Techniques like paresthesia, electrical nerve stimulation and ultrasound guidance have been introduced to improve needle placement.
The elicitation of paresthesia has shown a sensitivity of only 40 % for nerve detection while for nerve stimulation up to 75 % sensitivity has been reported .
The technique may therefore improve accurate needle placement near the nerve which is necessary for effective nerve blocks in regional anesthesia.] as well as a lower risk for delirium and nausea have been reported.
By incorporating optical fibers into needles, a method has been developed that can provide real-time tissue feedback at the tip of the needle.
However, the stimulation threshold does not give an exact indication of the distance between the needle and nerve.
