Safe guide is a central venous catheterization kit that serves as both pilot needle and introducer. With a single puncture, a guide wire can be introduced by inserting it through the side port of the 22-gauge needle. The advantage is that this needle can be placed within a blood vessel using no more force than is required to insert a pilot needle. ⋯ The use of our modified guide wire decreased the incidence of kinking and locking of the guide wire when passing it through the side port. In addition, no guide wire kinking at the puncture site occurred when introducing the dilator. Issues associated with the original J-type guide wire were resolved by 1) changing the guide wire tip to a gentler angle, and 2) fortifying the guide wire by altering its composition.
