To Stick or Not to Stick: A Primer on Ultrasound Guided Procedural Safety-Slides

Slides

Pdf Summary

This presentation by Dr. Manpreet S. Malik, Associate Professor of Medicine at Emory University, focuses on ultrasound-guided procedural safety in various bedside interventions. It covers ultrasound safety principles, technical tips, medication considerations, and detailed guidance on central line placement, thoracentesis, paracentesis, and lumbar puncture.<br /><br />Key points include the demonstrated benefits of ultrasound for central venous catheterization, such as reduced mechanical complications (pneumothorax, hemothorax, arterial puncture), lower infection rates, improved success rates, and faster cannulation times compared to landmark techniques. Pre-procedure ultrasound evaluation of the internal jugular vein (IJ), including its relationship to the carotid artery, size, depth, and ruling out thrombosis, enhances safety and procedural success. Technical tips emphasize proper ergonomics, needle visualization, guidewire control, securement, and post-procedure confirmation, including pleural sliding to rule out pneumothorax.<br /><br />For paracentesis, ultrasound improves detection of peritoneal free fluid, increases success rates (95% vs. 61%), and decreases bleeding complications. The presentation stresses careful site selection by identifying the largest and shallowest fluid collections, avoiding vessels and adjacent structures using Doppler ultrasound, and aspirating as the needle advances.<br /><br />Similarly, ultrasound-guided thoracentesis allows superior detection of pleural effusions, accurate site marking, and reduced risk of injury to adjacent organs. Volume, character, site selection with avoidance of intercostal vessels, and lung sliding are emphasized.<br /><br />Lumbar puncture benefits from ultrasound guidance, notably in obese patients, with reduced failed procedures, needle redirections, traumatic taps, and attempts. Detailed sono-anatomy and probe techniques support real-time guidance for safer access.<br /><br />The presentation concludes with discussion of anticoagulation considerations, encourages audience questions, and provides instructions for CME credit evaluation. Overall, the use of point-of-care ultrasound significantly enhances procedural safety and efficacy in common bedside interventions.
