Background:
Sucking may reduce the manifestations of pain in newborn infants.
Objective:
To examine the effect of suckling on the threshold for peripheral somatosensory responses.
Subjects And Methods:
Graded Von Frey filaments were applied to the heel to initiate peripheral somatosensory responses (withdrawal reflex and gross body movements) in term infants.
Results:
Dummy sucking increases the somatosensory threshold, but breast feeding had a more marked effect, increasing the threshold of the flexion withdrawal reflex (p
Conclusion:
Peripheral sensitivity of newborn infants is considerably reduced during sucking, particularly at the breast.
