【摘要】 目的　分别按年龄和按体表面积分组研究沿海地区７～１４岁碘充足儿童甲状腺Ｂ超容积的正常上限值。方法用 Ｂ超测量 １４９２名７～１４岁碘充足儿童的甲状腺Ｂ超容积。结果　沿海地区７～１４岁儿童甲状腺Ｂ超容积上限值：Ａ．以年龄分组：７～１４岁儿童分别为３．５１、４．１６、４．８２、５．４８、６．１３、６．７９、７．４４、８．１０；Ｂ．以体表面积分组：体表面积为（０．７～１．５）ｍ２的儿童，甲状腺Ｂ超容积上限值分别为３．１３、３．８２、４．５０、５．１９、５．８７、６．５５、７．２４、７．９２、８．６１，上述结果均低于ＷＨＯ／ＩＣＣＩＤＤ推荐的正常值。结论　ＷＨＯ／ＩＣＣＩＤＤ推荐甲状腺Ｂ超容积正常上限值并不适用于中国儿童，必须根据中国人的种族背景和儿童生长发育的实际状况建立碘充足的中国儿童甲状腺Ｂ超容积的正常上限值。更多还原

【Abstract】 Objectve Study on thyroid ultrasonic normal limit volume of iodine suffcient children aged 7-14 years in coastal area by age and body surface area.Methods 1492 cases were measured by ultrosography B. Result The thyroid normal limit volume were as follows:A.by age:in children from 7 to 14 years partly as 3. 51 、4. 16、4.82、5 .48、6. 13、6.79、7.44、8. 10;B.by body surface area: when the body surface area of children is from 0.7m2 to 1 .5m2,the thyroid’s B model ultrasonic normal limit volume partly as 3. 13、3.82、4.50、5. 19、5. 87、6.55、7.24、7.92、8.61,the results above - mentioned all lower to the normal limit recommend by WHO-IC- CIDD.Conclution The ultrasonic B normal limit volume of thyroided recommend by WHO - ICCIDD is not suitable for the Chinese children, so it is necessary to establish the Chinese thyroid ultrasonic normal limit volume according to the Chinese ethnic background and the actualy state of children’s growth and development.更多还原
