As soon as the early meeting was held, the urology department called to urge the patient. It probably means that the patient has stomach pain and needs surgery as soon as possible. Therefore, the operation planned an hour later started ahead of schedule.
In this emergency surgery, everyone moves quickly. After a while, the nurse took the patient into the operating room. On the side of the anesthesiology department, Dr. Li has also made all-round preparations.
As soon as the patient comes in, everyone swarms. Some drip, some stick electrode stickers, and some connect various wires. On the side of the anesthesia, he also held the medicine and waited for it to be ready.
Seeing that the IV was done and the vital signs on the monitor were generally normal, Dr. Li began to push the medicine.
However, a few minutes later Dr. Lee noticed something unusual. On the monitor, blood pressure drops at a rate visible to the naked eye. This drop, obviously, should not be caused by anesthetics.
Recall that the patient did not have high blood pressure and was not taking antihypertensive drugs! heart disease? Even more unlikely, the preoperative electrocardiogram and cardiac ultrasound were normal. Massive blood loss? Impossible!
Dr. Li quickly injected the patient with a vasopressor. Anyway, let’s get the blood pressure up first. This blood pressure does not give you any time to think.
The blood pressure was measured after taking the medicine, it was just about 80. Obviously, the normal dose boost is not obvious. However, this blood pressure is no longer so dangerous.
Anyway, put the endotracheal tube in first. There can be no problems with both breathing and circulation.
Meanwhile, he let go of both sets of drips. At the time, the fluid flowed into the patient like a thread.
After the catheter was fixed, the blood pressure still did not rise due to catheter stimulation. This means that the cause of low blood pressure has not been completely resolved.
Dr. Li was looking for clues when he saw that the urine bag he had just inserted was full of urine.
The almost exploding pee bag wasn’t the most shocking thing to him. He was shocked, how could it be released so quickly?
Subconsciously, he thought there must be something wrong. Carefully recall the bladder emptying operation process, this is clearly wrong!
Books have always told everyone that the bladder should not be emptied too quickly after intubation. One urination should not exceed 500 ml.
As there have been no problems, everyone is probably indifferent to this request.
What can cause the bladder to empty too quickly?
Sudden reduction of abdominal and pelvic pressure due to sudden contraction of the enlarged bladder. The capillary network, which is itself controlled by pressure, suddenly becomes unconstrained and expands. Therefore, it will manifest as hypotension. In some patients, the capillary network of the bladder wall may rupture and bleed.
If you have a heart attack, you can also trigger a cardiac event due to a sudden reduction in the preload and preload of the heart.
Dr. Li, who became more and more frightened, watched the changes on the monitor intently.
Seeing the blood pressure rise little by little, I feel really lingering in my heart. In his mouth, he couldn’t help complaining about the nurse who had just inserted the catheter. However, don’t be too harsh. After all, it wasn’t intentional.
I hereby remind everyone: Do not empty your bladder too fast! The amount of urination should be less than 500 ml each time!
