The pathogens and curative effects analysis of perianal abscess of infants under 3 months

In order to guide clinical treatment for perianal abscess of young infants,the characteristics of pathogens and curative effects analysis were conducted.Bacterial culture results, antibiotics susceptibility tests and curative effects ofabscess incision were retrospectively analyzed in 66 cases of perianal abscessof infants under 3 months. There were 48 cases of Klebsiella pneumoniae, 7cases of Staphylococcus, 6 cases of Escherichia coli, 5 cases of Proteus in thepathogen culture results. Klebsiella pneumoniae, the predominant pathogen,was susceptible to most antibiotics, especially to imipenem, cefoperazonesulbactam and amikacin with low drug resistance rates. However, high drugresistance rates were found to ampicillin and nitrofurantion. After abscessincision, the complication rate of anal fistula was 6.6％ in infants under3 months and 60.3％ in the adult group. There was significant differenceP＜0.01. In conclusion, Klebsiella pneumoniae was the most common pathogenin perianal abscess of infants under 3 months and was commonly resistantto ampicillin and nitrofurantion. Since perianal abscess of infants under 3months is a self-limited disorder, simple surgical intervention and synchronoussensitive antibiotic administration are suggested as the optimal management.
