Objective(s): The aim of this study wasto investigate the effects of mild hypothermia therapy on oxidative stress injury of rabbit brain tissue after cardiopulmonary resuscitation (CPR). Materials and Methods: Rabbit models of cardiac arrest were established. After the restoration of spontaneous circulation, 50 rabbits were randomly divided into normothermia and hypothermia groups. The followi...
Background: Hypothermia is an important determinant of survival in newborns, especially among low-birth-weight ones. Prolonged hypothermia leads to edema, generalized hemorrhage, jaundice and ultimately death. This study was undertaken to examine the factors affecting transition from hypothermic state in neonates.Methods: The study consisted of 439 neonates hospitalized in NICU of Valiasr i...
Aim and Background: hypothermia is a common complication in surgeries patients and may have serious consequences in both mother and fetal in cesarean surgery. This study was implemented to assess the effect of intravenous (IV) infusion of warm fluids on decreasing hypothermia in mothers and its consequences on ne...
objective(s):to investigate the effects of local mild hypothermia on the expression of fas, fasl and mmp-3 after cerebral ischemia-reperfusion in rats. materials and methods:male wistar rats were divided into sham-operated group (sham), normothermia group (nt), and hypothermia group (ht). mcao/r model was established by longa’s method, and reperfusion was allowed after 2 hr occlusion. mild hypo...
the effects of cholecystokinin (cck) receptor antagonists on hypothermia induced by cocaine or morphine have been studied in mice. in the present work, subcutaneous (sc) injection of cocaine (50-150 mg/kg) or morphine (125-500 mg/kg) induced hypothermia in mice. administration of ccka receptor antagonist mk-329 (0.5-1.5 mg/kg), cckb receptor antagonist l-365, 260 (0.5-1.5 mgl kg) and cck recept...
Accidental hypothermia is associated with increased risk for arrhythmias. QRS/QTc proposed as an ECG-marker, where decreasing values predict hypothermia-induced ventricular If reliable it should also nonappearance of arrhythmias, observed in species like rat that regularly tolerate prolonged hypothermia. A model designed studying cardiovascular function during cooling, and subsequent rewarming ...
Introduction: Maintenance of the body temperature reduces mortality in low birth weight infants and adequate environmental warmth is essential for maintenance of the body temperature of newborns. However, neonatal hypothermia continues to be a significant issue in the developing countries. This study was performed to describe the incidence and severity of hypothermia after delivery. Materials a...
abstract background: in 1958, silverman demonstrated that maintenance ofbody temperature reduces mortality in low birth weight infants. from the early 1990s it was already recognized that adequate environmental warmth was essential in the case of newborns. however, neonatal hypothermia continues to be a significant issue in developing countries. methods: in order to describe the incidence and s...
Background: Neonatal deaths mostly occur within the first one week and first 24 hours of life from a variety of conditions. Objective: To examine the role of significant hypothermia and hypoglycaemia, in addition to some other factors, in neonatal mortality occurring within the first 24 hours of admission.Methods: A prospective study of newborn infants hospitalized within the first 24 hours of ...
Hypothermia in nature occurs in hibernating animals. It has applications in medicine in open heart surgery,organ and connective tissue preserving, altitude medicine and geriatrics. Despite the vastness of studies on hypothermia many of its biologic and physiologic effects including endocrine system alterations are still poorly recognized. In this study the effect of hyp...
