The main purported benefit of suture-style catheters is the ability to secure the catheter at 2 sites, thereby decreasing the likelihood of catheter dislodgement. An additional benefit is the ability to precisely control the placement of the orifice to infuse local anesthetic. ⋯ Despite multiple attempts, the catheter repeatedly advanced beyond the nerve. Placement of a suture catheter was then attempted, and the catheter was successfully placed on the first attempt.

Meta AnalysisAdductor canal blocks for postoperative pain treatment in adults undergoing knee surgery.
Peripheral regional anaesthesia techniques are well established for postoperative pain treatment following knee surgery. The adductor canal block (ACB) is a new technique, which can be applied as a single shot or by catheter for continuous regional analgesia. ⋯ We are currently uncertain whether patients treated with ACB suffer from lower pain intensity at rest and during movement, fewer opioid-related adverse events, and fewer accidental falls during postoperative care compared to patients receiving sham treatment. The same holds true for the comparison of ACB versus femoral nerve block focusing on postoperative pain intensity. The overall evidence level was mostly low or very low, so further research might change the conclusion. The 11 studies awaiting classification and the 11 ongoing studies, once assessed, may alter the conclusions of this review.
