title: [The influence of surgery upon leucocyte function (author's transl)].
abstract: 14 patients who underwent a standardized total hip joint replacement were investigated in order to detect postoperative impairment of chemotactic or phagocytic function of their polymorphonuclear leucocytes. A chemotaxis assay in modified Boyden [3] chambers and the nitroblue-tetrazolium assay were used. 25 healthy control persons served for the assessment of normal values and the reproducibility of the respective test. Patients were investigated preoperatively and on the first, third and sixth postoperative day. While phagocytosis remained unchanged throughout the period of investigation, chemotactic leucocyte function was regularly significantly depressed on the first postoperative day. The defect in postoperative chemotaxis might, despite of an unimpaired phagocytic capacity, contribute towards an increased risk of postoperative infections.
