Disuse of the GI tract has been associated with villous atrophy and generalized cell shrinkage.Translocation of bacteria from the local gut to systemic regions has been noted in relation to GI cell shrinkage,resulting in gram-negative septicemia.PN is administered in a variety of settings,including the patient's home.Patients in highly stressed physiological states such as sepsis,head injury,or burns are candidates for PN therapy.Safe administration of this form of nutrition depends on meticulous management of a central venous catheter.
