Shock, or acute circulatory failure, is a group of syndromes associating a sudden reduction in effective blood volume with alteration in the transport and delivery of energy substrates, resulting in a tissue oxygen "debt".Surgical, radiological or endoscopic haemostasis procedures in a patient in a state of haemorrhagic shock most often require anaesthesia.The management of a patient in a state of hemorrhagic shock is a challenge for the resuscitation anesthetist. It requires the choice of a simple anesthetic technique and the use of elaborate resuscitation methods, all of which are aimed at reducing the mortality of patients, often young patients in traumatology and gynecology-obstetrics
