Brief Summary

In the present study, the investigators will test the effect of two position on posterior lumbar plexus and subgluteal or sub-greater trochanter sciatic nerve block.

Conditions

Lower Limb Surgery

Keywords

Lumbar plexus block; sciatic nerve block; position; ultrasound guidance; elective lower limb surgery

Outcome Measures

Primary Outcomes (2)

• Block success defined as loss of sensation to pinprick in each of the lumbar plexus and sciatic nerve distributions when measured 30 min after block performance.

  30min

• Motor blockade was evaluated by assessing the strength of knee extension (femoral nerve), thigh adduction (obturator nerve), and plantar flexion and dorsiflexion of the ankle (sciatic nerve) 30 min after block performance.

  30min

Secondary Outcomes (1)

• block execution time, depth of the nerve, needle depth, duration of the sensory and motor blockade, complications such as inadvertent needle puncture of epidural space, dural puncture, peritoneal puncture, and kidney or ureter puncture and nerve injury.
