Ashoobi MA, Homaie Rad E, Rahimi R. Diagnostic performance of sonography in penetrating torso trauma: a systematic review and meta-analysis. Eur J Trauma Emerg Surg 2024:10.1007/s00068-024-02446-6. [PMID: 38261075 DOI: 10.1007/s00068-024-02446-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2023] [Accepted: 01/04/2024] [Indexed: 01/24/2024]
Abstract
BACKGROUND This systematic review investigates the diagnostic value of ultrasound in the evaluation of torso injuries following a penetrating trauma. METHODS We searched PubMed, Scopus, and WOS databases for related original articles until May 7, 2023, and extracted data related to diagnostic performance. The bivariate model and hierarchic summary receiver operating characteristic (HSROC) approach were used to calculate pooled diagnostic values. Cochrane Q test and I-squared were performed to evaluate heterogeneity. We assessed heterogeneity with meta-regression. RESULTS Seventeen studies were included, which involved a total number of 1866 patients. According to meta-analysis, sonography demonstrated a pooled sensitivity of 56% (45-67%) and specificity of 96% (94-97%), positive likelihood ratio (LR +) of 13.66 (8.03-23.23), and negative likelihood ratio (LR-) of 0.45 (0.35-0.59) for detecting abdominal injuries. In pericardial penetrating trauma, pooled sensitivity was 100% (45-100%), pooled specificity was 99% (96-100%), LR + was 136.7 (24.8-752.3), and LR- was 0.00 (0.00-1.22). For thoracic penetrating trauma, pooled sensitivity was 99% (93-100%) and specificity was 100% (98-100%). CONCLUSIONS Sonography demonstrated promising diagnostic value in the initial assessment of torso penetrating trauma, particularly in the thoracic and pericardial regions. However, the sensitivity of sonography is limited in abdominal penetrating trauma and a combination with other imaging modalities should be considered in these cases.

Abstract
BACKGROUND While the role of Extended Focused Assessment with Sonography in Trauma (eFAST) is well defined in the management of severe blunt trauma, its performance in injuries caused by stab wounds has been poorly assessed. METHODS Prospective single centre study which included all patients with stab wounds to the thorax or abdomen between December 2016 and December 2018. All patients underwent initial investigation with both eFAST and CT scan, except in cases of haemodynamic or respiratory instability, and in cases with a positive diagnosis by eFAST in which case surgery without CT scan was performed. RESULTS Of the 200 consecutive patients included, 14 unstable patients underwent surgery immediately after eFAST. In these 14 patients, 9 had cardiac tamponade identified by eFAST and all were confirmed by surgery. In the remaining 186 patients, the median time between eFAST and CT scan was 30 min (IQR 20-49 min). Test characteristics (including 95% CI) for eFAST compared with reference standard of CT scan for detecting pneumothorax were as follows: sensitivity 77% (54%-92%), specificity 93% (90%-97%), positive predictive value (PPV) 60% (49%-83%), negative predictive value (NPV) 97% (93%-99%). Test characteristics (including 95% CI) for eFAST compared with CT scan for detecting haemothorax were as follows: sensitivity 97% (74%-99%), specificity 96% (92%-98%), PPV 83% (63%-93%) and NPV 99% (96%-100%). Finally, test characteristics (including 95% CI) for eFAST compared with CT scan for detecting haemoperitoneum were as follows: sensitivity 75% (35%-97%), specificity 97% (93%-99%), PPV 55% (23%-83%) and NPV 99% (96%-99%). CONCLUSIONS In patients admitted with stab wounds to the torso, eFAST was not sensitive enough to diagnose pneumothorax and haemoperitoneum, but performed better in the detection of cardiac tamponade and haemothorax than the other injuries. More robust multicentre studies are needed to better define the role of eFAST in this specific population.

Abstract
Focused Assessment with Sonography in Trauma (FAST) exam is the standard of care for pericardial and abdominal free fluid detection in emergency medicine. Despite its life saving potential, FAST is underutilized due to requiring clinicians with appropriate training and practice. To aid ultrasound interpretation, the role of artificial intelligence has been studied, while leaving room for improvement in localization information and computation time. The purpose of this study was to develop and test a deep learning approach to rapidly and accurately identify both the presence and location of pericardial effusion on point-of-care ultrasound (POCUS) exams. Each cardiac POCUS exam is analyzed image-by-image via the state-of-the-art YoloV3 algorithm and pericardial effusion presence is determined from the most confident detection. We evaluate our approach over a dataset of POCUS exams (cardiac component of FAST and ultrasound), comprising 37 cases with pericardial effusion and 39 negative controls. Our algorithm attains 92% specificity and 89% sensitivity in pericardial effusion identification, outperforming existing deep learning approaches, and localizes pericardial effusion by 51% Intersection Over Union with ground-truth annotations. Moreover, image processing demonstrates only 57 ms latency. Experimental results demonstrate the feasibility of rapid and accurate pericardial effusion detection from POCUS exams for physician overread.

