ClinConnect Summary

Backgroud: This study aims to evaluate the ability of stroke volume variation (SVV) and pulse pressure variation (PPV) to predict fluid responsiveness in mechanically ventilated participants with artificial Pneumothorax during esophageal surgery.

Methods: 40 participants, diagnosed with esophageal cancer, undergoing thoracoscopic radical resection of esophageal cancer were studied. All the participants used Vigileo/FloTrac system for analysis. Haemodynamic data such as MAP, HR, SV, SVI, CO, CI, SVV, PPV were recorded before and after volume expansion (VE). Fluid responsiveness was defined ...
