recommended for procedures lasting 40 minutes or less.\n\nDexamethasone is commonly used during anesthesia for the prevention of postoperative nausea and vomiting and has also been shown to prolong the duration of analgesia and sensory block after regional anesthesia.\n\nDexamethasone may therefore extend the duration of chloroprocaine spinal anesthesia, potentially allowing its use for longer surgical procedures while maintaining the benefits of rapid postoperative recovery.\n\nThis study aims to evaluate whether intravenous dexamethasone can prolong the effects of spinal anesthesia performed with chloroprocaine in adults undergoing knee arthroscopy.",[79],"Knee Arthroscopy",[81,82,83,84,85,86],"Knee arthroscopy","dexamethasone","chloroprocaine","spinal anesthesia","sensory
