Palliative Emergency General Surgery.

Acute care surgeons encounter patients experiencing surgical emergencies related to advanced malignancy, catastrophic vascular events, or associated with multisystem organ failure. The acute nature is a factor in establishing a relationship between surgeon, patient, and family. Surgeons must use effective communication skills, empathy, and a knowledge of legal and ethical foundations. Training in palliative care principles is limited in many medical school and residency curricula. We offer examples of clinical situations facing acute care surgeons and discuss evidence-based recommendations to facilitate successful treatment and outcomes.

A Comprehensive Spinal Cord Injury Treatment Protocol Improves Outcomes and Decreases Complications.

BACKGROUND: Spinal cord injury (SCI) is a devastating event with a complicated recovery. Through the use of an interdisciplinary team a comprehensive care plan was developed, utilizing all available best practices, to prevent secondary complications. Previous work has shown the benefit of single system protocols or interventions. This study aimed to assess changes in outcomes after implementation of a comprehensive protocol. MATERIAL AND METHODS: This was a retrospective cohort study performed at an ACS Level I trauma center. It was based on data abstract from the institutions trauma registry over a 10 year period. Patients with quadriplegia after a traumatic injury were included. Data on hospital outcomes and complications was collected and compared before and after the use of the Spinal cord injury protocol. RESULTS: 58 patients were evaluated. Overall, there was a reduction in complications after the implementation, with significant reductions in pneumonia (47% vs 16%; P = .02) and decubitus ulcers (47% to 11%; P = .005). ICU length of stay decreased by 7 days and hospital length of stay decreased 13 days. There was no difference in mortality. Hospital costs also decreased a mean of $42,000. CONCLUSIONS: A comprehensive SCI protocol can reduce secondary complications in quadriplegic patients. This study found significant decreases in pneumonia and decubitus ulcer rates after implementation of the protocol. Lengths of stay and cost were also significantly reduced. Future research using comprehensive SCI protocols is needed to further assess its effects on outcomes for this specific patient population. Similar centers should consider adoption of comprehensive SCI protocols.

Will Protective Innovations Like the "Airway Box" Become Routine Practice After the Pandemic?: An Opinion Survey.

Background Tracheal intubation carries an elevated risk of exposure to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) due to the generation of aerosols containing high concentrations of the virus. An airway box was designed to mitigate the exposure of healthcare professionals performing intubations. Aim We evaluated usability and sustainability in the routine practice of the "airway box" as a protective device during high-risk airway procedures.  Materials and methods After institutional review board approval, clinicians were educated on using the device through simulation, intranet learning modules, and emailed resources. The airway box was made available in the emergency department, critical care units, perioperative area, and operating rooms. QR codes affixed to the box, emailed, and displayed in common areas provided easy access to complete a REDcap survey (Vanderbilt University Nashville, USA) eliciting providers' experience. Data was collected and analyzed between April 1 and July 31, 2020, on REDcap, and the results were analyzed. Results 687 emergent intubations took place. 232 were performed by anesthesiologists, 315 by emergency department providers, and 140 by critical care specialists. 39 surveys were completed, 29 from intubations in the operating room, three from the critical care units, five from interventional radiology suites, and two perioperatively. Providers found the device to be readily available, with a score of 4.51/5, and the majority of providers, 60%, found the device easy to use, rating it either a 4 or 5 out of 5. Providers acquired a mean Mallampati score of 1.75 and 1.40 mean laryngoscopic grade view. Conclusion Intubation boxes may effectively mitigate high-risk viral exposure during airway procedures. Survey responses show that devices were easy to use and did not significantly affect visualization of the airway. Similar to mask use, enclosure devices in clinical practice could become a vital part of medical protective equipment even after the SARS-CoV-2 pandemic if they are effectively implemented.

Adjusted vs Total Body Weight-Based Dosing of Sedation and Analgesia Used in the Intensive Care Unit.

