MENDIOLA DE LA OSA, A. et al. Technical reliability of caudal block with ultrasound guided. []. , 21, 6, pp.323-327. ISSN 1134-8046.  https://dx.doi.org/10.4321/S1134-80462014000600005.

Introduction: Caudal block is a procedure used to treat lumbo-sacral root pain. This procedure has traditionally been realized using anatomy references or guided by fluoroscopy. The realization of sonography-guided technique and complications following the embodiment there of is presented. Material and methods: Observational and descriptive study in which is studied procedure complications. One hundred and twenty-six caudal blocks were performed in adult patients of both sexes. Procedure: The sacral hiatus was located by ultrasound and 18 G Tuohy needle was inserted into the epidural space flow drilling the sacro-coccygeal ligament. Results: There were no serious complications arose in any of the patients. There were no cases of poor ultrasound window so they could perform the technique on all scheduled patients. Conclusions: The procedure sonography-guided is safe and reliable due to the absence of complications and is an alternative to flouoroscopy-guided technique. This technique of ionizing radiation exposure is avoided. In addition the caudal block does not need ionized contrast substances and let take the sonography machine bedsides if necessary.
