The effect of patient positions on perfusion index

Abstract Background The optimal position for surgery is one in which the patient is provided the best possible surgical intervention and put at minimum risk. Different surgical positions may cause changes in tissue perfusion. This study investigates the relationship between surgical patient positions and perfusion index. Methods A sample of 61 healthy individuals with no peripheral circulatory disorders, chronic diseases, or anemia was included in this study. Participants held six different positions: supine, prone, 45-degree sitting-supine, 45-degree supine with legs lifted, Trendelenburg (45-degrees head down), and reverse Trendelenburg (45-degrees head up). Perfusion index values were then measured and recorded after individuals held their positions for five minutes. Results Participants’ perfusion index values were affected by different body positions (p < 0.05). Perfusion index was lowest in the sitting position (4.5 ± 2.5) and highest in individuals with Trendelenburg position (7.8 ± 3.8). Conclusion Different body positions can cause changes in tissue perfusion. This should be considered in patient follow-up along with the perfusion index

Comparisons of microbiota-generated metabolites in patients with young and elderly acute coronary syndrome

Objective: Acute coronary syndrome (ACS) is a leading cause of death worldwide. There is great interest in defining the risk factors and underlying mechanisms of ACS among young people. The microbiota and its metabolites have recently become a popular research topic, yet there is still no study that investigated microbiota-generated metabolites as a possible risk factor in young patients with ACS. In this study, we aimed to investigate the relationship between microbiota-generated metabolites and ACS in young people

An investigation of the relationship between arterial aortic stiffness and coronary slow flow that was detected during coronary angiography

Aim Increased intimal thickness in coronary arteries, extensive calcification, and atheromatous plaque that does not cause luminal irregularities in a significant portion of the patients with coronary slow flow (CSF). Arterial stiffness is an indicator for atherosclerosis. We aimed to investigate the relation between coronary slow flow phenomenon (CSFP) and arterial stiffness