Background: The purpose of this study was to evaluate if dosing fentanyl, dexmedetomidine, and propofol based on ideal or adjusted vs actual weight in patients would decrease overall opioid and sedative use. Methods: This was a retrospective chart review comparing adjusted vs actual weight-based dosing protocol of mechanically ventilated (MV) intensive care unit (ICU) adult patients who required fentanyl and either propofol or dexmedetomidine. Results: A total of 261 patients were included in which 101 patients were in the actual weight group and 160 patients were in the adjusted weight group. Total doses per MV day of fentanyl was 1042 ± 1060 µg in the actual weight group vs 901 ± 1025 µg in the adjusted weight group (P = .13). Total doses per MV day of midazolam was 20 ± 19 mg in the actual group vs 15 ± 19 mg adjusted group (P = .02). Average MV days was 8.2 vs 7.1 days, ICU length of stay was 10.6 vs 9.4 days, and self-extubation rates were 17.8% vs 4.4% in the actual group and adjusted group, respectively. Conclusion: Total midazolam doses per MV day were lower in the adjusted group. No significant change was seen in MV days, ICU length of stay, or self-extubation rates.

Guidance for Healthcare Providers Managing COVID-19 in Rural and Underserved Areas.

Coronavirus disease 2019 (COVID-19), which is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has ravaged many urban and high-density areas in the USA. However, rural areas (despite their low population density) may be especially vulnerable to poor outcomes from COVID-19, owing to limited healthcare infrastructure, long distances to advanced health care, and population characteristics (e.g., high tobacco use, hypertension, obesity, older age). A panel of experts who are actively engaged in treating and managing COVID-19 at a rural academic center was convened to address this topic. In this commentary, we provide readers with some specific issues faced by rural healthcare providers and offer guidance in overcoming these challenges. This guidance includes alternative ventilator strategies, personal protective equipment (PPE), and common therapeutic options.

Management of penetrating intraperitoneal colon injuries: A meta-analysis and practice management guideline from the Eastern Association for the Surgery of Trauma.

BACKGROUND: The management of penetrating colon injuries in civilians has evolved over the last four decades. The objectives of this meta-analysis are to evaluate the current treatment regimens available for penetrating colon injuries and assess the role of anastomosis in damage control surgery to develop a practice management guideline for surgeons. METHODS: Using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology, a subcommittee of the Practice Management Guidelines section of EAST conducted a systematic review using MEDLINE and EMBASE articles from 1980 through 2017. We developed three relevant problem, intervention, comparison, and outcome (PICO) questions regarding penetrating colon injuries. Outcomes of interest included mortality and infectious abdominal complications. RESULTS: Thirty-seven studies were identified for analysis, of which 16 met criteria for quantitative meta-analysis and included 705 patients considered low-risk in six prospective randomized studies. Seven hundred thirty-eight patients in 10 studies undergoing damage control laparotomy and repair or resection and anastomosis (R&A) were included in a separate meta-analysis. Meta-analysis of high-risk patients undergoing repair or R&A was not feasible due to inadequate data. CONCLUSIONS: In adult civilian patients sustaining penetrating colon injury without signs of shock, significant hemorrhage, severe contamination, or delay to surgical intervention we recommend that colon repair or R&A be performed rather than routine colostomy. In adult high-risk civilian trauma patients sustaining penetrating colon injury, we conditionally recommend that colon repair or R&A be performed rather than routine colostomy. In adult civilian trauma patients sustaining penetrating colon injury who had damage control laparotomy, we conditionally recommend that routine colostomy not be performed; instead, definitive repair or delayed R&A or anastomosis at initial operation should be performed rather than routine colostomy. LEVEL OF EVIDENCE: Systematic review/meta-analysis, level III.

Longitudinal Ultrasound Curriculum Incorporation at West Virginia University School of Medicine: A Description and Graduating Students' Perceptions.

