title: Bacterial contamination of pulmonary artery catheters.
abstract: The catheter tips of 152 patients, who were haemodynamically supervised by pulmonary artery monitoring or continuous cardiac output determination, were bacteriologically examined. 106 cultures remained sterile, 21 cultures revealed a growth of non pathogenic organisms. Staphylococcus aureus was cultured 15 times, pseudomonas aeruginosa 4 times, Citrobacter as well as Escherichia coli twice, and Klebsiella and Enterobacter once each. There was no statistically significant connection between dwelling period and contamination. Also diabetes mellitus or corticoid medication in high dosage had no significant influence on contamination rate.
