Comparative Study
A prospective study of emergent abdominal sonography after blunt trauma.
In North America, the role of emergent abdominal sonography [ultrasonography (US)] after blunt trauma requires further definition. The purpose of this prospective study was to compare US to the gold standards, diagnostic peritoneal lavage (DPL), and computed tomography (CT), in a population of adults after blunt trauma. In 206 adults who required either CT or DPL to assess possible abdominal injury, US was performed, before DPL or CT, and was aimed at the detection of intraperitoneal fluid. ⋯ Of the six false-negative USs, only one required surgery. The US examinations required 2.6 +/- 1.4 min. Emergent abdominal sonography is an accurate, rapid test for the presence of intraperitoneal fluid in adult blunt trauma victims and in these patients may prove valuable as a screening test for abdominal injury.

Health care reform will affect the relationship of trauma centers to health maintenance organizations and other managed care plans. We studied Kaiser Permanente Medical Center (Kaiser) members admitted to the Trauma Center at San Francisco General Hospital (SFGH) to determine: (1) variables predicting transfer from SFGH to a Kaiser Hospital (repatriation), (2) the length of hospital stay (LOS), and (3) the cost of their care. The SFGH trauma registry provided data on 7,794 patients admitted before 1994. ⋯ A relatively small number of severely injured patients account for a large percentage of costly trauma care. Analyses of patient subsets are necessary for trauma centers to negotiate suitable relationships with managed care plans. A prospective study is needed to examine the cost efficiency of early transfer of managed care patients.

Comparative Study
Cultured epithelial autograft: five years of clinical experience with twenty-eight patients.
Cultured epithelial autograft (CEA) has been used as an adjunct in burn wound coverage at the Vancouver Hospital and Health Sciences Centre since 1988, and has been available to all patients admitted with significant burn injuries. During the 5-year period from 1988 to 1992 inclusive, 28 patients treated with CEA survived long enough for assessment. The mean age was 35.3 years with a mean total body surface area burn of 52.2% and a mean total full thickness injury of 42.4%. ⋯ The anterior trunk and thighs were the best recipient sites. Subjective differences between CEA and meshed autograft were noted. The results show that after 5 years of use, CEA engraftment continues to be unpredictable and inconsistent, and hence, it should be used as only a biologic dressing and experimental adjunct to conventional burn wound coverage with split thickness autograft.

Comparative Study
Outcome from critical care in the "oldest old" trauma patients.
This study evaluated the "oldest old" Intensive Care Unit (ICU) trauma patients, defined as patients of age 75 and over, to determine the relationships between age, injury magnitude, physiologic severity of illness, and outcome in this group, compared with younger trauma patients. Of 1,039 consecutive Surgical ICU (SICU) patients with complete data, 45 were in the Oldest group, 54 were in the Elderly group (ages 65 to 74), and 940 were in the Younger group (age < 65). Age, sex, and type of trauma (penetrating versus blunt) did not predict outcome. ⋯ When patients were stratified by ISS, there was a statistically significant difference in day 1 SAPS among age groups for most ISS categories, with higher SAPS associated with advancing age. The oldest old fare worse with trauma because their injury is more severe (higher ISS) and because their physiologic response to a given level of injury is exaggerated (higher SAPS). However, once the oldest old are stratified by SAPS, their outcome parallels that of their younger trauma cohorts.(ABSTRACT TRUNCATED AT 250 WORDS)

The purpose of this study was to determine the frequency and significance of computed tomographic (CT) scan-detected pneumoperitoneum in blunt abdominal trauma. We retrospectively reviewed 118 consecutive CT scans of the abdomen in blunt abdominal trauma patients (mean Injury Severity Score 24), performed at our Regional Trauma Unit over a 12-month period. Seven (5.9%) patients had intra-abdominal extraluminal air. ⋯ In the setting of blunt abdominal trauma pneumoperitoneum does not necessarily indicate hollow viscus injury. It frequently is secondary to other etiologies, especially dissection of interstitial air from the chest, as suggested in this study. The decision for laparotomy should be based on a combination of the clinical findings, CT scan results, or other diagnostic tests such as peritoneal lavage.
