Abstract
Background: Small bowel obstruction (SBO) is a common disorder managed by surgeons. Despite extensive publications and management guidelines, there is no universally accepted approach to its diagnosis and management. We conducted a survey of acute care surgeons to elucidate their SBO practice patterns.Methods: A self-report survey of SBO diagnosis and management practices was designed and distributed by email to AAST surgeons who cared for adult SBO patients. Responses were analyzed with descriptive statistics and Chi-square test of independence at α = .05.Results: There were 201 useable surveys: 53% ≥ 50 years, 77% male, 77% at level I trauma centers. Only 35.8% reported formal hospital SBO management guidelines. Computed tomography (CT) scan was the only diagnostic exam listed as "essential" by the majority of respondents (82.6%). Following NG decompression, 153 (76.1%) would "always/frequently" administer a water-soluble contrast challenge (GC). There were notable age differences in approach. Compared to those ≥50 years, younger surgeons were less likely to deem plain abdominal films as "essential" (16.0% vs 40.2%; P < .01) but more likely to require CT scan (88.3% vs 77.6%; P = .045) for diagnosis and to "always/frequently" administer GC (84.0% vs 69.2%; P < .01). Younger surgeons used laparoscopy "frequently" more often than older surgeons (34.0% vs 21.5%, P = .05).Discussion: There is significant variation in diagnosis and management of SBO among respondents in this convenience sample, despite existing PMGs. Novel age differences in responses were observed, which prompts further evaluation. Additional research is needed to determine whether variation in practice patterns is widespread and affects outcomes.

Findings on Repeat Posttraumatic Brain Computed Tomography Scans in Older Patients With Minimal Head Trauma and the Impact of Existing Antithrombotic Use. Ann Emerg Med 2023; 81:364-374. [PMID: 36328853 DOI: 10.1016/j.annemergmed.2022.08.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2022] [Revised: 07/20/2022] [Accepted: 08/02/2022] [Indexed: 11/11/2022]
Abstract
STUDY OBJECTIVE Evaluate the utility of routine rescanning of older, mild head trauma patients with an initial negative brain computed tomography (CT), who is on a preinjury antithrombotic (AT) agent by assessing the rate of delayed intracranial hemorrhage (dICH), need for surgery, and attributable mortality. METHODS Participating centers were trained and provided data collection instruments per institutional review board-approved protocols. Data were obtained from manual chart review and electronic medical record download. Adults ≥55 years seen at Level I/II Trauma Centers, between 2017 and 2019 with suspected head trauma, Glasgow Coma Scale 14 to 15, negative initial brain CT, and no other Abbreviated Injury Scale injuries >2 were identified, grouped by preinjury AT therapy (AT- or AT+) and compared on dICH rate, need for operative neurosurgical intervention, and attributable mortality using univariate analysis (α=.05). RESULTS A total of 2,950 patients from 24 centers were enrolled; 280 (9.5%) had a repeat brain CT. In those rescanned, the dICH rate was 15/126 (11.9%) for AT- and 6/154 (3.9%) in AT+. Assuming nonrescanned patients did not suffer clinically meaningful dICH, the dICH rate would be 15/2001 (0.7%) for AT- and 6/949 (0.6%) for AT+. No surgical operations were done for dICH. All-cause mortality was 9/2950 (0.3%) and attributable mortality was 1/2950 (0.03%). The attributable death was an AT+, dICH patient whose family declined intervention. CONCLUSION In older patients with an initial Glasgow Coma Scale of 14 to 15 and a negative initial brain CT scan, the dICH rate is low (<1%) and of minimal clinical consequence, regardless of AT use. In addition, no patient had operative neurosurgical intervention. Therefore, routine rescanning is not supported based on the results of this study.

Abstract
Desirability of outcome ranking and response adjusted for duration of antibiotic risk (DOOR/RADAR) are novel and innovative methods of evaluating data in antibiotic trials. We analyzed data from a noninferiority trial of short-course antimicrobial therapy for intra-abdominal infection (STOP-IT), and results suggest global superiority of short-duration therapy for intra-abdominal infections.

