In the 2003 article “Kangaroo Care Is Effective in Diminishing Pain Response in Preterm Neonates”, Celeste Johnston, Bonnie Stevens, Janet Pinelli, and their colleagues evaluate the effectiveness of the Kangaroo Mother Care position in decreasing the pain response of preterm infants who undergo a heel lance procedure for blood collection. Kangaroo Mother Care is a method of treatment for premature and low birth weight infants that involves exclusive breastfeeding and skin-to-skin contact between a mother and her infant in what is called the kangaroo position. After researchers supported the use of Kangaroo Mother Care for basic care, they began to search for other uses of Kangaroo Care in the neonatal intensive care unit, or NICU. In their article, the authors demonstrate that the skin-to-skin contact involved in the Kangaroo Mother Care decreased the amount of pain premature infants experienced during a heel lance, a frequently used NICU procedure.
