Evidence-based standardized nutrition protocol can shorten the time to full enteral feeding in very preterm/very low birth weight infants / 中国当代儿科杂志

OBJECTIVES@#To investigate whether evidence-based standardized nutrition protocol can facilitate the establishment of full enteral nutrition and its effect on short-term clinical outcomes in very preterm/very low birth weight infants.@*METHODS@#A retrospective analysis was performed on the medical data of 312 preterm infants with a gestational age of ≤32 weeks or a birth weight of <1 500 g. The standardized nutrition protocol for preterm infants was implemented in May 2020; 160 infants who were treated from May 1, 2019 to April 30, 2020 were enrolled as the control group, and 152 infants who were treated from June 1, 2020 to May 31, 2021 were enrolled as the test group. The two groups were compared in terms of the time to full enteral feeding, the time to the start of enteral feeding, duration of parenteral nutrition, the time to recovery to birth weight, the duration of central venous catheterization, and the incidence rates of common complications in preterm infants.@*RESULTS@#Compared with the control group, the test group had significantly shorter time to full enteral feeding, time to the start of enteral feeding, duration of parenteral nutrition, and duration of central venous catheterization and a significantly lower incidence rate of catheter-related bloodstream infection (P<0.05). There were no significant differences between the two groups in the mortality rate and the incidence rate of common complications in preterm infants including grade II-III necrotizing enterocolitis (P>0.05).@*CONCLUSIONS@#Implementation of the standardized nutrition protocol can facilitate the establishment of full enteral feeding, shorten the duration of parenteral nutrition, and reduce catheter-related bloodstream infection in very preterm/very low birth weight infants, without increasing the risk of necrotizing enterocolitis.

Changing trend of abdominal regional oxygen saturation in very/extremely low birth weight infants in the early postnatal stage: a prospective study / 中国当代儿科杂志

OBJECTIVES@#To study the changing trend of abdominal regional oxygen saturation (A-rSO@*METHODS@#The VLBW/ELBW infants who were admitted to the neonatal intensive care unit from September 2019 to May 2021 were enrolled as subjects. Near-infrared spectroscopy was used to monitor A-rSO@*RESULTS@#A total of 63 VLBW/ELBW infants were enrolled, with 30 infants in the <29 weeks group and 33 in the ≥29 weeks group.

Simultaneous determination of four components in Hedyotis diffusa oral solution by reversed-phase HPLC / 中国中药杂志

<p><b>OBJECTIVE</b>A new method for simultaneous determination of four methyl-3, 4-dihydroxybenzoate ( I ), P-coumaric acid (II), ferulaic acid (III) and E-6-O-P-coumaroyl scandoside methyl ester (IV) in Hedyotis diffusa oral solution by reversed-phase HPLC was developed.</p><p><b>METHOD</b>The separation was performed on a Diamonsil C18 column (4.6 mm x 250 mm, 5 microm) with gradient elution. A-acetonitrile, B-methonal-water-glacial acetic acid (5: 95: 0.25), 0-20 min, 1% -16% A; 2042 min, 16% A; 42-46 min, 16%-20%A; 46-65 min, 20% A. The UV detection was set at 265 nm; flow rate 1.0 mL x min(-1).</p><p><b>RESULT</b>There was good linearity between the peak area and concentration at the ranges of 2.1-105 (r = 0.999 8), 3.5-175 (r = 0.999 8), 1.72-86 (r = 0.999 9), 4.0-200 mg x L(-1) (r = 1.000 0) for I, II, III and IV respectively. The average recoveries of I, II, III and IV were 99.9%, 97.9%, 98.6% and 98.1%.</p><p><b>CONCLUSION</b>The method is rapid, simple and accurate, and it can be used for the evaluation of H. diffusa oral solution.</p>