Abstract
BACKGROUND The purpose of this trial was to determine if using a closed technique for bladder pressure measurements (BPMs) would eliminate them as a risk factor for urinary tract infection (UTI) in trauma patients, as was shown previously using an open technique. METHODS Data were collected prospectively from January 2006 until December 2009 by a dedicated epidemiology nurse and combined with trauma registry data at our Level 1 trauma center. All trauma patients admitted to the surgical trauma intensive care unit (STICU) with and without UTIs were compared for demographic and epidemiologic data. A closed system was used in which the urinary drainage catheter (UDC) remained connected to the bag and 45 mL of saline was injected through a two-way valved sideport, with subsequent measurements through the sideport. RESULTS There were 1,641 patients in the trial. The UTI group was sicker (Injury Severity Score [ISS] 18.7±11.9 no UTI vs. 28±10.7 UTI; p<0.0001), with longer stays (11.4±12.4 days no UTI vs. 37.9±20.3 days UTI; p<0.0001) and more UDC days (4.3±6.6 no UTI vs. 23.9±16.6 UTI; p<0.0001). The BPM group had more UDC days (15.6 days±16.0 BPM vs. 5.4 days±7.3 no BPM; p<0.0001), yet no difference in UTI rate/1,000 UDC days (5.7 no BPM vs. 8.0 BPM; p=0.5291). Logistic regression demonstrated only UDC days to be a predictor of UTI (1.125; 95% confidence interval [CI] 1.097-1.154; p<0.0001), whereas ISS (1.083, 95% CI 1.063-1.104; p<0.0001) and age (1.051, 95% CI 1.037-1.065; p<0.0001) were the only predictors of death. CONCLUSION Although patients undergoing BPM have more UTIs than patients without BPM, the measurements are not an independent predictor of UTI when done by the closed technique. These findings emphasize the judicious use of BPM with a closed system and, more importantly, the need for early removal of catheters.

Geriatric education for surgical residents: identifying a major need. Am Surg 2011; 77:826-831. [PMID: 21944342] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 05/31/2023]
Abstract
This study evaluated a program designed to test and enhance residents' knowledge of geriatrics. A 2-year prospective interventional trial was conducted. Surgical residents underwent pretesting (pre) in three areas: polypharmacy, delirium, and end of life. They then received educational materials and completed a posttest within 1 month and a patient simulation examination graded by a physician observer and the patient on his or her satisfaction. Forty-nine residents (51% interns, 55% general surgery residents) participated. Seventy per cent had no prior geriatrics education. Test scores significantly improved from pretest to posttest (12.9 ± 3.1 vs 13.78 ± 3.12, P = 0.01). The scores were consistently better on poly topics and consistently worse on end-of-life topics: pretest per cent correct: polypharmacy 60, end of life 46, P = 0.007; posttest percent correct: polypharmacy 63, end of life 49, P = 0.0014. By Pearson correlation, the pretest and posttest scores did not correlate with either the observer (R = -0.16, P = 0.27 pre, R = -0.08, P = 0.59 post) or subscores (R = -0.27, P = 0.11 pre, R = -0.13, P = 0.45 post), although the observer and subscore correlated with each other (R = 0.35, P = 0.036). Performance was poor and did not correlate with better patient care by simulation. Other options for geriatric education need to be considered and evaluated.

Abstract
PURPOSE To determine the risk factors for urinary tract infections (UTIs) specific to trauma patients in order to assist in the development of infection control protocols. METHODS Data were collected prospectively from January 2003 until December 2005 by an epidemiology nurse and combined with registry data from our Level 1 trauma center. The trauma patients admitted to the Surgery and Trauma Intensive Care Unit (STICU)(n = 938) who did and did not have UTIs were compared for demographics, Injury Severity Score (ISS), and epidemiologic data, including use of Foley catheters and bladder pressure measurements (BPMs). An open system was used for the measurements in which the catheter was disconnected from the bag to instill 50 mL of saline into the bladder, and an 18-gauge needle was inserted into the catheter to measure the pressure. RESULTS A total of 50 patients had no Foley catheter or UTIs. Among the 836 patients with catheters but no BPMs, there were 36 UTIs (4.31%), whereas the 52 patients with catheters and BPMs had 12 UTIs (23.08%)(p < 0.0001). Patients with UTIs were more severely injured older females (mean age 40.1 ± 18.6 years with no UTI vs. 48.5 ± 20.8 with UTIs; p = 0.0083; percent female 26.4 no UTI vs. 45.8 UTI; p = 0.007; ISS 19.3 ± 11.3 no UTI vs. 26.2 ± 11.6; p < 0.0001). Using logistic regression, BPM was an independent predictor of UTI, with infection being seven times more likely in the patients having the measurements (odds ratio [OR] 6.99; 95% confidence-interval [CI] 3.087-15.827). Along with age (OR 1.039; CI 1.024-1.054) and ISS (OR 1.081; CI 1.056-1.106), having BPMs was an independent predictor of death (OR 2.475; CI 1.191-6.328). CONCLUSION This is the first study that demonstrates a greater risk of UTI with BPM using the open technique independent of patient gender or degree of injury. Given these findings and a previous trial demonstrating no difference in UTI rates with a closed circuit for BPM, our institution has incorporated a closed circuit technique into its infection control protocol.

