我曾有一位患者,佩戴胰岛素泵3年,对于输注胰岛素的部位清洁非常到位,然而后来有时还是会出现红肿发炎的情况,从而不得不经常变换输注部位。最终有一次,竟然出现了严重的感染,不得不在其后的2个礼拜内每天静脉滴注抗生素。为此,主管医生最后让他撤掉了胰岛素泵,重新回到胰岛素注射治疗。他猜测,会不会是他体内对于胰岛素泵的输注装置产生了“过敏反应”呢?他迫切地想要知道,我以前是不是也见到过这类情况?他究竟该如何应对? I used to have a patient who was wearing an insulin pump for 3 years and was well placed to clean the insulin infusion but later inflamed and sometimes inflamed and had to change infusions frequently. In the end, there was a serious infection, which necessitated intravenous antibiotics daily for the next two weeks. To this end, the competent doctor finally let him withdraw the insulin pump, back to insulin injection therapy. He wondered if he would have an “allergic reaction” to the infusion pump for insulin pumps in his body. He was eager to know if I had ever seen such a thing before, and how he should deal with it ?
