A Device for Studying Hemocirculation in Suture Bands in Interintestinal Anastomoses

摘要

A device for investigating blood pressure in the intramural vessels of hollow organs and determining arterial blood hemoglobin oxygen saturation was developed; the device consists of two chambers, one containing LED lamps and the second, an emitter for determining blood oxygen saturation. The problem of inadequacy of sutures used in interintestinal anastomoses remains current [1,2], All investigators agree with the view that the interintestinal anastomosis zone must have a viable hemocirculation after intestinal resection. Laser Doppler flowmetry, angiotensometry as described by Sigal [3-5], pulsomotorography as described by Sigal [6], redoxometry [7], and electromyography [8] are currently used for assessing the blood circulation in suture bands after intestinal resection and formation of interintestinal anastomoses. However, suture inadequacy after use of these approaches and devices for assessing the blood circulation in suture bands after intestinal resection and formation of interintestinal anastomoses has been demonstrated [1,3, 4,6-9]. Thus, the development of new device for intraopera-tive assessment of the viability of the suture band of the intestine on formation of interintestinal anastomoses is also a relevant challenge. The aim of the present work was to develop a new device for assessment of the blood circulation in suture bands in the intestine. The study addressed the following tasks: 1) to develop a new device for assessing the blood circulation in suture bands in the intestine on formation of interintestinal anastomoses; 2) experimental clinical testing of the new device to study blood pressure in intramural vessels in suture bands in the intestine and oxygen saturation of arterial blood hemoglobin.
