Caudal and intravenous dexamethasone as an adjuvant to pediatric caudal block: A systematic review and meta‐analysis

Abstract: Caudal and intravenous dexamethasone could provide longer duration of postoperative analgesia and reduced the incidence of postoperative vomiting with comparable adverse effects than plain caudal block. However, any additive to the caudal space carries with it the potential for neurotoxicity and that caution should always be exercised when weighting the risks and benefits of any additive. The result was influenced by small numbers of participants and significant heterogeneity.

“…Moreover, dexamethasone has both local and systemic mechanisms to prolong the analgesic duration of LAs [ 39 ]. The local mechanism may stem from the fact that dexamethasone can delay the absorption of LAs by constricting the blood vessels and reducing capillary permeability [ 40 ]; the systemic mechanism is likely due to the fact that dexamethasone can inhibit the local cyclooxygenase activity in trauma and reduce the synthesis of pain-causing substances, such as prostaglandins, thus exerting analgesic effects [ 41 ]. Mao et al [ 42 ] compared the efficacy of perineural dexamethasone with ropivacaine for TPVB in patients undergoing elective thoracotomy.…”

“…Several additives, such as dexamethasone and alpha-2-adrenergic receptor agonists, have been shown to prolong analgesia following peripheral nerve blocks with single doses and give the potential extent for pain beyond the provision of a single-shot nerve block (26). Therefore, in our study, we decided to use dexamethasone with the best-proven effectiveness (27,28).…”

“…Systemic toxicity in children also continues to be a topic of concern. The consensus is that the traditional method of general anesthesia can be improved with reduced use of opioids or opioid-free therapy [6,12,13].…”
