Prehospital Traction Splint Use in Midthigh Trauma Patients.

CONTEXT: Traction splint (TS) use during emergency medical system transport has been theorized to relieve pain, limit continued injury from loose bone fragments, and decrease potential bleeding space in the injured thigh. AIMS: This study aimed to evaluate the benefit of prehospital TS (PTS) application, using data from the trauma registry at a large Level 1 trauma center. METHODS: A retrospective review of patients from the NTRACS© and Trauma One© registry at an American College of Surgeons-verified Level 1 trauma center was conducted. All patients treated between the years 2001 and 2011 who were assigned a diagnosis International Classification of Diseases-9 code of 821.01 (closed fracture of shaft and femur) and 821.11 (open fracture of shaft and femur) (femur fracture [FF]) were included. STATISTICAL ANALYSIS: All categorical variables between the first groups were compared using Pearson's Chi-square and Fisher's exact test analysis. Comparisons were made using unpaired t-tests and Mann-Whitney test or Kruskal-Wallis one-way ANOVA, followed by Dunn's post hoc pairwise comparisons. RESULTS: Patients with a TS and those without indicated that the patients with no traction split (NTS) had sustained injuries beyond a FF (14.43 ± 9.740 vs. 18.59 ± 12.993, P < 0.001). The three groups of TS placement (PTS, hospital, and NTS) only used patients with Injury Severity Score < 9 (n = 218). Hospital length of stay (LOS) was found to be significant (P = 0.05) between the patients who received a hospital TS (3.10 ± 1.709) and NTS (5.42 ± 5.144). CONCLUSION: PTS can lower LOS and mortality. Further research is needed to confirm these findings.

Criteria for excision of suspected fibroadenomas of the breast.

BACKGROUND: Fibroadenomas are benign breast tumors; however, more aggressive lesions may mimic or arise within fibroadenomas. We sought to define criteria identifying patients who should undergo surgical excision. METHODS: Patients with a preoperative diagnosis of fibroadenoma, who underwent surgical excision between 2002 and 2011, were retrospectively reviewed. Patients with final pathologic diagnosis of fibroadenoma were compared with those with non-fibroadenoma pathology. RESULTS: Of the 723 patients, 681 (94%) had fibroadenomas on final pathology. The incidence of non-fibroadenoma pathology was 6% (42 patients) and included benign phylloides (23), malignant phylloides (2), atypical ductal hyperplasia (1), intraductal papilloma (5), and other benign pathology (11). No cases of adenocarcinoma were identified. Non-fibroadenoma pathology was associated with age >35, immobile or poorly circumscribed mass, size >2.5 cm, and biopsy not definitive for fibroadenoma. CONCLUSION: Patients with age >35 years, immobile or poorly circumscribed mass, size >2.5 cm, or biopsy not definitive for fibroadenoma should undergo surgical excision.

Myths and Misinformation About Gunshot Wounds may Adversely Affect Proper Treatment.

BACKGROUND: Poorly designed experiments and popular media have led to multiple myths about wound ballistics. Some of these myths have been incorporated into the trauma literature as fact and are included in Advanced Trauma Life Support (ATLS). We hypothesized that these erroneous beliefs would be prevalent, even among those providing care for patients with gunshot wounds (GSWs), but could be addressed through education. METHODS: ATLS course content was reviewed. Several myths involving wound ballistics were identified. Clinically relevant myths were chosen including wounding mechanism, lead poisoning, debridement, and antibiotic use. Subsequently, surgery and emergency medicine services at three different trauma centers were studied. All three sites were busy, urban trauma centers with a significant amount of penetrating trauma. A pre-test was administered prior to a lecture on wound ballistics followed by a post-test. Pre- and post-test scores were compared and correlated with demographic data including ATLS course completion, firearm/ballistics experience, and years of post-graduate medical experience (PGME). RESULTS: One-hundred and fifteen clinicians participated in the study. A mean pre-test score of 34 % improved to 78 % on the post-test with associated improvements in all areas of knowledge (p < 0.001). Years of PGME correlated with higher pre-test score (p = 0.021); however, ATLS status did not (p = 0.774). CONCLUSIONS: Erroneous beliefs involving wound ballistics are prevalent even among clinicians who frequently treat victims of GSWs and could lead to inappropriate treatment. Focused education markedly improved knowledge. The ATLS course and manual promulgate some of these myths and should be revised.

Isolated free fluid on abdominal computed tomography in blunt trauma: watch and wait or operate?

