The Effect of Preoperative Anxiety on Duration and Efficacy of Motor and Sensory Block in Spinal Anesthesia

The Effect of Preoperative Anxiety on Duration and Efficacy of Motor and Sensory Block in Spinal Anesthesia

Spinal anaesthesia results in blockade of sympathetic efferent neurones. Patients with higher baseline sympathetic activation have been shown to have more marked hypotension after spinal anaesthesia. Anxiety causes generalized sympathetic activation. It was aimed to find the effect of preoperative anxiety on the duration and efficacy of neuraxial anaesthesia.
