Brief Summary

Background: Popliteal block is a widely used technique to provide anesthesia or analgesia for below-knee surgical procedures. In this study, the investigators compare ultrasound-guided popliteal blocks via posterior, lateral, and medial approaches to find out the approach with the best outcome.

Conditions

Nerve Pain

Outcome Measures

Primary Outcomes (1)

• assessment of intraoperative and postoperative pain in different groups after intervention

  pain severity levels via visual analogue scale (VAS). VAS is a 10 cm horizontal line labeled "no pain" at one end and "worst pain" imaginable on the other end. The patient was asked to mark on this line where the intensity of the patient lies

  24 hours after operation

Study Arms (3)

popliteal block posterior approach group

ACTIVE COMPARATOR

through posterior approach ultrasound guided sciatic nerve block at popliteal fossa 20ml of the selected local anesthetic mixture (10ml of 0.5% bupivacaine mixed with 10ml of 2% lidocaine, each with 1:200,000 epinephrine) was injected incrementally

Procedure: popliteal block

popliteal block lateral approach group

ACTIVE COMPARATOR

ultrasound guided sciatic nerve block at popliteal fossa through lateral approach 20ml of the selected local anesthetic mixture (10ml of 0.5% bupivacaine mixed with 10ml of 2% lidocaine, each with 1:200,000 epinephrine) was injected incrementally

Procedure: popliteal block

poplitea block medial approach group

ACTIVE COMPARATOR

ultrasound guided sciatic nerve block at popliteal fossa through medial approach 20ml of the selected local anesthetic mixture (10ml of 0.5% bupivacaine mixed with 10ml of 2% lidocaine, each with 1:200,000 epinephrine) was injected incrementally

Procedure: popliteal block

Interventions

popliteal block PROCEDURE

using ultrasound to detect sciatic nerve and popliteal fossa through different approaches using 20ml of the selected local anesthetic mixture (10ml of 0.5% bupivacaine mixed with 10ml of 2% lidocaine, each with 1:200,000 epinephrine) was injected incrementally

poplitea block medial approach group; popliteal block lateral approach group; popliteal block posterior approach group
