This document was created by a multidisciplinary effort among pediatric providers with the goal of providing condition/disease-specific care recommendations based on best available scientific evidence and/or consensus-based institutional recommendations. It is intended to reduce practice variation and improve the quality and safety of delivered care. These recommendations are intended to be utilized for the treatment of confirmed or suspected pediatric orbital (post-septal) cellulitis. This guideline does not replace the clinical judgment of the treating physician allowing deviation depending on unique clinical scenarios.
Orbital cellulitis (OC) is an acute infectious inflammatory process involving the tissues posterior to the orbital septum originating most often via direct spread from preceding sinus disease, skin infection, lacrimal system disease, or, less commonly, from extension of odontogenic infection, penetrating trauma or hematologic spread of a remote infection. OC may lead to formation of subperiosteal or orbital abscess, vision loss and/or extension into the central nervous system (meningitis, intracranial abscess, cavernous sinus thrombosis).
Infection is often polymicrobial in children age 9 years and older, with the most common offending etiologic bacteria being Staphylococcus aureus, Streptococcus species, Haemophilus species, and anaerobic bacteria of the respiratory tract (Peptostreptococcus and Bacteroides, Prevotella, Fusobacterium and Veillonella species). In children younger than 9 years old, it is more often a single aerobic organism. The incidence of methicillin-resistant Staphylococcus aureus depends on local resistance patterns.
Clinical features concerning for shock and/or critical illness, including toxin-mediated shock
Primary or acquired immunodeficiency, such as malignancy, drug-induced (chemotherapy, immunomodulator therapy or chronic high-dose steroids) or HIV
Recent history of surgery at the site
Environmental contamination including bite wound, presence of a foreign body or marine or freshwater exposure
Manifestations of OC can be unilateral or bilateral and suggested by the following orbital signs:
Eye pain and/or pain with extraocular eye movements
Impairment of extraocular eye movements
Proptosis
Decreased visual acuity and/or abnormal pupillary response
Conjunctival chemosis
Eyelid and periorbital edema and erythema with ptosis are signs that accompany both pre-septal and post-septal cellulitis. Systemic symptoms like fever, headache and malaise may be present with either OC or pre-septal cellulitis.
Retrograde intracranial spread can be marked by severe headaches (frontal if associated with frontal sinusitis and osteitis), nuchal rigidity and meningismus, lethargy, seizures, and altered mental status. Intracranial extension can result in meningitis, intracranial abscess, cavernous sinus thrombosis, and frontal bone osteomyelitis.
Ophthalmology
Otolaryngology (if sinus disease present)
Pediatric Infectious Diseases (ID)
Neurosurgery (if intracranial extension is present or suspected)
should be performed to establish baseline level of inflammation and evaluate end-organ function:
Complete blood count with differential (LAB293)
Renal function (LAB15)
C-reactive protein (LAB149)
Erythrocyte sedimentation rate (LAB1035)
Blood culture (Not required; consider obtaining with severe local disease or if there is concern for intracranial extension) (LAB7646)
often used to confirm the diagnosis of OC and evaluate for complications, such as subperiosteal or orbital abscess formation
Preferred initial modality: contrast-enhanced computed tomography of the orbit and sinuses
Magnetic resonance imaging with and without contrast can be used if intracranial extension (including cavernous sinus thrombosis) or radiolucent foreign bodies are suspected.
Lumbar puncture: should be considered, after assessing for signs of increased intracranial pressure, in the appropriate clinical scenario (severe headache, nuchal rigidity, meningismus, lethargy, seizures, and altered mental status) and/or in very young infants for evaluation of meningitis.
Routine Gram stain and bacterial culture of orbital/subperiosteal abscess fluid should be performed if sample is obtained.
Swabs of conjunctiva should not be sent for culture.
See above for definition and examples of intracranial extension, if unclear, consult with ID.
Vancomycin IV (dosing per UISFCH guideline), AND
Ampicillin/sulbactam 50 mg/kg/dose (dosing based on ampicillin component) IV (MAX 2 grams of ampicillin per dose) every 6 hours
OR
OR
Vancomycin IV (dosing per UISFCH guideline), AND
Ceftriaxone 50 mg/kg/dose (MAX 2 grams) IV every 12 hours, AND
Metronidazole 10 mg/kg (MAX 500 mg) IV every 8 hours
For patients with severe non-IgE mediated reactions to first-line therapies please consult pediatric infectious diseases for recommendations.
Adjust empiric antimicrobial therapy based on culture and susceptibility data.
Head of bed elevated to greater than 30 degrees to minimize dependent edema
Warm compresses to increase vasodilation
Frequent vision checks (at least every 4 hours)
Sinus protocol per otolaryngology if sinusitis present
Surgical management:
Corticosteroids:
There is insufficient evidence to routinely recommend systemic steroids for all patients with orbital cellulitis
While some studies support the safety of adjunctive corticosteroids and the potential for shorter length of stay, a recent study concluded that steroids may not reduce hospital stay and may increase 30-day readmissions in childre
Systemic steroids may be considered in select cases after discussion with all consultants
