Utility of Pulmonary Echography for Evaluation of Patients Undergoing Orthopedic Surgery for Femur Fracture

"Pulmonary echography during preoperative evaluation for patients undergoing urgency orthopedic surgery for femur fracture.~Pulmonary ultrasound will evaluate the presence of one of four patterns defined by Lung Ultrasound Score in the 6 fields for each hemithorax of the patient (2 anterior, 2 lateral and 2 posterior). Each region is defined by axillary lines (anterior and posterior) and then is divided into 2 subregions (superior and inferior), thus defining the 6 fields. For a comprehensive exam, all intercostal spaces in the setting of each field will have to be examined by sliding the probe along them . A score will be used for each field that will have this definition:~* 0: normal pattern (A-lines)~* 1: multiple B lines (at least 3 for field), well defined.~* 2: B lines coalescent~* 3: consolidation of any dimension"
