The occurrence of bacteremia was studied in patients undergoing barium enema. Blood cultures were done on 34 patients before, during, and after the procedure using two schedules. Cultures were obtained once during the procedure in the first schedule and four times in the second. None of the cultures were positive by the first schedule, while 23% of patients studied by the second schedule had one or more positive cultures. Organisms isolated were anaerobes. The bacteremia was transient and self-limited, without serious clinical sequelae. The incidence of bacteremia during barium enema examination was statistically indistinguishable from bacteremia previously reported during colonscopy. It is concluded that antibiotic prophylaxis is not indicated in most patients undergoing colonic diagnostic procedures. Prophylaxis in selected high-risk patients requires further study.
对接受钡灌肠检查的患者的菌血症发生情况进行了研究。采用两种方案，在34例患者检查前、检查期间和检查后进行了血培养。第一种方案在检查期间进行一次培养，第二种方案进行四次培养。第一种方案的培养结果均为阴性，而第二种方案检查的患者中有23%的培养结果为一次或多次阳性。分离出的微生物为厌氧菌。菌血症是短暂的且有自限性，无严重临床后遗症。钡灌肠检查期间菌血症的发生率与先前结肠镜检查期间报告的菌血症在统计学上无显著差异。结论是，大多数接受结肠诊断程序的患者无需使用抗生素预防。对选定的高危患者进行预防需要进一步研究。
