Cellulitis: initial management.
Although Staphylococcus aureus and Streptococcus pyogenes cause the majority of cellulitis, recent studies have shown a significant role for Hemophilus influenzae in facial, and less frequently, nonfacial infections. We devised an algorithm for the initial management of cellulitis based on our previous investigations showing a correlation of this organism with fever, leukocytosis, and facial involvement. Children were divided into four groups characterized as follows: Group I - extremity, temperature less than 38.5 C; Group II - extremity, temperature greater than 38.5 C, WBC less than 15,000/cu mm; Group III - extremity, temperature greater than 38.5 C, WBC greater than 15,000/cu mm; and Group IV - facial. Forty-five children were successfully followed. There were 34 in Group I, five in Group II, one in Group III, and five in Group IV. Two children in Group IV and the only child in Group III had H influenzae, recovered form the blood (3) or a direct aspirate (1). All three were febrile, with a range of 39.5 C to 40.1 C and has an elevated white blood cell count with a range of 19,200/cu mm to 26,000/cu mm. With one exception, children with cellulitis not due to H influenzae did not have both fever and leukocytosis. This algorithm allows the clinician to identify children with H influenzae cellulitis who are at risk for septic complications while minimizing unnecessary diagnostic or therapeutic interventions.
