What is the purpose of this trial?

This trial tests whether Epsom salt compresses can reduce perineal pain after childbirth. Researchers will compare the effectiveness of Epsom salt compresses to plain water compresses. Participants may use the compresses up to four times a day while in the hospital. Women who have given birth vaginally and are staying in a specific hospital might be suitable candidates. As a Phase 2 trial, the research focuses on measuring the treatment's effectiveness in an initial, smaller group of people.

Do I need to stop my current medications for this trial?

The trial information does not specify whether you need to stop taking your current medications. It might be best to discuss this with the trial coordinators or your doctor.

Is there any evidence suggesting that Epsom salt compresses are likely to be safe for postpartum perineal pain relief?

Research has shown that Epsom salt compresses, containing 25% magnesium sulfate, may help reduce pain after childbirth. A recent study found that applying magnesium sulfate to the skin decreased the intensity and duration of labor pain, suggesting it might also alleviate post-birth pain.

Epsom salts are generally safe for skin use and have been part of health treatments for many years. There are no major reports of negative effects from similar skin applications. As this is an early-phase trial, the researchers are still testing its safety for this specific use, but past experiences provide some reassurance. Participants in the trial will likely be asked to report any side effects experienced. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Researchers are excited about Epsom salt compresses for postpartum perineal pain because they offer a natural alternative with a unique active ingredient—magnesium sulfate. Unlike typical treatments like pain relievers or ice packs, Epsom salt compresses use magnesium's anti-inflammatory properties to potentially ease pain and swelling more effectively. This treatment is also non-invasive and easy to apply, making it a convenient option for new mothers seeking relief.

What evidence suggests that Epsom salt compresses might be an effective treatment for postpartum perineal pain?

Research has shown that magnesium sulfate, or Epsom salt, can help reduce pain. A recent study found that applying magnesium sulfate to the skin significantly reduced the length and intensity of labor pain. Although this study focused on labor pain, it suggests that Epsom salt might also alleviate other types of pain, such as postpartum discomfort. In this trial, one group of participants will receive Epsom salt compresses, while another group will receive a placebo treatment with sterile water. Warm compresses are already known to help with postpartum pain, and adding Epsom salt might enhance their effectiveness. Researchers are investigating Epsom salt compresses for postpartum care, aiming to provide similar pain relief. ^{1 2 4 5 6}

What Are the Treatments Tested in This Trial?

Interventions

• Epsom Salt Compresses

Trial Overview

The trial tests if Epsom salt compresses (25% magnesium sulfate) can relieve postpartum perineal pain compared to placebo (water-soaked compresses). Women will use these compresses up to four times daily during their hospital stay and record their pain levels.

How Is the Trial Designed?

Group I: Magnesium sulfate Active Control 1 Intervention

Patients in the first group will receive an amber bottle of 250 milliliters containing treatment.The treatment is a solution of MgSO4 25% with sterile water base (Epsom salt solution, concentrated to 25% \[SSE25\]).

Group II: Water Placebo Group 1 Intervention

Patients in the second group will receive an amber bottle of 250 milliliters containing the placebo.The placebo is sterile water.

Epsom Salt Compresses is already approved in United States, European Union for the following indications:

Approved in United States as Magnesium sulfate for:

• Relief of perineal pain and swelling postpartum

Approved in European Union as Magnesium sulfate for:

• Relief of perineal pain and swelling postpartum

Published Research Related to This Trial

In a study of 237 women with postpartum perineal pain, ibuprofen (400 mg) and acetaminophen with codeine (600 mg) were found to have similar pain relief effectiveness, with mean pain ratings of 3.4 and 3.3 respectively.

However, ibuprofen was associated with significantly fewer side effects (52.4% vs. 71.7%) compared to acetaminophen with codeine, making it a potentially safer and more cost-effective option for managing postpartum pain.

Perineal trauma and pain are common after vaginal birth, and midwives can play a crucial role in helping mothers manage this discomfort, which can affect their transition to motherhood.

Local anaesthetic agents are highlighted as effective tools for relieving perineal pain, suggesting a need for further research to enhance postnatal care practices.

A systematic review of 17 randomized controlled trials involving 1132 women found that a single dose of aspirin significantly improves pain relief for postpartum perineal pain compared to placebo, with a risk ratio of 2.03, indicating more women experienced adequate pain relief.

Aspirin also reduced the need for additional pain relief without increasing maternal adverse effects, although the evidence quality was low, and the studies did not include breastfeeding women, limiting applicability to current postpartum care guidelines.

An implementation study in a public maternity hospital in São Paulo showed that strategies like professional training and care protocols significantly improved compliance with evidence-based practices for managing perineal pain in new mothers.

After the intervention, audits revealed that nursing care practices for perineal pain management improved, indicating that the strategies effectively enhanced the quality of care based on scientific evidence.

In a study of 50 women who had vaginal deliveries with episiotomy, the median perineal pain reported was 5 on a Numeric Scale, indicating moderate pain levels in the postpartum period.

The study identified that perineal pain was characterized by various sensations such as pulsing and stinging, and significantly limited activities like sitting, lying down, and walking.
