The anterior cingulate cortex (ACC) plays a crucial role in the perception of pain. It is consistently activated by noxious stimuli and its hyperactivity in chronic pain indicates plasticity in the local neuronal network. However, the way persistent pain effects and modifies different neuronal cell types in the ACC and how this contributes to sensory sensitization is not completely understood. ⋯ Accordingly, it was sufficient to enhance the excitability of these neurons chemogenetically in the inflammatory pain condition to induce hypoalgesia. These findings suggest a cell type-specific effect on the descending control of nociception and a cellular mechanism for pain-induced analgesia. Furthermore, increased excitability in this neuronal population is hypoalgesic rather than hyperalgesic.

ReviewMultimodal analgesic strategies in polytraumatized patients.
In recent years, the resuscitation of trauma patients has improved; however, pain related to trauma remains associated with systemic complications. In trauma patients, pain should be considered a vital sign, and its control is crucial for reducing complications, improving patient satisfaction, and enhancing the quality of life. ⋯ In this review, we offer the reader an updated general framework of the various approaches available for pain treatment in polytraumatized patients, with a focus on the opportunities presented by regional anesthesia. We will examine different types of locoregional anesthesia blocks and describe ultrasonographic execution techniques.
