Original title: Nucleic acid testing doctors and nurses suffering from heat stroke, body temperature up to 64 ℃, can protective suit wear? Core Summary: 1. Because of the continuous high temperature and the airtight protective suit. According to media reports alone, nearly 100 medical workers have been involved in nucleic acid tests for fainting and heat stroke. Heat stroke is severe heatstroke, which is caused by the failure of the human body to regulate its body temperature normally in a high temperature and humidity environment, resulting in a rapid rise in core temperature of more than 40 degrees Celsius, convulsions, coma and other emergencies, and even death. The case fatality rate of heat stroke exceeds that of COVID-19, and the brain damage caused by heat stroke is irreversible. 2. The medical protective suit used by nucleic acid testing volunteers can protect the human body in all aspects. ? Block the penetration of body fluids, viruses, etc. A study by the National University of Singapore shows that the body temperature will reach 64 degrees Celsius after wearing protective suit for an hour at about 35 degrees Celsius. Wearing this protective suit for a long time and exposed to the sun, medical staff are prone to dyspnea, excessive dehydration, facial swelling and other symptoms, greatly increasing the risk of heatstroke. 3. According to scientific research COVID-19 can only survive for a few minutes outside in sunlight, and according to research released by the National Health Commission, it can survive for only a day on most surfaces at room temperature. After the protective suit is soaked by sweat, its protective performance has actually been greatly reduced. Therefore, there is no need to use medical protective suit when doing nucleic acid testing outdoors, and our epidemic prevention policy should be more up-to-date. 30 days of high temperature seamless connection 40 days of "super long version" dog days, anti-epidemic was "baked" test, nearly 100 nucleic acid testing medical staff, due to protective suit of heatstroke or diagnosed with heat stroke Expand the full text In the ultra-high temperature weather of 38 to 44 degrees, what kind of experience is it for medical staff to wear protective suit for nucleic acid testing? Xie Chunhua, a nurse at the People's Hospital in Nanchang County, Jiangxi Province, released a video on July 14, reporting that she suffered from severe heatstroke, also known as heat stroke, after wearing a protective suit to conduct nucleic acid testing for several days in 38 degrees Celsius outdoor weather. In the video, she was lying on a hospital bed in the emergency room, and her limbs kept twitching. "It's a seizure, which means her brain has been damaged by heat," a surgeon in Zhejiang Province who went by the name Baiyi Bobcat said on social media. Heat stroke patients, even if they can be rescued, their brain damage is irreversible. On the same day, in Shijiao Town, Fogang County, Qingyuan City, Guangdong Province, a nucleic acid testing site worker suddenly fainted and suffered from heatstroke due to high temperature. On July 4, Liu Li, an employee of the county hospital, fainted from heatstroke during nucleic acid sampling, according to the WeChat official account of the Health Bureau of Qishan County, Shaanxi Province. On July 9, a medical worker in Zhumadian, Henan Province, suffered from heatstroke at the nucleic acid testing point. According to incomplete statistics, only the media reported that the medical staff of nucleic acid testing in various places fainted, and as many as 100 medical staff suffered from heat stroke. This result is caused by wearing airtight protective suit at ultra-high temperatures above 38 degrees. According to the official account of the People's Hospital of Xixiang County,Quickly Delivery Disposable Protective Clothing, Shaanxi Province, the medical staff started their "sweat steaming" nucleic acid sampling mode under the heat wave of 38 degrees Celsius. The thick protective suit is airtight, and the body temperature under the protective suit reaches 64 degrees Celsius! Over the past month, ultra-high temperatures have swept across the country. According to the National Climate Center, the highest temperatures at 71 national meteorological stations have broken the historical record. Among them, the daily highest temperatures in Lingshou (44.2 ℃), Gaocheng (44.1 ℃), Zhengding (44.0 ℃) and Yanjin (44.0 ℃) in Yunnan have exceeded 44 ℃. However, the real dog days of summer began on July 16. Dog days are the muggy weather with the highest temperature and humidity in a year, and all parts of the country will enter a continuous high temperature mode. Generally, the dog days are 30 days, but this year there are 40 days, which belongs to the "super-long version". This summer's hot weather is not characteristic of China, and there are also heat waves in the Americas and Europe.
