At present, with the continuous development of society and increasingly busy traffic, car accidents occur from time to time, and often appear to be mainly traumatic brain injury, but also fractures, visceral injuries and other multiple injuries, the condition is often more complex. Generally, they will first actively deal with surgical problems, such as cranial surgery, visceral repair, fracture reset, etc. After surgery, due to the seriousness of the patient often live in the intensive care unit, this series of emergency treatment after the end of the patient will be in a relatively embarrassing situation, the intensive care unit that the condition is stable can be transferred out, but to which department? Transfer to surgery but there is no surgical indication, transfer to internal medicine many surgical need to monitor the part of internal medicine is not good to grasp. In fact, this time in terms of medical treatment of patients to perform hyperbaric oxygen therapy is often better, because after craniocerebral injury hyperbaric oxygen therapy can improve its microcirculation, enhance local oxygen supply to the injured tissue, reduce neuroedema and other mechanisms for the treatment of nerve damage; for other organ damage, especially like liver and spleen and other organ damage, hyperbaric oxygen can promote its repair; for the treatment of fractures has been unanimously recognized. Therefore, I believe that patients with cranio-cerebral damage caused by car accidents should be treated with hyperbaric oxygen as soon as possible after surgical treatment and the systemic status reaches a certain standard; therefore, it is most appropriate to transfer such patients to a department with a specialized hyperbaric oxygen monitoring ward.
