Overview
Brief Summary
The purpose of this pilot trial is to examine the feasibility and ease of use of monitoring by ClearSight in laboring and delivering patients with the intent to compare time-to-treatment of hypotension between conventionally monitored patients (Group CM) and those receiving HPI (Group CM + HPI) monitoring by ClearSight, in a population of healthy laboring women who receive epidural analgesia.
Detailed Description
In a prospective study, we will achieve the following aims: To determine the feasibility and ease of use of the ClearSight monitoring system in the labor-delivery room (LDR) in detecting and monitoring hypotensive events post-epidural labor analgesia placement. To compare the Time-to-Treatment of hypotensive events between the conventionally monitored patients (Group CM) and those receiving HPI (Group CM + HPI) monitoring by ClearSight.

Outcomes
Primary Outcomes
Time-to-treatment of Hypotension (Minutes)
Time Frame: From epidural placement until 4-hours post-infusion start
The difference in time between diagnosis of hypotension and treatment by clinical staff between CM and HPI groups
Ease of Use by Clinical Staff
Time Frame: report at 4-hour post-infusion
Clinical nurse reports of ease of use of ClearSight device. This outcome will be measured on a Likert Scale (0-4) with the options being: 0-Completely Disagree, 1-Disagree, 2-Neither agree nor disagree, 3-Agree, 4-Completely Agree. Outcome measure will be reported as count of participant's responses per category. For this scale, the objective was to obtain agreeable response feedback (score of 3 or 4). The specific question to measure ease of use by clinical staff was: "The ClearSight blood pressure monitoring device seems easy to use."
Ease of Hypotension Detection by Clinical Staff
Time Frame: report at 4-hour post-infusion
Clinical nurse reports of ease of hypotension detection using ClearSight device. This outcome will be measured on a Likert Scale (0-4) with the options being: 0-Completely Disagree, 1-Disagree, 2-Neither agree nor disagree, 3-Agree, 4-Completely Agree. Outcome measure will be reported as count of participant's responses per category. For this scale, the objective was to obtain agreeable response feedback (score of 3 or 4). The specific question to measure ease of use by clinical staff was: "The ClearSight blood pressure monitoring device seems suitable."
Satisfaction of ClearSight Use by Clinical Staff
Time Frame: report at 4-hour post-infusion
Clinical nurse reports of satisfaction of use of ClearSight device. This outcome will be measured on a Likert Scale (0-4) with the options being: 0-Completely Disagree, 1-Disagree, 2-Neither agree nor disagree, 3-Agree, 4-Completely Agree. Outcome measure will be reported as count of participant's responses per category. For this scale, the objective was to obtain agreeable response feedback (score of 3 or 4). The specific question to measure ease of use by clinical staff was: "The ClearSight blood pressure monitoring device meets my approval."