Abstract
BACKGROUND AND OBJECTIVE Point-of-care focused vascular ultrasound (FOVUS), an assessment of carotid artery plaque, predicts coronary artery disease in outpatients referred for coronary angiography. Our primary objective was to determine the diagnostic accuracy of sonographer-performed FOVUS to predict major adverse cardiac events (MACE) within 30 days among patients with suspected cardiac ischemia in the emergency department (ED). METHODS We conducted a prospective cohort study of patients with chest pain presenting to a tertiary care ED who had an electrocardiogram and cardiac troponin testing. The primary outcome was a composite of death, acute myocardial infarction, or re-vascularization at 30 days. A sonographer performed FOVUS scans in consenting eligible subjects. Emergency physicians, blinded to the sonographer FOVUS result, performed a second FOVUS on some subjects. RESULTS We recruited 326 subjects (age 62.1 ± 13.5 years; 166 (52%) men), 319 of whom completed an FOVUS scan by the sonographer. Of these, 198 (62%) had a positive FOVUS scan and 41 (13%) had a 30-day MACE. The sensitivity was 83% (95% CI 71-94%), specificity 41% (95% CI 36-47%), positive-likelihood ratio 1.41 (95% CI 1.19-1.68), and negative-likelihood ratio 0.41 (95% CI 0.23-0.75). Among 71 subjects also scanned by an emergency physician, the Kappa was 0.50 (95% CI 0.31-0.70), suggesting moderate agreement between sonographer and emergency physician on the determination of significant carotid plaque. CONCLUSIONS The presence of carotid plaque on sonographer-performed FOVUS is associated with 30-day MACE in ED patients presenting with chest pain. The prognostic performance of FOVUS is not sufficient to support its use as a stand-alone risk stratification tool in the ED. Future work should investigate FOVUS in conjunction with validated clinical decision rules for chest pain and the impact of enhanced training and quality improvement in the conduct of FOVUS by emergency physicians. REGISTRATION This study was registered at clinicaltrials.gov (NCT02947360).

Abstract
Background Although the Hybrid Emergency Room System (HERS) is a relatively novel method for treating severe trauma patients, there have been few reported cases of gunshot wound patients treated in HERS. Here we report our treatment of a unique gunshot wound case, with shock, in a HERS setting. Case presentation A 72-year-old male was transferred to our hospital due to a gunshot wound (GSW). He presented with left chest injuries and vital signs consistent with shock. While resuscitating the patient, including massive blood transfusion and surgery to control the damage, a subsequent computed tomography in HERS revealed the internal distribution of the birdshot and damage to the abdominal organs. Lower lobectomy of the left lung and laparotomy for gastrointestinal repair were performed. After a planned repeat operation and reconstruction of the left chest wall, he was discharged uneventfully. Conclusions HERS during resuscitation was useful for helping clinicians not only to find the bullets' distribution and judge the severity of injury caused by the gunshot, but also to develop subsequent therapeutic strategies for rescuing the gunshot wound patient from a life-threatening situation.

Abstract
Background: The use of focused assessment with sonography in trauma (FAST) enables clinicians to rapidly screen for injury at the bedsides of patients. Pre-hospital FAST improves diagnostic accuracy and streamlines patient care, leading to dispositions to appropriate treatment centers. In this study, we determine the accuracy of artificial intelligence model-assisted free-fluid detection in FAST examinations, and subsequently establish an automated feedback system, which can help inexperienced sonographers improve their interpretation ability and image acquisition skills. Methods: This is a single-center study of patients admitted to the emergency room from January 2020 to March 2021. We collected 324 patient records for the training model, 36 patient records for validation, and another 36 patient records for testing. We balanced positive and negative Morison's pouch free-fluid detection groups in a 1:1 ratio. The deep learning (DL) model Residual Networks 50-Version 2 (ResNet50-V2) was used for training and validation. Results: The accuracy, sensitivity, and specificity of the model performance for ascites prediction were 0.961, 0.976, and 0.947, respectively, in the validation set and 0.967, 0.985, and 0.913, respectively, in the test set. Regarding feedback prediction, the model correctly classified qualified and non-qualified images with an accuracy of 0.941 in both the validation and test sets. Conclusions: The DL algorithm in ResNet50-V2 is able to detect free fluid in Morison's pouch with high accuracy. The automated feedback and instruction system could help inexperienced sonographers improve their interpretation ability and image acquisition skills.

Abstract
ABSTRACTObjectivesPerforming an extended Focused Assessment with Sonography in Trauma (eFAST) exam is common practice in the initial assessment of trauma patients. The objective of this study was to systematically review the published literature on diagnostic accuracy of all components of the eFAST exam.MethodsWe searched Medline and Embase from inception through October 2018, for diagnostic studies examining the sensitivity and specificity of the eFAST exam. After removal of duplicates, 767 records remained for screening, of which 119 underwent full text review. Meta-DiSc™ software was used to create pooled sensitivities and specificities for included studies. Study quality was assessed using the Quality in Prognostic Studies (QUADAS-2) tool.ResultsSeventy-five studies representing 24,350 patients satisfied our selection criteria. Studies were published between 1989 and 2017. Pooled sensitivities and specificities were calculated for the detection of pneumothorax (69% and 99% respectively), pericardial effusion (91% and 94% respectively), and intra-abdominal free fluid (74% and 98% respectively). Sub-group analysis was completed for detection of intra-abdominal free fluid in hypotensive (sensitivity 74% and specificity 95%), adult normotensive (sensitivity 76% and specificity 98%) and pediatric patients (sensitivity 71% and specificity 95%).ConclusionsOur systematic review and meta-analysis suggests that e-FAST is a useful bedside tool for ruling in pneumothorax, pericardial effusion, and intra-abdominal free fluid in the trauma setting. Its usefulness as a rule-out tool is not supported by these results.

Abstract
Background The ability of focused assessment with sonography for trauma (FAST) to detect clinically significant hemorrhage in hypotensive injured patients remains unclear. We sought to describe the sensitivity and specificity of FAST using findings at laparotomy as the confirmatory test. Methods Patients from the Prospective Observational Multicenter Major Trauma Transfusion (PROMMTT) study that had a systolic blood pressure < 90mm Hg and underwent FAST were analysed. Results were compared with findings at laparotomy. A therapeutic laparotomy (T-LAP) was defined as an abdominal operation within 6 hours in which a definitive procedure was performed. The sensitivity and specificity of FAST were calculated. Results The cohort included 317 patients that underwent FAST (108 positive, 209 negative). T-LAP was performed in 69% (n=75) of FAST(+) patients and 22% (n=48) of FAST(−) patients. FAST had a sensitivity of 62% and specificity of 83%. Conclusions In our multicenter cohort, 22% of FAST(−) patients underwent T-LAP within 6 hours of admission. In hypotensive patients with a negative FAST, clinicians should still maintain a high index of suspicion for significant abdominal hemorrhage. Level of evidence Level IV.

