Abstract
Purpose To assess whether pre-operative focused cardiac ultrasound and lung ultrasound screening performed by a junior doctor can change diagnosis and clinical management of patients aged ≥65 years undergoing emergency, non-cardiac surgery. Method This pilot prospective observational study included patients scheduled for emergency, non-cardiac surgery. The treating team completed a diagnosis and management plan before and after focused cardiac and lung ultrasound, which was performed by a junior doctor. Changes to diagnosis and management after ultrasound were recorded. Ultrasound images were assessed for image and diagnostic interpretation by an independent expert. Results There was a total of 57 patients at age 77 ± 8 years. Cardiopulmonary pathology was suspected after clinical assessment in 28% vs. 72% after ultrasound (including abnormal haemodynamic state in 61%, valvular lesions in 32%, acute pulmonary oedema/interstitial syndrome in 9% and bilateral pleural effusions in 2%). In 67% of patients, the perioperative management was changed. The changes were in fluid therapy in 30%, cardiology consultation in 7%, formal in- or out-patient, transthoracic echocardiography in 11% and 30% respectively. Discussion The impact of pre-operative focused cardiac and lung ultrasound on diagnosis and management of patients on the hospital ward before emergency non-cardiac surgery by a junior doctor was comparable to previous studies of anaesthetists experienced in focused ultrasound. However, the ability to recognise when image quality is insufficient for diagnosis is an important consideration for novice sonographers. Conclusions Focused cardiac and lung ultrasound examination by a junior doctor is feasible and may change preoperative diagnosis and management in patients of 65 years or older, admitted for emergency non-cardiac surgery.

Abstract
IMPORTANCE There are accumulating data about the utility of diagnostic multiorgan focused clinical ultrasonography (FCU) in the assessment of patients admitted with cardiopulmonary symptoms. OBJECTIVE To determine whether adding multiorgan FCU to the initial clinical evaluation of patients admitted with cardiopulmonary symptoms reduces hospital length of stay, hospital readmissions, and in-hospital costs. DESIGN, SETTING, AND PARTICIPANTS This is a prospective, parallel-group, superiority, randomized clinical trial with a 1:1 allocation ratio. The study was conducted at The Royal Melbourne Hospital, a tertiary public hospital located in Melbourne, Victoria, Australia. Adults aged 18 years or older admitted to the internal medicine ward with a cardiopulmonary diagnosis were enrolled between September 2018 and December 2019 and were followed up until hospital discharge. Data analysis was performed from August 2020 to January 2021. INTERVENTIONS The intervention involved an internal medicine physician-performed heart, lung, and 2-point vein compression FCU in addition to standard clinical evaluation. MAIN OUTCOMES AND MEASURES The primary outcome was the difference in the mean length of hospital stay, defined as the number of hours from admission to the internal medicine ward to hospital discharge. A difference of 24 hours was defined as clinically important. Secondary outcomes included hospital readmissions at 30 days and hospital care costs. RESULTS A total of 250 participants were enrolled and 2 were excluded, leaving 248 participants (mean [SD] age, 80.1 [11.0] years; 121 women [48.7%]) in the final analysis. There were 124 patients in the intervention group and 124 patients in the control group. The most common initial diagnoses were acute decompensated heart failure (113 patients [45.5%]), pneumonia (45 patients [18.1%]), and exacerbated chronic pulmonary disease (32 patients [12.9%]). The length of hospital stay was 113.4 hours (95% CI, 91.7-135.1 hours) in the FCU group and 125.3 hours (95% CI, 101.7-148.8 hours) in the control group (P = .53). The 30-day readmission rate was not different between groups (FCU vs control, 20 of 124 patients [16.1%] vs 15 of 124 patients [12.0%]), nor were total in-hospital costs (FCU vs control, A$7831.1 [95% CI, A$5586.1-A$10 076.1] vs A$7895.7 [95% CI, A$6385.9-A$9.405.5]). CONCLUSIONS AND RELEVANCE In this randomized clinical trial, adult patients admitted to an internal medicine ward with a cardiopulmonary diagnosis, who underwent multiorgan FCU of the heart, lungs, and lower extremities veins during their initial clinical assessment, did not have a shorter hospital length of stay by more than 24 hours, compared with patients who received standard care.

