摘要
目的：比较在不同部位静脉注射荧光素钠的造影效果。方法：使用NiKon NF-505眼底荧光造影机，对4152例患者进行造影检查时，将荧光素钠注射部位由肘静脉改为手背静脉。此法所用的一次性使用静脉输液针为0．55～18规格，药剂的注速为4～6s。注射、拍照需由2人分别操作减为1人操作。结果：手背视网膜循环时间平均为20．2s，比臂视网膜循环时间略长，但造影结果不受影响。结论：眼底荧光血管造影改良方法采用手背静脉注射荧光素钠，安全可行，工序简化，有利于患者。
Objective： To compare the effects of fundus fluorescein angiography（FFA） using different infusion routes of the contrast. Methods： Four thousand and one hundred fifty two patients underwent FFA using Nikon NF-505 fundus fluorescein angiography device. The puncture site of contrast infusion was shifted from anterior arm which was used conventionally to hand . The mode of the disposable needle for intravein was 0.55-18, the speed of contrast infusion was 4-6 mL/s. All procedures, namely contrast administration and photographs taking, once usually done by two persons, were completed by one. Results： The mean circulating time of the infused contrast from hand to retina was 20.2 seconds, which was slightly longer than that of anterior arm to retina, the effect of imaging wasn＇t impaired. Conclusion： The modified method of FFA is safe, feasible, simplify and beneficial to patients.
