Ultrasound (US) performed at the point of care has found fertile ground in perioperative medicine. In the hands of anesthesiologists, transesophageal echocardiography (TEE) has become established as a powerful diagnostic and monitoring tool in the perioperative care of cardiac and non-cardiac patients. A number of point-of-care US (POCUS) applications are relevant to perioperative care, including airway, cardiac, lung and gastric US. Although guidelines exist to define the scope of practice for basic and advanced TEE, there remains a lack of such guidelines for perioperative point-of-care ultrasound (POCUS), despite a number of recent calls for action in the academic anesthesia community. POCUS training has been integrated into anesthesia residency curricula in Canada and the United States of America (USA). However, a nation-wide curriculum is still lacking. Many limitations to the development of perioperative POCUS curricula exist, including the need to define the scope of practice and design integrated longitudinal learning approaches. The main anesthesiologist societies in both the USA and Canada are promoting the development of guidelines and have introduced POCUS courses into their national conferences. Although bedside US imaging has been integrated into the curricula of many medical schools in North America, the need for specific national guidelines for the training and practice of POCUS in the perioperative setting by anesthesiologists is crucial to the further development of POCUS in perioperative medicine.

POCUS in perioperative medicine: a North American perspective.

Point-of-care ultrasound (POCUS) is becoming an integral part of anesthesia practice throughout the world. Despite the growing interest in POCUS among trainees and faculty, POCUS training is variable among universities across Canada. This suggests a need for curriculum development and standardization. International guidelines for Emergency Medicine and Critical Care have common frameworks and may be used as a reference to model anesthesia-specific curricula. The Royal College of Anaesthetists of the United Kingdom currently offers the only nationally approved POCUS curriculum for anesthesia and critical care trainees. Most curricula have in common a stepwise approach that consists of foundation of knowledge and skills and competency building through practice. Nevertheless, a significant variety of didactic modalities have been described, and online learning and simulation offer clear advantages. What constitutes the minimum number of studies necessary to achieve competence is still debated as are the most appropriate tools for assessment of POCUS competency.Availability of trained staff anesthesiologists remains a major limitation to curricula implementation in most centres. A National Curriculum should be modeled on the Competency By Design Approach, in line with the CanMEDS 2015 roles, and start with a focus on basic POCUS modalities and applications. Guidance for the training and certification of POCUS among practicing anesthesiologists is lacking.

Core point-of-care ultrasound curriculum: What does every anesthesiologist need to know?

The use of 3-dimensional (3D) transesophageal echocardiography (TEE) in perioperative evaluation of the mitral valve (MV) is increasing progressively, including the use of 3D MV models for quantitative analysis. However, the use of 3D MV models in clinical practice still is limited by the need for specific training and the long time required for analysis. A new stereoscopic visualization tool (EchoPixel True 3D) allows virtual examination of anatomic structures in the clinical setting, but its accuracy and feasibility for intraoperative use is unknown. The aim of this study was to assess the feasibility of 3D holographic display and evaluate 3D quantitative measurements on a volumetric MV image using the EchoPixel system compared with the 3D MV model generated by QLAB Mitral Valve Navigation (MVN) software.
