目的:探讨早产儿脑室内出血(IVH)的发生率及其影响因素。方法:对2004年6月~2005年6月我院新生儿科收治的早产儿143例,于生后3~7天应用B超诊断仪进行床边头颅B超检查。结果:143例早产儿平均胎龄(33·5±2·03)周,平均体重(2128±524)g,早产儿脑室内出血的发生率为35·0%,重度IVH占14·0%,早产儿胎龄越小、出生体重越低,发生率愈高,其出血程度也较重。围生期窒息、疾病因素及机械通气等与早产儿脑室内出血密切相关。结论:早产儿脑室内出血发生率高,有严重合并症者发生率增高,且大多无症状,常规进行床边头颅B超检测,可早发现、早治疗。
Objective: To investigate the incidence of premature infants with intraventricular hemorrhage (IVH) and its influencing factors. Methods: From June 2004 to June 2005, 143 cases of preterm infants admitted to neonatology department of our hospital were examined by B-mode ultrasonography with B-mode ultrasonography instrument from 3 to 7 days after birth. RESULTS: The average gestational age (33.5 ± 2.03) weeks, average body weight (2128 ± 524) g, preterm infants with intraventricular hemorrhage (35.0%), severe IVH (14.0%), Premature children gestational age smaller, lower birth weight, the higher the incidence, the degree of bleeding is also heavier. Perinatal asphyxia, disease factors and mechanical ventilation are closely related with intraventricular hemorrhage in preterm infants. Conclusion: The incidence of intraventricular hemorrhage in premature infants is high. The incidence of severe complications is high, and most of them are asymptomatic. Bedside craniocerebral ultrasonography can be routinely performed to detect and treat early.
