A prospective study of postoperative infectious complications after open-heart surgery was carried out in 885 @entity1 . @entity86 occurred in 173 @entity1 , an overall incidence was 19.5%. The mortality rate was 0.8%. The incidence of sternal wound @entity281 was 7.7% (superficial 6.3% and deep 1.4%) and of leg wound @entity281 11.4%. Superficial sternal wound @entity281 were associated with @entity295 in 10.7% and deep sternal wound @entity281 in 33.3%. The leg wound @entity281 caused no blood culture positive @entity295 . The incidence of @entity293 was 4.6% while respiratory tract @entity281 occurred in only 2.5%. Early prosthetic @entity340 occurred in only one @entity1 (0.3%). @entity794 and epidermidis were the two bacteria most frequently cultured from sternal wound @entity281 (82.4%), while gram-negative bacteria alone were seldom found (5.9%). In leg wound @entity281 the incidence of gram-negative bacteria was greater (17.3%). Although @entity526 was the causative agent in 37% of postoperative @entity293 the incidence of @entity281 by the classical hospital-acquired organisms (klebsiella and @entity2782 ) was also high (32%). @entity86 caused an average prolongation of hospital stay of 8 days. The increase was shortest for @entity293 (5 days) and longest in @entity1 with postoperative @entity1764 (28 days).
