Epidermolysis Bullosa


Risk

  • 1:17,000, 50% dystrophic form

  • Racial distribution equal

Perioperative Risks

  • Difficult IV access, airway, intraop positioning, reflux, steroid dependence, intraop hemorrhage, sepsis, iatrogenic corneal abrasion, blister formation, and airway obstruction

Worry About

  • Problems similar to those found in pts with severe skin burns; severely compromised pts

  • Difficult intubation (23%) secondary to microstomia

  • Establishing monitoring and IV access

  • Dehydration and malnutrition

  • Anemia, hypoalbuminemia, electrolyte imbalance, and thrombocytosis

  • Septicemia

  • Renal and adrenal dysfunction

Overview

  • Characterized by epithelial blistering resulting from minor trauma by lateral shearing forces, not pressure, because of absence of normal intracellular bridges caused by collagen abnormality

  • Four types: SEB, JEB, DEB, and Kindler syndrome

  • Associated conditions: Growth retardation, pyloric stenosis, esophageal stricture, pseudosyndactyly, enamel hypoplasia, muscular dystrophy, squamous cell carcinoma, and malignant melanoma

  • SEB: Most common form; intraepidermal blisters on the soles and palms only in Weber-Cockayne form, generalized in Kobner form, generalized herpetiform in Dowling-Meara form, and generalized in association with muscular dystrophy in the MD form

  • JEB: Blisters formed in the intralamina lucida and in intertriginous areas in the inversa form, which are generalized with growth retardation in the Herlitz form, generalized without growth retardation in the non-Herlitz form, and generalized with pyloric atresia

  • DEB: Blisters formed in the sublamina densa and in intertriginous areas in the inversa form, on ankles in the pretibial form, on arms and legs in the pruriginous form; generalized blisters in the non–Hallopeau-Siemens form and with growth retardation and severe extracutaneous involvement in the Hallopeau-Siemens form, and aggressive squamous cell carcinomas (very commonly)

  • Kindler syndrome: Blisters formed at multiple levels, intralamina lucida and sublamina densa; Kindler syndrome (previously considered as poikilodermatous photosensitivity disease); skin findings including atrophic scarring and nail dystrophy; possibly associated with severe colitis, esophagitis, urethral strictures, and ectropions; squamous cell carcinoma (can develop)
