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) diabetic rats. The aim of this study was to investigate whether the skin rewarming rate in diabetic rats is related to microvascular changes and wh...

Glycolysis, glucose oxidation, palmitate oxidation, and cardiac function were measured in isolated working hearts from ground squirrels and rats subjected to a hypothermia-rewarming protocol. Hearts were perfused initially for 30 min at 37 degrees C, followed by 2 h of hypothermic perfusion at 15 degrees C, after which hearts were rewarmed to 37 degrees C and further perfused for 30 min. Functi...

We studied relaxation during rapid rewarming of rabbit ventricular muscles that had been activated by rapid cooling. Rewarming from 1 degree to 30 degrees C (in less than 0.5 second) activates mechanisms that contribute to the reduction of intracellular calcium concentration and thus relaxation (e.g., sarcoplasmic reticulum [SR] calcium pump and sarcolemmal Na-Ca exchange and calcium pump). Rap...

BACKGROUND Patient rewarming after hypothermic cardiopulmonary bypass (CPB) has been linked to brain injury after cardiac surgery. In this study, we evaluated whether cooling and then rewarming of body temperature during CPB in adult patients is associated with alterations in cerebral blood flow (CBF)-blood pressure autoregulation. METHODS One hundred twenty-seven adult patients undergoing CP...

BACKGROUND Despite new improvements on cardiopulmonary resuscitation (CPR), brain damage is very often after resuscitation. OBJECTIVE To assess the prognostic value of cerebral oxygen saturation measurement (rSO2) for assessing prognosis on patients after cardiopulmonary resuscitation. DESIGN Retrospective analysis. MEASUREMENTS AND RESULTS We analyzed 25 post-CPR patients (12 female and ...

PURPOSE This study investigates the effects of room temperature on two standard tests used to assist the diagnosis of vibration-induced white finger (VWF): finger rewarming times and finger systolic blood pressures. METHODS Twelve healthy males and twelve healthy females participated in four sessions to obtain either finger skin temperatures (FSTs) during cooling and rewarming of the hand or ...

Thin unmounted cortical tissue sections from winter twigs of the mulberry tree were held with a thin forceps and rapidly immersed in liquid nitrogen from room temperatures without prefreezing. They were rewarmed; rapidly in water at 10 degrees to 40 degrees , or slowly, in air at room temperatures. In those sections rapidly rewarmed, all survived. None survived in those sections rewarmed slowly...

The use of extracorporeal membrane oxygenation is a new approach to rewarming patients with severe hypothermia and hemodynamic instability. There are, however, many questions regarding qualification for this technique in case of suspected or confirmed trauma.A male with confirmed accidental hypothermia (25°C) and after successful cardiopulmonary resuscitation from in-hospital cardiac arrest was...

Both the finger systolic blood pressure (FSP) and the rewarming test of finger skin are measures of circulation in the finger; the first reflects the vasoconstriction phase and the second the vasodilatation phase. The combinations of the specificity and the sensitivity of these methods were evaluated by a receiver operating characteristic curve (ROC). The material included 37 vibration-induced ...

BACKGROUND Postoperative hypothermia in children in postanesthesia care unit (PACU) is a well-known serious complication as it increases the risk of blood loss, wound infections, and cardiac arrhythmias. We conducted this prospective randomized controlled trial to evaluate the effect of an electric blanket plus a forced-air warming system on rewarming in children with postoperative hypothermia....
