RESUMO
OBJECTIVE(S): This study was designed to evaluate the efficacy and safety of serratus anterior plane block (SAPB) as an analgesic technique for thoracotomies in pediatric patients. DESIGN: Double-blinded randomized controlled trial. SETTING: A single-center study at Aboelrish Pediatric Hospital, one tertiary hospital of Cairo University Hospitals. PARTICIPANTS: Seventy pediatric patients aged six months-to-three years scheduled for thoracotomies. INTERVENTIONS: Patients were randomized into two groups, group SF and group F. Group SF received an ultrasound-guided SAPB (n = 35), whereas group F (n = 35) did not. All groups received an intraoperative fentanyl infusion (at 0.5 µg/kg /h). MEASUREMENTS: The primary outcome was the total dose of postoperatively administrated fentanyl in the first 24 hours. The secondary outcomes included the total dose of intraoperative additional fentanyl boluses; time of the first postoperative rescue analgesia; and postoperative Face, Legs, Activity, Cry, Consolability scale (FLACC) score values. MAIN RESULTS: The main results of this study showed that the administrated fentanyl in the 24 hours postoperatively was significantly lower in SF group than in F group (p value Ë 0.001). In addition, significant decreases of the postoperative FLACC pain score (p value Ë 0.001), reduction of intraoperative fentanyl consumption (p value Ë 0.001), and delay of the first rescue analgesia (p value Ë 0.001) were recorded in SF group in relation to F group without significant complications in both groups. CONCLUSIONS: Serratus anterior plane block can provide a safe, effective, and easy-to-perform regional technique for children undergoing thoracotomies.
