将72例次医院内感染患者按治疗方法的不同分为两组：①氨曲南治疗组36例40例次（简称治疗组）；②头孢氨噻肟治疗组32例（简称对照组），回顾性地比较两组方案治疗医院内感染患者的疗效，结果示：①治疗组的痊愈率、显效率、好转率和无效率与对照组比较差异有显著性（分别为75．0％vs50．0％、22．5％vs28．1％、2．5％vs15．6％、0．0％vs6．25％，P＜0．05）;②治疗组细菌清除率与对照组比较差异有显著性（90．32％vs69．23％，P＜0．05）。表明对采用氨曲南治疗革兰氏阴性杆菌感染的患者具有疗效好、细菌清除率高、副作用少等优点。
The 72 patients with nosocomial infections were divided into two groups according to different treatment methods: 1 Aztreonam treatment group 36 cases 40 times (referred to as the treatment group); 2 cefotaxime treatment group 32 cases (referred to as the control group), Retrospectively comparing the efficacy of the two groups of programs in the treatment of patients with nosocomial infections, the results showed that: 1 the treatment group cured rate, significant efficiency, improvement rate and inefficiency compared with the control group was significant (75.0% vs50. 0%,22.5% vs28.1%,2.5%vs15.6%,0.0%vs6.25%,P<0.05);2The bacterial clearance rate of the treatment group was significantly different from the control group. Sex (90.32% vs 69.23%, P<0.05). Shows that the use of aztreonam for the treatment of gram-negative bacilli infection in patients with good efficacy, high bacterial clearance, and fewer side effects.