Abstract
We hypothesized that flexion extension (FE) films do not facilitate the diagnosis or treatment of ligamentous injury of the cervical spine after blunt trauma. From January 2000 to December 2008 we reviewed all patients who underwent FE films and compared five-view plain films (5view) and cervical spine CTC with FE in the diagnosis of ligamentous injury. There were 22,929 patients with blunt trauma and of these, 271 patients underwent 303 FE films. Average age was 39.6 years, Injury Severity Score was 10.8, Glasgow Coma Score was 14.1, lactate was 2.6 mmol/L, and hospital length of stay was 6 days. Compared with FE, 5view and CTC had a sensitivity of 80 per cent (8 of 10), positive predictive value of 47.1 per cent (8 of 17), specificity of 96.55 per cent (252 of 261), and negative predictive value of 99.21 per cent (252 of 254). For purposes of analysis, incomplete and ambiguous FE films were listed as negative; however, 20.5 per cent (62 of 303) were incomplete and 9.2 per cent (28 of 303) were ambiguous. Management did not change for the 2 patients with missed ligament injuries. The 303 studies cost $162,105.00 to obtain. FEs are often incomplete and unreliable making it difficult to use them to base management decisions. They do not facilitate treatment and may lead to increased cost and prolonged cervical collars.

Abstract
The purpose of this study was to compare flexion-extension (FE) plain films with MRI as the gold standard in the diagnosis of ligamentous injury (LI) of the cervical spine after trauma. A retrospective review of patients sustaining blunt trauma from January 2000 to December 2008 (n = 22929) who had both FE and MRI of the cervical spine was performed. Two hundred seventy-one patients had 303 FE films. Forty-nine also had MRI. The average Injury Severity Score was 15.6 +/- 10.2, Glasgow Coma Scale was 13.8 +/- 3.5, lactate 2.2 +/- 1.7 mmol/L, and hospital stay of 8 +/- 11.2 days. FE failed to identify all eight LIs seen on MRI. FE film sensitivity was 0 per cent (zero of eight), specificity 98 per cent (40 of 41), positive predictive value 0 per cent (zero of one), and negative predictive value 83 per cent (40 of 48). Although classified as negative for purposes of analysis, FE was incomplete 20.5 per cent (62 of 303) and ambiguous 9.2 per cent (28 of 303) of the time. The charge of FE is $535 so $48150 (90 incomplete/ambiguous films) could have been saved by eliminating these films. FE should no longer be used to diagnose LI. Given the rare incidence of these injuries, MRI should be used when there is high clinical suspicion of injury.

Abstract
We evaluated the benefit of a central venous line (CVL) protocol on bloodstream infections (BSIs) and outcome in a trauma intensive care unit (ICU) population. We prospectively compared three groups: Group 1 (January 2003 to June 2004) preprotocol; Group 2 (July 2004 to June 2005) after the start of the protocol that included minimizing CVL use and strict universal precautions; and Group 3 (July 2005 to December 2006) after the addition of a line supply cart and nursing checklist. There were 1622 trauma patients admitted to the trauma ICU during the study period of whom 542 had a CVL. Group 3 had a higher Injury Severity Score (ISS) compared with both Groups 2 and 1 (28.3 +/- 13.0 vs 23.5 +/- 11.7 vs 22.8 +/- 12.0, P = 0.0002) but had a lower BSI rate/1000 line days (Group 1: 16.5; Group 2: 15.0; Group 3: 7.7). Adjusting for ISS group, three had shorter ICU length of stay (LOS) compared with Group 1 (12.11 +/- 1.46 vs 18.16 +/- 1.51, P = 0.01). Logistic regression showed ISS (P = 0.04; OR, 1.025; CI, 1.001-1.050) and a lack of CVL protocol (P = 0.01; OR, 0.31; CI, 0.13-0.76) to be independent predictors of BSI. CVL protocols decrease both BSI and LOS in trauma patients. Strict enforcement by a nurse preserves the integrity of the protocol.

