Pain accruing from nipple lesions caused by inadequate latching by the baby is a common complaint among breastfeeding women and an important obstacle to successful breastfeeding. Nipple pain occurs during the first days after delivery and is considered one of the main causes for early weaning. To investigate the efficacy of low-level laser therapy as a treatment for nipple pain due to breastfeeding. A triple-blind, randomized, clinical study. A university-affiliated hospital in São Paulo, Brazil. Fifty-nine women with nipple lesions at the time of their admission. Thirty women (intervention group) received three sessions of laser therapy (InGaAIP laser, 660 nanometer, 40 milliwatts of power, 5 Joules per square centimeter of energy density for 5 seconds each, total energy = 0.6 Joules) in the region of the nipples at three different points in time (0 hour, 24 hours, and 48 hours after diagnosis of nipple lesion). Twenty-nine women with similar clinical conditions were randomly assigned to the control group. Self-reported pain was recorded before and after laser therapy using a visual analogue scale. The intervention group experienced a decrease of 2.0 centimeters in intensity of pain (p = .016) 24 hours after the first intervention and also presented lower levels of pain compared with the control group. Low-level laser therapy was considered effective for treating nipple lesions in breastfeeding women with pain, providing relief and prolonging exclusive breastfeeding. More clinical trials with different laser dosimetry and parameters are necessary to optimize laser therapy protocols for breastfeeding women.
因婴儿 latch 不当导致乳头损伤而产生的疼痛是母乳喂养女性常见的抱怨，也是成功母乳喂养的重要障碍。乳头疼痛发生在分娩后的头几天，被认为是早期断奶的主要原因之一。为了研究低强度激光疗法治疗母乳喂养引起的乳头疼痛的疗效。一项三盲、随机、临床研究。巴西圣保罗一家大学附属医院。59名入院时患有乳头损伤的女性。30名女性（干预组）在三个不同时间点（乳头损伤诊断后0小时、24小时和48小时）在乳头区域接受了三次激光治疗（InGaAIP激光，660纳米，40毫瓦功率，每平方厘米能量密度5焦耳，每次5秒，总能量 = 0.6焦耳）。29名临床情况相似的女性被随机分配到对照组。使用视觉模拟量表在激光治疗前后记录自我报告的疼痛。干预组在第一次干预后24小时疼痛强度降低了2.0厘米（p = 0.016），与对照组相比疼痛水平也更低。低强度激光疗法被认为对治疗有疼痛的母乳喂养女性的乳头损伤有效，能缓解疼痛并延长纯母乳喂养时间。需要更多不同激光剂量测定和参数的临床试验来优化母乳喂养女性的激光治疗方案。 （注：文中“latch”可能是医学术语中关于婴儿含接姿势之类的专业表述，这里直接保留英文未准确翻译，因为不太明确其在医学语境下的确切含义。）
