Selective head cooling and whole body cooling as neuroprotective agents in severe perinatal asphyxia

SUMMARY INTRODUCTION The possibility that hypothermia has a therapeutic role during or after resuscitation from severe perinatal asphyxia has been a longstanding focus of research. Studies designed around this fact have shown that moderate cerebral hypothermia, initiated as early as possible, has been a...

Hypothermia treatment ameliorated cyclin-dependent kinase 5-mediated inflammation in ischemic stroke and improved outcomes in ischemic stroke patients

Clinics; 74 (), 2019
OBJECTIVES: The inflammatory response is a key mechanism of neuronal damage and loss during acute ischemic stroke. Hypothermia has shown promise as a treatment for ischemic stroke. In this study, we investigated the molecular signaling pathways in ischemic stroke after hypothermia treatment. METHODS: Cy...

Topical hepatic hypothermia associated with ischemic preconditioning. Histopathological and biochemical analysis of ischemia reperfusion damage in a 24 hour model

Acta cir. bras; 33 (10), 2018
Abstract Purpose: To develop a new 24 hour extended liver ischemia and reperfusion (LIR) model analyzing the late biochemical and histopathological results of the isolated and combined application of recognized hepatoprotective mechanisms. In addition, we used a new stratification with zoning to classi...

Encefalopatía hipóxica-isquémica neonatal
Neonatal hypoxic-ischemic encephalopathy

Medicina (B.Aires); 78 (supl.2), 2018
La encefalopatía hipóxica-isquémica es un síndrome bien definido que afecta a los recién nacidos a término debido a asfixia fetal al nacer. La incidencia es 1-8 de cada 1000 nacidos en países desarrollados y asciende hasta 25 cada 1000 nacidos en países en desarrollo. Las causas más frecuentes s...

Efficacy of passive hypothermia and adverse events during transport of asphyxiated newborns according to the severity of hypoxic-ischemic encephalopathy

J. pediatr. (Rio J.); 94 (3), 2018
Abstract Objective To determine if the efficacy of passive hypothermia and adverse events during transport are related to the severity of neonatal hypoxic-ischemic encephalopathy. Methods This was a retrospective study of 67 infants with hypoxic-ischemic encephalopathy, born between April 2009 and Dece...

Effects of hypothermia on lung inflammation in a rat model of meconium aspiration syndrome

Acta cir. bras; 33 (6), 2018
Abstract Purpose: To evaluate the effects of hypothermia treatment on meconium-induced inflammation. Methods: Fifteen rats were instilled with human meconium (MEC, 1.5 mL/kg, 65 mg/mL) intratracheally and ventilated for 3 hours. Eight rats that were ventilated and not instilled with meconium served a...

Effects of remote ischemic preconditioning and topical hypothermia in renal ischemia-reperfusion injury in rats

Acta cir. bras; 33 (5), 2018
Abstract Purpose: To evaluate whether combining hypothermia and remote ischemic preconditioning (RIPC) results in protection from ischemia-reperfusion (IR). Methods: Thirty-two Wistar rats underwent right nephrectomy and were randomly assigned to four experimental protocols on the left kidney: warm isc...

Combined effects of melatonin and topical hypothermia on renal ischemia-reperfusion injury in rats

Acta cir. bras; 33 (3), 2018
Abstract Purpose: To evaluate whether their combination was more effective than either alone in decreasing renal damage due to ischemia/reperfusion (I/R) injury in rats. Methods: Thirty-two Wistar rats were assigned to four groups. Following right nephrectomy, their left kidneys were subjected to warm...

Application of a pharmacokinetics-pharmacodynamics approach to the free propofol plasma levels during coronary artery bypass grafting surgery with hypothermic cardiopulmonary bypass

Clinics; 73 (), 2018
OBJECTIVES: The objective of this study was to apply a pharmacokinetics-pharmacodynamics approach to investigate the free propofol plasma levels in patients undergoing coronary artery bypass grafting under hypothermic conditions compared with the off-pump procedure. METHODS: Nineteen patients scheduled ...
