PHPR 2813 Study Guide - Catheter, Thrombophlebitis, Osmotic Concentration
Document Summary
Indications for pn: ensure indication is appropriate, ensure access is in place and documented, estimate total caloric needs, determine protein needs, determine lipid and carbohydrate amounts, micronutrients, determine total volume and initial rate, develop titration and monitoring plan. Logistics for pn: gi is unable to absorb nutrients, cancer patients, severe pancreatitis who is not candidate for en, critical care patient, perioperative for malnurourished, eating disorders. Long term access: non-tunneled catheter is most common catheter tip terminates in vena cave or right atrium, utilized for vasopressors andothers, peripherally inserted central catheter (picc) is commonly inserted for nutrition. Protein: provides 4 kcal/gram, should be 15-20% of total kcal, concentration grams/total volume. Lipids: provides 10 kcal/gram, typically, 30% of total kcal, able to be mixed w/ tpn or separate, holding lipids, 1 week for icu patients, fungal infections, propofol use, day of surgery, high tgs >400. Daily dosing: total calories x 0. 3 = calories from lipids, convert to grams of lipid, 10 kcal/gram.
