目的：比较力确兴与复达欣治疗绿脓杆菌下呼吸道感染的安全有效性。方法：采用随机对照试验设计，全部病例均为住院患者，试验组２０例，力确兴注射液，每次２００ｍｇ每日２次（每２小时１次），溶于１００～２００ｍｌ０９％氯化钠溶液或５％葡萄糖溶液中稀释，滴注时间１小时半至２小时。对照组１９例，复达欣２ｇ溶于５％葡萄糖溶液２００ｍｌ中静脉滴注，每日２次。试验组和对照组疗程均为７～１４天。一般资料相似（Ｐ＞００５）。结果：试验组与对照组临床疗效比较治疗前后发热病人体温转为正常的天数、白细胞增加的病人７天后白细胞转为正常的例数均无显著性差异（Ｐ＞００５）。治疗结束后，试验组２０例中１３例治愈；对照组１９例中１４例治愈，两组的治愈率分别为６５％和７３７％（Ｐ＝０９００）。试验组和对照组显效、进步、无效分别为２例和１例、２例和２例、３例和２例，两组均无显著性差异（Ｐ＝０７５０～０９００）。有效例数分别为１７例（８５％）和１７例（８９５％），以对照组为高，但无统计学差异（Ｐ＝０９５０）。药物敏试结果发现３７株绿脓杆菌对力确兴敏感（包括高敏和中敏），３６株对复达欣敏感；２株对力确兴耐药，３株对复达欣耐药。经统计学处?
OBJECTIVE: To compare the safety and efficacy of Fu Daxin and Fu Daxin in the treatment of Pseudomonas aeruginosa lower respiratory tract infection. Methods: A randomized controlled trial was designed. All patients were hospitalized. Twenty patients in the experimental group were treated with 200 mg twice daily (once every 2 hours) and dissolved in 100-200 ml of 0.9% chlorine Sodium solution or 5% glucose solution, the infusion time of 1 hour and a half to 2 hours. In the control group, 19 cases were treated with intravenous drip of 2g of Fuda Dansu in 200ml of 5% dextrose solution twice daily. The treatment group and control group were 7 to 14 days course of treatment. The general information is similar (P> 005). Results: Compared with the control group, the clinical efficacy of the test group and the control group were normal before and after treatment. The number of leukocytosis cases after 7 days of leukocytosis was no significant difference (P> 0.05). After the treatment, 13 cases were cured in 20 cases in experimental group and 14 cases in control group, and the cure rate in both groups was 65% and 737%, respectively (P = 0.900). Two cases and one case, two cases and two cases, three cases and two cases were found in the experimental group and the control group. There was no significant difference between the two groups (P = 0750 ~ 0900). The effective cases were 17 cases (85%) and 17 cases (895%), respectively. The control group was high, but no significant difference (P = 0.950). Drug susceptibility test results found that 37 strains of Pseudomonas aeruginosa really sensitive Xing (including high sensitivity and moderate sensitivity), 36 strains of Fu Daxin sensitive; 2 strains of resistance really Xing, 3 strains of resistance to Fu Xin.
