Our brain and spinal cord are surrounded by fluid called cerebrospinal fluid. Lumbar puncture is a procedure in which doctor collects a sample of cerebrospinal fluid which can be tested in the lab for diseases of the brain and spinal cord.
Please inform your doctor if you are on blood thinners or history of bleeding tendencies.
You are settled comfortably in an area where your privacy is respected throughout the procedure. You will be given a hospital gown to change into.
Doctor will ask you to lie on your side and fold your legs, so that your back is curved in a C shape.
Then doctor will disinfect your back with an antiseptic solution and numb it with local anaesthesia which is injected into the lower back area.
A hollow needle is inserted into your lower spinal cord to collect a small sample of cerebrospinal fluid.
