Cerebrovascular reactivity during hypothermia and rewarming [PDF]

British Journal of Anaesthesia, 2007
Experimental evidence from a murine model of traumatic brain injury (TBI) suggests that hypothermia followed by fast rewarming may damage cerebral microcirculation. The effects of hypothermia and subsequent rewarming on cerebral vasoreactivity in human TBI are unknown.This is a retrospective analysis of data acquired during a prospective, observational

Variability in peripheral rewarming after cold stress among 255 healthy Norwegian army conscripts assessed by dynamic infrared thermography

International Journal of Circumpolar Health, 2018
Exposure to cold climate is an inevitable consequence of military training in Norway. Adequate peripheral microcirculation in the extremities is important to maintain temperature, and to protect against freezing cold injuries.

Gradual rewarming with a hemoglobin-based oxygen carrier improves viability of donation after circulatory death in rat livers [PDF]

Frontiers in Transplantation
BackgroundDonation after circulatory death (DCD) grafts are vital for increasing available donor organs. Gradual rewarming during machine perfusion has proven effective in mitigating reperfusion injury and enhancing graft quality.

Occupational cold stress and rewarming alters skin temperature thresholds for manual dexterity decrements: An exploratory study [PDF]

Physiological Reports
The skin temperature thresholds at which precipitous reductions in dexterity occur in cold environments, and whether they are altered by rewarming, are not well defined. In three environmental conditions (20°C, 10°C, and 0°C air temperatures), 14 healthy

An early diagnostic tool for diabetic peripheral neuropathy in rats. [PDF]

PLoS ONE, 2015
The skin's rewarming rate of diabetic patients is used as a diagnostic tool for early diagnosis of diabetic neuropathy. At present, the relationship between microvascular changes in the skin and diabetic neuropathy is unclear in streptozotocin (STZ ...

Controlled oxygenated rewarming as novel end‐ischemic therapy for cold stored liver grafts. A randomized controlled trial

Clinical and Translational Science, 2022
Abrupt return to normothermia has been shown a genuine factor contributing to graft dysfunction after transplantation. This study tested the concept to mitigate reperfusion injury of liver grafts by gentle warming‐up using ex vivo machine perfusion prior

Prolonged Controlled Oxygenated Rewarming Improves Immediate Tubular Function and Energetic Recovery of Porcine Kidneys During Normothermic Machine Perfusion

Transplantation, 2022
Background. Normothermic machine perfusion (NMP) is typically performed after a period of hypothermic preservation, which exposes the kidney to an abrupt increase in temperature and intravascular pressure.

Vitrification and Rewarming of Magnetic Nanoparticle-Loaded Rat Hearts

Advanced Materials & Technologies, 2021
To extend the preservation of donor hearts beyond the current 4–6 h, this paper explores heart cryopreservation by vitrification—cryogenic storage in a glass‐like state. While organ vitrification is made possible by using cryoprotective agents (CPA) that

Enhanced Blood Clotting After Rewarming From Experimental Hypothermia in an Intact Porcine Model

Frontiers in Physiology, 2022
Introduction: Due to functional alterations of blood platelets and coagulation enzymes at low temperatures, excessive bleeding is a well-recognized complication in victims of accidental hypothermia and may present a great clinical challenge.

Rewarming From Hypothermic Cardiac Arrest Applying Extracorporeal Life Support: A Systematic Review and Meta-Analysis

Frontiers in Medicine, 2021
Introduction: This systematic review and meta-analysis aims at comparing outcomes of rewarming after accidental hypothermic cardiac arrest (HCA) with cardiopulmonary bypass (CPB) or/and extracorporeal membrane oxygenation (ECMO).
