Résumé
Objective To study the effect on using L‐carnitine in early intravenous nutrition of premature infants which aims to improve fat metabolism ,promote growth and development .Methods Ninety cases of premature infants were divided into the con‐trol group and observation group .All patients received conventional treatments such as keeping warm ,giving intravenous nutrition , etc .And those in the observation group received L‐carnitine beside routine care ,then compared efficacy of 2 groups .Results Total protein ,albumin ,hemoglobin ,body weight growth of the observation group are better than those of the control group(P<0 .05) . The observation group was superior to the control group in not only reducing incidence rate of preterm children PNAC but also in improving the treatment effect .Conclusion Using L‐carnitine in early intravenous nutrition of premature infants could improve fat metabolism ,promote growth effect ,reduce the incidence rate of cholestasis with few adverse effects .
Résumé
Objective To investigate the diagnostic significance of ultrasonic bone mineral density measurement in infant rickets.Methods A total of 120 cases of rickets in children and 120 healthy infants were divided into three groups according to age,＜ 1 year group,1-2 years group,＞ 2 years group,who were subjected to determination of ultrasonic bone mineral density.The Z value and percentage of bone mineral density via ultrasound detection among different groups were compared.Results There were statistically significant differences in Z value and the percentage between each age group of infant rickets and healthy children according to bone mineral density via ultrasound detection (P ＜ 0.05).No significant differences in Z value and the percentage between each age group of male and female children of infant rickets through ultrasound detection (P ＞0.05).Conclusions The ultrasonic bone mineral density detection in the diagnosis of infant rickets had advantages of sensitivity,specificity,convenient detection,painless,noninvasive and easy popularization,which plays an active role in the early diagnosis and treatment of rickets,itis worth in clinical application.
