Active clinical trials for "Body Temperature Changes"

Monitoring of intraoperative core temperature is essential for patient safety, reducing the risk of perioperative hypothermia. A recently developed measuring system, SpotOn® (3M, St. Paul, MN), measures the core temperature in a non-invasive manner. Its accuracy in patients undergoing general surgery has not been investigated yet. The study was aimed at comparing the accuracy of the SpotOn® in comparison with the oesophageal probe which is considered the current standard in our care units.

In pediatric patients, the accuracy of body temperature measured with an esophageal temperature probe placed through the gastric lumen of the supraglottic airway device is investigated.

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.

This study is testing a head-cooling device on volunteers to assess temperature reduction.

Hypothermia is a frequent perioperative complication. Its appearance can have deleterious effects such as perioperative bleeding or surgical site infection. Once the temperature has decreased, its treatment is difficult. 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 if different time periods of preoperative forced-air warming reduces the incidence of hypothermia at the end of surgery in patients submitted to laparoscopic urological surgery under general anesthesia. This is an observational prospective study comparing routine practice of pre-warming in consecutive surgical patients scheduled to laparoscopic prostatectomy or nephrectomy between August and December 2018. In this study 64 - 96 patients will be included and prewarming will be applied following routine clinical practice. The prewarming time will depend on the time the patient has to wait before entering in the operating theatre. Measurement of temperature will be performed using an esophagic 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.

In this study, the "Curve of Intraoperative Body Temperature Change in Patients with VATS Surgery" was taken as the main research content to retrospectively analyze the intraoperative body temperature and its change rules of patients who met the research conditions, and draw a trend curve, namely, the curve of body temperature change.Taking "time" as the independent variable and "body temperature" as the dependent variable, the correlation between the two was statistically analyzed.Through the development of the body temperature change curve, we can further understand the phenomenon that the body temperature of patients undergoing VATS surgery changes with the progress of surgery, and longitudinal understand the change trend and the general rule of the body temperature change.The results can provide a basis for clinical development of scientific preoperative evaluation plan, hypothermia prevention strategy and intraoperative intervention plan.

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.

The objectives of this study are to demonstrate that real time physiological status monitoring and the use of optimization techniques during exercise can have a positive impact on physiological status, and to collect metabolic flexibility profiles of young fit adults during rest and exercise.

This study will look at the incidence of post-spinal shivering (PSS) among the obstetrics population and will investigate whether higher operation theater (OT) temperature range or/and IV Ondansetron are able to reduce the incidence of PSS. This is a double-blind, randomized, factorial study, patients will be grouped into 4 groups - LP, HP, LO, HO (L= low-temperature range, H= high-temperature range, P= placebo, O=Ondansetron). All patients undergoing cesarean section under spinal anesthesia will be recruited, and it will be conducted in obstetrics OT.

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.
