Intra-abdominal Pressure Monitoring During Negative Pressure Wound Therapy in the Open Abdomen.

INTRODUCTION: Negative pressure wound therapy (NPWT) is commonly used in open abdomen management, where there may be a simultaneous need for prevention of abdominal hypertension, tamponade of hemorrhage, and continuous fascial tension. The regional pressure dynamics of vacuum dressings are poorly understood. METHODS: Three duroc swine underwent mid-line laparotomy and application of vacuum open abdomen dressing, with and without sponge packing. Twenty-five catheters were placed throughout the abdomen to capture and record pressures in each quadrant as the vacuum system was ranged between (-75 mmHg to -200 mmHg pressure). Vital signs and ventilator pressures were measured and recorded concomitantly. RESULTS: No variations in ventilatory pressures or vital signs were observed with any setting. NPWT changed pressure in seven of seventy-five catheters (9%), five of which were related to abdominal packing. When data were grouped into abdominal wall, perihepatic, perisplenic, and deep abdominal regions, there was no significant change in abdominal pressure when packing was absent. With packing, only the abdominal wall region showed a pressure change, reaching a maximum of 20% of the set vacuum pressure. CONCLUSIONS: NPWT does only little to change the intraabdominal pressure, except in superficial locations in packed abdomens and does not appear to cause hemodynamic changes in a porcine open abdomen model. While NPWT may play an important role in fluid scavenging and fascial tensioning, there are likely to be few benefits or drawbacks specifically related to negative abdominal pressure in the deep abdomen.

The Case for Integrating Medical-Legal Partnerships Into Trauma Care.

INTRODUCTION: Medical-legal needs are health-harming adverse social conditions with a legal remedy. Medical-legal partnerships in primary care settings have been proposed to address these needs for at-risk patients already seeking medical care. Our hypothesis is that trauma patients represent a unique population that may be more likely to have baseline medical-legal needs. METHODS: A trauma-specific medical-legal needs survey was developed. Adult trauma patients who were able to give consent and were admitted to our urban Level I hospital were surveyed. Medical-legal needs were tabulated from the surveys. Those patients in the top decile of medical-legal needs were categorized as having a High Burden of medical-legal needs. Multivariate logistic regression was used to identify those independent risk factors for having a High Burden of medical-legal needs. RESULTS: A total of 566 participants completed the survey (78.2% response rate). The mean number of medical-legal needs for our population was 2.5 (SD = 3.1). 73% of our respondents had at least one medical-legal need. The most common needs were Housing (n = 229, 40%) and Education/Employment (n = 223, 39%). Older age (aOR = 3.01, 95% CI 1.2-8.1, P = 0.02), being separated or divorced (aOR = 4.25, 95% CI 1.2-14.0, P = 0.02), self perceived poor health (aOR = 8.4, 95% CI 2.61-26.86, P < 0.001), penetrating mechanism of injury (aOR = 2.52, 95% CI 1.22-5.2, P = 0.01), and having been admitted to the hospital for a longer period of time (aOR = 5.48, 95% CI 1.55-19.4, P = 0.008) were all independently associated with a High Burden of medical-legal needs. CONCLUSIONS: Trauma patients have a high baseline burden of medical-legal needs. Medical-legal partnerships embedded in trauma teams may offer an innovative strategy to help address long-term health outcomes in a highly vulnerable population that would not otherwise have contact with the healthcare system.

Measurement of Trauma Caregiver Stress: Validation of Heart rate variability in a Real-World Surgical Setting.

