Children with cardiac problems are known to get fatigued with minimalphysical exertion. This situation is more apparent for cases that undergooperative procedures. Adequate nutritional support and better nutritionalstatus have been shown to improve physiological stability and minimizecomplications in PICU. This research aims at conducting a survey on advances innutritional support for post-operative cardiac pediatric patients. Nutrition currently plays a major role in reducing mortality rate at pediatricintensive care units. Evidence shows that feeding enhances immunity,sustains organ function, minimizes starvation effects, prevents nutritionaldeficiencies, supports the patient's disease state until the acute–phase inflammatoryresponse resolves and shortens recovery time. There is an increased interest howeverin defining nutritional support protocols. A survey is conducted on literaturepublished during the last ten years on the subject of nutritional support in PICUs ofpost-operative cardiovascular cases. Surveyed literature covered various aspects including: enteral and parenteralnutrition as well as new findings in nutrition support for post-operativepediatric cardiac patients. Multivitamin and trace-element preparations arewidely available. Individual patients may require additional supplements of certainmicronutrients. Essential fatty acids are provided through weekly infusion of acommercial fat emulsion. Sulfur compounds as glutathione are used for their abilityto modulate the redox status of the cell
