Anesthetic Management and Outcomes of Patients With Epidermolysis Bullosa: Experience at a Tertiary Referral Center

Epidermolysis bullosa (EB) is a group of rare epithelial disorders caused by abnormal or absent structural proteins at the epidermal-dermal junction. As a result, patients experience blisters and wounds from mild shearing forces. Some forms of EB are complicated by resultant scarring and contractures. The perioperative anesthetic management of patients with EB is complex and requires a systems-based approach to limit harm. We reviewed our experience with providing general anesthesia to patients at our tertiary EB referral center, including adverse events related to anesthetic care, outcomes in the immediate perioperative period, and details of anesthetic management. We retrospectively reviewed the charts of all patients with EB anesthetized at the Children's Hospital Colorado between January 2011 and December 2016. A subset of pediatric anesthesiologists cared for all patients using a standardized clinical care pathway. Patient demographics, detailed anesthetic methods, immediate perioperative outcomes, and adverse events were characterized. Over a 6-year period, 37 patients underwent 202 general anesthetics. Most patients (75.7%) had dystrophic EB (DEB). Female patients comprised 48.6%. The majority (56.7%) traveled >50 miles to receive care, and many (35.1%) traveled >150 miles for their care. Common adaptations to care included avoidance of electrocardiogram leads (88.6%) and temperature probes (91.6%). Nasal fiberoptic intubation (n = 160) was performed, or natural airway/mask (n = 27) was maintained for most patients. Supraglottic devices were not used for airway management during any of the anesthetics. Anesthesia preparation time was longer (average 25.8 minutes [standard deviation {SD} = 12.7]) than our average institutional time (14 minutes). Succinylcholine was never used, and nondepolarizing muscle relaxants were used in only 1.5% of patient encounters. Blood was transfused in 16.3% of cases and iron infused in 24.8%. Average length of stay in the postanesthesia care unit was comparable to our institutional average (average 40.1 [SD = 28.6] vs 39 minutes). New skin or mucosal injury occurred in 8 encounters (4%), and desaturation occurred in 43 cases (21.3%). There were no major adverse events. By using a specialized team and a standardized clinical care pathway, our institution was able to minimize adverse events caused by the anesthetic and surgical care of patients with EB. We recommend natural airway or nasal fiberoptic airway management, me
