Résumé
To investigate the curative effect of Medtronic merocel packing after endoscopic sinus surgery,76 patients underwent endoscopic sinus surgery in the Department of Otolaryngology,Xiangfan Hospital,Tongji Medical College,Huazhong University of Science and Technology from June to December in 2004,were adopted in this study and randomly divided into two groups:36 cases in observation group were packed with Medtronic merocel sponge,40 cases in control group with Vaseline gauze,the nasal pain and haemostasis effect after the package removal were observed.The result showed that,the incidence rate of nasal pain and haemostasis in the observation group was significantly lower than that in the control group(P
Résumé
Objectives To study the characteristics of clinical distribution of enterococci, to test its sensitivity to antibiotics recommended by NCCLS, and to promote rational use of antibiotics. Methods A total of 381 strains of enterococci isolated from Hubei during January to December 2001 were tested for their sensitivity to antibiotics and production of beta-lactamases with paper disk diffusion method. Results Among 381 strains of enterococci, there were 78.0% of E. faecalis, 19.4% E. faecium, 1.6% E. durans, 0.53% E. avium, 0.3% E. hirae and 0.3% E. solitarium , and beta-lactamases-producing enterorocci accounted for 3.2% of the total. And, 46.5% of the strains were isolated from uroreproductive tracts samples, ranking the first of the total, possibly because of some samples from a hospital specialized in urology, 35.4 % from respiratory tract, ranking the next, and 11.0% form skin pustule and infected wound, ranking the third. Proportions of the strains resistant to varied antibiotics were 5.8%, 7.9%, 11.0%, 24.7%, 26.8%, 38.6%, 54.6%, 54.6%, 52.5% and 79.3% to vancomycin, teicoplanin, nitrofurantoin, ampicillin, penicillin, ciprofloxacin, chloromycetin, high concentration gentamycin, high concentration streptomycin, and tetracycline, respectively. Drug-resistant rate of E. faecium was higher than that of E. faecalis. Conclusions Enterococci, most of them identified as E. faecalis and E. faecium, were isolated from samples of uroreproductive and respiratory system, and the most susceptible to vancomycin. E. faecium was more resistant to antibiotics than E. faecalis.
