A syringe is connected to the epidural needle and the epidural space is identified by a technique to assess loss of resistance. Epidural administration is a procedure which requires the person performing the insertion to be technically proficient in order to avoid complications. Proficiency may be trained using bananas or other fruits as a model.
To provide continuous epidural analgesia or anesthesia, a small hollow catheter may be threaded through the epidural needle into the epidural space, and left there while the needle is removed. There are multiple types of epidural needles as well as catheters, but in modern practice in developed nations, disposable materials are used to ensure ...
Combined spinal-epidural anaesthesia is a highly specialised technique which should only be administered by a properly trained anaesthetic practitioner working with full aseptic technique. [citation needed] The needle-through-needle technique involves the introduction of a Tuohy needle (epidural needle) into the epidural space. The standard ...

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.
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.

It is a method for the identification of the epidural space, a potential space. As a needle is advanced through the ligamentum flavum, to the epidural space, with constant pressure applied to the piston of a syringe, loss of resistance occurs once the needle enters the epidural space due to the change in pressure.
