💉 Ultrasound-Guided Supraclavicular Brachial Plexus Block
"The Spinal of the Arm" — Simplified in 6 High-Yield Illustrated Slides! 📚
The supraclavicular approach to the brachial plexus is often referred to as the "Spinal of the Arm" because the brachial plexus is tightly packed at the level of the trunks and divisions, allowing for rapid onset and dense anesthesia of the upper limb distal to the shoulder.
✅ Key Learning Points
✅ Rapid onset with dense sensory and motor block
✅ Excellent choice for elbow, forearm, wrist, and hand surgeries
✅ Ultrasound guidance improves accuracy and safety
✅ First rib acts as an important safety landmark, protecting the pleura
✅ The intercostobrachial nerve (T2) is usually not blocked
⚠️ Always visualize the needle tip and pleura throughout the procedure to minimize complications.
