The Effect of Kangaroo Care on Pain in Infants Receiving Phototherapy

Kangaroo care is a highly effective, low-cost, and feasible method for reducing crying duration and alleviating pain in newborns. This method is most commonly provided by the mother. However, the World Health Organization states that when the mother is unable to participate, kangaroo care may also be provided by other family members, such as the father or grandmother, a close friend, or a trained healthcare professional. Particularly in neonatal intensive care unit settings, it is not always possible for mothers to remain continuously with their infants outside visiting hours. During periods when the mother is unavailable, nurses may be considered as alternative providers of kangaroo care for pain management; however, due to the limited scientific evidence on this topic, the effectiveness of nurse-provided kangaroo care remains unclear. By addressing this gap in the literature, the present study aims to examine the effect of nurse-provided kangaroo care on neonatal pain levels and to contribute to the field of neonatology as an atraumatic care practice.

Newborns participating in the study will be randomly assigned using a simple randomization method to three groups: experimental group 1 (mother-provided kangaroo care), experimental group 2 (nurse-provided kangaroo care), and the control group. Newborns in experimental group 1 will receive kangaroo care by being placed, wearing only a diaper, in direct skin-to-skin contact with their mother's bare chest. The intervention will be initiated 15 minutes before the heel-prick blood sampling procedure, maintained throughout the procedure, and continued for an additional 15 minutes after the procedure. To eliminate the potential effects of hunger or satiety on neonatal pain responses, all newborns will be fed at least 30 minutes prior to the procedure.

Physiological parameters, including oxygen saturation (SpO₂), heart rate, respiratory rate, and body temperature, will be measured and recorded using a monitor before the procedure (0 minute), during the procedure, and at 2 and 10 minutes after the procedure. Phototherapy will not be interrupted during the procedure. Heel-prick blood sampling will be performed by a neonatal intensive care unit nurse after cleansing the puncture site with 70% alcohol and allowing it to dry, using an automatic lancet routinely employed in the unit.

Pain levels and crying duration will be assessed using video recordings obtained before, during, and after the procedure (at 2 and 10 minutes). These recordings will be evaluated after completion of the procedure by both the researcher and an independent observer (a neonatal intensive care unit nurse) using the Neonatal Infant Pain Scale (NIPS), and the results will be recorded on the observation form. Newborns in experimental group 2 will receive nurse-provided kangaroo care, and all intervention, measurement, and evaluation procedures will be conducted in the same manner as in experimental group 1. Newborns in the control group will undergo heel-prick blood sampling in a standard position within an incubator, in accordance with routine hospital practices, without the application of kangaroo care; all measurement and evaluation procedures will be conducted in the same manner as in experimental groups 1 and 2.

If the results of the study demonstrate that mother-provided kangaroo care is more effective, recommendations may be developed to strengthen family-centered care practices. Alternatively, if nurse-provided kangaroo care is shown to produce comparable effects, nurses may be encouraged to incorporate this method into neonatal care protocols as a standard practice in situations where the mother is unavailable, deceased, or unable to provide kangaroo care. Through this study, non-pharmacological pain management strategies may be updated, thereby contributing scientifically to neonatal care through nurses' implementation of atraumatic care practices. In addition, the findings of this study may provide a foundation for future research.
