摘要
目的 了解呼吸重症监护室 (RICU )中呼吸功能不全患者下呼吸道感染病原菌的流行状况及来源。方法 对 1999年 10月~ 2 0 0 0年 3月入住RICU患者的痰及相关部位的标本 (氧气湿化瓶、呼吸机管道、留置导尿的尿标本等 )采样送检。结果 RICU 2 6例患者 ,发生下呼吸道感染 18例 (6 9.2 3% ) ,其中 16例为有创机械通气患者 (88.89% ) ;病原菌多数为非发酵菌 (4 1.84 % )。结论 RICU内下呼吸道感染发生率高 ,多为有创机械通气患者 ,病原菌多为非发酵菌。
OBJECTIVE To investigate the epidemiological conditions of lower respiratory tract infections and their origins in respiratory intensive care unit (RICU). METHODS From Oct 1999 to Mar 2000, sputum specimens from the patients in RICU and other relevant specimens(from oxygen enriched bottle, output duct of ventilatory apparatus, and urethral catheter, etc.) were collected and identified. RESULTS Among 26 patients in RICU, 18 patients had lower respiratory tract infection (69.23%), and 16 infected patients were intubated (88 89%). Nonfermentative bacteria were the dominant pathogens(41.84%). CONCLUSIONS The occurrence rate of lower respiratory tract infection was high. Most infected patients were intubated. The common pathogens were nonfermentative bacteria.
