To determine the epidemiologic characteristics of hospital-acquired infections (HAI) in pediatric burn patients, we retrospectively reviewed hospital charts of pediatric burn patients from two similar burn units. All patients less than 18 years of age admitted to the burn unit from January 1, 1980 to July 10, 1988, were enrolled. Charts were analyzed for age, sex, burn injury (type, depth, burn surface area), and hospital course (burn wound therapy, use of indwelling catheters or tubes, infectious complications, antibiotic use, cause of death if patient died). Statistical analysis was done using a logistic regression model. Of the 224 children admitted, 32 (14%) had 58 infections during their stay in the burn unit. There was no significant difference in age, sex, race, burn type or use of wound excision between patients with or without infection. Patients who acquired an infection were more likely to have sustained a > or = 20% full-thickness burn (14/32 vs 3/192 without infection), a smoke inhalation injury (10/32 vs 8/192), or have an indwelling device (29/32 vs 77/192). Thirteen (22%) of the 58 infections were burn wound infections due to Staphylococcus aureus or Pseudomonas aeruginosa, 12 (21%) were urinary tract infections due to Enterobacteriaceae, 11 (19%) were pneumonias caused by S aureus, Streptococcus pneumoniae or Pseudomonas sp, and 10 (17%) were bacteremias caused by S aureus or coagulase-negative staphylococci. The infection rate in pediatric patients hospitalized for burn injury in our study was significantly lower than the infection rate described for adult burn patients. As in adult patients, burn wound infections, pulmonary infections, and catheter-associated bacteremias are the most common infections in burned children. However, urinary tract infections are more frequent in the pediatric population. Risk factors (> or = 20% full-thickness burns, indwelling devices) and causative organisms are similar in both age groups.
为确定小儿烧伤患者医院获得性感染(HAI)的流行病学特征,我们回顾性分析了来自两个相似烧伤病房的小儿烧伤患者的病历。纳入了1980年1月1日至1988年7月10日期间入住烧伤病房的所有18岁以下患者。分析病历以获取年龄、性别、烧伤情况(类型、深度、烧伤面积)及住院过程(烧伤创面治疗、留置导管或引流管的使用、感染并发症、抗生素使用情况,若患者死亡则为死亡原因)。采用逻辑回归模型进行统计分析。在224名入院儿童中,32名(14%)在烧伤病房住院期间发生了58次感染。感染患者与未感染患者在年龄、性别、种族、烧伤类型或伤口切除的使用方面无显著差异。发生感染的患者更有可能遭受≥20%的全层烧伤(14/32对比未感染患者中的3/192)、吸入性损伤(10/32对比8/192)或有留置装置(29/32对比7××192)。58次感染中有13次(22%)为金黄色葡萄球菌或铜绿假单胞菌引起的烧伤创面感染,12次(21%)为肠杆菌科细菌引起的尿路感染,11次(19%)为金黄色葡萄球菌、肺炎链球菌或假单胞菌属引起的肺炎,10次(17%)为金黄色葡萄球菌或凝固酶阴性葡萄球菌引起的菌血症。我们研究中因烧伤住院的小儿患者的感染率显著低于成人烧伤患者所描述的感染率。与成人患者一样,烧伤创面感染、肺部感染及导管相关菌血症是烧伤儿童中最常见的感染。然而,尿路感染在儿童人群中更为常见。两个年龄组的危险因素(≥20%的全层烧伤、留置装置)及致病微生物相似。
