气相色谱分析法在口腔颌面部感染快速诊断中的应用

RAPID DIAGNOSIS OF ORAL AND MAXILLOFACIAL ANAEROBIC INFECTIONS BY GAS CHROMA TO GRAPHY

通过对30例口腔颌面部感染患者脓液标本的气相色谱分析和细菌学培养对照,说明直接应用气相色谱对脓液分析,可初步诊断口腔颌面部的厌氧菌感染。在大多数标本中含有乙酸、丙酸、丁酸、异丁酸、戍酸、乳酸和琥珀酸,与细菌培养的结果基本相符。由于常规的厌氧菌的分离鉴定需要大量的时间,而应用气相色谱可帮助临床医生快速诊断厌氧菌的存在,从而选择有效的治疗药物。

The study on gas chromatography and bacteriology of 30 cases of maxillofacial infections was made. Direct gas cliromatographic analysis of the pus is recommended as a routine procedure for preliminary diagnosis of oral and maxillofacial anaerobic infections. Most of the specimens containing acetic acid, propionic acid, butyric acid, isobutyric acid, valeric acid, lactic acid and succinic acid which were accorded with the result of bacteriologic study. Since the isolation and identification of bacteria by culture are time-consuming methods, the gas chromatigraphy for the rapid presumptive diagnosis of anaerobic infections may be helpful to the clinician and therepy, that allows early institution of proper antimicrobial therapy.
