['Although caudal and spinal blocks are modern and safe techniques, in many centers children still are operated on under general anesthesia (GA), or the blocks are used for postoperative analgesia after GA in infraumbilical operations. The authors aimed to document the results and the complications of 1,554 regional anesthesia cases, thereby assessing their validity.', 'The analysis of 1,459 caudal and 95 spinal blocks cases collected until January 2001 in children from newborn to 12 years of age are documented retrospectively. The types of anesthesia analyzed in the study were caudal block (CB) only, CB plus GA, GA plus CB, GA plus spinal block, and spinal block only.', 'There were 1,338 caudal and 95 spinal block cases that clinically were satisfactory. Because the duration of CB was not sufficient in 39 cases, GA was used. Failure to produce a CB occurred in 82 cases (5.57%). There were 257 of 1,338 patients operated on under GA and supported by caudal block for postoperative analgesia.'] Is regional anesthesia a good alternative to general anesthesia in pediatric surgery : Experience in 1,554 children?
