Heart Rate Variability to Predict Hypotension Following Spinal Anesthesia in Cesarean Delivery

Seoul National University

Status: Completed

Conditions: Cesarean Section

Treatments: Other: analgesia nociception index (ANI) monitoring

Study type: Observational

Funder types: Other

Identifiers

NCT04979039

HRV Csec Spinal HypoT

Details and patient eligibility

About

Based on the patient's heart rate variability, the analgesia nociception index (ANI) measures the activity of the autonomic nervous system and the sympathetic/parasympathetic nervous system and expresses it as a numerical value through a specific algorithm. The investigators will analyze it and see if it has the ability to predict severe hypotension following spinal anesthesia.

Enrollment: 50 patients

Sex: Female

Ages: 20+ years old

Volunteers: No Healthy Volunteers
