Review Meta AnalysisCycled light in the intensive care unit for preterm and low birth weight infants.
Preterm and low birth weight infants are at an early stage of development, and do not receive adequate maternal circadian signals. They are often cared for over prolonged periods of hospitalisation in neonatal intensive care units (NICU), where environmental circadian stimuli are lacking. Exposure to artificial light-dark cycles may stimulate the development of the circadian system and improve clinical outcomes. However, it remains uncertain whether cycled light (CL) is preferable to near darkness (ND) or continuous bright light (CBL) in fostering development and maturation, and reducing adverse neonatal health outcomes. This is an update of an earlier Cochrane review, last published in 2016. ⋯ Despite identifying 20 studies, we remain uncertain about the effect of CL compared to ND or CBL on all outcomes of interest in this review. In addition, a few critical outcomes were not reported by any of the included studies. The evidence remains uncertain about whether CL is the right choice in the NICU. The physician should always weigh the benefits and risks, based on the effects of the different options in the specific setting.

Review Meta AnalysisAcupuncture for hypoxic ischemic encephalopathy in neonates.
Peripartum asphyxia affects three to five per 1000 live births, with moderate or severe hypoxic ischemic encephalopathy (HIE) occurring in 0.5 to 1 per 1000 live births, and is associated with high mortality and morbidity. Therapeutic hypothermia is an effective treatment, but alternative therapies such as acupuncture are also used. ⋯ There is limited availability of studies addressing this specific population. The included studies did not assess mortality, long-term neurodevelopmental outcomes, or adverse effects of acupuncture. We are unable to draw any conclusions about the benefits and harms of acupuncture for HIE in neonates. In light of the current limitations, clinicians are urged to approach the use of acupuncture in neonates with HIE cautiously, as there is no evidence to support its routine application. The available trials assessed surrogate outcomes that have a relatively small impact on newborns, and failed to report important outcomes such as mortality and long-term neurodevelopmental outcomes. Other available trials were performed on older infants who had experienced neonatal HIE. Given the lack of available evidence, well-designed randomized controlled trials with relevant outcomes such as mortality and neurodevelopmental outcomes are essential to evaluate the efficacy and safety of acupuncture for HIE in neonates.

Review Meta AnalysisFluid restriction for treatment of symptomatic patent ductus arteriosus in preterm infants.
The ductus arteriosus is a blood vessel connecting the main pulmonary artery and the proximal descending aorta. After birth, the ductus arteriosus usually closes completely. However, sometimes it remains patent in the neonate, which is called patent ductus arteriosus (PDA). If a PDA is clinically symptomatic, it can lead to overcirculation in the lungs, and reduced perfusion to the gut and kidneys. Most clinical practice guidelines suggest fluid restriction as a conservative management strategy for the treatment of symptomatic PDA. Restricting fluid has been shown to reduce the incidence of PDA in older preterm infants. However, aggressive restriction of fluids may affect systemic blood flow in extremely preterm infants. Given the potential adverse effects, it is important to systematically evaluate the evidence on the use of fluid restriction to treat symptomatic PDA to inform clinical decisions. ⋯ No evidence from RCTs is currently available to evaluate the benefits and harms of fluid restriction for the treatment of symptomatic patent ductus arteriosus in preterm infants. We identified no ongoing studies. Evidence from sufficiently powered RCTs evaluating fluid restriction for treatment of symptomatic PDA in preterm neonates is needed to inform clinical decisions.
