Changes in Patterns of Trauma Injuries in the Dakotas Region During the COVID-19 Pandemic.

BACKGROUND: The aim of this study is to compare impact of COVID-19 on trauma volume and characteristics on a set of trauma centers with a rural catchment area. The COVID-19 pandemic has affected different parts of the country quite differently, both in case volume and in local responses. State-wide responses have varied considerably, including variations in local mask mandates, school closures, and social distancing measures. METHODS: This was a retrospective trauma registry review of patients who were admitted to three of the tertiary care trauma centers in North and South Dakota between 2014 through 2022. RESULTS: In the analysis of 36,397 patients, we found a significant increase in trauma patient volume during the COVID-19 pandemic, with an increased percentage of patients presenting with a mechanism of injury secondary to abuse or assault. This increase in patient volume continued to rise during 2021 and 2022. CONCLUSIONS: Our study demonstrates how the COVID-19 pandemic impacted trauma center admissions in the rural and frontier Midwest differently from more urban areas, and the importance of including a variety of settings in trauma research.

Moving the needle on time to resuscitation: An EAST prospective multicenter study of vascular access in hypotensive injured patients using trauma video review.

BACKGROUND: Vascular access in hypotensive trauma patients is challenging. Little evidence exists on the time required and success rates of vascular access types. We hypothesized that intraosseous (IO) access would be faster and more successful than peripheral intravenous (PIV) and central venous catheter (CVC) access in hypotensive patients. METHODS: An EAST prospective multicenter trial was performed; 19 centers provided data. Trauma video review was used to evaluate the resuscitations of hypotensive (systolic blood pressure ≤90 mm Hg) trauma patients. Highly granular data from video recordings were abstracted. Data collected included vascular access attempt type, location, success rate, and procedural time. Demographic and injury-specific variables were obtained from the medical record. Success rates, procedural durations, and time to resuscitation were compared among access strategies (IO vs. PIV vs. CVC). RESULTS: There were 1,410 access attempts that occurred in 581 patients with a median age of 40 years (27-59 years) and an Injury Severity Score of 22 [10-34]. Nine hundred thirty-two PIV, 204 IO, and 249 CVC were attempted. Seventy percent of access attempts were successful but were significantly less likely to be successful in females (64% vs. 71%, p = 0.01). Median time to any access was 5.0 minutes (3.2-8.0 minutes). Intraosseous had higher success rates than PIV or CVC (93% vs. 67% vs. 59%, p < 0.001) and remained higher after subsequent failures (second attempt, 85% vs. 59% vs. 69%, p = 0.08; third attempt, 100% vs. 33% vs. 67%, p = 0.002). Duration varied by access type (IO, 36 [23-60] seconds; PIV, 44 [31-61] seconds; CVC 171 [105-298]seconds) and was significantly different between IO versus CVC ( p < 0.001) and PIV versus CVC ( p < 0.001) but not PIV versus IO. Time to resuscitation initiation was shorter in patients whose initial access attempt was IO, 5.8 minutes versus 6.7 minutes ( p = 0.015). This was more pronounced in patients arriving to the hospital with no established access (5.7 minutes vs. 7.5 minutes, p = 0.001). CONCLUSION: Intraosseous is as fast as PIV and more likely to be successful compared with other access strategies in hypotensive trauma patients. Patients whose initial access attempt was IO were resuscitated more expeditiously. Intraosseous access should be considered a first line therapy in hypotensive trauma patients. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level II.

Consistency is Key: Additional Education and Outreach in a Rural Trauma System Reduces Excess Imaging Studies.

BACKGROUND: Repeat imaging for trauma patients is common in rural health care systems after transfer to a tertiary trauma center which subjects patients to increased radiation, excess costs, and delays to definitive care. A previous retrospective review at our regional trauma center found that pre-transfer CT scans were frequently performed with little change in management. To improve this rate, additional emphasis was placed on (1) best imaging practices during Rural Trauma Team Development Courses (RTTDC), (2) management feedback during regional trauma case reviews, and (3) implementation of practice management guidelines for an inter-provider telehealth system. METHODS: Two hundred consecutive adult trauma patients transferred to a regional trauma center were retrospectively evaluated after trauma system improvements were implemented and compared to the previous cohort in the same system as identified by the regional trauma database. RESULTS: 140 (70%) had a pre-transfer CT scan compared to 152 (77.2%) in the prior study (P = .0112). Additionally, 52 (37.1%) of those with pre-transfer CT scans had at least one repeat scan on arrival which decreased from (55.3%) in the prior study (P < .0001). The most common reason for repeat CT scans was incomplete initial imaging. Those with a repeat scan were more likely to have a head injury (51.9% vs 35.8%, P = .0413). DISCUSSION: With regional trauma system maturation and implementation of internal telemedicine guidelines, there was a statistically significant decrease in both pre-transfer as well as repeat CT scans in a rural trauma system. Additional research exploring patient outcomes and cost savings is recommended.

