Venous Blood Volume

Position of a patient in surgical procedures, clinical examinations is an important assisting factor. Position of patient in minor and major surgical procedures is mentioned in ayurveda as well as modern surgery. One of such position is mentioned in Sushrut samhita sharirsthan chapter 8 and shloka number 8. This reference is about siraa utthaan before siravedh / venepuncture / bloodletting procedure. Before this procedure a position is given to patient by doctor. This study is about review of physiological changes in venous blood flow due to position of legs, use of bandhan [like tourniquet], location of bandhan from venepuncture site and effect of these techniques on veins and venous blood volume. Vein should be prominent and full of blood [sira utthaan] i.e., expected before bloodletting treatments/procedures.

Abstract Background During pregnancy, a number of changes affecting venous blood flow occur in the circulatory system, such as reduced vein wall tension or increased exposure to collagen fibers. These factors may cause blood stagnation, swelling of the legs, or endothelial damage and consequently lead to development of venous disease. Objectives The aim of this study is to evaluate the effect of special footwear designed to improve blood circulation in the feet on venous blood flow changes observed during advancing phases of pregnancy. Methods Thirty healthy pregnant women participated in this study at 25, 30, and 35 weeks of gestation. Participants were allocated at random to an experimental group (n = 15) which was provided with the special footwear, or a control group (n = 15). At each data collection session, Doppler measurements of peak systolic blood flow velocity and cross-sectional area of the right popliteal vein were performed using a MySonoU6 ultrasound machine with a linear transducer (Samsung Medison). The differences were compared using Cohen’s d test to calculate effect size. Results With advancing phases of pregnancy, peak systolic velocity in the popliteal vein decreased significantly in the control group, whereas it increased significantly in the experimental group. No significant change in cross-sectional area was observed in any of the groups. Conclusions Findings in the experimental group demonstrated that wearing the footwear tested may prevent venous blood velocity from reducing during advanced phases of pregnancy. Nevertheless, there is a need for further investigation of the beneficial effect on venous flow of the footwear tested and its application.
