选择适当药物治疗泌尿道感染的准则乃根据治疗目的。1.对粪和阴道菌丛影响少。感染细菌直接来源是阴道和会阴,但其原始贮源是肠菌丛,肠菌丛接触抗菌剂增加移入泌尿道产生抗株的危险,故抗菌剂的作用在后来被新株引起感染所损害。另一治疗目的是避免影响阴道菌丛的抗生素,药物治疗后25％患者可发生酵母菌阴道炎,比原始的泌尿道感染症状较多、难治,故须避免用胃肠道吸收不完全或达到血清高水平的抗菌剂。2.采用价廉达到最大治疗目的的药物。3.能达到尿高浓度。 抗菌剂的选择 表1.代表达到选择准则最好可
The guidelines for choosing the appropriate medication for urinary tract infections are based on the purpose of the treatment. 1. Fecal and vaginal flora less affected. The direct source of infectious bacteria is the vagina and the perineum, but its original source of storage is enterobacteriaceae, enterococci contact with antibacterial agents to increase the risk of moving into the urinary tract to produce anti-strains, so the role of antimicrobial agents was subsequently damaged by a new strain of infection. Another treatment is to avoid the impact of vaginal flora of antibiotics, drug treatment can occur in 25% of patients with yeast vaginitis than the original symptoms of urinary tract infection more difficult to treat, it is necessary to avoid incomplete gastrointestinal absorption or Achieve high levels of serum antimicrobials. 2. Use cheap drugs to achieve the maximum therapeutic purpose. 3. Can reach high urine concentrations. Selection of Antibacterial Agents Table 1. Representatives meet the selection criteria best
