本文报告40例轻、重度新生儿窒息时血清钙浓度变化,发现窒息儿血钙浓度降低,且与窒息严重程度有关,结果分析如下。 1 资料与方法 1.1 一般资料 新生儿出生时有重度窒息(Apgar评分<4分)21例,其中有缺血缺氧性脑病13例。轻度窒息(Apgar评分4～7分)19例。早产儿5例,足月儿35例。体重≥2500g34例,<2500g6例。产式:异常分娩27例,正常分娩13例。对照组13例均为足月顺产儿,出生体重≥2500g,Apgar评分8～10分。 1.2 症状与体征 肌张力增高13例,肌张力降低19例。拥抱反射增强11例,减弱9例,消失3例。抽搐6例,中枢性呼吸衰竭2例。 1.3 方法 采血时间为生后24h之内,均为股静脉采血。由我院检验科采用日本岛津产7200型全自动生化分析仪测定血清钙浓度。 1.4 统计学分析方法 数据以±s表示,应用t检验。
This article reports 40 cases of mild to severe neonatal asphyxia serum calcium concentration found in children with asphyxia serum calcium concentration, and the severity of asphyxia, the results are as follows. 1 Materials and Methods 1.1 General Information Neonatal at birth with severe asphyxia (Apgar score <4 points) in 21 cases, of which 13 cases of hypoxic-ischemic encephalopathy. Mild asphyxia (Apgar score 4 to 7 points) 19 cases. 5 cases of premature children, full-term children in 35 cases. Weight ≥ 2500g34 cases, <2500g6 cases. Type: abnormal delivery in 27 cases, 13 cases of normal labor. Control group, 13 cases were full-term, birth weight ≥ 2500g, Apgar score 8 to 10 points. 1.2 Symptoms and signs of increased muscle tension in 13 cases, 19 cases of decreased muscle tone. Hugging reflex enhancement in 11 cases, weakened in 9 cases, disappeared in 3 cases. Twitch in 6 cases, 2 cases of central respiratory failure. 1.3 Methods Blood collection time within 24 hours after birth, are femoral vein blood. By our hospital laboratory Japan Shimadzu 7200 automatic biochemical analyzer serum calcium concentration. 1.4 Statistical Analysis Methods Data to ± s that the application of t test.
