Does Ultrasound of the Spine Improve Labor Epidurals/Spinal Anesthesia in

Status Withdrawn

Clinical Trial Summary

The investigators are interested in determining the utility of ultrasound of the spine for labor epidurals or spinal anesthesia for women in labor or having a cesarean delivery. The investigators hypothesized that in women with poor spinal landmarks that the use of ultrasound of the spine will improve the process of placing labor epidurals or spinal anesthetics

Clinical Trial Description

Ultrasound has been in use for peripheral regional anesthesia for several years and is becoming more common. It is currently routinely used here at the University of Missouri. Ultrasound for neuraxial anesthesia, however, is less common and is only being done in a few centers.. There have been several case reports of its use in obstetric anesthesia for patients with prior spinal surgery or spinal deformity. There have been even few prospective randomized studies. While its use may have significant advantages, it is not yet clear what those advantages are and in whom it may be most beneficial. The investigators seek to answer the following questions regarding the use of preprocedure ultrasound for neuraxial analgesia/anesthesia in obstetric patients:

- Are there benefits to the use of pre procedure ultrasound for neuraxial analgesia/anesthesia?

- If so, what are the benefits?

- If measurable, to what extent does the patient benefit?

- Do all patients benefit or only a specific subgroup?

- Is there a "cost" to the use of pre procedure ultrasound, i.e. extra time needed to perform the ultrasound exam vs a "savings" with the use of pre procedure ultrasound, i.e., less time to perform the epidural analgesic or spinal anesthetic as a direct result of the use of ultrasound?

- In particular the investigators hypothesize that in patients whose spinal landmarks are not palpable or are barely palpable, ultrasound will be found to be beneficial as determined by metrics described below (see item #6). In patients whose landmarks are prominent or easily palpable pre procedure ultrasound will not be of significant benefit. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
