissue, bone or joint source 

ADD Acyclovir pending HSV evaluation if not already completed 

For continuation of therapy if indicated after initial stabilization in appropriate circumstances, Ceftriaxone may be used in place of Ceftazidime if neonate meets specific safe use criteria 

ID consult recommended 

Evaluation for meningitis via LP is recommended as soon as able 

Refer to Neonatal Dosing Guideline for antibiotic doses and intervals

Refer to Fever Without a Source section if patient does not meet criteria for severe sepsis 

Antibiotic therapy should be re-evaluated at <= 48 hours and narrowed to target the identified source/pathogen. If a specific source or pathogen is not identified it is still recommended to narrow therapy in most circumstances.  

If Vancomycin was initiated, it should be discontinued at this time unless a resistant gram-positive pathogen is identified OR there is a clinically documented source of infection with higher likelihood of resistant gram-positive etiology. 

Severe sepsis, > 28 days old, community-onset, no preexisting comorbidities or recent healthcare exposure 

Staphylococcus aureus 

Streptococcus pneumoniae 

Group A streptococcus 

Neisseria meningitidis 

Enteric gram-negative bacteria 

Ceftriaxone
50 mg/kg/dose (max 2000 mg/dose) IV q24h  

(dosing for non-CNS infection; refer to Meningitis section if meningitis is suspected)  

AND 

Vancomycin  

(follow link for dosing & monitoring)   

Consult a clinical pharmacist for patient-specific Vancomycin recommendations if there is evolving kidney injury 

ADD Metronidazole
10 mg/kg/dose (max 500 mg/dose) IV q8h for suspected intra-abdominal infection 

Penicillin or cephalosporin allergy with higher risk for allergic reaction

Aztreonam
30 mg/kg/dose (max 2000 mg/dose) IV q8h in place of Ceftriaxone (use with Vancomycin) 

  

ID consult recommended 

Antibiotic therapy should be re-evaluated at <= 48 hours and narrowed to target the identified source/pathogen 

If Vancomycin was initiated, it should be discontinued at this time unless a resistant gram-positive pathogen is identified OR there is a clinically documented source of infection with higher likelihood of resistant gram-positive etiology.   

Pediatric Empiric Antimicrobial Therapy Guidelines

This is a subsection of the UCSF Benioff Children’s Hospitals Empiric Antimicrobial Therapy Guidelines, developed by the Pediatric Antimicrobial Stewardship Programs at each campus to inform initial selection of empiric antimicrobial therapy for children at the UCSF Benioff Children’s Hospitals and affiliated outpatient sites. 

These are guidelines only and not intended to replace clinical judgment. Modification of therapy may be indicated based on patient comorbidities, previous antibiotic therapy or infection history. Doses provided are usual doses but may require modification based on patient age or comorbid conditions. Refer to Pediatric Antimicrobial Dosing Guideline for further guidance on dosing in children, and Neonatal Dosing Guideline for infants < 1 month of age. Consult a pediatric pharmacist for individualized renal or hepatic dose adjustment. Durations provided are usual recommendations for patients who are responding appropriately to therapy. For additional guidance, please contact Pediatric Infectious Diseases (ID) or the Pediatric Antimicrobial Stewardship Program (ASP) at the campus where your patient is receiving care.  

For questions or feedback about these guidelines, please email primary content owners, Rachel Wattier, Pediatric ASP Medical Director at BCH SF and Prachi Singh, Pediatric ASP Medical Director at BCH OAK.
