AbstractBackgroundThe aim is to study the safety of Angioembolization on long-term sexual function and quality of life.MethodsIRB approval was gained to review the prospectively collected trauma database as well as prospective questionnaires of patients at least 1 year out from pelvic fractures that occurred between 1996 and 2009. Surveys included the SF36v2, Female Sexual Function Index and the International Index of Erectile Function. Values for each domain were compared between patients treated with AE and 2:1 case-matched control patients as well as between the national norms. Values are presented as percentages or means with 95 % CI. P < 0.05 was considered statistically significant.ResultsThirty Seven cases and 74 matched controls were identified. 42 patients completed the survey. There were 13 cases (12 males), and 29 controls (22 males). There was a higher ISS (Injury Severity Score) (32 vs 27; p = 0.048) in the cases, but no difference in pelvic AIS (Abbreviated Injury Severity Score) (3 vs 3). Both groups scored similarly in the SF36 in all domains, but the entire cohort scored lower than the national norms in the physical functioning (41.9 (37.8–46.0) vs50), role physical (40.9 (36.2–45.7) vs50), body pain 43.8 (40.7–46.9) vs50), role emotional 46.3 (42.8–49.8) vs50), and physical composite score (42.1 (38.0–46.3) vs50). All domains of the sexual function in both questionnaires showed significant impairment in our cohort compared with norms. Male cases had similar scores to the controls.ConclusionPelvic fractures portend a worse long-term QOL and sexual function than the general population. AE, however, does not have an additive affect to these indices.

AbstractBackgroundRib fractures are common after chest wall trauma. For patients with flail chest, surgical stabilization is a promising technique for reducing morbidity. Anatomical difficulties often lead to an inability to completely repair the flail chest; thus, the result is partial flail chest stabilization (PFS). We hypothesized that patients with PFS have outcomes similar to those undergoing complete flail chest stabilization (CFS).MethodsA prospectively collected database of all patients who underwent rib fracture stabilization procedures from August 2009 until February 2013 was reviewed. Abstracted data included procedural and complication data, extent of stabilization, and pulmonary function test results.ResultsOf 43 patients who underwent operative stabilization of flail chest, 23 (53 %) had CFS and 20 (47 %) underwent PFS. Anterior location of the fracture was the most common reason for PFS (45 %). Age, sex, operative time, pneumonia, intensive care unit and hospital length of stay, and narcotic use were the same in both groups. Total lung capacity was significantly improved in the CFS group at 3 months. No chest wall deformity was appreciated on follow‐up, and no patients underwent additional stabilization procedures following PFS.ConclusionDespite advances in surgical technique, not all fractures are amenable to repair. There was no difference in chest wall deformity, narcotic use, or clinically significant impairment in pulmonary function tests among patients who underwent PFS compared with CFS. Our data suggest that PFS is an acceptable strategy and that extending or creating additional incisions for CFS is unnecessary.

ABSTRACT Differential diagnosis of asymptomatic bacteriuria (ASB) and urinary tract infection (UTI) is based on the presence of diverse symptoms, including fever (≥38.5°C), rigors, malaise, lethargy, flank pain, hematuria, suprapubic discomfort, dysuria, and urgent or frequent urination. There is consensus in the medical community that ASB warrants antibiotic treatment only for patients undergoing urological procedures that lead to mucosal bleeding, catheterized individuals whose ASB persists for more than 48 h after catheter removal, and pregnant women. Pyuria is associated with UTI and implicates host immune responses via release of antibacterial effectors and phagocytosis of pathogens by neutrophils. Such responses are not sufficiently described for ASB. Metaproteomic methods were used here to identify the pathogens and evaluate molecular evidence of distinct immune responses in cases of ASB compared to UTI in elderly patients who were hospitalized upon injury. Neutrophil-driven inflammatory responses to invading bacteria were not discernible in most patients diagnosed with ASB compared to those with UTI. In contrast, proteomic urine analysis for trauma patients with no evidence of bacteriuria, including those who suffered mucosal injuries via urethral catheterization, rarely showed evidence of neutrophil infiltration. The same enzymes contributing to the synthesis of leukotrienes LTB 4 and LTC 4 , mediators of inflammation and pain, were found in the UTI and ASB cohorts. These data support the notion that the pathways mediating inflammation and pain in most elderly patients with ASB are not quantitatively different from those seen in most elderly patients with UTI and warrant larger clinical studies to assess whether a common antibiotic treatment strategy for elderly ASB and UTI patients is justified.

