title: [Hematemesis. Extramural emergency].
abstract: Hematemesis is the cardinal sign of upper gastrointestinal bleeding. It is a sign related to numerous affections, with a prognosis depending on the underlying lesion, the degree of bleeding, the accompanying disease and other risk factors. Mortality rates are generally close to 10%, although if hematemesis is secondary to variceal bleeding, as high as 30%. 65% of hemorrhages subside spontaneously, but 25% bleed recurrently (after initial cessation) and in 10% bleeding persists. Three quarters of all renewed bleeding occurs within two days after the initial hemorrhage. If hematemesis occurs outside a hospital, rapid evaluation is required to assess the necessity of emergency transport and treatment. In the case of severe to moderate bleeding, life-support measures and rapid transport to the nearest hospital are of primary importance and all measures complicating diagnosis and treatment in the hospital should be avoided. Patients with mild hematemesis, stable cardiovascular parameters and no risk factors can be investigated and, if appropriate, treated, on an out-patient basis. If the cause of hematemesis cannot be found, aggressive, inpatient investigations are required at the first sign of second bleed. Endoscopy is the primary investigative procedure for hematemesis. The success rate is highest if endoscopy is performed within the first 36 hours of the onset of bleeding. There are indications that aggressive diagnosis and therapy, including endoscopic hemostatic interventions, can reduce hematemesis mortality.
