To the Editor.
Blass and Hoffmeyer1 are to be congratulated for documenting the simple noninvasive use of a sucrose-flavored pacifier to relieve pain in newborns. In well-controlled studies they showed that not only did this benign therapy decrease distress during blood collection for routine newborn screening, but it also reduced crying more than 50% during circumcision. Earlier work by Blass and others indicated that a pacifying stimulus as well as oral sucrose relieves pain2-4 and that this analgesic effect is mediated through opiate pathways.5-7
