Penetrating and blunt force mechanisms frequently result in thoracic trauma. Thoracic injuries cover the spectrum from trivial to lethal, and more than half are associated with head, abdomen or extremity trauma. Fortunately over eighty percent of injuries can be managed non-operatively utilizing tube thoracostomy, appropriate analgesia and aggressive respiratory therapy. Patients requiring emergency thoracotomy are either in shock or have life threatening injuries and, as expected, have significant mortality and morbidity. Injury to the thorax directly accounts for approximately 25% of trauma related mortality and is a contributing factor in another 25%. Early mortality results from haemorrhage, catastrophic injury or associated head or abdominal trauma. Not unexpectedly, late deaths are related to sepsis and organ failure. Blunt injury to the thorax most commonly results from motor vehicle collisions, with motorcycle accidents, pedestrians struck and falls next in frequency. Stab wound and gunshot wounds comprise the vast majority of penetrating injuries. In general the mortality from penetrating injury is higher and related to vascular injury and shock. Mortality from blunt trauma often results from abdominal and, especially, head injury. Rapid assessment and interventions, such as tube thoracostomy and airway control, can be life saving. The patient's haemodynamic status drives early treatment, often necessitating emergency surgery. Detailed imaging studies are reserved for haemodynamically stable patients. The evaluation and treatment of specific thoracic injuries will be discussed, as well as some general principles in treating thoracic trauma.
Background Ventilator-associated pneumonia (VAP) is a serious complication of mechanical ventilation. We sought to investigate factors associated with the development of VAP in critically ill trauma patients. Methods We conducted a retrospective review of trauma patients admitted to our trauma intensive care unit between 2016 and 2018. Patients with ventilator-associated pneumonia were identified from the trauma database. Data collected from the trauma database included demographics (age, gender and race), mechanism of injury (blunt, penetrating), injury severity (injury severity score ''ISS''), the presence of VAP, transfused blood products and presenting vital signs. Results A total of 1403 patients were admitted to the trauma intensive care unit (TICU) during the study period; of these, 45 had ventilator-associated pneumonia. Patients with VAP were older (p = 0.030), and they had a higher incidence of massive transfusion (p = 0.015) and received more packed cells in the first 24 h of admission (p = 0.028). They had a higher incidence of face injury (p = 0.001), injury to sternum (p = 0.011) and injury to spine (p = 0.024). Patients with VAP also had a higher incidence of acute kidney injury (AKI) (p \ 0.001) and had a longer ICU (p \ 0.001) and hospital length of stay (p \ 0.001). Multiple logistic regression models controlling for age and injury severity (ISS) showed massive transfusion (p = 0.017), AKI (p \ 0.001), injury to face (p \ 0.001), injury to sternum (p = 0.007), injury to spine (p = 0.047) and ICU length of stay (p \ 0.001) to be independent predictors of VAP. Conclusions Among critically ill trauma patients, acute kidney injury, injury to the spine, face or sternum, massive transfusion and intensive care unit length of stay were associated with VAP.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
