Effects of Postoperative Continuous Femoral Nerve Block Analgesia with Braun Continuous Peripheral Nerve Block Catheter Set versus Novel Needle-Over-Cannula after Total Knee Arthroplasty.

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.

f4-medscimonit-21-1843: After the needle was pulled out and the cannula was fixed to the skin with no-pressure medical tape.

Mentions: In the Cannula Group, the transducer was also parallel to the arcus cruralis. The puncture point was 1 cm below the transducer at the lateral of femoral nerve 0.5 cm to avoid nerve injury. The novel needle-over-cannula was inserted out-plane at an angle of about 30° to skin, vertical to the arcus cruralis, and parallel to the femoral nerve (Figure 2). There was a double click when breaking through the fascia iliaca and fascia lata. After breaking through the 2-layer fascias, we injected 20 ml 0.5% ropivacaine to create a perineural fluid space with ultrasound guidance (Figure 3). Then the needle kept still, and the cannula was inserted forward 3–4 cm, then we pulled the needle out and fixed the cannula to the skin with no-pressure medical tape (Figure 4). The cannula could be observed clearly in the ultrasound image (Figure 5). A liquid area appeared at the tip of cannula when injecting normal saline through the injection interface, which could also be connected to the analgesia pump after the operation.
