December 21, 2016 updated by: Zeyong Yang, Fudan University

Safety and Risk Assessment of Obese Parturient Underwent Cesarean Section(CS) Delivery Under General Anesthesia or Intraspinal Anesthesia

900 parturient who underwent CS under general anesthesia(GA) , intraspinal anesthesia included epidural anesthesia(EA) and combined spinal-epidural anesthesia(CSEA), which were divided into 3 groups: Morbid Obesity group (n=300) with body mass index (BMI) >40 kg/m2 , severe Obesity group (n=300) with 30 kg/m2≤BMI ≤40 kg/m2 and non-Obesity group(n=300) with BMI<30 kg/m2. Findings Between January 1, 2013 and September 30, 2016, a total of 1000 women met inclusion criteria and 900 women received allocated intervention. All patients were divided into three groups: Morbid Obesity group(n=300), Severe Obesity group(n=300) and non-Obesity group(n=300) according to body mass index (BMI) >40 kg/m2, 30 kg/m2≤BMI ≤40 kg/m2 and BMI<30 kg/m2.900 patients completed the protocol and related data were analysed.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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

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.
900

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.

Ages Eligible for Study

24 years to 35 years (ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

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
Patients numbers of obese parturient complications
Time Frame: 2 years
Patients numbers of emergency, fetal macrosomia, gestational diabetes mellitus (GMD), CS history, fetal distress, elderly parturient women(≥35 years), prenatal fever, arrhythmias, abnormalities of the heart, hypertension(pre-eclampsia), multiple pregnancy, precious child, amniotic fluid abnormality, amout of bleeding, neonate Apgar's Score(1min), Apgar's Score(5min), and patients numbers of EA, GA, PACU (Postanesthesia Care Unit ) and ICU (Intensive Care Unit) for duration of hospital stay and anesthesia puncture times with 5>n≥3 and n≥5 in three groups included non-Obesity group, severe Obesity group and Morbid Obesity group were also recorded. In addition, we also recorded puncture patients numbers in sitting position for all groups.

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
