Lower-extremity blood pressure monitoring during cesarean under spinal anesthesia

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective single-center observational study enrolling women undergoing elective cesarean delivery under spinal or combined spinal-epidural anesthesia. The study compares continuous hemodynamic data from upper and lower extremities using the ClearSight system to see which location more accurately predicts neonatal outcomes such as APGAR scores, need for respiratory support, cord gases, and NICU admission. Standard perioperative care is provided, with additional simultaneous monitoring at the arm and toe from before spinal anesthesia through delivery. Data will be analyzed to determine whether lower-extremity measurements improve detection of hypotension and prediction of neonatal outcomes beyond traditional arm measurements. No extra interventions beyond routine care are performed.