Almost 50% of trauma‐related fatalities within the first 24 hours of injury are related to hemorrhage. Improved survival in severely injured patients has been demonstrated when massive transfusion protocols are rapidly invoked as part of a therapeutic approach known as damage control resuscitation (DCR). DCR incorporates the early use of plasma to prevent or correct trauma‐induced coagulopathy. DCR often requires the transfusion of plasma before determination of the recipient's ABO group. Historically, group AB plasma has been considered the “universal donor” plasma product. At our facility, the number of AB plasma products produced on an annual basis was found to be inadequate to support the trauma service's DCR program. A joint decision was made by the transfusion medicine and trauma services to provide group A thawed plasma (TP) for in‐hospital and prehospital DCR protocols. A description of the implementation of group A TP into the DCR program is provided as well as outcome data pertaining to the use of TP in trauma patients.

AbstractBackgroundRib fracture stabilization has become a more accepted practice although stabilization of the most cephalad ribs presents a unique challenge. We present our experience with use of a 90° drill and screwdriver to bridge these difficult rib fractures.MethodsThis retrospective review included patients who underwent rib fracture stabilization from August 1, 2009, through September 30, 2012. Patients were divided into two groups: those whose procedure used the 90° device and those that did not. Data were compared using standard statistical analysis and reported as percentages and medians [interquartile ranges]. P values <0.05 were considered significant.ResultsWe identified 89 patients: 29 (33 %) had 90° devices used and 60 (67 %) did not. There were no differences between groups in age, sex, Trauma‐Related Injury Severity Score, the presence of flail chest, occurrence of pneumonia, and intensive care unit or hospital length of stay. The Injury Severity Score was higher in the 90° group (22 vs. 16; P = 0.03). The highest rib stabilized was different between the 2 groups (3 [2–5] vs. 5 [2–9]; P = 0.001), with more third rib stabilizations in the 90° group (38 vs. 20 %; P = 0.04) as well as more total number of ribs fixed (5 vs. 4; P = 0.001). There was no difference in operative time between the 2 groups.ConclusionsThe surgical reach for rib fracture stabilization has been extended with use of a 90° drill and screwdriver. High fractures under the scapula where access is technically challenging can be stabilized without prolonging operative times.

AbstractBackgroundBotulinum toxin A (BTX) confers flaccid paralysis and pain modulation when injected into a muscle. We hypothesized that long‐term paralysis of the abdominal wall musculature (i.e., chemical component paralysis, CCP) would benefit incisional hernia repair (IHR) by decreasing postoperative pain, the use of opioid analgesia, and thus opioid‐related side effects.MethodsAdult patients who underwent elective IHR with preoperative CCP (n = 22) were compared to concurrent matched controls (n = 66, 1:3 ratio) based on age (±5 years), sex, body mass index (±5 kg/m2), history of hernia recurrence (0 vs. ≥1), and type of repair (open vs. laparoscopic). BTX was injected under ultrasonographic guidance into the transversus abdominis and internal and external oblique muscles at three sites bilaterally (300 units total).ResultsPatients who underwent IHR with CCP used significantly less opioid analgesia (mean ± SD morphine equivalents) when compared to controls on hospital days (HDs) 2 and 5: HD2, 48 ± 27 versus 87 ± 41; HD5, 17 ± 16 versus 48 ± 45. Likewise, CCP patients reported significantly less pain (visual analogue scale 1–10) when compared to controls on HD2 (5.2 ± 1.5 vs. 6.8 ± 2) and HD4 (3.6 ± 1.2 vs. 5.2 ± 1.9): all p < 0.007 (Bonferroni adjusted). There was no difference in postoperative complications (surgical site, 9 vs. 14 %), opioid‐related adverse events (ileus 5 vs. 5 %), hospital stay (4 ± 3 vs. 3 ± 2 days), or hernia recurrence (18 months mean follow‐up: 9 vs. 9 %).ConclusionsDespite similar multimodality treatment of postoperative pain after IHR, patients who underwent CCP required significantly less opioid analgesia and reported less pain.

