Septicemia is the major cause of morbidity in home parenteral nutrition patients, accounting for approximately 70% of rehospitalizations. To identify risk factors, the incidence of infection was examined in 41 current home parenteral nutrition patients, 30 with short-bowel syndrome (including 16 with inflammatory bowel disease and 11 with bowel infarction) and 11 with chronic obstructive disorders. Management, which was followed for a mean duration of 78.6 months (range, 1 to 15 1/2 years), was standardized by protocol. Ten patients never experienced infection during the average follow-up of 61 months (range, 14 to 174 months), whereas seven patients experienced frequent infections during the mean follow-up of 77 months (range, 24 to 180 months). Significant distinguishing features in the frequent-infection group were younger age (45 +/- 12 vs 66.9 +/- 14.3 years, p < .05), Crohn's disease (in five of seven vs zero of 10 subjects, p < .05), jejunostomies (in seven of seven vs one of 10 subjects, p < .0005), and central vein thrombosis (in five of seven vs zero of 10 subjects, p < .05). A greater proportion of the frequent-infection group had poor catheter-care technique and more were smokers. One hundred fifty septicemias were confirmed by blood culture, giving an average infection rate of one every 31 months, 52% caused by Gram-positive organisms (chiefly coagulase-negative staphylococci and Staphylococcus aureus), 30% caused by Gram-negative organisms, and 16% caused by fungus (chiefly Candida albicans).(ABSTRACT TRUNCATED AT 250 WORDS)
败血症是家庭肠外营养患者发病的主要原因,约占再次住院的70%。为了确定危险因素,对41例当前接受家庭肠外营养的患者进行了感染发生率检查,其中30例患有短肠综合征(包括16例炎症性肠病和11例肠梗死),11例患有慢性阻塞性疾病。治疗按照方案进行标准化,平均持续时间为78.6个月(范围为1至15.5年)。在平均61个月(范围为14至174个月)的随访中,10例患者从未发生感染,而7例患者在平均77个月(范围为24至180个月)的随访中频繁发生感染。频繁感染组的显著区别特征为年龄较小(45±12岁对66.9±14.3岁,p<.05)、克罗恩病(7例中的5例对10例中的0例,p<.05)、空肠造口术(7例中的7例对10例中的1例,p<.0005)以及中心静脉血栓形成(7例中的5例对10例中的0例,p<.05)。频繁感染组中导管护理技术差的比例更高,吸烟者更多。通过血培养确诊了150例败血症,平均感染率为每31个月1例,52%由革兰氏阳性菌引起(主要是凝固酶阴性葡萄球菌和金黄色葡萄球菌),30%由革兰氏阴性菌引起,16%由真菌引起(主要是白色念珠菌)。(摘要截短于250字)