BACKGROUND: Acute stress is a potentially modifiable risk-factor that contributes to errors in trauma care. Research on stress mitigation is limited by the lack of a validated objective measure of surgeon stress. We sought to validate HRV in a real-world surgical setting by comparison to the Subjective Units of Distress Score (SUDS), and correlation with self-reported peak stress moments. METHODS: Attending and resident surgeons on the trauma team at a Level I Trauma Center wore armbands to measure HRV. Stress-associated blunting of HRV was analyzed using the standard deviation of N-N intervals (SDNN) and the root mean square of successive differences . Perceived stress was measured with the SUDS at random intervals and at perceived stress peaks. SUDS and HRV metrics were compared with a mixed effect regression model. Correlation between binned SUDS quartiles and HRV was evaluated. HRV at reported peak-stress moments were compared to shift baseline values. RESULTS: Twelve participants were monitored for 340 h, producing 135 SUDS responses and 65 peak-stress time points. Regression analysis demonstrated no correlation between HRV and SUDS. With a binned approach, decreased SDNN was associated with an elevated SUDS (P = 0.03). The self-identified peak-stress moments correlated with decreases in both SDNN and root mean square of successive differences (P = 0.02; P < 0.01). CONCLUSIONS: HRV by SDNN analysis correlated with heightened perceived stress, supporting its validity as a measure. However, the wide, frequent variation of HRV tracings within subjects, the sensitivity of HRV to of analytic technique, and the impact of confounders may limit its utility as an education or research tool. LEVEL OF EVIDENCE: V Diagnostic test.

Rectal Injury After Foreign Body Insertion: Secondary Analysis From the AAST Contemporary Management of Rectal Injuries Study Group.

BACKGROUND: Retained rectal foreign bodies are a common but incompletely studied problem. This study defined the epidemiology, injury severity, and outcomes after rectal injuries following foreign body insertion. METHODS: Twenty-two level I trauma centers retrospectively identified all patients sustaining a rectal injury in this AAST multi-institutional trial (2005-2014). Only patients injured by foreign body insertion were included in this secondary analysis. Exclusion criteria were death before rectal injury management or ≤48 h of admission. Demographics, clinical data, and outcomes were collected. Study groups were defined as partial thickness (AAST grade I) versus full thickness (AAST grades II-V) injuries. Subgroup analysis was performed by management strategy (nonoperative versus operative). RESULTS: After exclusions, 33 patients were identified. Mean age was 41 y (range 18-57), and 85% (n = 28) were male. Eleven (33%) had full thickness injuries and 22 (67%) had partial thickness injuries, of which 14 (64%) were managed nonoperatively and 8 (36%) operatively (proximal diversion alone [n = 3, 14%]; direct repair with proximal diversion [n = 2, 9%]; laparotomy without rectal intervention [n = 2, 9%]; and direct repair alone [n = 1, 5%]). Subgroup analysis of outcomes after partial thickness injury demonstrated significantly shorter hospital length of stay (2 ± 1; 2 [1-5] versus 5 ± 2; 4 [2-8] d, P = 0.0001) after nonoperative versus operative management. CONCLUSIONS: Although partial thickness rectal injuries do not require intervention, difficulty excluding full thickness injuries led some surgeons in this series to manage partial thickness injuries operatively. This was associated with significantly longer hospital length of stay. Therefore, we recommend nonoperative management after a retained rectal foreign body unless full thickness injury is conclusively identified.

Effects of night-float and 24-h call on resident psychomotor performance.

INTRODUCTION: Night-float work schedules were designed to address growing concerns of the affect of fatigue on resident psychomotor and cognitive skills after traditional 24-h call work schedules. Whether this transition has achieved these results is debatable. This study was designed to compare the psychomotor performance of general surgery residents on both work schedule types. We hypothesized that when measured with novel laparoscopic simulator tasks, residents on a 24-h call schedule would exhibit worse psychomotor performance compared with those on a night-float work schedule. METHODS: Nine general surgery residents at the post-graduate year (PGY) 2, 3, and 5 levels were recruited and trained on the Simbionix LAP Mentor Simulator (Simbionix, Cleveland, OH). Performance on two tasks was tested before and after a 24-h call work shift and a night-float shift. A survey assessing levels of work shift activity and fatigue were administered after all work shifts. RESULTS: There was no statistically significant difference in resident accuracy, speed of movement, economy of movement, and time to completion of the two simulation tasks. The only measures of work shift activity achieving statistically significant difference were number of patients seen and numbers of steps walked on call. There was no statistically significant difference in subjective evaluation of fatigue. CONCLUSIONS: In this study of general surgery residents, a statistically significant difference in psychomotor performance between residents working 24-h call shift versus a 12-h night-float shift could not be found. Psychomotor performance does not appear to suffer after a work shift. Additionally, post-shift subjective evaluations of fatigue are comparable regardless of shift type.

