[Experience with the combination mezlocillin/oxacillin in severe bacterial infections in a children's surgical ward (author's transl)].

Severe bacterial infections accompanying conditions during childhood which demand for surgical intervention mostly are caused by Staph. aureus, E. coli, Klebsiella/Aerobacter or Ps. aeruginosa. 20 patients, 10 of them suffering from a putrid peritonitis, showed a good efficacy of Optocillin (Bay 1-1330), a combination of 6-((R)-2-[3-methylsulfonyl-2-oxo-imidazolidine-1-carboxamido]-2-phenyl-acetamido)-penicillanic acid sodium salt (mezlocillin, Baypen) and 5-methyl-3-phenyl-4-isoxazolylpenicillin (oxacillin, Stapenor), in 85%. Bacteria were eliminated in 79%.
