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.
A shallow wheal of local anesthetic is set in the stage of needle entrance. A 6 tsp mix of 5ml of bupivacaine 0.5percent and 1ml of 40 mg/ml of triamcinolone is put in a 10cc syringe. A 20-gauge 3.5 inch regular cutting back spinal needle is directed in-plane under real time ultrasound [4] guidance into the anterior capsular recess. After the ...

However, the standard length of a spinal needle (90mm) may be insufficiently long to reach the subarachnoid space through the Tuohy needle. An extra-long needle (e.g., 120 mm) may be required. Alternatively, several manufacturers produce packs containing both a spinal and an epidural needle which are slightly modified to fit together.
A spinal needle is inserted between the lumbar vertebrae L3/L4, L4/L5 [10] or L5/S1 [10] and pushed in until there is a "give" as it enters the lumbar cistern wherein the ligamentum flavum is housed. The needle is again pushed until there is a second 'give' that indicates the needle is now past the dura mater.
Size steps between gauges range from 0.001 inches (0.025 mm) between high gauge numbers to 0.046 inches (1.2 mm) between the two lowest gauge numbers and do not correspond to a particular mathematical pattern, although for the most part the steps get smaller with increasing gauge number. [3]
While the standard needle size for vaccination is 1 inch, it's recommended that women over 200 lbs. and men over 260 lbs. get shots with 1.5-inch needles. (Getty Images) (Nicolae Toma / 500px via ...
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
