Narcotic Consumption Analysis among Severely Injured and Advanced Aged Trauma Patients.

BACKGROUND: Multimodal pain management has been shown to be effective in treating pain in acutely injured trauma patients. Our community-based, level 1 trauma center previously published in 2022 the efficacy of implementing multimodal pain control (MMPC) protocol in our inpatient trauma population which decreased the use of opioids while maintaining similar pain control. The MMPC group had a trend toward higher age and was significantly less injured. We hypothesize MMPC will reduce opioid consumption in both the advanced aged and more severely injured trauma populations while still providing adequate pain control. METHODS: Defined by the year of admission, MMPC and physician managed pain control (PMPC) were compared in both advanced age groups and between the severely injured groups. The advanced age group included patients ≥55 years old. The severely injured group included ≥18 years old with ≥15 ISS. Primary outcomes were total opioid utilization per day, calculated in morphine milliequivalents (MME), and median daily pain scores. RESULTS: For the severely injured population, the MMPC group showed a 3-fold decrease in opioid use (30 MME/d vs 90.3 MME/d, P < .001) and lower pain scores (5/10 vs 6/10, P < .001) than the PMPC group. In the advance age group, there was no significant difference between MMPC and PMPC groups in opioid use (P = .974) or pain scores (P = .553). CONCLUSION: MMPC effectively reduces opioid consumption in a severely injured patient population while simultaneously improving pain control. Advanced age trauma patients can require complex pain management solutions and future research to determine their needs is recommended.

Prospective derivation and validation of a NECROtizing Soft tissue InfectionS (NECROSIS) score: An EAST multicenter trial.

BACKGROUND: Although several risk indices have been developed to aid in the diagnosis of NSTIs, these instruments suffer from varying levels of reproducibility and failure to incorporate key clinical variables in model development. The objective of this study was to derive and validate a clinical risk index score - NECROSIS - for identifying NSTIs in emergency general surgery (EGS) patients being evaluated for severe skin and soft tissue infections. METHODS: We performed a prospective study across 16 sites in the US of adult EGS patients with suspected NSTIs over a 30-month period. Variables analyzed included demographics, admission vitals and labs, physical exam, radiographic, and operative findings. The main outcome measure was the presence of NSTI diagnosed clinically at the time of surgery. Multivariate analysis was performed to identify independent predictors for the presence of NSTI using the Hosmer-Lemeshow test and the Akaike information criteria. RESULTS: Of 362 patients, 297 (82%) were diagnosed with a NSTI. Overall mortality was 12.3%. Multivariate analysis identified 3 independent predictors for NSTI: systolic blood pressure ≤ 120 mmHg, violaceous skin, and WBC ≥15 (x103/uL). Multivariate modelling demonstrated Hosmer-Lemeshow goodness of fit (p = 0.9) with a c-statistic for the prediction curve of 0.75. Test characteristics of the NECROSIS score were similar between the derivation and validation cohorts. CONCLUSION: NECROSIS is a simple and potentially useful clinical index score for identifying at-risk EGS patients with NSTIs. Future validation studies are warranted. LEVEL OF EVIDENCE: Diagnostic Tests or Criteria, Level III.

Cost Savings of Whole Blood Versus Component Therapy at a Community Level 1 Trauma Center.

BACKGROUND: Blood product component-only resuscitation (CORe) has been the standard of practice in both military and civilian trauma care with a 1:1:1 ratio used in attempt to recreate whole blood (WB) until recent data demonstrated WB to confer a survival advantage, leading to the emergence of WB as the contemporary resuscitation strategy of choice. Little is known about the cost and waste reduction associated with WB vs CORe. METHODS: This study is a retrospective single-center review of adult trauma patients admitted to a community trauma center who received WB or CORe as part of their massive transfusion protocol (MTP) resuscitation from 2017 to 2021. The WB group received a minimum of one unit WB while CORe received no WB. Univariate and multivariate analyses were completed. Statistical analysis was conducted using a 95% confidence level. Non-normally distributed, continuous data were analyzed using the Wilcoxon rank sum test. RESULTS: 576 patients were included (201 in WB and 375 in CORe). Whole blood conveyed a survival benefit vs CORe (OR 1.49 P < .05, 1.02-2.17). Whole blood use resulted in an overall reduction in products prepared (25.8%), volumes transfused (16.5%), product waste (38.7%), and MTP activation (56.3%). Cost savings were $849 923 annually and $3 399 693 over the study period. DISCUSSION: Despite increased patient volumes over the study period (43.7%), the utilization of WB as compared to CORe resulted in an overall $3.39 million cost savings while improving mortality. As such, we propose WB should be utilized in all resuscitation strategies for the exsanguinating trauma patient.

