Identifying patients at risk for intracranial and extracranial blunt carotid injuries

BACKGROUND: Blunt carotid injuries are rare, often occult, and potentially devastating. Angiographic screening programs have detected this injury in up to 1% of blunt trauma patients. Implementing a liberal angiographic screening program at our hospital is impractical and we want to identify a high-risk group to target for screening. We hypothesize that intracranial and extracranial carotid injuries have different risks, presentations, and outcomes. METHODS: Patients with intracranial and extracranial carotid injuries were identified from the British Columbia trauma registry. Presentation and outcome were reviewed. To facilitate statistical modeling the analysis was done by matching cases to 5 randomly selected controls. Risk factors for injury were evaluated by univariate and multiple logistic regression. RESULTS: A total of 35 carotid injuries were identified. Thirteen intracranial injuries were identified in 10 patients. Twenty-two extracranial injuries were identified in 18 patients. Sixty-seven percent of patients with intracranial injuries and 31% of those with extracranial injuries died (P = 0.11). Eleven percent of intracranial injuries and 56% of extracranial injuries were occult (P = 0.04). Glasgow outcome scores were 2.04 intracranial and 3.12 extracranial (P = 0.18). For intracranial injuries the multiple variable predictive model had two predictors: Glasgow Coma Score or =3). CONCLUSIONS: Intracranial injuries were frequently detected on initial investigations and have very poor outcomes. Extracranial injuries were more frequently occult and stand to benefit from early detection by screening programs. As independent risk factors for these two injuries differ, limited screening resources should focus on risk factors for occult extracranial injury: namely, low GCS and significant thoracic injury.     

Variability of pressure at the pressure garment-scar interface in children after burn: A pilot longitudinal cohort study

Background

Current consensus for the ideal pressure range at the pressure garment to scar interface is 15–25 mmHg. Interface pressure variability has been reported at new pressure garment fitting in children. Pressure reductions up to 25% have been recorded over one month in adults.

Geriatric trauma: resource use and patient outcomes.

INTRODUCTION: Elderly patients who suffer trauma have a higher mortality and use disproportionately more trauma resources than younger patients. To compare these 2 groups and determine the outcomes and characteristics of elderly patients, we reviewed patients in these 2 groups admitted and treated in our tertiary care provincial trauma centre. METHODS: From the provincial trauma registry we selected a cohort of 40 geriatric patients (group 1) (> or = 65 yr of age) with an ISS of 16 or more who were admitted to and spent time in our trauma service for more than 48 hours and compared them with a similar randomly selected cohort of 44 patients (group 2) aged 20-30 years. Family physicians were contacted for follow-up of these patients 2 years after discharge. We considered length of hospital stay, complications, disposition of the patients and use of consultation services. RESULTS: Patients in group 1 had a mean age of 72.1 years (range from 65-98 yr) and a mean ISS of 27.3 (range from 17-50). Patients in group 2 had a mean age of 26.3 years (range from 22-29 yr) and a mean ISS of 26.3 (range from 17-54). Hospital stay was significantly longer in the group 1: 34.5 days (95% confidence interval [CI]: 24-44 d) versus 21.6 days (95% CI: 15-28 d). More elderly patients experienced complications (35 v. 13, p < 0.001) and required medical consultations (35 v. 26, p < 0.001). In-hospital death rates were 8% (3 of 40) and 4% (2 of 44) respectively (p = 0.3). Fewer geriatric patients could be discharged home (35% [14 of 40] v. 27% [22 of 44], p = 0.056) or to rehabilitation facilities (28% [11 of 40] v. 34% [15 of 44], p = 0.3). Five geriatric patients were discharged to nursing homes (p = 0.007). Of the geriatric patients discharged to rehabilitation facilities or home, 75% were independent 2 years after discharge. CONCLUSIONS: Aggressive care for geriatric trauma patients is warranted, and resources should be directed toward rehabilitation. Based on our findings, we expect that creating a directed care pathway for these patients, targetting complications and earlier discharge, will further improve their outcomes.
