Caudal anaesthesia

Hello Awesomites!

Caudal anesthesia is a type of epidural anesthesia. 

INDICATIONS
The indications for single shot CA are abdominal,urologic or orthopedic surgical procedures located in the sub-umbilical abdominal, pelvic and genital areas, or the lower limbs, where postoperative pain does not require prolonged strong analgesia. Examples include inguinal or umbilical herniorrhaphy, orchidopexy, hypospadias and club foot surgery.

Anatomical landmarks (Figure)
The sacrum is roughly the shape of an equilateral triangle,with its base identified by feeling the two
posterosuperior iliac processes and a caudal summit corresponding to the sacral hiatus.The sacral hiatus is located at the caudal end of the median crest and is created by failure of the S5 laminae
to fuse (Figure). The hiatus is surrounded by the sacral cornu.

Preparation
Obtain consent for the procedure either from the patient or, if appropriate, from the parents. After induction of general anaesthesia and airway control, the patient is positioned laterally (or ventrally),
with their hips flexed to 90°. Skin disinfection should be performed carefully, because of the proximity to the anus.
After defining the bony landmarks of the sacral triangle, the two sacral cornuae are identified by moving your fingertips from side to side.The gluteal cleft is not a reliable mark of the midline. The puncture is performed between the two sacral cornuae. The needle is oriented 60° in relation to back plane, 90° to skin surface. The needle bevel is oriented ventrally, or parallel to the fibers of the sacro-coccygeal ligament.
After verifying absence of spontaneous reflux of blood or cerebrospinal fluid (more sensitive than an aspiration test), injection of LA should be possible be without resistance. Inject slowly (over about one minute).
