Prospective evaluation of a critical care pathway for clearance of the cervical spine using the bolster and active range-of-motion flexion/extension techniques.

BACKGROUND: Clearance of the cervical spine after blunt trauma remains controversial in patients with normal radiologic evaluation. METHODS: Blunt trauma patients with midline boney cervical tenderness and plain films that disclose no abnormalities and computed tomography (CT) scans were entered into a care pathway for spinal clearance using the Bolster or active range-of-motion (AROM) flexion/extension techniques. The quality of films between the two techniques was then compared. RESULTS: In all, 159 patients entered the pathway with 14 patients (9%) unable to complete the examination secondary to pain. The Bolster was used in 129 patients (89%) and AROM was used in 16 (11%). The total range of motion was significantly better with AROM at 51.4 +/- 19.4 degrees of motion compared with 32.0 +/- 13.0 degrees with the Bolster (p < or = 0.05). The most distal level visualized was not different between groups with 6.6 +/- 0.8 cervical vertebrae visualized on average in the Bolster group and 6.8 +/- 0.7 in the AROM group. Positive findings occurred in five patients (3.4%) in the Bolster group. CONCLUSION: The incidence of occult cervical injury in patients with boney cervical pain despite normal plain films and CT scans in this study was 3.4%. The AROM technique has better total range of motion than the Bolster, although results of the Bolster technique remain within acceptable standards. The present care pathway appears to be an effective screening tool for evaluation of this population of patients. Additional evaluation of the obtunded patient is necessary before broad implementation of this technique.

Preliminary experience with airway pressure release ventilation in a trauma/surgical intensive care unit.

BACKGROUND: Airway pressure-release ventilation (APRV) is a pressure-limited, time-cycled mode of mechanical ventilation. The purpose of this study was to evaluate our initial experience with the use of APRV in acutely injured, ventilated patients. METHODS: Since March 2003, APRV has been used selectively in adult trauma patients with or at risk for acute lung injury/acute respiratory distress syndrome. Data were obtained before and during the 72 hours after switching to APRV. A retrospective analysis of these data was then performed. RESULTS: Complete data were available on 46 of 60 patients (77%) for the first 72 hours of APRV. Before APRV, the average Pao2/Fio2 ratio was 243 and the average peak airway pressure was 28 cm H2O. Peak airway pressure decreased 19% (p = 0.001), Pao2/Fio2 improved by 23% (p = 0.017) and release tidal volumes improved by 13% (p = 0.020) over the course of the analysis. CONCLUSION: APRV significantly improved oxygenation by alveolar recruitment and allowed for a reduction in peak airway pressures. This relatively new modality had favorable results and appears to be an effective alternative for lung recruitment in traumatically injured patients at risk for acute lung injury/acute respiratory distress syndrome.

Resident work hours: can we meet the ACGME requirements?

The Accreditation Council for Graduate Medical Education (ACGME) requires all programs to limit resident work hours to 80 hours per week with some programs allotted an extra 10 per cent for specific educational purposes. The purpose of this study was to evaluate data reflecting changes in resident schedules made in 2002-2003 to be compliant with ACGME requirements without compromising patient care or resident education. Surgery residents originally completed a work-hour survey in May 2002. The survey contained 14 daily time sheets. Residents were asked to document how their time was spent between 14 different categories delineating in-house and out-of-house hours. Changes were made to resident schedules in order to become compliant with the new regulations. After making changes in the schedule, two more surveys were completed and evaluated, once in May 2003 and again in November 2003. Final analyses compared results from May 2002 to November 2003. Surveys were distributed to 30 residents in May 2002. Twenty-two residents completed the survey with 16 surveys eligible for analysis following exclusion of abnormal rotations (i.e., research and vacation). Eighty-eight per cent of junior residents (PGY 1, 2, and 3), 50 per cent of senior residents (PGY 4-5), and 33 per cent of chief residents (PGY 6) worked more than 88 hours per week. In November 2003, surveys were sent to 32 residents. Twenty-four residents who were on our normal call schedule completed the survey. Fourteen per cent of junior residents, 33 per cent of senior residents, and 0 per cent of chief residents worked more than 88 hours per week. By making the changes described, we have substantially reduced the number of resident work-hours while maintaining our academic and patient care missions.

The impact of pelvic and lower extremity fractures on the incidence of lower extremity deep vein thrombosis in high-risk trauma patients. Winner of the Best Paper Award from the Gold Medal Forum.

Lower extremity fractures (LEFx) and pelvic fractures (PFx) are believed to increase the risk of lower extremity deep vein thrombosis (LEDVT). We studied trauma patients at high risk for LEDVT to determine whether an increased incidence of LEDVT was associated with LEFx and/or PFx. From January 1995 through December 1997 4163 trauma patients were admitted to our Level I trauma center. One thousand ninety-three patients at high risk for LEDVT were screened with serial lower extremity venous duplex ultrasound. Their medical records were retrospectively reviewed for demographics, mechanism of injury, and fracture data. The occurrence of LEDVT, pulmonary embolus, and LEDVT prophylaxis and treatment were noted. The incidence of LEDVT in the fracture group (Fx) was compared with that in the nonfracture group (NFx) using chi-square analysis and logistic regression. Statistical significance was set at < or = 0.05. Complete data were available for 1059 of 1093 patients. Five hundred sixty-nine (53.73%) patients had PFx and/or LEFx, 151 (14.26%) patients had PFx only, 317 (29.3%) patients had LEFx only, and 101 (9.54%) patients had both PFx and LEFx. Four hundred ninety (46.27%) patients had NFx. In 1059 patients LEDVT was detected in 125 (11.8%). Sixty-three patients in the Fx groups developed LEDVT (50.4%): 19 (15.2%) PFx patients, 15 (12.0%) PFx/LEFx patients, and 29 (23.2%) LEFx patients. Sixty-two (49.6%) NFx patients developed LEDVT. LEDVT incidence was not significantly different between the Fx and NFx groups or among the PFx, LEFx, and PFx/LEFx groups (P = 0.317). Nine patients developed pulmonary embolism: four NFx patients, two LEFx patients, two PFx patients, and one PFx/LEFx patient. Significant predictors of LEDVT were age and hospital length of stay. Mean age in patients with LEDVT was 47.58 years and in patients without LEDVT it was 40.89 years (P < 0.001). Mean hospital length of stay in patients with LEDVT was 29.81 days and in patients without LEDVT it was 16.84 days. The power of this study to detect differences representing medium effect sizes was greater than 90 per cent. We conclude that LEFx and/or PFx was not associated with an increased incidence of LEDVT in trauma patients at high risk for LEDVT. Lower extremity venous duplex ultrasound needs to be performed in both Fx and NFx groups to detect LEDVTs.