Trauma airway management: transition from anesthesia to emergency medicine.

BACKGROUND: Trauma airway management is commonly performed by either anesthesiologists or Emergency Physicians (EPs). OBJECTIVE: Our aim was to evaluate the impact of switching from one group of providers to the other, focusing on outcomes and complications. METHODS: Medical records were used to identify all patients during a 3-year period who were intubated emergently after traumatic injury. Before November 1, 2007, airway management was supervised by anesthesiologists, after that date airways were supervised by EPs. Complications evaluated included failure to obtain a secure airway, multiple attempts at airway placement, new or worsening hypoxia or hypotension during the peri-intubation period, bronchial intubations, dysrhythmia, aspiration with development of infiltrate on chest x-ray study within 48 h, and facial trauma. RESULTS: Of the 490 tracheal intubations, 250 were attended by EPs and 240 were attended by anesthesiologists. The groups were well matched with respect to age and sex, but the EP group treated more severely injured patients on average. Intubation was accomplished in one attempt 98.3% of the time in the anesthesia group; those requiring multiple attempts went on to need surgical airways 2.1% of the time. EPs accomplished intubation in one attempt 98.4% of the time, with an overall success rate of 96.8%; surgical airways were needed in 3.2% of patients. The complication rate was 18.3% for the anesthesia group and 18% for the EP group. There were no statistically significant differences between the EP and anesthesia groups with regard to complication rates, although the EP patients had a higher Injury Severity Score on average. CONCLUSIONS: EPs can safely manage the airways of trauma patients with rates of complication and failure comparable with those of anesthesiologists.

Watch and wait: conservative management of lower gastrointestinal bleeding.

BACKGROUND: Although indications for surgery in lower gastrointestinal bleeding (LGIB) are widely described, practice varies. This study was designed to assess outcomes of patients allowed to exceed traditional triggers for surgery because of LGIB. METHODS: This is a retrospective review of patients at an urban tertiary hospital over a 3-y period that had LGIB necessitating (99m)Tc-labeled red blood cell scintigraphy. Traditional indications for operative treatment of LGIB were defined as transfusion of >6U of packed red blood cells, hemodynamic instability, bleeding lasting >72h, and rebleeding after cessation of bleeding for >24h. RESULTS: One hundred ninety-four LGIB patients had scintigraphy during the period of study with 180 meeting inclusion criteria. Fifty-six (31%) patients had at least one operative indication, and 32 (60%) were managed nonoperatively without a mortality. There were two (8.3%) mortalities in those who had operative management, one of which was because of exsanguination. Eighteen (32%) patients who met operative criteria were unlocalized. CONCLUSIONS: Patients with LGIB can be safely managed nonoperatively, even when the bleed is unlocalized and traditional indications for surgery are met. Exsanguinations because of LGIB treated nonoperatively are rare except in patients deemed not to be surgical candidates.

Pregnancy in trauma-A Western Trauma Association algorithm.

BACKGROUND: The Western Trauma Association has undertaken publication of best practice clinical practice guidelines on multiple trauma topics. These guidelines are based on scientific evidence, case reports, and best practices per expert opinion. Some of the topics covered by this consensus group do not have the ability to have randomized controlled studies completed because of complexity, ethical issues, financial considerations or scarcity of experience. Care of the pregnant trauma patient is one of these clinically complex situations that is based on physiologic data, standard trauma care, trauma care experience, and outcomes. METHODS: Review of multiple evidence- based guidelines, case reports, and expert opinion were compiled and reviewed. RESULTS: The algorithm is attached with detailed explanation of each step, supported by data if available. CONCLUSION: Resuscitative and trauma care of the mother is the utmost priority. STUDY TYPE: Algorithm, expert opinion, consensus. LEVEL OF EVIDENCE: Diagnostic Tests/Criteria; Level III.

Sensitivity of computed tomography in detection of perirectal abscess.

