Randomized Controlled Trial Clinical TrialA randomized trial of endoscopic and fluoroscopic placement of postpyloric feeding tubes in critically ill patients.
Early postpyloric feeding is considered the accepted method of nutrition support in critically ill patients. Endoscopic and fluoroscopic techniques are associated with the highest percentage of successful placement. The purpose of this study was to compare endoscopic vs fluoroscopic placement of postpyloric feeding tubes in critically ill patients. ⋯ Endoscopic and fluoroscopic placement of postpyloric feeding tubes can safely and accurately be performed at the bedside in critically ill patients. Our results showed no significant difference in the success rate or time of placement between endoscopic vs fluoroscopic placement of postpyloric feeding tubes.

Accuracy of methods to estimate ionized and "corrected" serum calcium concentrations in critically ill multiple trauma patients receiving specialized nutrition support.
The purpose of this study was to determine the accuracy of 22 published methods to estimate serum ionized calcium (iCa) and "corrected" total serum calcium (totCa) concentrations in critically ill, multiple trauma patients. Seven of these formulas estimated iCa and 15 were directed toward predicting a "corrected" totCa. ⋯ Aberrations in calcium homeostasis are frequent (27%) in postresuscitative critically ill multiple trauma patients. Methods for predicting hypocalcemia lack sensitivity and are often associated with an unacceptable rate of false negatives. Predictive methods for estimating ionized or corrected serum concentrations should not be used. Direct measurement of serum iCa concentration is indicated for assessing calcium status for this population.

Education and evidence are needed to improve neonatal parenteral nutrition practice.
Parenteral nutrition (PN) is an essential component of neonatal care for those infants who are unable to tolerate adequate enteral feeding. Its use is not without complications such as biochemical derangements, sepsis, thrombosis, extravasation of fluid, and death. Such complications can be reduced by meticulous management of PN in response to biochemical abnormalities, nutrition teams, policies to reduce sepsis, and staff training to be more aware of pericardial and pleural effusions. We ascertained the current practices in PN administration and management of complications in all neonatal units with 6 or more intensive care cots in England, Scotland, and Wales. ⋯ There is a diverse practice and knowledge with a concerning lack of education in nutrition among the middle grade doctors in England, Scotland, and Wales. The management of common complications such as sepsis and hyperglycemia are highly variable. Improved staff training and production of unified evidence-based guidelines need urgent consideration.
