Abstract
With in situ bone vital microscopy it was demonstrated that a cuff pressure of 300 mm Hg applied over the rabbit thigh is sufficient to cause a complete vascular standstill in the tibial cortex. Cuff-induced tissue ischemia applied for 30 min did not result in any adverse bone tissue reactions over a follow-up period of 30 days. Locally applied isolated bone ischemia for 3 or 6 h resulted in an inflammatory response, and 4–6 weeks after the 6-h ischemia bone resorption was evident. Anhand einer in situ ausgeführten Knochen-Vital-Mikroskopie konnte bewiesen werden, daß ein auf den Kaninchenschenkel ausgeübter Manschettendruck von 300 mm Hg ausreicht, um einen vollkommenen vaskularen Stillstand in der Tibia-Rinde zu verursachen. Eine über 30 min durch Manschette herbeigeführte Ischaemie des Gewebes zeigte während einer Beobachtungszeit von 30 Tagen keinerlei entgegenwirkende Reaktion im Knochengewebe. Lokal verursachte isolierte drei- bzw. sechsstündige Knochen-Ischaemie zeigte Entzündungsprozesse. Bei der sechsstündigen Ischaemie wurde nach 4–6 Wochen eine Knochen-Resorption offensichtlich.Keywords
