The efficacy of hypothermia in reducing ischemia-induced brain injury is very well described. However, the challenges for hypothermia-induced neuroprotection in the clinical setting include the best route of delivery (surface cooling or endovascular), the difficulties in patient management, and the potential secondary adverse events [18].

Mar 20, 2019 · OVERVIEW. The solubility of oxygen and carbon dioxide is increased at low temperatures. As a result, there is controversy about how arterial blood gases (ABG) should be interpreted in patients with altered body temperature, with hypothermia being most clinically relevant.

Jan 01, 1986 · Oxygen transport and delivery to peripheral tissues during hypothermia are analyzed theoretically, taking into consideration various conditions observed both in nature and clinically. With decreasing temperature, P 50 (the oxygen tension [P o 2 ] at 50% hemoglobin saturation with oxygen) decreases, thereby leading to low mixed venous oxygen ...Author: David C. Willford, Esther P.

Background. This study was undertaken to investigate the relations between whole body oxygen consumption (VO2), oxygen delivery (DO2), and hemodynamic variables during cardiopulmonary bypass.Methods. One hundred one patients were studied during cooling, hypothermia, and rewarming. Oxygen consumption, DO2, hemodynamics, and DO2crit were measured at these times.Results. …Author: Alessandro Parolari, Francesco Alamanni, Tiziano Gherli, Antonella Bertera, Luca Dainese, Cristina C...

When this occurs, oxygen delivery to subcutaneous tissues decreases impairing the strength of the collagen lattice that supports the healing scar[15,16]. Decreased oxygen delivery also impairs chemotaxis, phagocytosis, and antibody production by white blood cells and the immune system. In patients undergoing colorectal surgery, the last ...Author: Julie R McSwain, Maria Yared, John Wesley Doty, Sylvia H Wilson
