早产儿呼吸窘迫综合征经鼻间歇正压通气治疗的Meta分析

Objective To agsess the efficacy of nasal intermittent positive pressure ventilation (NIPPV)in treatment of respiratory distress syndrome(RDS) in premature infants.Methods According to the requirements of Cochrane systematic review,a thorough literature search was performed among PubMed(1977-2008),Embase(1989-2008),OVID,Cochrane(2008),Chinese Digtal Hospital Library (www.chkd.cnki.net) and Chinese Biomedical Literature Disk Database(CBMdisc).Quality assessments of clinical trials were carried out Randomized controHed trials(RCTs)with NIPPV and RDS were enrolledand ReVnlan 4.2 software was used for meta-analysis.The trials were analyzed using relatire risk(RR) for dichotomous data,weighted mean difference(WMD) were used for continuous data,both kind of data were expressed by 95% confidence intervals(95%CI).For homogenous data(P≥0.10),fixed effects model was calculated,for heterogeneity data(P<0.10),random effects model was calculated.Results Five RCTs involving 284 premature infants diagnosed as respiratory distress syndrome(RDS) were included.Three studies comparing NIPPV with nasal continuous positive airway pressure(NCPAP) in the postextubation period,tHe extabation failure rate was 8.34%vs 40.79% in NIPPV group and NCPAP group,the NIPPV group had significantly lower extubation failure rates[RR 0.21(95%CI:0.10-0.45;P<0.001)].Two of the above.mentioned three studies analyzed bronchopulmonary dysplasia(BPD)rates,the incidence of BPD was 39.34%vs 54.39%in NIPPV group and NCPAP group,the NIPPV group had a trend towards lower BPD rates,but this did not reach statistical significance[RR 0.73(95%CI:0.49-1.07;P=0.11)].NIPPV was used as primary mode in two studies,one compared with conventional ventilation(CV),which detected that the NIPPV group had significantly lower BPD rates(10% vs.33.33%,P:0.04);the other compared with NCPAP,which also showed that NIPPV group had significantly lower BPD rates(2.33% vs.17.07%,P=0.03).Conclusion The primary mode NIPPV was found to be feasible as a method of ventilation in preterm infants with RDS,and Was associated with a decreased incidenee of BPD.In the postextubation period,NIPPV is more effective in preventing failure of extubation than NCPAP.
