Abstrakt:	To explore the value of ultrasound in volume assessment during the perioperative period of single-shot spinal anesthesia for total hip arthroplasty. A total of 100 patients undergoing elective surgery under spinal anesthesia at our hospital from January 2022 to January 2024 were selected. Transthoracic echocardiography was used to measure the diameter of the abdominal aorta (Ao) before anesthesia (T1), 10 minutes after anesthesia (T2), and 30 minutes after anesthesia (T3). The inferior vena cava collapsibility index (IVC-CI) and the ratio of IVCe to Ao (IVCe/Ao) were calculated. A volume load test was performed 10 minutes after anesthesia. Based on the increase in stroke volume (ΔSV) after the volume load test, patients were divided into a volume-responsive group (ΔSV ≥ 15%) and a volume-nonresponsive group (ΔSV < 15%). The reliability of inferior vena cava parameters in predicting hypotension after spinal anesthesia and the value in predicting volume responsiveness postanesthesia were evaluated using ROC curves. A total of 100 patients were enrolled, 18 were withdrawn, and a total of 82 patients were included. After the volume load test, the parameters of the volume response group and the volume nonresponse group were basically consistent, and the difference was not statistically significant (P > .05). The SV of volume reaction group was significantly higher than that of volume no reaction group (P < .05). The incidence of hypotension in the volume response group was higher than that in the non-volume response group (51.28% vs 11.63%, χ2 = 15.174, P < .01). The AUC for volume reactivity prediction using IVCe, IVCi, IVC-CI, and IVCe/Ao were 0.62, 0.71, 0.70, and 0.72, respectively. IVCi, IVC-CI, and IVCe/Ao were significant predictors of volume reactivity (P < .05). The AUC predicting persistent hypotension after spinal anesthesia using IVCe, IVCi, IVC-CI, and IVCe/Ao were 0.78, 0.79, 0.70, and 0.84, respectively. IVCe, IVCi, IVC-CI, and IVCe/Ao can predict volume reactivity before anesthesia. IVCi, IVC-CI, and IVCe/Ao predicted persistent hypotension in patients with spinal anesthesia after anesthesia, and IVCe/Ao showed the best predictive effect. Thus, IVCe/Ao is a reliable parameter for predicting persistent hypotension and assessing volumetric reactivity.
