目的 :探讨小儿特重烧伤败血症的临床特点及其意义。方法 :对 1990～ 1996年 80例小儿特重烧伤病例进行回顾性调查 ,有临床表现且抽血进行普通培养及厌氧培养 ,阳性者定为败血症 ,对败血症发生时间、临床表现、菌种及治疗结果进行调查及分析。结果 :80例中有 2 2例为败血症 ,其发生率为 2 7.5 % ,败血症大多数(17/ 2 2 )发生在伤后 1周内 ,并持续 3～ 7d。 36次血培养阳性标本中共分离出 12种 42株细菌 ,需氧菌占 40 .46 % ,主要为绿脓杆菌和金黄色葡萄球菌。厌氧菌占 5 9.5 4% ,以厌氧消化球菌及厌氧脆弱类杆菌为主。 2 2例败血症治愈 18例 ,其余 4例死亡 ,死亡率为 18.18%。结论 :根据小儿特重烧伤败血症自身特点 ,进行有效的防治可降低其死亡率 Objective: To investigate the clinical features and significance of pediatric severe burn sepsis. Methods: A retrospective study was performed on 80 cases of pediatric severe burn patients from 1990 to 1996. The patients were clinically expressed and blood was taken for general culture and anaerobic culture. The positive rate was defined as sepsis. The time of sepsis, clinical manifestation, Treatment results were investigated and analyzed. RESULTS: Twenty-two of 80 patients had sepsis, with a rate of 21.5%. Most of the sepsis (17/22) occurred within 1 week after injury and lasted for 3 to 7 days. Thirty-two strains of 42 bacteria were isolated from 36 blood culture positive samples, accounting for 40.46% of aerobic bacteria, mainly Pseudomonas aeruginosa and Staphylococcus aureus. Anaerobic bacteria accounted for 5 9.54%, with anaerobic digestion cocci and anaerobic Bacteroides-based. Twenty-two cases were cured of sepsis and the remaining four were dead with a mortality rate of 18.18%. Conclusion: According to its own characteristics of pediatric severe burn sepsis, effective prevention and treatment can reduce the mortality rate
