Monitoring at Home Before and After Adenotonsillectomy



While adenotonsillectomy is a very safe procedure, recent research has highlighted that in rare cases children can have breathing problems after the operation. These breathing problems can be made worse in certain cases by using strong medicines like morphine after the operation. The purpose of this study is to to record and evaluate overnight monitoring for three nights before surgery and three days directly after surgery with the Phone Oximeter. We are hopeful that we can use this data to help design a mobile device application to predict which children could develop breathing problems after their operation.