High-grade liver injuries with contrast extravasation managed initially with interventional radiology versus observation: A secondary analysis of a WTA multicenter study.

BACKGROUND: High-grade liver injuries with extravasation (HGLI â€‹+ â€‹Extrav) are associated with morbidity/mortality. For low-grade injuries, an observation (OBS) first-strategy is beneficial over initial angiography (IR), however, it is unclear if OBS is safe for HGLI â€‹+ â€‹Extrav. Therefore, we evaluated the management of HGLI â€‹+ â€‹Extrav patients, hypothesizing IR patients will have decreased rates of operation and mortality. METHODS: HGLI â€‹+ â€‹Extrav patients managed with initial OBS or IR were included. The primary outcome was need for operation. Secondary outcomes included liver-related complications (LRCs) and mortality. RESULTS: From 59 patients, 23 (39.0%) were managed with OBS and 36 (61.0%) with IR. 75% of IR patients underwent angioembolization, whereas 13% of OBS patients underwent any IR, all undergoing angioembolization. IR patients had an increased rate of operation (13.9% vs. 0%, p â€‹= â€‹0.049), but no difference in LRCs (44.4% vs. 43.5%) or mortality (5.6% vs. 8.7%) versus OBS patients (both p â€‹> â€‹0.05). CONCLUSION: Over 60% of patients were managed with IR initially. IR patients had an increased rate of operation yet similar rates of LRCs and mortality, suggesting initial OBS reasonable in appropriately selected HGLI â€‹+ â€‹Extrav patients.

Rib Fractures With Concomitant Spinal Fractures May Benefit From Surgical Stabilization.

Surgical stabilization of rib fractures has demonstrated benefits in patients with complex thoracic injuries. Limited information exists regarding patients with thoracic injuries and concomitant spinal injuries. We hypothesized that patients who suffer both thoracic cage and spinal fractures and undergo surgical fixation (FIX) will have improved outcomes compared to non-fixation (NFIX) patients. In our retrospective review, adult patients with rib injuries from 2015 to 2019 were pooled from the National Trauma Data Bank. Mortality with FIX rib fractures with spinal fractures decreased by 6.1% vs the NFIX group. Mortality of FIX of rib fractures without spinal fractures decreased by 2.2% vs the NFIX group. Patients with rib fractures with concomitant spinal fracture (RFWSF) are more likely to receive rib FIX than those with rib fractures without spinal fractures. Rib FIX in patients with RFWSF vs those with RFWO facilitates less ventilators days and shorter ICU and hospital length of stay (LOS) as well as decreases mortality.

Whole Blood Trauma Resuscitation in Community Trauma Centers Confers Survival Benefit Over Component Therapy.

Whole blood (WB) for trauma resuscitation in civilian populations has become more common. The utilization of WB in community trauma centers has not been reported. Previous studies have centered around large academic medical centers. We hypothesized that WB-based resuscitation compared to component-only resuscitation (CORe) would demonstrate a survival benefit and that WB resuscitation is safe, feasible, and benefits trauma patients regardless of setting. Our results indicate that receiving whole blood during resuscitation conferred a clear survival benefit to discharge, and this benefit was independent of ISS, age, gender, and initial SBP. We conclude WB should be incorporated into all resuscitation protocols for exsanguinating trauma patients and preferred over component therapy in all centers treating trauma patients.

Significant Hypophosphatemia Is Predictive of Brain Death in Severe Traumatic Brain Injury.

