Background:
High-volume local infiltration analgesia has been shown to be an effective pain treatment after knee replacement, but the role of bandaging to prolong analgesia has not been evaluated.
Methods:
48 patients undergoing fast-track total knee replacement with high-volume (170 mL) 0.2% ropivacaine infiltration analgesia were randomized to receive a compression or a non-compression bandage, and pain was assessed at rest and with mobilization at regular intervals for 24 h postoperatively.
Results:
Pain at rest, during flexion, or on straight leg lift was lower for the first 8 h in patients with compression bandage than in those with non-compression bandage and with a similar low use of oxycodone. Mean hospital stay was similar (2.8 days and 3.3 days, respectively).
Interpretation:
A compression bandage is recommended to improve analgesia after high-volume local infiltration analgesia in total knee arthroplasty.

Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...
