Early Heart Rate Variability and Sleep and Quality of Recovery After Cesarean Delivery

Sponsor: Buca Seyfi Demirsoy State Hospital

Summary

This prospective single-center observational cohort study investigates whether objectively measured early postoperative heart rate variability (HRV) and sleep parameters are associated with patient-reported quality of recovery after cesarean delivery. Women who deliver by cesarean section wear a consumer wrist device (Garmin Vívosmart 5) on the non-dominant wrist during the in-hospital period (first 48 hours). HRV metrics (e.g., RMSSD), continuous heart rate, and sleep are derived from raw beat-to-beat intervals via the Fitrockr platform. Quality of recovery is measured with the validated Turkish Obstetric Quality-of-Recovery score (ObsQoR-11T) at 24 and 48 hours, and subjective sleep with the Richards-Campbell Sleep Questionnaire (RCSQ). The primary hypothesis is that higher early HRV (particularly RMSSD) and better sleep are associated with higher ObsQoR-11T at postoperative day 1 (24 hours). The wearable is used for research purposes only and does not inform any clinical decision; routine care proceeds independently of the study.