Abstract
BACKGROUND: Elevation of the left ventricular (LV) filling pressure can occur during weaning of mechanical ventilation due to increase in LV preload and/or changes in LV compliance and LV afterload.
AIM: The aim of the study was to evaluate respiratory changes in internal jugular vein and inferior vena cava during weaning from mechanical ventilation.
METHODS: Prospective observational study conducted on 80 consecutive patients. Patients were divided randomly into two groups who met the readiness criteria to start spontaneous breathing trial (SBT) either on pressure support ventilation (PS/CPAP) for 30 min or T-piece for 120 min. Weaning failure was defined as a failed SBT or reintubation within 48 h. Echocardiographic evaluation was done on assisted controlled ventilation and at the end of SBT for preload assessment.
RESULTS: Mitral Septal E/E’ Cutoff value ≥6.1 with sensitivity 81% and specificity 84.2%, and AUC 0.73 for predicting weaning failure. IVC distensibility index on CPAP cutoff value ≥66.5% with sensitivity 100% and specificity 68.4%, and AUC 0.85. In Group II, Mitral Septal E/E’ Cut off value ≥5.8 with sensitivity 83% and specificity 90.9%, AUC 0.83, IVC collapsibility index Cut off value ≥45.5% with sensitivity 72% and specificity 86%, AUC 0.73.
CONCLUSION: Mitral Septal E/E’ could predict weaning-induced diastolic dysfunction. IVC plays an important role in predicting weaning failure.

Abstract
There is a growing trend of using ultrasound examination of the heart as a first-line diagnostic tool for initial patient evaluation in acute settings. Focus cardiac ultrasound (FoCUS) is a standardized but restricted cardiac ultrasound examination that may be undertaken by a range of medical professionals with diverse backgrounds. The intention of this core curriculum and syllabus is to define a unifying framework for educational and training processes/programmes that should result in competence in FoCUS for various medical professionals dealing with diagnostics and treatment of cardiovascular emergencies. The European Association of Cardiovascular Imaging prepared this document in close cooperation with representatives of the European Society of Anaesthesiology, the European Association of Cardiothoracic Anaesthesiology, the Acute Cardiovascular Care Association of the European Society of Cardiology and the World Interactive Network Focused On Critical Ultrasound. It aims to provide the key principles and represents a guide for teaching and training of FoCUS. We offer this document to the emergency and critical care community as a reference outline for teaching materials and courses related to FoCUS, for promoting teamwork and encouraging the development of the field.

Abstract
Ultrasound is increasingly being adopted into anaesthesia and intensive care practice. The range of ultrasound examination has also increased from transoesophageal echocardiography in cardiac surgery and ultrasound-guided nerve blocks and vascular access, to examination of the heart, lungs, abdomen and deep veins. Typically, the use of ultrasound is focused or basic, designed to be performed by the anaesthetist at the patient's bedside in real time to answer clinical questions and to direct therapy. Ultrasound is not performed in isolation, but used to complement clinical evaluation, and accordingly can be considered as 'ultrasound-assisted perioperative evaluation'. Whilst there is good evidence that ultrasound improves diagnostic accuracy and in turn alters management, there are few data examining whether ultrasound leads to improved clinical outcomes. This review will examine multiple uses of perioperative ultrasound with case studies to illustrate potential utility.

Abstract
PURPOSE Focused cardiac ultrasound (FCU) training in critical care is restricted by availability of instructors. Supervised training may be substituted by self-directed learning with an ultrasound simulator guided by automated electronic learning, enabling scalability. MATERIALS AND METHODS We prospectively compared learning outcomes in novice critical care physicians after completion of a supervised one-and-a-half-day workshop model with a self-guided course utilizing a simulator over four weeks. Both groups had identical pre-workshop on-line learning (20h). Image quality scores were compared using FCU performed on humans without pathology. Interpretive knowledge was compared using 20MCQ tests. RESULTS Of 161 eligible, 145 participants consented. Total Image quality scores were higher in the Simulator group (95.2% vs. 66.0%, P < .001) and also higher for each view (all P < .001). Interpretive knowledge was not different before (78.6% vs. 79.0%) and after practical training (74.7% vs. 76.1%) and at 3 months (81.0% vs. 77.0%, all P > .1). Including purchase of the simulator and ultrasound equipment, the simulator course required lower direct costs (AUD$796 vs. $1724 per participant) and instructor time (0.5 vs.1.5 days) but similar participant time (2.8 vs. 3.0 days). CONCLUSIONS Self-directed learning with ultrasound simulators may be a scalable alternative to conventional supervised teaching with human models.

