Photobiomodulation for Episiotomies and Perineal Lacerations After Vaginal Delivery.
Sponsor: University of Nove de Julho
Summary
Episiotomies (EP) and perineal lacerations (PL) following vaginal delivery can lead to complications such as pain, edema, and infection. Currently, anti-inflammatory drugs, analgesics, baths, and ice packs are recommended for treatment. Photobiomodulation therapy (PBM) has emerged as a promising technology for pain management and scar healing in EP and PL. This is a cohort observational study conducted at the Maternal and Child University Hospital of the Universidade Estadual de Ponta Grossa, Paraná, Brazil. PBM adjuvant therapy is routinely applied at the bedside daily throughout the postpartum hospitalization. PBM is routinely offered to all postpartum patients during hospitalization. Patients may choose to accept or decline the use of analgesic PBM in addition to the standard therapeutic measures provided by the hospital (anti-inflammatory drugs, analgesics, baths, and ice packs). All patients who underwent EP or suffered grade 2 and 3 PL over six months are evaluated. We will analyze the data from patients who accepted the use of PBM and those who declined the use of PBM regarding the presence of pain, local healing of perineal lacerations, and episiotomies. The primary outcome is the daily pain assessment using the Numerical Pain Scale (NPS) before and after PBM (hospital standard). The secondary outcome is the evaluation of perineal healing using the REEDA scale. Initially, data distribution will be tested using the Kolmogorov-Smirnov test. Comparisons of NPS and REEDA scores between groups that received laser therapy and those that did not received will be performed using repeated-measures ANOVA, considering study covariates. Epidemiological and clinical data (age, sex, marital conditions, type and characteristics of labour (spontaneous or induced), newborn weight, presence of clinical complications during hospitalization ) collected directly in the patients' medical records to characterize the sample. All analyses will be conducted using SPSS 24.0 software, with a significance level of 95%.

Interventions
Photobiomodulation Therapy
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.
Hospital Standard Protocol of treatment for pain and healing
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.
