- W2130029140 abstract "The indications for initiating total parenteral nutrition (TPN) were prospectively evaluated in 100 consecutive patients at a tertiary referral hospital with a long-standing Nutritional Support Service to illustrate the reasons why the parenteral route was chosen at this unique institution in terms of patient population. Sixty male and 40 female patients, average age 59 ± 17 years (range 22–86 years), were classified a priori as to the underlying reasons for initiation of TPN. The study was conducted by a Nutrition Support Service at this hospital without pediatric, trauma, or burn services specializing in the care of patients with diabetes mellitus. Of the 100 patients, 63% were from the surgical service; 24% had diabetes mellitus. Their mean weight (118 ± 29% of ideal), body mass index (25 ± 6 kg/m2), and serum albumin (2.8 ± 0.7 g/dL) indicated a reasonable body composition with a moderate systemic inflammatory response. Six patients received preoperative TPN for an average of 5 ± 3 days with a variety of diagnoses including malignancy, Crohn’s disease, bowel obstruction, and gastrointestinal bleeding. The underlying reasons for initiating nutritional support were related to three factors that largely determine the need for involuntary feeding: preexisting protein calorie malnutrition, actual or anticipated semistarvation for a prolonged period, and the presence of a systemic inflammatory response. The choice of TPN was based on anticipated or proven intolerance to full enteral feeding. The duration of time before initiation of TPN postoperatively was 6 ± 5 days, which reflects our policy that initially well-nourished patients who are experiencing a systemic inflammatory response should not undergo more than 5 to 7 days of inadequate feeding. The duration of TPN overall was 11 ± 10 days, which primarily illustrates the dramatic reduction in length of hospital stay that has occurred throughout the health care system and the willingness to provide TPN in alternative settings including transitional care units, rehabilitation hospitals, and for short-term care, the patient’s home. The most common specific reasons identified for initiating TPN rather than enteral nutrition were ileus (25%), an underlying acid-base or electrolyte/mineral disorder (13%) requiring correction, and the convenience of TPN because a central venous catheter was in place (12%). The usual indication for nutritional support at this tertiary referral and specialty hospital was actual or impending protein calorie malnutrition. TPN was chosen for a variety of reasons related to actual or anticipated tolerance to enteral feeding. This audit demonstrates that our TPN practice has evolved in relation to time of initiation and duration of feeding, which reflect a clearer appreciation of the risks and benefits of TPN." @default.
