Yu B, Hu X, Zou T, He M, Cai G - Med. Sci. Monit. (2015)

Bottom Line: We found no significant difference in analgesic effect between the 2 groups.Four (13.32%) out of 30 patients had failed catheter insertions in the Braun Group compared to none in the Cannula Group.The novel needle-over-cannula is effective, convenient, and safe in CFNB after TKA.

ABSTRACT

Background: The aim of this study was to compare the novel needle-over-cannula vs. the Braun continuous peripheral nerve block catheter set (Contiplex A) in postoperative analgesics after total knee arthroplasty (TKA).

Material and methods: Sixty patients undergoing total knee arthroplasty were randomly assigned to Braun continuous peripheral nerve block catheter set group (Braun Group, n=30) or the novel needle-over-cannula group (Cannula Group, n=30). All the patients in the 2 groups received continuous femoral nerve block (CFNB) for postoperative analgesics.

Results: We found no significant difference in analgesic effect between the 2 groups. The time of catheter or cannula insertion was shorter in the Cannula Group than in the Braun Group. Four (13.32%) out of 30 patients had failed catheter insertions in the Braun Group compared to none in the Cannula Group. Twelve (46%) out of 26 patients in the Braun Group had serious local anesthetic leakage at puncture sites during 12 h compared to none in the Cannula Group.

Conclusions: The novel needle-over-cannula is effective, convenient, and safe in CFNB after TKA.

Mentions: Although total knee arthroplasty (TKA) improves patients’ long-term quality of life, it often results in severe pain immediately after surgery, which is difficult to control solely with oral or intravenous analgesics. Postoperative pain of TKA is one of the most serious problems in clinics and is difficult to manage [1–3]. A patient who has a high level of post-TKA pain is more likely to have poor functional outcomes [4]. Multiple techniques of postoperative pain control have been used after TKA, including intravenous (IV) opioids, continuous epidural analgesia (CEA) [5,6], and continuous femoral nerve block (CFNB) [7–12]. Nerve block is the foundation of multiple pain management modalities in TKA and offers the potential benefit of extended postoperative analgesia; it has few adverse effects and allows faster rehabilitation compared with intravenous analgesia [13–17]. The Braun (Contiplex A) continuous peripheral nerve block catheter is widely used in China and many other countries and is very effective in peripheral nerve block analgesia. Nevertheless, it has many disadvantages, such as complicated procedure of catheter insertion, the tip of the catheter is not visible, and sometimes local anesthesia liquid leaks at the puncture site. A novel needle-over-cannula has been invented to solve these problems (Figure 1A). The novel needle-over-cannula (22-gauge needle, 90-mm length external indwelling cannula; Tuoren Group, Xinxiang, China) is an innovative product invented by Dr. Bin Yu, who is also the first author of the present article. The novel needle-over-cannula had an authorized patent in China, and a related patent had also been applied for in the U.S. (application number 14357772).
