Technique for caudal injection:
|
The needle is inserted at an angle of 70-80 degrees to the skin and slowly advanced until the bony resistance of the sacrum is detected. The needle is withdrawn slightly, the entry angle reduced by about half, and then reinserted to a depth of 2-3 cm, bearing in mind that the dural sac terminates at the S2 level. Note the proximity of the fetal head. |