Traumatic brain injury (TBI) is one of the most common causes of morbidity and mortality worldwide. Severe TBI carries the greatest risk of brain death progression. There are currently no laboratory markers that predict patient's outcome. We hypothesize that the degree of hypophosphatemia (HP) in TBI is an indicator for progression to brain death. A total of 336 patients, ages 15-89, with a GCS of 8 or less at admission were identified and retrospectively analyzed. Demographics, laboratory studies, and brain death (BD) were collected. Univariate analysis demonstrated HP was correlated with BD (P < .0002). Multivariate analysis showed that phosphate was the only measured electrolyte correlated to BD with a P value < .0001. Mechanism of hypophosphatemia may be related to BD progression and provide future areas for study.

Reconstruction After Grizzly Bear Attack in Wyoming.

Bear attacks are rare, although global incidents have been increasing. Injury patterns of bear attacks against humans consistently include injuries to the face, head, neck, chest, and upper extremities. Here, we have a brief report of a 59-year-old male hunter who was attacked by a grizzly bear in Wyoming. He sustained multiple lacerations to his face which included an avulsion of his nose and upper lip, as well as extensive associated facial fractures. Additional injuries included soft tissue and bony injuries to the upper extremities. He underwent 53 operations during his first hospitalization, primarily of facial reconstruction, which required nose and upper lip replant to his arm. His course was complicated by pressure ulcers, bacteria, acute kidney injury, and a urinary tract infection. After successful coordinated multidisciplinary care and a prolonged hospitalization, he was ultimately discharged to his home.

An observation-first strategy for liver injuries with "blush" on computed tomography is safe and effective.

INTRODUCTION: The management of liver injuries in hemodynamically stable patients is variable and includes primary treatment strategies of observation (OBS), angiography (interventional radiology [IR]) with angioembolization (AE), or operative intervention (OR). We aimed to evaluate the management of patients with liver injuries with active extravasation on computed tomography (CT) imaging, hypothesizing that AE will have more complications without improving outcomes compared with OBS. METHODS: This is a prospective, multicenter, observational study. Patients who underwent CT within 2 hours after arrival with extravasation (e.g., blush) on imaging were included. Exclusion criteria included cirrhosis, nontraumatic hemorrhage, transfers from outside facilities, and pregnancy. No hemodynamic exclusion criteria were used. The primary outcome was liver-specific complications. Secondary outcomes include length of stay and mortality. Angioembolization patients were compared with patients treated without AE. Propensity score matching was used to match based on penetrating mechanism, liver injury severity, arrival vital signs, and early transfusion. RESULTS: Twenty-three centers enrolled 192 patients. Forty percent of patients (n = 77) were initially OBS. Eleven OBS patients (14%) failed nonoperative management and went to IR or OR. Sixty-one patients (32%) were managed with IR, and 42 (69%) of these had AE as an initial intervention. Fifty-four patients (28%) went to OR+/- IR. After propensity score matching (n = 34 per group), there was no difference in baseline characteristics between AE and OBS. The AE group experienced more complications with a higher rate of IR-placed drains for abscess or biloma (22% vs. 0%, p = 0.01) and an increased overall length of stay ( p = 0.01). No difference was noted in transfusions or mortality. CONCLUSION: Observation is highly effective with few requiring additional interventions. Angioembolization was associated with higher rate of secondary drain placement for abscesses or biloma. Given this, a trial of OBS and avoidance of empiric AE may be warranted in hemodynamically stable, liver-injured patient with extravasation on CT. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level II.

Multi-modal Pain Control Protocol Decreases Narcotic Consumption in an Inpatient Trauma Population.

INTRODUCTION: Opioid use after surgery or trauma has been implicated as a contributing factor to opioid dependence. The Acute Care Surgery (ACS) service at our community-based trauma center instituted an opioid-minimizing, multi-modal pain control (MMPC) protocol. The classes of pain medication included a non-opioid analgesic, a non-steroidal anti-inflammatory drug, a gabapentinoid, a skeletal muscle relaxant, and a topical anesthetic. We hypothesize that the MMPC will result in lower opioid consumption compared with the prior STP as evidenced by lower morphine milligram equivalents (MME) per day. METHODS: All adult patients (≥18 years) admitted to the ACS service from Jan 2014 to Dec 2015 and Jan 2018 to Dec 2019 were screened for inclusion. The standard pain control group (STP) and MMPC groups were defined by the year of admission. The primary outcome is opioid use per day, calculated in MME received. Secondary outcomes of the study include daily pain scores, incidence of opioid-related complications, death, ventilator days, intensive care unit length of stay, and hospital length of stay (HLOS) days. RESULTS: Multi-modal pain control protocol group was older and less injured than STP group. Daily opioid utilization was significantly less in the MMPC group (22.5 MMEs/d vs 60MMEs/d in the STP group, P < .0001). Additionally, daily pain scores were not different between groups. Secondary outcomes did not vary between the two groups. CONCLUSION: This study shows that implementation of a MMPC protocol resulted in lower opioid consumption in injured patients. Pain was equivalently controlled during the MMPC protocol period as demonstrated by similar pain scores.

