Anesthesiologist uses sciatic block in leg and foot surgeries. Labat sciatic block uses a series of anatomical landmarks, while parasacral uses simple anatomical landmarks. This study compared the success rate of parasacral approach of sciatic block to Labat approach using nerve stimulator in leg and foot surgeries. A double-blind randomized controlled trial study was conducted on 32 adult patients at Dr. Hasan Sadikin General Hospital Bandung and Dr. Slamet General Hospital Garut during the period of December 2014 to January 2015. In Labat group, a line was drawn from greater trochanter to posterior superior iliac spine. Then, from the midpoint of this line, a second line was drawn perpendicularly and extended caudally to 4 cm. The end of this line represented the needle entry. In parasacral group, a line was drawn from posterior superior iliac spine to ischial tuberosity. The needle entry was then marked on this line at 6 cm from the posterior superior iliac spine. Thirty mL of 0.4% bupivacaine was injected when a proper motor response was elicited at 0.3 mA. Comparison of success rates were analyzed using Fisher’s exact Test with p-value<0.05 considered significant. Fifteen blocks in parasacral group were successful compared to 8 blocks in Labat group, with p-value of 0.015. The success rate of parasacral approach of sciatic block is higher than in the Labat approach when using nerve stimulator in leg and foot surgeries.
