Precautionary measures for hypothermia during encircling

Pre-operative assessment and pre-heating, ambient temperature, surface temperature, liquid temperature, etc. are the protective measures for the pre-occupancy convalescence of the lower body. Pre-operative assessment and pre-heating: Prior to the operation, the potential for, and extent of, a decrease in, body temperature during the operation, based on the patient’s condition, age, type of operation, area of exposure to the internal abdominal cavity, during the operation, and the integrity of the skin (e.g., burns, skin inflammation, rashes, pressure acne) and the development of measures to protect the temperature and record the base temperature; 2. ambient temperature: maintenance or increase of the surrounding environment temperature reduces irradiation. If room temperature is below 21°C, anaesthesia patients are likely to experience low temperature; 3. Since most of the heat generated by metabolism is lost through skin, effective body temperature-preservation methods can reduce loss of skin heat; 4 and liquid warming: warming of imported liquids and blood, especially patients who require a high volume of fluids. In the case of a large quantity of liquid rinsing cavity (the thorax, abdominal cavity, bladder, etc.), warmer liquid should be used to avoid loss of heat. The low temperature control measures combined with the patient’s heat comfort, and the patient’s body temperature maintenance target is 36°C. Pre-operative anesthesiologists should carry out a classification assessment of the patient’s hypothermia risk, and implement individualized encircling measures. On the basis of a Predicators scale, which is based on risk factors such as patient BMI, pre-operative base temperature, scale of operation, and time of anaesthesia, a low-temperature risk projection APP (0 ~ 70% low risk based on percentage of risk projection; 70 ~ 90% medium risk; 90% high risk; 90% high risk) has been developed. Pre-temperature protection means that pre-operative patients accept active temperature protection measures to increase storage and low temperature thresholds, reduce core temperature, reduce heat distribution. Whether it’s an intravertebrae, a drunk or anesthesia, pre-temperatures help keep the patient’s body temperature normal. Compared to conductor heating systems such as conductor heat blankets, water heating systems, FAW equipment and conductor heating systems such as conductor heat blankets, cycling water heating systems, FAW equipment is part of current heating, one of the main heating methods currently widely used in clinically, heating the air-to-flow or exposure-to-conductor machines, and more effective protection against cooling during encirclement (tampons, cotton blankets) and recommence of low temperature patients. The liquids above 1,000 ml and the refrigerated blood products are recommended for re-transmitting with ventilating equipment from veins to above 37°C, but the blood products should not be warmer than 43°C and should not use bathing and microwave heating methods. In addition, the use of heat lenses or the heating of CO2 abdominal gases can reduce the loss of heat in the process.
