PurposePoint-of-care ultrasound (POCU) is an evolving field in anesthesia. Therefore a systematic review of common diagnoses made by POCU during non-cardiac surgery was conducted. The information obtained from the review may be used to develop POCU curricula for the perioperative setting during non-cardiac surgery.SourceA systematic review was conducted for perioperative use of transthoracic /transesophageal echocardiography (TTE/TEE) in high-risk patients or in other patients experiencing periods of hemodynamic instability. The diagnoses included segmental wall motion abnormalities (SWMAs), low left ventricular ejection fraction (LVEF), hypovolemia, air embolism, cardiac/aortic thrombus, pulmonary embolus (PE), aortic valve disease, mitral valve disease, tricuspid valve disease, right ventricular (RV) failure, pericardial disease, and patent foramen ovale.Principal FindingsThree hundred twenty-one studies were found using our search terms, and thirteen studies were retained that met our inclusion criteria for review. The studies included 968 patients analyzed as either preoperative exams in high-risk patients (n = 568) or intraoperative exams during times of hemodynamic compromise/cardiac arrest (n = 400). The most common diagnoses in the preoperative exam group were low ejection fraction (25.4%), aortic valve disease (24.4%), mitral valve disease (20.0%), RV failure (6.6%), and hypovolemia (6.3%). In the intraoperative exam group, the most common diagnoses were hypovolemia (33.2%), low ejection fraction (20.5%), RV failure (13.1%), SWMAs (10.1%), and PE (5.8%).ConclusionIn this systematic review examining the use of TTE or TEE in non-cardiac surgery, the most frequent diagnoses were valvulopathy, low LVEF, hypovolemia, PE, SWMAs, and RV failure. This information should be used to inform evidence-based curricula for POCU in anesthesiology.
