Sciatic Technique Comparison of Nerve Blockade for Pain Control Following Hamstring Autograft Harvest in Adolescents

Single-injection sciatic PNB is a regional anesthetic technique employed to anesthetize the sciatic nerve with a single dose of local anesthetic. This technique offers pain control for a limited amount of time based on the volume and concentration of local anesthetic used.

"Continuous sciatic PNB entails placing a continuous perineural infusion (CPI) catheter so that local anesthetic may be released slowly but continuously adjacent to the sciatic nerve (perineural) for several days postoperatively. The continuous PNB has the ability to reliably provide analgesia on subsequent postoperative days.~Participants my be randomized to receive an additional experimental continuous pain ball during surgery which can provide up to 48 hours of pain relief."
