[Reactive-periodical variations of vegetative parameters following orthopedic operations (author's transl)]

Continuous examinations during 4-6 weeks following various orthopedic operations of circulatory, retinuous improvement of the factors examined. E.g. frequency of resting pulse showed periodic variations with, in parts, regressive tendencies. In individual cases the maxima and minima of these variations showed considerable differences, but had a peak of frequency at 6-7 days. Similar variations of stabilizations of circulation were seen in 7 amputees of the lower limb, at rest and when learning to walk. Such variations with mainly circaseptan periodicity are unspecific accompanying reactions as part of vegetative adaptation, as known elsewhere. Similar investigations on 15 patients, walking after replacement of the hip joint and before the operation, are reported on. During the first 3-5 postoperative weeks circulatory findings were much worse, but 2 years later the values at rest and when walking were much improved, because of better walking economy.
