Jailyn and Ben kick off a new podcast format where they discuss the full-length lectures published on the Core Ultrasound YouTube channel — adding commentary, clinical pearls, and behind-the-scenes discussion that doesn't make it into the edited videos. Why this new podcast format? The YouTube videos are kept concise, but a lot of valuable clinical discussion gets left on the cutting room floor. This podcast fills that gap. In this episode, they break down their approaches to ultrasound-guided thoracentesis, with a detour into related tips for paracentesis. Static vs. Dynamic approach Static: Identify the pocket, mark the spot, proceed with a landmark technique Dynamic: Watch the needle in real-time as it enters the fluid When to use each: Large effusions → static often sufficient; small or complex effusions → dynamic preferred Identifying the right pocket Find the largest fluid pocket that is cephalad enough to clear the diaphragm and caudal enough to avoid pneumothorax Watch diaphragm excursion with respiration to confirm safe needle trajectory Avoid inadvertent liver/spleen biopsy Probe and needle technique for thoracentesis Use a phased array or curvilinear probe to find the effusion, then switch to linear for the procedure Orient transducer in the intercostal space (sagittal, rotated) In-plane (long axis) approach recommended — short axis is mechanically difficult due to the ribs Probe orientation: oblique when lateral, nearly horizontal when posterior Paracentesis pearls Out-of-plane technique can work well, given the larger pockets typical in the ED Curvilinear probe makes needle identification harder vs. linear For small-volume paras (e.g., ruling out SBP), dynamic approach is strongly preferred Color Doppler before you needle Scan the intended trajectory with color Doppler to rule out intercostal arteries or abdominal wall vessels (e.g., inferior epigastrics, caput medusa) Release probe pressure nearly completely when looking for veins — they collapse easily and can be missed Resources Mentioned 🎥 Full lecture video: Core Ultrasound YouTube Channel 📚 Premium courses: courses.coreultrasound.com Thanks for listening — and happy scanning!
