Background and Aims 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 in children.

Methods 44 children (12.6 ± 1.4 years) were included into the study. First group – 20 patients – received anesthesia by new QLB technique (figure 1) under ultrasound guidance with 0.5% bupivacaine hydrochloride.

20 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 (p < 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.