Most patients with anorectal abscess are diagnosed clinically based on pain, erythema, warmth, and fluctuance. Some patients, however, present with subtle or atypical signs. CT is easily accessible and is commonly used for diagnosis and delineation of anorectal abscess. The purpose of this study is to determine the sensitivity of CT scan in detecting perirectal abscesses and to see if immune status impacts the accuracy of CT. A retrospective study was conducted to identify patients from 2000 to 2009 with International Classification of Diseases, 9th Revision code 566 (anal or rectal abscess). Patients included had a CT scan less than 48 hours before drainage. Patients with CT-positive abscess were compared with patients with CT-negative abscess. Patients were categorized as either immunocompetent or immunosuppressed based on documentation of diabetes mellitus, cancer, human immunodeficiency virus, or end-stage renal disease. One hundred thirteen patients were included in this study. Seventy-four (65.5%) were male and the average age was 47 years. Eighty-seven of 113 (77%) patients were positive on CT for anorectal abscess. Sixty of 113 (53%) patients included in this study were immunocompromised. CT missed 26 of 113 (23%) patients with confirmed perirectal abscess. Eighteen (69%) of these patients were immunocompromised compared with CT-positive patients (42 [48%], P = 0.05). The overall sensitivity of CT in identifying abscess was 77 per cent. CT lacks sensitivity in detecting perirectal abscess, particularly in the immunocompromised patient.

Concomitant bladder and rectal injuries: Results from the American Association for the Surgery of Trauma Multicenter Rectal Injury Study Group.

BACKGROUND: Combined traumatic injuries to the rectum and bladder are rare. We hypothesized that the combination of bladder and rectal injures would have worse outcomes than rectal injury alone. METHODS: This is an American Association for the Surgery of Trauma multi-institutional retrospective study from 2004 to 2015 traumatic rectal injury patients who were admitted to one of 22 participating centers. Demographics, mechanism, and management of rectal injury were collected. Patients who sustained a rectal injury alone were compared with patients who sustained a combined injury to the bladder and rectum. Multivariable logistic regression was used to determine if abdominal complications, mortality, and length of stay were impacted by a concomitant bladder injury after adjusting for cofounders. RESULTS: There were 424 patients who sustained a traumatic rectal injury, of which 117 (28%) had a combined injury to the bladder. When comparing the patients with a combined bladder/rectal injury to the rectal alone group, there was no difference in admission demographics admission physiology, or Injury Severity Score. There were also no differences in management of the rectal injury and no difference in abdominal complications (13% vs. 16%, p = 0.38), mortality (3% vs. 2%, p = 0.68), or length of stay (17 days vs. 21 days, p = 0.10). When looking at only the 117 patients with a combined injury, the addition of a colostomy did not significantly decrease the rate of abdominal complications (14% vs. 8%, p = 0.42), mortality (3% vs. 0%, p = 0.99), or length of stay (17 days vs. 17 days, p = 0.94). After adjusting for cofounders (AAST rectal injury grade, sex, damage-control surgery, diverting colostomy, and length of stay) the presence of a bladder injury did not impact outcomes. CONCLUSION: For patients with traumatic rectal injury, a concomitant bladder injury does not increase the rates of abdominal complications, mortality, or length of stay. Furthermore, the addition of a diverting colostomy for management of traumatic bladder and rectal injury does not change outcomes. LEVEL OF EVIDENCE: Level IV; prognostic/therapeutic.

July--as good a time as any to be injured.

BACKGROUND: Recent studies have suggested worse outcomes for patients hospitalized during the beginning of the academic calendar, though these findings have not been reproduced among trauma patients. This study compares outcomes of patients during the beginning of the academic year with those at the end of the academic year. METHODS: Retrospective trauma registry analysis of a large urban level I trauma center. Patients admitted during April/May (ENDYEAR group) or July/August (FRESH group) between 1998 and 2007 were included. Demographic and injury parameters were recorded, and outcomes compared including crude mortality, complication rate, length of stay (LOS), and intensive care unit LOS (ICU-LOS). TRISS methodology was used to evaluate risk-adjusted performance. RESULTS: Three thousand sixty-seven patients were included in the FRESH group and 3626 in the ENDYEAR group. Groups were similar in age (36 +/- 17 years and 36 +/- 17 years, p = 0.39) and mean Injury Severity Score (8 +/- 11 and 8 +/- 10, p = 0.85). There was no difference in LOS (4.6 +/- 0.2 days versus 4.5 +/- 0.2 days, p = 0.92) or ICU-LOS (5.6 +/- 0.2 days versus 5.3 +/- 0.2 days, p = 0.96). Per patient complication rates for the FRESH and ENDYEAR groups were 6% and 6% (p = 0.8), total complication rates were 12% and 13% (p = 0.07), and crude mortality was 7% and 6% (p = 0.11), respectively. FRESH and ENDYEAR groups had similar W-Statistics (1.0 and 1.2) and z scores (3.5 and 4.4). CONCLUSION: Outcomes were similar between patients injured at the beginning of the academic year compared with the end of the academic year. Our data does not support the concept of a July effect in level I trauma centers.

