directly to a trauma center. In-hospital Management of those with trauma often requires the help of many healthcare specialists including physicians, nurses, respiratory therapists, and social workers. Cooperation allows many actions to be completed at once. Generally, the first step of managing trauma is to perform a primary survey that evaluates a person's airway, breathing, circulation, and neurologic status. These steps may happen simultaneously or depend on the most pressing concern such as a tension pneumothorax or major arterial bleed. The primary survey generally includes assessment of the cervical spine, though clearing it is often not possible until after imaging, or the person has improved. After immediate life threats are controlled, a person is either moved into an operating room for immediate surgical correction of the injuries, or a secondary survey is performed that is a more detailed head-to-toe assessment of the person. Indications for intubation include airway obstruction, inability to protect the airway, and respiratory failure. Examples of these indications include penetrating neck trauma, expanding neck hematoma, and being unconscious. In general, the method of intubation used is rapid sequence intubation followed by ventilation, though intubating in shock due to bleeding can lead to arrest, and should be done after some resuscitation whenever possible. Trauma resuscitation includes control of active bleeding. When a person is first brought in, vital signs are checked, an ECG is performed, and, if needed, vascular access is obtained. Other tests should be performed to get a baseline measurement of their current blood chemistry, such as an arterial blood gas or thromboelastography. In those with cardiac arrest due to trauma chest compressions are considered futile, but still recommended. Correcting the underlying cause such as a pneumothorax or pericardial tamponade, if present, may help. A FAST exam may help assess for internal bleeding. In certain traumas, such as maxillofacial trauma, it may be beneficial to have a highly trained health care provider available to maintain airway, breathing, and circulation. Intravenous fluids Traditionally, high-volume intravenous fluids were given to people who had poor perfusion due to trauma. This is still appropriate in cases with isolated extremity trauma, thermal trauma, or head injuries. In general, however, giving lots of fluids appears to increase the risk of death. Current evidence supports limiting the use of fluids for penetrating thorax and abdominal injuries, allowing mild hypotension to persist. Targets include a mean arterial pressure of 60 mmHg, a systolic blood
