Estudio controlado con grupos paralelos y abierto de la eficacia clínica y microbiológica de piperacilina-tazobactam frente a metronidazol más gentamicina en cirugía colorrectal urgente

The association of piperacillin-tazobactam was more effective than that of metronidazole and gentamicin in the prevention and treatment of local infection in the treated groups. Therapeutic failure was mainly related to the presence of Gram-negative bacteria.
