The nutritional needs of critically ill septic patients or patients with multiple injuries are often difficult to estimate. Indirect calorimetry can simply and accurately determine individual caloric and nutritional needs, especially in cases of critically ill patients with complicated injuries. This prospective study compared the measured energy expenditures of 30 patients using indirect calorimetry with their predicted basal energy expenditure according to the Harris-Benedict equation, or their calculated energy expenditure derived from basal energy expenditure times, an activity factor, and a stress factor. ⋯ Their stress factors could be modified as "0.97 + 0.0125 x SSS" to get a more accurate Harris-Benedict calculation. For the 15 patients with multiple injuries in whom the measured energy expenditure per kilogram was 34.9 +/- 1.6 kcal/kg, the ISS offered the best correlation with measured energy expenditure per kilogram (r = 0.84, Y = -31.47 +/- 1.73 X). Their stress factors could be modified as "1.04 + 0.0077 x ISS" to get a more accurate Harris-Benedict calculation.

As triage and resuscitation protocols evolve, it is critical to determine the major extracranial variables influencing outcome in the setting of severe head injury. We prospectively studied the outcome from severe head injury (GCS score < or = 8) in 717 cases in the Traumatic Coma Data Bank. We investigated the impact on outcome of hypotension (SBP < 90 mm Hg) and hypoxia (Pao2 < or = 60 mm Hg or apnea or cyanosis in the field) as secondary brain insults, occurring from injury through resuscitation. ⋯ Hypoxia and hypotension are common and detrimental secondary brain insults. Hypotension, particularly, is a major determinant of outcome from severe head injury. Resuscitation protocols for brain injured patients should assiduously avoid hypovolemic shock on an absolute basis.

Fractures of the clavicle and scapula are usually treated conservatively. After malunion functional results are usually good, however, function and shoulder contour can be improved by corrective osteotomies.

Physicians, fearful of an increase in the incidence of intubation mishaps (IMs) and pulmonary complications (PUCs), have been reluctant to use paralysis and intubation (PI) outside the OR. This study examines the correlations between PI, IM, and PUC. Since 1987, we have used PI when complex injury or combative behavior warranted. ⋯ There was no statistical relationship between IM and PUC (Fisher's exact test). However, patients with PUCs had a significantly higher AIS-chest score (2.9 +/- 1.7 vs. 0.9 +/- 1.5) (p < 0.0005, Student's t test) and ISS (27.3 +/- 9.6 vs. 14.5 +/- 10.8) (p < 0.0005, Student's t test). In our hands, PI is associated with low morbidity, no mortality, and can be safely used to facilitate injury management or to control combative behavior.

A review of 89 cases of posterior fossa epidural hematoma (PFEDH) is presented. The mortality rate was 17.9%. In 44 cases (49.4%) there were associated intracranial hematomas. ⋯ In 14 cases the PFEDH was treated at the subacute or chronic stage. All but one patient survived with a good recovery. Children generally had better prognoses.
