Does heart rate variability measurement using electrical cardiometry predict hypotension following spinal anesthesia in preeclamptic parturients undergoing elective cesarean section?
Heart rate variability measured via electrical cardiometry does not reliably predict hypotension after spinal anesthesia in preeclamptic women undergoing cesarean section.
HRV by electrical cardiometry should not yet guide hypotension prediction in preeclamptic parturients; leaves open need for prospective validation.
AIM: In this study we aimed to find out the heart rate variability measuring using electrical cardiometry is not reliable as a predictor for hypotension following spinal anesthesia in preeclamptic parturients undergoing elective cesarean section. METHODS: Electrical Cardiometry system was used to measure Heart rate variability (HRV) at five different time points before fluid loading (T0, baseline), after fluid loading (T1), 5 min after spinal anaesthesia (T2), 15 min after spinal anaesthesia (T3) and 30 min after spinal anaesthesia (T4). Traditional HRV measurement was determined using time-domain analysis. This Observational descriptive cohort study was conducted in Kasr Al-Ainy Hospital, Faculty of Medicine, Cairo University from February 2018 till June 2019, after approval of the Ethical Committee and written patients consent. RESULTS: The main finding of the current study is that heart rate variability measuring using electrical cardiometry is not reliable as a predictor for hypotension following spinal anaesthesia in preeclamptic parturients undergoing elective cesarean section. CONCLUSION: Heart rate variability cannot be used as a predictor for hypotension following spinal anaesthesia in preeclamptic patients undergoing elective caesarean section using electrical cardiometry.

Shehata et al. (2019) conducted a cohort in Preeclampsia. Heart rate variability measured by electrical cardiometry was evaluated on Hypotension following spinal anesthesia. Heart rate variability measured using electrical cardiometry was not a reliable predictor for hypotension following spinal anesthesia in preeclamptic parturients undergoing elective cesarean section.
