摘要
目的探讨延长小儿皮试观察时间对皮试结果的影响。方法遵医嘱对500例患儿按常规进行抗生素皮试,在20min时对可疑阳性患儿的皮丘、红晕进行标记,延长10min(即30min时)再次判断。比较不同观察时间下的皮试阳性率和皮试阳性者红晕硬结范围。结果20min时观察结果的阳性率高于30min时观察结果的阳性率(p<0.01),20min时观察结果皮试阳性红晕硬结范围在1.0～1.5cm的患儿人数较30min时观察结果的患儿多(p<0.01),差别均有统计学意义。结论延长小儿皮试观察的间隔时间,降低了皮试阳性率,可以增加患儿用药的机会。
Objective：To compare the effects of the two different moments to judge the results of the skin-tests for children.Methods：500 children were treated by the antibiotics skin-tests as the prescriptions.After 20 minutes,we marked the skin pimples and redness range on some children with doubted positive results.They were judged again in 10 minutes after the former 20 minutes.The positive rate and the redness range were compared between the two different moments.Results：The antibiotics skin-test positive rate on 20 minutes was higher than that of the 30 minutes （p〈0.01）.The patients with smaller redness range （1.0-1.5cm） observed on 20 minutes were more than that of the 30 minutes （p〈0.01）.Conclusion：Judging the results of the antibiotics skin-test for children on 30 minutes could decrease the positive rate and increase the chance of using antibiotics in children.
