US-Guided Truncal Regional Nerve BlocksIn Abdominal Surgery

Postoperative pain is severe in patients undergoing abdominal surgery, and severe pain not only affects therate of recovery of patients but also induces a series of pathophysiological reactions which increase hospitalstay. Therefore, it is very important for perioperative patients period to have a safe and effective painmanagement model.Epidural Analgesia traditionally been used in intra-abdominal surgery, but concerns with this technique includehypotension, motor block, and the risk of neurological damage, particularly in the presence of anticoagulant orantiplatelet therapy. Abdominal wall blocks avoid the risks and adverse effects of central neuraxial blockadeand provide a relatively safe alternative to Epidural Analgesia.Recently, with the rise in enhanced recovery after surgery, nerve blocks have become the key link inmultimodal analgesic regimes. The truncal nerve blocks, as a part of perioperative pain management, wereintroduced into clinical practice over ۴۰ years ago. As effective constituents of multimode analgesia, thetruncal nerve blocks are mainly used for postoperative analgesia in abdominal surgery.With progression in US guided blocks in regional anesthesia setting, newer and safer truncal blocks have beenintroduced for postoperative pian control.In this presentation I try to have a look on different US guided truncal nerve blocks.
