The knotting of continuous suprainguinal fascia iliaca catheter, a rare complication

Abstract

Continuous peripheral nerve catheters have become a standard approach for postoperative multimodal analgesia, offering effective pain management after various surgical procedures. This method is generally regarded as safe and has improved patient outcomes by providing targeted pain relief. While considered safe, there are potential complications associated with the procedure. One such complication is catheter entanglement. In this case, we encountered a patient with a catheter entangled in the suprainguinal fascia iliaca. We were able to resolve this issue by employing a meticulously applied continuous tension technique, allowing us to safely remove the catheter. The successful extraction of the catheter through a continuous tension technique highlights the importance of prompt recognition and appropriate management of complications associated with peripheral nerve catheters. While these complications are rare, anesthesiologists must be prepared to address them. This case serves as a reminder of the significance of vigilant monitoring and a comprehensive understanding of potential complications when employing continuous peripheral nerve catheters in postoperative care.
