Neonates require a full preoperative
assessment to determine the extent of the bladder exstrophy and the presence
of any other associated congenital abnormalities. Laboratory investigations
should include a complete blood count, blood glucose, urea, and
electrolytes, including calcium and phosphate. Renal and liver function
tests, a clotting screen, and cross-matching of blood should be obtained.
The cardiovascular status and state of fluid hydration should be assessed
because the condition is associated with marked fluid losses prior to
correction. Older children likely will have undergone several operations and
will benefit from sedative premedication. Latex allergy may be a problem in
children who have undergone several urologic or plastic reconstructive
procedures. Use of a latex-free anesthesia and surgery equipment is recommended.
