BackgroundMucopolysaccharidoses (MPS) are hereditary storage diseases; airway management typically worsens in these patients with the progression of the disease.Objective(S)To assess the incidence of perioperative complications in children with MPS and the impact of enzyme replacement therapy (ERT) followed by hematopoietic stem cell transplantation (HSCT).MethodsThe records of patients with MPS treated with ERT followed by HSCT, who received anesthesia at the Wilhelmina Children's Hospital between 2003 and 2012, were reviewed. Data were collected on incidence of perioperative respiratory and cardiovascular complications and the impact of treatment and age.ResultsNineteen children with MPS were identified (including 17 Hurler patients), who received ERT treatment followed by HSCT. Median age at start of treatment was 14 (range: 7-43) months. Patients were anesthetized 136 times. The incidence of respiratory and cardiovascular complications was 24% and 4%, respectively. Airway management by face mask was difficult in 7%. There were no problems with the laryngeal mask airway. Tracheal intubation was difficult in 25% and failed in 10%; using a video laryngoscope was most successful (89%), followed by classic laryngoscope (67%) and fiber-optic scope (20%). Multivariate logistic regression analyses showed that the incidence of perioperative respiratory problems did not increase with age or decrease after start of treatment.ConclusionPerioperative airway management was most successful using a laryngeal mask airway or video laryngoscope. Treatment with ERT followed by HSCT and patient age did not influence the incidence of perioperative respiratory problems.© 2014 John Wiley & Sons Ltd.
