简要总结
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.
详细描述
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.

结局指标
主要结局
assessment of intraoperative and postoperative pain in different groups after intervention
时间窗: 24 hours after operation
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
