BACKGROUND: Drugs acting on the cardiovascular and central nervous system often display relatively fast clinical responses, which may differ in neonates compared to children and adults. Introduction of bedside monitoring tools might be of additional value in the pharmacodynamic (PD) assessment of such drugs in neonates. METHODS: We aim to provide an overview of the frequently used monitoring tools to assess drug effects on the hemodynamic status as well as the cerebral circulation, oxygenation and cerebral metabolism in neonates...

Training adult learners to use ultrasound in clinical practice relies on the ability of the learner to apply visuospatial concepts to the anatomy of the human body. We describe a visuospatial trainer that replicates the housing of an ultrasound transducer, through which a linear laser projects light in the same plane and orientation as the ultrasonic sound waves. We use this trainer in combination with a porcine heart dissection laboratory to teach bedside cardiac ultrasound and transthoracic echocardiography (TTE)...

BACKGROUND: The European Association of Cardiology (ESC) Guidelines on the diagnosis and treatment of acute heart failure (AHF) indicate prompt therapy initiation and performance of relevant investigations as paramount. Specifically, echocardiography prior to treatment is advocated only with hemodynamic instability, and the evaluation of clinical signs of peripheral perfusion and congestion is suggested as guidance for early interventions. Given the growing body of evidence on the diagnostic/monitoring capabilities of bedside ultrasound (including focused cardiac ultrasound, comprehensive echocardiography, lung ultrasound), we discuss the potential benefit of an integrated clinical/ultrasound approach at the very early stages of acute heart failure...

Traumatic ventral septal defect may be sustained after either blunt force or penetrating trauma to the chest. Severity ranges from asymptomatic to acute decompensated heart failure. Our patient suffered a stab wound to the chest and was initially taken to the operating room for repair of a lacerated right ventricle. Subsequent postoperative hemodynamic deterioration prompted a bedside transthoracic echocardiogram, which failed to identify causal factors. A transesophageal echocardiogram performed immediately after ventral septal defect was demonstrated...

PURPOSE: Point-of-care ultrasonography (POCUS) is a useful tool with multiple perioperative applications relevant to the anesthesiologist. Nevertheless, the full scope of POCUS applications has yet to be formally incorporated into Canadian anesthesiology training. The purpose of this study was to determine the current state of POCUS training in Canadian anesthesiology residency programs. METHODS: We conducted a web-based survey of program directors from Royal College-accredited anesthesiology residency programs across Canada...

BACKGROUND: The therapeutic decision to close patent ductus arteriosus in preterm infants entails great uncertainty. Near-infrared spectroscopy is a noninvasive bedside technique used to monitor mixed regional oxygen saturation. We hypothesized that near-infrared spectroscopy could identify preterm infants at risk of mesenteric hypoperfusion associated with hemodynamically significant ductus arteriosus. METHODS: This is a prospective observational study including consecutively admitted preterm infants with a gestational age <32 weeks...

A 73-year-old male was brought into hospital with chest pain and inferior ST elevation on ECG. The patient immediately proceeded to the catheter lab for primary percutaneous coronary intervention. Angiography did not identify any culprit lesions to account for the patient's electrocardiographic changes and ongoing symptoms of chest pain. Bedside echocardiography revealed critical aortic stenosis. Intra-aortic balloon pump (IABP) was inserted, resulting in resolution of chest pain and ST-segment changes. The patient underwent successful aortic valve (AV) replacement without the need for coronary intervention...

Calcified nodules in human coronary arteries are usually focally distributed. Non-invasive imaging of coronary arteries by bedside emergency transthoracic echocardiography in adults is possible and may become a useful adjunct to other methods of coronary artery examination. Coronary artery stenosis can be identified as localized color aliasing and accelerated flow velocities. Complete visualization of individual ostial coronary segments might ease the demonstration of coronary stenosis by bedside transthoracic echocardiography...

REVIEW
Xavier Monnet, Jean-Louis Teboul
BACKGROUND: For complex patients in the intensive care unit or in the operating room, many questions regarding their haemodynamic management cannot be answered with simple clinical examination. In particular, arterial pressure allows only a rough estimation of cardiac output. Transpulmonary thermodilution is a technique that provides a full haemodynamic assessment through cardiac output and other indices. MAIN BODY: Through the analysis of the thermodilution curve recorded at the tip of an arterial catheter after the injection of a cold bolus in the venous circulation, transpulmonary thermodilution intermittently measures cardiac output...

Functional echocardiography (fECHO) refers to a bedside, limited assessment of the ductus arteriosus, myocardial performance and pulmonary or systemic haemodynamics that is brief in nature and addresses a specific clinical question or management dilemma. This point-of-care ultrasonography is increasingly used internationally and locally among neonatal units to assist with management of neonatal haemodynamic conditions. This article intends to explain the modality, its indications, interpretation and implications for management, and how it impacts long-term outcomes, particularly in chronic lung disease for premature infants born before 32 weeks of gestation...

STUDY OBJECTIVE: Current guidelines recommend patients presenting with transient ischemic attack (TIA) undergo echocardiography to evaluate for a cardiac source. However, echocardiography is not available daily at many centers. We assessed the yield from early transthoracic echocardiography (TTE) in consecutive patients with TIA evaluated in an emergency department observation unit (EDOU) protocol. METHODS: This observational cohort study took place in an academic medical center from January 1, 2011 to July 31, 2013...

OBJECTIVE: Pulmonary embolism (PE) is a common diagnosis with significant mortality if not appropriately treated. The use of transthoracic echocardiography in patients with PE is common; however, its diagnostic capabilities in this use are unclear. With the increased use of ultrasonography in medical settings, it is important to understand the strengths and limitations of echocardiography for the diagnosis of PE. METHODS: We conducted a systematic review of PubMed, CINAHL, and EMBASE through 2016 for articles assessing the diagnostic accuracy of transthoracic echocardiography for PE...

Non-invasive imaging modalities integrate the clinical and laboratory diagnostic work-up of patients admitted in emergency department for chest pain. Transthoracic echocardiography is the first-line imaging tool because it is rapidly and widely available, bedside feasible and cost-effective. Even when a comprensive exam is not feasible, a fast focused ultrasound exam should be performed. Contrast enhanced computed tomography is an easily accessible tool with specific application in patients suspected for pulmonary embolism (PE) and acute coronary syndrome (ACS) according to the pre-test risk assessment and to the clinical status...

Persistent Left Superior Vena Cava (PLSVC) should be suspected if we find dilatation of coronary sinus. Sophisticated imaging is not always available in each health care provider. Transthoracic echocardiography (TTE) with agitated saline injections through the left and right antecubital veins provides a simple, and inexpensive, but effective study for a rapid bedside diagnosis of PSLVC.

BACKGROUND: Cerebral venous air embolism (CVAE) is a severe clinical condition related to unfavoured outcome in patients with neurological impairment. CVAE may occur secondary to arterial or venous interventions. A rare mechanism of CVAE is retrograde embolism that is characterized by gas flow in a direction opposite to that of the normal blood flow. CASE REPORT: A 69-year-old female was admitted to our hospital with shortness of breath and abdominal pain. Abdominal computed tomography (CT) revealed intramural gas in the bowel and free gas in the mesenteric veins and portal vein...
