Some parents have inquired whether hernia surgery can be performed on their children who have been found to have coarctation since birth and have not been managed surgically. This situation should be judged according to the type of co-morbidities and cardiac function of the child. Most co-morbidities can tolerate routine anesthesia for non-cardiac surgeries under the careful management of experienced anesthesiologists. It is inappropriate to stop surgery as soon as the child has co-morbidities. The anesthesiology daily study specifically includes the anesthesia management of non-cardiac surgery for co-morbid heart disease, which is still very much related to the skill level of the anesthesiologist.
