We often encounter a small amount of air entering the blood vessels from the leather strip when we instill drugs intravenously. Many friends will be scared to death, thinking that air entering the body will lead to death. In fact, a small amount of air is It will not cause discomfort, because our blood itself can dissolve air, especially oxygen, a small amount of oxygen entering the blood will basically “disappear in a second”, and the nitrogen components in the air will also be washed away by the fast-flowing blood, The formation of tiny air bubbles will also be dissolved and absorbed in the process of traveling in the blood vessel, but if it is a large amount of air, be careful, it may lead to serious consequences, here is a real case.
A couple of days ago, a family member of a patient consulted me on the Internet. Her family member, a male patient, 34 years old, injected 300ml of air into her vein, and fainted on the spot. Fortunately, she was sent to the doctor in time. , The patient was rescued later, but the patient’s lungs were damaged, and the lungs showed interstitial changes, which looked like infection, but I think it was the performance of the blood vessels of both lungs being blocked by tiny air bubbles, and the heart underwent an electrocardiogram. It is found that there are signs of myocardial infarction. I don’t think it is necessarily related to air. It may be the performance of the body after being severely damaged, which is a myocardial emergency response. The patient was rescued in a timely manner. It is estimated that the injection was not so firm, and it may not be completely injected, so it was a blessing in misfortune that no death was caused.
