目的观察肺表面活性物质(PS)在治疗足月儿及近足月儿呼吸窘迫综合征的疗效。方法研究新生儿科的94例足月及近足月呼吸窘迫综合征患儿,其中48例未使用PS的新生儿设为对照组,46例应用PS的新生儿设为观察组。观察:12组治疗方式的不同。2 2组使用鼻塞持续气道正压通气(CPAP)治疗及呼吸机治疗参数、肺氧合功能的比较。3两组住院天数、用氧天数、住院费用的比较。结果 1观察组减少了使用鼻塞CPAP及呼吸机机械通气的病例。2观察组在使用鼻塞CPAP及呼吸机治疗参数PIP、MAP、Fi O2及上机时间均明显低于对照组,观察组Pa O2/Fi O2氧合功能较对照组明显改善。3观察组用氧天数和住院天数均明显短于对照组。2组住院费用无统计学差异。结论 PS在足月儿及近足月儿呼吸窘迫综合征替代治疗中能改善新生儿的氧合功能,降低呼吸机参数,缩短用氧时间、机械通气时间和住院天数,未明显增加经济费用。
Objective To observe the efficacy of pulmonary surfactant (PS) in the treatment of respiratory distress syndrome in term infants and infants. Methods A total of 94 neonates with full-term and near-term respiratory distress syndrome were enrolled in this study. Forty-eight newborns without PS were enrolled as control group, and 46 newborns with PS as observation group. Observation: 12 groups of different treatment methods. 22 patients were treated with nasal continuous positive airway pressure (CPAP) and ventilator treatment parameters, pulmonary oxygenation function comparison. 3 two days of hospitalization, the number of days with oxygen, hospital costs comparison. Results 1 The observation group reduced the use of nasal CPAP and ventilator mechanical ventilation cases. 2 The observation group was significantly lower than the control group in the use of nasal CPAP and ventilator treatment parameters PIP, MAP, Fi O2 and on-machine time, the observation group Pa O2 / Fi O2 oxygenation function significantly improved compared with the control group. 3 The observation group with oxygen days and hospital days were significantly shorter than the control group. There was no significant difference between the two groups in hospitalization costs. Conclusion PS can improve neonatal oxygenation, reduce ventilatory parameters, shorten the duration of oxygen use, duration of mechanical ventilation and days of hospitalization in full-term and near-term neonatal respiratory distress syndrome replacement therapy without any significant increase in economic costs.
