Newborn screenings are crucial preventive health services within public health programs worldwide. In our country, as part of this program, heel blood is taken from newborns between the 48th and 72nd hours after birth, which causes pain and discomfort in newborns. Non-pharmacological methods are frequently utilized to relieve the pain caused by heel blood collection in newborns and to improve comfort during the procedure. One of these methods is kangaroo care, also known as skin-to-skin contact. Kangaroo care involves placing the baby in direct skin contact with the mother, which helps regulate the babys body temperature, calm the baby, and fosters bonding between mother and baby. This method, also described as human incubator care requires no special skills, is cost-effective, and is reported to have significant benefits in reducing procedural pain. In the literature, apart from the classic kangaroo position where the babys chest touches the mothers chest, there are studies describing alternative positions such as side kangaroo (kangaroo-supported diagonal flexion) and reverse kangaroo (supine kangaroo). The side kangaroo position differs from the classic kangaroo care in that the baby is held crosswise with its neck supported by the mother, allowing mother and baby to face each other. The reverse kangaroo position is a modified version of the classic kangaroo position, where the baby, wearing only a diaper, is placed upright with its back in contact with the mothers bare chest. Skin-to-skin contact during kangaroo care has a calming effect, reducing both physiological and behavioral pain responses in the baby. Therefore, it is thought that different kangaroo positions, which maintain skin-to-skin contact between the baby and the mother, may affect pain, comfort, physiological parameters, and crying durations during the heel blood collection procedure. Additionally, in cases where the classic kangaroo position cannot be used, these positions may serve as alternative methods. Upon reviewing national and international literature, no studies were found comparing the effectiveness of different kangaroo positions during heel blood collection in term newborns. Thus, this study aims to compare the effects of classic kangaroo, side kangaroo, and reverse kangaroo positions on pain, comfort, and physiological parameters (heart rate, oxygen saturation) in term newborns. Secondary outcomes of the study include evaluating the crying duration of newborns and the procedure duration for heel blood collection.
