Abstract

AbstractEfficacy of dexmedetomidine addition to bupivacaine on the quality of blind fascia iliaca compartment block in children undergoing femur fracture surgery.ObjectivesThe objectives of this study were designed to detect the effects of addition of dexmedetomidine to bupivacaine on the quality of blind fascia iliaca compartment block and its possible side effects in children undergoing fracture femur surgery.MethodsThis study was conducted on 28 children (2–6years of age), scheduled for fracture femur surgery. Children were randomly allocated to receive either 0.25% bupivacaine 1mlkg−1 (B group), or 0.25% bupivacaine 1mlkg−1 with dexmedetomidine 2μgkg−1 (BD group). Anesthesia was maintained with sevoflurane 1–1.5 minimum alveolar concentration. Intraoperative sevoflurane concentration, hemodynamic, postoperative emergence delirium, sedation scores and pain scores were recorded. Duration of surgery and emergence time were recorded. Postoperative complications such as (nausea and vomiting, respiratory depression, purities, hypotension and bradycardia) were reported.ResultsCompared to the group B, patients received bupivacaine–dexmedetomidine for fascia iliaca compartment block had lower intraoperative sevoflurane concentration, higher sedation score, longer duration of postoperative analgesia, less use of rectal paracetamol for the first 24h postoperatively and less number with postoperative agitation. No patients developed postoperative respiratory depression, purities, hypotension or bradycardia.ConclusionThe present study concluded that the combined use of bupivacaine–dexmedetomidine for fascia iliaca compartment block in children provided significant reduction of end-tidal sevoflurane concentration, remarkable hemodynamic stability, significant postoperative analgesia with lower postoperative analgesics requirements without any undesirable complications
