3rd Rock Ultrasound – Module 1Slide 2
The indications & techniques presented in this cousre have been recommended in the medical literature and/or conform to the clincial practice of OUR faculty.
The equipment has not necessarily been approved by the Food and Drug Administration (FDA) for use in the techniques for which they are recommended. The package insert for the equipment should be consulted for use as recommended by the FDA.
Because standards, practices and recommendations change, it is advisable to keep abreast of revised recommendations, particularly those concerning new drugs and techniques. While the techniques described are successfully used in our practice, they should be followed with discretion since their complications may be dependent on the operator, patient and/or other accompanying clinical circumstances.
The equipment discussed in this course is shown solely for teaching purposes. Similar equipment from other manufacturers may produce similar clinical results to ours.

COMPARISON OF EFFECTIVENESS OF HAND-CARRIED ULTRASOUND TO BEDSIDE CARDIOVASCULAR PHYSICAL EXAMINATIONKobal, S.L., et al, Am J Card 96(7):1002, October 1, 2005
METHODS: The authors, from Cedars-Sinai Medical Center and UCLA, compared the diagnostic accuracy of physical examination performed by one of five board-certified cardiologists, and use of a hand-carried ultrasound (HCU) device (OptiGo, Philips) by one of two first-year medical students in 61 patients with clinically significant cardiac disease. The students received 18 hours of training in use of the HCU device, which provides two-dimensional and conventional color- flow Doppler imaging, including four hours of lectures and 14 hours of practical experience. Expert echocardiography was the diagnostic gold standard.
RESULTS: Standard echocardiography identified 239 abnormalities in these patients (average, 3.9 per patient). Using the HCU, the students recognized 75% of these abnormalities compared with 49% identified by the cardiologists on physical examination (p<0.001). Corresponding specificities were 87% vs. 76% (p<0.001). The students were significantly more accurate than the cardiologists in the recognition of the most severe cases of left ventricular (LV) dysfunction and severe valvular disease (96% vs. 68%, p<0.001), and HCU exams by the students were also more accurate than physical exams by the cardiologists in the recognition of lesions that cause systolic or diastolic murmurs.
CONCLUSIONS: These findings reflect the inherent difficulties in evaluation of organ systems through percussion, palpation and auscultation, and the utility of technology developed to facilitate patient assessment at the bedside.

1) Appropriate use of prophylaxis to prevent venous thromboembolism in patients at risk;2) Use of perioperative beta-blockers in appropriate patients to prevent perioperative
morbidity and mortality;3) Use of maximum sterile barriers while placing central intravenous catheters to prevent
infections;4) Appropriate use of antibiotic prophylaxis in surgical patients to prevent postoperative
infections;5) Asking that patients recall and restate what they have been told during the informed
consent process;6) Continuous aspiration of subglottic secretions (CASS) to prevent ventilator-associated
pneumonia;7) Use of pressure relieving bedding materials to prevent pressure ulcers;8) Use of real-time ultrasound guidance during central line insertion to prevent
complications;9) Patient self-management for warfarin (Coumadin™) to achieve appropriate outpatient
anticoagulation and prevent complications;10) Appropriate provision of nutrition, with a particular emphasis on early enteral nutrition
in critically ill and surgical patients; and11) Use of antibiotic-impregnated central venous catheters to prevent catheter-related
infections.
