Background: Regional anesthesia has a rapidly growing use in children over the recent two decades. An aim of our work is to suggest a new technique for quadratum lumborum block (QLB) and prove its efficacy compared to intravenous anesthesia.
Patients and methods: 34 children (10.6 ± 1.4 years) were included into the study. First group – 17 patients – received anesthesia by new QLB technique under ultrasound guidance with 0.5 % bupivacaine hydrochloride, 17 children received a continuous fentanyl intravenous infusion. Efficacy of postoperative analgesia was assessed through the complex of different vital signs; pain intensity was assessed by the Observation Scale for Infants and Small Children (VAS). Ethics Committee approved the conduct of the study. Statistical analysis was performed by a variation statistics method using “Statistica 5.5” soft and visualized through soft based on Python „Plotus XYZ”.

Results: The average pain score according to VAS was significantly lower in patients of the first group in early postoperative period at all stages of the study (р < 0.05). The average heart rate was lower than 120 bpm in group 1 for the entire time of QLB. Parameters of central hemodynamics, arterial blood flow in superior mesenterial artery and glucose levels were also normal.
Conclusion: Obtained data shows, that proposed new QLB technique is more effective, when compared to standard intravenous anesthesia.
Key words: local analgesia, pain, pediatrics, QL-block, ultrasound.
