How should the hospital deal with the massive power outage caused by the rainstorm in Zhengzhou?

The heavy rain in Zhengzhou has brought people from all walks of life back to reality.

Zhengzhou, a big city with a population of10 million, was filled with sadness in a rainstorm. A large number of people are trapped in streets, subways and hospitals.

One Weibo caught my attention, that is, the author's father was hospitalized in ICU, and he was wearing a ventilator. After the power failure, not only can not be contacted, but also the ventilator can not operate, and life and death are uncertain.

Many people also ask me, what will happen to the hospital if there is no electricity supply at all? Will many people die?

Where's the ventilator

In fact, the principle of ventilator is to blow air into the patient's lungs at a certain frequency. In the absence of a ventilator, you can use a breathing balloon to squeeze the ball by hand, or you can squeeze air into the patient's lungs. But the problem is that the first hand is very tired, and it will be ok in a few minutes. If it takes dozens of minutes, it is difficult to persist.

Second, the hand kneading efficiency is low. If the patient is seriously ill, oxygen saturation will not be maintained quickly.

However, as long as there are enough people, everyone can take turns to operate and squeeze hard!

The second is the drug intravenous infusion pump. You must have heard that some patients rely on drugs to extend their lives. This medicine is usually used to maintain blood pressure and breathing.

This gadget can control the dose and push the drug into the patient's body. If the blood pressure is too high and too fast, the peripheral blood vessels will be necrotic. If the blood pressure is too slow, the blood pressure will not be maintained, and the heart, lungs and brain will die.

If not, people can only push the medicine manually or change it into an infusion bottle. You can count a few drops a minute according to the time, and experienced nurses can also control the speed.

The third is the display.

Mainly the patient's heart rate, breathing, blood pressure and blood oxygen.

The first line is the heart rate; The second line is blood oxygen and respiratory rate (reflecting whether the body is short of oxygen); The third is blood pressure. The most important thing is the first three lines.

What if not?

1, the heart rate can be counted as pulse, or the pulse of aorta. If it is arrhythmia, such as premature beats, atrial fibrillation, etc. You can listen with a stethoscope.

2, breathing frequency can be seen from the chest ups and downs, but the oxygen saturation is not very good to detect, if you see the body cold, blue lips, this time has been hypoxia for a long time.

3, blood pressure, you can use a manual mercury sphygmomanometer to measure, just keep measuring. But more accurate arterial blood pressure is difficult to measure.

In short, if there is none, at least one person needs to stare at the observation and measurement.

The uniqueness of ICU is the monitoring of human internal environment, and these blood tests can't be done at all because they all rely on machines.

Shooting, B-ultrasound and CT are definitely not acceptable.

What if the patient really needs surgery?

Then you have to go back to the Stone Age. The key is that the diagnosis is not clear, and I don't know what disease it is!

In the absence of CT examination, neurosurgeons can roughly judge the patient's brain injury and bleeding through the patient's limb movements and pupil reflex, but they can't make a diagnosis. You can only drill holes in the skull to test for bleeding. If there is blood stasis gushing out, it is the patient's luck. If not, we can only drill down the next one. Before drilling, the patient may have died, and surgery may even accelerate the patient's death.

Fortunately, because surgeons evolved from war doctors, a lot of first aid can still be done, although it may be a little rough.

For example, if there is no aspirator to suck blood, you can constantly wipe it with gauze. Without electrotome and electrocoagulation, ordinary scalpels will certainly bleed a lot, but they can make do. Brain surgery is more painful, because the requirements of hemostasis are high, and the blood vessels of brain tissue can not be ligated or pressed hard.

For the operation of bone cutting, there are no electric drills, milling cutters and other instruments, but hand drills, bone rongeurs, osteotome and osteotome can make do.

Then there is the suture of the wound, which itself does not require electricity.

Of course, those vascular interventions, endoscopes and endoscopic operations will definitely not be done. Because they need to see the lesion through the monitor, there is no electricity and there is no work at all.

The most difficult thing is definitely the anesthesiologist, because they need to accurately control the dose and constantly monitor the patient's condition as described before. If the anesthesia is a little deep, the patient may not wake up; The anesthesia was so shallow that the patient jumped with pain.

In fact, a very important problem caused by power failure is lighting. You said that the mobile phone flashlight can illuminate, not to mention whether the brightness is enough. Critical battery life is not enough. A few hours after the operation, the mobile phone will soon fail. At this time, if there is no candle, you can't see it. If candles are used, the light of candles can't meet the requirements of surgery, because most operations are in the deep part of the human body. A shadowless lamp, which is usually ignored by surgeons, now makes us unattainable!

Finally, there is good news to tell you that many of the machines mentioned above are actually rechargeable, which means that they can work for a while even if the power is cut off. This is for the transfer of hospital patients, but the problem is that the charges can only be managed for a short time and the number is limited.

In principle, if the hospital suddenly loses power, patients with mild illness will find a place to live, because only a few medical staff can watch the severe illness, take out the mobile phone lighting, pinch the ball, and all the treatment and medicine delivery will be manual. Operation is half done, don't be perfect, finish it quickly.

When it exceeds 1 hour, the problem comes. The rescue efforts are definitely not enough, and some critically ill patients who are already dying may not be able to persist.

If it takes more than 3 hours, very urgent patients will be light or heavy because they can't be examined and operated, even from serious illness to death, especially some elderly patients and newborns in incubators.

If it takes more than 24 hours, it must be a disaster. Most critically ill patients who rely on instruments can only rely on luck, and the doctor's energy and physical strength have reached the limit.

Having said so much at last, I hope this will not happen. Electricity is already the infrastructure in the infrastructure, and restoring the power supply in hospitals can save many lives.

Zhengzhou, hold on, come on!
