Ketamine Tolerance in Children After Repeated Administrations During Radiotherapy Sessions

Summary

Ketamine provides a safety zone for sedated but spontaneously ventilated children especially in remote conditions such as radiotherapy units where sedation is an essential practice for children to keep calm and motionless In this study, investigators planned to analyse ketamine doses needed and the recovery times in pediatric oncology patients undergoing repeated radiotherapy sessions.
