ObjectiveStudy of the correlation of feeding tolerance and gastric pH in very low birthweight infants, in order to provide the basis and reference of feeding intolerancecondition judgment and nursing care for clinical neonatal doctors and nurses.Method1.Convenience sampling, access to electronic medical records, hospitalizedVLBW information and data were collected in January2011-September2013of aneonatal intensive care unit, data integrity selected cases requiring hospitalization,birth weight≤1500g, very low birth weight infant and feeding tubes.2. Case-control study to follow the principle of proportionality, very low birthweight infants selected into groups of different feeding tolerance studies in addition toexternal factors, the mode of delivery, gestational age, birth weight, sex and physicalcondition of the mother, tube feedings time, intravenous nutrition for a few days, thenumber of days of hospitalization were needed to be balance comparable.3. According to the diagnostic criteria of whether there were feedingintolerance,divide into feeding tolerance group and the feeding intolerance group,according to the exclusion criteria and quality control and removed those did not meetthe criteria.4.The original hospital data for the two groups were compared, generalinformation on admission and during hospitalization clinical data, including mode ofdelivery, gestational age, birth weight, sex and physical condition of the mother, tubefeedings time, intravenous nutrition for a few days, the number of days ofhospitalization, gastrointestinal nutritional feeding tolerated: milk, feeding capacity,gastric pH, gastric residue, abdominal distension, vomiting and abnormal stools.5. Using SPSS17.0statistical software for statistical analysis, generalinformation using descriptive statistics, measurement data with a mean±standard deviation (x s) showed comparison between two sample t test,2test was used tocompare rates, Pearson correlation using linear correlation analysis, studies of verylow birth weight children with feeding intolerance correlation between gastric pHvalues,P<0.05was considered statistically significant.Results1.Feeding tolerance group and feeding intolerance group in the mode of delivery,gestational age, birth weight, sex and maternal health situation analysis, no statisticalsignificance (P>0.05), the two groups were comparable. Feeding tolerance group andfeeding intolerance tube feeding support group at the time, intravenous nutrition for afew days, the number of days of hospitalization analysis, no statistical significance (P>0.05),the two groups were comparable.2.86very low birth weight infant whose gastric pH between2~7. Of43feedingintolerance in infant whose gastric pH between2~7.43cases of infant with feedingtolerance gastric pH between3and7, the group of infant with feeding intolerancegastric pH levels higher than feeding tolerance group (t=10.74, P=0.00), feedingtolerance group mean pH value was3.05, the pH of feeding intolerance group meanof4.88.3. With the increase of gastric pH and increased gastric residual volume, lineartrend, Pearson correlation coefficient r=0.77, P=0.00, there is a positive linearcorrelation between the residual stomach and gastric juice pH, the more the residualamount of the stomach, gastric pH The higher the value, the less the amount of enteralfeeding; along with reducing the amount of residual stomach, gastric pH valuesdecrease, increase the amount of feeding, feeding intolerance symptoms corrected.Conclusion1.Very low birth weight infant with feeding intolerance group whose gastric pHlevels is higher than feeding tolerance group. 2. Very low birth weight infant with feeding intolerance is closely related to itsgastric pH.Infant with feeding intolerance whose gastric residual is increased. Themore the residual amount of the stomach, the higher gastric pH levels.3. The stomach residual and gastric pH is positive linear correlation in very lowbirth weight infant. The more residual stomach, the higher gastric pH. |