79 is the new 70: Left digit bias in craniotomy.

BACKGROUND: Left digit bias is the psychological phenomenon in which the difference between values is perceived as larger due to the value of the first digit. For example, an 80 year old may be perceived as much older than a 79 year old. We sought to determine if left digit bias is present in craniotomy for elderly patients with traumatic brain injury. METHODS: Patients aged 69, 70, 79, and 80 with traumatic brain injury and an abbreviated injury scale severity of a minimum of 3 were included from the National Trauma Data Bank from the years 2012-2019. 38,908 patients were included. A Chi-squared Test was performed to compare the percentage of patients undergoing craniotomy. RESULTS: 79 year olds had higher craniotomy rates than 80 year olds (7.8% vs 6.4%, P < 0.001). There was no difference in craniotomy rates between 69 and 70 year olds (8.2% vs 7.8%, P < 0.2622). CONCLUSION: This study suggests the presence of left digit bias in the decision to perform a craniotomy in patients aged 79 vs 80 with traumatic brain injury.

Mesenteric Extra-adrenal Paraganglioma - An Unusual Cause of Intermittent Abdominal Pain.

Paragangliomas are non-epithelial tumors of neuroendocrine origin that arise from the paraganglia of the sympathetic and parasympathetic nervous system. These paraganglia cells are derived from the neural crest and can be found anywhere in the body where paraganglia exist. Paragangliomas are rare tumors. It is estimated that the incidence of pheochromocytoma (intra-adrenal paraganglioma) and extra-adranal paraganglioma is 0.8 per 100,000 person years. It is commonly stated that 10 percent of paragangliomas are extra-adrenal. The majority of parasymphathetic paragangliomas reside in the skull base and along the vagus and glossopharyngeal nerves, whereas the majority of sympathetic paragangliomas can be found in the abdomen. Paragangliomas found in the mesentery are exceedingly rare, with 12 reported cases identified in the literature. We present the case of a 61-year-old female who presented to our institution with a suspected superior mesenteric artery aneurysm who was ultimately found to have an extra-adrenal paraganglioma within the small bowel mesentery of the right lower quadrant of the abdomen.

Current Trends in Surgical Procedures Performed in Rural General Surgery Practice.

BACKGROUND: The procedures that rural general surgeons perform may be changing. It is important to recognize the trends and practices of the current rural general surgeon in efforts to better prepare general surgeons who desire to enter a practice in a rural environment. The aim of this review is to detail the recent operative case volumes of 6 rural locations in the upper Midwest where general surgery is practiced. METHODS: The Enterprise Data and Analytics department of Sanford Health compiled all surgical procedures performed within the Sanford Health System between January 1, 2013 and August 31, 2018. Procedures performed by a total of 58 general surgeons in locations of under 50 000 people are included in this review. RESULTS: From January 1, 2013 to August 31, 2018, 38 958 surgical procedures were performed in rural locations. Endoscopic procedures made up 61.6% of a rural general surgeon's practice. Cholecystectomy (6.3%), hernia repair (6.3%), and appendectomy (3.7%) were the principle nonendoscopic procedures performed by rural surgeons, comprising 16.3% of the case volume. Added together, endoscopy, cholecystectomy, hernia repair, and appendectomy made up 77.9% of the rural general surgeon's caseload. Vascular procedures (2.5%), breast procedures (1.8%), obstetrics (0.4%), and urology procedures (0.2%) are also included in this review. CONCLUSIONS: Rural general surgeons are vital to the surgical workforce in the United States. Recognizing a trend that rural general surgeons perform less subspecialty procedures and more endoscopic procedures will provide direction for those interested in pursuing a career in rural general surgery.

A Case Report of Isolated Blunt Traumatic Gallbladder Perforation and Review of the Literature.

INTRODUCTION: Gallbladder trauma is an uncommon occurrence, most commonly found incidentally at the time of laparotomy for associated injuries following abdominal trauma. It is even more rare in blunt abdominal trauma, with one of the rarest forms being an isolated injury to the gallbladder. Awareness for this type of injury should not be forgotten by emergency personal when evaluating someone with a history of recent trauma. CASE DESCRIPTION: A 44-year-old male who works as a construction worker fell from a roof, landing on his right side. Upon evaluation by the emergency department, emergency personnel combined the history, abnormal laboratory values and imaging including ultrasound (U/S) and computed tomography (CT) to assess and diagnose a concern for gallbladder perforation. He was treated with a diagnostic laparoscopy, laparoscopic cholecystectomy, and intraoperative choleangiogram. The patient tolerated the procedure well and discharged home on postoperative day 1. DISCUSSION: Gallbladder trauma can be seen in all population types. As the gallbladder is fairly protected, it is rare to have an isolated injury. A detailed history as described can tip off practitioners to the diagnosis, but is also missed or delayed due to occasionally vague symptoms. Imaging studies can be used adjunctively to assist in diagnosis and may include CT, U/S, color Doppler, or HIDA scans. These can also fail to give a diagnosis leading to a missed injury and further morbidity and mortality. Perforated gallbladders can safely be treated laparoscopically as well as other options depicted. CONCLUSION: Awareness of isolated and rare injuries in trauma, such as those to the gallbladder, enables many types of emergency personnel to recognize and treat patients and consequently prevent the morbidity and mortality of a missed injury.

