A Study Comparing Continuous Sciatic Nerve Block to Single Shot Sciatic Nerve Block

A Randomized Controlled Trial Comparing Continuous Sciatic Nerve Block to Single Shot Sciatic Nerve Block

The purpose of this study is to compare the incidence of postoperative symptoms of neurologic injury after a single shot infragluteal-parabiceps sciatic nerve block versus a continuous infragluteal-parabiceps sciatic nerve catheter.

There are a limited number of prospective studies in the literature examining the risk of neurologic injury and symptoms after sciatic nerve blocks. The incidence of transient neurological symptoms after a continuous catheter is not well reported.

Inclusion Criteria:

• all patients ( ≥18 and ≤ 80) who are scheduled to undergo elective scheduled foot surgery and agreed to receive a sciatic nerve catheter as a part of their postoperative pain management. this study.

Exclusion Criteria:

• history of hemostatic abnormalities
• chronic pain syndrome
• a foot deformity restricting normal foot movement
• severe liver or renal disease
• a preexisting neurologic disorder
• patient refusal to participate
• the presence of language barrier that prohibits proper communication with patient.
