Labor pain is one of the most intense pains experienced by women, which leads to an increase in the number of women opting to undergo a cesarean delivery. Pharmacological and nonpharmacological analgesia methods are used to control labor pain. Epidural analgesia is the most commonly used pharmacological analgesia method. However, it may have side effects on the fetus and the mother. Light-emitting diode (LED) photobiomodulation is an effective and noninvasive alternative to pharmacological methods.
To evaluate the effects of LED photobiomodulation on analgesia during labor.
In total, 60 women in labor admitted to a public maternity hospital will be selected for a randomized controlled trial. The participants will be randomized into 2 groups: intervention group [analgesia with LED therapy (n = 30)] and control group [analgesia with bath therapy (n = 30)]. The perception of pain will be assessed using the visual analogue scale (VAS), with a score from 0 to 10 at baseline, that is, before the intervention. In both the groups, the procedures will last 10 minutes and will be performed at 3 time points during labor: during cervical dilation of 4 to 5 cm, 6 to 7 cm, and 8 to 9 cm. At all 3 time points, pain perception will be evaluated using VAS shortly after the intervention. In addition, the evaluation of membrane characteristics (intact or damaged), heart rate, uterine dynamics, and cardiotocography will be performed at all time points.
The use of LED photobiomodulation will have an analgesic effect superior to that of the bath therapy.
分娩疼痛是女性经历的最剧烈的疼痛之一，这导致选择剖宫产的女性数量增加。药物和非药物镇痛方法用于控制分娩疼痛。硬膜外镇痛是最常用的药物镇痛方法。然而，它可能对胎儿和母亲有副作用。发光二极管（LED）光生物调节是一种有效的非侵入性药物方法替代方案。
评估LED光生物调节对分娩镇痛的效果。
总共将选择60名入住公立妇产医院的分娩妇女进行随机对照试验。参与者将被随机分为2组：干预组[LED治疗镇痛（n = 30）]和对照组[沐浴治疗镇痛（n = 30）]。疼痛感知将使用视觉模拟量表（VAS）进行评估，在基线时，即干预前，评分为0至10分。在两组中，程序将持续10分钟，并在分娩期间的3个时间点进行：宫颈扩张4至5厘米、6至7厘米和8至9厘米时。在所有3个时间点，干预后不久将使用VAS评估疼痛感知。此外，将在所有时间点评估胎膜特征（完整或受损）、心率、子宫动力学和胎心监护。
使用LED光生物调节将具有优于沐浴治疗的镇痛效果。
