简要总结
Plan to monitor central arterial pressure in women who are undergoing spinal anesthesia for cesarean delivery or epidural anesthesia for vaginal delivery.
详细描述
Subjects will be screened as they are admitted to the maternity care floor (5th floor St. Mary's Hospital). Subjects will be approached if they are desiring regional anesthesia.
The subject will have an additional blood pressure cuff placed on the arm that anesthesia is not using for their blood pressure cuff. Central arterial pressure will be measured from the cuff:
- Prior to regional anesthesia placement
- Every 15 minutes for 1 hour
- Every 30 minutes for 2 hours Routine sphygmomanometer measurements will also completed at the above times. These are all study procedures.
Anesthesia will use their usual protocol for blood pressure monitoring and management during placement of, and after the procedure. No changes in patient management will be made based upon the central arterial pressure as the guidelines were developed with routine brachial pressure.

结局指标
主要结局
Amount of change in central arterial pressure in obesity.
时间窗: 3 hours
To determine if women who are obese undergo a larger change in their central arterial pressure than is seen by routine brachial cuff assessment, and if this effect is dependent on the level of obesity.
