ObjectiveTo systematically review the protective effect of serum maternal respiratory syncytial virus (RSV) antibodies on infants with RSV infection. MethodsPubMed, EMbase, The Cochrane Library, CBM, CNKI and WanFang Data databases were electronically searched to collect observational studies on the correlation between serum maternal RSV antibodies and infants with RSV infection from inception to July 18, 2021. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies, then, qualitative analysis was performed. ResultsA total of 19 studies were included, and 60% of those studies suggested that a higher level of maternal antibodies could prevent RSV infection. However, the remaining 40% of them showed that there was no significant difference in the level of RSV maternal antibodies between the infected group and the non-infected group. Further more, in the studies of the correlation between maternal antibody level and disease severity after RSV infection, 55% of those showed that maternal antibody level was negatively correlated with disease severity. ConclusionThe protective effect of serum maternal RSV antibodies on infants reported in different studies varies. Whether it can prevent RSV infection and affect the severity of RSV infected children still needs to be explored.

Objective To evaluate the effect of exogenous pulmonary surfactant(PS) replacement therapy for infants who suffered pulmonary injury after cardiopulmonary bypass. Methods Seven infants (age 0.49±0 82 year, weight 4.87±2.18kg) who depended on respiratory mechanical support with clinical and radiological evidence of pulmonary surfactant sufficiency were enrolled in the study. Oxygen index(OI), artery oxygen saturation(SaO 2) and artery bicarbonate pressure(PaCO 2) were measured at 4, 6, 12, 24, 48, and 72 h after the first application of PS(100mg/kg). At the meantime, maximum spontaneous respiratory tidal volume, chest X ray changes and ventilator time were recorded. Results Compared to the baseline values, OI and SaO 2 increased significantly 4 h after PS therapy, with a maximal increase slope (34.7%, 6.6%) after 24 h. While PaCO 2 decreased significantly 4 h after PS therapy, with a lowest decrease slope (22.8%) after 6 h ( P lt;0.05, 0.01). Spontaneous tidal volume and chest X ray si...更多gn were improved in all infants. The success rate of extubation was 85 7%. Conclusion Exogenous PS replacement therapy could improve pulmonary function for postoperative infants, and highly decrease the ventilator time.
Objective To investigate the effect of surgical treatment on ventricular septal defect (VSD) in infants under 6kg weight, including the operative indication, surgical techniques and perioperative therapy. Methods All clinical data of 148 consecutive infants under 6kg weight with VSD were collected and studied retrospectively. The infants, age was 1-13(mean 5.3) months with the body weight of 3.5-6.0 (mean 5.3) kg. VSD was perimembranous in 105 cases, subpulmonary in 25, muscular inlet tract in 8, muscular outlet tract 9, and muscular trabecular in 1 case. Other associated cardiac abnormalities included atrial septal defect in 39, patent ducts arteriosus in 17, insufficiency of mitral valve in 9 and moderate to severe pulmonary hypertension in 52. The operations were performed under cardiopulmonary bypass at moderate to low flow, moderate hypothermia and cold crystalloid cardioplegia. Patch repair was used in 85, direct sutures in 63 and 23 cases repaired with partial sternal incision and beating heart. Results The hospital mortality was 4. 1% (6/148), the causes of death were severe pulmonary hypertention in 2, aortic arch interruption in 2, severe malnutrition in 1 and poor result of mitral valvuloplasty in 1. Other major operative complications included residual shunts (1- 2mm) in 2, and Ⅲ° A-V block in 2, who recoveried 5 days after the operation. The hospital stay was 6 15 (mean 8) days. Follow-up was complete in all 142 survived cases for 4 months-6 years. Two residual shunts healed in first year after the cardiac operation, others recovery smoothly, and are developing well. Conclusion With the improvement of the surgical techniques, the surgical treatment for VSD in infants with low weight is safe and effective, and it is also essential to further improve the effects of surgical treatment in VSD associated with complex abnormalities.
In order to guide diagnosis and treatment in children with sleep disordered breathing aged 1 to 23 months, the European Respiratory Society(ERS) summarized the evidence and released the European Respiratory Society statement based on clinical experience in 2016. This article aims to interpret the ERS statement. Children with apparent upper airway obstruction during wakefulness and those with SDB symptoms and complex conditions requires treatment. Adenotonsillectomy and continuous positive airway pressure are the most frequently used treatment measures along with interventions targeting specific conditions. Obstructive SDB in children aged 1 to 23 months is a multifactorial disorder that requires objective assessment and treatment of all underlying abnormalities.
Abstract: Objective To identify the risk factors for shortterm adverse events in infants with congenital heart diseases receiving open heart surgical correction with cardiopulmonary bypass (CPB), in order to improve the outcome by adopting appropriate treatment measures. Methods We retrospectively analyzed the clinical data of 98 consecutive children with congenital heart diseases who underwent surgical correction with CPB in Beijing Fu Wai Hospital from November 2009 to December 2009. The patients were divided into two groups according to the postoperative complications. Among the patients without complications(n=40): there were 24 males and 16 females with an age of 7.60±0.40 months and a weight of 7.80±0.30 kg. In the patients with complications (n=58): there were 42 males and 16 females with an age of 6.20±0.40 months and a weight of 6.70±0.20 kg. In both groups, perioperative data were recorded, including preoperative fast blood glucose, creatinine, time of aortic crossclamp, modified or zerobalanced ultrafiltration, postoperative glucose level, concentration of lactate, notrope score and complications. Risk stratification was performed by Risk Adjusted Classification for Congenital Heart Surgery (RACHS-1). Univariate analysis and logistic regression analysis were used to identify the risk factors for shortterm adverse events. Results One patient(1.02%) died of circulatory failure during the perioperative period. Thirtyseven patients [CM(159mm]were supported by at least 2 vasoactive drugs for more than 48hours,29 by mechanical ventilation for more than 24 hours, 5 needed reintubation, 1 experienced tracheotomy, 31 suffered from noscomial infection, 4 had wound infection, 3 developed renal failure, and 1 developed hepatic dysfunction. By logistic regression analysis, age (OR=0.750, P=0.012), percutaneous oxygen saturation (OR=0.840,P=0.005), aortic crossclamp time (OR=1.040, P=0.008), postoperative glucose level (patients with a mean glucose level lower or equal to 8.33 mmol/L had a probability of developing adverse outcomes five times higher; OR=5.051, P=0.011) were found to be the risk factors for shortterm adverse outcomes. Conclusion Age, percutaneous oxygen saturation and aortic crossclamp time are associated with the shortterm adverse outcome of infants undergoing congenital heart disease correction with CPB. The present results do not support perioperative hyperglycemia as a risk factor for adverse outcome.