Abstract
We examined the outcome of elderly trauma patients with pelvic fractures. Patients 65 years of age and older (elderly) with pelvic fractures were retrospectively compared with patients younger than 65 years with pelvic fractures and also with elderly patients without fracture. Over the study period, 1223 patients sustained a pelvic fracture (younger than 65 years, n = 1066, 87.2%; elderly, n = 157,12.8%). These patients were also compared with 1770 elderly patients with blunt trauma without fracture. Although the pelvic fracture patients were equally matched for Injury Severity Score (21.2 ± 13.4 nonelderly vs 20.5 ± 13.6 elderly), hospital length of stay was increased in the elderly (12.5 ± 13.1 days vs 11.5 ± 14.1 days) and they had a higher mortality rate (20.4% [32 of 157] vs 8.3% 88 of 1066]). The elderly without fracture also had a higher mortality rate when compared with the younger patients (10.9% [191 of 1760]; P < 0.03). The elderly were more likely to die from multisystem organ failure (25.0% [eight of 32] vs 10.2% [nine of 88]), whereas the nonelderly group was more likely to die from exsanguination (45.5% [40 of 88] younger than 65 years vs 21.9% [seven of 32] 65 years or older; P < 0.05). Elderly patients with pelvic fracture have worse outcomes than their younger counterparts despite aggressive management at a Level I trauma center.

Abstract
The objective of this study was to determine if clinical examination accurately ruled out pelvic fractures in intoxicated patients sustaining blunt trauma A prospective comparison of intoxicated (blood alcohol level [BAL] greater than 0.08 g/dL) to nonintoxicated (BAL less than 0.08 g/dL) patients sustaining blunt trauma was performed between February 2004 and March 2007. Clinical factors were compared and subset analysis performed in which patients with factors known to compromise the clinical examination were excluded. Two hundred ninety-six intoxicated patients were compared with 1071 nonintoxicated patients. Intoxicated patients were younger and more often male. Intoxicated patients had a higher heart rate (97.1 beats/min ± 17.9 vs 91.4 beats/min ± 18.7, P < 0.0001) and lower systolic blood pressure (136.2 mmHg ± 21.2 vs 141.9 mmHg ± 26.6, P = 0.0005) than nonintoxicated patients. Intoxicated patients had a lower incidence of pelvic fracture (6.1 vs 10.6%). In subset analysis, the majority of the intoxicated patients did not have exclusion factors on examination and could be evaluated (66.6%). There were eight pelvic fractures diagnosed in this group and no missed injuries on clinical examination (sensitivity 100%). Clinical examination was not compromised by intoxication. Routine pelvic x-rays are not needed in the alert, intoxicated patient sustaining blunt trauma.

Abstract
We sought to determine the effect of anticoagulation therapy on outcomes in elderly patients with closed head injury. We retrospectively reviewed elderly closed head injury patients (> or = 65 years) comparing 52 patients on warfarin (AC) with 439 patients not on warfarin (NAC) with subsequent 1:3 propensity matching used to analyze comparable groups. The overall AC group had a higher head abbreviated injury score (AIS) (4.0 +/- 0.7 vs 3.8 +/- 0.7, P = 0.04) compared with the NAC group. After propensity matching, 49 AC patients were compared with 147 NAC patients who were similar for age, gender, injury severity score, and head AIS. Admission INR was higher in the AC group compared to the NAC group (2.5 +/- 1.3 vs 1.1 +/- 0.3, P < 0.0001) and the AC group had a higher mortality rate (38.8% AC (19/49) vs 23.1% NAC (34/147), P = 0.04). In the AC group, survivors and nonsurvivors had similar repeat International Normalized Ratio (INR) values (1.57 +/- 0.65 survivors vs 1.8 +/- 0.72 nonsurvivors, P = 0.31). The AC group experienced greater morbidity after trauma and had higher mortality rates than their NAC counterparts. Prevention of injury and more selective use of warfarin in this patient population are essential to decrease mortality.

