Background:
Feeding intolerance in premature infants is one of the main causes of their long-term hospitalization in NICUs. Massage therapy is a cost-effective intervention that has a positive impact on the health of infants and their parents. This systematic review investigates the effect of massage on feeding intolerance in preterm infants.
Methods:
A search was carried out in English databases including Medline (via PubMed), Scopus, Cochrane Library, Google Scholar, Embase (via Ovid) and Persian databases including SID and Magiran for articles published until November 2019 with language restrictions (English or Persian) but no time restrictions. The risk of bias in the studies was assessed using the Cochrane guidelines. The results of the meta-analysis were reported as mean difference, and the heterogeneity of the studies was evaluated using I2. GRADE approach was used to assess the quality of the evidence.
Results:
Of the 528 reviewed articles, eight were eligible for this study and finally six studies were included in the meta-analysis. According to the meta-analysis conducted on 128 preterm infants, the mean gastric residual volume (MD = - 2.11; 95% CI: - 2.76 to - 1.45, P < 0.00001) and mean frequency of vomiting (MD = - 0.84; 95% CI: - 1.37 to - 0.31; P = 0.002) were significantly lower in the massage therapy group compared to the control group. The mean abdominal circumference (MD = - 1.51; 95% CI: - 4.86 to 1.84; P = 0.38) and mean gastric residual number (MD = - 0.05; 95% CI: - 0.34 to 0.24; P = 0.74) were lower in the massage therapy group compared to the control group, although not in a statistically significant manner.
Conclusion:
Massage therapy significantly reduces the gastric residual volume and vomiting in preterm infants. Given the limited number of reviewed studies, the small number of neonates examined, and the short intervention periods, it is recommended that clinical trial be conducted with accurate methodology, longer interventions and larger sample sizes to ensure the effect of massage on feeding intolerance in these infants.
