胸心外科住院病人咽拭与非咽拭标本细菌及药敏分析

目的:通过对胸心外科住院病人咽拭与非咽拭标本细菌及药敏结果分析，探讨咽拭与非咽拭标本细菌及药敏结果的临床意义。方法:收集自2002年8月1日～2003年7月31日细菌培养结果，按咽拭与非咽拭标本两类整理汇总。结果:咽拭标本共得到386株细菌和真菌，非咽拭标本共得到402株纠菌和真菌。咽拭与非咽拭标本主要细菌有很大差异，相同细菌咽拭与非咽拭细菌耐药性有巨大差异。结论:入院后立即做的咽拭检查结果不能用于预测医院感染的情况；非咽拭标本细菌耐药性增加和菌群变化说明了存在抗生素的不合理应用。

Analysis of the Pathogens Composition and Resistance of Pharynx-mop and Non-pharynx-mop Sample from In-patients in Chest-cardio Surgery Ward

Objective: To analyze of the pathogens composition and resistance of pharynx-mop and non- pharynx-mop sample from in-patients in chest-cardio surgery ward at Shanghai Chest Hospital, we explored the clinical meaning of pharynx-mop and non- pharynx-mop sample analyzing. Methods: The data on bacterial susceptibility testing of clinical isolates from Aug. 1,2002 to Jul. 31, 2003 were collected, and divided in two species for analysis, pharynx-mop sample and non- pharynx-mop sample. Results: A total of 386 strains were isolated from pharynx-mop sample, and 402 strains from non-pharynx-mop sample. They have more different in pathogens composition and resistance. The bacterial antibiotic-resistance from non-pharynx-mop sample is higher than from pharynx-mop sample. Conclusion: The result from pharynx-mop sample,examined immediately after in-patient, can not forecast the nosocomial infection. The increase and change of bacterial antibiotic-resistance from non-pharynx-mop sample show the usage of antibiotic unreasonable.
