P4-level protective clothing is not very expensive. At least for the Centers for Disease Control, which is supposed to be wealthy, more than 8,000 sets of P4-level protective clothing are really not affordable.
But protective clothing has a shelf life. From the time it is opened to the time it is stopped, the shelf life of a set of protective clothing is about one year. If Ningyuan Medical College had not had its own p4 laboratory, the Ningyuan City Center for Disease Control and Prevention would never have
I won’t think about buying this level of positive pressure protective clothing, which requires a test to put on and take off. Why buy it? If you have extra funds, wouldn’t it be better to upgrade the central laboratory of the Centers for Disease Control and Prevention?
Therefore, when it learned that there were three cases of pneumonic plague, the CDC's first reaction was to activate three sets of protective clothing in stock and at the same time called the P4 laboratory of Ningyuan Medical College. Did you come up with something?
Biological leak?
Yersinia pestis is a pathogen studied in the p3 laboratory. Research on it does not necessarily require p4 safety standards. However, the p4 laboratory can carry out research on Yersinia pestis. Ningyuan is not a natural plague area.
This was the first time the control center had received a plague case report since its establishment, and they subconsciously suspected the P4 laboratory in their own jurisdiction.
The staff at the Centers for Disease Control and Prevention were heartbroken before they made the call. That was a P4 level laboratory! If the plague could be leaked, who knows what else they might have leaked. What if in a large country like Ningyuan with a population of nearly 10 million?
There's an outbreak of something like Ebola in the city... it's a nightmare.
Fortunately, the nightmare only existed in their imagination. The p4 laboratory of Ningyuan Medical College stated that there was no Yersinia pestis in their laboratory. This ruled out the possibility of leakage from the source. After making the call,
All the staff at the Centers for Disease Control and Prevention breathed a sigh of relief, but that's right. As far as the laboratory settings at the p4 safety level are concerned, even if you want to deliberately leak pathogens from the laboratory, it is impossible. This level of safety laboratory
There are seven optically interlocked airtight doors. As long as one door is open, it is absolutely impossible for the other six airtight doors to be opened. Coupled with the highest level of monitoring and multiple thorough chemical flushing, there is no doubt that
The p4 laboratory leaked Yersinia pestis. It is better to suspect that a Himalayan marmot infected with plague traveled all the way from Xihai Province to Ningyuan. This possibility is slightly higher.
At present, the Municipal Center for Disease Control and Prevention only has three sets of P4 level protective clothing, but there are four sets in the fourth hospital, and the college has also promised full support. In order to prevent the spread of the epidemic and protect the health of medical staff, all P4 protection suits are used.
It has become the safest choice to enter the fourth hospital. After the Class A infectious diseases are reported, there is still a lot of work that needs to be done by the Municipal Center for Disease Control and Prevention. For example, allocate resources, connect with the Provincial Center for Disease Control and Prevention, and comprehensively consider whether it is necessary to report to the national
It is a requirement that the Centers for Disease Control and Prevention and the National Health Commission ask for help to report a Class A infectious disease within two hours after discovering it. Whether the National Health Commission will send an expert team to provide support and guidance depends on the consideration of the epidemic situation and public opinion. At the same time,
Local needs are also an important consideration. Sun Lien and others are still wearing standard protective clothing. Staff from the college office are urgently setting up positive pressure breathing tubes, and mobile high-efficiency air filters transferred from the college are being installed.
In order to ensure the operation of the filter, the hospital office specially deployed two diesel generators to assist. At the same time, a reception and processing center was established to collect and process the excrement of plague patients and medical waste.
The trouble with plague is that there are various routes of infection, and pneumonic plague patients are particularly thorough. In addition to the aerosols produced by their breathing, the patient's feces, urine, vomit, sputum, blood, etc. can spread plague. In order to prevent the spread of
, hospitals need to use a large amount of disinfectants to disinfect and inactivate patients' medical waste and domestic waste. For solid feces, even 20% bleach powder emulsion needs to be added, mixed and disinfected for two hours.
If there is a British person here, this is a job that is very suitable for him/her.
