CARDIAC ABDOMINAL AORTA VASCULAR LUNG OPTIC NERVE OB/GYN SOFT TISSUE BONE & DVT PROCEDURES PROTOCOLS Preface The ICU Ultrasound pocket book is far and above the most concise, targeted reference source to enable the novice or advanced emergency or ICU clinician to incorporate point of care ultrasound into their practice This book effectively teams internationally recognized sonologists with NASA researchers developing just in time ultrasound training methods for astronauts on the International Space Station, to provide a rapid ultrasound diagnostic and procedural guide for the ICU The comprehensive sections included in this book cover the ever expanding array of clinical indications for non-radiologist performed ultrasound and provide a novel addition to this field Scott A Dulchavsky MD PhD Detroit 2010 Foreword Bedside intensivist-performed ultrasonography easily qualifies as one of the most, if not the most important paradigm shifting technology developed in critical care in recent years The availability of less expensive, smaller machines with better resolution has made bedside examination by the intensivist feasible What is it about bedside ultrasonography that is so compelling for the ICU physician? Ultrasonography permits the “ultimate” physical examination It allows immediate assessment of vital cardiopulmonary, abdominal, renal, and vascular structural and functional elements in the unstable patient Considerably less diagnostic guess work results in a more precise workup, with less unnecessary, and potentially hazardous, transports to radiology Furthermore it replaces “blind” or landmark guided procedures with defined anatomic visualization that translates into safer, faster, and less painful procedures Critical Care physicians have been slower than their Emergency Medicine colleagues to adopt this technology, but this is changing rapidly There is an expanding literature on the use of ultrasonography in critically ill patients Recent consensus guidelines outlining specific elements of knowledge that define competency in critical care ultrasound have been published Training guidelines and examinations designed to demonstrate proficiency in critical care ultrasonography are the next steps to fully establishing intensivist-performed ultrasound This book succeeds outstandingly in one important part of that process: the creation of educational materials designed to be used at the ICU bedside to guide image acquisition, image interpretation, and procedural ultrasound As such “The ICU Ultrasound Pocket Book” is a valuable resource for medical students, nurses, physician extenders, residents, and fellows, as well as practicing intensivists PREFACE FOREWORD John M Oropello, MD, FCCM, FCCP, FACP Program Director, Critical Care Medicine Professor of Surgery & Medicine Mount Sinai School of Medicine New York, N.Y GETTING STARTED CARDIAC ABDOMINAL AORTA VASCULAR LUNG OPTIC NERVE OB/GYN SOFT TISSUE BONE & DVT PROCEDURES PROTOCOLS PREFACE FOREWORD GETTING STARTED CARDIAC ABDOMINAL AORTA VASCULAR LUNG OPTIC NERVE OB/GYN SOFT TISSUE BONE & DVT PROCEDURES PROTOCOLS Getting Started Equipment, Knobology & Terminology Ashot Sargsyan, MD Kathleen Garcia, FASE, RVT Advantages of Ultrasound Contents Transducers 11 Ultrasound Machine 12 Definitions 13 Modes 14 Controls 16 Image Orientation 18 Terminology 20 Transducer Orientation 21 Getting Started 22 • Noninvasive • Highly feasible • Rapid, versatile & repeatable • Time saving Be familiar with your ultrasound machine Knobology may be presented differently by different machines, but the principle is the same Setting the machine initially to obtain the best sonographic picture is of ultimate importance The learning curve is usually steep 10 PREFACE FOREWORD GETTING STARTED CARDIAC ABDOMINAL AORTA VASCULAR LUNG OPTIC NERVE OB/GYN SOFT TISSUE BONE & DVT PROCEDURES PROTOCOLS Tracheostomy & Endotracheal ( ET) Intubation Tracheal Ring Procedure and Views Tracheostomy Procedure to be performed following the standard technique Thyroid Gland Pre procedure ultrasound will help • Identify tracheal and paratracheal tissue and blood vessels • Identify the depth of the trachea • Choose best incision site US can be used during the procedure for guidance Trachea Carotid Artery ET intubation US can be used post intubation to confirm the ET tube inside the trachea Trachea/Short Axis 232 Tracheostomy & Endotracheal ( ET) Intubation Procedure and Views (cont.)
