OBJECTIVE: The aim of this study is to compare the effects of parasacral and posterior Winnie approaches when combined with the inguinal paravascular approach for lumbar plexus block.
METHODS: After the approval of the Ethics Committee, 40 patients scheduled to undergo arthroscopic knee surgery were enrolled. The patients were randomly assigned into two groups in a double-blind manner to perform sciatic nerve block either by the parasacral technique (Group I) or by the posterior approach (Group II).
RESULTS: The obturator nerve motor block success rate was found to be 80% (16/20) in Group I, whereas it was 10% (2/20) in Group II (p<0.05).
CONCLUSION: Inguinal paravascular block with parasacral sciatic nerve block led to a much higher incidence of obturator nerve motor block when compared to the inguinal paravascular block with posterior sciatic nerve block during knee arthroscopies.

Keywords: Nerve block, arthroscopy, obturator and sciatic nerve
