Background: The ultrasound in the ICU has proved to be a non invasive and economic technique that helps the approach in the diagnosis and management of the critical patient. Echocardiography permits diagnosis such as coronary syndrome, pericardial effusion or valvulopathies and brings us the possibility of monitoring the different aspects of shock, like cardiac function or volume respond. Furthermore, lung ultrasound allows us to approach the diagnosis of pneumothorax, pleural effusion, pulmonary edema, consolidation or interstitial disease. For all the abovementioned reasons, we believe intensive residents ought to train in this aspect. Objective: To evaluate the resident´s ability to determine the hemodynamic, cardiac and respiratory situation with a basic training in ultrasound. Methods: We use VSCAN and lineal transducer probe to do lung ultrasounds in five different areas in each hemithorax. First we examine the parasternal area and then we use the axillar line to divide the lateral of the hemitorax in four parts: anterosuperior, anteroinferior, posteroinferior and postero superior; we are trying to evaluate the possible presence of: pleural sliding, pleural effusion, consolidation, A or B lines, and the correlation with the clinical aspects and X-rays or TC. We use VSCAN for echocardiography and evaluating the cardiac function, to check for the presence of segmentary contractility alterations, valvulopathies and cava vein variability. We are presented with a 73-year-old patient with previous arterial hypertension, atrial fibrillation, and chronic bronchitis who is admitted in the ICU for septic shock secondary to anastomotic rupture in the postoperative of a colon disease. Thirty-two days later, he is extubated without vasoactive drugs. On the 35th day he started having respiratory problems, fever and hypotension, needing intubation and vasoactive drugs. After a subclavian access, we suspected it to be a left pneumothorax. In the X-rays, both hemithorax bases were observed with an augment of density, mostly in the right lung. A Lung ultrasound was done in the parasternal line of the right lung and we observed pleural sliding with B lines pattern. It was not present in the left lung and we were not able to do the echocardiography because of window absence. TC confirmed the presence of anterior pneumothorax, and a thorax tube was inserted. The clinical situation did not improve. ECG demonstrated a new Q wave in the septal face and negative T in the lateral face. An echocardiography was done and moderate biventricular dysfunction, left ventricle dilated with dyskinetic movement were observed. We also noticed pericardial effusion with a dubious tamponade of the right ventricle, nonetheless this was dismissed because this collapse movement occurred in systole. There were mitral and tricuspid insufficiencies. The cava vein was dilated without variability. At a later time, another lung ultrasound was done where pleural sliding was observed in both hemithorax, with a B line pattern at the parasternal line. Pleural...
