Correct Gastric Tube Placement in Very Low Birth Weight Neonates

2019-10-21 12:45:31 | BioPortfolio


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

Medical and Biotech [MESH] Definitions

Abnormal distention of the STOMACH due to accumulation of gastric contents that may reach 10 to 15 liters. Gastric dilatation may be the result of GASTRIC OUTLET OBSTRUCTION; ILEUS; GASTROPARESIS; or denervation.

A tube of ectodermal tissue in an embryo that will give rise to the CENTRAL NERVOUS SYSTEM, including the SPINAL CORD and the BRAIN. Lumen within the neural tube is called neural canal which gives rise to the central canal of the spinal cord and the ventricles of the brain. For malformation of the neural tube, see NEURAL TUBE DEFECTS.

Medical procedure involving the emptying of contents in the stomach through the use of a tube inserted through the nose or mouth. It is performed to remove poisons or relieve pressure due to intestinal blockages or during surgery.

Vagal denervation of that part of the STOMACH lined with acid-secreting mucosa (GASTRIC MUCOSA) containing the GASTRIC PARIETAL CELLS. Since the procedure leaves the vagal branches to the antrum and PYLORUS intact, it circumvents gastric drainage required with truncal vagotomy techniques.

Rounded or pyramidal cells of the GASTRIC GLANDS. They secrete HYDROCHLORIC ACID and produce gastric intrinsic factor, a glycoprotein that binds VITAMIN B12.
