Gastric lesions occur in most patients suffering a multiple trauma.Acute gastroduodenal lesions occurring after or during shock,sepsis, surgery, trauma, burns or in case of intracranial surgery orcranio-cerebral trauma.
Cranial and intracranial lesions can generate shock in specialsituations, such as superficial temporal artery rupture, dilacerareaa dural sinus, intracranial hematoma, or massive otoragiiepistaxisuri abundant. This phenomenon, gastro-duodenal mucosathat reacts to such traumatic events, is called "stress ulcer". Stressulcer occurs through the action of bile on gastric protective barrier,the cumulative process and decreased gastric blood flow. Gastricblood flow is reduced if the traumatic events of the body as areaction to stress by splahnica vasoconstriction via the sympathetic nervous system.
Gastric ulcer that appears in relation to cranio-cerebral traumacalled "Cushing's ulcers. " Cushing ulcer feature is that it is accompanied by gastric acid hypersecretion important.
Patients with cranio-cerebral trauma shows the gastro-duodenalerosions, but major hemorrhages are rare. Treatment ofcranio-cerebral injuries must be taken into account theneutralization of gastric acid secretion. Good results are obtainedby use of sucralfate or antacids as a hydrogen receptor blockers.Thus, the gastric pH will remain high and the action of gastric juiceand bile on the stomach lining will be diminished.
