There are also special considerations to take into effect as given the nature of injuries, there is a higher likelihood that persons with these injuries might be under the influence of illicit substances which can make it harder to obtain a complete medical history. Special precautions should also be taken to prevent further injury from a perpetrator to the victim in a hospital setting. Similarly to treating shock, it is important to keep the systolic pressure above 90mmHg, maintain the persons core body temperature, and for prompt transport to a trauma center in severe cases.To determine if internal bleeding is present a focused assessment with sonography (FAST) or diagnostic peritoneal lavage (DPL) can be used. Other diagnostic tests such as a computed tomography scan or various contrast studies can be used to more definitively classify the injury in both severity and location. Local wound exploration is also another technique that may be utilized to determine how far the object penetrated. Observation can be used in place of surgery as it can substitute an unnecessary surgery, which makes it the preferred treatment of penetrating trauma secondary to a stab wound when hypovolemia or shock is not present. Laboratory diagnostic studies such as a hematocrit, white blood cell count and chemical tests such as liver function tests can also help to determine the efficiency of care. Surgery
Surgical intervention may be required but it depends on what organ systems are affected by the wound and the extent of the damage.
A laryngocele is a congenital anomalous air sac communicating with the cavity of the larynx, which may bulge outward on the neck.It may also be acquired, as seen in glassblowers, due to continual forced expiration producing increased pressures in the larynx which leads to dilatation of the laryngeal ventricle (sinus of Morgagni). It is also seen in people with chronic obstructive airway disease. Additional images