Fluoroquinolone-based versus ß-lactam-based regimens for complicated intra-abdominal infections: a meta-analysis of randomised controlled trials.

Complicated intra-abdominal infections (cIAIs) are common and confer significant morbidity, mortality and costs. In this era of evolving antimicrobial resistance, selection of appropriate empirical antimicrobials is paramount. This systematic review and meta-analysis of randomised controlled trials compared the effectiveness and safety of fluoroquinolone (FQ)-based versus ß-lactam (BL)-based regimens for the treatment of patients with cIAIs. Primary outcomes were treatment success in the clinically evaluable (CE) population and all-cause mortality in the intention-to-treat (ITT) population. Subgroup analyses were performed based on specific antimicrobials, infection source and isolated pathogens. Seven trials (4125 patients) were included. FQ-based regimens included moxifloxacin (four studies) or ciprofloxacin/metronidazole (three studies); BL-based regimens were ceftriaxone/metronidazole (three studies), carbapenems (two studies) or piperacillin/tazobactam (two studies). There was no difference in effectiveness in the CE (2883 patients; RR = 1.00, 95% CI 0.95-1.04) or ITT populations (3055 patients; RR = 0.97, 95% CI 0.94-1.01). Mortality (3614 patients; RR = 1.04, 95% CI 0.75-1.43) and treatment-related adverse events (2801 patients; RR = 0.97, 95% CI 0.70-1.33) were also similar. On subset analysis, moxifloxacin was slightly less effective than BLs in the CE (1934 patients; RR = 0.96, 95% CI 0.93-0.99) and ITT populations (1743 patients; RR = 0.94, 95% CI 0.91-0.98). Although FQ- and BL-based regimens appear equally effective and safe for the treatment of cIAIs, limited data suggest slightly inferior results with moxifloxacin. Selection of empirical coverage should be based on local bacterial epidemiology and patterns of resistance as well as antimicrobial stewardship protocols.

Extremity Vascular Injury Management: Good Outcomes Using Selective Referral to Vascular Surgeons.

Revascularization after extremity vascular injury has long been considered an important skill among trauma surgeons. Increasingly, some trauma surgeons defer vascular repair in response to training or practice patterns. This study was designed to document results of extremity revascularization surgery to evaluate trauma surgeon outcomes and judicious referral of more complex injuries to vascular surgeons (VAS). The trauma registry of an urban level I trauma center was used to identify all patients from 2003 to 2013 who underwent an early (<24 hours) procedure for urgent management of acute injury to extremity vessels. Patients were managed by trauma (TRA) versus VAS based on the practice pattern of the on-call trauma surgeon. Injury and outcome variables were recorded. Of 115 patients, 84 patients were revascularized by trauma and 31 vascular surgeries. There was no difference in complication rates or frequency of any type of complication associated with repairs performed by VAS or TRA. There were similar rates between the two groups for patients with multiple injuries, such as venous, bone or tendon, and nerve injury to the affected extremity. One VAS patient and two TRA patients developed compartment syndrome. In appropriately selected patients, trauma surgeons achieve good outcomes after revascularization of injured extremities.

Traumatic rectal injuries: Is the combination of computed tomography and rigid proctoscopy sufficient?

