FIELD: medicine.
SUBSTANCE: invention refers to medicine, namely to anaesthesiology, and may be used in epidural anaesthesia. What is presented is an apparatus comprising a guide cylinder with a digital scale, with the mark pitch for an epidural needle. The guide cylinder is fixed on the periphery of a support plate window rotating in a perpendicular plane at an angle up to 160°. The window is placed in a projection of the interspinous space selected for puncture. The cylinder is specified to have the length of 0.44-0.45 equal to the effective length of the epidural needle, and an internal diameter greater than an outer diameter of the needle not more than in 1.42 times.
EFFECT: provided direct needle penetration into the epidural space by preventing lateral needle deviation when passing through patient's spinal soft tissues and ligaments with puncture of the epidural space from the median approach.
