Hypotension Prediction Index to Predict Epidural-labor Analgesia Induced Hypotension
- Conditions
- HypotensionAnesthesia, Epidural
- Interventions
- Diagnostic Test: ClearSight HPI Monitoring systemDiagnostic Test: Standard of Care Blood Pressure Monitoring
- Registration Number
- NCT05906368
- Lead Sponsor
- Grace Lim, MD, MS
- 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.

Group Intervention Description ClearSight Monitoring ClearSight HPI Monitoring system Patients are wearing both a conventional blood pressure cuff and the ClearSight finger cuff blood pressure monitoring system. Measures from BOTH the conventional blood pressure cuff and ClearSight monitoring system are sent/received by the clinical staff in the central and local nursing and anesthesia staff areas. ClearSight monitoring will add additional information regarding hypotensive events for clinical staff to respond to. Conventional Care Standard of Care Blood Pressure Monitoring Patients are wearing both a conventional blood pressure cuff and the ClearSight finger cuff blood pressure monitoring system. Only measures from the conventional blood pressure cuff are sent/received by the clinical staff in the central and local nursing and anesthesia staff areas. The ClearSight monitoring system data is collected but not used by the clinical staff team for hypotensive monitoring. ClearSight Monitoring Standard of Care Blood Pressure Monitoring Patients are wearing both a conventional blood pressure cuff and the ClearSight finger cuff blood pressure monitoring system. Measures from BOTH the conventional blood pressure cuff and ClearSight monitoring system are sent/received by the clinical staff in the central and local nursing and anesthesia staff areas. ClearSight monitoring will add additional information regarding hypotensive events for clinical staff to respond to.
- Primary Outcome Measures
Name Time Method Time-to-treatment of hypotension (minutes) 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
Satisfaction of ClearSight use by clinical staff report at 4-hour post-infusion Clinical nurse reports of satisfaction of use of ClearSight device (likert scale 0 - 5)
Ease of use by clinical staff report at 4-hour post-infusion Clinical nurse reports of ease of use of ClearSight device (likert scale 0 - 5)
Ease of hypotension detection by clinical staff report at 4-hour post-infusion Clinical nurse reports of ease of hypotension detection using ClearSight device (likert scale 0 - 5)
- Secondary Outcome Measures
Name Time Method Total phenylephrine, mg Epidural placement to 4-hours post-infusion start Average phenylephrine dose(s) given to patients in CM and CM+HPI groups
Total number of reported changes in fetal heart rate category (from healthy to deceleration or excelleration) Epidural placement to 4-hours post-infusion start Average number of Fetal heart rate decelerations noted within the CM and CM+HPI groups.
Vomiting (Yes/No) Epidural placement to 4-hours post-infusion start Proportion of patients by group reporting Vomiting within 4-hours of post-epidural placement
Total time in hypotension with mean arterial pressure (MAP) <65 mmHg (in minutes) Epidural placement to 4-hours post-infusion start Average number of minutes patients spent within hypotensive events for each group (CM and CM + HPI).
Nausea (Yes/No) Epidural placement to 4-hours post-infusion start Proportion of patients by group reporting nausea within 4-hours of post-epidural placement
Total ephedrine, mg Epidural placement to 4-hours post-infusion start Average ephedrine dose(s) given to patients in CM and CM+HPI groups
Total intravenous fluids, mL Epidural placement to 4-hours post-infusion start Average volume of fluids given to patients in CM and CM+HPI groups
Fetal heart rate decelerations within 1 hour of initiation of ELA Epidural placement to 1-hour post-infusion start Proportion of patients who experience any fetal heart rate deceleration event \[Presence (Yes) or absence (No)\] within 1-hour of epidural placement.
