This is a demonstration of the steps of performing a Lumbar Puncture on a Gaumard Scientific Trainer. We have been using this trainer for quite some time and it has given us good service. The commentator is Dr Sanjoy Sanyal, Professor and Course Director of Neuroscience and FCM-III Neurology in the Caribbean. It describes the LP procedure from locating the L4 landmark, to positioning the simulated 'patient', to Skin Prepping, to Sterile Draping to Local Anesthesia infiltration, followed by the steps of the actual LP procedure and its conclusion. ACKNOWLEDGMENTS: Special thanks are being extended to Gaumard Scientific and its Vice President, John Eggert, for giving us explicit written permission to use the pictures of Gaumard Scientific in this demonstration. Camera person for this video is Mr. Mark Lessard, IT Administrator par excellence, with his high definition Sony HDR XR520 video camera.
