First of all, we usually get injections through intravenous injection. Venous blood returns to the heart from the whole body. If air enters our heart through the blood, bubbles will be generated after the air mixes with the blood due to the pulsation of the heart. Because the blood cannot effectively pump blood from the heart, it may cause ischemia of the organs. The gas that enters the pulmonary artery or cerebral artery may also cause pulmonary infarction or cerebral infarction . But talking about harm and not dose is a hooligan. Generally speaking, air greater than 0.02ml/Kg enters our blood, which will make people feel uncomfortable. At this time, you may experience hiccups and coughs. If air exceeds 2ml/Kg enters the human body, the risk of pulmonary embolism, cerebral embolism, or sudden death of may occur. According to this standard calculation, an adult with 50 kilograms needs to inject 100 ml of air into the body. The probability of such extreme situations is very small. You need to send a bottle of potion cleanly, and the potion in the plastic tube and the drop bucket has been poured. At this time, you did not tell the nurse, and the nurse changed you a new bottle of potion without asking anything, so that the air in the plastic tube is pressed into your blood vessels by the potion behind. At this time, you have to check whether the air content in the control is sufficient.
But there are still cases of death due to air injection. In 2009, the forensic department of the Beijing Public Security Bureau published a case report in the magazine "Chinese Forensic Science", which detailed how a man committed suicide with an air needle. At the beginning, he used an injection on his chest with an injection, but obviously his technique was not accurate. He did not penetrate his heart, and then turned to his stomach. After nine injections, he still did not penetrate the blood vessels. Finally, after seven injections on both sides of his thighs, he finally found the blood vessels and injected him with about 400 ml of air crazily. Later, he felt discomfort. In the end, due to cerebrovascular infarction, the heart, liver, spleen, lungs, kidneys and pancreas were all entered by air, and multiple organs were embolized. What is the concept of
400ml? It is about a small bottle of mineral water. Although the injection of the potion will not have much impact on your health, it is better not to use your phone to brush your phone when you get an injected injection, or ask someone to accompany you to get a drip and help you pay attention to avoid letting the air enter our blood vessels.
