Neonates are an extremely vulnerable patient population, with 6% to 9% admitted to the neonatal intensive care unit (NICU) following birth. Neonates admitted to the NICU will undergo multiple painful procedures per day throughout their stay. There is increasing evidence that frequent and repetitive exposure to painful stimuli is associated with poorer outcomes later in life. To date, a wide variety of pain control mechanisms have been developed and implemented to address procedural pain in neonates. This review focused on non-opioid analgesics, specifically non-steroidal anti-inflammatory drugs (NSAIDs) and N-methyl-D-aspartate (NMDA) receptor antagonists, which alleviate pain through inhibiting cellular pathways to achieve analgesia. The analgesics considered in this review show potential for pain relief in clinical practice; however, an evidence summation compiling the individual drugs they comprise and outlining the benefits and harms of their administration is lacking. We therefore sought to summarize the evidence on the level of pain experienced by neonates both during and following procedures; relevant drug-related adverse events, namely episodes of apnea, desaturation, bradycardia, and hypotension; and the effects of combinations of drugs. As the field of neonatal procedural pain management is constantly evolving, this review aimed to ascertain the scope of non-opioid analgesics for neonatal procedural pain to provide an overview of the options available to better inform evidence-based clinical practice. OBJECTIVES: To determine the effects of non-opioid analgesics in neonates (term or preterm) exposed to procedural pain compared to placebo or no drug, non-pharmacological intervention, other analgesics, or different routes of administration. ⋯ We included two RCTs involving a total of 269 neonates conducted in Nigeria and India. NMDA receptor antagonists versus no treatment, placebo, oral sweet solution, or non-pharmacological intervention One RCT evaluated using oral ketamine (10 mg/kg body weight) versus sugar syrup (66.7% w/w at 1 mL/kg body weight) for neonatal circumcision. The evidence is very uncertain about the effect of ketamine on pain score during the procedure, assessed with the Neonatal Infant Pain Scale (NIPS), compared with placebo (mean difference (MD) -0.95, 95% confidence interval (CI) -1.32 to -0.58; 1 RCT; 145 participants; very low-certainty evidence). No other outcomes of interest were reported on. Head-to-head comparison of different analgesics One RCT evaluated using intravenous fentanyl versus intravenous ketamine during laser photocoagulation for retinopathy of prematurity. Neonates receiving ketamine followed an initial regimen (0.5 mg/kg bolus 1 minute before procedure) or a revised regimen (additional intermittent bolus doses of 0.5 mg/kg every 10 minutes up to a maximum of 2 mg/kg), while those receiving fentanyl followed either an initial regimen (2 μg/kg over 5 minutes, 15 minutes before the procedure, followed by 1 μg/kg/hour as a continuous infusion) or a revised regimen (titration of 0.5 μg/kg/hour every 15 minutes to a maximum of 3 μg/kg/hour). The evidence is very uncertain about the effect of ketamine compared with fentanyl on pain score assessed with the Premature Infant Pain Profile-Revised (PIPP-R) scores during the procedure (MD 0.98, 95% CI 0.75 to 1.20; 1 RCT; 124 participants; very low-certainty evidence); on episodes of apnea occurring during the procedure (risk ratio (RR) 0.31, 95% CI 0.08 to 1.18; risk difference (RD) -0.09, 95% CI -0.19 to 0.00; 1 study; 124 infants; very low-certainty evidence); and on hypotension requiring medical therapy occurring during the procedure (RR 5.53, 95% CI 0.27 to 112.30; RD 0.03, 95% CI -0.03 to 0.10; 1 study; 124 infants; very low-certainty evidence). The included study did not report pain score assessed up to 10 minutes after the procedure or episodes of bradycardia occurring during the procedure. We did not identify any studies comparing NSAIDs versus no treatment, placebo, oral sweet solution, or non-pharmacological intervention or different routes of administration of the same analgesics. We identified three studies awaiting classification. AUTHORS' CONCLUSIONS: The two small included studies comparing ketamine versus either placebo or fentanyl, with very low-certainty evidence, rendered us unable to draw meaningful conclusions. The evidence is very uncertain about the effect of ketamine on pain score during the procedure compared with placebo or fentanyl. We found no evidence on NSAIDs or studies comparing different routes of administration. Future research should prioritize large studies evaluating non-opioid analgesics in this population. As the studies included in this review suggest potential positive effects of ketamine administration, studies evaluating ketamine are of interest. Furthermore, as we identified no studies on NSAIDs, which are widely used in older infants, or comparing different routes of administration, such studies should be a priority going forward.

