A substance given to block feeling in different parts of your child's body during and after surgery. This type of nerve block allows a lighter level of general anesthesia to be used during surgery. It also reduces your child's stress response to surgery, and allows them to recover without the stress of pain.

Regional anesthesia can be given through a single shot before surgery or delivered continuously through a catheter after surgery. A single-shot nerve block provides many hours of pain relief after surgery, while the catheter blocks nerve pain until it is removed.
