Illustration depicting lumbar puncture (spinal tap) Spinal needles used in lumbar puncture Illustration depicting common positions for lumbar puncture procedure. The person is usually placed on their side (left more commonly than right). The patient bends the neck so the chin is close to the chest, hunches the back, and brings knees toward the ...
For those children with spinal cord diseases, lumbar puncture may damage the spinal cord due to possibility of tethered spinal cord syndrome where the spinal cord is located below than the usual spinal termination level. [3] Therefore, lumbar puncture should be done at the lowest position as possible for such cases. However, spinal cord injury ...
Ultrasound-guided lumbar puncture is a medical procedure used in some emergency departments to obtain cerebrospinal fluid for diagnostic purposes. In contrast to standard lumbar puncture by palpation , the use of ultrasound imaging may reduce the number of failed punctures, needle insertions, and needle redirections. [ 1 ]
Spinal anaesthesia (or spinal anesthesia), also called spinal block, subarachnoid block, intradural block and intrathecal block, [1] is a form of neuraxial regional anaesthesia involving the injection of a local anaesthetic or opioid into the subarachnoid space, generally through a fine needle, usually 9 cm (3.5 in) long.
An epidural blood patch (EBP) is a surgical procedure that uses autologous blood, meaning the patient's own blood, in order to close one or many holes in the dura mater of the spinal cord, which occurred as a complication of a lumbar puncture or epidural placement. [1] [2] The punctured dura causes cerebrospinal fluid leak (CSF leak). [1]
Bone marrow aspiration may also be performed on the tibial (shinbone) site in children up to 2 years of age while spinous process aspiration is frequently done in a lumbar puncture position and on the L3-L4 vertebrae. [citation needed] Anesthesia is used to reduce surface pain at the spot where the needle is inserted.
The kidney position is much like the lateral position except the patient's abdomen is placed over a lift in the operating table that bends the body to allow access to the retroperitoneal space. A kidney rest is placed under the patient at the location of the lift. [2] Sims' position The Sims' position is a variation of the left lateral position.
Given normal anatomy, the intracranial pressure will be reflected as a rapidly rising pressure measured from the lumbar needle, within 10–12 seconds. If there is a stenosis in the spine, there will be a damped, delayed response in the lumbar pressure, thus a positive Queckenstedt's maneuver.
