ReviewTransesophageal echocardiography in the evaluation of the trauma patient: A trauma resuscitation transesophageal echocardiography exam.
The point-of-care ultrasound exam has become an essential tool for hemodynamic monitoring and resuscitation in the trauma bay as well as the intensive care unit. Transthoracic ultrasound provides a dynamic assessment of cardiac function, volume status, and fluid responsiveness that offers potential advantage over traditional methods of hemodynamic monitoring. More recently, a focused transthoracic echocardiography exam was described to improve immediate resuscitation of severely injured patients in the trauma bay. ⋯ TEE offers improved visualization of cardiac anatomy and physiology, improved diagnostic accuracy, and real-time assessment of intraoperative resuscitation progress, particularly in the operating room. This review discusses the fundamental principles of echocardiography as well as different ultrasound modes with their respective strengths and limitations. It reviews the current literature on the use of TEE in trauma, and suggests views for a trauma resuscitation transesophageal echocardiography exam (TREE), including sample images and videos.

Randomized Controlled TrialHeated humidified high-flow nasal cannula oxygen after thoracic surgery - A randomized prospective clinical pilot trial.
Thoracic surgery patients are at high-risk for adverse pulmonary outcomes. Heated humidified high-flow nasal cannula oxygen (HHFNC O2) may decrease such events. We hypothesized that patients randomized to prophylactic HHFNC O2 would develop fewer pulmonary complications compared to conventional O2 therapy. ⋯ Pulmonary complications were rare after thoracic surgery. Although HHFNC O2 did not convey significant benefits, these results need to be interpreted with caution, as our study was likely underpowered to detect a reduction in pulmonary complications. High rates of patient-reported discomfort with HHFNC O2 need to be considered in clinical practice and future trials.
