Chapter 864 (1/2)

”President Guo...” Xu Wei called Guo Xiang back, but found that she was still staring at the old man's feet.

”What's the matter?” Xu Wei asked.

”How did you get this injury?” Guo Xiang pointed to the scab of a small wound on the old man's calf.

”Well, I helped a friend move a few days ago. I was accidentally pierced by a nail on the furniture. I painted red potion when I came home. It's nothing. I didn't care about it.” Said the aunt.

Several people looked at each other and said, ”tetanus?!”

Think again, the old man's facial muscles are tense, unable to bite food and swallow. It's really a symptom of tetanus.

”Didn't you break the cold needle?” Asked Guo Xiang.

”I didn't fight. I didn't expect so much. I always bumped and had some small injuries in the past. Nothing happened...” the aunt said with a little annoyance. No one thought that such a small injury would get tetanus this time.

Tetanus is caused by the exotoxin produced by Clostridium tetanus invading the wound. Soil and rust are easy to be attached to Clostridium tetanus, so if you are injured outdoors, you are easy to be infected with tetanus.

Especially in deep and small wounds, Clostridium tetanus is particularly easy to reproduce.

Because Clostridium tetanus is anaerobic bacteria, what is anaerobic bacteria is that it is particularly easy to survive in an anaerobic environment and has strong reproductive ability.

Some open wounds are not so easy to get tetanus.

Small and deep wounds promote the growth of Clostridium tetanus because oxygen is not easy to enter.

So if there is a wound, it's best to wash it with hydrogen peroxide and then break the cold needle.

Otherwise, Clostridium tetanus will multiply rapidly, and then secrete exotoxins, mainly spasmodic toxins, which are absorbed into the spinal cord and brain stem, so as to enhance nerve excitability, tension and spasm of voluntary muscles.

The old man's inability to open his mouth and swallow is a spasm of thigh tension. If it is serious, respiratory muscle tension will lead to asphyxia.

During the discussion, the old man over there had a shortness of breath and the whole person twitched.

”Come on, get on the ventilator and enter the ICU!” Guo Xiang rushed over.

The old man was pushed into ICU, Guo Xiang and they began to rescue.

”Can it be diagnosed?” Xing Ming hesitated. Although all symptoms can be matched, Clostridium tetanus has not been found.

”It's too late to do bacterial culture. First suit the remedy to the case.” Guo Xiang said.

In fact, the diagnosis of tetanus mainly depends on trauma and symptoms, because bacterial culture can not be cultivated sometimes.

There are mainly wounds and typical symptoms, namely muscle spasm and angular tension.

Angle bow is like a bow, but the whole person is back up, like a reverse bow. If you have seen the zombie film, you may think that some zombies in the film will twist their whole body into an incredible arc, which is a bit like that.

Now the treatment is mainly tetanus antitoxin and immunoglobulin.

In addition, a large number of sedatives and muscle relaxants are used to relax people's muscles.

The old man's respiratory muscles are too tense to breathe. The oxygen trachea can't be inserted. He can only cut the trachea and connect the ventilator directly to the trachea.

The aunt was scared to cry outside and fell to the ground with a frightening white face.

On the other hand, cut the wound on the old man's leg to restore the aerobic environment and prevent the continued reproduction of Clostridium tetanus.

After all this, the old man was still in a coma.

In the next few days, the situation was good and bad, and the muscle spasm was relieved to a certain extent, but perhaps because the old man was old and his organs had been damaged, the situation was not very good.

The old man's children also came back from other places.