Abstract
We prospectively compared clinical examination (CE) with plain films (PXR) and both tools with CT in patients sustaining blunt trauma. There were 1388 patients who had both PXR and CT of whom 168 (12.1%) were diagnosed with a fracture by CT. CE findings most predictive of fracture included age (OR, 1.025; CI, 1.011-1.039), hip pain (OR, 4.971; CI, 2.508-9.854), internal rotation of the leg (OR, 4.880; CI, 1.980-12.027), or tenderness to palpation over the sacrum (OR, 2.297; CI, 1.144-4.612), over the right or left hip (OR, 3.626; CI, 1.823-7.214), or diffusely throughout the pelvis (OR, 16.445; CI, 4.277-63.237). These factors were still predictive of pelvic fractures even in patients with a Glasgow Coma Scale score less than 13. There were 136 fractures identified by PXR all of which were identified by CE (sensitivity 100% [136 of 136], negative predictive value 100% [619 of 619]). There were six patients with negative clinical examinations and positive CTs (sensitivity 96.4% [162 of 168], negative predictive value 99.03% [613 of 619]), none of which were hemodynamically significant. The sensitivity for PXR compared with CT was 79.17 per cent (133 of 168) and the NPV was 97.2 per cent (1217 of 1252). CE is a reliable way to diagnose pelvic fractures and PXR is a poor screening tool for these injuries compared with CT. Because the majority of patients undergo CT after blunt trauma, routine screening radiographs should be eliminated.

The effect of anemia and blood transfusions on mortality in closed head injury patients. J Surg Res 2008; 147:163-7. [PMID: 18498864 DOI: 10.1016/j.jss.2008.02.044] [Citation(s) in RCA: 35] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2007] [Revised: 02/12/2008] [Accepted: 02/12/2008] [Indexed: 10/22/2022]
Abstract
BACKGROUND The purpose of this study was to determine if anemia in isolated head trauma patients results in a higher mortality rate that would justify a more liberal use of blood transfusions. METHODS A retrospective review of isolated blunt head trauma patients was performed between January 2001 and December 2006. Comparisons were made between survivors and nonsurvivors regarding demographics, laboratory values, transfusions received, and lengths of stay. RESULTS There were 788 patients with 735 survivors who were significantly younger (46.3 y +/- 21.5 survivors versus 68.9 y +/- 18.8 nonsurvivors, P < 0.0001) and less injured [(ISS: 14.7 +/- 5.2 survivors versus 23.2 +/- 4.7 nonsurvivors, P < 0.0001), (head abbreviated injury severity: 3.7 +/- 0.7 survivors versus 4.7 +/- 0.5 nonsurvivors, P < 0.0001)] than those who died (n = 53). The survivors also had shorter lengths of stay (days) [(ICU: 2.4 +/- 4.2 versus 5.6 +/- 11.7, P = 0.03), (hospital: 6.3 +/- 9.8 versus 7.8 +/- 14.8, P = 0.02)]. Multivariate logistic regression showed age (OR 1.063, CI 1.042-1.084), ISS (OR 1.376, CI 1.270-1.491), minimum hemoglobin (OR 0.855, CI 0.732-1.000), and total blood products transfused (OR 1.073, CI 1.008-1.142) to be independent predictors of mortality with an ROC of 0.942. Outcome was independent of the operative procedures, hematocrit and packed red blood cells transfused at 24, 48, and 72 h. Hemoglobin levels of <8 mg/dL were more predictive of death than >8 mg/dL (P = 0.01). CONCLUSIONS This study supports the need to balance mild anemia with judicious blood product use in the head trauma patient. Given the risk with blood product use, each transfusion should be carefully considered and the patient re-evaluated regularly to determine the need for further intervention.

