Efficacy of dexmedetomidine addition to bupivacaine on the quality of blind fascia iliaca compartment block in children undergoing femur fracture surgery.
Objectives
The 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.
Methods
This study was conducted on 28 children (2–6 years of age), scheduled for fracture femur surgery. Children were randomly allocated to receive either 0.25% bupivacaine 1 ml kg (B group), or 0.25% bupivacaine 1 ml kg with dexmedetomidine 2 μg kg (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.
Results
Compared 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 24 h postoperatively and less number with postoperative agitation. No patients developed postoperative respiratory depression, purities, hypotension or bradycardia.
Conclusion
The 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.
