What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now

Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This trial tests whether photobiomodulation, a low-intensity light therapy, can reduce pain and improve healing of the surgical incision after a cesarean section. Researchers will enroll 30 women undergoing cesarean delivery and randomly assign them to receive either active light therapy or a placebo device, in addition to standard hospital care. The light is applied to the wound area right after surgery and again at 24 and 48 hours. Pain levels and wound healing are measured at several points up to 40 days after birth, using standard scales.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Photobiomodulation (PBM), a low-intensity light therapy applied to the cesarean incision
What this could lead to
If it works, this could offer a drug-free way to reduce post-cesarean pain and improve wound healing, potentially speeding recovery for new mothers.
What could go wrong
This is a small, early-stage trial with only 30 participants, so results may not apply broadly. The therapy is unlikely to replace standard painkillers and may only provide modest benefits.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Women undergoing cesarean section, regardless of whether indicated during labor or electively by maternal request; * Under follow-up at the Mandaqui Hospital Complex "Bispa Keila Campos Costa Ferreira" by the local Obstetrics team; * Admitted to the Hospital for delivery (either by referral or spontaneous demand) with adequate prenatal care (minimum of 7 visits); * Aged between 18 and 45 years; * Have undergone adequate prenatal follow-up; * Have a mobile phone with internet access and a video-calling application. Exclusion Criteria: * Women with multiple gestation; * Women with uncontrolled systemic diseases; * Women with active infectious conditions as an indication for pregnancy resolution (e.g., patients with chorioamnionitis); * Women with a prior diagnosis of coagulation disorders; * Women with grade 3 obesity (BMI ≥ 40 kg/m²); * Women with photosensitivity; * Women with more than 2 previous cesarean sections (repeated/recurrent cesareans). * Women who, at the time of delivery, did not receive intraoperative prophylactic antibiotic therapy, who present secondary skin lesions from recent local shaving/trichotomy, or who were not submitted to preoperative surgical site degerming/preparation (all of which are measures that impact the reduction of surgical site infection risk); * Parturients who presented clinical complications during the immediate pre-hospital, intra-hospital, or intrapartum period.