Abstract
BACKGROUND The Eastern Association for the Surgery of Trauma (EAST) guidelines recommend that cervical spine (c-spine) radiographic evaluation is unnecessary in the awake, alert blunt trauma patient who is not intoxicated, has no distracting injuries, and demonstrates no tenderness over the c-spine or neurologic deficits. The purpose of this study was to compare the reliability of the clinical examination (CE) with that of computed tomography in identifying the presence of c-spine fractures. METHODS We prospectively evaluated 534 blunt trauma patients between February 2004 and January 2005. Positive CE was defined as complaints of neck pain, external trauma of the c-spine or neurologic deficit, tenderness or abnormalities to palpation over the cervical spine. Computed tomography was used to define the accuracy of CE. RESULTS There were 52 patients with, and 482 patients without, c-spine fractures. Forty of the 52 patients with fractures were accurately identified by CE for a sensitivity of 76.9% and a negative predictive value (NPV) of 95.7%. In the group with an initial Glasgow Coma Score of 15, 16 of 24 patients with fractures were accurately identified for a sensitivity of 66.7% and an NPV of 96.5%. In the subset of patients who by EAST guidelines would not require any radiographic evaluation, there were 17 fractures and 10 were accurately identified by clinical examination. The sensitivity in this group was 58.8% with an NPV of 96.4%. Four of the seven missed injuries required intervention. CONCLUSIONS This trial suggests that with a normal Glasgow Coma Score, CE cannot be relied upon to rule out c-spine fracture. CE is unreliable to diagnose or exclude a cervical spine fracture.

Abstract
BACKGROUND Obesity has proven to be an independent risk factor of mortality in the intensive care unit (ICU) in both nontrauma and trauma patients. The purpose of this study was to determine whether the detrimental effect of obesity extend to morbidity as well as mortality in the intensive and nonintensive care blunt trauma patients. METHODS A retrospective comparison of obese (body mass index [BMI] > 30 kg/m2) to nonobese (BMI < 30 kg/m2) blunt trauma patients was performed between January 2004 and December 2005. Patient demographics, morbidity, mortality and ventilator, ICU, and hospital length of stays were analyzed. Continuous variables were evaluated using the Wilcoxon Rank test and the nominal variables were evaluated using the Fisher's exact test. RESULTS A cohort of 338 nonobese patients was compared with 115 obese patients during the study. These groups were similar in age (p = 0.19), gender (p = 0.37), and mechanism (p = 0.13). Their severity of injury were similar, demonstrated by nonsignificant differences in Injury Severity Score (p = 0.45), New Injury Severity Score (p = 0.51), Abdomen Abbreviated Injury Score (AIS; p = 0.49), and head AIS (p = 0.64). The subset of obese patients who never went to the ICU had a slightly longer hospital stay with a p value of 0.055. Overall the mortality rates were not different between the groups (3.5% obese versus 7.1% nonobese, p = 0.26). CONCLUSIONS This group of obese blunt trauma patients had similar mortality rates to their leaner counterparts possibly because their complications were minimized. Despite this finding, a subset of obese patients had longer hospital stays which increases the financial burden to the patient and hospital. Effort should be made to facilitate their discharge to avoid complications and minimize cost.

Is blood sugar the next lactate? Am Surg 2006; 72:613-7; discussion 617-8. [PMID: 16875083] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 05/11/2023]
Abstract
This study evaluates whether an initial blood glucose level is similarly predictive of injury severity and outcome as admission lactate in trauma patients. Between February 2004 and June 2005, we prospectively compared patients with presenting blood sugars of < or =150 mg/dL (LBS) with those with blood sugars >150 mg/dL (HBS). Fifty patients had BS above 150 mg/dL, whereas 176 patients were < or = 150 mg/dL. These groups had similar demographics except for age. Injury Severity Score (ISS) of > or = 15 was seen in 56.0 per cent of HBS patients versus 28.4 per cent of LBS patients (P = 0.0006). HBS patients had similar infection rates (12.0% HBS vs. 5.7% LBS, P = 0.13) but a higher mortality (30.0% HBS vs. 5.7% LBS, P < 0.0001). There was a linear relationship between ISS and BS (r2 = 0.18, P < 0.0001) and ISS and lactate (r2 = 0.17, P < 0.0001). Blood sugar trended with the lactate (r = 0.25, P = 0.0001). Hyperglycemic patients were more severely injured with higher mortality. BS correlated with lactate, and because it is easily obtainable, it may serve as a readily available predictor of injury severity and prognosis.

