Thoracotomy Resuscitation of a Patient Who Sustained Blunt Force Trauma with a pH of 6.7 on Admission and Ultra Massive Transfusion of 42 Units of Blood.

Extreme acidosis is a life-threatening physiological state that thwarts resuscitative actions and most frequently ends in mortality. This report describes a case of a successful resuscitation in a patient who presented without vital signs, agonal respirations, dilated, unresponsive pupils, and an initial pH of 6.7. The patient is a 37-year-old man who was ejected from his package delivery vehicle after it was struck by a loaded dump truck. Resuscitative thoracotomy and other ATLS measures were performed to restore spontaneous circulation at 13 minutes after arrival. He underwent subsequent emergent operative interventions for severe chest, lower extremity, and intra-abdominal injuries. He was transfused 15, 27, and 42 total units of packed red blood cells (U-pRBCs) at resuscitation hours 2, 4, and 24. This case reinforces that resuscitative measures should be undertaken on a case-specific basis despite generalized guidelines suggesting futility at pH below 7.0 and at 23 units pRBCs balanced transfusion.

Incidence and Risk Factors for ICU-Associated Delirium in the Alert Geriatric Trauma Population.

BACKGROUND: This study analyzed the overall incidence of delirium, comorbid conditions, injury patterns, and pharmacological risk factors for the development of delirium in an alert, geriatric trauma population. METHODS: IRB-approved, prospective, consecutive cohort series at two Southeastern Level 1 trauma centers from June 11 to August 15, 2023. Delirium was assessed using the Confusion Assessment Method (CAM) score. Comorbidities and medications were detailed from electronic medical records. Inclusion criteria: age ≥55, GCS ≥14, and ICU admission for trauma. Patients on a ventilator were excluded. Data was analyzed using SPSS version 28 (Armonk, NY: IBM Corp). RESULTS: In total, 196 patients met inclusion criteria. Incidences of delirium for Hospital 1 (n = 103) and Hospital 2 (n = 93) were 15.5% and 12.9%, respectively, with an overall incidence of 14.3% and with no statistical differences between hospitals (P = .599). CAD, CKD, dementia, stroke history, and depression were statistically significant risk factors for developing delirium during ICU admission. Inpatient SSRI/SNRIs, epinephrine/norepinephrine, and lorazepam were significant risk factors. Injury patterns, operative intervention, and use of lidocaine infusions and gabapentin were not statistically significant in delirium development. Using binary linear regression (BLR) analysis, independent risk factors for delirium were dementia, any stage CKD, home SSRI/SRNI prescription, any spine injury and cerebrovascular disease, or injury. DISCUSSION: Comorbidities of CAD, CHF, CKD, and depression, and these medications: home lorazepam and ICU epinephrine/norepinephrine statistically are more common in patients developing delirium. Dementia, CKD, home SSRI/SRNI and stroke/cerebrovascular disease/injury, and spine injuries are independent predictors by BLR.

Delayed vs Early Admission to Intensive Care: A Retrospective Review of Outcomes and Clinical Indicators of Deterioration Following Trauma.

Unplanned admission to an intensive care unit (ICU) is a trauma quality improvement indicator associated with increased morbidity, mortality, and hospital resource usage. We identified demographics, injuries, and other clinical factors between early ICU admission, <72 hrs after admission (EAd), and delayed admission, >72 hrs (DelAd) from a medical/surgical floor. 146 trauma patients admitted to ICU at a level 1 trauma center from January 2020 to March 2023 met inclusion criteria and were divided into EAd and DelAd. No statistical differences in injury mechanism or severity were observed. Delayed admission demonstrated higher mortality (P = .001), more frequent decline in GCS (P = .045), and initiation of anticoagulation (P = .002). Abnormal EKG, orthopedic surgery during admission, and home anticoagulant and antidepressant use were statistically significant in identifying patients requiring early ICU admission.

Surgical Resident Education and Performance in Extended Focused Abdominal Sonography for Trauma.

