About

This study aims to evaluate the effect of low-level laser in pain relief and tissue repair in mothers with nipple trauma during breastfeeding, compared to a control group.

Full description

The selection was made through the search of women hospitalized in Accommodation beds with nipple trauma, lifting of stipulated criteria, and inclusion of women in the study upon acceptance and signing of the consent form. To collect the data, a group was formed with people trained as evaluators, responsible for election, randomization, filling of First Assessment and Subsequent Assessment forms, recording of photo images and pain evaluation before and after treatment with laser; and applicators, responsible for laser handling and irradiation. Data collection followed the following order: filling of the first instrument, breast image capture, suckling observation, identification of pain during the child's breast sucking, laser irradiation and re-identification of pain during the child's breast sucking after laser treatment. The collection of data of this form occurred continuously every twelve hours until repair of the nipple trauma or patient discharge. A minimum of two and a maximum of six assessments were carried out, from the inclusion of the patient in the study (taken as zero hour) to 60 hours postpartum. Irradiation, in turn, was performed every 24 hours during the same period, including one to three irradiations per patient in each of the breasts.

Enrollment: 66 patients

Sex: Female

Ages: 18 to 45 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

Women hospitalized in the Accommodation System with their children, feeding exclusively directly from the breast and presenting unilateral or bilateral nipple trauma.

Exclusion criteria

Women who were using any other form of treatment for nipple trauma; use of any topical substance in the nipple-areola region; presence of inverted and pseudo-inverted nipple; presence of mastitis; previous history or presence of malignancies; presence of photosensitivity or any adverse reactions to exposure to sunlight; discharge planned for the first day of data collection; women under unfavorable psycho-affective and cognitive situations which prevented assessment of the analog pain scale, photo image record. and observation of breastfeeding; women who had twins, children with gestational age less than 37 weeks, or birth weight less than 2500 grams.

Treatment:

Radiation: low-level laser on nipples

low-level laser off on nipples

Placebo Comparator group

Description:

Laser with modified standard operation - shutdown of InGaAIP semiconductor diode and installation of a visible red light emitting diode with optical power of 0mW (LED - Light Emitting Diode - maximum power with standard nozzle).
