Chapter 49: The Child With an Alteration in Tissue Integrity

The pediatric skin is structurally thinner with reduced epidermal-dermal adhesion, immature sweat gland function, and greater permeability, creating vulnerability to transepidermal fluid loss and impaired thermoregulation. The chapter details the skin's protective barrier function, sensory capabilities, and role in vitamin D synthesis while addressing how developmental immaturity compromises these functions in infants. Neonatal skin variations are systematically categorized into benign transient markings such as salmon patches and Mongolian spots versus clinically significant vascular lesions including port-wine stains and infantile hemangiomas, some requiring intervention or indicating syndromic associations. Inflammatory dermatoses are explored comprehensively, with emphasis on seborrheic dermatitis, contact dermatitis, and diaper-related skin breakdown mechanisms, highlighting moisture barrier maintenance as preventive strategy. Atopic dermatitis receives substantial focus as a chronic inflammatory condition with genetic predisposition and immune dysfunction underlying the persistent pruritus-scratch-infection cycle, complicated by secondary bacterial colonization including impetigo. The chapter progresses through infectious conditions including bacterial cellulitis, fungal dermatophyte infections, and viral herpes simplex presentations, each requiring distinct pharmacological and isolation protocols. Parasitic infestations of pediculosis and scabies are addressed with emphasis on environmental decontamination and complete eradication protocols. Adolescent acne vulgaris is examined within the context of hormonal physiology, sebaceous gland hyperactivity, and significant psychosocial morbidity during identity development. The final major section addresses pediatric burn injuries with classification of thermal injury depth from first-degree superficial through fourth-degree full-thickness destruction, age-specific vulnerability factors, and systemic consequences including hypovolemic shock and multi-organ involvement. Critical nursing priorities encompass fluid resuscitation calculations, wound management, infection prevention, and long-term rehabilitation to minimize contracture formation and psychological trauma associated with visible scarring.
