INTRO

•Peripheral nerve stimulation (PNS) has evolved from permanently implanted systems to minimally invasive, temporary leads placed under ultrasound guidance.

•It offers a promising alternative for focal pain conditions, including perioperative pain.

•

METHODS

•A retrospective analysis of 185 patients treated with PNS at Penn State Hershey Medical Center (2021–2024) was conducted.

•105 Peri-operative and 80 chronic pain patients.

•Outcomes were assessed using NRS scores, PGIC metrics, and medication usage patterns over treatment durations ranging from 1 to 107 days.

RESULTS

Peri-operative PNS placement reduced 60 day post-op pain by 16.8% (p<0.001).

DISCUSSION

•Early intervention in perioperative settings may prevent acute pain from progressing to chronic pain.

•Future research should refine patient selection criteria and explore long-term outcomes.

•Future studies should target a possible higher success rate with 2 nerve intervention when possible.