BACKGROUND: Isolated free fluid (FF) on abdominal CT in stable blunt trauma patients can indicate the presence of hollow viscus injury. No criteria exist to differentiate treatment by operative exploration vs observation. The goals of this study were to determine the incidence of isolated FF and to identify factors that discriminate between patients who should undergo operative exploration vs observation. STUDY DESIGN: A review of blunt trauma patients at a Level I trauma center from July 2009 to March 2012 was performed. Patients with a CT showing isolated FF after blunt trauma were included. Data collected included demographics, injury severity, physical examination, CT, and operative findings. RESULTS: Two thousand eight hundred and ninety-nine patients had CT scans, 156 (5.4%) of whom had isolated FF. The therapeutic operative group included 13 patients; 9 had immediate operation and 4 failed nonoperative management. The nonoperative/nontherapeutic operation group consisted of 142 patients with successful nonoperative management and 1 patient with a nontherapeutic operation. Abdominal tenderness was documented in 69% of the therapeutic operative group and 23% of the nonoperative/nontherapeutic group (odds ratio = 7.5; p < 0.001). The presence of a moderate to large amount of FF was increased in the therapeutic operative group (85% vs 8%; odds ratio = 66; p < 0.001). CONCLUSIONS: Isolated FF was noted in 5.4% of stable blunt trauma patients. Blunt trauma patients with moderate to large amounts of FF without solid organ injury on CT and abdominal tenderness should undergo immediate operative exploration. Patients with neither of these findings can be safely observed.

An acute care surgery fellowship benefits a general surgical residency.

BACKGROUND: There has been a trend toward subspecialization among general surgery graduates, and many subspecialists are reticent to participate in trauma care. This has resulted in a gap in the provision of emergency surgical care. The Acute Care Surgery (ACS) fellowship, incorporating trauma, critical care, and emergency general surgery, was developed to address this need. One of the most important aspects in establishing these ACS fellowships is that they do not detract from the existing general surgery residents' experience. METHODS: The operative case logs for residents and fellows were compared for the number of resident cases during the 3 years before the ACS fellowship and during the 3 years after the fellowship was established. Surveys were distributed to the general surgery residents addressing the impact of the fellows from the resident's perspective at the end of the 2011 to 2012 academic year. RESULTS: There was no significant change in the number of total cases; total chief resident cases; and trauma, thoracic, or vascular procedures done per graduate. A decrease in the number of liver cases performed by the residents was noted but includes the increase in resident complement as well as the fellowship. ACS fellow cases increased from 172 cases in the first year to 221 cases in the second year and 295 in the third year. The survey showed that the residents had a very positive response to having the fellow as a teacher and did not feel like their operative experience was compromised with the addition of the ACS fellowship. CONCLUSION: The ACS fellow did not compromise general surgery resident experience and was regarded as an asset to the resident's education. An ACS fellowship can be beneficial to residents and fellows. LEVEL OF EVIDENCE: Care management study, level IV.

Post-extubation dysphagia in trauma patients: it's hard to swallow.

BACKGROUND: There is a significant incidence of unrecognized postextubation dysphagia in trauma patients. The purpose of this study was to evaluate the incidence, ascertain the risk factors, and identify patients with postextubation dysphagia who will require clinical swallow evaluation. METHODS: A prospective observational study was performed on 270 trauma patients. Bedside clinical swallow evaluation was done within 24 hours of extubation. Logistic regression analysis was used to adjust for confounding variables. RESULTS: The incidence of oropharyngeal dysphagia (OD) in our study was 42%. Ventilator days was the strongest independent risk factor for OD (3.6 vs 8.0, P < .001). The odds ratio showed a 25% risk for OD for each additional ventilator day. Silent aspiration was found in 37% of patients with OD. CONCLUSIONS: Trauma patients requiring mechanical ventilation for ≥2 days are at increased risk for dysphagia and should undergo routine swallow evaluations after extubation.

Predicting extubation failure in blunt trauma patients with pulmonary contusion.

