Ultrasound US is a useful tool to manage severely injured soldiers during air transport. The best metric to predict volume responsiveness VR is unknown. The most studied measure is respiratory variation in the inferior vena cava, but its accuracy in patients who have had torso surgery is unclear. This was a prospective observational study comparing several US measures in the prediction of VR in critically ill trauma and surgical patients. Over a 3-year period, 202 patients completed the study 68 were mechanically ventilated and 46 had undergone torso surgery. Respiratory variation in the inferior vena cava was not found to be associated with VR however, several other metrics including the velocity time integral and respiratory variation in the internal jugular 90 were significantly associated p0.05.
