Fiberoptic bronchoscopy (FB) plays an important role in making the diagnosis of nosocomial pneumonia and resolving lobar atelectasis in critically injured trauma patients. It has been shown to be a safe procedure with only occasional complications. However, in patients with head injuries, FB can lead to intracranial hypertension. Sustained increases in intracranial pressure (ICP) leads to poor outcome in these patients. Because of this, a prospective study was done not only to assess the effect of FB on ICP and cerebral perfusion pressure (CPP) in patients with brain injuries, but also to identify a regimen of sedation and anesthesia that could prevent significant increases in ICP during FB. ⋯ Although FB is an important procedure in the pulmonary care of head injured patients, it produces substantial, but transient, increases in ICP and should be used with caution in patients with diminished cranial compliance. Sedation, analgesia, paralysis, and topical tracheal anesthesia did not completely prevent the rise in ICP. Although no acute deterioration in condition occurred, secondary brain injury caused by localized cerebral ischemia is certainly possible. Because of the substantial increases in ICP, herniation may be precipitated in an occasional patient. Further study is needed to identify a regimen that will confer protection.

We evaluated outcomes 12 months after trauma in terms of general health, satisfaction, and work status. ⋯ Twelve months after trauma, patients' work status, general health, and overall satisfaction with recovery are dependent on outcome mental health. This dependency persists despite measured baseline status, ISS, or physical recovery. The mental disease after trauma is attributable to poor mental health, the development of symptoms of PTSD and depression, and increased substance abuse. Trauma centers that fail to recognize, assess, and treat these injury-related mental health outcomes are not fully assisting their patients to return to optimal function.

The evolving technology in trauma management today permits salvage of many severe lower extremity injuries previously even considered to be lethal. An essential component for any such treatment protocol must be adequate soft tissue coverage that often will use vascularized flaps. Traditionally, calf muscles have been used proximally and free flaps for the distal leg and foot. The reintroduction of reliable local fascia flaps has challenged this dictum, proving to be a simpler and yet versatile option. ⋯ The traditional role of the gastrocnemius muscles for flap coverage of knee and proximal leg defects and the soleus muscle for the middle third of the leg was reaffirmed. The soleus muscle often also reached distal leg defects as could local fascia flaps, where classically, otherwise, a free flap would have been necessary. The largest or most severe wounds, irrespective of limb location, required free flap coverage. Local fascia flaps proved to be a valuable alternative.

Comparative Study
Incidence of septic complications and multiple organ failure in severely injured patients is sex specific.
Sexual hormones are potent regulators of various immune functions. Although androgens are immunosuppressive, estrogens protect against septic challenges in animal models. This study correlates sexual dimorphism with the incidence of posttraumatic complications in severely injured patients. ⋯ Sex influences posttraumatic morbidity in severely injured patients and supports the concept that females are immunologically better positioned toward a septic challenge.

The frequency and prognostic influence of myocardial injury in patients with blunt chest trauma is controversial. We investigated the value of cardiac troponin I (cTn-I) and cardiac troponin T (cTn-T), highly specific markers of myocardial injury, to determine whether their measurement would improve the ability to detect myocardial contusion in stable patients with blunt chest trauma in comparison with conventional markers and whether they were associated with significantly worse late clinical outcome. ⋯ Although improved specificity of cTn-I and cTn-T compared with conventional markers, it should be emphasized that the main problem with cTn-I and cTn-T is low sensitivity as well as low predictive values in diagnosing myocardial contusion. cTn-I and cTn-T measurement is currently not an improved method in diagnosing blunt cardiac injury in hemodynamically stable patients. Moreover, there was no association of postmyocardial contusion cell injury and late outcome in these patients when cTn-I and cTn-T and other conventional markers were considered.
