Analgesia of children operated on the lumbosacral segments is discussed. Balanced total anesthesia was used with caudal epidural blocking by a combination of alpha 2-agonist clofelin, local amide anesthetic bupivacaine, and narcotic analgesic promedol. Injection of a combination of clofelin (0.01% solution) in a dose of 1 microgram/kg, standard dose of 0.25% bupivacaine solution with adrenaline (1:200,000) in a dose of 0.3 ml/kg, and promedol in a dose of 0.2 mg/kg into the epidural space via the caudal approach in the presence of superficial anesthesia with halothane (0.2-0.4 vol/%), nitrogen oxide and oxygen in 2:1 ratio ensured adequate analgesia and effective neurovegetative protection both during the operation and the first 25 h after it.
