Pilot Study of Sucrose to Reduce Pain in Sick Babies

Small amounts of sweet tasting sugar water reduces pain in babies during painful blood tests and injections. The investigators do not know if sugar also reduces pain in babies already receiving a continuous infusion of opioid analgesics. This project will help determine if small amounts of sugar water reduce pain in babies already receiving a continuous infusion of opioid analgesic during a heel lance procedure or nasogastric/orogastric (NG/OG) tube insertions. The investigators hypothesize that infants who are receiving opioid analgesics will have lower pain scores during their blood tests (heel lance) or NG/OG tube insertion, when sucrose is given, compared to when water is given.
