[Large surgical flaps in the reconstruction of soft tissues after complicated injuries of the lower leg].

Experiences and results with a so called extended flap transfer including the fascia of the donor leg are discussed. Six patients suffering from complete open fractures of the lower legs underwent this procedure. All patients gained a functional and useful lower extremity. Also late reconstructive operations to cure bony problems did not affect detrimentally the healed flaps.

[Remarks and thoughts on the evaluation of results in replantation surgery].

In order to completely evaluate the results after replantation or revascularization of an amputated part, an additional factor, integration or the adaptation of the replanted part to the activities of daily living and to the occupational life of the patient, should be considered. Six categories are developed and illustrated with examples. Each of the categories is assigned a high differential multiplication factor according to whether the replanted part is useless (factor 1), not useful but also not a hindrance (factor 10), is only an aid to the healthy extremity (factor 30) or is of limited use in daily life and at work (factor 50). Factor 70 is assigned when the amputated part can be used with retraining in another job and is not a hindrance in daily life. Factor 100 applies when the replanted part does not interfere with daily living or occupation. This factor should be regarded as a supplementary assessment which attempts to objectively evaluate a replanted or revascularized part of the hand.

[Effect of a 3.6 o/o dextran Ringer acetate solution on moderately hypovolemic patients in intensive care].

The effects of 1000 ml 3.6% dextran Ringer's acetate solution (Mw 61,800; infusion time 60 min) on circulation, blood and plasma volume, blood viscosity and renal function parameters were investigated, the renal elimination of dextran also being measured. During the entire investigation period no significant alterations of cardiocirculatory parameters, blood and plasma volume and rheological properties of blood could be demonstrated, the same holding true for kidney function values. Dextran excretion was about 33% three hours after the end of infusion, reaching 51% of the whole amount given 21 hours later. It has to be assumed that mainly macromolecular dextran components of less efficiency are retained intravascularly. Taking into consideration the practically absent volume expanding effect - even at the end of infusion period - this dextran solution cannot be recommended as a blood substitute during acute hemorrhage or as an "expander" in other shock states.
