Proper positioning eliminates patient injury

1. Pre-existing disorders such as poor nutritional state, diabetes, respiratory disorders arthritis, and cardiac status compound the effects of positioning. 2. Under anesthesia, the patient may be placed in a potentially injurious position that he could protect himself against otherwise. 3. Position influences respiration by mechanical restriction of the ribs and sternum, and by reduced ability of the diaphragm to push down against the abdominal contents. 4. Informed involvement of the operating room nurse will minimize risk to the patient who is defenseless under anesthesia.