The impact of heart, lung and diaphragmatic ultrasound on prediction of failed extubation from mechanical ventilation in critically ill patients: a prospective observational pilot study. Crit Ultrasound J 2018; 10:13. [PMID: 29971618 PMCID: PMC6029991 DOI: 10.1186/s13089-018-0096-1] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2017] [Accepted: 05/03/2018] [Indexed: 12/19/2022] Open
Abstract
Background Failed extubation from mechanical ventilation in critically ill patients is multifactorial, complex and not well understood. We aimed to identify whether combined transthoracic echocardiography, lung and diaphragmatic ultrasound can predict extubation failure in critically ill patients. Results Fifty-three participants who were intubated > 48 h and deemed by the treating intensivist ready for extubation underwent a 60-min pre-extubation weaning trial (pressure support ≤ 10 cmH2O and positive end expiratory pressure 5 cmH2O). Prior to extubation, data collected included ultrasound assessment of left ventricular ejection fraction, left atrial area, early diastolic trans-mitral flow velocity wave (E), early diastolic trans-mitral flow velocity wave/late diastolic trans-mitral flow velocity wave (E/A), early diastolic trans-mitral flow velocity wave/early diastolic mitral annulus velocity (E/E′), interatrial septal motion, lung loss of aeration score and diaphragm movement. At the end of the weaning trial, the rapid shallow breathing index and serum B-type natriuretic peptide concentration were measured. Success and failure of weaning was assessed by defined criteria. Decision to extubate was at the discretion of the treating intensivist. Failure of extubation was defined as re-intubation, non-invasive ventilation or death within 48 h after extubation. Of 53 extubated participants, 11 failed extubation. Failed extubation was associated with diabetes, ischaemic heart disease, higher E/E′ (OR 1.27, 95% CI 1.05–1.54), left atrial area (OR 1.14, CI 1.02–1.28), fixed rightward curvature of the interatrial septum (OR 12.95, CI 2.73–61.41), and higher loss of aeration score of anterior and lateral regions of the lungs (OR 1.41, CI 1.01–1.82). Conclusions Failed extubation in mechanically ventilated patients is more prevalent if markers of left ventricular diastolic dysfunction and loss of lung aeration are present.

Abstract
Sepsis continues to be a leading cause of mortality and morbidity in the intensive care unit. Cardiovascular dysfunction in sepsis is associated with worse short- and long-term outcomes. Sepsis-related myocardial dysfunction is noted in 20%-65% of these patients and manifests as isolated or combined left or right ventricular systolic or diastolic dysfunction. Echocardiography is the most commonly used modality for the diagnosis of sepsis-related myocardial dysfunction. With the increasing use of ultrasonography in the intensive care unit, there is a renewed interest in sepsis-related myocardial dysfunction. This review summarises the current scope of literature focused on sepsis-related myocardial dysfunction and highlights the use of basic and advanced echocardiographic techniques for the diagnosis of sepsis-related myocardial dysfunction and the management of sepsis and septic shock.

Abstract
We investigated whether the interatrial septal (IAS) motion of each heartbeat which is observed by transesophageal echocardiography reflects left atrial pressure (LAP) in patients with atrial fibrillation (AF). We studied 100 patients (70 males, age 67 ± 9 years) who underwent catheter ablation for AF. The amplitude of IAS motion was measured using M-mode and averaged for five cardiac cycles. Left and right atrial pressures, the left to right atrial pressure gradient were directly measured during the catheter ablation. In patients with sinus rhythm during measurement, elevated mean LAP, larger maximum left to right atrial pressure gradient, and greater left atrial emptying fraction were associated with IAS motion. The optimal cut-off value of the IAS motion for predicting high LAP (mean LAP > 15 mmHg) was 8.5 mm (sensitivity 100%, specificity 70.1%) in patients with sinus rhythm during pressure measurement. In addition, all patients were divided into 6 groups based on rhythm during measurement and cutoff value of IAS motion. In patients with sinus rhythm during measurement, low IAS motion group had a highest prevalence of elevated LAP compared with high IAS motion group (64 vs. 0%, P < 0.0001). The amplitude of interatrial septal motion during sinus rhythm reflects left atrial pressure in patients with atrial fibrillation. Interatrial septal motion could be a new index to predict elevated left atrial pressure.

