Biochemical stability during parenteral nutrition in children.
The aim of this study was to assess the frequency and importance of biochemical abnormality related to parenteral nutrition (PN) in a group of infants, and to devise an appropriate policy for routine biochemical surveillance. A standard monitoring protocol based on widely published guidelines was applied to 30 consecutive patients (age 3 days-3 years) referred to a children's hospital nutritional care team for PN. No serious biochemical abnormalities were observed to arise simply as a consequence of PN. Electrolyte disturbance most commonly occurred before starting PN. Biochemical abnormality was most likely to be found in patients with abnormal fluid and electrolyte losses. Protocols for biochemical surveillance during PN err on the side of caution and often suggest frequent and comprehensive testing. In stable patients such as the surgical newborn, this is both expensive and unnecessary, and simpler monitoring regimes may be used with safety.
