Filter by:Because autonomic neuropathy affects the constriction of thermoregulatory blood vessels, it is more difficult for diabetic patients to maintain their own body temperature in cold environments than normal people, and therefore it is more difficult for diabetic patients to maintain a relatively constant body temperature regardless of the temperature of the environment than normal people. So are diabetic patients under general anesthesia more susceptible to intraoperative hypothermia? How does heart rate variability change in diabetic patients under general anesthesia? If diabetic patients are more susceptible to intraoperative hypothermia under general anesthesia, is this related to their cardiac autonomic dysfunction?
This study is a randomized clinical trials that aim to determine the effect of Indocyanine Green (ICG) titration dose on the intensity degree of ICG fluorescence imaging results. In addition, this study will also determine the relationship of other indicators such as flap surface temperature, transcutaneous pressure of carbon dioxide (TcPCO2), transcutaneous pressure of oxygen (TcPCO2), HIF - 1 alpha expression, and flap histopathology morphology to the intensity degree of ICG fluorescence imaging results with titrated doses.
In Traditional Medicine, auricular acupressure (AA) is one of the non-pharmacological treatment methods commonly utilized due to its safety and convenience. AA involves the application of a taped seed of Vaccaria (with a diameter of 2mm) on specific ear acupoints to manage various disorders. Among these, chronic lower back pain is prevalent. According to Traditional Medicine, the Kidney point is selected for this condition due to the belief that "The lumbar region is the house of the Kidneys". However, evidence supporting this correlation is still lacking. In this study, the aim is to assess the relationship between the Kidney point and the lumbar region by monitoring changes in skin temperature through the application of AA on this acupoint.
Background: There are many post-procedural treatments touted to improve comfort and decrease downtime, but very few prospective randomized studies. Aims: To analyze the safety and efficacy of a post-procedural biotech cellulose mask Patients/Method: Fifteen patients undergoing either a microneedling with radiofrequency (n=5), non-ablative fractional (n=5), or full erbium;YAG resurfacing (n=5) treatment were randomized to receive a Velez biotech cellulose mask on one side of the face for 30 minutes after the procedure and for two hours a day until healed. Canfield Visia photos and thermal photographs were taken 30 minutes after the procedure and daily until healed. The investigator and blind evaluators reviewed the photos and subjects answered daily questionnaires.
The goal of this study is to learn about the effect of heat and humidity on cognition and health. The main question[s] it aims to answer are: type of study: interventional participant population: 20-40years, both gender, healthy Participants will be exposed for 4 different sessions of 8 hours at a time, to 32˚ C or 25˚ C in combination with relative humidity of 30 %RH or 70 %RH.
The global populace is at growing risk of heat-related illness due to climate change and accompanying increases in the intensity and regularity of extremely hot temperatures. In heat-exposed persons, heat gain from the environment and metabolism initially exceeds the rate of heat dissipation from the skin. Heat is stored in the body, causing core and skin temperatures to rise, which in turn triggers autonomically mediated elevations in cutaneous blood flow and sweating to facilitate heat loss. If conditions are compensable, heat loss increases until it balances total heat gain. At this point, the rate of heat storage falls to zero (i.e., heat balance is achieved) and body temperature stabilizes, albeit at a level elevated from thermoneutral conditions. If, however, the maximal achievable rate of heat dissipation is insufficient to offset heat gain, conditions are uncompensable, and prolonged exposure will cause a continual rise in core temperature that can compromise health if left unchecked. The environmental limits of compensability (i.e., the temperatures/humidities above which heat balance can not be maintained) are therefore an important determinant of survival during prolonged heat exposure. Evaluating this limit and how it can be modified (e.g., by behavior or individual factors like age or sex) is an increasingly important and active field of study. Contemporary evaluations of the environmental limits of compensability utilize "ramping protocols" in which participants are exposed to increasing levels of temperature or humidity (in 5-10 min stages) while core temperature is monitored. It is generally observed that core temperature is relatively stable (or rises slightly) in the early stages of exposure but undergoes an abrupt and rapid increase as heat stress becomes more severe. The conditions (e.g., wet-bulb temperature or wet-bulb globe temperature) at this "inflection point" are taken as the limits of compensability. That is, it is assumed that inflection corresponds to the demarcation point, below which core temperature would remain stable for prolonged periods (theoretically indefinitely if hydration is maintained) but above which heat loss is insufficient to offset heat gain, causing core temperature to rise continuously. Despite the increasing use of these protocols, no study has clearly demonstrated their validity for identifying the environmental limits of compensability. The goal of this project is therefore to assess the validity of ramping protocols for determining the ambient conditions above which thermal compensation is not possible. Enrolled participants will complete four experimental trials in a climate-controlled chamber: one ramping protocol followed by three randomized fixed-condition exposures. In the ramping protocol, participants will rest in 42°C with 28% relative humidity (RH) for 70 min, after which RH will be increased 3% every 10 min until 70% RH is achieved. The core (esophageal) temperature inflection point will be determined. For the fixed-condition exposures, participants will rest in i) 42°C with RH ~5% below their individual inflection point (below-inflection condition), ii) 42°C with RH ~5% above their individual inflection point (above-inflection condition), and iii) 26°C with 45% RH (control condition). Comparing the rate of change in esophageal temperature between each fixed-condition exposure will provide important insight into the validity of ramping protocols for identifying the limits of compensability.
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. The temperature to which a 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 setting of the device does not equal that to which the skin is reduced. Therefore, it is not sufficient to assume that the temperature setting of a cryocompression device accurately reflects the achieved skin temperature. Modern cryotherapy devices mostly consist of some sort of cuff that can be wrapped around the knee, with a connecting tube to a central unit that supplies and circulates cold water to and from the cuff in order to cool the intended body part. The Hilotherm is one such device for use in this way, but its ability to reduce skin temperature to within the target therapeutic range is unknown. The aim of this study is to determine whether the Hilotherm device is capable of reducing skin temperature of the knee to within the 10-15℃ therapeutic range during a standard 30-minute treatment.
Perioperatively, patients experience an unnecessarily high level of side effects associated with their treatment. These side effects include nausea, severe pain, anxiety, and stress. Moreover, many patients develop postoperative delirium (POD) and neurocognitive dysfunctions, often resulting in long-term cognitive impairment, decreased quality of life, and increased mortality. However, physicians, nurses and their institutions do not receive structured feedback regarding these aspects of each patient's well-being. They may therefore be unable to engage in the essential cause-and-effect learning necessary to evaluate and consecutively reduce such side effects. Effective guidelines conform prevention is the proven key to shielding our patients from adverse Outcomes.