Abstract
The emergency treatment of thoracic injuries varies of general conditions and modern warfare. However, there are no unified battlefield treatment guidelines for thoracic injuries in the Chinese People's Liberation Army (PLA). An expert consensus has been reached based on the epidemiology of thoracic injuries and the concept of battlefield treatment combined with the existing levels of military medical care in modern warfare. Since there are no differences in the specialized treatment for thoracic injuries between general conditions and modern warfare, first aid, emergency treatment, and early treatment of thoracic injuries are introduced separately in three levels in this consensus. At Level I facilities, tension pneumothorax and open pneumothorax are recommended for initial assessment during the first aid stage. Re-evaluation and further treatment for hemothorax, flail chest, and pericardial tamponade are recommended at Level II facilities. At Level III facilities, simple surgical operations such as emergency thoracotomy and debridement surgery for open pneumothorax are recommended. The grading standard for evidence evaluation and recommendation was used to reach this expert consensus.

Abstract
Shotgun injuries from a short distance (<3 m) may cause massive bleeding and tissue destruction. Only immediate aggressive (surgical) therapy prevents lethal outcome. We report about a 27-year-old patient, who was wounded on the left chest wall by a straight-cut shotgun from a short distance. In cases of this special traumatic pattern damage control measures are necessary. The measures should take place in preclinical emergency management (by the on-site emergency physician). We report about the emergency management from admission to our hospital and the following surgical treatment until discharge from the hospital.

Abstract
Nonoperative management of both blunt and penetrating injuries can be challenging. During the past three decades, there has been a major shift from operative to increasingly nonoperative management of traumatic injuries. Greater reliance on nonoperative, or "conservative" management of abdominal solid organ injuries is facilitated by the various sophisticated and highly accurate noninvasive imaging modalities at the trauma surgeon's disposal. This review discusses selected topics in nonoperative management of both blunt and penetrating trauma. Potential complications and pitfalls of nonoperative management are discussed. Adjunctive interventional therapies used in treatment of nonoperative management-related complications are also discussed. REPUBLISHED WITH PERMISSION FROM Stawicki SPA.

Abstract
The objective of this pilot study was to test the feasibility of automating the detection of abdominal free fluid in focused assessment with sonography for trauma (FAST) examinations. Perihepatic views from 10 FAST examinations with positive results and 10 FAST examinations with negative results were used. The sensitivity and specificity compared to manual classification by trained physicians was evaluated. The sensitivity and specificity (95% confidence interval) were 100% (69.2%-100%) and 90.0% (55.5%-99.8%), respectively. These findings suggest that computerized detection of free fluid on abdominal ultrasound images may be sensitive and specific enough to aid clinicians in their interpretation of a FAST examination.

Abstract
The management of gunshot wounds of the abdomen and extremities is evolving with centres who treat large volumes of such injuries tending to the application of a policy of selective non-operative management. This article discusses the management of gunshot wounds to the abdomen and extremities and reviews the evidence supporting these changing practices. Special situations such as wounding by shotguns or air rifles are also examined as are the special considerations needed when dealing with the gunshot injured pregnant women or in a child.

Abstract
PURPOSE OF REVIEW This article reviews the latest operative trauma surgery techniques and strategies, which have been published in the last 10 years. Many of the articles we reviewed come directly from combat surgery experience and may be also applied to the severely injured civilian trauma patient and in the context of terrorist attacks on civilian populations. RECENT FINDINGS We reviewed the most important innovations in operative trauma surgery; the use of ultrasound and computed tomography in the preoperative evaluation of the penetrating trauma patient, the use of temporary vascular shunts, the current management of military wounds, the use of preperitoneal packing in pelvic fractures and the management of the multiple traumatic amputation patient. SUMMARY The last 10 years of conflict has produced a wealth of experience and novel techniques in operative trauma surgery. The articles we review here are essential for the contemporary care of the severely injured trauma patient, whether they are card for in a level 1 trauma center or in a field hospital at the edge of a battlefield.

Abstract
OBJECTIVE Portable ultrasound is now used routinely in many ICUs for various clinical applications. Echocardiography performed by noncardiologists, both transesophageal and transthoracic, has evolved to broad applications in diagnosis, monitoring, and management of critically ill patients. This review provides a current update on focused critical care echocardiography for the management of critically ill patients. METHOD Source data were obtained from a PubMed search of the medical literature, including the PubMed "related articles" search methodology. SUMMARY AND CONCLUSIONS Although studies demonstrating improved clinical outcomes for critically ill patients managed by focused critical care echocardiography are generally lacking, there is evidence to suggest that some intermediate outcomes are improved. Furthermore, noncardiologists can learn focused critical care echocardiography and adequately interpret the information obtained. Noncardiologists can also successfully incorporate focused critical care echocardiography into advanced cardiopulmonary life support. Formal training and proctoring are important for safe application of focused critical care echocardiography in clinical practice. Further outcomes-based research is urgently needed to evaluate the efficacy of focused critical care echocardiography.