Abstract
PURPOSE OF REVIEW A need for further assessment of patients in the perioperative setting and an increasing availability of ultrasonography equipment have facilitated the diffusion of ultrasonography and lately focused transthoracic echocardiography (TTE) in anesthesiology practice. This review will discuss the possible use of focused TTE in the perioperative setting and provides an update on present and future perspectives. RECENT FINDINGS Several studies focusing on patient management and diagnostic accuracy of perioperative, focused TTE, have been published recently. Several multidisciplinary guidelines addressing use and educational aspects of focused ultrasonography are available, yet guidelines focusing solely on the use in the perioperative setting are lacking. SUMMARY Hemodynamically significant cardiac disease or pathophysiology can be disclosed using TTE. Focused TTE is feasible for perioperative patient management and monitoring and will be an inevitable and indispensable tool for the anesthetist. Future research should focus on the outcome of perioperative TTE performed by anesthetists, using rigorous study designs and patient-centered outcomes such as mortality and morbidity.

Abstract
BACKGROUND Ultrasound-assisted examination of the cardiovascular system with focused cardiac ultrasound by the treating physician is non-invasive and changes diagnosis and management of patient's with suspected cardiac disease. This has not been reported in a general practice setting. AIM To determine whether focused cardiac ultrasound performed on patients aged over 50 years changes the diagnosis and management of cardiac disease by a general practitioner. DESIGN AND SETTING A prospective observational study of 80 patients aged over 50years and who had not received echocardiography or chest CT within 12months presenting to a general practice. METHOD Clinical assessment and management of significant cardiac disorders in patients presenting to general practitioners were recorded before and after focused cardiac ultrasound. Echocardiography was performed by a medical student with sufficient training, which was verified by an expert. Differences in diagnosis and management between conventional and ultrasound-assisted assessment were recorded. RESULTS AND CONCLUSION Echocardiography and interpretation were acceptable in all patients. Significant cardiac disease was detected in 16 (20%) patients, including aortic stenosis in 9 (11%) and cardiac failure in 7 (9%), which were missed by clinical examination in 10 (62.5%) of these patients. Changes in management occurred in 12 patients (15% overall and 75% of those found to have significant cardiac disease) including referral for diagnostic echocardiography in 8 (10%), commencement of heart failure treatment in 3 (4%) and referral to a cardiologist in 1 patient (1%).Routine focused cardiac ultrasound is feasible and frequently alters the diagnosis and management of cardiac disease in patients aged over 50years presenting to a general practice.

Abstract
BACKGROUND The pulmonary artery catheter (PAC) has historically been used to measure cardiac filling pressures of which pulmonary capillary wedge pressure (PCWP) has been used as a surrogate of left atrial pressure (LAP) and left ventricular end-diastolic pressure. Increasingly, the use of the PAC has been questioned in the perioperative period with multiple large studies unable to clearly demonstrate benefit in any group of patients, resulting in a declining use in the perioperative period. Alternative methods for the noninvasive estimation of left-sided filling pressures are required. Echocardiography has been used to provide noninvasive estimation of PCWP and LAP, based on evaluating mitral inflow velocity with the E and A waves and looking at movement of the mitral annulus with tissue Doppler (e'). AIM The aim of our study was to assess the relationship between PCWP and E/e' in cardiac surgical patients with transesophageal echocardiography (TOE). DESIGN A prospective observational study. SETTING Cardiac surgical patients in a single quaternary referral university teaching hospital. METHODS The ratio of mitral inflow velocity (E wave) to mitral annular tissue velocity (e') (the E/e' ratio) and PCWP of 91 patients undergoing general anesthesia and cardiac surgery were simultaneously recorded, with the use of TOE and a PAC. RESULTS The correlation between E/e' and PCWP was modest with a Spearman rank correlation coefficient of 0.29 (P = 0.005). The area under the receiver operating characteristic curve for using E/e' to predict elevated PCWP (≥18 mmHg) was 0.6825 (95% confidence interval: 0.57-0.80), indicating some predictive utility. The optimum threshold value of E/e' was 10 which had 71% sensitivity and 60% specificity to predict a PCWP ≥18 mmHg. CONCLUSIONS Noninvasive measurements of E/e' in general cardiac surgical patients have only a modest correlation and does not reliably estimate PCWP.