BACKGROUND: There are no clear guidelines for the best test or combination of tests to identify traumatic rectal injuries. We hypothesize that computed tomography (CT) and rigid proctoscopy (RP) will identify all injuries. METHODS: American Association for the Surgery of Trauma multi-institutional retrospective study (2004-2015) of patients who sustained a traumatic rectal injury. Patients with known rectal injuries who underwent both CT and RP as part of their diagnostic workup were included. Only patients with full thickness injuries (American Association for the Surgery of Trauma grade II-V) were included. Computed tomography findings of rectal injury, perirectal stranding, or rectal wall thickening and RP findings of blood, mucosal abnormalities, or laceration were considered positive. RESULTS: One hundred six patients were identified. Mean age was 32 years, 85(79%) were male, and 67(63%) involved penetrating mechanisms. A total of 36 (34%) and 100 (94%) patients had positive CT and RP findings, respectively. Only 3 (3%) patients had both a negative CT and negative RP. On further review, each of these three patients had intraperitoneal injuries and had indirect evidence of rectal injury on CT scan including pneumoperitoneum or sacral fracture. CONCLUSION: As stand-alone tests, neither CT nor RP can adequately identify traumatic rectal injuries. However, the combination of both test demonstrates a sensitivity of 97%. Intraperitoneal injuries may be missed by both CT and RP, so patients with a high index of suspicion and/or indirect evidence of rectal injury on CT scan may necessitate laparotomy for definitive diagnosis. LEVEL OF EVIDENCE: Diagnostic, level IV.

Contemporary management of rectal injuries at Level I trauma centers: The results of an American Association for the Surgery of Trauma multi-institutional study.

INTRODUCTION: Rectal injuries have been historically treated with a combination of modalities including direct repair, resection, proximal diversion, presacral drainage, and distal rectal washout. We hypothesized that intraperitoneal rectal injuries may be selectively managed without diversion and the addition of distal rectal washout and presacral drainage in the management of extraperitoneal injuries are not beneficial. METHODS: This is an American Association for the Surgery of Trauma multi-institutional retrospective study from 2004 to 2015 of all patients who sustained a traumatic rectal injury and were admitted to one of the 22 participating centers. Demographics, mechanism, location and grade of injury, and management of rectal injury were collected. The primary outcome was abdominal complications (abdominal abscess, pelvic abscess, and fascial dehiscence). RESULTS: After exclusions, there were 785 patients in the cohort. Rectal injuries were intraperitoneal in 32%, extraperitoneal in 58%, both in 9%, and not documented in 1%. Rectal injury severity included the following grades I, 28%; II, 41%; III, 13%; IV, 12%; and V, 5%. Patients with intraperitoneal injury managed with a proximal diversion developed more abdominal complications (22% vs 10%, p = 0.003). Among patients with extraperitoneal injuries, there were more abdominal complications in patients who received proximal diversion (p = 0.0002), presacral drain (p = 0.004), or distal rectal washout (p = 0.002). After multivariate analysis, distal rectal washout [3.4 (1.4-8.5), p = 0.008] and presacral drain [2.6 (1.1-6.1), p = 0.02] were independent risk factors to develop abdominal complications. CONCLUSION: Most patients with intraperitoneal injuries undergo direct repair or resection as well as diversion, although diversion is not associated with improved outcomes. While 20% of patients with extraperitoneal injuries still receive a presacral drain and/or distal rectal washout, these additional maneuvers are independently associated with a three-fold increase in abdominal complications and should not be included in the treatment of extraperitoneal rectal injuries. LEVEL OF EVIDENCE: Therapeutic study, level III.

Is informed consent in trauma a lost cause? A prospective evaluation of acutely injured patients' ability to give consent.