Abstract
ABSTRACT
We present the case of a 20-year-old man who was stabbed in the left chest and was diagnosed with a large pericardial effusion by focused emergency department (ED) ultrasonography. After placement of a left chest tube for presumed tension pneumothorax, the pericardial effusion had resolved. The patient's postinjury course was complicated by pericarditis and recurrent tamponade, which required repeated pericardiocentesis for management. This case illustrates the role of focused ED ultrasonography for diagnosis of pericardial effusion in penetrating trauma and the potential for delayed pericardial effusion and tamponade in such patients. Although the pathophysiology of delayed pericardial effusion is unclear, autoimmune postpericardiotomy syndrome has been proposed as the cause of this rare condition. Our case underscores the importance of close monitoring of patients with known or suspected pericardial injuries due to their potential for the development of lifethreatening complications.

Abstract
BACKGROUND With the progressive use of new diagnostic techniques, the management of penetrating abdominal stab wounds is changing. Most studies have been conducted in well-equipped trauma centers in developed countries, and there is a paucity of reports from general teaching hospitals with limited resources. We reviewed the assessment of anterior abdominal stab wounds in patients presenting to our hospital hoping to establish an evidence-based algorithm for managing such patients in busy general hospitals. METHODS The medical records of all 393 patients treated at our hospital for anterior abdominal stab wounds over a 7-year period were reviewed. Information regarding age, gender, site of the stab wound, management, and complications were analyzed. RESULTS Twenty-six patients with hemodynamic instability at presentation underwent urgent laparotomy (LAP); 24 (92.3 %) of those procedures were therapeutic. Local wound exploration (LWE) proved that 114 (31 %) of all hemodynamically stable patients had no abdominal fascia penetration and consequently could be discharged home from the emergency department (ED). A total of 253 patients were found to have fascial penetration, and all were admitted for repeat clinical assessments (RCA) and imaging studies. A total of 121 (48 %) of the patients underwent abdominal exploration with 102 (84 %) therapeutic LAP procedures. CONCLUSIONS Hemodynamic instability and evisceration should continue to prompt urgent LAP. For stable patients, a sequence of LWE followed by focused abdominal sonography for trauma and computed tomography scanning for unclear cases primed by RCA was found to be efficient in limiting hospital admissions and reducing the rate of non-therapeutic LAP.

Abstract
BackgroundFocussed assessment with sonography in trauma (FAST) has assumed a key role in the rapid non-invasive assessment of thoracoabdominal trauma and assists in decreasing disposition time. This study evaluates FAST's efficacy with respect to haemodynamic stability in a South African emergency department (ED).MethodsData were collected prospectively by four emergency medicine doctors trained in emergency ultrasonography. FAST scans were performed by one ED doctor and timings, scan result and disposition were recorded. Patient haemodynamic stability was assessed by the emergency doctor performing the scan; subjectively at the time of scanning and objectively using calculation of the shock index. All scan results were subsequently verified by a second ED doctor in a blinded fashion and by CT scanning or operative intervention when clinically indicated.Results166 FAST scans were conducted of which 36 (21.7%) were positive. Mean age was 30.6 years (SD 12.8). 74.1% of patients sustained blunt traumatic injury. Doctors’ subjective haemodynamic stability assessments had higher specificity, sensitivity and predictive values than shock index alone. Haemodynamic instability and a positive FAST result were significantly related (p=0.004). Sensitivities and specificities of FAST scans for blunt and penetrating trauma were 93.1% and 100%, and 90.0% and 100%, respectively. Corresponding values for pneumothoraces were 84.6% and 100%.DiscussionThis study showed a valuable role for FAST in all traumas, particularly in haemodynamic compromise. As an addition to the physician's repertoire of bedside assessment tools, it improves diagnostic capabilities in comparison with simple haemodynamic assessments alone.

Abstract
OBJECTIVE We investigated our 12-year experience of traumatic diaphragmatic injury (TDI) in our emergency medical center. This study aimed to clarify clinical features of TDI and identify factors affecting mortality and morbidity in TDI treatment. METHODS We analyzed clinical characteristics, Injury Severity Score (ISS), probability of survival (Ps), and mortality of patients treated for TDI at the Tertiary Emergency Medical Center of Tokyo Metropolitan Bokutoh Hospital between January 1999 and December 2010. RESULTS TDI occurred in 28 patients. Of 21 TDI patients (75 %) who underwent surgery, 2 died (operative mortality, 9.5 %). Seven (25 %) presented with cardiopulmonary arrest, and TDI was detected during thoracotomy in the emergency room; all of these patients died. Blunt TDI occurred in 12 patients; penetrating TDI in 16. Blunt trauma patients had significantly more injured organs (3.75 ± 0.28, P = 0.043), higher ISS (P = 0.024), and lower Ps (P = 0.048). Lengths of intensive care unit (ICU) stay and hospital stay were greater in blunt cases than in penetrating cases (P = 0.004 and P = 0.02, respectively). Non-survivors had significantly higher ISS (P < 0.001), lower Ps (P = 0.0025), and larger injured diaphragm size (8.44 ± 1.97, P = 0.048). In blunt cases, delays in diagnosis and repair of TDI led to significantly increased ICU stay (16.25 ± 3.64, P = 0.017). CONCLUSION TDI occurs in cases of multiple trauma. Higher ISS and lower Ps predict death; therefore, prompt diagnosis of TDI and immediate repair of diaphragmatic injury are important.

