The use of regional anesthetic techniques in the peri-operative period has increased as a means to improve analgesia and patient outcomes. Traditionally, various local anesthetics are used and addition of adjuncts such as epinephrine, clonidine, and dexamethasone has shown to prolong the block effect. There has been ongoing research to support the prolongation of a regional block with the addition of dexamethasone and dexmedetomidine (Dex-Dex), providing analgesia for multiple days. We present a case of a 35-year-old female who underwent an Achilles tendon repair with an adductor/popliteal nerve block. Both dexmedetomidine and dexamethasone were added to the local anesthetic mixture with substantial postoperative analgesic control. The patient also did not require any supplemental opioid medication. This case emphasizes the proposed synergistic effect of dexmedetomidine and dexamethasone when added to the local anesthesia injectate for lower extremity peripheral nerve blocks.

The discovery of the mechanism of action of local anesthetics, involving the blocking of sodium ion channels is considered a milestone in anesthesia. Potentially lethal toxic effects occur in the case of intravascular injection of local anesthetic (LA) or in case of exceeding dosages, as a result of systemic reabsorption. Attempts to prevent these life-threatening events have been made by developing novel LA and by adding adjuvants.

Background: Acute postoperative pain is one of the most common challenges faced by patients who undergo surgery. Multimodal analgesia has been recommended in recent years to effectively control this condition. Nerve blocks are an important part of multimodal analgesia; a single peripheral nerve block is widely used in clinical practice.

Purpose: β-amyloid overload-induced neuroinflammation and neuronal loss are key pathological changes that occur during the progression of Alzheimer's disease (AD). Dexmedetomidine (Dex) exhibits neuroprotective and anti-inflammatory effects on the nervous system. However, the effect of Dex in AD mice remains unclear, and its neuroprotective regulatory mechanism requires further investigation.

Pediatric regional anesthesia is evolving with new peripheral nerve blocks and techniques aimed at improving perioperative pain management. While caudal blocks have long been standard due to their simplicity and low complication rates, newer fascial plane blocks offer comparable efficacy with enhanced nerve coverage tailored to specific surgeries. Moreover, adjuncts like dexmedetomidine and dexamethasone have shown promise in prolonging block duration and enhancing post-operative pain relief and patient satisfaction.

Background: Acute pain is a major concern after arthroscopic shoulder surgery, supraclavicular brachial plexus blockade has shown favorable postoperative analgesic effects. However, its duration of analgesia does not meet clinical needs. We aimed to explore whether the combination of different local anesthetic adjunct can prolong the analgesic duration of supraclavicular brachial plexus block for arthroscopic shoulder surgery.