BACKGROUND: Obtaining informed consent in acute trauma patients is often impossible, forcing investigators to abandon important projects. To better understand the likelihood of -- and barriers to -- informed consent in trauma patients, we evaluated when and how consent is possible in acutely injured patients. STUDY DESIGN: Over a 7-month period, at a large, urban, adult Level I trauma center, we prospectively assessed each patient's ability to give hypothetical informed consent. Patients were considered consentable when they were alert, unintoxicated, and stable, with no prohibitive language barrier, or when a proxy (first-degree relative) was available. When consent was not feasible on arrival, we documented the reason and the time at which consent became possible, either by the patient or proxy. RESULTS: Of 1,328 consecutive trauma patients, 1,020 (77%) were candidates for consent (personal or proxy) within 30 minutes of arrival. Twenty-five percent of patients with hypotension in the resuscitation area were consentable, as were 31% of severely injured (Injury Severity Score>24) patients. Eight hours after injury, 88% of all patients were consentable, as were 60% of severely injured patients and 36% of patients with initial hypotension. Primary barriers to consent included brain injury or unspecified alteration in awareness (41%), intoxication (28%), shock (26%), language barrier (2%), or medication (3%). CONCLUSIONS: Although an overall majority of trauma patients are candidates for early informed consent, the likelihood of early consent is substantially lower in patients with severe injury or shock. Alternatives to individual informed consent may be necessary to advance the early care of acutely, severely injured patients.

Safety of early ambulation following blunt abdominal solid organ injury: A prospective observational study.

BACKGROUND: There is continued debate regarding the optimal period of bed-rest and in-hospital monitoring for non-operative management of solid organ injury following blunt trauma. METHODS: Single center, prospective, observational study of blunt solid organ injuries from 07/2014-02/2016, managed initially without surgical or angiographic intervention. Early ambulation was defined as ≤24 h. RESULTS: 79 patients met inclusion criteria, with 36 (45.6%) in the early ambulation group and 43 (54.4%) in the late ambulation group. There were zero complications in the early ambulation group, and three complications in the late ambulation group (complications, p = 0.246; further interventions, p = 0.498). Median ICU LOS was zero days and three days for early vs. late ambulation, p = 0.001. Median total LOS was two days and five days for early vs. late ambulation, p < 0.001. CONCLUSION: Early ambulation is safe in patients undergoing non-operative management of their solid organ injury, and may result in a reduced length of stay.

A pilot program to improve nursing and surgical intern collaboration: Lessons learned from a mixed-methods study.

BACKGROUND: Inter-professional collaboration is an integral component of a successful healthcare team. We sought to evaluate the impact of nursing student participation in a one-day intensive inter-professional education (IPE) training session with surgical interns on participant attitudes toward inter-professional collaboration. METHODS: Following IRB approval, pre and post IPE session survey responses were compared to determine the impact on participant attitudes toward inter-professional collaboration. Pre and post session semi-structured interviews were transcribed and analyzed to identify relevant themes. RESULTS: Surgical interns (n = 38) more than nursing students (n = 11), demonstrated a measurable improvement in attitude towards 'collaboration and shared education' (interns: median score pre = 26, post = 28, p = 0.0004; nursing student: median score pre = 27, post = 28, p = 0.02). Qualitative analysis of interviews identified major themes that supplemented this finding. CONCLUSION: An eight hour, one day IPE session has a positive impact on collaborative attitudes and supports the case for increased inter-professional education amongst interns and nursing students.

Outcomes Following Noncardiac Surgery in Patients with Ventricular Assist Devices: A Single-Center Experience.

the prevalence of ventricular assist devices (VADs) is increasing as advanced cardiac therapies progress. These patients commonly require non-cardiac surgical procedures (NCS), although data are scant regarding the safety, timing, and operations that may safely be performed. We aim to describe our experience with VAD patients undergoing NCS. We retrospectively reviewed records on patients who underwent NCS after VAD implantation between 2013 and 2015 at a single Joint Commission-accredited VAD institution. Data collection included demographics, ischemic cardiomyopathy or nonischemic cardiomyopathy, operative details, and perioperative anticoagulation management and outcomes. Seventy-two NCS were performed by general surgeons, thoracic surgeons, plastic surgeons, urologists, vascular surgeons, ENTs, and other services. Procedures were similarly varied, including video-assisted thoracoscopy with decortications or lung biopsy, tracheostomies, percutaneous endoscopic gastrostomies , exploratory laparotomies, and wound debridements and/or closures. The ten deaths in the study group were judged not to be directly related to NCS. Eleven cases had postoperative bleeding and two cases had postoperative thrombosis, including one pump thrombosis. Based on our results, VAD is not an absolute contraindication to NCS, and a variety of NCS procedures can safely be performed. Further study should focus on quantifying and mitigating the risk that VADs bring to NCS.
