今天在美国ASHP(American Society of Health-System Pharmacist)等学会联合发布的《Clinical practice guidelines for antimicrobial prophylaxis in surgery》中看到如下这句话:Where there is increasing resistance to first- and second-generation cephalosporins among gram-negative isolates from SSIs, a single dose of ceftriaxone plus metronidazole may be preferred over the routine use of carbapenems.
于是有一个疑问,头孢菌素类与碳青霉烯类抗菌药物存在交叉耐药吗?
