Role of Caudal Blockade in the Modulation of Stress Response in the Surgical Correction of Congenital Malformations of the Lower Parts of the Urogenital System in Children

Objective: to assess the efficiency and safety of an anesthetic technique during the surgical correction of congenital malformations of the lower departments of the urogenital system in children by means of the comparative analysis of laboratory and hemodynamic indices, as well as the course of the early postoperative period, development of adverse effects during the anesthesia. Material and methods. Depending on the type of anesthesia, all patients (127 boys) were divided into 3 clinical groups: those operated under multicomponent balanced inhalation anesthesia (group 1, n = 37), under general laryngeal mask anesthesia in combination with caudal blockade with a local anesthetic solution (group 2, n = 45), under general laryngeal mask anesthesia with caudal blockade with the combination of a local anesthetic solution and adjuvant (group 3, n = 45). Results. The performed analysis of the parameters of hemodynamics, levels of cortisol, glucose, lactate and interleukin-6 (IL-6), as well as the quality, duration, depth of anesthesia and the necessity for an inhalation anesthetic, the assessment of complications and the adverse effects have revealed statistically significant differences indicative of a more effective blockade of the pain sensitivity in the combined application of general and regional anesthesia. Conclusion. The technique of combined anesthesia with the application of the combination of 0.25 % bupivacaine solution and adjuvant to 0.1 % morphine has shown the best efficiency and safety during the surgical correction of congenital malformations of the lower departments of the urogenital system in the children.
