Background We have previously reported that dynamic preload variables predicted fluid responsiveness in adult patients with liver cirrhosis. However, pediatric patients with cirrhosis may present with unique hemodynamic characteristics, and therefore, the predictive accuracy of these variables in such patients must be clarified. Aims To investigate the accuracy of dynamic preload variables for predicting fluid responsiveness in pediatric patients with cirrhosis. Methods A total of 27 pediatric patients with cirrhosis undergoing orthotopic liver transplantation were enrolled in this study. Patients’ pulse pressure variation, stroke volume variation, stroke volume index, and central venous pressure were measured using the calibrated pulse contour cardiac output system. The plethysmographic variability index was measured using a Masimo Radical 7 co‐oximeter. During the hepatic dissection phase of the surgery, repeated intraoperative fluid challenges with 10 mL kg−1 of crystalloid within 15 minutes were administered. Fluid responsiveness was defined as an increase in stroke volume index of ≥15% after fluid challenge. Results A total of 61 fluid challenges were administered resulting in 15 fluid responders and 46 fluid nonresponders. Fluid challenge induced significant decreases in all three dynamic preload variables but not in the fluid nonresponders. However, the area under the receiver operating characteristic curves for pulse pressure variation, stroke volume variation, plethysmographic variability index, and central venous pressure for predicting fluid responsiveness were 0.67 (95% confidence interval: 0.52‐0.82; P = .0255), 0.68 (95% confidence interval: 0.54‐0.83; P = .0140), 0.56 (95% confidence interval: 0.40‐0.71; P = .4724), and 0.57 (95% confidence interval: 0.40‐0.74; P = .4192), respectively. Conclusions Dynamic preload variables do not predict fluid responsiveness in pediatric patients with liver cirrhosis.
