Photobiomodulation for Episiotomies and Perineal Lacerations After Vaginal Delivery.

Photobiomodulation (PBM) is a non-invasive therapy that uses low-level light, typically from lasers or Light Emission Diodes (LEDs), to stimulate cellular function and promote healing. It works by delivering specific wavelengths of light to target tissues, which enhances mitochondrial activity and increases adenosine triphosphate (ATP) production. PBM is commonly used for pain relief, reducing inflammation, and accelerating tissue repair in conditions like muscle injuries, arthritis, and skin disorders.

Medical team evaluations are conducted daily throughout the hospitalization period, and anti-inflammatory medications (ketoprofen ), analgesics (dipyrone), and, in cases where vulvar edema is observed, ice packs are prescribed. In addition to the standard treatment described, the health care team routinely offers patients the use of laser therapy (photobiomodulation) once a day during hospitalization. Patients who agree to the laser therapy receive both treatments.Patients who do not accept receiving PBM receive exactly only the same standard routine care described. These protocols are standardized at the hospital, and this observational study did not interfere with any care practices.
