Description: A brief explaination of spinal anaesthesia by injecting a local anaesthetic into the spinal canal. Pantocaine and products composed of pantocaine are used. Two techniques are shown the first representing the use of solutions heavier than cerebrospinal fluid the second representing the use of solutions lighter than cerebrospinal fluids. Their practical application to the patient is shown using diagrams and then using nupercaine and the anaesthetic agent on patients. A lumbar puncture is demonstrated using the sitting position on a female patient. Advice is given explaining how to do this if the patient has either scoliosis or lordosis. Hygiene is very important. 'Barbotage' is demonstrated on a glass tube representing the spinal canal. Ends suddenly.