OBJECTIVES: Sonography is a clinical tool being incorporated in multiple medical specialties with evidence of improved patient care and cost. Some schools have begun implementing ultrasound curricula. We hope to build upon that foundation and provide another potential framework of incorporation. There are several barriers, including curricular space, equipment and physical space, adequate faculty, and performing assessment. METHODS: At West Virginia University, we began a longitudinal ultrasound curriculum in 2012 with incorporation of didactic and practical sessions into gross anatomy, our systems-based second-year curriculum, physical diagnosis course, and clinical rotations. We included both written and practical assessment from the onset. After the initial 4 years, the first graduates were surveyed on their perceptions of the curriculum. Responses were correlated with specialty choice and clinical campus site. RESULTS: Based on our survey (90% response rate), students felt sonography was useful for anatomical understanding and patient care. Overall, 93% of our respondents reviewed the curriculum favorably. Qualitative feedback was very positive, with students desiring more ultrasound education and more required components, specifically in clinical rotations. CONCLUSIONS: Based on these results, some changes have already been implemented, including decreased student-to-instructor ratios, more open scan time, and more required components. The breadth of formal assessment has increased. Multiple pilot programs for clinical rotations are being developed. There is an ongoing need for faculty development and continued assessment of ultrasound competency.

Antifibrinolytics in a rural trauma state: assessing the opportunities.

BACKGROUND: Tranexamic acid (TXA) has demonstrated improved mortality among trauma patients. However, recent evidence from urban US trauma centers has failed to show a benefit among the civilian population. TXA in rural states has not been evaluated. This study aimed to evaluate the current use of TXA in the rural trauma population. METHODS: A retrospective observational review at a level 1 trauma center based in a rural environment. Records were reviewed for TXA indications. TXA indication was defined as: systolic blood pressure <90 mm Hg, blood transfusion, or with a clinical concern for ongoing bleeding. Patients were ineligible if the time since injury was >3 hours. RESULTS: 400 patients were evaluated. 54% of patients met indications for TXA. 14% of these received TXA. 30.4% with an indication for TXA were ineligible due to arrival beyond 3 hours from time of injury. 135 patients arrived as transfers, 265 from the scene. There was no difference in TXA indications between scene and transfers (73 vs 144, p=1). Transfers were more likely to arrive beyond the 3-hour window (59 vs 7, p=0.001). Mortality for patients treated with TXA was 12.5%. This was not significantly different from patients not treated with TXA (19%). DISCUSSION: In a rural system, long transfers exclude most patients from treatment with TXA. A multicenter rural trauma center study will be needed to better define the optimal use of TXA in rural populations. LEVEL OF EVIDENCE: Level IV data: therapeutic/care management.

Major Trauma and the Elder West Virginian: A Six Year Review at a Level I Trauma Center.

BACKGROUND: Trauma was the seventh leading cause of death for persons 65 and older in West Virginia (WV) in 2010. In 2007, fatality rates for both accidental falls and motor vehicle crashes were higher in West Virginia than the nation as a whole. US Census Data from 2010 showed WV to have one of the oldest median ages in the nation (surpassed by Maine and Vermont) and currently 16% of the population of WV is over 65 years of age. METHODS: This is a retrospective observational study of data extracted from the John Michael Moore Trauma Center (JMMTC) trauma registry for the time period of January 1, 2009 to December 31, 2014. RESULTS: There were 3,895 patients, aged 65 years or older, treated at the Jon Michael Moore Trauma Center in Morgantown, WV during the study time period. Accidents accounted for 98.6% of the injuries. The elderly were most commonly injured in their place of residence (59.8%). The top two mechanisms of injury were falls (75.2%) and motor vehicular crashes (13.9%). Frequently, disposition from the Emergency Department was to a higher level of care: Intensive Care Unit (32.3%) and Step-down Unit (21.2%). The most common serious injuries were intracranial hemorrhage (40.0%), lower extremity fractures (38.1%), and spine fracture (26.0%). The average hospital stay was 5.6 days and the average ICU stay was 3.2 days. Hospital discharge dispositions frequently resulted in care out of the home; skilled nursing facility (22.0%), rehabilitation facility (15.5%), morgue/funeral home (6.6%), and long-term residential care facility (5.7%). The most common pre-existing medical conditions were hypertension (71.9%), diabetes mellitus (29.3%), chronic obstructive pulmonary disease (19.5%), and dementia (18.8%). CONCLUSION: Elder West Virginians most frequently are injured in falls and motor vehicular crashes. Pre-existing medical conditions are very common. Trauma in the elderly creates a significant burden on the patient, their families, and on the health care system in West Virginia. Injury prevention interventions have the potential to diminish the impact of trauma on elder West Virginians.

