Suture-method versus Through-the-needle Catheters for Continuous Popliteal-sciatic Nerve Blocks A Randomized Clinical Trial

Conclusions Suture-type perineural catheters provided noninferior analgesia compared with traditional catheters for continuous popliteal-sciatic blocks after painful foot and ankle surgery. The new catheter design appears to be a viable alternative to traditional designs used for the past seven decades.Editor ’s PerspectiveWhat We Already Know about This TopicThe fundamental design of perineural catheters has changed little since they were first introducedWhat This Article Tells Us That Is NewA novel catheter attached to the back of a suture-shaped needle can be inserted under ultrasound guidance to provide popliteal-sciatic nerve blockadeIn the first two days after foot and ankle surgery, analgesia provided using the suture-type catheters was found to be noninferior to that provided by conventional through-the-needle catheters
