Rapid evaluation of intravascular volume status is vital; either excessive or limited fluid administration may result in adverse patient outcomes. In this narrative review, critical analysis of pertinent diagnostic accuracy studies is developed to delineate the role of inferior vena cava ultrasound measurements in the assessment of both intravascular volume status and fluid responsiveness in the emergency department and intensive care unit. In addition, limitations, and technical considerations of inferior vena cava ultrasound measurements as well as directions for future research are thoroughly discussed.

Re-expansion pulmonary edema is a potentially life-threatening situation following thoracic surgery of a compromised lung. We report the case of a 24-year-old female scheduled for a resection of a large intrathoracic desmoid tumor that presented with re-expansion pulmonary edema at the conclusion of her surgery and discuss the clinical presentation, mechanism and predictors of this entity and review similar cases reported in the literature.