Ruptured Splenic Artery Aneurysm: Rare Cause of Shock Diagnosed with Bedside Ultrasound.

Splenic artery aneurysm rupture is rare and potentially fatal. It has largely been reported in pregnant patients and typically not diagnosed until laparotomy. This case reports a constellation of clinical and sonographic findings that may lead clinicians to rapidly diagnose ruptured splenic artery aneurysm at the bedside. We also propose a rapid, but systematic sonographic approach to patients with atraumatic hemoperitoneum causing shock. It is yet another demonstration of the utility of bedside ultrasound in critically ill patients, specifically with undifferentiated shock.

Do we glow? Evaluation of trauma team work habits and radiation exposure.

BACKGROUND: Health care workers' potential exposure to ionizing radiation has increased. Annual radiation exposure limit for the general public per US Nuclear Regulatory Commission is 100 mrem (1 mSv). The whole-body annual occupational radiation exposure limit is 5,000 mrem (50 mSv). Studies have been done to evaluate patient radiation exposure. To date, there has been no study to evaluate the radiation exposure of trauma team members or evaluate their behaviors and attitudes. METHODS: Forty primary providers (residents, physician assistants) rotating on the trauma service at an American College of Surgeons Level 1 trauma center participated. Dosimeters were worn by participants, and the radiation doses were measured monthly. A survey detailing the frequency of involvement in radiographic studies, use of protective equipment, and knowledge of education programs was completed monthly. RESULTS: The range of radiation measured was 1 mrem to 56 mrem, with an average effective dose of 10 mrem per month. Thirty-two (80%) of 40 reported daily exposure to x-rays and 28 (70%) of 40 to computed tomographic scans. Thirty-four (85%) of 40 reported that they never or seldom wore lead apron in trauma bay as opposed to 1 (3%) of 40 who failed to wear it during fluoroscopy. Twenty (50%) reported that an apron was not available, while 20 (50%) reported that it was too hot or did not fit. Thirty-nine (97%) of 40 reported that they received training in radiation safety. CONCLUSION: Despite inconsistent use of protective equipment by resident staff, the actual radiation exposure remains low. Hospitals should be sure lead aprons and collars are available. Additional education concerning the availability of programs during pregnancy is needed. LEVEL OF EVIDENCE: Epidemiologic study, level III.

The M33 chemokine receptor homolog of murine cytomegalovirus exhibits a differential tissue-specific role during in vivo replication and latency.

M33, encoded by murine cytomegalovirus (MCMV), is a member of the UL33 homolog G-protein-coupled receptor (GPCR) family and is conserved across all the betaherpesviruses. Infection of mice with recombinant viruses lacking M33 or containing specific signaling domain mutations in M33 results in significantly diminished MCMV infection of the salivary glands. To determine the role of M33 in viral dissemination and/or infection in other tissues, viral infection with wild-type K181 virus and an M33 mutant virus, DeltaM33B(T2), was characterized using two different routes of inoculation. Following both intraperitoneal (i.p.) and intranasal (i.n.) inoculation, M33 was attenuated for infection of the spleen and pancreas as early as 7 days after infection. Following i.p. inoculation, DeltaM33B(T2) exhibited a severe defect in latency as measured by a diminished capacity to reactivate from spleens and lungs in reactivation assays (P < 0.001). Subsequent PCR analysis revealed markedly reduced DeltaM33B(T2) viral DNA levels in the latently infected spleens, lungs, and bone marrow. Following i.n. inoculation, latent DeltaM33B(T2) viral DNA was significantly reduced in the spleen and, in agreement with results from i.p. inoculation, did not reactivate from the spleen (P < 0.001). Furthermore, in vivo complementation of DeltaM33B(T2) virus replication and/or dissemination to the salivary glands and pancreas was achieved by coinfection with wild-type virus. Overall, our data suggest a critical tissue-specific role for M33 during infection in the salivary glands, spleen, and pancreas but not the lungs. Our data suggest that M33 contributes to the efficient establishment or maintenance of long-term latent MCMV infection.
