Bronchopulmonary dysplasia (BPD) is one of the most common chronic lung diseases in neonates especially in preterm infants. It is also the main reason leading to a poor prognosis. The prognosis of the neonates with BPD is unsatisfactory with current treatment strategies. Recent clinical trails have found that mesenchymal stem cell (MSC) transplantation might be effective and promising for treatment of BPD in neonates. This article outlines the characteristics of MSC and the potential mechanisms of MSC transplantation for BPD in vivo, and the safety and feasibility of MSC transplantation in BPD neonates, as well as the challenges in clinical trials on MSC transplantation for treatment of BPD.

There is a delicate balance between too little and too much supplemental oxygen exposure in premature infants. Since underuse and overuse of supplemental oxygen can harm premature infants, oxygen saturation levels must be monitored and kept at less than 95% to prevent reactive oxygen species-related diseases, such as retinopathy of prematurity and bronchopulmonary dysplasia. At the same time, desaturation below 80 to 85% must be avoided to prevent adverse consequences, such as cerebral palsy. It is still unclear what range of oxygen saturation is appropriate for premature infants; however, until the results of further studies are available, a reasonable target for pulse oxygen saturation (SpO2) is 90 to 93% with an intermittent review of the correlation between SpO2 and the partial pressure of arterial oxygen tension (PaO2). Because optimal oxygenation depends on individuals at the bedside making ongoing adjustments, each unit must define an optimal target range and set alarm limits according to their own equipment or conditions. All staff must be aware of these values and adjust the concentration of supplemental oxygen frequently.

Bronchopulmonary dysplasia (BPD) is a common chronic lung disease in preterm infants and seriously affects the quality of life of preterm infants. BPD is a life-threatening disease to preterm infants and may lead to serious sequelae including feeding difficulties, recurrent lower respiratory tract infection, airway hyperreactive diseases, growth retardation, and neurodevelopmental delay. In order to further standardize the follow-up management of preterm infants with BPD after discharge, based on related clinical evidence in China and overseas and practice experience, the Neonatal Evidence-Based Medicine Group, Committee of Neonatal Medicine, Cross-Strait Medical and Health Exchange Association, formulated this expert consensus from the aspects of the follow-up and management of respiratory diseases, growth and development, pulmonary hypertension, nerve dysplasia, metabolic bone disease, and vaccination of preterm infants with BPD after discharge.

Dramatic advances in neonatal medicine over recent decades have resulted in decreased mortality and morbidity rates for extremely low birth weight infants. However, the survival of these infants is associated with short- and long-term morbidity, including severe intraventricular hemorrhage, periventricular leukomalacia, nosocomial infection and necrotizing enterocolitis, bronchopulmonary dysplasia, retinopathy of prematurity and adverse long-term neurodevelopmental sequelae. This article reviewed the latest advances in the medical care for extremely low birth weight infants including survival rate, ethical issues and short- and long-term morbidity, domestically and abroad.

Bronchopulmonary dysplasia (BPD), a chronic lung disease affecting very premature infants, is a major cause of mortality and long-term morbidities despite of current progress in neonatal intensive care medicine. Though there has not been any effective treatment or preventive strategy for BPD, recent stem cell research seems to support the assumption that stem cell therapy could be a promising and novel therapeutic modality for attenuating BPD severity. This review summarizes the recent advances in stem cell research for treating BPD. In particular, we focused on the preclinical data about stem cell transplantation to improve the lung injury using animal models of neonatal BPD. These translational research provided the data related with the safety issue, optimal type of stem cells, optimal timing, route, and dose of cell transplantation, and potency marker of cells as a therapeutic agent. Those are essential subjects for the approval and clinical translation. In addition, the successful phase I clinical trial results of stem cell therapies for BPD are also discussed.

OBJECTIVETo study the efficacy of different preparations of budesonide combined with pulmonary surfactant (PS) in improving blood gas levels and preventing bronchopulmonary dysplasia (BPD) in preterm infants with neonatal respiratory distress syndrome (NRDS).

METHODSA total of 184 preterm infants who developed NRDS within 4 hours after birth were randomly administered with PS + continuous inhalation of budesonide aerosol (continuous aerosol group), PS+budesonide solution (solution group), PS + single inhalation of budesonide aerosol (single aerosol group), and PS alone, with 46 neonates in each group. The changes in arterial blood gas levels, rate of invasive mechanical ventilation after treatment, time of assisted ventilation, rate of repeated use of PS, and the incidence of BPD were compared between the four groups.

RESULTSOn the 2nd to 4th day after treatment, pH, PCO2, and oxygenation index (FiO2/PaO2) showed significant differences among the four groups, and the continuous aerosol group showed the most improvements of all indicators, followed by the solution group, single aerosol group, and PS alone group. The continuous aerosol group had a significantly shorter time of assisted ventilation than the other three groups (P<0.05). The solution group had a significantly shorter time of assisted ventilation than the single aerosol and PS alone groups (P<0.05). The rate of invasive mechanical ventilation after treatment, rate of repeated use of PS, and incidence of BPD showed significant differences among the four groups (P<0.05), and the continuous aerosol group had the lowest rates, followed by the solution group.

CONCLUSIONSA combination of PS and continuous inhalation of budesonide aerosol has a better efficacy in the treatment of NRDS than a combination of PS and budesonide solution. The difference in reducing the incidence of BDP between the two administration methods awaits further investigation with a larger sample size.

PURPOSE: We investigated the effects of restricted fluid in the first 7 days of life on the risk of bronchopulmonary dysplasia (BPD) or patent ductus arteriosus (PDA) in very low birth weight (VLBW) infants. METHODS: Eighty three VLBW infants who lived more than 28 days were selected. The amount of daily maintenance fluid was determined by calculation of insensible water loss (IWL) and urine output (UO). Seventy to 80 percent of calculated amount was given to the ventilated infants. Subjects were grouped into low (<25th%), moderate (25-75th%), and high (>75th%) fluid groups for the first 24 hours, 3 days and 7 days. Chi square tests analyzed proportions of subjects with or without morbidities across fluid groups. Multivariate logistic regression was used to analyze the effect of fluid intake on BPD or PDA, controlling for factors that are significantly associated with BPD or PDA by univariate analysis. RESULTS: Rates of BPD and PDA were not significantly associated with fluid groups on each time period. The result was the same after controlling for factors that are significantly associated with BPD or PDA by univariate analysis. For the first 3 and 7 days, fluid intakes were positively related with maximal weight loss, urine output and mechanical ventilation duration. CONCLUSION: In VLBW infants, when given based on needs reflected from IWL and UO versus intake, relatively low fluid intakes in the first week of life do not decrease the risk of BPD or PDA, and vice versa. We suggest that calculation of daily fluid based on IWL and UO is appropriate for VLBW infants.