Abstract
Little data exists regarding extubation protocols in critically injured trauma patients. The objective of the current study was to prospectively examine the impact of implementing an extubation protocol on the outcomes of ventilated trauma patients in a surgical intensive care unit (STICU). Trauma patients admitted to the STICU over a 15-month period at a Level 1 trauma center were prospectively evaluated. The total period was divided into an education and institution period (April 2002-November 2003) and an evaluation period (December 2003-July 2003). Patient demographics, hospital course, complications, and outcomes from period I were compared with those obtained during period II. From April 8, 2002 through July 5, 2003, 69 patients intubated for greater than 24 hours were included in our analysis. Thirty-three were treated during period I and 36 were treated during period II. Both groups were well matched in terms of age, sex, Injury Severity Score, and chest Abbreviated Injury Score. Ventilation days significantly decreased from a mean of 16.3 to 8.2 days (P = 0.04). ICU length of stay also decreased, nearly meeting significance. A rigorously enforced extubation protocol significantly decreased ventilator days in STICU patients. Continued education of health care providers is key to the success of the protocol.

Abstract
Preventing hurricane-related injuries (HRI) has historically centered on the pre-event and event phases of the disaster. To date, no study has focused on injuries occurring during the postevent phase. We examined HRI that occurred after Hurricane Isabel struck a U.S. urban city. HRI presenting 1 week prior to the hurricane were collected from emergency department electronic records. HRI that presented to our level 1 trauma center were prospectively collected for 1 week after the hurricane. Nine hundred seventy-eight patients with possible HRI were identified. Fifty-one patients with trauma directly attributed to the hurricane were used for analysis. The number of HRI occurring before, during, and after the hurricane were 7 (14%), 3 (6%), and 41 (80%), respectively. The majority of HRI (37%) occurred on posthurricane day 1. Head, chest, upper and lower extremities accounted for 9 (18%), 8 (16%), 13 (26%), and 14 (28%) of HRI. More than one third of HRI patients were admitted to the hospital, and 12 (24%) underwent an operation. The average hospital length of stay was 4.7 days. Of our trauma alerts, 75 per cent had an Injury Severity Score (ISS) >8, and 20 per cent had an ISS >15. Tree-related injuries (TRI) accounted for 59 per cent of HRI. Males, ages 50-60, had the highest incidence of injury (63%). Significant injuries occur in the wake of a hurricane. Optimization of disaster preparation must include prevention strategies targeted to the postevent recovery phase of disasters.

Abstract
BACKGROUND The purpose of this study was to identify risk factors that predict the need for operative management (OM) of severe blunt liver injury. We also sought to determine the impact of interventional angiography (Ang) in the treatment and outcomes of these patients. METHODS Patients with blunt liver injuries of grade IV or higher were retrospectively reviewed for their demographics, hemodynamics, blood product requirements, laboratory and radiologic data, hospital course, and outcomes. RESULTS Forty-four patients underwent OM. They had a significantly higher Injury Severity Score (ISS) and lower Glasgow Coma Scale score (p = 0.004), a lower systolic blood pressure (p = 0.002) and a higher heart rate (p = 0.02), and higher fluid and transfusion requirements (p < 0.001) than those treated without OM. Their mortality rate was 66%; 59% of deaths were from uncontrolled bleeding. Initial platelet count and fluid requirements at 4 hours were independent predictors of the need for OM. Ang was performed in 48 patients. Patients who were treated without Ang required more fluids (p = 0.03) and more packed red blood cells (p = 0.02) at 4 hours. Patients requiring both OM and Ang had a higher complication rate (p = 0.02) and longer intensive care unit and hospital length of stay (p < 0.001) than those who had OM alone, but mortality was the same (p = 0.1). Patients treated nonoperatively had longer intensive care unit (p = 0.006) and hospital stays (p < 0.05) if they required Ang, but mortality was the same. The only survival advantage to the use of Ang was when Ang alone was compared with OM alone. CONCLUSION Select high-grade injuries can be successfully managed nonoperatively. Initial platelet count and crystalloid fluid use at 4 hours predict the need for OM. Patients requiring OM are less stable and have substantial mortality but often do not die as a result of uncontrolled bleeding. Ang has a role in stable patients who do not require OM initially but does not improve outcome in patients who require OM.

