Staphylococcal Scalded Skin Syndrome

Key Points

• SSSS is caused by exfoliative toxins produced by certain strains of Staphylococcus aureus.
• Toxins target desmoglein-1 in the epidermis, causing widespread skin exfoliation (peeling).
• Most common in neonates and children under 2 years; outbreaks occur in nurseries and daycares.
• Complications include hypothermia, fluid volume loss, secondary infection, sepsis, and renal failure.

Pathophysiology

Toxin-producing strains of Staphylococcus aureus release exfoliative toxins (ETA and ETB) that cleave desmoglein-1, an adhesion molecule in the superficial epidermis. This disruption of cell-to-cell adhesion causes intraepidermal splitting at the granular layer, resulting in widespread skin exfoliation. The initial infection site is often the upper respiratory tract, conjunctivae, umbilical stump, or ears. Toxins can spread hematogenously, causing generalized involvement. Loss of the epidermal barrier leads to thermoregulation impairment, fluid loss, and increased susceptibility to secondary infection.

Clinical Manifestations

• Initial: Fever, malaise, irritability.
• Diffuse erythematous, tender rash progressing to fluid-filled blisters.
• Skin peeling in large sheets (positive Nikolsky sign: gentle lateral pressure causes skin separation).
• Mucous membranes remain unaffected (distinguishes SSSS from toxic epidermal necrolysis).
• Hypotension and signs of shock may develop.
• Potential for scarring, though most children heal well.

Nursing Assessment

NCLEX Focus

Differentiate SSSS from toxic epidermal necrolysis (TEN): SSSS spares mucous membranes and causes superficial (intraepidermal) splitting; TEN involves full-thickness epidermal necrosis and mucous membrane involvement.

• Assess extent and progression of skin exfoliation.
• Monitor vital signs: temperature (hypothermia risk), blood pressure (shock), heart rate.
• Assess fluid balance: intake and output, daily weights, mucous membrane moisture.
• Monitor for signs of secondary infection and sepsis.
• Assess renal function (complication risk).

Nursing Interventions

• Administer prescribed IV antibiotics (anti-staphylococcal agents: nafcillin, vancomycin for MRSA).
• Maintain thermoregulation: warm environment, minimize drafts, gentle handling.
• Provide meticulous wound care: sterile technique, non-adherent dressings, gentle cleansing.
• Manage fluid and electrolyte balance: IV fluid replacement as indicated.
• Minimize skin manipulation; handle the infant gently to prevent further exfoliation.
• Monitor for signs of sepsis: fever, tachycardia, hypotension, altered perfusion.
• Educate families about hand hygiene and preventing staphylococcal transmission.
