Abstract:
Objective To evaluate the effectiveness of domestic exogenous pulmonary surfactant (EPS)-Calsurf in treating full-term neonatal respiratory distress syndrome (RDS).Methods (1) From January 2011 to June 2012,154 full-term neonates with RDS were divided into Calsurf group (74 cases) and Curosurf group (80 cases),comparing differences in changes of arterial blood gas,the length of hospital stay,hospitalization expenses,duration of mechanical ventilation,inspired oxygen time,the incidences of complications and repeated EPS use rates between two groups.(2) In order to compare the effectiveness of different doses of Calsurf in treating full-term neonatal RDS,from July 2012 to March 2013,80 RDS patients who received Calsurf were divided into mild-moderate group (grade Ⅱ ～ Ⅲ on chest X-ray,50 cases) and severe group (grade Ⅳ on chest X-ray,30 cases).Furthermore,each group was divided into two subgroups,which were low-dosage(per-time 30 ～40 mg/kg) and high-dosage group (per-time 30 ～40 mg/kg).Results (1) Before administrating Calsurf and after administrating it at 0.5 h and 6 h,the pH,PaCO2 and PaO2 of RDS patients were no significant difference in two groups (P ＞ 0.05).(2) There were no significant difference between the duration of mechanical ventilation,inspired oxygen time,length of hospital stay in two groups (P ＞ 0.05).But the hospitalization expenses in Calsurf and Curosurf groups were 28.778 versus 31.827 thousand yuan,respectively,with the average reduction of 9.6％ in Calsurf group (P ＜ 0.05).(3) There were no significant difference between the morbidities and mortalities of multiple organ failure,persistent pulmonary hypertension,acute renal failure and pneumothorax in two groups (P ＞ 0.05).(4) In mild-moderate grade RDS patients,the low-dosage or high-dosage of Calsurf had similar effectiveness in improving bloog gas (P ＞ 0.05),the repeated Calsurf use rates of both subgroups were 16.0％ (4/25) and 20.0％ (5/25) (P ＞ 0.05).While in severe RDS patients,high-dosage Calsurf got a better effectiveness in improving bloog gas than low-dosage Calsurf(P ＜ 0.05).Meanwhile,the repeated Calsurf use rates of the low-dosage and high-dosage subgroups were 20.0％ (3/15) and 33.3％ (5/15),with a 40％ reduction in high-dosage subgroup.Conclusion (1) Both Calsurf and Curosurf can significantly improve the conditions of hypoxemia and hypercapnia,moreover,the length of hospital stay and duration of mechanical ventilation of both groups are similar,with less hospitalization expense in Calsurf group.(2) Both low and high-dosage Calsurf have similar curative effect on mild-moderate RDS,but for severe RDS,high-dosage Calsurf works better,reducing the repeated EPS use rate to some extent.