Before entering the clean room, all Sun Lien could do was think about things in his mind to distract himself.
He is also afraid.
The plague is the Black Death. Sun Lien has already had some preliminary ideas about how terrible this disease is that has ravaged the world for thousands of years and caused the death of all residents in countless cities.
The incubation time from infection to onset of pneumonic plague is incredibly short. The fastest recorded onset of pneumonic plague is 30 minutes. From contact with the patient to onset of illness, it only takes 30 minutes. After the onset of the disease, the patient's
The condition will begin to deteriorate rapidly, and death will occur within about three days. In some ways, pneumonic plague can even compete with Ebola virus. This is just because the causative agent of plague is bacteria, and many antibiotics are effective against plague.
The effect is not as scary as viral infectious diseases.
"Okay, everyone gather together." Sun Lien was thinking wildly. Huang Wenhui, the director of the Department of Respiratory Medicine, had already issued instructions to the surrounding medical staff, "Take preventive oral ciprofloxacin capsules every twelve hours.
"
In addition to using corresponding protective equipment, medical staff also need oral antibiotics for preventive treatment. Among the four preventive drugs recommended in domestic diagnosis and treatment guidelines, tetracycline and compound sulfamethoxazole tablets are used in relatively large amounts, while doxycycline
Su Ze has obvious hepatotoxicity, so Director Huang Wenhui chose to have everyone take ciprofloxacin for preventive treatment. The pharmacy in the hospital can easily provide drugs anyway. Since they are considered "labor protection supplies", it is natural to choose the right medicine.
The one that causes less harm to medical staff.
"I'll go in with you." Watching Sun Lien and others take the capsules, Director Huang himself swallowed two capsules and put on the mask again, "The laying of the clean room is still being done, time waits for no one,
I will discuss with the hospital staff and at least let me go in to check on the patient's condition and let the imaging department bring over a bed X-ray. They definitely cannot go to the CT room in this situation, and having a chest X-ray is better than not having one at all."
Sun Lien nodded, and then said, "I'll go in with you."
This time, Sun Lien really wasn't overly arrogant, but made a decision after comprehensive consideration. Among the entire treatment team, he is the most suitable person to enter the clean room. First of all, under the first-diagnosis responsibility system, there must be someone in the treatment team.
The doctor took over the three patients; secondly, Sun Lien had been in the room with patients who needed to be isolated, and had completed many rescue operations. Compared with several other doctors in the group, Sun Lien had obvious ability to deal with emergencies.
It is better and more comprehensive; thirdly, with the help of the director of respiratory medicine, Sun Lien's status as a trained person is actually more suitable to help others; and lastly, he has a status bar that he can use.
With the status bar, he can monitor changes in the patient's condition as quickly as possible, and can actually apply these changes in actual treatment. For patients with pneumonic plague, even if there is just a little more help, the results may be
They are two completely different extremes from death to life.
The most important thing is that Sun Lien has learned well. He has experienced the horrors of medical occupational exposure and nosocomial infection more deeply than other emergency doctors present. He himself was quarantined for seven days, and his director was sent to the hospital.
In Africa, his cousin is still hospitalized in the picu, and it seems he can barely save his life.
Because you are afraid, you must be brave. Sun Lien clenched his fists and said firmly to Director Huang Wenhui, "I will go in with you."
"Aren't you afraid?" Director Huang looked at Sun Lien's face and suddenly asked with a smile, "It's plague inside. Are you not married yet?"
"My girlfriend is studying in the UK." Sun Lien almost gave himself a flag, but fortunately, he held back. "As for the plague... I'm not afraid of embarrassment, of course I am. But what's the use of being afraid? I'm afraid of the patient.
Get better?" He looked at Huang Wenhui and said seriously, "I am an emergency physician, and my job is to use all means to stabilize the patient's condition, and then transfer them to your specialty for further treatment. This is my profession.
"
After a while, Director Huang laughed, her smile was a little bold. She raised her hand, reached Sun Lien's shoulder with some difficulty, then patted her hard, and praised in Cantonese, "Hello, handsome! I'll take a look.