Extended focused assessment with sonography for trauma (eFAST) is a rapid triage tool aiding the detection of life-threatening injuries. In academic settings, residents perform most eFAST; however, the ACGME has no recommendations for eFAST training standards. We surveyed general surgery programs (GSPs) regarding eFAST training and established a baseline for sensitivity, specificity, and positive and negative predictive values for resident-performed eFAST. US GSP eFAST surveys were conducted by email and phone. We prospectively collected patient variables and evaluated resident performance from May to September 2022 and 2023 at an academic level I trauma center. A total of 60/339 general surgery residency programs (GSRPs) responded: Ten use Advanced Trauma Life Support (ATLS) only, n = 7 group training, n = 8 on-the-job only, and n = 33 several methods. Resident-performed eFAST had accuracy = 85.6%, sensitivity = 35.6%, specificity = 97.2%, PPV = 75%, and NPV = 87%. General surgery residency program training in eFAST is non-standardized. Sensitivity was considerably lower than the literature suggests. Positive resident-performed eFAST is generally accurate. We recommend a standardized approach to resident training in eFAST.

Coronary Artery Calcification and Risk of Cardiac Complication in Geriatric Trauma Population.

BACKGROUND: Better means of identifying patients with increased cardiac complication (CC) risk is needed. Coronary artery calcification (CAC) is reported on routine chest CT scans. We assessed the correlation of CAC and CCs in the geriatric trauma population. STUDY DESIGN: A prospective, observational study of patients 55 years and older who had chest CT scan from May to September 2022 at a level 1 trauma center. Radiologists scored CAC as none, mild, moderate, or severe. None-to-mild CAC (NM-CAC) and moderate-to-severe CAC (MS-CAC) were grouped and in-hospital CCs assessed (arrhythmia, ST elevation myocardial infarction [STEMI], non-STEMI, congestive heart failure, pulmonary edema, cardiac arrest, cardiogenic shock, and cardiac mortality). Univariate and bivariate analyses were performed. RESULTS: Five hundred sixty-nine patients had a chest CT, of them 12 were excluded due to missing CAC severity. Of 557 patients, 442 (79.3%) had none-to-mild CAC and 115 (20.7%) has MS-CAC; the MS-CAC group was older (73.3 vs 67.4 years) with fewer male patients (48.7% vs 54.5%), had higher cardiac-related comorbidities, and had higher abbreviated injury scale chest injury scores. The MS-CAC group had an increased rate of CC (odds ratio [OR] 1.81, p = 0.016). Cardiac complications statistically more common in MS-CAC were congestive heart failure (OR 3.41, p = 0.003); cardiogenic shock (OR 3.3, p = 0.006); non-STEMI I or II (OR 2.8, p = 0.017); STEMI (OR 5.9, p = 0.029); and cardiac-caused mortality (OR 5.27, p = 0.036). No statistical significance between pulmonary edema (p = 0.6), new-onset arrhythmia (p = 0.74), or cardiac arrest (p = 0.193). CONCLUSIONS: CAC as reported on chest CT scans demonstrates a significant correlation with CC and should warrant additional cardiac monitoring.

Surgical Repair of Idiopathic Mid-Forearm Radial Artery Aneurysm Using a Reversed Greater Saphenous Vein Interposition Graft.

Idiopathic, non-traumatic, radial artery aneurysms are rare in medical literature. This report presents the case of a 56-year-old man who was incidentally found to have a 1.01 cm × 1.31 cm left radial artery aneurysm during a carpal tunnel workup. The patient had no other aneurysms, nor any known predisposing diseases that could explain his condition. We proceeded with surgical intervention to prevent future complications. We describe the use of a greater saphenous vein interposition graft for the repair of an idiopathic mid-forearm radial artery aneurysm. The patient had an uncomplicated recovery course following repair.

"Early Post-operative Mechanical Small Bowel Obstruction Induced by Unidirectional Barbed Suture".

Unidirectional barbed suture is widely used in minimally invasive procedures as a secure alternative to traditional knot tying. In this report, a 44-year-old female with endometriosis and complex gynecological history presented to our emergency department 2 weeks after undergoing minimally invasive gynecological surgery. She had persistent, progressive signs and symptoms typical of intermittent partial small bowel obstruction. On her third admission within 7 days for this pattern, laparoscopic abdominal exploration was performed. She was noted to have small bowel obstruction secondary to ingrowth of the tail of a unidirectional barbed suture kinking the terminal ileum during this procedure. We discuss small bowel obstruction due to unidirectional barbed suture and make recommendations on how to avoid this complication.

