Active clinical trials for "Hypothermia"

Each year, only one third of patients registered on the waiting list receive a kidney transplant. Numerous paths are being explored with the aim of reversing this shortage. The first is to increase the number of organs by developing harvesting from donors in a state of brain-death (BD) termed "expanded criteria donors" or from patients deceased from circulatory arrest. Another fundamental factor is to insure the success of the transplant by limiting the dysfunction of donor kidneys, marked by a delayed graft function (DFG). The development of techniques to insure correct perfusion of harvested organs, and the optimization of reanimation and intensive care of brain-dead donors constitute important factors in DGF reduction. Therapeutic Hypothermia could to be an attractive care strategy for BD patients.

Controlled Hypothermia has become the standard of care for neonates with moderate to severe HIE. Ampicillin and aminoglycosides are drugs that are universally used for the treatment of suspected neonatal sepsis, which may or may not be responsible for the etiology of HIE. Currently, medication dosage regimens are not altered in the setting of CH. A better understanding of the effects of our interventions on this unique population may help us tailor our therapy to the specific circumstances of the patient

Perioperative hypothermia brings numerous and recognized postoperative complications. Active warming intraoperatively helps to maintain body temperature in the postoperative period, but there are few studies in Brazil, assessing the effect of prewarming in maintaining normothermia. It is believed that prewarming with forced air warming system keep the body temperature during intra and post-operative. This study aims to evaluate the effect on prewarming maintaining body temperature of patients undergoing elective surgery of Gynecology specialty using the forced air warming system. The study is experimental design, controlled type randomized clinical trial, with simple blinding for patients. Eighty adult patients undergoing gynecological surgery in the art, with a surgical time of at least an hour will be randomized and allocated into experimental groups - prewarming system with forced air warming system for 20 minutes, and control - Prewarming with sheet and blanket for 20 minutes. The patients will be kept warm during the anesthetic-surgical procedure. The measurement of temperature will be using a tympanic thermometer. Participants will be followed from receiving the surgical center to the end of surgery. Data will be recorded in validated instrument. Data analysis will be used the Model Linear Mixed Effects and the Structure Error Auto-Regressive.

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.

Low body temperature (hypothermia (HT)) at birth contributes to infant mortality in low-income countries. A study from Guinéa-Bissau indicates that HT results in an increased mortality rate, which persist at least two months after birth. Therefore interventions that reduce the prevalence of HT might have a significant effect on infant mortality. The purpose of the proposed study is to identify risk factors for HT in an in-hospital setting in Guinea-Bissau and to investigate whether continuous temperature-monitoring enabling early detection of HT and treatment can prevent HT <34,5°C.

This investigation is undertaken to investigate if patient warming with BARRIER® EasyWarm active self-warming blanket differs compared to active warming with forced air warming in terms of core body temperature perioperatively. A non-inferiority, prospective, open-labelled, randomized, parallel investigation. Randomized subjects will receive active warming with BARRIER® EasyWarm or with forced air warming. All subjects may receive rescue warming if their core temperature falls below 35.5°C. Rescue warming is optional and defined as the institution's standard of care to prevent hypothermia. The primary purpose is to investigate if there is a clinically relevant difference in core body temperature between the two treatment groups. A total of 60 subjects will be included in the investigation, i.e. 30 subjects in each treatment group. The number includes a 30% drop-out rate.

Low body temperature (hypothermia) is often observed in anesthetized patients. Mild hypothermia increases complications such as surgical blood loss, postanesthesia recovery and the duration of hospitalization. To assess body temperature and minimize hypothermia-related complications, it is important to have accurate and reliable methods of measuring intraoperative core temperature. Common practice is to insert a nasopharyngeal (back of the throat from the nose) probe through one of the nostrils. However, there is no consensus or guideline regarding how deep the nasopharyngeal probe needs to be inserted. This study is being done to determine the insertion depth (or range of depths) that best approximates core temperature, which is temperature of the vital organs, e.g. heart, liver and lungs. Participation in the trial will occur on the day of surgery. The subject will be asked to breathe through one nostril and then the other before receiving anesthesia. The less congested nostril will be selected for study. If there is no difference, then the investigator will use the right nostril. Once under anesthesia, an esophageal temperature probe will be inserted to serve as a reference core temperature, which is used routinely in surgery. Then the nasopharyngeal probe will be inserted into the nostril. Both nasopharyngeal and esophageal temperatures will initially be recorded 45 minutes after anesthetic induction. The nasopharyngeal probe will then be withdrawn 2 cm and after a 3-minute equilibration period, nasopharyngeal and esophageal temperatures will again be recorded. The nasopharyngeal probe withdrawal sequence will be repeated, 2 cm at a time, until only 2 cm remains in the nostril. There will be a total of 10 sets of nasopharyngeal and esophageal temperatures obtained.

This is a randomized, open label, parallel two arm, clinical study, which compare the Bair Hugger forced-air warming blanket and the conventional warming care practice in China on patients undergoing major surgery to determine the impact of maintaining normothermia on intraoperative blood loss, requirement for transfusion of packed red blood cells and the changes of coagulation function.

Shivering is one of the most commonly recognized problem associated with anesthesia, It is believed to be thermoregulatory in origin. Studies suggest that pre-warming the patient prior to the surgery can reduce the chances of hypothermia induced shivering during the post operative period. Forced air warmers are the most frequently used active warming devices in the peri-operative setting. Currently, our hospital does not pre-warm patients but if our study shows that pre-warming reduces post-operative shivering, we will be able to make an evidence based decision to start this practice.

Hypothermia amongst trauma patients is a persistent problem that increases the relative risk of transfusion as well as morbidity and mortality. The investigators propose to conduct a single-centered randomized controlled trial to determine if the use of a zero-heat flux (ZHF) temperature monitor can reduce the incidence of hypothermia amongst trauma patients discharged from the trauma bay (TB). All eligible trauma patients will be randomized to either a standard of care group or an active temperature monitoring group. In the active temperature monitoring group, a ZHF monitor will be placed on respective trauma patients to continuously record their temperatures after they enter the TB at a large tertiary trauma centre, Sunnybrook Health Sciences Centre (SHSC), in Toronto, ON. The investigators will determine if early continuous temperature monitoring can reduce the incidence of hypothermia upon discharge from the TB. Should early monitoring of severely injured trauma patients within the hospital improves discharge temperature, the foundation for two additional research studies will be laid. Firstly, the investigators will enter a vanguard phase of this trial and assess if early warming patients can improve morbidity and mortality in this patient population utilizing a multi-centered randomized controlled trial design. This will be further extended to test whether early monitoring can be applied in a pre-hospital setting (i.e. within ambulances and transport vehicles) to improve admission temperatures in the TB.
