The left arm vein infusion is "harmful"?No scientific basis

Dahe Health News reporter Zhang Baofu correspondent Liu Xu Gang

Recently, the reporter saw a sudden death of patients with myocardial infarction in the WeChat circle of friends. The reason given is that the heart is on the left side, and the cool liquid enters from the left arm, which can easily cause myocardial spasm and even cause sudden death.

This argument, right? Is there a relationship between the sudden death of patients with myocardial infarction and the infusion of the "left arm"?

Is the left arm infusion "harm"? No scientific basis

"There is no scientific basis for the above statement." Wang Hongyu, the head of the Emergency Department of the Seventh People's Hospital of Zhengzhou, told reporters that in clinical work, medical staff will choose to infusion on the corresponding part according to the patient's condition. For patients with cardiovascular disease, doctors involved in the operating room generally choose the left arm in the right arm, and the infusion will choose the left arm; for traumatic patients, the health -side infusion is generally selected.

She said that the blood circulation of the human body, venous blood flowing out of capillary, flowing into the veins of various parts, and finally remitting the right atrium through the upper and lower cavity veins. Regardless of whether the venous infusion is the right arm or the left arm, the blood will eventually flow to the upper cavity vein, and then enter the right atrium. The entire cycle process is the same, and there is no problem with the distance from the heart.

Varicular infusion is all disadvantaged

"Intravenous infusion can quickly supplement the electrolytes and other substances in the body." Zhang Chaohua, deputy chief physician of the Department of Cardiovascular Medicine of Zhengzhou People's Hospital, said that intravenous infusion is huge in modern medicine and can quickly supplement the liquid and blood of the human body. It can sustain the constant concentration required for efficacy to play a role in eliminating bacteria and germs. In addition, drugs that are stimulating to muscle and subcutaneous tissue can be given through veins.

Of course, intravenous infusion also has some shortcomings. For the elderly groups with basic diseases such as poor heart function, the intravenous infusion drugs are excessive or too fast, which will add heart load and induce heart failure. If the operator is not handled properly, it may also cause patients to have a systemic or local secondary infection.

You need to eat before intravenous infusion

Zhang Chaohua said that if the disease needs to go to the hospital for intravenous infusion, try to eat before infusion to prevent symptoms such as nausea and panic after the drug enters the body. Before infusion, you must explain the actual situation of allergies, whether drinking alcoholism, etc.

During the intravenous infusion, patients should observe whether their skin is red, itchy, and whether there are adverse reactions such as panic, chest tightness, and shortness of breath. If adverse reactions occur, communicate with the doctor in time. In addition, do not adjust the infusion drop speed by yourself. Excessive infusion can easily cause infusion reactions such as fever and venousitis, and some special drugs, such as potassium chloride for hypokalemia, are too fast to cause arrhythmia.

After intravenous infusion, it is recommended to press for a short time to prevent bleeding. Do not leave immediately after infusion. It is best to observe the hospital for about 30 minutes to see if there is a delayed infusion reaction.
