Correct Gastric Tube Placement in Very Low Birth Weight Neonates: Comparison of NEX and NEMU Methods
Correct Gastric Tube Placement in Very Low Birth Weight Neonates: Comparison of NEX and NEMU Methods
Gastric tube (GT) placement is a recurrent procedure in VLBW infants due to feeding impairment correlated with low birth weight.
Correct GT depth is mandatory to ensure an appropriate and safe enteral feeding: X-ray is the gold standard in order to check GT position, but this cannot be routinely performed due to x-ray exposure risk. Feeding a neonate through a misplaced GT is potentially harmful and may increase morbidity, mortality and hospitalization length.
Nurses estimate GT depth through external measurements. This study aims to identify the most appropriate insertion length predictor for orogastric tube placement in VLBW infants by comparing two different methods.
Several methods have been suggested to estimate orogastric tube insertion length, but none of them has been validated in VLBW infants. The most commonly used methods are NEX (Nose-Ear-Xyphoid) and NEMU (Nose-Ear-Mid-Umbilicus) as predictors of nasogastric tube insertion. For the purpose of the present study NEX and NEMU methods were adjusted for orogastric tube placement.
Hence, primary aim of this study is:
To identify the most appropriate insertion length predictor for orogastric tube placement in VLBW infants by comparing NEX and NEMU methods.
Secondary aim is:
- To develop a new mathematical formula, based on the neonate's weight or length, to predict the insertion length of orogastric tube in VLBW infants