However, in the face of the hot weather, China is facing the most severe impact: because of the meticulous anti-epidemic, disease control and epidemic prevention personnel and community epidemic prevention volunteers in more than ten provinces and cities in China need to wear protective suit for a long time; at the same time, because the infectious power of Omicron BA.2 and BA.5 has increased greatly,Medical Quickly Delivery Antivirus Coverall, all regions have to increase the frequency of nucleic acid testing. Encounter the scorching sun, queuing for nucleic acid is easy to get sunstroke, which is the "baking" test against the epidemic; however, the Baymax wearing protective suit, because they stick to the sun for a longer time, "baking" test is more difficult. Severe heatstroke ( "severe heatstroke") is called "heat stroke" in medicine. Due to exposure to high temperature and humidity, the human body is unable to regulate its normal temperature, resulting in a rapid rise in core temperature. When the temperature exceeds 40 degrees Celsius, acute symptoms such as convulsions, coma and multiple organ kinetic energy disorders will occur. In the most serious cases, it will lead to death. According to the epidemiological investigation of reported cases of heatstroke in Ningbo from 2011 to 2014 [1], a total of 4415 cases of heatstroke were reported in Ningbo during these four years, of which 341 cases were "heat stroke", accounting for 7. 72%; 13 cases died of heatstroke, the overall case fatality rate of heat stroke was 0. 29%, and the case fatality rate of "heat stroke" was 3. 81%. According to the data reported by the Health and Health Commission, as of July 13, 2022, a total of 227,030 confirmed cases of COVID-19 and 5,226 deaths were reported in the mainland, and the case fatality rate of confirmed cases of COVID-19 was 2.3%, which was lower than the case fatality rate of "heat stroke". Since March, a total of 650,000 people have been infected with COVID-19 in Shanghai, the vast majority of whom are asymptomatic, with an case fatality rate of less than 0.1%. At present, the decline of the case fatality rate of COVID-19 is due to the decline of virus virulence and the protective factors of immune barrier against severe illness and death after large-scale vaccination. According to case fatality rate data, Omicron infection is not fatal to heatstroke! Viruses can be transmitted, heatstroke will not, but "there is nothing new under the sun", as long as it is hot weather, as long as not hiding in air-conditioned rooms, everyone faces the risk of heatstroke. People who are exposed to the sun are at greater risk! On July 14, a nucleic acid testing medical staff was soaked through at the nucleic acid testing site in Baoshan, Medical Disposable Coverall ,Full Body Disposable Coverall, Shanghai. The temperature on that day was 40.6 degrees. Shanghai has been 40 degrees Celsius for several consecutive days, ranking first in the country. Singapore's research shows that under the temperature of about 35 degrees Celsius, the body temperature of the human body will reach 64 degrees Celsius after wearing protective suit for an hour. Medical protective suit, isolation gowns and surgical gowns can be broadly referred to as protective suit, but in order to protect against COVID-19, medical and epidemic prevention personnel wear medical protective suit. The medical protective suit can cover the head, the trunk and the ankles of a human body, and can protect the whole body of the human body in 360 degrees by combining with personal protective articles such as masks, medical shoe covers, masks and the like. In terms of material, medical protective suit has anti-synthetic blood penetration performance, which can prevent the penetration of blood and body fluids carrying viruses; in terms of filterability, medical protective suit can also prevent the penetration of droplets and aerosols carrying viruses. These functions of medical protective suit are not available in isolation gowns and surgical gowns, so they become the standard of strict defense. However, protective suit can prevent viruses, but not heatstroke! On the contrary, protective suit can greatly increase the risk of heatstroke. A study by the National University of Singapore shows that at a temperature of about 35 degrees Celsius, after wearing protective suit an hour, the body temperature will reach 64 degrees Celsius [2]. Under direct exposure to the sun, the temperature may be even higher. What is the concept of high temperature? Not long ago, after the high temperature weather in Henan, the highest ground temperature reached 74 degrees Celsius. Some netizens did an experiment, after throwing ants on the hot ground, the ants could not live for more than three seconds. To this, the netizen comments say: The ant of Henan "can be difficult"! "Difficult" is not only the ants in Henan, but also the Baymax who does nucleic acid testing under high temperature! In order to strictly block the path of possible invasion of the virus, the sleeves and trouser legs of the protective suit should be tightened.
