Peripheral nerve stimulator-induced electrostimulation at the P6 point reduces the incidence of post-spinal hypotension in patients undergoing post-trauma orthopaedic surgery

Abstract

Objectives: Sympathetic block following spinal anaesthesia is often associated with a fall in blood pressure. This fall has been shown to be attenuated by using transcutaneous nerve stimulation at the P6 point in patients receiving spinal anaesthesia for Caesarean section. The aim of this study was to evaluate the efficacy of stimulation at the P6 point, using peripheral nerve stimulator (PNS), for the prevention of a fall in blood pressure in trauma patients undergoing surgery under spinal anaesthesia.
