[Local antiseptics in surgery--rebirth and advances].

The history of antisepsis is marked by names such as Pringle, Lister, Billroth, Koch, Kocher, von Volkmann, von Nussbaum, Schloffer and Carrel. The revolutionary initial success of Lister's method was followed by severe setbacks because persisting biological intolerance of the chemical and physical antiseptics prevented the main purpose of application: killing bacteria without damaging cells. Until the discovery of penicillin the predominantly used antiseptics were perubalsam (balsamum peruvianum), azo-dyes (Rivanol), and sulphonamides (Cibazol). The dawn of the "antibiotic age" demonstrated once more the limits of locally applied therapeutic effectiveness of these substances (antiseptics, antibiotics) and was often outweighed by the damage caused. For the same reason systemicly applied substances frequently lack satisfactory effectiveness in the area of tissue damage. Experiences with intraoperative and postoperative wound lavage have shown that favourable results achieved by this surgical procedure are more likely due to the mechanical cleaning process than to the effectiveness of the locally applied substances being limited by the restricted duration of influence and the restricted depth of tissue penetration. Taking into account earlier studies and long-term experiences, antiseptic solutions were tested in view of their tissue compatibility, their biologic availability, and their effectiveness in close cooperation of clinic, bacteriology and laboratory medicine. The coordinated investigations resulted in a solution of biguanid (Lavasept) which is free from iodine, quicksilver, PVP and aldehyde. It can be applied for local treatment of wounds liable to infection, as an adjuvant for wound treatment in cases of acute tissue infections, as well as in the surgival practise to take care of acute and chronic infections of soft tissue. Sofar locally applied antiseptics in surgery have proved to be less satisfactory than considered in the course of their history due to side effects, e.g. tissue damage. Coordinated investigations now present an antiseptic solution of biguanid which can be used in various cases of wound treatment to prevent or counteract infections.

[Treatment tactics and late results in early infection following osteosynthesis].

UNLABELLED: On the basis of long term results (five to 29 years), the treatment of postoperative wound infection after internal fixation (40 shaft fractures) is outlined. Of decisive importance is the immediate surgical intervention as soon as the first clinical signs of infection become evident. PROCEDURE: opening of the wound, leaving stable implants in situ, temporary irrigation drainage. RESULTS: in 31 cases spontaneous bone healing without bone grafting. Only in nine cases a residual infected focus needed cancellous bone grafting (in five of these cases additional surgical stabilisation, in the other four cases the bone itself was already sufficiently stable). In 35 patients full restoration of working capacity; in 33 patients full functional repair.

[Malignant degeneration of fistulas in chronic osteomyelitis (author's transl)].

The malignant degeneration of a skin ulcer has been reported as early as in 1884. In spite of this, however, the danger of malignant degeneration of sinus tracts associated with recurrences of chronic osteomyelitis is still underestimated. This development is neither restricted to case histories of years and decenniums nor to elderly patients and may also involve any part of the skeleton. Usually patients become aware of suddenly increasing tenderness and purulation, "washed out" structures of osteolytic areas are demonstrable radiographically. Diagnosis is established by mandatory histological examination of sinus tracts. Amputation or exarticulation of the extremity involved including efferent lymphatic vessels and nodi has no alternative. Local measures are insufficient. Apparently the first 3 years are decisive as to the prognosis. The prophylaxis consists of the therapy of the original disease: radical debridement of the osteomyelitic focus and filling of the defect with autogenous cancellous bone grafts.
