Different from the general bottle drip, the catheter placed in the deep jugular vein catheterization is directly connected to the patient's superior vena cava. During the infusion, the liquid directly enters the right atrium through the superior vena cava. Relying on the push of the heart,
The added fluid can be quickly distributed to various parts of the body. It is very beneficial for large-scale infusion and rapid rehydration. It enters the heart directly, and releases the drug to the whole body through the heart, avoiding the stimulation of blood vessels by high-concentration drugs as much as possible.
As for the possibility of left heart failure caused by rapid infusion... Replenishing blood volume as quickly as possible now will definitely relieve the pressure on Zhao Weihong's heart, rather than increase the load.
Doctor Zebra Glasses quickly completed the dispensing of fentanyl, and the micropump was connected to the previously placed catheter.
"One milliliter of infusion per hour is actually a bit too much for a sixty-seven-year-old person." Dr. Zebra pushed up his glasses. The sense of accomplishment in completing the work quickly gave him a desire to chat with others. In the operating room in the morning
When he was there, Dr. Zebra knew that Sun Lien was a graduate student, and he also intended to impart some relevant knowledge to Sun Lien. "According to general experience, patients over sixty years old must reduce their medication by half at the beginning, otherwise excessive opioid analgesics will cause
It causes depression of the respiratory center. But now that we have advanced airways and ventilators, this risk is actually not a problem."
As soon as Dr. Zebra connected the analgesic pump and the catheter, the nurse next to him immediately connected the prepared balance solution to the main inlet of the catheter. The regulator for adjusting the input was turned on to the maximum without even looking at it.
Let the balancing fluid flow into Zhao Weihong's neck vein along the pipe. In less than ten minutes, half of the 500 ml bottle of balancing fluid was gone.
If you were an ordinary person, you would have started sweating after such a heavy rehydration. But not only did Zhao Weihong show no discomfort, his heartbeat even dropped slightly.
"Continue rehydration and call the family members. Burns may require early skin grafting, and the family members must sign a consent form." Sun Lien breathed a sigh of relief. Zhao Weihong responded well to rehydration and analgesia. Although his age is difficult for recovery,
A decisive disadvantage, but fortunately, the burn wound area is not particularly large. The entire back accounts for about 13% of the total area of the human body. A third-degree burn on such an area is actually a blessing among misfortunes.
But the risk of burns on the back is equally huge. Unlike the chest and abdomen on the front, the tissue thickness of the back is actually quite limited. The fat layer under the skin that can play a certain insulation role is not as thick as the chest and abdomen. Moreover, the distance between the back and back is quite limited.
The vital organs of the body are actually closer, so back burns may sometimes cause more serious damage than they appear.
Zhao Weihong's family currently only has one daughter who is paying fees outside. Sun Lien, who has dealt with her, probably also understood that this family member was in some trouble. He lowered his voice and asked Liu Tangchun, "Teacher Liu, can you bring in another family member?"
"What to change? Do you want to change another patient?" Liu Tangchun was also a little helpless, "If the patient is this child, do you want to treat it or not?"
Sun Lien sighed, "Even out of humanitarian considerations, giving her a jugular vein catheter has reached the bottom line. If we do skin grafting without permission, the family will definitely make trouble."
"Let's make a fuss." Liu Tangchun gritted his teeth, and then his anger turned into a helpless sigh, "What else can I do? I'll go talk to her family. I hope this fire can clear her mind.
some."
Doctors from the burn department have already started preparations. The 13% area of skin grafting has exceeded the limit of autologous skin grafting. It is completely impossible to rely on the patient's own body for skin grafting. The only option at present is
Decellularized pig skin is used for artificial skin grafting using special materials.
Most doctors like pigs, especially the burn department and surgery department. The burn department needs to use pig skin to protect patients with large burns by skin grafting. Surgery is more direct, and the pig's heart, liver, spleen, lungs and kidneys are used for practice.
It is an excellent textbook. As for hepatobiliary surgery, it goes a step further. In the artificial liver support system developed by a team led by Academician Li Lanjuan, the main effective biological material, the pig liver cell hollow fiber tube, also comes from pigs.
The decellularized pig skin needs to be frozen and stored, and will be taken out for rewarming before use. This time is used to communicate with the patient's family.
Under the strong advice of Liu Tangchun and the police, the middle-aged woman called her husband. The man looked to be in his early fifties, wearing silver glasses, a black jacket, a white shirt, and no tie.
"What's going on?" His attitude was much better than that of his wife. After nodding towards the doctor, he pulled the middle-aged woman aside and asked in a low voice, "Didn't you say you took mom with you?
Have you eaten? Why are you burning like this?"
As if she had finally seen a savior, the middle-aged woman told her story while wiping her tears, "Our mother choked while eating, and a young man and his girlfriend helped..."
The two couples here were talking and passing by. Director Zang Fusheng of the hospital office just finished his overtime work and passed by the rescue hall. Seeing the huge battle here, he stood aside curiously and took a second look.
His eyebrows furrowed deeper and deeper. After a while, he suddenly tugged at Liu Tangchun's clothes and whispered, "Old Liu, this man seems to be the district chief Ouyang Hua of our district."
After listening to the first half of the story, Ouyang Hua nodded with some fear and said, "In today's social environment, it is not easy for young people to stand up and act bravely. Have you thanked me?"
The middle-aged woman said without changing her expression, her heart not skipping a beat, "Of course I'd like to thank you, but I'm just a decent person and didn't leave any contact information at all."
"What happened next?" Ouyang Hua continued to ask, "How did our mother get burned like this?"
"The old lady didn't want to stay in the hospital after she woke up, so I discharged her." The middle-aged woman continued, "When we were about to get home, my mother said that she had been feeling uncomfortable in her shoulders recently, had rhinitis, and had a headache.
I felt a little dizzy. I always heard people say that the health therapy near our house is very effective, so I took my mother to have it. The doctor said that rhinitis can also be treated with a small needle knife, as long as concentrated
Can it be good..."
Sun Lien, who was going out to ask for permission, happened to hear the part about the small acupuncture. He widened his eyes and directly interjected and asked, "The patient had a small acupuncture done? What part was it?"
The middle-aged woman who was interrupted was a little unhappy, but after all, she felt guilty for lying just now, and she didn't dare to act too arrogant in front of her husband, so she could only curl her lips and answer honestly, "Pricked through the nose.
."
"How long is that little needle knife?" Sun Lien asked, "How wide is it?"
"Is it about this long?" The middle-aged woman drew an outline that was about fifteen centimeters long. "The width...should be half a finger's width. After it was pierced to the end, my mother said that my nose felt quite comfortable."
