Case ReportsUnwillingness to lie supine? a sign of pericardial tamponade.
The stable patient with an occult cardiac injury can represent a diagnostic dilemma. The trauma surgeon must maintain a high index of suspicion for cardiac injury with precordial penetrating trauma. Herein are reported two cases of stable patients with penetrating precordial trauma who refused to lie supine because of difficulty breathing, preferring to sit upright, who eventually had positive pericardial windows and sternotomies for repair of cardiac injuries. The presence of this clinical finding, unwillingness to lie supine, should make the trauma surgeon highly suspicious of a cardiac injury and to proceed quickly to echocardiography or, preferably, to subxiphoid pericardial window to rule out cardiac injury.

The effectiveness and safety of cricothyroidotomy was reviewed at our institution and in the literature. The literature review yielded nine reports on emergent cricothyroidotomy. Out of 320 patients, there were 308 successful airways and 99 survivors. ⋯ Acute complications were: misplacement or failure to obtain an airway (seven), no airway (three), chest tube required (two), and bleeding (one). In the 27 survivors long-term complications were: failure to decannulate (two), and vocal cord paralysis, granulation tissue and hoarseness, one case each. We conclude that emergent cricothyroidotomy is effective in establishing airways in emergency situations, although the survival rate is better if the patient is not in cardiac arrest (49 vs 31% in literature and 41 vs 76% in our study).

Blunt popliteal artery trauma is a challenging injury, particularly when associated with major soft tissue damage. We reviewed our experience with this injury to determine 1) the incidence of vascular injury associated with fractures and/or dislocations about the knee, 2) the incidence of limb loss, and 3) factors associated with amputation. We treated 37 patients with 38 blunt popliteal artery injuries and either fractures about the knee or posterior knee dislocations. ⋯ The overall 9 per cent rate of positive angiograms suggests that a selective approach may be indicated. The amputation rate remains high, but it has improved with an integrated, multidisciplinary team approach. In patients without a pulse or Doppler signal and with severe soft tissue injuries, primary amputation may be appropriate.

Coagulopathy in severe closed head injury: is empiric therapy warranted?
Closed head injuries account for a significant portion of the morbidity and mortality following blunt trauma. Severe closed head injuries can be complicated by the development of a coagulopathy that may worsen blood loss and delay invasive neurosurgical procedures. Awaiting the results of coagulation studies prior to initiating treatment of such a coagulopathy introduces an inherent delay that may allow worsening of the coagulation disturbance and negatively influence outcome. ⋯ We conclude that patients with closed head injuries who present with a GCS of 6 or less are candidates for empiric treatment for coagulopathy. Such treatment will negate the delay of awaiting coagulation studies. Whether or not such therapy shortens the interval between admission and neurosurgical procedures or alters outcome will require prospective study.

In patients with inferior vena cava (IVC) injuries, predictors of survival are investigated. From 1987 to 1995, 27 IVC injuries were identified among 514 patients with vascular trauma. The ability of clinical determinants to predict survival were retrospectively assessed. ⋯ Four complications [venous hypertension (n = 2), IVC thrombosis (n = 1), and pulmonary embolus (n = 1)] occurred in the 14 survivors (28.6%). Blunt injury, revised trauma score, free perforation, injury location, intraoperative hypotension, and blood loss were predictive of mortality. IVC injuries remain extremely lethal, and improved survival is associated with infrarenal penetrating injuries and a contained hematoma.
