Comparison of the Effect of Nesting and Swaddling on Sleep Duration and Arousal Frequency among Preterm Neonates: A Randomized Clinical Trial

Nest positioning on motor development, sleep patterns, weight gain in preterm infants: systematic review

The aim was to evaluate the effects of Nest Positioning (NP) on motor development, sleep patterns, and weight gain in preterm newborns (PTNB) hospitalized in a neonatal intensive care unit (NICU). This study was constructed based on PRISMA guideline criteria. Systematic research was carried out in electronic databases: MEDLINE via PubMed, Web of Science, Scopus, and VHL-BIREME following the PICOS strategy. Studies with PTNB populations who were hospitalized in the NICU and received therapeutic NP as an intervention strategy in this population were included in this study. We sought outcomes related to sleep patterns, weight gain, and motor development. After selection, 12 studies were included in this systematic review, of which 5 (41.7%) evaluated motor development as their primary outcome, 6 (50%) sleep-wake cycle patterns, and 1 (8.3%), weight gain and, subsequently, hospital discharge. Qualitative results indicate that prolonged exposure to decubitus variations may favor PTNB hospitalized in NICUs acquiring flexor postures, stimulate their midline, and increase their total sleep time. Studies reported no adverse effects regarding the use of NP. Evidence suggests that NP benefits motor development and sleep pattern in PTNB hospitalized in NICUs. IMPACT: Nest positioning improves sleep quality in preterm newborns hospitalized in neonatal intensive care unit. Nest positioning improves motor development in preterm newborns hospitalized in neonatal intensive care unit. No evidence of nest positioning on weight gain was observed. Half of the included clinical studies showed good methodological quality. Nesting positioning is a secure and cost-effective method.

The Impact of Using Nesting Care on Heart Rate, Oxygen Saturation, and Pain Among Premature Neonates in Neonatal Intensive Care Units in Saudi Arabia: A Quasi-Experimental Study

BACKGROUND

Supportive positioning may mimic the intrauterine environment and enhance neonates' physiological and developmental outcomes. Limited research in Saudi Arabia examined the effect of supportive positioning aids (nesting) on infant outcomes in neonatal intensive care units (NICUs).

OBJECTIVE

This study compared nesting care to non-nesting care in the short-term outcomes of premature neonates (heart rate, oxygen saturation, and pain) in Saudi NICUs.

METHODS

A quasi-experimental design compared two groups of premature neonates from two NICUs regarding their heart rate, oxygen saturation, and pain level. Nesting was used in the first group, and not in the second group. Seventy premature neonates (35 per group) were recruited. An independent t-test was used to compare the two groups.

RESULTS

Heart rate was significantly lower in the nesting group than the non-nesting group at baseline and after procedures (136bpm and 139bpm vs 144bpm and 148bpm, P ≤ 0.05). The pain level was significantly lower in the nesting group than the non-nesting group at baseline and after procedures (3.7 and 3.8 vs 4.7 and 4.6, P ≤ 0.05). There was no significant difference between the two groups in oxygen saturation.

CONCLUSION

Nesting care supported premature neonates in the NICU. It helped stabilize the heart rate and pain. NICUs in Saudi Arabia would benefit from educating NICU nurses and informing NICU managers and policymakers of nesting care.

Practices for respecting the newborn's sleep-wake cycle: Interventional study in the neonatal intensive care unit

Objectives

Premature newborns are exposed to a great deal of over-stimulation, which can affect their cerebral development. For better sleep, certain practices should be recommended. The aim of this study was to evaluate the effect of a professional training program on the improvement of practices promoting respect for the newborn's sleep-wake cycle.

Materials and Methods

This was an interventional study with a longitudinal, single-group, and before-and-after design. The experimental design followed a three-stage time series: Eight months before, three months after, then eight months after intervention. It targeted a comprehensive sample of 66 professionals. It took place between October 2020 and March 2022 at the Neonatal Intensive Care Unit of the Hassan II University Hospital in Fez, Morocco. It was based on an observation grid and a self-administered questionnaire, validated and tested with a Cronbach's alpha reliability of 0.91.

Results

The light environment showed significant differences between the 1st and 3rd step (3.3% vs. 45.0%; P = 0.02; confidence interval [CI] = 13.644-10.456) for knowledge and (13.3% vs. 78.3%; P = 0.01; CI = 14.412-10.888) for practices; the noise environment showed a positive improvement between the 2nd and 3rd intervention (31.7% vs. 41.7%; P < 0.001; CI = 5.954-2.913) for knowledge and (65.0% vs. 73.3%; P < 0.001; CI = 3.597-1.236) for practices, with an average of (8.98 ± 0.30-28.15 ± 0.48; CI = 3.806-1.094) between the 1st and 3rd step. Practices surrounding sleep and wakefulness reported significant improvement between the three periods (14.35 ± 0.22 vs. 18.10 ± 0.35 vs. 19.90 ± 0.35; P P < 0.001; CI = 4.647-2.853) for sleep and (13.25 ± 0.48 vs. 22.27 ± 0.59; P < 0.001; CI = 10.563-7.471) for wakefulness with statistically significant correlations between knowledge and practices (0.426**) for sleep and (0.606**) for wakefulness.

Conclusion

The study demonstrated the positive impact of this sleep management and assessment program on the development of professional skills. Its implementation requires rigorous application of developmental support strategies for individualized care in neonatology.
