Filter by:An important goal of haemodynamic monitoring and resuscitation is early detection of insufficient tissue perfusion and oxygenation. The mesenteric haemodynamic response to circulatory shock is complex, and diagnosis of bowel ischaemia poses significant difficulty. Assuming blood flow is diverted from the peripheral tissue and the gastrointestinal tract to vital organs, during circulatory shock, an objective, simple and non-invasive method of detecting peripheral tissue perfusion impairment might detect this at an early stage. The peripheral perfusion index (PPI) reflects changes in peripheral perfusion and laser doppler flowmetry allows measurement of bowel tissue perfusion. The aim of this study is to explore the association between changes in peripheral and intestinal perfusion in patients undergoing elective colorectal surgery exposed to intraoperative haemodynamic challenges.
