The use of an epidural approach (epidural anesthesia / analgesia, with or without an epidural catheter) remains the gold standard for analgesia after abdominal surgery. However, neuroaxial methods (epidural or intrathecal) are not possible in some patients, due to use of anticoagulant agents, coagulopathy, hemodynamic instability, and other contraindications to epidural space access (<a class="elsevierStyleCrossRef" href="#bib1">1</a>). On these occasions, alternative modes of analgesia are necessary, and peripheral techniques are reliable and beneficial.</p><p id="para20" class="elsevierStylePara elsevierViewall">The anterolateral abdominal wall is innervated by thoracolumbar nerves T6 to L1, through extensions of the intercostal, subcostal, ilioguinal, and iliohypogastric nerves. Branches of these nerves reach the anterior and lateral portions of the abdomen, passing through the intermuscular fascial planes, between the internal oblique (IO) and transverse abdominis (TA) muscles, reaching the midline after perforating the rectus abdominis muscle sheath (RAS) (<a class="elsevierStyleCrossRef" href="#fig1">Figure 1</a>) (<a class="elsevierStyleCrossRef" href="#bib1">1</a>,<a class="elsevierStyleCrossRef" href="#bib2">2</a>). This anatomical feature allows a local anesthetic to be injected into an intermuscular plane and its dispersion to reach the desired nerves. Ultrasound (US)-guided injection into an intermuscular plane is technically easier to perform than identifying specific peripheral nerves. This approach provides easy and versatile peripheral block techniques (<a class="elsevierStyleCrossRef" href="#bib3">3</a>).</p><elsevierMultimedia ident="fig1"></elsevierMultimedia><p id="para30" class="elsevierStylePara elsevierViewall">In this article, we will describe the most useful US-guided peripheral blocks for abdominal wall analgesia.</p></span><span id="cesec20" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="cestitle30">TRANSVERSUS ABDOMINIS PLANE (TAP) BLOCK</span><p id="para40" class="elsevierStylePara elsevierViewall">First described based on anatomical markers by Dr. Rafi (<a class="elsevierStyleCrossRef" href="#bib4">4</a>), the advent of US popularized the technique for its added safety.</p><span id="cesec30" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="cestitle40">Anatomy</span><p id="para50" class="elsevierStylePara elsevierViewall">The anterior branches of intercostal nerves T7 to T12 and the anterior branch of the spinal nerve L1 are responsible for innervation of the lower anterolateral abdominal wall and are arranged in the plane between the IO muscle and the TA muscle (<a class="elsevierStyleCrossRefs" href="#fig1">Figures 1 and 2</a>) (<a class="elsevierStyleCrossRef" href="#bib3">3</a>,<a class="elsevierStyleCrossRef" href="#bib5">5</a>).</p><elsevierMultimedia ident="fig2"></elsevierMultimedia></span><span id="cesec40" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="cestitle50">Indications</span><p id="para60" class="elsevierStylePara elsevierViewall">Analgesia for lower abdominal and infra-umbilical surgeries: Pfannenstiel incision, abdominal hysterectomy, cesarean section, herniorrhaphy, correction of orchidopexy, appendectomy, cystostomy, lower middle laparotomies, and retropubic prostatectomy (<a class="elsevierStyleCrossRefs" href="#bib6">6–9</a>).

Under US view, three well-defined muscle planes can be identified below the skin and subcutaneous tissue: external oblique muscle (EO), IO muscle, and TA muscle. The IO muscle is usually the most prominent of the three. Below the third muscle plane, moving structures (viscera with peristalsis, respiratory movement within the abdominal cavity) are noted (<a class="elsevierStyleCrossRef" href="#fig4">Figure 4A</a>). If it is difficult to visualize the three muscle planes, the probe should be slid to the midline, and the rectus abdominis (RA) muscle will be easily identified as a fusiform muscle surrounded by its sheath. By slowly sliding the probe in a lateral direction from the RA, in its lateral border (where the linea semilunaris is formed), the medial edge of the OI muscle is visualized. When good visualization of the three muscle planes is obtained, a 20-22G needle, 90-100 mm in length, should be introduced in-plane from medial to lateral, aiming to place its tip in the fascial plane between the IO and TA muscles (<a class="elsevierStyleCrossRef" href="#fig4">Figure 4B</a>). To facilitate needle visualization, it is possible to inject saline fractions (1-2 mL) for local hydrodissection. With the needle in place, 15-20 mL of local anesthetic (Ropivacaine 0.25%-0.5%, Bupivacaine 0.25%-0.5%, Levobupivacaine 0.25%-0.5%) should be injected after negative aspiration for blood or other materials. The correct injection site is confirmed by visualization of the spread of hypoechoic fluid between the OI and TA muscles (<a class="elsevierStyleCrossRef" href="#fig4">Figure 4C</a>).

However, these routes are not always available. In these cases, there are several options for regional anesthesia with the property of providing satisfactory postoperative analgesia for abdominal surgeries. The blocks described were already used in regional anesthesia, even before the advent of US, by techniques based on anatomical surface markers and fascial sensations of clicks. However, practice and evidence suggest that US-guided regional anesthesia techniques are safer and more effective, allowing greater use of specific blocks with their benefits when epidural or spinal anesthesia are not viable options.</p></span><span id="cesec280" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="cestitle290">AUTHOR CONTRIBUTIONS</span><p id="para360" class="elsevierStylePara elsevierViewall">Fernandes HS was responsible for the literature review, pictures production, and manuscript writing.
