The Effect of Sacral Massage and Sterile Water Injection During Childbirth on Pain Level and Birth Satisfaction (Satisfaction)

July 13, 2026 updated by: Hilal Guveri, Cumhuriyet University
Childbirth is a physiological, psychological, and social process. Ineffective management of lower back pain during labor reduces oxygen supply to the fetus, increasing hypoxia, distress, perinatal morbidity, and mortality rates. Non-pharmacological approaches such as massage, breathing techniques, sterile water injection, aromatherapy, hydrotherapy, transcutaneous nerve stimulation, and acupressure are used to reduce pain during childbirth. Sterile Water Injection (SSI) is one of the non-pharmacological methods applied to reduce lower back pain during childbirth. Injecting sterile water into the skin acts as a pain stimulant that alters pain perception in women experiencing severe back and lower back pain during labor. SSI is considered an attractive and current method for reducing lower back pain during childbirth due to its lack of side effects and risk to the fetus. Sacral massage, on the other hand, is applied to pregnant women, usually in the form of back or sacral massage, to reduce pain perception and increase comfort during childbirth. The mechanism of action of both Sterile Water Injection and sacral massage applied to the sacral region is the same and bypasses the gate mechanisms expressed by gate control theory. It prevents the pain-causing agent from passing through the "door," thus preventing the pain stimulus from reaching consciousness. Sacral massage and sterile water injection applied during labor stimulate the central nervous system, causing a number of hormonal changes. Furthermore, the central nervous system stimulates oxytocin release, leading to mental detachment from pain and reduced anxiety. Therefore, women giving birth can tolerate pain better. Birth satisfaction is crucial for maintaining maternal and infant health. The provision of quality healthcare services is directly proportional to a positive birth experience and maternal satisfaction. Since sterile water injection and sacral massage are low-cost interventions with no side effects for the mother and fetus, they can be easily applied to alleviate labor pain among women giving birth. The literature shows a limited number of studies comparing sterile water injection and sacral massage in the sacral region during labor. This study will be conducted to determine the effect of sterile water injection and sacral massage applied to the sacral region on labor pain and satisfaction in pregnant women.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Visual analog scale (VAS) score for labor pain
Time Frame: During labor at 6 cm, and 10 cm of cervical dilations.
The VAS is a 10-cm horizontal line leadership tool used to measure pain intensity. Scores range from 0 (no pain) to 10 (worst possible pain). Higher scores indicate more severe pain.
During labor at 6 cm, and 10 cm of cervical dilations.
