🔍 Ultrasound-Guided Lumbar Puncture – an essential POCUS technique for improving procedural success in CSF sampling, especially in ↑BMI or anatomically challenging patients with spinal deformities or prior surgeries, minimizing traumatic taps, needle redirects, and complications to enhance diagnostic accuracy and patient safety in emergency, neurology, and critical care environments. Best annotated and explained video I’ve seen 🤩 ⚡ Employ pre-procedural static marking to locate optimal L3-L4/L4-L5 interspace, boosting first-pass success rates to over 90% in difficult cases and reducing overall attempts. 🩺 📏 paramedian sagittal views for hyperechoic spinous processes (crescent-shaped with shadowing) and transverse views for midline identification, ensuring precise needle trajectory and depth estimation. 📐 🚨 Switch to curvilinear probes in obese patients for better penetration; this halves failure rates compared to landmark-based methods, particularly when BMI exceeds 30. 📈 🔍 Incorporate real-time guidance to avoid bone contacts and minimize traumatic LPs (e.g., RBC counts <400/mm³), with meta-analyses showing fewer complications like post-dural puncture headaches. ⚠️ 🤝 Integrate ultrasound with clinical assessment (e.g., palpation, patient positioning in sitting/lateral recumbent) for holistic management, supported by randomized trials in adult and pediatric populations across ED and ICU settings. 👥

GLP-1 RAs slow gastric emptying and may increase aspiration risk No studies have assessed the efficacy of pre-op erythromycin as a prokinetic. This case reports evaluates erythromycin efficacy with gastric ultrasound! #AnSky @drnavsidhu buff.ly/e4OZ9dE

Did you know your choice of ultrasound gel directly impacts image quality? High viscosity gels = superior air gap reduction & sharper resolution for details diagnostics Low viscosity gels= easy application but may dry out during longer scans Surprising fact? Homemade alternatives like cassava flour slurry can offer comparable image clarity to commercial gels.

Kudos to @colinrbell for leading this @CAEP_EUC effort to survey Canadian 🇨🇦 #POCUS programs •76% of POCUS equipment is used beyond service life •1/3 of programs receive $ for clinical POCUS use •1/2 don't have POCUS QA @CAEP_Docs @CJEMonline 🔗doi.org/10.1007/s43678…
