肺表面活性物质联合经鼻持续气道正压通气治疗对新生儿呼吸窘迫综合征患儿血气指标及预后的影响

Effect of pulmonary surfactant combined with nasal continuous positive airway pressure on blood gas index and prognosis in neonates with respiratory distress syndrome

目的探讨肺表面活性物质(PS)联合经鼻持续气道正压通气(nCPAP)治疗新生儿呼吸窘迫综合征(NRDS)的临床效果和安全性。方法选取2018年8月至2020年10月于广东省廉江市人民医院治疗的82例NRDS患儿,按随机数字表法分为两组,每组各41例。对照组予以nCPAP治疗,观察组加用PS治疗。比较两组血气指标、临床相关指标和并发症发生状况。结果治疗后,观察组患儿血氧分压(PaO2)、血氧饱和度(SaO2)、pH值分别为(88.96±6.25)mmHg、(92.58±3.15)%、(7.68±1.25),高于对照组的(81.45±6.12)mmHg、(88.69±4.58)%、(7.06±1.17),观察组患儿二氧化碳分压(PaCO2)为(31.12±4.03)mmHg,低于对照组的(36.45±4.18)mmHg,差异有统计学意义(P<0.05);观察组患儿氧疗时间、nCPAP时间和住院时间为(87.89±7.85)h、(95.14±9.46)h、(19.58±2.36)d,短于对照组的(115.46±9.37)h、(130.58±20.76)h、(24.55±4.12)d,差异有统计学意义(P<0.05);观察组患儿并发症发生率为4.88%,较对照组的19.51%低,差异有统计学意义(P<0.05)。结论PS联合nCPAP可增强NRDS患儿治疗效果,改善患儿动脉血气指标,纠正机体缺氧症状,缩短住院时间,减少并发症发生。

Objective To explore the clinical efficacy and safety of pulmonary surfactant(PS)combined with nasal continuous positive airway pressure(nCPAP)in the treatment of neonatal respiratory distress syndrome(NRDS).Methods A total of 82 children with NRDS treated in Lianjiang People's Hospital,Guangdong from August 2018 to October 2020 were selected and randomly divided into two groups,with 41 cases in each group.The control group was treated with nCPAP,while the observation group was treated with nCPAP combined with PS.The blood gas indexes,clinical related indexes and complications of the two groups were compared.Results After treatment,the partial pressure of blood oxygen(PaO2),saturation of blood oxygen(SaO2)and pH value of observation group were(88.96±6.25)mmHg,(92.58±3.15)%and(7.68±1.25),which were higher than those of control group([81.45±6.12]mmHg,[88.69±4.58]%and[7.06±1.17]).The partial pressure of carbon dioxide(PaCO2)was(31.12±4.03)mmHg,which was lower than that of the control group[(36.45±4.18)mmHg],with statistically significant differences(P<0.05).The oxygen therapy time,nCPAP time and hospitalization time in observation group were(87.89±7.85)h,(95.14±9.46)h and(19.58±2.36)d,which were shorter than those in control group([115.46±9.37]h,[130.58±20.76]h and[24.55±4.12]d),with statistically significant differences(P<0.05).The incidence of complications in the observation group was 4.88%,which was lower than that in the control group(19.51%),with statistically significant difference(P<0.05).Conclusion PS combined with nCPAP can enhance the therapeutic effect of NRDS,improve the arterial blood gas index of children,correct the symptoms of hypoxia,shorten the hospitalization time and reduce the occurrence of complications.
