Parameters of anesthesia/sedation in children receiving radiotherapy

Previous reports establish low risk of complications in pediatric treatments under anesthesia/sedation (A/S) in the outpatient setting. Here, we present our institutional experience with A/S by age and gender in children receiving daily proton RT. After Institutional Review Board approval, we reviewed our center's records between 9/9/2004 and 6/30/2013 with respect to age and gender of A/S requirement in our pediatric patients (defined as patients ≤18 years of age). Of 390 patients treated in this era, 182 were girls. Children aged ≤3 invariably required A/S; and by age 7–8, approximately half of patients do not. For pediatric patients ≥ 12 years of age, approximately 10% may require A/S for different reasons. There was no difference by gender. Beyond age 3, the requirement for A/S decreases in an age-dependent fashion, with a small cadre of older children having difficulty enough with sustained immobilization that A/S is necessary. In our experience, there is no difference in A/S requirement by gender
