When a woman transfuses blood, the nurse takes out her mobile phone first! What is the reason why it returns to blood?

Silent moment. ? Recently, a woman in Bijie, Guizhou had a blood transfusion in the hospital, but when this happened, the nurse next to her actually took out her mobile phone and looked at it first. I really don't understand whether the nurse is calling someone or checking the blood back. What should I do?

Zhao Nvshi went to the hospital for infusion due to discomfort, but the nurse who gave the infusion forgot to take off the pulse pressure band on her wrist after inserting the needle, which led to the return of 20-30 cm of blood from the infusion tube. But in this case, the nurse next to her did not check Ms. Zhao's physical condition in time, but took out her mobile phone from her pocket and searched for something. After playing with her mobile phone, she pulled out the needle from Zhao Nvshi's hand. It is understood that it was the nurse who finally asked other medical staff to re-needle Zhao Nvshi, but Zhao Nvshi untied the pressure band himself.

What about blood transfusion? This situation is actually very common in clinic, because nurses hang so much water every day that it is impossible to keep an eye on the infusion situation of each patient. Generally, patients or their families are asked to call the nurse to change fluids or pull out needles after hanging water. Then sometimes patients or their families don't pay attention, and there may be cases where the liquid is lost without knowing it. Is it terrible to encounter this situation? Actually, there is nothing to be afraid of. Many people may have heard of gas embolism, fearing that air will enter blood vessels and cause pulmonary embolism. This situation will basically not happen. Clinically, there is basically no gas embolism, so don't worry.

In addition, why is gas unlikely to enter blood vessels? Because people's veins are also under pressure, we usually have systolic and diastolic blood pressure when we lower blood pressure, and the veins also have a certain pressure. When infusion, the infusion bottle should be placed on a very high infusion rack, and this venous pressure should be overcome by gravity. When the liquid is lost, the external pressure becomes smaller and the venous pressure becomes larger, so some blood will return, but not much, because it is still difficult to overcome gravity and run upward.

Conclusion: Don't be too flustered when you find that you forgot to turn off the liquid after infusion. Turn off the switch first, and then call the nurse to change the liquid, which has no effect on the body.
