摘 要: 选择1只红火蚁叮蛰手掌腕部皮肤1次,观察受蛰部位的症状表现及变化。结果显示从叮蛰引起红肿开始到症状完全消失痊愈大约需要20d左右的时间,其中要经过发生红肿、产生脓疱、结痂痊愈3个阶段,并伴随有4~5次发痒。该变化过程有助于医生和患者判断是否是受到红火蚁叮蛰,并大致断定所处阶段。 A red imported fire ant stung the wrist fonce, that the symptom would last for more or less 20 days until and then the symptom was observed. The result indicated it recovered. The whole changing process of the symptom can be divided into three phases: swelling, forming pustule, and recovering. The stung site itched for 4 or 5 times through the 20 days. This record of the symptom change can be helpful for the doctor to decide whether the patient suffered the sting of RIFA or not, and which phase the symptom is at.
