Why the study?

Does heart rate variability (HRV) analysis predict spinal-induced hypotension in women undergoing elective cesarean section under spinal anesthesia?

Population

Women undergoing elective cesarean section under spinal anesthesia in South Africa

Comparison

Heart rate variability (HRV) analysis vs Baseline heart rate and body mass index (BMI)

Design

Cohort

Overview

HRV should not yet guide risk stratification before cesarean; leaves open its value as a spinal hypotension predictor.

Structured PICO