Age-Related Injuries From Escalators.

INTRODUCTION: Escalators and moving stairways are omnipresent in modern life. No study to date has examined nationwide incidence and outcomes associated with injuries directly related to escalator use. The aim of this study was to describe the injury patterns, incidence, and disposition as it pertains to youth compared to adults. METHODS: Descriptive and comparative analyses were performed using National Electronic Injury Surveillance System data. The frequencies of categorical variables were calculated across the two age groups. Chi-squared test was performed on all categorical variables. Significance was defined as two-tailed P < 0.05. Logistic regression was used on variables that were determined to be significant from the frequency tables, with additional variable selection being used to arrive on a final model for each outcome. RESULTS: From 2009 to 2019, there were 810 youth and 3669 adults injured in escalator-associated emergency department visits. Incidence in the youth population decreased over time. Disposition was similar between groups. Injury types were similar among groups. White female adults were more likely to sustain injuries related to escalator use. Adult patients were also significantly more likely to sustain head/neck/facial trauma. Last, adult patients were found to be more likely to suffer a fatal event in comparison to the youth population. DISCUSSION: Differences in the injury patterns between youth and adult patients related to the use of escalators illustrate a need for improved injury prevention. Improved education and safety guidelines, particularly in individuals in ages 18 and up, would likely lessen the discrepancies between age groups identified in this study.

Safety and Outcome of Intracranial Pressure Monitor Placement Performed by Trauma Critical Care Surgeons.

INTRODUCTION: The Brain Trauma Foundation advises intracranial pressure monitor placement (ICPM) following traumatic brain injury (TBI) with a Glasgow Coma Scale (GCS) score ≤8 and an abnormal head computed tomographic scan (CT) finding. Prior studies demonstrated that ICPMs could be placed by non-neurosurgeons. We hypothesized that ICPM placement by trauma critical care surgeons (TCCS) would increase appropriate utilization (AU), decrease time to placement (TTP), and have equivalent complications to those placed by neurosurgeons. METHODS: We retrospectively reviewed medical records of adult trauma patients admitted with a TBI in a historical control group (HCG) and practice change group (PCG). Demographics, Injury Severity Score (ISS), outcomes, ICPM placement by provider type, and time to placement were identified. Complications and appropriate utilization were recorded. RESULTS: 70 patients in the HCG and 84 patients in the PCG met criteria for inclusion. Demographics, arrival GCS, ICU GCS, ISS, and admission APACHE II scores were not statistically significant. AU was 7/70 for HCG vs 19/84 in the PCG (P = .04036). Median TTP was 6.5 hours for HCG vs 5.25 for PCG (P = .9308). Interquartile range showed the data clustered around an earlier placement time, 2.3-14.0 hours, in the PCG. Complications between the 2 groups were not statistically significant, 0/7 for HCG vs 5/19 for PCG (P = .2782). DISCUSSION: This study confirms that ICPMs can be safely placed by TCCS. Our results demonstrate that placement of ICPMs by TCCS improves AU and possibly improves TTP.

Obesity is Not Associated With Need for Skin Grafting After Hidradenitis Excision.

