SRJ is a prestige metric based on the idea that not all citations are the same.

Introduction Acids during gastro-esophageal reflux GER have been considered the main cause for gastro-esophageal reflux disease GERD in infants 1a disease which manifests with digestive and extra-gastrointestinal symptoms such as apnea and apparent life threatening episodes ALTE 2. No patients had previously received either antacids or prokinetic treatments.

Normal values of h ambulatory intraluminal impedance combined with pH-metry in subjects eating a Mediterranean diet. Am J Gastroenterol ; Mediante IIM se registraron 8. Twenty-four-hour esophageal impedance-pH monitoring in healthy preterm neonates: A value of p less than 0.

Multichannel intraluminal impedance MII -pH-testing could prove advantageous impedanciometriq the detection of acid reflux and non-acid reflux, the clearing times for these and the progression distances up the esophagus. The researcher is required to dedicate, on average, somewhere between 30 minutes and 4 hours 21 for the interpretation of results for this test.


In consideration of this, a comprehensive study of this group of infants is necessary with the goal of ruling out GER as the etiology. However, multichannel intraluminal impedance MII esofagjca provide advantages. Recent studies have shown that, in spite of a decline in instances of sudden infant death syndrome SIDSprimarily due to the reduction in popularity of placing the infant in the prone position to sleep, the frequency of hospital admissions for ALTE have remained the same 6.

The sensitivity of multichannel intraluminal impedance and the pH probe in the evaluation of gastroesophageal reflux in children. The relationship between GER and obstructive or mixed apnea is more convincing during waking hours, in the supine position or within an hour of having been fed.

After the clinical data was taken and the complementary tests were done on each patient, we have a total of 18 cases which were finally diagnosed with gastro-esophageal reflux as the main cause impedanciomwtria ALTE Table III. Based on the area under the curve, values can be interpreted giving 0. In the same way, the combination of pH-testing and MII uses its individual channels to help characterize refluxed materials liquids, gases and mixed and the distance that the bolus travels in the esophagus.

The software used incorporated automatic analysis of the entries and easy-to-read and easy-to-interpret readouts.


Pediatric gastroesophageal reflux disease and acid-related conditions: Here the time for the esophagus to clear was 4. The average weight and length were 4. PH monitoring in the distal and proximal esophagus in symptomatic infants.

Due to its similarities to apnea of prematurity 4those infants whom have presented ALTE belong to a heterogenic group representing multiple pathologies, half of which are generally diagnosed with an underlying pathology where GER is one of the main impedajciometria 5.

Between andthe annual incidence for diagnosing GERD in infants less than one year old has tripled 3. Studies are still necessary to evaluate the normal standards for MII in pediatric patients.

Gastroesophageal reflux disease in neonates and infants: For this, the following parameters were taken into account: The Student’s t test and chi-squared test were used to compare the parametrical variables.

Various impesanciometria have been used to categorize reflux, allowing us to measure and assess the underlying problem imprdanciometria exposition time of the esophagus to gastric juices. Other parameters were also considered: Technical bases and clinical applications. This suggests that the combination of both techniques is better than MII or pH-testing alone.

Thirty nine patients were evaluated over this 3 year period.
