The aim of this study was to evaluate bacterial flora infecting during the surgical procedures the peritoneal cavity and drains which were used after the surgery in 40 patients who underwent surgery for colon and rectum tumors. Smears from the peritoneal cavity, liquid removed from the drain taken at 3-4 days after the surgery and smears from the drain taken at the end of drainage of each patient were examined for bacterial content. The comparison of bacterial flora found in the peritoneal cavity with bacteria found in drains showed that the frequency of isolation of anaerobes decreased in contrast to aerobes which were more often cultured over the time of drainage (p < 0.05). Bacteroides spp, enterococci, and strains of Enterobacteriaceae were most often isolated from the peritoneal cavity, but over the time of drainage the frequency of isolation of coagulase-negative staphylococci including MRCNS increased as well as the number of patients infected with enterococci, whereas anaerobes and strains of Enterobacteriaceae were rarely isolated.
本研究旨在评估40例接受结肠和直肠肿瘤手术患者在手术过程中感染腹腔的细菌菌群以及术后使用的引流管情况。对每位患者腹腔的涂片、术后3 - 4天从引流管取出的液体以及引流结束时引流管的涂片进行细菌含量检查。将腹腔中发现的细菌菌群与引流管中发现的细菌进行比较，结果显示厌氧菌的分离频率降低，而需氧菌在引流期间培养得更为频繁（p < 0.05）。拟杆菌属、肠球菌和肠杆菌科菌株最常从腹腔中分离出来，但在引流期间，包括耐甲氧西林凝固酶阴性葡萄球菌在内的凝固酶阴性葡萄球菌的分离频率增加，同时感染肠球菌的患者数量也增加，而厌氧菌和肠杆菌科菌株很少被分离出来。
