该文作者通过对气胸伴有低血压的极低体重儿(VLBWI)中第3或4级脑室内出血的发生率进行研究,并与气胸和正常血压的 VLBWI 的脑室内出血的发生率进行比较。对象和方法对1983年1月1日到1986年12月31日出生,胎龄32周以下,需要机械通气的呼吸窘迫综合征(RDS)伴气胸的67名患儿进行回顾性研究,36名伴有低血压,31名血压正常。系统性低血压的定义是:平均血压突然下降到该年龄平均血压的2个标准差以下。脑超声波扫描前死亡者由尸检来验证脑室内出血的严重程度。记录每个婴儿的出生体重,性别,种族,胎龄,Apgar 评分,产科并发症,第1次气胸发生的时间,生后12小时和第1次气胸以前即刻安装呼吸机,机械通气和氧疗的总天数和病死率。
The authors studied the incidence of grade 3 or 4 intraventricular hemorrhage in VLBWI patients with pneumothorax and hypotension and compared the incidence of intraventricular hemorrhage with VLBWI with pneumothorax and normotensive subjects. Subjects and Methods A retrospective study was conducted on 67 children with respiratory distress syndrome (RDS) with pneumothorax who were born between January 1, 1983, and December 31, 1986 and had a gestational age of 32 weeks or less, and 36 companions Have low blood pressure, 31 normal blood pressure. Systemic hypotension is defined as a sudden drop in mean blood pressure below two standard deviations from the mean blood pressure at that age. Autopsies were used to verify the severity of intraventricular hemorrhage in those who died before the brain ultrasound scan. Record birth weight, sex, race, gestational age, Apgar score, obstetric complications, timing of pneumothorax in each infant, ventilator, mechanical ventilation, and oxygen therapy immediately prior to pneumothorax 12 hours after birth The total number of days and fatality rate.