BACKGROUND: The need for reintubation after weaning from mechanical ventilation (extubation failure) is associated with increased morbidity and mortality. In blunt trauma patients with pulmonary contusion, factors predicting successful weaning have not been reliably defined. The purpose of this study was to identify criteria predicting successful extubation in these patients. METHODS: Retrospective review during a 10-year period at a Level 1 trauma center was performed. A total of 173 extubations in 163 blunt trauma patients with pulmonary contusion requiring mechanical ventilation. Exclusion criteria include Glasgow Coma Scale (GCS) score of less than 9T before extubation, successful use of noninvasive positive-pressure ventilation after extubation, quadriplegia, and preextubation FIO2 of greater than 0.5. Data included age, Injury Severity Score (ISS), ventilator days, as well as GCS score, FIO2, the ratio of arterial oxygen tension to FIO2 (P/F ratio), and alveolar-arterial oxygen (A-a) difference at the time of extubation. Failure was defined as reintubation within 72 hours (excluding stridor or acute decline in GCS score). Mann-Whitney U-test, χ2 analysis, and logistic regression analysis determined variables associated with extubation failure. Odds ratios were used to compare P/F and A-a values associated with failed extubation. RESULTS: A total of 147 extubations (85%) were successful; 26 required reintubation. Patients did not differ by ISS, chest Abbreviated Injury Scale (AIS) score, presence of sternal or rib fractures, and admission pneumothorax or hemothorax. Increased age, A-a difference (≥ 120 mm Hg), and decreased P/F (<280) were associated with reintubation (p < 0.0001). By logistic regression analysis, P/F and A-a were independent variables for failed extubation; both remained independent risk factors when adjusted for age, ventilator days, GCS score, and preextubation FIO2. Using receiver operating characteristic curve inflection points for both P/F and A-a difference (area under the curve of 0.8 for both), patients with a P/F ratio less than 290 and an A-a difference of 100 mm Hg or greater were more likely to fail extubation (odds ratio, 9.2 and 8.7, respectively, p < 0.001). CONCLUSION: Blunt trauma patients with pulmonary contusion who are likely to fail extubation can be reliably identified using the readily available criteria of P/F ratio less than 290 and A-a difference of 100 mm Hg or greater.

Results of a focused scald-prevention program.

Scalds are a leading cause of burn injury for young children. A focused prevention program was developed in the zip code accounting for the majority of scald burns. This study investigated the effect of the program. Families in the high-risk area were identified at clinics, community centers, and schools. Parent workshops and home visits were the interventions used. A pretest was administered at the workshop to measure baseline knowledge. A post-test was administered at either the home visit or by telephone to measure change in knowledge. A survey was used to measure baseline scald risks in the home. Home visits were used to reinforce information from workshops, evaluate the home environment, and assist parents to make environmental changes. Changes to the home environments were made, with antiscald devices installed in the shower, sink, or bathtub depending on parent preference. The survey was repeated on a follow-up home visit to determine whether parents adhered to environmental changes and safety practices. The postmeasurements were performed from 6 to 12 months after the initial measurement. More than 900 parents attended the initial workshops, and 173 consented to participate in the follow-up study and took the pretest. Of these, 62 completed the post-test, and 48 participated in a home visit. The mean pretest score was 72 +/- 1%, and mean post-test score was 85 +/- 1% (P < .01). The initial home visit surveys revealed an average of 7 +/- 2 scald risks per household, whereas follow-up surveys showed an average of 2 +/- 1 risks (P < .01). Antiscald devices were installed in 37 households on the initial visit and remained in place and functioning in 22 households (60%) on the follow-up visit. Before the focused prevention program, the admission rate from the target zip code was 137 per 100,000 children ages 0 to 5 years. After the intervention, there was a greater than 2-fold reduction, to 59 per 100,000 (P < .01). In addition, there were no new scald burns in the homes in which the focused prevention program took place. This study demonstrates that a focused burn-prevention program can identify high-risk groups, decrease the number of scald risks per home, and decrease the rate of scald burns in the population. This straightforward program could be used to intervene in high-risk groups in other communities.

Developing a focused scald-prevention program.

Scalds account for a high percentage of burn injuries in young children. The purpose of this project was to use a formative evaluation process to design a pilot scald-prevention program for a high-risk population. The burn registry and U.S. Census were used to define a high-risk population. A total of 53 children younger than age 6 were admitted to a local burn center with scalds during a 4-year period. Cooking or food accounted for 84% of these injuries. A total of 21% of the patients resided in one zip code, representing an incidence rate of 23 per 100,000, which was statistically significant. Focus group meetings were conducted with parents in this zip code. They were queried about scald injury knowledge, prevention practices, and attitudes toward interventions. A prevention program was designed based on the findings. Workshops are conducted with high-risk groups in the zip code. Attendees consent to a home visit where prevention practices are assessed and taught. A pre/post test and home risk assessment survey is used to measure change. The Burn Registry, U.S. Census, and focus groups were complimentary formative evaluation measures that assisted in developing a targeted scald prevention project.