Abstract
PURPOSE OF REVIEW The use of ultrasound for the management of the injured patient has expanded dramatically in the last decade. The focused assessment with sonography for trauma (FAST) has become one of the fundamental skills incorporated into the initial evaluation of the trauma patient. However, there are significant limitations of this diagnostic modality as initially described. Novel ultrasound examinations of the injured patient, although useful, must also be considered carefully. RECENT FINDINGS Increasing evidence supports the high specificity of FAST for detecting a pericardial effusion and intra-abdominal free fluid (hemorrhage) in the patient with blunt injury. On the other hand, a so-called negative FAST result still requires further diagnostic work up given its low sensitivity. Similarly, the role of FAST in penetrating abdominal trauma appears to be limited because of lower sensitivity for visceral injury compared to other modalities. Extended FAST (EFAST), that adds a focused thoracic examination, has high accuracy for the detection of pneumothorax comparable to computed tomographic scan, the significance of which is not currently known. Finally, the utility of intensivist-performed ultrasound in the ICU is expanding to limited hemodynamic assessment and facilitation of central venous catheter placement. SUMMARY The indications for FAST and additional ultrasound studies in the injured patient continue to evolve. Application of sound clinical evidence will avoid unsubstantiated indications for ultrasound to creep into our clinical practice.

Abstract
STUDY OBJECTIVE A recent Cochrane Review has demonstrated that emergency ultrasonography decreases the amount of computerised tomographic scans in blunt abdominal trauma.13 However, there is no systematic review that has evaluated the utility of the Focused Assessment with Sonography for Trauma(FAST) exam in penetrating torso trauma. We systematically reviewed the medical literature for the utility of the FAST exam to detect free intraperitoneal blood after penetrating torso trauma. METHODS We searched PUBMED and EMBASE databases for randomised controlled trials from 1965 through December 2009 using a search strategy derived from the following PICO formulation of our clinical question: PATIENTS patients (12+ years) sustaining penetrating trauma to the torso. INTERVENTION FAST exam during their initial trauma workup. Comparator: either local wound exploration (LWE),computerised tomography (CT), diagnostic peritoneal lavage (DPL), or laparotomy. OUTCOME intraperitoneal and pericardial free fluid. The methodological quality of the studies was assessed.Qualitative methods were used to summarise the study results. ANALYSIS Sensitivities and specificities were compared using a Forest Plot (95% CI) calculated by Revman 5 (Review Manager Version 5.0. Copenhagen: The Nordic Cochrane Centre, The Cochrane Collaboration,2008) between the FAST exam and definitive diagnostic modalities such as LWE, CT, DPL, or laporotomy. RESULTS We identified eight observational studies (n=565 patients) that met our selection criteria. The prevalence of a positive FAST exam after penetrating trauma was fairly low ranging from 24.2% to 56.3%.The FAST exam for penetrating trauma is a highly specific (94.1–100.0%), but not very sensitive (28.1–100%) diagnostic modality. CONCLUSION From the review of the literature, a positive FAST exam has a high incidence of intraabdominal injury and should prompt an exploratory laparotomy. However, a negative initial FAST exam after penetrating trauma should prompt further diagnostic studies such as LWE, CT, DPL, or laparotomy.

Abstract
OBJECTIVES Chest X-ray (CXR), abdominal ultrasound, cardiac ultrasound, and abdominal X-ray are the most frequently used imaging modalities to radiologically evaluate patients with penetrating torso trauma. The aim of this study was to evaluate the accuracy of these imaging modalities. METHODS From January 2001 until January 2005, all consecutive patients with penetrating torso injuries presenting at the emergency department of a level 1 trauma center were included. Imaging modalities (chest/abdominal X-ray, abdominal/cardiac ultrasound), were compared retrospectively with a 'gold standard' (i.e. computed tomography or surgery within 2 h after arrival) or outcome of conservative treatment. The accuracy of the imaging modalities was calculated. RESULTS Three hundred and eighteen patients were included. On the basis of 299 CXRs, the sensitivity for diagnosing pneumothorax, hemothorax, and subcutaneous emphysema was 71, 63, and 61%, respectively. The sensitivity of abdominal ultrasound (N = 229) to detect free abdominal fluid and/or intra-abdominal injury was 65%. The specificity, positive predictive value, negative predictive value, and accuracy of the two imaging modalities to detect any of the diagnoses mentioned were >or=87%. Cardiac ultrasound (N = 31) did not show any false positive or negative results for detecting cardiac effusion. Pneumoperitoneum was not seen on abdominal X-ray in eight of 11 patients with perforation of a hollow organ. CONCLUSION Despite high specificity, positive predictive value, and negative predictive value, a considerable number of lesions remain undetected after CXR and abdominal ultrasound because of moderate-to-inadequate sensitivity. Abdominal X-ray hardly provides additional information. Careful clinical monitoring of patients is mandatory, particularly when computed tomography scan or operative treatment is not indicated.

Abstract
Ultrasonography used by practicing clinicians has been shown to be of utility in the evaluation of time-sensitive and critical illnesses in a range of environments, including pre-hospital triage, emergency department, and critical care settings. The increasing availability of light-weight, robust, user-friendly, and low-cost portable ultrasound equipment is particularly suited for use in the physically and temporally challenging environment of a multiple casualty incident (MCI). Currently established ultrasound applications used to identify potentially lethal thoracic or abdominal conditions offer a base upon which rapid, focused protocols using hand-carried emergency ultrasonography could be developed. Following a detailed review of the current use of portable ultrasonography in military and civilian MCI settings, we propose a protocol for sonographic evaluation of the chest, abdomen, vena cava, and extremities for acute triage. The protocol is two-tiered, based on the urgency and technical difficulty of the sonographic examination. In addition to utilization of well-established bedside abdominal and thoracic sonography applications, this protocol incorporates extremity assessment for long-bone fractures. Studies of the proposed protocol will need to be conducted to determine its utility in simulated and actual MCI settings.

