Background A domestic surfactant preparation has been used in China for a number of years. However, as for other surfactant preparations, there is debate among neonatologists regarding the optimal dose, mode of administration, and the best time of intervention. Objective To evaluate whether prophylactic administration of surfactant is superior to early treatment in preterm infants < 32 weeks with a high risk of respiratory distress syndrome (RDS). Methods We prospectively compared small premature infants (< 32 weeks) receiving 70 mg/kg bovine surfactant within 30 minutes after birth (prophylactic group, N = 116) with infants who received surfactant therapy for established RDS (early treatment group, N = 91). The primary outcome assessed was the incidence of RDS. The secondary outcomes assessed were severity of RDS, mortality, and bronchopulmonary dysplasia morbidity. Results Compared with the early treatment group, the prophylactic group had a significantly better PaO2 (at 1 hour, 4 hours, and 12 hours postdose, respectively), better a/APO2 (at 1 hour, 4 hours, 12 hours, and 24 hours postdose, respectively), lower PaCO2 (at 1 hour postdose), and a significantly decreased need for mean airway pressure (MAP) and FiO2 on ventilation (p < 0.05). The prophylactic group had shorter durations for mechanical ventilation and supplemental oxygen compared with the early treatment group (p < 0.01 and p < 0.05, respectively). The incidence of RDS was comparable between the groups; however, the prophylactic group had a significantly lower incidence of severe RDS and significantly lower rate of repeated doses of surfactant than the early treatment group (p < 0.05). The incidences of bronchopulmonary dysplasia and patent ductus arteriosus were also lower in the prophylactic group than the early treatment group (p < 0.05). The two groups were comparable in mortality rate. Conclusion In preterm infants under 32 weeks' gestation, prophylactic use of a domestic surfactant preparation is better than early surfactant treatment in improving pulmonary status and in decreasing the incidence of severe RDS and duration on mechanical ventilation. © 2016, Taiwan Pediatric Association.

Aim: To investigate the clinical features of airway malacia in children. Material and methods: A comprehensive analysis was done on information of 459 young patients with airway malacia. Results: Number of children with tracheomalacia, tracheobronchomalacia, and bronchomalacia was 7 (1.5%), 17 (3.7%), and 435 (94.8%), respectively. Incidence of bronchomalacia in left lung was 11.0% (n=48), while that of right lung was 53.3% (n=232). Meanwhile, bronchomalacia of both lungs were noticed in 155 children (35.6%). With regards to the extent of malacia, number of children with slight, moderate and severe malacia was 226, 195, and 38, respectively. All the children enrolled in this study were diagnosed with pulmonary infection, among which 376 were diagnosed with ordinary pneumonia, 83 were diagnosed with severe pneumonia. 227 children showed a disease course of less than 1 month, while 201 children reported a disease course of 1∼3 months, and 31 children reported a disease course of more than 3 months. Statistical difference was noticed in the disease condition of respiratory tract infection of patients with various malacia extent (P < 0.05). Re-check of fiberoptic bronchoscopy was performed in 19 patients, among which 14 patients (73.7%) showed improvement compared with the previous conditions. Conclusion: Airway malacia has been frequently noticed in male children aged ≤ 2 years old. Patients with severe airway malacia were apt to develop severe pneumonia compared with those with slight or moderate malacia. Improvements or even elimination of malacia were noticed with the aging of the children and the anti-infection therapy. © 2014, International Journal of Clinical and Experimental Medicine.
