烧伤患者痂下水肿液感染源的初步分析

A preliminary analysis of infectious source of subeschar edema fluid in burn patients

目的分析烧伤痴下水肿液的细菌感染来源。方法收集临床痴下水肿液标本27人份，普通培养后，以Vitek－AMS作细菌鉴定，并同时作同一部位或相邻部位创面分泌物细菌鉴定行比较。结果（1）痂下水肿液细菌培养阳性率为37％（10／27），创面细菌培养阳性率为85％（23／27）：（2）痂下水肿液10份阳性结果中创面培养结果同时阳性的有9份，细菌种类一致者为70％（7／10），不相同者为20％（2／10）：（3）痂下水肿液中检出细菌以G杆菌为主60％（6／10），亦可见G＋球菌，30％（3／10）和混合生长者10％（1／10）。结论上述结果提示痴下水肿液细菌主要来自创面，但也有少数来源不明确，可能与内源性感染有关。

Objective To clarify the infectious source of subeschar edema fluid (SEF) in bum patients. Methods Twenty-sevensamples of SEF and corresponding wound excretions (Cab) were collected simultaneously and then isolated for bacteriaidentification with auto-microbial System (Vitek-AMS). ResultS (l) Positive rate of bacterial cultUre was 37% (10/27) in SEFsamples and 85% (23.27) in Cab samples. (2) In accord with the 10 positive samples of SEr, 9 samples of CWE were positive forgroWth of bacteria, of which 7 had the identical bacteria. (3) The grab-negative bacilli appeared predominant (60%) in SEF, andgram-positive cocci were relatively less found (30%); the mixed groWth was also found in one sample (10%) of them. ConclusionsMost bacteria of SEF were derived mainly from bum wound. Though the bacterial source was not clear in some samples, it isprobably related to endogenous infection such as bacterial translocation from the gUt.
