Oral stimulation combined with non-nutritional sucking to improve feeding in preterm infants: a meta-analysis / 中国新生儿科杂志

Objective:To systematically evaluate the effects of oral stimulation combined with non-nutritional sucking on premature infants feeding.Methods:From the establishment of the databases to December 14, 2020, PubMed, Embase, Cochrane Library and SinoMed, CNKI, Wanfang databases were searched for randomized controlled trials (RCT) on oral stimulation combined with non-nutritive sucking in preterm infants. The gestational age (GA) of the infants was 26~37 w.The control group received routine nursing or sham treatment and the intervention group received oral stimulation and non-nutritional sucking on the basis of routine nursing. The intervention strategy included infant oral motor intervention and oral sensorimotor intervention. The literature were reviewed and the quality of RCTs evaluated. RevMan 5.3 software was used for meta-analysis.Results:A total of 20 RCTs were included, including 1 316 premature infants (GA 26~36 w). Compared with the control group, the intervention group had significantly shorter duration of hospital stay ( WMD=-3.45, 95% CI -4.41~-2.50, P<0.001). Significant differences existed in the corrected GA of discharge ( WMD=-0.68, 95% CI -1.10~-0.26, P=0.001), the age of total oral feeding(TOF) ( WMD=-5.22, 95% CI -9.04~-1.40, P=0.007), corrected GA of TOF ( WMD=-1.02, 95% CI -1.40~-0.64, P<0.001) and the body weight on TOF day ( WMD=-59.75, 95% CI -114.55~-4.95, P=0.030). Conclusions:Oral stimulation combined with non-nutritive sucking can accelerate TOF and shorten hospital stay in premature infants. The procedure should be standardized and promoted as routine and standard care for premature infants.

Progress on the application of inhaled nitric oxide in preterm infants / 中国小儿急救医学

Nitric oxide is an endothelium-derived relaxing factor, which has the effect of dilating pulmonary vessels and reducing pulmonary artery pressure.Currently, inhaled nitric oxide has been widely used in the treatment of persistent pulmonary hypertension in term infants and late preterm infants, but its use in the field of preterm infants is still controversial.In recent years, there have been more and more studies on inhaled nitric oxide in premature infants.This review summarized the relevant studies at home and abroad in recent years, discussed the indications of inhaled nitric oxide in premature infants, and introduced the potential adverse reactions, in order to provide guidance for clinical work.
