Active clinical trials for "Body Temperature Changes"

The investigators will propose a randomized cross-over trial using a uniform and strongly balanced 4-period design in which will include four operations for each surgeon. Surgeons will be randomized to 1 of 4 sequences: ABBA, BAAB, AABB or BBAA. The design is "uniform" in that each treatment appears the same number of times within each sequence (uniform within sequence) and if each treatment appears the same number of times within each period (uniform within each period). It is strongly balanced with respect to first-order carryover effects because each treatment precedes every other treatment, including itself, the same number of times

The aim of this study was to reheat the skin in different ethnic groups after application of cryotherapy.

Cryotherapy after surgery is widely utilised and has numerous practical applications for post-operative rehabilitation. Previous research has suggested that during cold therapy, the skin temperature of the knee should be reduced to 10-15°C to maximise the therapeutic benefits of cooling while avoiding the risk of cold injuries such as nerve damage and frostbite (Wilke and Weiner, 2003; Bleakley, McDonough and MacAuley, 2004). The temperature range at which a device cryocompression device should be set in order to achieve a skin temperature within the therapeutic range of 10-15°C is unknown. Furthermore, there is evidence to suggest that the temperature of the device does not equal that to which the skin is reduced, plus different devices do not achieve the same reduction in skin temperature despite the ice-water within the knee sleeve being maintained at similar temperatures (Selfe et al., 2009). Therefore, it is not sufficient to assume that the temperature setting of a cryo-compression device reflects the skin temperature achieved. The aim of this study is to determine which temperature of ice-water flowing through a Physiolab S1 cryocompression device is able to reduce skin temperature around the knee to within the previously stated therapeutic range.

The Cyprus International Institute for Environmental and Public Health of the Cyprus University of Technology is planning a pilot study of health indicators in relation to spatially varying climatic conditions ranging from the city to the mountainous environment. The purpose of the project is to understand the effect of fluctuations in external climatic conditions on the human body temperature and metabolic biomarkers or stress hormones. Climate change phenomena such as protracted heat waves that create areas with even higher temperatures, especially in urban centers, may have a negative impact on human health. The effects may be acute for an individual with the appearance of discomfort and headaches, while chronic exposures to high air temperatures for the general population have been linked with premature mortality and cardiovascular diseases. Due to climate change that is hitting hard the Mediterranean, these temperature changes have been more and more common in Cyprus in recent years. One of the usual ways of dealing with high temperatures is the use of air conditioners. With sudden and frequent temperature changes during the day, the human body is subject to thermal shock for varying duration and number of times, having wear and tear consequences for the human physiology. The investigators hypothesized that the number, duration and frequency of human exposures to wide gradient (> 8 ° C) of air temperature changes may be related to potential health problems. An intervention potentially reducing the health risk associated with extended exposure to high temperatures in the summer for Cypriots may be the temporary (for a few days or hours) stay in the villages of mountainous area. Most of the mountain communities in Cyprus have consistently lower mean ambient air temperatures of about 10 degrees Celsius than those in the cities, so the investigators anticipate not observing the metabolic hormone alterations induced while being in the city environment.

A prospective double-blinded randomized controlled study to determine efficacy of ephedrine in preserving core temperature in patients under neuraxial spinal anesthesia for knee and ankle arthroscopic surgery.

This study aims to determine effect of body temperature changes during total knee arthroplasty surgery on early postoperative pressure sore formation.

This study examined whether 20 minutes of prewarming prior to gynecological laparoscopic surgery prevented inadvertent post-operative hypothermia. Treatment group received prewarming using a forced air body warming, control group received no active warming system. Both groups were then warmed with forced air warmer intraoperatively.

Perioperative hypothermia is one of the most common anaesthetic complications, increasing the morbidity/mortality of our patients. Active prewarming with hot forced-air devices has demonstrated to be the most effective tool to prevent hypothermia, but its use is only recommended in long-term surgeries and the optimal prewarming duration has not been elucidated. Both spinal anaesthesia associated to the irrigation with liquids at low temperature instilled during transurethral resection (TUR) cause a decrease in the core temperature of the patient. This is a clinical trial comparing different time periods of prewarming in patients submitted to undergo elective transurethral resection. Our aim is to assess the effect of different time-periods of prewarming on preventing perioperative hypothermia during TUR with spinal anaesthesia. Investigators will compare different time periods: 0 minutes (control group), 15 minutes, 30 minutes and 45 minutes. 200 patients are going to be included in this study (50 patients in each group). Measurement of temperature will be performed using a tympanic thermometer and zero-heat-flux temperature sensor. Patients will be followed throughout their hospital admission. Data will be recorded using a validated instrument and will be analysed using the statistics program R Core Team.

Based on client needs and technological requirements, a wearable sensor device was designed and developed using principles of 'social innovation' design. The device underwent multiple iterations in product design and engineering based on user-feedback and then following pre-clinical testing, a techno-feasibility study and clinical trial were undertaken in a tertiary-care, teaching hospital in Bangalore, India. Clinical trial phases I and IIa {studies/pilot studies designed to demonstrate clinical efficacy or biological activity ('proof of concept' studies)} for evaluation of safety and efficacy were undertaken in the following sequence: first with healthy adult volunteers; then healthy mothers; healthy babies; stable babies in the Neonatal intensive care unit (NICU) and then a baby with morbidities. Time-stamped skin temperatures obtained at 5-minute intervals over a 1-hour period from the device secured on upper arms of mothers and abdomen of neonates were compared against readings from thermometers used routinely in clinical practice, radiant warmer and multimodal sensor

Hypothermia is a frequent perioperative complication. When the negative effects of anesthesia on temperature are aggravated by other factors, such as glycine infusion in transurethral resection, temperature can decrease even more. Preoperative warming prevents hypothermia, lowering the temperature gradient between core and peripheral compartments and reducing thermal redistribution. The most recent clinical practice guidelines advocate for active prewarming before induction of general anaesthesia since it is very effective in preventing perioperative hypothermia. However, the ideal warming time prior to the induction of anesthesia has long been investigated. This study aims to evaluate the optimal time period of preoperative forced-air warming to reduce the incidence of hypothermia at the end of surgery in patients submitted to transurethral resection. This is a clinical trial comparing different time periods of prewarming in patients submitted to undergo elective transurethral resection. We will compare different time periods: 0 minutes (control group), 15 minutes, 30 minutes and 45 minutes. 144 patients are going to be included in this study (36 patients in each group). Measurement of temperature will be performed using a tympanic thermometer. Patients will be followed throughout their hospital admission. Data will be recorded using a validated instrument and will be analysed using the statistics program R Core Team.
