Innervation of the Abdominal Wall and Viscera A1 - Beaussier, Marc A2 - Atchabahian, Arthur A2 - Gupta, Ruchir PY - 2013 T2 - The Anesthesia Guide AB - Recent findings emphasize the “two-wound model” after abdominal surgery: The somatic wound corresponds to the abdominal wallThe autonomic wound corresponds to the peritoneal layer and visceral componentPain after abdominal surgery arises predominantly from parietal somatic afferents, making parietal blocks very effectivePeritoneal and visceral sensory innervation is provided by visceral afferents running along the sympathetic nerves and joining the dorsal horn at the higher thoracic levels. However, a significant part of these afferents may reach the central nervous system by the vagus nerve, and will not be blocked even by an epidural block SN - PB - The McGraw-Hill Companies CY - New York, NY Y2 - 2024/10/12 UR - accessanesthesiology.mhmedical.com/content.aspx?aid=57262942 ER -
