Davis, T. Lumbar Punctures, Don't Forget the Bubbles, 2014. Available at:
This week’s Vodcast of the Week is Brad Sobolewski’s fantastic teaching on lumbar puncture in children.
He covers indications, anatomy, and complications of LP; and the video includes a demonstration of positioning and optimising your technique.
This is without a doubt the best and most comprehensive teaching I have seen on this procedure. You can watch the video below, and see more info in the full PEMBlog post.