The Effect of BMI on eFAST Accuracy in Trauma by Residents in the Emergency Room.

Blunt trauma patients are often evaluated with extended focused assessment with sonography for trauma (eFAST). eFAST is a noninvasive, rapid, ultrasound-guided assessment for hemoperitoneum, pericardial effusion, and hemopneumothorax. Specificity and sensitivity are as high as 95% and 74%, respectively. Research suggests obesity confers increased morbidity and mortality and is an independent risk factor for trauma death. A previous study demonstrated that a BMI change from 36 to 40 changed the odds ratio for inaccurate eFAST from 1.85 to 3.12. Our current prospective data collection is 202 consecutive blunt trauma patients from 5/13/22 to 8/18/22 receiving an eFAST and a CT/OR for comparison. Odds ratio of inaccurate eFAST increased by 5.65% for each increase of 1 kg/m3 of BMI (95% Cl 0.1%-10.8%). This research also investigated surgical resident eFAST accuracy to improve patient outcomes through the implementation of individualized training in normal and obese models.

Effect of Timing of Readmission to the ICU on Mortality in Trauma Patients Requiring Critical Care.

ICU readmission is associated with increased mortality. The primary goal of our investigation was to determine the impact of early ICU readmission on mortality and to identify clinical factors which contribute to early ICU readmission in the trauma population. We retrospectively reviewed 175 patients admitted to ICU in a single, academic Level I Trauma Center from January 2019 to December 2021. Early readmission was defined as readmission within 72 hours of discharge and late readmission as after 72 hours. Early readmission mortality rate was 2.8 times higher than late readmission. Statistically significant variables in early readmission were more operations >2 hours, shorter initial length of stay in ICU, lower hematocrit and paCO2 on ICU discharge, and presence of a psychiatric diagnosis. Additional prospective research is needed to guide the development of practice guidelines that reduce frequency, morbidity, and mortality associated with ICU readmission in the trauma population.

Improving Opioid Prescribing Post-Discharge for Trauma Patients With Rib Fractures: Factors in Prevention of Prolonged Use and Dependency.

BACKGROUND: Rib fracture (RF) pain management provides analgesia while reducing opioids. We postulated: (1) Prescriber factors affect opiate duration, and (2) lidocaine infusion curtails dependency. MATERIALS AND METHODS: Retrospective study of RF patients undergoing multimodal analgesia at ACS-verified Level 1 Trauma Center April 2018-February 2020. Exclusions: age<18 y/o, GCS < 14, hospital length of stay (LOS) <3 d, <3 RF, ventilator support, injury-related mortality, disclosed/discoverable, acute/chronic opiate Rx within 90 days preadmission, substance abuse, patient inaccessible via Controlled Substance Monitoring Database (CSMD), and/or not using opioids in-/post-hospitalization. CSMD queried regarding opioid prescriptions filled by cohort. Cohort variable analysis performed on SPSS Version 27sf (Armonk, NY: IBM Corp). RESULTS: 153 patients included - 113 (74%) stopped opiates by 30 days post-discharge (NORx30), 40 (26%) continued beyond 30 days (Rx+). No significant differences in age, gender, ISS, number of RF, bilaterality, flail chest, and discharge disposition. Significant differences included hospital LOS (7.62 NORx30 vs. 10.22 Rx+, p = .02), number of prescribers (1.73 NORx30 vs. 2.98 Rx+, p < .01), average MME/day during initial 30 days post-discharge (36.7 ± 17 NORx30 vs. 45.4 ± 30.2 Rx+, p = .03), and number of pills (49 ± 38 NORx30 vs. 120 ± 85 Rx+, p < .01). Patients who received lidocaine infusion (LIDO+) had lower MME/day prescribed (32.24 ± 19.9, p = .03), were younger (61.2 vs. 65.6, p < .01), had more RFs (7.1 vs. 6.05, p = .03), and shorter LOS (7.71 vs 10.2, p = .01). DISCUSSION: Prescriber attention to MME/day and number of pills dispensed affects opioid dependency. We recommend 35-40 MME/day with 50 pill/month limit prescribed by a single provider monitoring patient and CSMD. Early LI offers post-discharge opioid cessation advantage.

