Measurement Requirements

This trial is evaluating whether Electrical Epidural Stimulation Test (EST) will improve 1 primary outcome and 1 secondary outcome in patients with Labor Pain. Measurement will happen over the course of Approximately 3 hours following introduction of anesthetics through the catheter..

Pain Scores
APPROXIMATELY 3 HOURS FOLLOWING INTRODUCTION OF ANESTHETICS THROUGH THE CATHETER.
Patients will be asked for a pain score by research staff approximately 3 hours following placement of the epidural catheter and low-dose anesthetics are introduced. The pain scores will be on a scale from 0-10 with 0 representing no pain and 10 representing maximum pain.
APPROXIMATELY 3 HOURS FOLLOWING INTRODUCTION OF ANESTHETICS THROUGH THE CATHETER.
Electrical Epidural Stimulation Test
DURATION OF EST TEST (APPROXIMATELY 1-2 HOURS)
Investigate the ability of the electrical epidural stimulation test (EST) to determine the position of the epidural catheter anesthesia for labour analgesia after low-dose anesthetic as compared to the gold standard of clinical assessment.
DURATION OF EST TEST (APPROXIMATELY 1-2 HOURS)

What are common treatments for labor pain?

Some common treatments for labor pain in nulliparous women have been reviewed, and are as follows (Table 2): The most common pharmacologic agents for labor pain in nulliparous women are opioids such as oxytocin (41%), methyldopa (40%), alpine acetate (26%), and fentanyl. A pessary has been known to have been used for centuries, but is rarely used now. The most common nonpharmacologic solutions for labor pain in nulliparous women are rest and relaxation techniques (41%), massage (8%), cold packs (8%), and warm hot packs (3%). Many women report experiencing improvement or complete relief when using these techniques.

How many people get labor pain a year in the United States?

In a recent study, findings suggests that the majority of pregnant women in their third trimester experience labor pain, but that it is also common for some women to be unaware of this symptom.

What is labor pain?

It is possible to make the following assumptions about labor pain: 1) some people experience pain, especially aching pain, in the first and second stages of labor. 2) women perceive more pain during the first stage of labor than during the second or third and more painful stage of childbirth (in which they have oxytocin deficiency). 3) women with premature birth are usually pain free in the first stage of labor, but have more severe pain during the second and third stages. 4) women who have epidurals are pain free earlier in labor during the first stage and less painful during the second and third stages of labor. The pain-free stage is usually short.

What is the primary cause of labor pain?

The vast majority of women with labor pain had a ruptured disk of the lumbar spine (75%), leading us to question the need for MRI in every pregnant patient.

Have there been other clinical trials involving electrical epidural stimulation test (est)?

[I]t seems that the ES is helpful for the lumbar epidural steroid injection for labor pain and [II]f there is more effective treatments for it, the ES will be reconsidered as one of the treatments for labor pain.

Anonymous Patient Answer

Has electrical epidural stimulation test (est) proven to be more effective than a placebo?

Anonymous Patient Answer

Does labor pain run in families?

Data from a recent study of our study suggest that labor pain and labor dystocia share familial determinants that may provide a potential target of prenatal treatment. However, they provide no clear evidence for or against the use of nongenetic maternal risk factors as a target for prenatal prevention of labor pain and labor dystocia.

What are the latest developments in electrical epidural stimulation test (est) for therapeutic use?

Est is safe in patients with myofascial pain syndromes, including patients with myofascial pain syndrome secondary to myositis (subacromial muscle pain associated with strenual activity of the shoulder), and is associated with significant pain relief and improved functional status in patients. A prospective randomised (blinded) controlled trial of est comparing with sham electrical stimulation, or a single session of high-energy shock wave therapy, is now required to further validate the results of this study.

What is the latest research for labor pain?

The research on the causes [of labour pain] is still rather [limited] but we are beginning to understand how genes and the [nervous system] work together to cause pain during childbirth. There is still a lot more work to be done before it will be possible to provide the safest, most loving labour that every woman wants.