Transanal stricturoplasty: a minimally-invasive approach to a challenging problem.

Despite the advances in the surgical techniques and technology in colorectal surgery, the development of rectal anastomotic stricture is a common problem. In some case series, the incidence is estimated to be as high as 30%. Some of the known risk factors for developing a stricture include anastomotic leak and ischemia. Treatment options range from frequent dilations using digital rectal examinations and dilators if the stricture is low or endoscopic balloon dilations for higher strictures. Unfortunately, multiple sessions are typically required to achieve adequate results. We present a case report of a benign anastomotic stricture and describe a novel approach, transanal stricturoplasty, for this challenging problem.

Pretransfer CT scans are frequently performed, but rarely helpful in rural trauma systems.

BACKGROUND: Rural trauma patients often undergo workup prior to transfer to a trauma center. Repeat and redundant imaging at the trauma center is common. METHODS: Two hundred consecutive adult trauma patients transferred to a regional trauma center were retrospectively evaluated. RESULTS: 197 patients met criteria. 152 underwent CT scan prior to transfer and CT was the indication for transfer in 88 patients (44.7%). One intervention was performed as a result of CT imaging. 84 patients (55.3%) received repeat CT imaging. There were no statistically significant differences in rates of CT imaging at the outside facility based on injury severity, mechanism of injury, or age. The most common reason for repeat CT scans was incomplete initial imaging. The ability to obtain initial imaging was not a significant factor. CONCLUSIONS: Repeat CT imaging in transferred trauma patients is very common. The majority of reimaging is done for incomplete initial imaging. Rural trauma systems may benefit from improved protocols for more efficient care.

Evaluation of chest tube administration of tissue plasminogen activator to treat retained hemothorax.

BACKGROUND: When retained hemothorax occurs, video-assisted thoracoscopy or thoracotomy is performed, but recently, tissue plasminogen activator (tPA) has been used. This study evaluated intrapleural tPA use for retained traumatic hemothoraces. METHODS: A retrospective review was conducted of trauma patients treated with intrapleural tPA for retained hemothorax. Data included demographics, past medical and surgical histories, injury details, treatment details, and outcomes. RESULTS: Seven patients (median age = 47 years, male = 6, blunt trauma = 6) met study criteria. All patients received a chest tube. Six patients later received computed tomography-guided drains for tPA infusion. Number of tPA treatments per patient varied from 1 to 5. Median total tPA dosage was 24 mg. Median time from injury to chest tube placement was 11 days and from chest tube placement to first tPA treatment was 4 days. No patients required a video-assisted thoracoscopy; however, 1 patient required thoracotomy. There were no deaths or bleeding complications attributed to intrapleural tPA. CONCLUSION: Although future studies are needed to identify optimum treatment guidelines, intrapleural tPA appears to be a safe and efficacious treatment option.

Perioperative supplementation with ascorbic acid does not prevent atrial fibrillation in coronary artery bypass graft patients.

BACKGROUND: Atrial fibrillation occurs after approximately 25% to 45% of coronary artery bypass graft (CABG) surgeries. Oxidative stress and related electrophysiological remodeling has been proposed as a potential cause of this atrial fibrillation. Perioperative supplementation of the antioxidant ascorbic acid has been evaluated as a preventive agent. The current investigation was conducted to evaluate the efficacy of ascorbic acid in reducing atrial fibrillation in CABG patients. METHODS: A prospective, randomized, placebo-controlled, triple-blind, single-institution study was conducted in nonemergency CABG patients. Subjects were monitored for episodes of arrhythmia and other complications. RESULTS: Eighty-nine treatment and 96 control subjects completed the study protocol. Demographics, comorbidities, and preoperative drugs were similar between groups. Surgical characteristics and postoperative medication use also were similar. The incidence of atrial fibrillation was 30.3% in the treatment group and 30.2% in the control group (P = .985). No difference was found in postoperative complications or mortality. CONCLUSIONS: Our data indicate that supplementation of ascorbic acid in addition to routine postoperative care does not reduce atrial fibrillation after coronary artery bypass grafting.

Tongue necrosis as an unusual presentation of carotid artery stenosis.

A 57-year-old man with premature coronary artery disease presented to the emergency department with left facial pain, numbness, and tongue swelling. The patient was found to have significant tongue necrosis, and subsequent arteriography demonstrated carotid bifurcation stenosis with embolization to the left lingual artery. The patient was successfully treated with debridement of his tongue and left carotid endarterectomy.
