Filter by: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.
This study sought to evaluate the vasomotor response in the pain referral area of healthy individuals, performing the same procedure with and without the experience of delayed onset muscle soreness.
During general anesthesia, temperature monitoring is critical especially in pediatrics. Recently developed 3M™ Bair Hugger™ skin temperature which is applied on temporal artery is correlated with core temperature measure by esophageal prove in several studies. Conventional skin temperature over carotid artery is also correlated with core temperature in several studies. The purpose of this study is comparing 2 methods of temperature monitoring in pediatrics. First, conventional core temperature measure by esophageal stethoscope. Second, 3M™ Bair Hugger™ applying on carotid artery.
The patients scheduled to undergo major abdominal surgery in litotomy position will be randomized into two groups in order to compare the effects of two warming techniques during the intraoperative period.
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.
The aim of the study is to study the thermoregulatory responses under real life conditions, such as during wheelchair rugby and basketball matches. A further goal is to develop and validate a standardised field-based protocol, which induces the same thermoregulatory response as during a wheelchair rugby and basketball match. This knowledge allows to investigate strategies to reduce heat stress and to enhance exercise performance (e.g. pre-cooling) in the future, based on standardised conditions.
The aim of the study was to investigate whether a color changing nail polish would be an indicator to assess infraclavicular brachial plexus block success based on skin temperature differences before and after performed the block.
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.
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.
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.
