Neuraxial Anesthesia and Restless Leg Syndromes in Cesarean (NARELESS)

July 26, 2011 updated by: Nanjing Medical University

Correlation of Neuraxial Anesthesia and Restless Leg Syndromes in Cesarean Delivery

The restless leg syndromes is a common sensorimotor disorder of unknown cause affecting approximately 10% of the population. Different literature had different views on the association between neuraxial anesthesia and the occurrence of restless leg syndrome. Some reported that spinal anesthesia induced postoperative restless leg syndrome, but other studies showed that spinal and general anesthesia all two did not cause restless leg syndrome. A potential difference amongst these studies is that a big difference exists in surgical types. The investigators proposed that different types of surgery performed undergoing various anesthesia, and that there is a big difference in original pathophysiological condition. Therefore, the investigators hypothesized that pregnant women who have special physical states would have had an association between neuraxial anesthesia and restless leg syndrome in such patients who received selective cesarean section undergoing spinal or epidural anesthesia.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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
Time Frame
Occurrence of restless leg syndrome
Time Frame: One day to one week after completion of cesarean
One day to one week after completion of cesarean

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
