So, if being responsive or lacking immobility will prevent successful completion of procedure, deep sedation or general anesthesia will be necessary.
Further, since children have higher tendency to not be able to comply without being rendered unresponsive, pediatric procedures often requires deep or general anesthesia.
Unfortunately young children may be at increased risk of needing "rescue" from adverse effects of anesthesia (i.e. compromised breathing), so it is imperative that this treatment occurs only in an environment staffed, equipped
and trained to manage and treat these adverse events.