AbstractBackgroundThe aim of the present study was to obtain data regarding the timing of anticoagulation resumption in patients with spontaneous rectus sheath hematomas (RSH).Patients and methodsThe study is based on review of patients receiving anticoagulation medication who were diagnosed with a spontaneous RSH (traumatic and iatrogenic excluded) between 14 July 1997 and 17 March 2012.ResultsThere were 156 patients (37 % male; aged 73 ± 13 years) with an average body mass index of 29 ± 7 (procedure group 28 ± 6). Anticoagulants included coumadin (64 %), intravenous heparin (21 %), aspirin (8 %), and others (7 %). An intervention was needed in 29 (19 %) of the patients (5 % operative; 16 % embolization). Sixty‐two percent of patients had their anticoagulation restarted during their hospitalization, with a median re‐initiation time of 4 days after RSH diagnosis (range 2–8 days). Timing of anticoagulant resumption did not differ regardless of the need for intervention (3 vs. 4 days). The complication rate was 19 % (42 % in the procedure group, none specific to the procedure), with the most common being acute renal failure (n = 8; 5 %), death (n = 8; 5 %), and thrombotic events (n = 5; 3 %). After resumption of anticoagulation, two patients suffered enlargement of their RSH, both 2 days after resumption.ConclusionsIntervention to control hemorrhage was unnecessary in the majority of patients with RSH. In those with resumption of anticoagulation, the majority of patients were safely restarted by day 4. Even though complications secondary to anticoagulation were few, thrombotic complications outnumbered bleeding complications, suggesting that anticoagulation was withheld for too long after RSH diagnosis.

BackgroundThe rapid reversal of warfarin in the setting of traumatic brain injury (TBI) has been associated with improved outcomes. Until now, remote reversal of hypocoagulable states has not been possible in the prehospital environment. This manuscript describes the development and analysis of a prehospital plasma transfusion protocol to reverse warfarin at the earliest possible moment after TBI.Study Design and MethodsA retrospective review of all TBI patients receiving plasma transfusion(s) in the prehospital environment for warfarin reversal between February 2009 and September 2010 was conducted. Thawed plasma was carried on every air ambulance flight centered at the main campus.ResultsA total of 2836 flights carried over 2500 units of thawed plasma throughout the study period. During this time, 16 patients received prehospital plasma resuscitation, five of who were on warfarin with a concurrent TBI. The median Injury Severity Score was 17 (8.5‐27.5) with a median Glasgow Coma Score of 13 (8‐15) and a mortality rate of 40%. A median of 2 (1.5‐2.0) units of thawed plasma and 0 (0‐0) units of RBCs were transfused en route. The pretransfusion point‐of‐care international normalized ratio improved from 3.1 (2.3‐4.0) to 1.9 (1.3‐3.6) upon trauma center admission (serum sample). One hundred percent of the transported, but unused, thawed plasma underwent subsequent transfusion prior to expiration.ConclusionsRemote prehospital plasma transfusions effectively reverse anticoagulation secondary to warfarin administration in TBI patients. It is feasible to transfuse thawed plasma in the prehospital setting via remote damage control techniques without increasing waste. Prospective studies are needed to determine if this practice can improve outcomes in this population.

We present the midterm clinical outcomes and predictors of balloon angioplasty and stent placement in atherosclerotic femoropopliteal (FP) arterial disease. Between January 2002 and August 2006, 155 patients (men = 56%; 71.4 ± 10.5 years) underwent 171 FP angioplasty or stent for claudication (n = 82, 54%) or critical limb ischemia ([CLI] n = 70, 46%). Follow-up was obtained through September 30, 2009. The average follow-up was 3.25 ± 1.73 years. In claudicants versus CLI, the 12-month patency for TransAtlantic InterSociety Consensus II (TASC II) classification (TASC A/B) was 93% versus 80%, respectively, and TASC C/D 83% versus 80%. At 3 years, TASC A/B was 82% versus 80%, respectively, and TASC C/D was 56% versus 80%, respectively. The predictor of clinical failure in claudicants was chronic renal insufficiency (CRI) and in CLI, the predictor of amputation was hyperlipidemia.
