Detection of cervical spine injuries in alert, asymptomatic geriatric blunt trauma patients: who benefits from radiologic imaging?
There are differing recommendations in the literature regarding cervical spine imaging in alert, asymptomatic geriatric patients. Previous studies also have not used computed tomography routinely. Given that cervical radiographs may miss up to 60 per cent of fractures, the incidence of cervical spine injuries in this population and its implications for clinical management are unclear. ⋯ The overall incidence of cervical spine injury in the alert, asymptomatic geriatric population is low. The risk is increased with a potentially distracting injury above the clavicles. Patients with distracting injuries in other anatomic locations or no distracting injuries may not need routine cervical imaging.

Effects of sentinel lymph node biopsy on surgical residency training.
Axillary node dissection (AND) is an integral part of surgical training. Sentinel lymph node biopsy (SLN) was introduced into our residency in 1997. Our purpose in this study was to evaluate the impact of SLN on AND experience. ⋯ Attendings cited 15 and 24 AND before feeling comfortable performing and teaching the procedure to a resident. Since the introduction of SLN into our residency, the number of AND has decreased, with senior residents feeling that SLN has decreased their ability to perform AND. As fewer AND are performed than our attendings cite to feel comfortable, future residents may not be competent to perform or teach AND.

Since 1996, the technique for minimally invasive repair of pectus excavatum (MIRPE) has gained increasing acceptance among pediatric patients. However, the feasibility of the operation and outcomes have not yet been evaluated in adult patients. This study was a retrospective analysis of the author's experience combined with a survey of members of the American Pediatric Surgical Association in treating adult patients with MIRPE. ⋯ MIRPE can be used safely for repair of pectus excavatum in adult patients. The complication rate appears to be similar to previously reported series of pediatric patients. Although adult patients may have residual asymmetry of the chest postrepair, overall satisfaction with the repair was very good or excellent in 86 per cent of patients.

Multicenter Study Comparative StudyEvaluation of the effect of endovascular options on infrarenal abdominal aortic aneurysm repair.
Endovascular devices designed to exclude flow to infrarenal abdominal aortic aneurysms (AAA) were approved by the Food and Drug Administration in the United States in 1999. This action allowed widespread use of this technology for AAA exclusion. The purpose of this report is to examine trends for use of these modalities, rates of rupture of AAA, and to compare results of open AAA repair with endovascular repair. ⋯ Mortality from endovascular AAA repair between 2001 and 2002 was 1.9 per cent (P = 0.003). Major morbidity was 14.5 per cent for open, elective AAA repair and 6.3 per cent for endovascular elective repair from 2001 to 2002 (P < 0.001). These data suggest that the advent of endovascular AAA repair has contributed to a reduction in the rate of ruptured AAA repairs, an increase in total procedures performed, and a significant decrease in perioperative deaths and major complications when compared with open AAA repair.

Randomized Controlled TrialImpedance cardiography: can it replace thermodilution and the pulmonary artery catheter?
Clinical assessment of cardiac output (CO) is inaccurate, yet the use of the pulmonary artery catheter (PAC) for thermodilution (TD) measurement of CO (CO(TD)) has declined significantly. Can noninvasive impedance cardiography (ICG) now be used to measure CO (CO(ICG)) in place of CO(TD)? A literature review of recent CO(ICG) correlations with CO(TD) (r = 0.73-0.92) were similar to ours, r = 0.81. A search for conditions interfering with CO(ICG) revealed no serious problems with patient position, cardiac or pulmonary assist devices, "wet lungs," body mass index > or = 30, or age > or = 70 years. ⋯ Data from ICG was revealed only in the study group, resulting in a 49 per cent change in treatment compared with 29 per cent in the control group. Length of stay was shorter in the study than the control group in the intensive care unit (2.4 +/- 8.8 vs 3.3 +/- 7.3 days) and on the floor (9.8 +/- 10.6 vs 15.7 +/- 19.0 days). In conclusion, ICG is comparable with TD, is easily, accurately, and safely performed, enhances clinical assessment of CO, and improves care in hemodynamically compromised patients.
