本研究应用放射免疫法测定63例新生儿脐血和血清中精氨酸加压素（AVP）的含量变化，发现窒息儿脐血和静脉血AVP含量明显高于健康儿，提示新生儿窒息对在刺激新生儿体内释放AVP的机制中起重要作用，并发现胎儿宫内缺氧是一个潜在刺激AVP释放的因素。脐血AVP的含量可早期反映新生儿体内AVP的含量，因此，脐血AVP的测定，对于患儿高危状态的估计，指导早期治疗具有重要的参考价值。
In this study, radioimmunoassay was used to determine the levels of arginine vasopressin (AVP) in 63 newborn infants and their serum. The levels of AVP in cord blood and venous blood of asphyxiated children were significantly higher than those in healthy children, suggesting that neonatal asphyxia Plays an important role in stimulating the mechanism of AVP release in newborns and found that intrauterine hypoxia is a potential contributor to the release of AVP. The level of AVP in umbilical cord blood can reflect the content of AVP in newborns at early stage. Therefore, the determination of AVP in umbilical cord blood has an important reference value for the estimation of high risk status in children and early treatment.
