Does general anesthesia alter autonomic cardiac indices in children under 8 years old?
General anesthesia causes a transient decrease in autonomic cardiac regulation in children under 8, which normalizes within 12 hours post-surgery.
Venet et al. (2018) conducted an observational in Scheduled surgery requiring general anesthesia (n=44). General anesthesia vs. Baseline before surgery was evaluated on Variations in autonomic cardiac indices (heart rate variability). General anesthesia in children under 8 years old caused a dramatic decrease in heart rate variability indices that normalized to baseline thresholds within 12 hours after surgery.
