Autonomic Nervous System Imbalance
Effects of Propofol Induction Anaesthesia on the Heart Rate Variability
The ANS plays an important role in the regulation of hemodynamics during anesthesia. Manually blous of propofol during induction anesthesia is reported to reduce both sympathetic and parasympathetic tone; however, it is not clear…