INTRODUCTION: Hidradenitis suppurativa (HS) is a chronic, debilitating disease associated with inflammation, recurrent abscesses, and fistulae of skin containing apocrine sweat glands. We hypothesize that the need for skin grafting after vacuum-assisted closure was decreased with increasing body mass index (BMI). METHODS: Seventy-one consecutive patients with excisions for HS were retrospectively evaluated for demographic data, number of excisions, the total area of excised skin, need for skin grafting, and BMI. Patients were stratified for BMI and underwent logistic regression to compare all other variables. RESULTS: Average for BMI was 30.8 ± 7.72, age was 36.89 ±13.52, area excised was 743 cm2 ± 774 cm2, mean operating room trips were 2.62 ± 1.59, and skin grafting was 0.52 ± 0.55. Patients were 60% male. Forty out of 71 patients were obese. There was no correlation between age, BMI, sex, thenumber of excisions, amount of skin excised, or need for a skin graft. There was a statistically significant relationship between the amount of skin excised and the need for skin grafting (P = .006). CONCLUSIONS: The amount of skin affected by HS appears to be independent of patient BMI. The need for skin grafting is solely dependent upon the amount of tissue excised. APPLICABILITY OF RESEARCH TO PRACTICE: This knowledge will help preoperative planning for all patients with HS, regardless of BMI.

Peritoneal cavity lavage reduces the presence of mitochondrial damage associated molecular patterns in open abdomen patients.

BACKGROUND: Mitochondrial damage-associated molecular patterns (mtDAMPs), such as mitochondrial DNA and N-formylated peptides, are endogenous molecules released from tissue after traumatic injury. mtDAMPs are potent activators of the innate immune system. They have similarities with bacteria, which allow mtDAMPs to interact with the same pattern recognition receptors and mediate the development of systemic inflammatory response syndrome (SIRS). Current recommendations for management of an open abdomen include returning to the operating room every 48 hours for peritoneal cavity lavage until definitive procedure. These patients are often critically ill and develop SIRS. We hypothesized that mitochondrial DAMPs are present in the peritoneal cavity fluid in this setting, and that they accumulate in the interval between washouts. METHODS: We conducted a prospective pilot study of critically ill adult patients undergoing open abdomen management in the surgical and trauma intensive care units. Peritoneal fluid was collected daily from 10 open abdomen patients. Specimens were analyzed via quantitative polymerase chain reaction (qPCR) for mitochondrial DNA (mtDNA), via enzyme immunoassay for DNAse activity and via Western blot analysis for the ND6 subunit of the NADH: ubiquinone oxidoreductase, an N-formylated peptide. RESULTS: We observed a reduction in the expression of ND6 the day after lavage of the peritoneal cavity, that was statistically different from the days with no lavage (% change in ND6 expression, postoperative from washout: -50 ± 11 vs. no washout day, 42 ± 9; p < 0.05). Contrary to expectation, the mtDNA levels remained relatively constant from sample to sample. We then hypothesized that DNAse present in the effluent may be degrading mtDNA. CONCLUSION: These results indicate that the peritoneal cavity irrigation reduces the presence of mitochondrial DAMPs in the open abdomen. It is possible that increased frequency of peritoneal cavity lavage may lead to decreased systemic absorption of mtDAMPs, thereby reducing the risk of SIRS. LEVEL OF EVIDENCE: Prospective study, Case Series, Level V.

Thoracic Trauma in the Oldest of the Old: An Analysis of the Nationwide Inpatient Sample.

Thoracic trauma (TT) has the second highest mortality rate in the geriatric population. These injuries cause significant morbidity in elderly patients. Little has been done to describe the demographics and mortality of specific injuries in these patients. ICD-9 codes corresponding with thoracic trauma for patients aged >80 years were extracted from the Nationwide Inpatient Sample database from 2000 to 2010. Characteristics including gender, race, Charlson Comorbidity Index (CCI), length of stay (LOS), and in-hospital mortality (IHM) were analyzed. For females and males, mean CCI was 4.84 and 4.93, respectively (P < 0.0001), and IHM was 5.49 and 2.44 per cent, respectively (P < 0.0001). For white and non-white patients, mean CCI was 4.88 and 4.84, respectively (P < 0.05), and IHM was 3.5 and 3.19 per cent, respectively. This difference was not statistically significant (P = 0.149). Logistic regression revealed correlation coefficient between CCI and mortality was 0.314 (P < 0.0001). Fitting a regression of CCI on LOS adjusting for gender and race, the adjusted effect was 0.146 (P < 0.0001). LOS was significantly less for patients surviving hospitalization. Males had higher CCI and mortality than females. Although whites had a higher CCI than non-whites, there was no difference in IHM between these two groups.
