Summary Background Sanfilippo syndrome ( MPS III ) is rare, with 97 cases in the United Kingdom between 1988 and 1998. Mucopolysaccharide infiltration of tissues in mucopolysaccharidosis (MPS) causes multi‐systemic pathology including difficult airways and cardiac disease. Published anesthesia case reviews of Sanfilippo syndrome have included limited numbers of patients to date. Aim To identify the perioperative management and complications of anesthesia in children with mucopolysaccharidosis Type III at Great Ormond Street Hospital. Methods A retrospective case note review of all children with MPS III in our institution was undertaken. All medical notes and anesthetic charts were analyzed, and conduct of anesthesia, airway management, perioperative complications, and associated comorbidities were identified. Results There were 43 patients with MPS III , of which 34 required anesthesia, on 86 occasions for 156 procedures between 1993 and 2015. Dental extraction was the likeliest indication for anesthesia (34%) (general surgery [30%]; ear, nose, and throat [26%]; other [10%]). Thirteen of 34 patients had cardiac pathology (valvular [ n = 6], functional [ n = 6], electrophysiological [ n = 1]). Ten of 34 patients had evidence of clotting abnormality (mild prolonged clotting time [ n = 5], low von Willebrand factor [ n = 2], thrombocytopenia [ n = 3]). The majority of intubations were Cormack–Lehane Grade 1 ( n = 47) (Grade 2 [ n = 14], Grade 3 [ n = 1], Grade 4 [ n = 1]). In 86 anesthetics, there were 0 cases of difficulty with mask ventilation. There was 1 case of failed intubation. They were subsequently anesthetized by a different operator uneventfully at a later date. Two perioperative complications occurred: a failed intubation and bleeding during adenoidectomy. Conclusion We demonstrate a difficult airway is unlikely when anesthetizing an MPS III patient although a risk does remain. A significant proportion of MPS III have cardiac involvement although no perioperative complications were described. With associated coagulation issues, bleeding tendency, while uncommon, can occur in this group.
