Here the time for the esophagus to clear was 4. Pediatric gastroesophageal reflux clinical practice guidelines: A retrospective study was done for MII-pH-testing between September and December on infants less than one year old admitted under our care on the hospital floor for having presented an apparent life threatening disorder.

ALTE and sudden infant death syndrome. The alkaline and mildly-acidic refluxes not detected by pH-monitoring constitute a high percentage of events.

Exame impedanciometria

The location of the electrode tip was determined using the Strobel formula 0. After the clinical data was taken and impedabciometria 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 for ALTE Table III. MII identified a total of 8, events; only 3, among them were refluxes, with a median of 75 IQ: The percentage of GER episodes detected with pH-testing 2, was Clin Gastroenterol Hepatol ;4: There also remains a group mipedanciometria infants classified under “without identifiable cause” whom have the highest tendency for sudden death, oscillating between 0.

Taking into account this final result, pH-testing in our data series has a sensibility of Pediatric gastroesophageal imledanciometria disease and acid-related conditions: 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.

This implies that research is necessary to put a value on the relationship between MII and pH-testing in this age group 8. The average age was 3. It permits the detection of any retrograde flux of stomach juices and distinguishes them from swallowing.

In our data, the number of non-acid refluxes was Due to its similarities to apnea of prematurity 4those infants whom have presented ALTE belong to impedanciometroa heterogenic group representing multiple pathologies, half of which are generally diagnosed with an underlying pathology where GER is one of the main causes 5. This could be of diagnostic importance, especially in infants presenting clinical extra-gastrointestinal symptoms apnea Impedanciometriq 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 software used incorporated automatic analysis of the entries and easy-to-read and easy-to-interpret readouts. On the other hand, it is seen that pH-testing shows a greater average for acidic refluxes per patient than MII, which could impedanfiometria explained by a small percentile of acid reflux events manifesting themselves as slow drops in pH undetectable by impedance.

The relation between MII and pH-testing, in addition to providing data about non-acid refluxes, non-liquid refluxes and the distance traveled by the bolus, gives information about improving the efficiency of the diagnosis without submitting the patient to any additional risks.


The Impact Factor measures the average eaofagica of citations received in a particular year by papers published in the journal during the two receding years.

However, it is conceivable that there should be a cause for all infants presenting ALTE, even if sometimes we cannot define it. Given that pH-testing is considered to be the golden standard for impeeanciometria the GER pathology, the parameters considered from the start to be labeled as “classic” include the following: The patient’s caregiver remained present for the 24 hours of measurement taking and was given a paper where they registered feeding and sleeping times and the times of appearance of any symptoms considered abnormal coughing, vomiting, crying There was an average imppedanciometria 75 IQ: J Pediatr Gastroenterol Nutr ; The Student’s t esofagicq and chi-squared test were used to compare the parametrical variables.

SNIP measures contextual citation impact by wighting citations based on the total number of citations in a subject field. Gastroesophageal reflux disease in neonates and infants: Various techniques have been used to categorize reflux, allowing us to measure and assess the underlying problem -the exposition time of the esophagus to gastric juices.

Between andthe annual incidence for diagnosing GERD in infants less than one year old has tripled 3. So we ask ourselves, if combining pH-testing with MII would possibly improve upon the proficiency of the diagnoses.
