Standardization for obtaining blood viscosity: A systematic review

Abstract

Introduction There is evidence to suggest that blood viscosity (BV) is involved in several pathological processes. In this review, we evaluated the different methods of BV acquisition, analyzing the sample storage time, the storage temperature, the acquisition time, the acquisition temperature, sample volume, and shear rates, in order to standardize this technique. Methods We selected 50 articles with methods of obtaining BV, evaluating pathologies through BV, comparing rheological equipment, monitoring, and regulating BV. Results and conclusion Measurements should be obtained as soon as possible, to reduce hemorheological changes. It is necessary to refrigerate them at 4°C when the storage time is long. The acquisition time is related to the equipment used. BV measurements at 37°C will represent the real BV in vivo more faithfully. In order to understand the BV phenomena, the shear rates must be between 0.1 and 1000 s‐1. There is a wide variety of equipment available for measuring the BV.

Exact Association Between Preoperative Blood Viscosity and Postoperative Deep Venous Thrombosis Risk in Knee Osteoarthritis Patients: A 10-Year Retrospective Study

“…In this regard, the change law of BV can provide useful data for the diagnosis, treatment, and prognosis of some arterial vascular diseases. 19 To the authors’ knowledge, few researches have paid attention to the correlation between the specific change rule and/or amplitude of BV-related parameters and DVT. We herein prompted that the rapid increase of BRV may actually affect DVT in such patients and the occurrence of low BRV before surgery can potentially be considered as an implication of thrombophilia.…”

Effectiveness and Safety of Fufang Danshen Dripping Pill (Cardiotonic Pill) on Blood Viscosity and Hemorheological Factors for Cardiovascular Event Prevention in Patients with Type 2 Diabetes Mellitus: Systematic Review and Meta-Analysis

“…For the confirmation of blood viscosity, the cone plate rotation and scanning capillary methods were considered representative. The cone plate rotation method is a technique that measures the blood resistance when a certain amount of blood is put between the cone and the plate and rotated, and converts it into blood viscosity [27]. In the case of the scanning capillary method, the blood is passed through an Ethylenediaminetetraacetic acid (EDTA) tube and the viscosity of the blood is measured.…”

Interdependence of Rheological and Biochemical Parameters of Blood in a Group of Patients with Clinically Silent Multifocal Vascular Cerebral Lesions

“…Blood viscosity has been studied in many research centers and among many different groups of patients. The main disorders related to the hemorheological properties are coronary insufficiency, vascular congestion, myocardial infarction, a cerebral circulation disorder, Reynaud disease, ischemic limbs, diabetes, anemia, and tumors [5,7,8,15,16,21].…”