Incidental Findings in the Trauma Population: Interdisciplinary Approach and Electronic Medical Record Reminder Association with Pre-Discharge Reporting and Medicolegal Risk.

BACKGROUND: Incidental findings (IFs) are reported in 20% or more of trauma CT scans. In addition to the importance of patient disclosure, there is considerable legal pressure to avoid missed diagnoses. We reported previously that 63.5% of IFs were disclosed before discharge and with 20% were nondisclosed. We initiated a multidisciplinary systemic plan to effect predischarge disclosure by synoptic CT reports with American College of Radiology recommended follow-up, electronic medical records discharge prompts, and provider education. STUDY DESIGN: Prospective observational series patients from November 2019 to February 2020 were included. Statistical analysis was performed with SPSS, version 21 (IBM Corp). RESULTS: Eight hundred and seventy-seven patients underwent 1 or more CT scans for the evaluation of trauma (507 were male and 370 were female). Mean age of the patients was 57 years (range 14 to 99 years) and 96% had blunt injury. In 315 patients, there were 523 IFs (1.7 per patient); the most common were lung (17.5%), kidney (13%), and liver (11%). Radiology report compliance rate was 84% (210 of 249 patients). There were 66 studies from outside facilities. Sixteen IFs were suspicious for malignancy. A total of 151 patients needed no follow-up and 148 patients needed future follow-up evaluation. Predischarge IF disclosure compliance rate was 90.1% (286 patients); 25 were post discharge. Four patients remained undisclosed. Compared with our previous report, clearer reporting and electronic medical records prompts increased predischarge disclosure from 63.5% to 90.1% (p < 0.01, chi-square test) and decreased days to notification from 29.5 (range 0 to 277) to 5.2 (range 0 to 59) (p < 0.01, Mann-Whitney U test). CONCLUSIONS: Timely, complete disclosure of IFs improves patient outcomes and reduces medicolegal risk. Collaboration among trauma, radiology, and information technology promotes improved disclosure in trauma populations.

Cervical spine collar clearance in the obtunded adult blunt trauma patient: a systematic review and practice management guideline from the Eastern Association for the Surgery of Trauma.

BACKGROUND: With the use of the framework advocated by the Grading of Recommendations Assessment, Development and Evaluation (GRADE) Working Group, our aims were to perform a systematic review and to develop evidence-based recommendations that may be used to answer the following PICO [Population, Intervention, Comparator, Outcomes] question:In the obtunded adult blunt trauma patient, should cervical collar removal be performed after a negative high-quality cervical spine (C-spine) computed tomography (CT) result alone or after a negative high-quality C-spine CT result combined with adjunct imaging, to reduce peri-clearance events, such as new neurologic change, unstable C-spine injury, stable C-spine injury, need for post-clearance imaging, false-negative CT imaging result on re-review, pressure ulcers, and time to cervical collar clearance? METHODS: Our protocol was registered with the PROSPERO international prospective register of systematic reviews on August 23, 2013 (REGISTRATION NUMBER: CRD42013005461). Eligibility criteria consisted of adult blunt trauma patients 16 years or older, who underwent C-spine CT with axial thickness of less than 3 mm and who were obtunded using any definition.Quantitative synthesis via meta-analysis was not possible because of pre-post, partial-cohort, quasi-experimental study design limitations and the consequential incomplete diagnostic accuracy data. RESULTS: Of five articles with a total follow-up of 1,017 included subjects, none reported new neurologic changes (paraplegia or quadriplegia) after cervical collar removal. There is a worst-case 9% (161 of 1,718 subjects in 11 studies) cumulative literature incidence of stable injuries and a 91% negative predictive value of no injury, after coupling a negative high-quality C-spine CT result with 1.5-T magnetic resonance imaging, upright x-rays, flexion-extension CT, and/or clinical follow-up. Similarly, there is a best-case 0% (0 of 1,718 subjects in 11 studies) cumulative literature incidence of unstable injuries after negative initial imaging result with a high-quality C-spine CT. CONCLUSION: In obtunded adult blunt trauma patients, we conditionally recommend cervical collar removal after a negative high-quality C-spine CT scan result alone. LEVEL OF EVIDENCE: Systematic review, level III.

Unsafe at any age: a retrospective review of all-terrain vehicle injuries in two level I trauma centers from 1995 to 2003.

