Regional anesthesia is commonly used after surgery and plays an important role in
managing postoperative pain. Even with progress in surgical and anesthetic
techniques, many patients still experience noticeable pain following their
procedures. This pain may delay early movement, raise the risk of complications,
and lead to a longer hospital stay. Regional anesthesia stops pain signals before
they reach the central nervous system. Because of this, patients usually feel less pain
and need fewer opioids. The effectiveness can vary and depends on the patient's
condition, the type of surgery, and the regional technique used. Each method—
neuraxial anesthesia, peripheral nerve blocks, and fascial plane blocks—has its own
benefits, but their clinical effect may differ between patients. Although
complications such as local anesthetic toxicity or nerve injury are rare, they still
need to be kept in mind. The purpose of this narrative review is to summarize
current knowledge on postoperative pain mechanisms, explain how regional
analgesia works, and describe the main techniques of regional anesthesia used in
clinical practice, along with their benefits, limitations, and their role in ERAS
protocols.
