新生兒出生後即需接受一連串的疼痛處置，包括多次的足跟扎血、肌肉注射VIT　K1及疫苗注射等侵入性措施，但因無法以言語表達，常令人忽略其身體遭受的不適，乃至於誤解新生兒對疼痛的表現及因應能力，極可能留下不愉快的經驗，而影響日後心理發展。作者應用實證步驟進行文獻查證及評析結果發現，在新生兒接受侵入性措施前，若能提供母乳哺餵或餵食母乳，其疼痛生理指標、哭泣時間及疼痛量表得分顯示能減緩新生兒對疼痛的反應。經實際臨床驗證，證實扎血前給予餵食2CC的母乳，不但在扎血時心跳、呼吸速率比較平穩，還可以縮短一半的哭泣時間，證明母乳能有效減緩疼痛反應，故將其列入護理照護常規，提升新生兒臨床照護品質。

Newborns receive a series of painful interventions soon after birth. These include: heel sticks, intramuscular injections of Vit K1 and various vaccines. Nevertheless, due to the lack of verbal expression ability, the neonatal's discomfort is usually neglected or misinterpreted, leaving possible negative effects on mental developments. Our team utilized evidence-based medicine(EBM) in the survey and found out that prior to invasive procedures, if the neonates could be fed with breast milk or directly breast-fed, the pain reaction could be alleviated, as evidenced by physiological pain index, crying time and pain scale. Through our clinical practice, we proved that the administration of 2 cc of breast milk before heel sticks not only led to a more stable heart rate and respiratory pattern during the procedure, but also shorten half of the baby's crying time after the procedure. These proved that breast milk can reduce pain reaction of newborns. We suggest to list breast milk feeding before invasive procedure as a standard nursing routine to provide a better clinical care for newborns.