BACKGROUND: All-terrain vehicles (ATVs) are popular recreational and utility vehicles. In 1984, Cogbill published an article regarding three-wheelers. These are no longer manufactured, but the injury and death rate with four-wheeled ATVs is high and disproportionately affects young riders. METHODS: We conducted a retrospective review at two Level I trauma centers from January 1994 to April 2003. Statistical analysis was performed using the SAS V8.2 program. Values of p < 0.05 were significant. RESULTS: Two hundred eight patients were identified. There were no differences identified in demographics, mechanism, types of injury, Injury Severity Score (ISS), or Glasgow Coma Scale (GCS) score. Seventy-five percent were male and 84% were white. The mean age was 23 +/- 13 years. The average ISS was 12.3 +/- 9 and the mean GCS score was 13.1 +/- 3.7. Injury mechanisms were loss of stability (33%), separation of rider from ATV (32%), and ATV versus stationary object (27%). ISS for ages 12 to 15 years was significantly higher than for other ages (14.5 vs. 11.5, p = 0.04, Wilcoxon rank sum test) and included more major head injuries (40.4% vs. 21.8%, p = 0.09, Wilcoxon rank sum test). They experienced fewer spinal fractures (3.9% vs. 15.4%, p = 0.03) and pelvic injuries (0% vs. 9%, p = 0.02, Wilcoxon rank sum test). The GCS score in this group was lower (12.3 vs. 13.4, p = 0.03, Wilcoxon rank sum test). CONCLUSION: Adolescent ATV riders have more severe injuries and more head injuries than other age groups. Prevention efforts should target this group.

An analysis of Eastern Association for the Surgery of Trauma practice guidelines for cervical spine evaluation in a series of patients with multiple imaging techniques.

We conducted a retrospective review of 124 consecutive patients who received all of the following studies between October 1998 and December 1999: three-view plain films (3VPF), full CT survey (CTS), and MRI of the cervical spine. We compared the EAST guidelines for 1) patients with persistent neck pain, 2) those with neurologic deficits (NDs), and 3) those who were obtunded in our study group to determine whether EAST recommendations would risk a significant missed injury rate. The average age was 28 years (range 5 months-78 years). There were 94 males and 30 females. The mean Injury Severity Score (ISS) was 16.8 and the mean Glasgow Coma Score (GCS) 10.87. The most common mechanism of injury was motor vehicle crash (58%) followed by falling (15%), auto versus pedestrian (9%), all-terrain vehicle accident (4%), assault (3%) and other (11%). For comparisons we identified a group of 33 patients with normal mental status and normal 3VPF. Twenty patients had MRI for persistent neck pain. Eleven of 20 had normal MRI. The nine abnormal MRIs showed: six ligamentous injuries, two cord compressions, and one nonligamentous soft-tissue injury. Thirteen of the 33 patients had MRI for ND. Six had normal MRI and all these NDs resolved. The remaining seven MRIs showed: two disc herniations, two cord contusions, one cord edema, one lumbar fracture, and one brachial plexus avulsion. We also examined a group of 51 obtunded patients with normal 3VPF. Thirty-six of 51 had normal CTS and MRI. Ten patients had an abnormal MRI, two an abnormal CTS, and three abnormal MRI and CTS. No obtunded patient with an adequate 3VPF had an injury identified below C2 using CTS and MRI. In the 10 patients with abnormal MRI the mean age was 28.4 years, the mean GCS 6.6 (P = 0.0025), and the mean ISS 24.3 (P = 0.03) (Wilcoxson two-sample test). The injuries identified by MRI were four disc herniations, two ligamentous injuries, two soft-tissue traumas, one meningeal tear, and one cord transection. Thirty per cent of patients with persistent neck pain had potentially unstable injuries not detected by 3VPF or CTS. Fifty-four per cent of patients with ND had abnormal MRI. Twenty-two per cent of obtunded patients with normal 3VPF and CTS had an abnormal MRI. These patients have a significantly lower GCS and a higher ISS. Six per cent of these injuries were potentially unstable. Our data support EAST guidelines for patients with persistent neck pain and ND. The guidelines for obtunded patients appear safe in detecting bony injury but may not be sensitive enough for unstable ligamentous injury and significant disc herniations.
