Active clinical trials for "Hypothermia"

This study is designed as a multicenter, randomized, assessor- blinded clinical trial.The primary aim of this trial is to assess whether retrograde inferior venal caval perfusion combined selective antegrade cerebral perfusion(ACP)under mild hypothermia, compared with moderate hypothermia combined with selective ACP alone, improves the outcome for the patients undergoing total aortic arch replacement.

Researchers are proposing a pilot randomized controlled trial evaluating the benefit of immediately warming preterm babies using a warming mattress and a plastic wrap, while delaying clamping the umbilical cord at the time of c-section in babies born between 32 and 36 weeks to determine if it reduces the risk of hypothermia.

Cardiac arrest is at present a major cause of mortality as well as a cause of disability for the surviving victims.In Europe, every year counts as 300,000 cardiac arrests responsible for 250,000 deaths. Thus, less than 20 % of patients discharged home with impaired quality of life associated with symptoms of tiredness, stress, anxiety. The prognosis is related to the initial cardiac rhythm present during the initiation of resuscitation. Recent progress in the improvement of mortality and neurological outcome has been achieved over the last decade thanks to the systematic implementation of a period of targeted temperature control between 32 and 34 ° C in patients who benefited from the realization of at least one electrical external shock. There are theoretical and clinical arguments to think that achieving the same way a period of targeted temperature control between 32 and 34 ° C in patients treated for cardiac arrest with a non- shockable rhythm on arrival can also benefit from this procedure. However other arguments are against this hypothesis including an increase in the risk of infection , worsening of the patient's hemodynamic status with no benefit to him. To answer this question, we conduce a randomized multicenter study testing the potential improvement of neurological outcome through this procedure targeted temperature control between 32.5 and 33.5 ° C in these patients. NSE-Ancillary Study of HYPERION Trial will determine impact on neurospecific enolase (brain biomarker) of two temperature target for targeted temperature management (33°C or 37°C) after cardiac arrest in non-shockable rhythm.

In this study two warming methods will be compared in knee arthroplasty surgery. Barrier EasyWarm will be used in the study group and BairHugger upper body warming blanket in the control group. Both groups will be prewarmed 30 minutes before spinal anaesthesia. In the operating room warming will be continued with the same warming method. Primary end point is core temperature after arriving to post anaesthesia care unit. Hypothesis is that Barrier EasyWarm is not inferior to BairHugger in preventing inadvertent intraoperative hypothermia. Few methods exist to measure the core temperature non-invasively. Zero-heat-flux technique is used in this study. During the study we will test the accuracy of the 3M BairHugger Temperature Monitoring System by placing two sensors onto the patients (n = 30) fore head. After that the accuracy of the Dräger Tcore is examined by comparing it with the 3M BairHugger Temperature Monitoring System. So the patients (n=30) have both these different core temperature monitoring systems on their foreheads. This observational monitoring study is performed from the patient number 80 until the end.

Cardiac arrest is a leading cause of sudden death, but the survival rate of cardiac arrest is only 5-35%. Although, the first resuscitation of cardiac arrest patient would be success, the hypoxic brain injury after cardiac arrest is an important cause of the mortality and the morbidity. For the management of the hypoxic brain injury after cardiac arrest, American Heart Association and European Resuscitation Council recommend induced mild hypothermia therapy. And, ILCOR(International Liaison Committee on Resuscitation) announced the standard treatment of post cardiac arrest syndrome(the success state of first resuscitation of the cardiac arrest patient) included the induced mild hypothermia therapy at September, 2008. The generalized seizure and myoclonus arise in over 60% of post cardiac arrest syndrome patients and they are very difficult to control. Also, the occurrence of them implies poor prognosis of the patient. Although, mild hypothermia therapy could be decrease the development and propagation of generalized seizure and myoclonus theologically, the therapy could not prevent the development and propagation of them entirely. Therefore, the use of prophylactic anticonvulsant should be needed. But, there is not randomized control study about the use of prophylactic anticonvulsant. We hypothesized that the use of prophylactic anticonvulsant to post cardiac arrest syndrome patients would decrease the rate of occurrence of generalized seizure and myoclonus and would improve the neurologic outcome. We planed that we used two anti-epileptic drugs - valproate, clonazepam - for the prophylactic anticonvulsant. The valproate and clonazepam are in general use for prevention and treatment of generalized seizure and myoclonus and are recommended to treat of generalized seizure and myoclonus to post cardiac arrest syndrome patients by 2008 guideline of ILCOR.

To study, with a prospective randomised controlled design, whether the subcutaneous administration of the haemostatic drug desmopressin, may improve the impairment of primary haemostasis due to mildly decreased temperature.

The overall hypothesis is that better adherence to Kangaroo Mother Care (KMC) in combination with existing WHO thermoregulation care will reduce the incidence of moderate hypothermia (32-36 degrees C) or severe hypothermia (<32.0 degrees C) in preterm infants (32-36 6/7 weeks of gestational age) when compared with routine WHO thermoregulation alone.

Studying the feasibility of an initial sedation with inhalated sevoflurane during therapeutic hypothermia of cardiac arrests resuscitated patients.

This is a sub-study to the Time-differentiated Therapeutic Hypothermia (TTH48, ClinicalTrials.gov Identifier: NCT01689077). TTH48 compares 24 with 48 hours of therapeutic hypothermia at a target temperature of 32-34°C in survivors of out-of-hospital cardiac arrest. The overall aim of this sub-study is to examine the hemostasis in patients resuscitated after cardiac arrest and treated with 24 and 48 hours of therapeutic hypothermia Our specific aims are: To investigate the whole blood coagulation using the rotational thromboelastometry. To investigate the function of platelets

The majority of women (> 60%) developed hypothermia and shivering during cesarean delivery. Core hypothermia may be associated with a number of adverse outcomes in patients, including shivering, wound infection, coagulopathy, increased blood loss and transfusion requirements, decreased metabolism and prolonged recovery. Shivering can result in interference with monitoring, increased tension on wound edges, and increased oxygen consumption. A previous study has shown several modalities to prevent hypothermia and shivering in patients undergoing cesarean delivery with spinal anesthesia. But, single modality intervention have shown marginal or no efficacy. Neuraxial anesthesia reduces the threshold for vasoconstriction and shivering. It often also produces a lower body sympathectomy that provokes a core to peripheral redistribution of body heat. It is difficult to treat the core to peripheral redistribution of body heat. However redistribution can be prevented by preanesthetic cutaneous warming. Prewarming hardly changes core temperature that remains well regulated, but it markedly increases peripheral tissue heat content. As a result, prewarming reduces the core to peripheral tissue temperature gradient and the propensity for redistribution after the induction of anesthesia. We therefore hypothesized that Combined modality active warming consisting of preoperative 15 min of surface warming using a forced air warmer before spinal anesthesia and coloading of warmed intravenous fluid might reduce perioperative hypothermia and shivering in women undergoing cesarean delivery. Additionally, We tested the hypothesis that maintaining maternal normothermia increases newborn temperature and Apgar scores.
