毒理性
保持呼吸道通畅,必要时协助通气。积极使用静脉晶体液治疗由出血性胃肠炎引起的休克,并在需要时输血。由于胃肠道丢失和液体进入肠壁和间质空间的第三间隙,患者常常出现明显的低血容量。如果出现昏迷、癫痫和代谢性酸中毒,则进行治疗。对于严重中毒受害者(例如,休克、严重酸中毒和/或血清铁> 500-600 mcg/dL),给予去铁胺。监测尿液,以发现特征性的橙色或粉红色去铁胺-铁复合物。当尿液恢复正常或血清铁水平降至正常范围时,可以停止治疗。长期使用去铁胺与成人呼吸窘迫综合征和耶尔森菌血症有关。
Maintain an open airway and assist ventilation if necessary. Treat shock caused by hemorrhagic gastrointestinitis aggressively with intravenous crystalloid fluids, and replace blood if needed. Patients are often markedly hypovolemic owing to gastrointestinal losses and third spacing of fluids into the intestinal wall and interstitial space. Treat coma, seizures, and metabolic acidosis if they occur. For seriously intoxicated victims (eg, shock, severe acidosis, and/or serum iron > 500-600 mcg/dL) administer deferoxamine. Monitor the urine for the urine for the characteristic orange or pink deferoxamine-iron complex. Therapy may be stopped when the urine returns to normal or when the serum iron level decreases to the normal range. Prolonged deferoxamine has been associated with adult respiratory distress syndrome and Yersinia sepsis.