Abstract
HYPOTHESIS The use of weaning and sedation protocols affects the intensive care unit (ICU) course of a trauma population. DESIGN Nonrandomized before-after trial. SETTING A level I trauma center. PATIENTS Three hundred twenty-eight consecutive trauma patients receiving mechanical ventilation treated in the ICU between October 1, 1997, and November 1, 1999. INTERVENTION Sedation and weaning protocols were used to treat patients receiving mechanical ventilation during the second year of this study. MAIN OUTCOME MEASURES Self-extubation rates, ventilator days, number of ICU days, and charges. RESULTS There were 168 patients in the preprotocol group (year 1: October 1, 1997, to October 31, 1998) and 160 patients in the postprotocol group (year 2: November 1, 1998, to November 30, 1999). The groups were similar in age (P =.68), Injury Severity Score (P =.06), and Glasgow Coma Scale score (P =.29). There were no differences in self-extubation rates (P =.57), ventilator days (P =.83), ventilator charges (P =.83), number of ICU days (P =.67), or ICU charges (P =.67) between the 2 groups. No statistical difference was identified in any of these categories when long-term ventilator patients (defined as ventilator length of stay > or =3 SDs above the mean) were excluded. CONCLUSIONS Use of weaning and sedation protocols did not affect the measured outcomes in this study. These findings may reflect difficulties inherent in the protocols or with their utilization. Further subgroup analysis focusing on ventilator-associated pneumonias and mortality may demonstrate benefits not identified herein.

Abstract
BACKGROUND We hypothesized that clinical factors accurately identify those trauma patients at high risk for pelvic fractures making routine films unnecessary. METHODS Blunt trauma patients were prospectively analyzed both with and without a clinical protocol. The protocol group had pelvic films obtained only if they had a Glasgow Coma Scale score < 13 or had signs and symptoms of pelvic or back injury. RESULTS The protocol patients with fractures (n = 45) had a higher Injury Severity Score (p = 0.001) and lower systolic blood pressure (p = 0.04) than those without fractures (n = 475). All 45 patients with pelvic fractures were identified by history and physical examination (p = 0.001). The clinical assessment resulted in a sensitivity and a negative predictive value of 100%. A total of 273 films were eliminated, resulting in a charge savings of $51,051. A comparison between the protocol and nonprotocol groups showed the nonprotocol patients with pelvic fractures to have a higher Injury Severity Score (p < 0.002). All of these patients' pelvic fractures were identified by clinical evaluation (67 of 67). CONCLUSION In the awake and alert patient, the need for a pelvic radiograph was readily identified by clinical examination. Because elimination of this film would result in financial savings, its routine use should be removed from standard trauma protocols in the minimally injured patient and limited to severely injured patients as recommended by the Advanced Trauma Life Support protocol.

Abstract
We evaluated clinical factors that are predictive of pelvic X-ray findings. We sought to identify whether routine pelvic films are necessary in blunt trauma and addressed whether removal of these films would minimize cost. We performed a retrospective chart review of 111 patients without pelvic fractures and 108 with pelvic fractures seen at our Level 1 trauma center between August 1998 and September 1999. We evaluated initial hemodynamics, physical examination findings, laboratory data, and hospital charges. Patients with fractures had higher Injury Severity Scores ( P < 0.001), a higher number of associated injuries ( P < 0.001), and lower blood pressures ( P < 0.001). The back and pelvic examinations were significantly associated with X-ray results ( P < 0.001), and the potential savings with selective radiography was $168,300.00 per year. We believe that clinical factors identified in our study predict the need for pelvic X-ray. Because removal of these films would minimize cost we recommend the elimination of routine pelvic films for the awake and alert blunt trauma patient.

Abstract
Intussusception is a common pediatric surgical problem. Its occurrence in adults is rare and usually involves a specific lead point such as a small bowel tumor or other mass. We describe two adults who developed intussusception after Roux-en-Y gastric bypass. Signs and symptoms of small bowel obstruction were seen in both of these patients, but the responsible pathology was unusual. Because of the increasing frequency with which these gastric bypass procedures are being performed, a high index of suspicion must be employed when dealing with these postoperative patients who present with abdominal complaints.
