目的　探讨早产儿的发生原因、并发症和死亡原因。　方法　对我科 1991年 1月～2 0 0 1年 12月 11年期间住院的 83 4例早产儿的围产期临床资料进行回顾性分析。　结果　住院早产儿有逐年增多趋势 ,多数有明确早产的诱因。冬季早产儿住院比例高于其它季节。 87.6%有各种疾病 ,后 6年硬肿症、肺炎、呼吸暂停和颅内出血发生率下降。本组早产儿死亡 64例 ,病死率 7.7% ,胎龄愈小、出生体重愈小 ,病死率愈高 ;早产儿死亡的危险性相关因素依次为 :出生体重、胎龄、生后 1minApgar评分、肺出血、肺透明膜病。　 结论　应加强围产保健措施 ,加强产科儿科合作 ,减少早产儿合并症 ;进一步提高各级围产保健人员对危重早产儿的抢救水平 ,建立区域性围产转运系统 ;在NICU中提高早产儿的管理水平 ,进一步降低早产儿病死率 ,改善其预后 Objective To investigate the causes, complications and causes of death in premature infants. Methods The perinatal clinical data of 83 4 preterm infants hospitalized in our department from January 1991 to December 2011 were analyzed retrospectively. Results The number of hospitalized premature infants increased year by year, most of which have a clear motivation for preterm birth. Winter preterm infants hospitalized than other seasons. 87.6% had various diseases, and the incidence of scleredema, pneumonia, apnea and intracranial hemorrhage after 6 years was decreased. 64 cases of premature death in this group, the fatality rate of 7.7%, the smaller the gestational age, the birth weight is smaller, the higher the mortality rate; risk factors for premature children were: birth weight, gestational age, 1minApgar score after birth, Pulmonary hemorrhage, hyaline membrane disease. Conclusions We should strengthen perinatal care measures, strengthen obstetrics and gynecology cooperation, reduce the complications of premature children; further improve the level of rescue of perinatal health workers at critical levels of preterm infants and establish a regional perinatal delivery system; improve NICU in preterm infants Management level, to further reduce the mortality of premature children and improve their prognosis
