[The infectious risk in neonatal surgery : an evaluation of frequency and consequences from a study of 300 cases (author's transl)].

This study is an evaluation of the infectious risk related to neonatal surgery in 300 patients between 1968 and 1978, and its consequences to mortality and morbidity. Bacteriological species, circumstances, chronology of infection, related to each type of surgical pathology prove the endogenous way of contamination to be usual and predominant. When intestinal obstruction occurs, the risk of hematogenous diffusion is directly dependent from local stasis and bacterial pullulation which can be evaulated with duodenal, jejunal or fecal samples. Both mechanical factors and antibiotictherapy can induce qualitative and quantitative changes in bacterial flora of the bowel, and then increase the incidence of endogenous septicemia.
