Thoracic Ultrasound on Upper Gastrointestinal Bleeding (ECOBLEDSTUDY)

Upper Gastrointestinal bleeding (UGIB) is a medical emergency and the most common cause of hospitalization associated with digestive disease. Proper initial resuscitation is the first step in the management of UGIB patients. Today, modern pulmonary ultrasound is used in different clinical settings, such as intensive care, emergency medicine and/or traumatology. In the last years, the use of this has been standardized both in internal medicine and in pulmonary medicine. The primary objective is to describe the findings of pulmonary ultrasound and its relationship with severity in patients with UGIB. The investigators will include all patients with UGIB. A pulmonary and vena cava ultrasound will be performed on admission to the emergency room, 10 minutes prior to endoscopy and 24 hours after having performed the endoscopy. The use of thoracic point-of-care ultrasound (TPOCUS) has been standardized in both internal and pulmonary medicine. There is a concern about the role of TPOCUS useful as a severity prognostic tool in patients with UGIB. The team proposes that TPOCUS is a severity prognostic tool in UGIB patients. Main Outcome: To describe the findings of TPOCUS in patients with variceal and non-variceal UGIB. Secondary Objectives: 1. Correlate the presence of B-type lines on TPOCUS with mean arterial pressure in UGIB patients. 2. Correlate the inferior vena cava diameter with the Model for End-stage Liver Disease scale in UGIB patients. 3. Correlate the inferior vena cava diameter with the 48 hours post-admission mortality of UGIB patients. Authors design a prospective, longitudinal, descriptive study to identify the findings of TPOCUS in patients with variceal and non-variceal UGIB. Patients will be included in the study since May 15th through October 30th 2019, admitted to the University Hospital, "Dr. José E. González", Universidad Autónoma de Nuevo León.
