Efficacy of Intravenous Dexamethasone in Prolonging the Duration of Spinal Anesthesia With Chloroprocaine in Knee Arthroscopy

Starting soon · Phase 3

Conditions studied: Knee Arthroscopy

In brief

Chloroprocaine is a short-acting local anesthetic that allows rapid recovery and early ambulation but is currently recommended for procedures lasting 40 minutes or less. Dexamethasone 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. Dexamethasone 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. This study aims to evaluate whether intravenous dexamethasone can prolong the effects of spinal anesthesia performed with chloroprocaine in adults undergoing knee arthroscopy.
