Total Parenteral Nutrition (TPN), a form of central venous nutrition therapy, is used when the patient needs intensive nutritional support for an extended period. It is an exciting therapeutic intervention for the critically ill patient, as well as for the patient with permanent small bowel dysfunction requiring long-term nutrition support. Nurses must play a vital role in supporting the optimal response to parenteral nutrition therapy, minimizing complications; understand the macronutrient and micronutrient components of TPN, indications and rationale for use, and proper administration techniques.Authors had an immense interest in publishing this book for global nurses for their knowledge updating. This research-based book will give the best knowledge about Total Parenteral Nutrition all around.
