Brief Summary:
Caudal block is one of the most useful and popular regional block in pediatric anesthetic practice. Successful caudal block depends on the proper placement of a needle through sacral hiatus by following anatomical landmarks. The sacrum and the position of sacral hiatus are extreme variable anatomical structure. Generally, the equilateral triangle located between the apex of the sacral hiatus and posterior superior iliac spines is used in determining the location of the sacral hiatus as the conventional method. Previous study demonstrated that the triangle formed between the apex of the sacral hiatus and the posterior superior iliac spines was found to have the features of an equilateral triangle in adult. There is no study about the efficacy of the conventional method using the equilateral triangle in children. In this study, the investigators will compare between the expected site of sacral hiatus by conventional method using the equilateral triangle and the real site of the sacral hiatus confirmed by ultrasonography for caudal block in children.
