Chest X Ray

Background: The emergency department usually takes a supine posteroanterior (PA) chest X-ray imaging in trauma patients. In some cases, pneumothorax is not seen in the chest X-ray because of the patient's position. These cases are called occult pneumothorax. Misdiagnosis of occult pneumothorax in the emergency department may lead to complications such as tension pneumothorax. This study aimed to update patients’ features with occult pneumothorax due to blunt or penetrating trauma. Methods: In this study, data of 615 thoracic trauma patients admitted to the emergency department between January 2008 and December 2010 were evaluated. In total, 157 patients had undergone both chest X-ray and chest computed tomography and were diagnosed with pneumothorax. Of the 157 patients, 52 were excluded due to some criteria. Data of 105 patient, including their characteristics, trauma types, accompanying traumas, etiology of the chest trauma, chest X-ray findings, and computed chest tomography results were recorded. Data obtained were compared with the results of similar studies conducted in the last 10 years. Chest computed tomography was considered the gold standard for the diagnosis of pneumothorax. Results: The mean patient age was 36.19 ± 14.74 years. Occult pneumothorax was detected in 8 of 105 patients, giving a 7.6% overall incidence of occult pneumothorax. A traffic accident was the most common cause of etiology. All occult pneumothorax cases were caused by blunt trauma, and tube thoracostomy was performed in all of them. No significant differences were found between pneumothorax and occult pneumothorax cases concerning the etiology, accompanied trauma, intervention types, and trauma reasons (p < 0.05). Conclusions: This study supports the incidence of occult pneumothorax reported in the literature. When a patient is admitted with thoracic trauma, a physician should carefully evaluate the patient through supine chest X-ray examination. Only one misdiagnosis in trauma patients can be lead to many unintentional clinical and forensic results.

Tip Position

ABSTRACT Introduction With blunt and penetrating trauma to the chest, warfighters and civilians frequently suffer from punctured lung (pneumothorax) and/or bleeding into the pleural space (hemothorax). Optimal management of this condition requires the rapid placement of a chest tube to evacuate as much of the blood and air as possible. Incomplete drainage of blood leading to retained hemothorax may be the result of the final tube tip position not being in contact with the blood collections. To address this problem, we sought to develop a “steerable” chest tube that could be accurately placed or repositioned into a specific desired position in the pleural space to assure optimal drainage. An integrated infusion cannula was added for the instillation of anticoagulants to maintain tube patency, thrombolytics for clot lysis, and analgesics for pain control if required. Materials and Methods A triple-lumen tube was designed to provide a channel for a pull-wire which was wound around an axle integrated into a small proximal handle and controlled by a ratcheted thumbwheel. Tension on the wire creates an arc on the tube that allows for positioning. In vitro testing focused on the relationship between the tension on the pull-wire and the resultant arc. Two adult cadavers and two anesthetized pigs were used to study the feasibility of accurate tube placement. After a brief training session, providers were asked to place tubes inferiorly along the diaphragm where blood was anticipated to accumulate or at the apex of the lung for pneumothorax. Success was determined with fluoroscopic images and was judged as a tube tip lying in the targeted position. Results The design was prototyped with an extruded polyvinyl chloride multilumen tube and a 3D printed tensioning handle. In vitro studies showed that one turn of the thumbwheel created 70° to 90° of arc of the tube. Cadaver and animal studies showed consistent success in the desired placement of the tube at or near the lateral diaphragm or in the apex. Attempts were also successful by surgical residents with minimal training. Conclusions Initial preliminary studies on a novel steerable chest tube have demonstrated the ability to appropriately position the tube in a desired location. The addition of an extendable cannula will allow for safe clot lysis or maintained tube patency. Additional studies are planned to confirm the benefit of this device in preventing retained hemothorax.

Background: Traumatic arterio-enteric fistula is predominantly seen after penetrating trauma with only 21 reported cases documented in the past 25 years. They may present in an acute or delayed manner with upper or lower gastrointestinal bleed. A detailed clinical examination with requisite imaging can help in detecting such injuries. Case Description: Case 1: A 20-year-old gentleman, presented with penetrating stab injury to the gluteal region with bleeding per rectum. Imaging revealed evidence of injury to the inferior rectal artery which was found to be communicating with the extraperitoneal portion of the rectum. He was managed with a combination of endovascular and open surgery with a successful outcome. Case 2: A 29-year-old gentleman, presented in a delayed manner 2 weeks after a gunshot wound to the gluteal region, which was managed operatively in another hospital. He developed a massive lower gastrointestinal bleed 2 weeks after presentation. Imaging revealed evidence of a pseudoaneurysm of the inferior gluteal artery which had a fistulous communication with the gastrointestinal tract leading to bleeding. It was managed by endovascular techniques successfully. Conclusion: Arterio-enteric fistulas following trauma are rare phenomena and they need a high index of suspicion for diagnosis. Once diagnosed, they can be managed based on their location and patient physiology by interventional techniques, surgery, or a combination of the two.

AbstractThe liver is the second most commonly involved solid organ (after spleen) to be injured in blunt abdominal trauma, but liver injury is the most common cause of death in such trauma. In patients with significant blunt abdominal injury, the liver is involved approximately 35 to 45% of the time. Its large size also makes it a vulnerable organ, commonly injured in penetrating trauma. Other than its position and size, the liver is surrounded by fragile parenchyma and its location under the diaphragm makes it vulnerable to shear forces during deceleration injuries. The liver is also a vascular organ made of large, thin-walled vessels with high blood flow. In severe hepatic trauma, hemorrhage is a common complication and uncontrolled bleeding is usually fatal. In fact, in patients with severe abdominal trauma, liver injury is the primary cause of death. This article reviews the clinical presentation of patients with liver injury, the grading system for such injuries that is most frequently used, and management of the patient with liver trauma.

Abstract Background Although damage control (DC) surgery is widely assumed to reduce mortality in critically injured patients, survivors often suffer substantial morbidity, suggesting that it should only be used when indicated. The purpose of this systematic review was to determine which indications for DC have evidence that they are reliable and/or valid (and therefore in which clinical situations evidence supports use of DC or that DC improves outcomes). Methods We searched 11 databases (1950–April 1, 2019) for studies that enrolled exclusively civilian trauma patients and reported data on the reliability (consistency of surgical decisions in a given clinical scenario) or content (surgeons would perform DC in that clinical scenario or the indication predicted use of DC in practice), construct (were associated with poor outcomes), or criterion (were associated with improved outcomes when DC was conducted instead of definitive surgery) validity for suggested indications for DC surgery or DC interventions. Results Among 34,979 citations identified, we included 36 cohort studies and three cross-sectional surveys in the systematic review. Of the 59 unique indications for DC identified, 10 had evidence of content validity [e.g., a major abdominal vascular injury or a packed red blood cell (PRBC) volume exceeding the critical administration threshold], nine had evidence of construct validity (e.g., unstable patients with combined abdominal vascular and pancreas gunshot injuries or an iliac vessel injury and intraoperative acidosis), and six had evidence of criterion validity (e.g., penetrating trauma patients requiring > 10 U PRBCs with an abdominal vascular and multiple abdominal visceral injuries or intraoperative hypothermia, acidosis, or coagulopathy). No studies evaluated the reliability of indications. Conclusions Few indications for DC surgery or DC interventions have evidence supporting that they are reliable and/or valid. DC should be used with respect for the uncertainty regarding its effectiveness, and only in circumstances where definitive surgery cannot be entertained.
