Two different anesthetic methods were employed for a patient with recessive dystrophic epidermolysis bullosa (R-DEB). One was plexus brachial block in combination with ketamine infusion. The other was general anesthesia with N2O-O2-halothane via a face mask. In the former, no particular problem developed. In the later, however, some blisters were newly formed on the region where the anesthesist's fingers were attached to hold a face mask. Although mask anesthesia was considered to be not always suitable for patients with DEB, we chose it because tracheal intubation may cause more serious damage to the upper airway leading to airway obstruction.
