Post-Operative Impact of Nasogastric Tubes on Rates of Emesis in Infants Diagnosed With Pyloric Stenosis

2010-07-15 17:00:00 | BioPortfolio


The overall objective of this research study is to determine the effect of a pre-operatively placed nasogastric tube compared to no nasogastric tube, on post-operative emesis rates and postoperative length of stay in infants with a primary diagnosis of pyloric stenosis treated with pyloromyotomy. This study will also examine the feasibility data of the pilot data to develop estimates of treatment effect of a pre-operative nasogastric tube on post-operative rate of emesis and length of stay to be used to determine the sample size of the definitive trial.

Comparison Between Gastric and Post Pyloric Tube Feedings in Children With Bronchiolitis Requiring High Flow Nasal Cannula

The purpose of the study is to compare two ways (nasogastric tube (NGT) and nasoduodenal tube (NDT)) to provide nutrition to infants admitted to the hospital for viral bronchiolitis and wh...

Laparoscopic Versus Open Pyloromyotomy for Infants With Idiopathic Hypertrophic Pyloric Stenosis

Pyloric stenosis is a condition that develops in infants and that leads to an obstruction of the channel going out of the stomach. This study is being performed to determine if there is a...

Frequency of Formula Change Prior to the Accurate Diagnosis of Pyloric Stenosis

The purpose of this study is to determine if there is an increase in the frequency of formula change in patients with pyloric sctenosis prior to being correctly diagnosed.

Impact of the Absence of Nasogastric Decompresssion After Pancreaticoduodenectomy

The use of nasogastric (NG) decompression after pancreaticoduodenectomy (PD) is a current practice. NG tube is associated with a high rate of morbidity including pulmonary morbidity, delay...

The Impact of Nasogastric Indwelling Versus Oral Intermittent Tube Feeding Methods on Premature Infants

This clinical pilot trial is being conducted to learn more about the infant's feeding behavior while being fed by indwelling nasogastric tube placement or by intermittent oral tube placeme...

Retrospective Cohort Study on the Optimal Timing of Orogastric Tube/Nasogastric Tube Insertion in Infants With Pyloric Stenosis.

Hypertrophic pyloric stenosis in infants can cause a buildup of gastric contents. Orogastric tubes (OGTs) or nasogastric tubes (NGTs) are often placed in patients with pyloric stenosis before surgical...

Nasogastric Tube Syndrome: A Diagnostic Dilemma.

Nasogastric tubes have been used in the pediatric age group to supplement nutrition in cases of malignancy and failure to thrive due to a variety of causes. Breathing difficulty may occur after the in...

The Application of Pyloric chisel in the Treatment of Hypertrophic Pyloric Stenosis by Single-Site Umbilical Laparoscopic Pyloromyotomy.

The feasibility and perspective of pyloric chisel were discussed through the comparison of pyloric chisel and knife in the treatment of hypertrophic pyloric stenosis (HPS) in single-site umbilical lap...

Transected nasogastric tube: a rare complication of nasogastric feeding.

Association between exposure to macrolides and the development of infantile hypertrophic pyloric stenosis: a systematic review and meta-analysis.

Macrolides are bacteriostatic antibiotics with a broad spectrum of activity against Gram-positive bacteria. The aim of this study was to systematically review and meta-analyze the association between ...

Medical and Biotech [MESH] Definitions

Narrowing of the pyloric canal with varied etiology. A common form is due to muscle hypertrophy (PYLORIC STENOSIS, HYPERTROPHIC) seen in infants.

Surgical incision of the PYLORUS used to treat pyloric stenoses (e.g. INFANTILE HYPERTROPHIC PYLORIC STENOSIS).

Narrowing of the pyloric canal due to HYPERTROPHY of the surrounding circular muscle. It is usually seen in infants or young children.

Nutritional support given via the alimentary canal or any route connected to the gastrointestinal system (i.e., the enteral route). This includes oral feeding, sip feeding, and tube feeding using nasogastric, gastrostomy, and jejunostomy tubes.

A pathological constriction that can occur above (supravalvular stenosis), below (subvalvular stenosis), or at the AORTIC VALVE. It is characterized by restricted outflow from the LEFT VENTRICLE into the AORTA.