Abstract
UNLABELLED Selective non-operative management based on clinical assessment has been shown to be a generally safe approach in the management of penetrating stab wounds of the torso. However there will be a subset of patients who fail selective non-operative management. This audit focuses on the failures. METHODS The metropolitan surgical service in Pietermaritzburg covers 3 hospitals. At the weekly metropolitan morbidity and mortality meeting all trauma patients are reviewed. All cases of failed selective non-operative management of penetrating abdominal stab wounds are discussed. Failed non-operative management is usually defined as any patient who ultimately requires surgical exploration. We do not subscribe to this as we feel as long as the need for surgical intervention is recognised within a short period of time (<12h) there is little additional morbidity. Recognition of the need for surgical intervention after 12h would be regarded by us as failed non-operative management as we feel the risk of delay associated morbidity begins to increase significantly after this time. RESULTS A total of 340 patients with a penetrating anterior abdominal stab wound were managed over the 2 year period under review. A total of 192 (56%) of these patients were subjected to mandatory laparotomy. Of these mandatory laparotomies 98% were positive. The remaining 148 (44%) patients were observed. Of the 148 observed patients a total of 30 (20%) subsequently underwent surgery. A total of 13 patients were only taken to surgery after 12h of observation. In this group of 13 patients the average delay between admission and recognition of injury was 40 h. There were six gastric injuries, one pyloric and pancreatic injury, two gallbladder injuries, one liver, one colon and two small bowel injuries. There were no deaths. 9 patients recovered with no additional morbidity. In the remainder, morbidity included, relaparotomy (1), open abdomen (1), renal failure (1) and prolonged stay in ICU (3). CONCLUSION Clinical assessment accurately predicts the need for mandatory laparotomy following a stab wound to the torso. In patients who do not meet the indications for mandatory laparotomy and who are subjected to non-operative management 20% will come to surgery. A subgroup may only be recognised as requiring surgery after more than 12h. These patients are at risk of delay associated morbidity. There are particular anatomical sites and structures which are prone to error.

Abstract
BACKGROUND Pulseless electrical activity (PEA) secondary to both blunt and penetrating trauma is associated with minimal survival. The pericardial view of the focused abdominal sonography for trauma (p-FAST) can differentiate between patients with and without organized cardiac activity and may assist in the decision to terminate ongoing resuscitation. METHODS A retrospective review was performed for all patients presenting to a level I trauma center from January 2006 through January/2009 who had PEA on arrival or developed PEA in the emergency department. Additional data abstracted included outcome, the p-FAST findings, and mechanism of injury. Recorded FAST examinations were reviewed by a blinded ultrasound trained physician. RESULTS During the study period 25 patients presented with PEA and three developed PEA during initial resuscitation. Contractile cardiac activity was present in nine patients with PEA on presentation and immediately after deterioration to PEA in the three patients developing PEA. Four patients had a penetrating mechanism and 24 were blunt. Two pericardial effusions were present on examination, both after blunt trauma. Three patients survived beyond the emergency department (89% early mortality). The survivors had presented in PEA with organized cardiac contractile activity on ultrasound and had tension pneumothorax, tension hemothorax, and hypovolemia treated. Two patients died in the operating room of uncontrolled hemorrhage and one patient died 6 days after admission because of closed head injury. CONCLUSIONS The presence of PEA at any time during initial resuscitation is a grave prognostic indicator. p-FAST is a useful test to identify contractile cardiac activity. p-FAST may identify those patients with potential for survival.

Abstract
Point-of-care ultrasound is well suited for use in the emergency setting for assessment of the trauma patient. Currently, portable ultrasound machines with high-resolution imaging capability allow trauma patients to be imaged in the pre-hospital setting, emergency departments and operating theatres. In major trauma, ultrasound is used to diagnose life-threatening conditions and to prioritise and guide appropriate interventions. Assessment of the basic haemodynamic state is a very important part of ultrasound use in trauma, but is discussed in more detail elsewhere. Focussed assessment with sonography for Trauma (FAST) rapidly assesses for haemoperitoneum and haemopericardium, and the Extended FAST examination (EFAST) explores for haemothorax, pneumothorax and intravascular filling status. In regional trauma, ultrasound can be used to detect fractures, many vascular injuries, musculoskeletal injuries, testicular injuries and can assess foetal viability in pregnant trauma patients. Ultrasound can also be used at the bedside to guide procedures in trauma, including nerve blocks and vascular access. Importantly, these examinations are being performed by the treating physician in real time, allowing for immediate changes to management of the patient. Controversy remains in determining the best training to ensure competence in this user-dependent imaging modality.

Abstract
Coronary artery injuries are rare but highly lethal. Debate exists as to the best treatment for this complex set of injuries, with historical treatment favoring arterial ligation. Although conventional coronary artery bypass grafting using cardiopulmonary bypass has been used somewhat successfully, enthusiasm for off-pump CABG (OPCAB) has grown more recently. We report two unique cases of left anterior descending coronary arterial injuries managed successfully with OPCAB.

Abstract
BACKGROUND Traumatic injury is a leading cause of morbidity and mortality in developed countries worldwide. Recent studies suggest that many deaths are preventable if injuries are recognized and treated in an expeditious manner - the so called 'golden hour' of trauma. Ultrasound revolutionized the care of the trauma patient with the introduction of the FAST (Focused Assessment with Sonography for Trauma) examination; a rapid assessment of the hemodynamically unstable patient to identify the presence of peritoneal and/or pericardial fluid. Since that time the use of ultrasound has expanded to include a rapid assessment of almost every facet of the trauma patient. As a result, ultrasound is not only viewed as a diagnostic test, but actually as an extension of the physical exam. METHODS A review of the medical literature was performed and articles pertaining to ultrasound-assisted assessment of the trauma patient were obtained. The literature selected was based on the preference and clinical expertise of authors. DISCUSSION In this review we explore the benefits and pitfalls of applying resuscitative ultrasound to every aspect of the initial assessment of the critically injured trauma patient.

