While regional anesthesia is the cornerstone of a multimodal program,
injecting local anesthesia into the surgical wound and surrounding soft
tissue is being used more in orthopedic surgery, says Dr. Settles.
In particular, there's been a growing use of pericapsular injections
for total knee replacement. In one recent study, researchers looked at
whether pericapsular injections of a mixture of bupivacaine, epineph-
rine, ketoprofen and morphine, along with placing a 4-day intra-articu-
lar catheter, offered any benefits over continuous femoral and single-
shot sciatic nerve blocks for total knee replacement patients. They
found that the injec-
tions and catheter
provided good pain
control without the
complications typical-
ly associated with
nerve block motor
weakness
(osmag.net/NDsSs2).
In another study,
researchers found
that using a mixture
of ropivacaine,
ketorolac, epineph-
rine and clonidine
