Description
An account of the resource
BACKGROUND: Traumatic brain injury (TBI) is a leading cause of morbidity and mortality in trauma patients. Cerebral perfusion pressure (CPP) directed ICU management is recommended for patients with severe TBI. It, however, requires an invasive device to measure intracranial pressure (ICP). Transcranial cerebral oximetry is a noninvasive method utilizing near-infrared technology to indirectly measure cerebral saturation (StCO2). METHODS: A prospective observational study was performed at a Level I trauma center. Data were collected hourly for the first 6 days on four patients with severe TBI. Each patient had ICP monitoring and StCO2 (INVOS, Somanetics) assessed from each frontal lobe. CPP directed care was used. RESULTS: Four patients with TBI, with admission GCS scores of 4, 4, 7, and 8, all had subdural hematomas and contusions; three had subarachnoid hemorrhage (SAH); one had an epidural hematoma (the only death; day 6); two had craniotomies. In the first 48 hours when CPP \textgreater or = 70, StCO2 was 71 +/- 9, while it was 61 +/- 9 when CPP \textless 70 (p \textless 0.0001). This relationship was constant for all study days, with p \textless 0.0001. Moreover, CPP \textless 70 correlated with StCO2 with r = 0.8l and r(2) = 0.66. StCO2 \textgreater or = 75 was associated with CPP \textgreater or = 70 96.4% of the time (95% CL, 94.3-98.5%). StCO2 \textless 55 was associated with CPP \textless 70 68.2% of the time (95% CL, 57-79.4%). Also, 13.4% of observations with CPP \textgreater or = 70 had StCO2 \textless 60, suggesting the potential of cerebral ischemia in the face of 'normal' CPP. The StCO2 patches were user-friendly and not technically finicky. CONCLUSION: In this pilot study, StCO2 correlated significantly with CPP. A StCO2 \textgreater or = 75 suggests that CPP is adequate, while \textless 55 suggests an inadequate CPP. Although these results should be confirmed in a larger study, StCO2 may serve as a noninvasive measurement of cerebral perfusion in the patient with a TBI or, at the very least, a sensitive indicator for the need to begin monitoring the ICP.

BACKGROUND: The parameters of self-tapping screw (STS) performance in normal and osteoporotic bone have been defined in representative environments, but the question remains as to the clinical application of such findings. The goal of this study was to analyze the biomechanical performance of STSs in cadaveric and synthetic environments representative of healthy and osteoporotic bone. METHODS: Ninety-six Synthes STSs were inserted into cadaveric and synthetic models representative of osteoporotic and healthy bone. Screws were inserted to depths of 1 mm short of the far cortex, flush and 1 mm and 2 mm beyond the far cortex. Screws were tested with an Instron 8511 material testing system utilizing axial pullout forces. A SAS procedure was used to conduct analysis of variance for unbalanced datasets. RESULTS: Substantial differences were appreciated with respect to screw performance between osteoporotic and healthy bone specimens. Although a similar pattern of increased pullout strength and loading energy with increasing depth of insertion was demonstrated, absolute values were lower in osteoporotic specimens. Although performance trends were similar in cadaveric and synthetic testing models for both osteoporotic and healthy bone, values obtained during testing were different. Incomplete insertion of STSs resulted in a 21.5% and 37% reduction of biomechanical properties in osteoporotic and normal bone, respectively. CONCLUSIONS: These results indicate that previously published findings on the performance of STSs in synthetic models cannot reasonably be applied to the clinical realm. Although trends may be similar, screw performance in synthetic, as compared with cadaveric, models is markedly different.

Description
An account of the resource
BACKGROUND:: The purpose of this study was to determine whether trauma patients who are intubated because of combativeness, and not because of medical necessity, have more complications resulting in longer lengths of stay. METHODS:: Data were retrospectively collected from 2001 through 2004 on trauma patients who were intubated because of combative behavior before hospital admission (group 1, N = 34). Cases were matched 1:2 by age, sex, injury severity score (ISS), and injury to controls each who were not intubated (group 2, N = 68). Additionally, there were 187 patients identified who were intubated because of medical necessity before hospital admission; these represented unmatched intubated controls and were divided based on ISS \textless15 (group 3, N = 58) and ISS \textgreater15 (group 4, N = 129). RESULTS:: There were no significant differences between groups 1, 2, and 3 with regard to age, sex, or ISS. There was no significant difference between the groups 1 and 2 in frequency of head injuries as demonstrated by positive computed tomography (50 vs. 37%, p = 0.28); however, there was a significant difference in frequency of neurologic deficit at discharge (33 vs. 6%, p = 0.006). There was a significant difference in the frequency of head injuries between groups 1 and 3 (50 vs. 22%, p = 0.006); however, there was no significant difference in neurologic deficit at discharge (33 vs. 22%, p = 0.24). There was a significant difference in hospital length of stay between groups 1 and 2 (7.4 +/- 5.9 vs. 4.3 +/- 4.5 days, p = 0.0009). The incidence of pneumonia was significantly greater in group 1 than in group 2 (29 vs. 0%, p \textless 0.0001). The amount of lorazepam in average mg per day was also significantly greater in group 1 versus group 2 (4.4 +/- 11.5 vs. 0.4 +/- 1.6, p \textless 0.0001). There was also a difference in the discharge status, with significantly fewer group 1 cases being discharged home compared with group 2 (56 vs. 91%, p \textless 0.0001). There was no significant difference between groups 1 and 3 with regard to length of stay, ventilator days, pneumonia, or discharge status. There was a significant difference between groups 1 and 3 in the amount of lorazepam per day (4.4 +/- 11.5 vs. 0.4 +/- 1.6, p = 0.002). CONCLUSION:: The results from this study indicate that trauma patients who are intubated because of combativeness, and not because of medical necessity, have longer lengths of stay, increased incidence of pneumonia, and poorer discharge status when compared with matched controls. The outcomes of this group are similar to that of patients who are intubated because of medical necessity.