Abstract
In German-speaking countries, most serious thoracic injuries are attributable to the impact of blunt force; they are the second most frequent result of injury after head injury in polytrauma patients with multiple injuries. Almost one in every three polytraumatized patients with significant chest injury develops acute lung failure, and one in every four, acute circulatory failure. The acute circulatory arrest following serious chest injury involves a high mortality rate, and in most cases it reflects a tension pneumothorax, cardiac tamponade, or hemorrhagic shock resulting from injury to the heart or one of the large vessels close to it. Brisk drainage of tension pneumothorax and adequate volume restoration are therefore particularly important in resuscitation of multiply traumatized patients, as are rapid resuscitative thoracotomy to allow direct heart massage, drainage of pericardial tamponade, and control of hemorrhage. However the probability of survival described in the literature is very low for patients sustaining severe chest trauma with acute cardiac arrest. The case report presented here describes a female polytrauma patient who suffered an acute cardiac arrest following cardiac tamponade after admission in the emergency department and who survived without neurological deficits after an emergency thoracotomy. Selections from the topical literature can help the treating physician in the emergency department in making decisions on whether an emergency thoracotomy is indicated after a blunt chest injury and on the procedure itself.

Abstract
Abstract
Background
In patients with penetrating abdominal injury (PAI), haemodynamic instability and peritonitis are indications for laparotomy, but it remains uncertain whether laparotomy is indicated for evisceration, retained foreign body and pneumoperitoneum. In 1989, a review of 107 patients with PAI revealed a 78·5 per cent laparotomy rate, with 35 per cent considered unnecessary. The aim of this study was to review current practice in the same hospitals.
Methods
A retrospective review included case notes from 224 patients with PAI presenting to three hospitals between 2001 and 2005.
Results
Some 206 patients (92·0 per cent) were male and the mean age was 30·5 years. Aetiologies were stabbing (96·4 per cent), impalement (2·7 per cent) and gunshot wound (0·9 per cent). Laparotomy was performed in 48 patients (21·4 per cent), and was positive in 33 and unnecessary or negative in 15. Haemodynamic instability and peritonitis were strong indicators of positive laparotomy; seven of 13 laparotomies for evisceration alone were negative, as were two of four for retained foreign bodies.
Conclusion
The laparotomy rate fell from 78·5 to 21·4 per cent over 25 years. The rate of unnecessary or negative laparotomy did not change. Isolated evisceration and retained foreign body remain relative indications.

Abstract
OBJECTIVES Australasian trauma centres receive relatively low numbers of penetrating injuries from stabbings. There is limited agreement regarding protocols to guide the management of haemodynamically stable patients with penetrating injuries. This has resulted in a wide variation in practice with anecdotally high negative laparotomy rates. The aim of the present study was to review the ED procedures, investigations and disposition of this group of patients. METHODS A retrospective review of all patients presenting with abdominal penetrating injury was undertaken over a 5 year period. Data on demographics, presenting features and management were collected. RESULTS There were 109 patients who were haemodynamically stable (systolic blood pressure > 90) on arrival to the trauma centre. Diagnostic ED procedures and investigations consisted of wound exploration in 47 (43.1%) patients, focused abdominal sonography in trauma in 44 (40.4%) patients and a CT abdomen in 36 (33.0%) of patients. The sensitivity for focused abdominal sonography in trauma and CT when used together was 77.8%. There were 39 laparotomies performed with a negative laparotomy rate of 23.1%. There were 10 laparoscopies performed, none went on to require a laparotomy. Patients undergoing negative laparotomies spent significantly longer times in hospital than patients managed conservatively or those undergoing laparoscopies. CONCLUSIONS The number of penetrating abdominal injuries remains low. Imaging alone cannot reliably exclude intraperitoneal injury. A greater utilization of ED wound exploration and laparoscopy based on agreed guidelines could improve management. An algorithm for the management of these patients is suggested.

Abstract
Traumatic death remains pandemic. The majority of preventable deaths occur early and are due to injuries or physiologic derangements in the airway, thoracoabdominal cavities, or brain. Ultrasound is a noninvasive and portable imaging modality that spans a spectrum between the physical examination and diagnostic imaging. It allows trained examiners to immediately confirm important syndromes and answer clinical questions. Newer technologies greatly increase the fidelity, accessibility, ease of use, and informatic manipulation of the results. The early bedside use of focused ultrasound as the initial imaging modality used to detect hemoperitoneum and hemopericardium in the resuscitation of the injured patient has become an accepted standard of care. Widespread dissemination of basic ultrasound skills and technology to facilitate this brings ultrasound to many resuscitative and critical care areas. Although not as widely appreciated, the focused use of ultrasound may also have a role in detecting hemothoraces and pneumothoraces, guiding airway management, and detecting increased intracranial pressure. Intensivists generally utilize a treating philosophy that requires the real-time integration of many divergent sources of information regarding their patients' anatomy and physiology. They are therefore positioned to take advantage of focused resuscitative ultrasound, which offers immediate diagnostic information in the early care of the critically injured.

Abstract
The management of penetrating injuries to the abdomen has evolved back to a selective nonoperative approach. Using clinical examination for screening, evaluable patients without hemodynamic instability or peritonitis can safely undergo a trial of nonoperative management. For stab wounds, this involves serial clinical examination with delayed laparoscopic evaluation of the diaphragm for left thoracoabdominal injuries and CT scanning for suspected solid-organ injuries. The same contraindications to nonoperative management apply to gunshot injuries. Gunshot injuries undergoing nonoperative management require detailed trajectory imaging with CT. The presence of peritoneal violation without definite organ injury requires serial clinical examination. Isolated solid-organ injury is not an absolute contraindication to nonoperative management and may benefit from advanced endovascular and percutaneous interventions to facilitate management. Selective nonoperative management of both stab wounds and gunshot injuries is safe and has been shown to decrease the rate of unnecessary laparotomy, length of hospital stay, and management costs.

