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.

Detailed description

Methods: In this randomized, controlled clinical trial, one hundred and twenty ASA physical status of class I and II patients undergoing below-knee surgery were involved. These patients were divided into three equal groups at randomly based on the route assigned for the US-guided popliteal block: the posterior, lateral, and medial approach groups. In this study, technical characteristics \[number of attempts to get the proper injection site and block performance time\], anesthetic and analgesic characteristics \[success rate, block onset, potency, and duration, time to ask, and the consumed amount of postoperative analgesia\], discomfort rate in respect to position and needle insertion and the associated complications were recorded.

Conditions

• Nerve Pain

Interventions

Type	Name	Description
PROCEDURE	popliteal block	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
