NCT06517147
The aim of this project is to test the rate of cooling following exercise in the heat utilising the CRYOGENX Cryosuit device i) against passive cooling, and ii) to quantify the rate of cooling and compare this rate with established cooling intervention thresholds i.e. -0.11 to 0.15°C.min-1. As this project is to determine the efficacy of the intervention in populations equivalent to sporting and military personnel, these aims will be tested in young (18-40 year old) healthy male and female participants whom participate in regular physical activity. As a commercially funded project, the experimental design implemented will closely replicate that of the independent investigation into the efficacy of the CAERvest® device.
NCT06389604
As the ongoing progression of climate change exposes individuals to elevated temperatures and an escalating frequency of extreme heat events, the risk of more intense and prolonged heat waves raises significant concerns for public health, particularly among vulnerable populations. The physiological response to acute heat stress involves involuntary thermolytic reactions that may strain the cardiovascular system, especially in individuals with pre-existing vulnerabilities. Heat acclimation has been identified as a potential strategy to enhance thermoregulation and mitigate the adverse effects of heat stress. While existing research primarily focuses on athletes and military, this study aims to investigate the impact of a practical heat acclimation strategy, combining passive and active heat exposure, on thermophysiological, cardiovascular and metabolic parameters in healthy overweight adults. The study targets a population at increased risk for heat-related complications, seeking to provide realistic guidelines for broader application when a heat wave appears on the weather forecast.
NCT06230172
The purpose of this study is to determine the safety and feasibility of weaning from the incubator at a lower post-natal weight at 1600 grams. Our hypothesis is that early weaning from the incubator to a crib/bassinet is safe and may result in a decrease in length of hospital stay while maintaining appropriate growth velocity. Specific outcomes the investigators will evaluate are the length of hospital stay and growth velocity at early weaning.
NCT06175975
The focus of the clinical research is to examine whether there is a difference in body temperature measurements with or without positioning the auricle in the measurements made with a tympanic membrane thermometer in pediatric patients aged 3-17, and to examine the effect of positioning the ear on comfort behaviors.

NCT04311268
Body temperature is one of the markers of biological rhythms. The precise determination of the functioning of the biological clock for an individual is essential to understanding his physiological state at a given time. This condition is dependent on the "timing" of its central clock on the time scale (chronotype). The provision of a simple-to-use (F2D cuff), non-invasive and time-dependable temperature tool and the creation of appropriate algorithms would allow access to the operation of the central clock and open up many therapeutic applications.
NCT05179681
Background: Hypothermia would increase the risk of bleeding, infection, cardiac complications and delay recovery. The transnasal humidified rapid-insufflation ventilatory exchange (THRIVE) could not only provide the larger oxygen preserve but also humidified high flow. However, Objectives: We wanted to investigated whether the humidified high flow of THRIVE would affect perioperative body temperature (BT). Patients and methods: We reviewed the medical records of adult patients undergoing non-intubated video-assisted thoracic surgery (NIVATS) have been retrospective reviewed. All patients have received force air warming. Multiple linear regression analysis was used to determine which factors were associated with BT loss. Expected result: In patients receiving NIVATS under force air warming, the use of THRIVE may provide more efficiently BT preserve, although the patients with oxygen mask could have acceptable BT preservation. The more BT loss is associated with the advanced age and higher BMI level. The anesthetic duration is not associated with the BT loss.
NCT05140707
This study aimed to determine the effect of virtual reality on pain, anxiety, and vital signs of oncology patients undergoing port catheter implantation. The study was carried out with 139 participants (69 intervention, 70 control) between September 2019 and January 2020. A patient identification form, state anxiety inventory, a table for vital signs, and a visual analog scale for pain severity were used for the data collection. Data were collected from the patients before, during, and after the implantation. In the intervention group, a virtual reality device, movies, and relaxing music were provided to the patients.
NCT04463537
Objective: The aim of this study was to investigate the effect of auricle position on body temperature measurements made with tympanic membrane thermometer in adult patients. Methods: The study was conducted with a quasi-experimental design with a pre-test and a post-test. A total of 143 patients who fit the inclusion criteria of the study were included in the sample. The research carried out between 1 November - 31 December 2016 in the emergency department. Body temperature measurements were carried out on the patients in the study firstly by not changing the position of the auricle and then repeated after a minute, this time by changing the position of the auricle. Results: The difference between the measurement values found in two different positions was 0.31 0C, and the Bland Altman plot showed that the differences were distributed systematically around the value 0.31. The difference between the lengths of measurements performed on two separate positions was detected to be 1.08 second. During body temperature measurements performed through giving position to auricle, 59.2 % of the patients never felt discomfort. Conclusions: It was found in the comparison of two positions that there was a significant difference between the tympanic membrane thermometer measurements made by positioning the auricle and those without positioning.
NCT04351425
Background: To maintain the body temperature of preterm newborns is one of the essential criteria for discharge from hospital. Aim: we aimed to assess the feasibility and the safety of an early weaning protocol from incubator to unheated cot at 1400 g preterm newborns. Methods: This was a randomized control trial with preterm neonates with birth weights \< 1400 g conducted at King Fahad Medical City, Riyadh, Saudi Arabia. We compared newborns weaned to cot at a weight of 1400 g to newborns weaned at a weight of 1600 g. The outcome was to assess the feasibility of the protocol in terms of temperature control and average weight gain. Results: A total of 23 preterm neonates were recruited in this study. The baseline characteristics were similar except for the gestational age was higher in the newborns enrolled to 1400 g group. Early weaning was achieved in 100% of newborns without significant adverse effects on temperature stability or weight gain. Incidence of low and high temperatures per newborn and the average weight gain before and after transfer and after transfer were not different between the two groups. Conclusion: Our results showed the feasibility and safety of 1400 g weaning protocol for preterm newborns, without any adverse effects or increasing the neonatal length of hospital stay. Further investigations in larger patient groups are recommended.

NCT03068143
This prospective observational study is designed to investigate the relationship between brain temperature, axillary temperature, rectal temperature, and bladder temperature of postoperative patients with brain trauma, and the relationship between brain temperature and prognosis. This study is conducted based on the following important assumptions. First, brain temperature of postoperative patients with brain trauma should be higher than the axillary temperature, rectal temperature and bladder temperature. Second, the consistency of brain temperature and bladder temperature is better than the consistency of brain temperature and axillary temperature, as well as that of brain temperature and rectal temperature. Third, brain temperature can help clinicians to predict the prognosis of patients with brain trauma. Therefore, brain temperature monitoring is significant in postoperative intensive care and treatment of patients with brain trauma.

NCT01011855
The purpose of this study is to compare three radiant warmer beds that contain different computer heating software and different bed styles. Radiant warmers are used in many neonatal intensive care units (NICU) to provide heat to infants to help regulate an infant's temperature. It is common for babies to require care on an open bed that provides heat to the baby according to the baby's needs and at the same time allows easy access to the baby for care and necessary procedures. There are different styles of beds, each with unique computer software that can guide how a bed's heater output is automatically adjusted according to a baby's temperature needs. It is unknown which style of bed or method of heating might be best. This study seeks to evaluate infant responses to three different types of radiant warmer beds.
