Abstract
Postoperative pain following abdominal and pelvic surgeries is an
important issue that affects postoperative recovery. Although pain after surgeries
is multifactorial, pain relief increases patient satisfaction and comfort levels,
reduces perioperative inflammation, promotes rehabilitation, shortens the length
of hospitalization, and decreases the cost. In contrast, severe pain causes mental
disorders such as anxiety and depression. Traditionally, epidural blocks and
opioid consumption were used to alleviate pain; however, adverse effects such as
respiratory depression, nausea, vomiting, and itching left patients unsatisfied and
restricted their use. Therefore, multimodal analgesia and nonopioid systems were
developed to enhance recovery after surgery.
Recently, with the widespread use of ultrasonography, regional nerve
blocks have become an important part of multimodal analgesia regimes, which
show similar analgesic efficacy with favorable rates of side effects when
compared to opioids.
