Effect of LED therapy for the treatment nipple fissures: Study protocol for a randomized controlled trial.

INTRODUCTION: Poor positioning of the child in relation to the breast and improper suckling are the main causes of nipple fissure. Treatment options for nipple fissures include drug therapy with antifungal and antibiotics, topical applications of lanolin, glycerin gel, creams and lotions, the milk itself, hot compresses, and silicone nipple shields. Studies involving light-emitting diode (LED) therapy have demonstrated anti-inflammatory properties, the enhancement of the wound repair process, and the control of pain. As it does not cause discomfort, is relatively inexpensive and may impede the discontinuation of breastfeeding, phototherapy could be a viable option for the treatment of nipple fissures. AIM: The principal objective of the proposed study is to evaluate the effectiveness of LED therapy for the treatment of nipple fissures in postpartum mothers. MATERIALS AND METHODS: One hundred patients treated with a medical diagnosis of bilateral nipple trauma classified as nipple fissures or cracks will participate in the study, randomized into 2 groups: The control group will receive orientation regarding breast care and adequate breastfeeding techniques. The experimental group will receive the same orientation and phototherapy sessions using a device developed especially for the treatment of nipple trauma. Both groups will be followed up for 6 consecutive weeks.

Effect of led photobiomodulation on analgesia during labor: Study protocol for a randomized clinical trial.

BACKGROUND: 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. OBJECTIVES: To evaluate the effects of LED photobiomodulation on analgesia during labor. METHODS: 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. EXPECTED OUTCOMES: The use of LED photobiomodulation will have an analgesic effect superior to that of the bath therapy.
