Background
inferior vena cava, hypotension
Most cesarean deliveries are performed under spinal anesthesia. However, spinal anesthesia is responsible for a 70% incidence of hypotension [Ultrasonography of the inferior vena cava (IVC) in spontaneously breathing patients is recommended as a non-invasive method for estimating the volume status [We hypothesized that compared with empirical fluid therapy, SCVCI-guided volume optimization could prevent hypotension after spinal anesthesia in parturients undergoing cesarean delivery. Accordingly, we evaluated the efficacy of SCV ultrasound-guided volume optimization in preventing hypotension after spinal anesthesia during cesarean delivery.