A video on the Internet showed that when Bai Bai loosened his trouser leg, the sweat inside flowed out. Summer is prone to heatstroke, heat stroke, epidemic prevention, medical staff wearing protective suit, long time in high temperature, even if made of special materials, the body will be prone to discomfort. As early as June 2021, a questionnaire survey of 3658 medical staff in Guangzhou Medical University showed that after wearing protective suit, 80% of medical staff sweated heavily, 55.2% of medical staff had dyspnea, and 46.8% of medical staff reported excessive dehydration. Adverse events such as facial swelling (74%), hand maceration (56.7%), and visual impairment (49.3%) were also reported. [3] In the hot summer, even if it is not directly exposed to the sun, the health risks of protective suit can not be ignored. On July 4, a female nurse of the medical team in Wuxi, Suzhou, suddenly fainted from heatstroke while climbing the stairs to do nucleic acid for residents. According to reports, she climbed the stairs to take nucleic acid samples for more than 1100 residents that day. Thanks to timely treatment and cooling, the nurse avoided shock. COVID-19 can only survive for less than 10 minutes outdoors in the summer sun? The sun can kill viruses. Is it necessary to wear protective suit for outdoor nucleic acid testing? The original use scenario of medical protective suit is to avoid contacting the virus and carrying the virus to the hospital and community to cause the spread of the virus when the medical staff treat the infected person. During the epidemic in Wuhan at the beginning of 2020, many doctors and nurses were infected because of the sudden outbreak of the epidemic and inadequate protection. After the protective suit was well supplied, there were few reports of medical staff being infected. After the outbreak in the United States in 2020, many health care workers had to use garbage bags to make their own protective suit because there was not enough protective suit. With the development of Made-in-China, the use of protective suit has extended beyond hospitals. In international travel, protective suit has become a feature of flight attendants and passengers from China. Excessive protection is not entirely beneficial. In March 2020, a passenger returning from Australia wore a mask and gloves throughout the flight, and wore a white plastic raincoat of good quality as a protective suit. On the plane, passengers are already feeling tired and hot. After the plane arrived in Shanghai, the passenger fainted as soon as he left the cabin door, and finally died of ineffective medical treatment. From the perspective of "scientific anti-epidemic", it may be necessary to re-examine or change some places in time, such as whether it is necessary to wear protective suit in the outdoor high temperature environment. As early as April 2020, research by the Science and Technology Agency of the US Department of Homeland Security has found that the half-life of COVID-19 is only a few minutes in outdoor sunlight. Viruses lose their activity and infectivity quickly in outdoor sunlight, resulting in relatively few infections. In March 2020, when Los Angeles held a 10,000 marathon as scheduled, there was no large-scale epidemic. This is the deputy director of surgery of a hospital in Zhejiang Province, who photographed traffic policemen and epidemic prevention and control personnel wearing blue clothes in the hot sun. He wrote on social media that it was the clothes he wore when he operated on infectious patients. This kind of surgical gown has a fatal defect, that is, it will feel very stuffy and airtight after wearing. Zhejiang has been in the high temperature of about 40 degrees recently, in the highway scene, only need to wear a mask to protect the virus invasion, wearing such clothes is easy to heatstroke, not necessary. It is precisely because COVID-19 is mainly transmitted indoors that countries are emphasizing the importance of wearing masks indoors and in confined spaces. At present, in order to reduce the risk of infection, nucleic acid testing sites are also selected in outdoor ventilated places. But in such a scenario, it is worth further exploring whether there is a need to wear protective suit. First of all, compared with other countries, the domestic epidemic is not serious. As a country with a population of 1.4 billion, there are only a few hundred new infections per day at most. In the queue for nucleic acid screening, the chance of a person carrying the virus is very low.
If there are a large number of infected people who really need to wear protective suit, then it should not only be worn by epidemic prevention personnel, but also by all those who participate in nucleic acid testing. Secondly, even if there are virus carriers in the screening population, the virus discharged into the air will be attached to the protective suit, so it will be disinfected under the sunshine of more than 40 degrees. There is no need to use fully enclosed protective suit, which is easy to cause heatstroke. At most, only simple and breathable isolation clothes are needed, and the protective effect can be achieved with masks and conventional hygienic operations. It should be pointed out that even if the virus dies in the sun, if nucleic acid testing is done, it can still be positive. Therefore, positive detection in the environment is not a reason to wear protective suit. Not only that, because of the high temperature, the protective suit is often soaked by sweat, and the protective performance has actually been greatly reduced. On July 12, the National Health Commission issued the Notice on Further Optimizing the Prevention and Control of COVID-19 pandemic in Imported Goods, requiring all localities to stop testing imported non-cold-chain goods for COVID-19 nucleic acid. For low-risk imported non-cold chain items, even preventive disinfection is not required. "The latest research results show that the new coronavirus has a short survival time on the surface of most articles at room temperature, and all of them are inactivated within one day," the notice said. The notice did not explain when the latest research results were obtained, but now the official document has been passed, indicating that the thinking of guiding the fight against the epidemic has changed. The new regulations of the Health and Health Commission are actually the implementation of scientific anti-epidemic, which will not lead to a large-scale outbreak of the epidemic, but also reduce unnecessary anti-epidemic costs. According to the latest news on July 16, in order to prevent medical staff from heatstroke, Nanchang City has adopted heatstroke prevention and cooling measures: outdoor sampling personnel no longer wear protective suit for sampling, but wear disposable isolation clothing; sampling sites are arranged in the shade as far as possible to avoid direct sunlight; Sampling personnel change their posts for one hour, and place refrigerators, fans and ice cubes around the medical staff to help cool down. Sampling points are equipped with heat-proof medicines and living materials such as Huoxiang Zhengqi water to ensure the safety and health of nucleic acid sampling medical staff. With the establishment of community immunity and the decline of virus virulence, we need more anti-epidemic measures to keep pace with the times! It is expected that one day, the Health Commission will give specific scientific guidance for the use of protective suit under high temperature conditions.
