Impact of Evidence-Based Bundled Nutritional Care on Growth, Development and Nutritional Status in Low Birth Weight Preterm Infants.

OBJECTIVE

This study aimed to evaluate the effectiveness of evidence-based bundled nutritional care in low birth weight (LBW) preterm infants.

METHODS

The LBW preterm infants in the control group received routine nursing, while those in the observation group received evidence-based bundled nutritional interventions, including breast milk management, feeding management, nutritional monitoring, sucking function stimulation, nest-like intervention, touch intervention and discharge instructions based on routine nursing. All preterm infants were followed up for 6 months. Growth and development indices, nutritional and immune parameters, complication rates and parental satisfaction were compared between groups.

RESULTS

A total of 140 preterm infants were enrolled in the study, with 70 assigned to the observation group and 70 to the control group. At 6 months, the observation group showed greater gains in weight (0.62 ± 0.17 vs. 0.45 ± 0.13 g/kg d), length (9.28 ± 1.44 vs. 8.31 ± 1.17 cm/week), and head circumference (7.46 ± 0.97 vs. 6.19 ± 0.70 cm/week) compared with the control group (p < 0.05). After the intervention, levels of haemoglobin, prealbumin, albumin and total protein were significantly higher in the observation group compared with the control group (p < 0.05). Immunoglobulin A, M and G concentrations also increased more markedly in this group (p < 0.05). The incidence of complications was lower in the observation group (7.14% vs. 18.57%, p < 0.05), while parental satisfaction was higher (95.71% vs. 84.29%, p < 0.05) compared with the control group.

CONCLUSION

Evidence-based bundled nutritional care yields favourable outcomes in LBW preterm infants by promoting physical growth, enhancing nutritional and immune status, reducing complications and improving family satisfaction.
