Infants do not routinely receive acetaminophen for pain control after circumcision. This
study will determine if acetaminophen is effective at controlling infant pain after
circumcision using nerve block and oral dextrose. Infants will undergo the routine
circumcision procedure, and half will be randomly selected to receive half acetaminophen
immediately at the end of the procedure. Afterwards, infant's vitals signs (heart rate,
respiratory rate, oxygen saturation), the neonatal infant pain scale (NIPS), and salivary
cortisol levels will be checked in regular intervals up to 4 hours. The NIPS is a validated
pain scoring system based on the appearance of the infant. A reduction in NIPS for those
infants who receive acetaminophen versus nothing will be the primary outcome to determine if
the study is significant.