ReviewNebulised hypertonic saline solution for acute bronchiolitis in infants.
Airway oedema (swelling) and mucus plugging are the principal pathological features in infants with acute viral bronchiolitis. Nebulised hypertonic saline solution (≥ 3%) may reduce these pathological changes and decrease airway obstruction. This is an update of a review first published in 2008, and updated in 2010, 2013, and 2017. ⋯ Nebulised hypertonic saline may modestly reduce length of stay amongst infants hospitalised with acute bronchiolitis and may slightly improve clinical severity score. Treatment with nebulised hypertonic saline may also reduce the risk of hospitalisation amongst outpatients and ED patients. Nebulised hypertonic saline seems to be a safe treatment in infants with bronchiolitis with only minor and spontaneously resolved adverse events, especially when administered in conjunction with a bronchodilator. The certainty of the evidence was low to very low for all outcomes, mainly due to inconsistency and risk of bias.

ReviewAnti-vascular endothelial growth factor for neovascular glaucoma.
Neovascular glaucoma (NVG) is a potentially blinding, secondary glaucoma. It is caused by the formation of abnormal new blood vessels, which prevent normal drainage of aqueous from the anterior segment of the eye. Anti-vascular endothelial growth factor (anti-VEGF) medications are specific inhibitors of the primary mediators of neovascularization. Studies have reported the effectiveness of anti-VEGF medications for the control of intraocular pressure (IOP) in NVG. ⋯ Anti-VEGFs as an adjunct to conventional treatment could help reduce IOP in NVG in the short term (four to six weeks), but there is no evidence that this is likely in the longer term. Currently available evidence regarding the short- and long-term effectiveness and safety of anti-VEGFs in achieving control of IOP, visual acuity, and complete regression of new iris vessels in NVG is insufficient. More research is needed to investigate the effect of these medications compared with, or in addition to, conventional surgical or medical treatment in achieving these outcomes in NVG.

ReviewChest physiotherapy for acute bronchiolitis in paediatric patients between 0 and 24 months old.
Acute bronchiolitis is the leading cause of medical emergencies during winter months in infants younger than 24 months old. Chest physiotherapy is sometimes used to assist infants in the clearance of secretions in order to decrease ventilatory effort. This is an update of a Cochrane Review first published in 2005 and updated in 2006, 2012, and 2016. ⋯ We found low-certainty evidence that passive slow expiratory technique may result in a mild to moderate improvement in bronchiolitis severity when compared to control. This evidence comes mostly from infants with moderately acute bronchiolitis treated in hospital. The evidence was limited with regard to infants with severe bronchiolitis and those with moderately severe bronchiolitis treated in ambulatory settings. We found high-certainty evidence that conventional techniques and forced expiratory techniques result in no difference in bronchiolitis severity or any other outcome. We found high-certainty evidence that forced expiratory techniques in infants with severe bronchiolitis do not improve their health status and can lead to severe adverse effects. Currently, the evidence regarding new physiotherapy techniques such as RRT or instrumental physiotherapy is scarce, and further trials are needed to determine their effects and potential for use in infants with moderate bronchiolitis, as well as the potential additional effect of RRT when combined with slow passive expiratory techniques. Finally, the effectiveness of combining chest physiotherapy with hypertonic saline should also be investigated.

Review Meta AnalysisMammography in combination with breast ultrasonography versus mammography for breast cancer screening in women at average risk.
Screening mammography can detect breast cancer at an early stage. Supporters of adding ultrasonography to the screening regimen consider it a safe and inexpensive approach to reduce false-negative rates during screening. However, those opposed to it argue that performing supplemental ultrasonography will also increase the rate of false-positive findings and can lead to unnecessary biopsies and treatments. ⋯ Based on one study in women at average risk of breast cancer, ultrasonography in addition to mammography leads to more screening-detected breast cancer cases. For women with dense breasts, cohort studies more in line with real-life clinical practice confirmed this finding, whilst cohort studies for women with non-dense breasts showed no statistically significant difference between the two screening interventions. However, the number of false-positive results and biopsy rates were higher in women receiving additional ultrasonography for breast cancer screening. None of the included studies analysed whether the higher number of screen-detected cancers in the intervention group resulted in a lower mortality rate compared to mammography alone. Randomised controlled trials or prospective cohort studies with a longer observation period are needed to assess the effects of the two screening interventions on morbidity and mortality.
