Pre-epidural Sequential Compression Devices (SCDs) to Prevent Hypotension During Labor

- Device: SCD
- Registration Number
- NCT05250960
- Lead Sponsor
- TriHealth Inc.
- Brief Summary
When hypotension is related to epidural placement, this can occur within 15-60 minutes after placement. The purpose of this study is to build upon this preliminary work and to use a randomized controlled trial to examine the effectiveness of SCDs in preventing hypotension among a larger sample of laboring women who receive an epidural analgesia. This study will use a randomized, non-blinded, controlled design with two arms:
* Arm 1: Patient will receive 1L of LR and have SCDs applied 15 minutes before epidural placement and will be removed 1 hour after epidural placement
* Arm 2: Patient will receive 1L of LR during and after epidural placement with no use of SCDs
- Detailed Description
When hypotension is related to epidural placement, this can occur within 15-60 minutes after placement. The purpose of this study is to build upon this preliminary work and to use a randomized controlled trial to examine the effectiveness of SCDs in preventing hypotension among a larger sample of laboring women who receive an epidural analgesia. This study will use a randomized, non-blinded, controlled design with two arms:
* Arm 1: Patient will receive 1liter (L) of lactated ringers (LR) and have SCDs applied 15 minutes before epidural placement and will be removed 1 hour after epidural placement
* Arm 2: Patient will receive 1L of LR during and after epidural placement with no use of SCDs Outcome variables include occurrence of maternal hypotension or Category II fetal tracings in the first hour after epidural placement.

Group Intervention Description Intervention - SCD arm SCD Patient will receive 1L of LR and have SCDs applied 15 minutes before epidural placement and will be removed 1 hour after epidural placement
- Primary Outcome Measures
Name Time Method Hypotension 1 hour SBP \<90mmHg or an SBP decrease more than 20% from baseline (physiological measure obtained via sphygmomanometer)
Category II Tracings 1 hour Category II fetal tracings - fetal heart tracings will be reviewed by two independent nurses who will document whether Category II tracings are present or not
Category II tracings - The classification of Category II tracings includes the following:
bradycardia with variability, tachycardia, minimal variability, no variability with no recurrent decelerations, marked variability, absence of induced accelerations even after fetal stimulation, recurrent variable decelerations with minimal or moderate baseline variability, prolonged decelerations lasting more than two minutes, but less than ten minutes, recurrent late decelerations with moderate variability, variable decelerations with other characteristics such as slow return to baseline, overshooting the baseline, or 'shoulders'
