Abstract:

Background and purpose: Gavage feeding tubes increase the length of stay and reduce the growth process in neonates. The aim of this study was to determine the effect of non-nutritive sucking on weight gain and length of stay in neonates that required gavage feeding. Materials and methods: In a clinical trial, neonates were selected via convenience sampling and randomly assigned into an intervention group (n=37) or a control group (n=38). Data including demographic information, admission and discharge dates, and neonates’ weights were recorded. In the intervention group, non- nutritive sucking was performed by the mother's finger at the same time as the gavage feeding. Data analysis was performed in SPSS V20 applying independent t-test, Mann-Whitney, and Chi-square. Results: The mean weight at discharge was 90.73 g higher in the intervention group than the control group (P=0.121). The mean weight loss was found to be higher in control group than the intervention group (P= 0.818). The mean length of stay was 14.22± 8.32 days in intervention group and 14.61±7.34 in control group, indicating no significant differences between the two groups (P=0.830, statistical power=60%). Conclusion: Non-nutritive sucking had no significant positive effect on length of stay and weight gain in preterm infants. Further studies with larger sample size are suggested.

The Effect of Non-Nutritive Sucking on Weight Gain and Length of stay in Preterm Infants

Background: Preterm infants frequently experience oral feeding difficulties due to undeveloped oral- motor skills and lack of coordination between sucking, swallowing and breathing. Infants’ ability to orally consume all feedings while maintaining physiological stability and weight gain is necessary for their discharge. Aim: The effect of non-nutritive sucking on weight gain in preterm infants....

The Effect of Massage on Weight Gain of Low-Weight Hospitalized Infants: A Randomized Clinical Trial

Purpose: Low birth weight (LBW) is one of the most serious health problems in infants. Many studies indicate that LBW infants, who survive, may suffer from long- and short-term physical,mental, and social problems. This study aimed to determine the effect of massage therapy on weight gain of LBW neonates. Methods: This study was a randomized clinical trial. A total of 45 LBW neonates were rand...

مقایسه تأثیر دو روش مکیدن غیرمغذی و ماساژ دهانی بر زمان دستیابی به تغذیه دهانی مستقل و طول مدت بستری در نوزادان نارس بستری در NICU

  Background & Aim: Technology advancement has increased the survival rates of premature infants. Preterm newborns frequently experience oral feeding difficulties due to lack of coordination in sucking, swallowing and respiration. This may negatively affect attainment of independent oral feeding skill and leads to longer hospital stays. This study aimed to examine the effects of non-nutritive s...