Abstract
Ultrasound imaging enhances the physician's ability to evaluate, diagnose, and treat emergency department (ED) patients. Because ultrasound imaging is often time-dependent in the acutely ill or injured patient, the emergency physician is in an ideal position to use this technology. Focused ultrasound examinations provide immediate information and can answer specific questions about the patient's physical condition. We report a case in which blunt trauma to the abdomen and pre-existing pericardial fluid, due to human immunodeficiency virus (HIV), caused pericardial tamponade, diagnosed by bedside ultrasonography, and subsequent cardiac arrest. An ED thoracotomy released this tamponade, and spontaneous cardiac activity returned. The indications for and efficacy of ED thoracotomy have been debated for many years. Multiple studies have shown that patients with isolated penetrating chest trauma have the best outcome and that patients with blunt trauma without signs of life at the scene or in the ED have the poorest. We demonstrate the importance of ultrasound use by emergency physicians to assess trauma patients with pulseless electrical activity and suggest that in specific clinical situations after blunt trauma, an ED thoracotomy can be life saving.

Abstract
BACKGROUND Previous studies have concentrated on the accuracy of Focused Assessment with Sonography in Trauma (FAST), but evaluation of whether FAST changes subsequent management has not been fully assessed. METHODS This prospective study compared 419 trauma admissions in two groups, FAST and no-FAST, for demographics, time of resuscitation, and action after resuscitation. The 194 patients undergoing FAST had their management plan specified before, and confirmed after, FAST was performed to assess for change in management. To ensure scan consistency and to minimize bias, criteria were established to define an adequate FAST. RESULTS FAST was performed in 194 patients (46%), assessing for free fluid. Management was changed in 59 cases (32.8%) after FAST. Laparotomy was prevented in 1 patient, computed tomography was prevented in 23 patients, and diagnostic peritoneal lavage was prevented in 15 patients. Computed tomography rates were reduced from 47% to 34% and diagnostic peritoneal lavage rates were reduced from 9% to 1%. CONCLUSIONS FAST plays a key role in trauma, changing subsequent management in an appreciable number of patients.

Abstract
BACKGROUND The modern management of penetrating abdominal trauma has decreased the incidence of unnecessary laparotomy by using selective non-operative management protocols. However, the real benefits of physical examination and different diagnostic methods are still unclear. METHODS From January 2000 to April 2003, we prospectively collected data on 117 patients with penetrating stab wounds to the thoracoabdominal, anterior abdominal, and back regions who had non-operative management. Clinical examination was the primary tool to differentiate those patients requiring operation. Findings of physical examination, ultrasound, computed tomography, endoscopy, echocardiography, diagnostic peritoneal lavage, and diagnostic laparoscopy were reviewed. The number of therapeutic, non-therapeutic, and negative laparotomies were recorded. RESULTS Non-operative management was successful in 79% of patients. There were 11 early (within 8 hours of admission) and 14 delayed (more than 8 hours after admission) laparotomies performed, depending on the results of various diagnostic procedures. Non-operative management failed in 21% of patients, and the rate of non-therapeutic laparotomy in early and delayed laparatomy groups was 9% and 14% respectively. There was no negative laparatomy. CONCLUSIONS The use of physical examination alone and/or together with different diagnostic methods allows reduction of non-therapeutic laparotomies and elimination of negative laparatomies.

Abstract
Thoracic trauma is one of the leading causes of death in all age groups and accounts for 25-50% of all traumatic injuries. While the majority of patients with thoracic trauma can be managed conservatively, a small but significant number requires emergency thoracotomy as part of their initial resuscitation. The procedure has been advocated for evacuation of pericardial tamponade, direct control of intrathoracic haemorrhage, control of massive air-embolism, open cardiac massage and cross-clamping of the descending aorta. Emergency thoracotomy can be defined as thoracotomy "occurring either immediately at the site of injury, or in the emergency department or operating room as an integral part of the initial resuscitation process". Following emergency thoracotomy, the overall survival rates for penetrating thoracic trauma are around 9-12% but have been reported to be as high as 38%. The survival rate for blunt trauma is approximately 1-2%. The decision to perform emergency thoracotomy involves careful evaluation of the scientific, ethical, social and economic issues. This article aims to provide a review of the current literature and to outline the pathophysiological features, technical manoeuvres and selective indications for emergency thoracotomy as a component of the initial resuscitation of trauma victims with thoracic injury.

Abstract
BACKGROUND AND OBJECTIVE Handheld ultrasound, because of its light weight, size, rugged design, and relative simplicity of use is ideal for use on operational military deployment. These machines have been used in the diagnosis of a range of traumatic conditions including abdominal, thoracic, and extremity trauma in the hospital environment, yet few data exist on their use during military operations. This paper presents experience of handheld focused assessment with sonography for trauma (FAST) on operational military deployment. METHOD Over a two month period, handheld FAST was performed by a single surgeon during the circulation phase of the primary survey in trauma patients presenting to the British Military Hospital in Iraq. RESULTS Fifteen from casualties underwent a FAST examination. Ten were victims of blunt trauma, two had received injuries anti-personnel mines, and three had penetrating injuries from ballistic trauma. There was one positive FAST, confirmed at laparotomy as bleeding from a liver injury. Thirteen scans were negative and remained negative on repeat FAST at 6 hours. One further patient with a negative FAST underwent laparotomy because of transectory, there was no intra-abdominal blood or fluid at surgery. CONCLUSION Handheld FAST is a valuable technique for investigating abdominal or thoracic bleeding in single or multiple casualty events on operational military deployment.
