Filter by:Although data on cardioprotective effects (as profile of troponin I)of perioperative maintenance of normothermia during CABGs are already known, little is known about the effects of maintaining normothermia on clinical outcomes of patients submitted to coronary surgery. Being acute renal failure (ARF) and atrial fibrillation (AF) the two most frequent complications of this surgery, this study compare as primary end point the rate of postoperative ARF and AF in two group of patients, one actively warmed with Thermowrap and the control group receiving standard institutional care.
Bacterial meningitis is a severe infection of the envelope which surrounds the brain. It is sometimes responsible for a cerebral oedema mattering with a loss of consciousness (coma). The usual treatment of this affection is based on the antibiotic therapy, anti-inflammatory drug and resuscitation measures in intensive care setting but the prognosis of comatose patients remains poor. Moderate hypothermia (body temperature is downed between 32 and 34°C°) made the proof of its efficiency in certain cerebral pathologies (notably the cerebral distress after cardiac arrest or oxygen lack in neonates) but was never evaluated in meningitis. In meningitis animal studies and in severe traumatic brain injury, moderate hypothermia is able to diminish cerebral oedema and brain inflammation. Thus, the objective of this study is to compare two strategies: only usual care or usual care completed by moderate hypothermia. The body temperature will be lowered between 32 and 34°C by means of a catheter placed in a big vein and connected to a machine in which circulates a cold liquid, or by means of an external cooling (ice-cold blanket, ice packs placed on the body). Whatever technique is chosen, the technique is perfectly mastered by the teams which take charge of the patients. After 48 hours, the technique of hypothermia will be suspended and body temperature will return passively and gradually to normal. The investigators believe that moderate hypothermia will improve the prognosis of the most severe patients.
Two patient warming systems will be compared with 40 patients each in a convective warming group (BairHugger, Arizant) and in a conductive warming group (HotDog, Augustine Biomedical). The patients will undergo small to medium trauma surgery and will be warmed with the randomized device - the hypothesis is, that the area under the standardized core temperature / time curve is significantly greater in the conductive warming group. Secondary outcome is the mean skin temperature / time area under the curve.
Incidence of hypo- and hypercarbia during induced hypothermia after cardiac arrest is high. The original report from HACA-group reported that hypothermia treated patients had improved survival and neurological outcome. Suprisingly, in that trial normocarbia was not achieved even though the aim was set for ventilatory support as normoventilation. This study aims to investigate the effects of mild hypo- and hypercarbia on cerebral perfusion (blood flow, intracranial pressure) and metabolism (microdialysate metabolites). We hypothesize that uncontrolled ventilatory suppport may render the patients in risk of exacerbation of neuronal damage, conversely, further improvement in outcome may be achieved with succesfull ventilatory management. We intend to enroll 10 out-of-hospital cardiac arrest patients succesfully resuscitated and subsequently treated with controlled hypothermia for 24 hours. The patients in need of anticoagulation are excluded. We plan to induce mild hypocarbia and hypercarbia during and after induced hypothermia. Metabolic and perfusion data are collected with clinically used methods such as transcranial doppler, intracranial pressure measurement, near infrared spectroscopy, jugular bulb, intracerebral microdialysis).
The hypothesis of this study is that consciously sedated patients suffering from ST-elevation myocardial infarction can be rapidly and safely cooled to a state of therapeutic hypothermia (32 to 34 degrees C) using the LRS ThermoSuit System prior to percutaneous coronary intervention.
The investigators hypothesized that, following cardiac arrest in pediatric patients, hypothermia therapy will improve the proportion of patients with a good functional outcome compared to a normothermic control group.
The purpose of this study is to determine whether a custom-made forced-air warming mattress can prevent heat loss in patients undergoing vascular surgery better than a circulating-water mattress
We aim that uncovering patients during induction of general anesthesia does not decrease core body temperature in pediatric patients.
Therapeutic hypothermia has been shown to improve survival and neurologic outcome in patients resuscitated after ventricular fibrillation arrest. Few studies have examined whether therapeutic hypothermia is effective outside the research setting, or with other presenting rhythms. Our institution, a large community teaching hospital, instituted a therapeutic hypothermia protocol in November 2006 for all resuscitated cardiac arrest patients. The investigators seek to determine the mortality rate of our protocol and compare our complication rates with those of previously published studies.
The primary goal of this project is to demonstrate the feasibility and clinical benefits of a new rapid treatment for secondary treatment for secondary brain injury called Discrete Cerebral Hypothermia System by CoolSystems, Inc., Berkley, CA. This device induced hypothermia in the adult brain without significant whole body hypothermia. Discrete Cerebral Hypothermia System holds a great potential for protecting the brain from the devastating secondary complications of trauma without the associated deleterious system effects.
