ABSTRACT:
A nerve block needle is curved in a manner for use in penetrating skin and muscle at the side of a rib, so as to have the tip re-entrant, in the direction of and proximate to the groove in the inner surface of the rib, the said groove carrying the intercostal vein artery and nerve. A conventional local anesthetic drug can then be introduced in close proximity to the intercostal nerve with enhanced safety with respect to puncturing and collapse of the underlying lung. Such complication, known as pneumothorax, may occur with the use of a conventional straight nerve block needle. Other advantages of the curved needle and method of use will be subsequently explained.
