What is the reason for the cold chest during infusion

When you are sick, intravenous infusion can help your body recover faster. But everyone also knows that intravenous infusion actually causes some discomfort symptoms. Some people experience a cold chest when receiving an IV. So, what does it mean when the chest feels cold during infusion? In fact, this is mainly because the infusion liquid is relatively cold, and is generally stored in a cold storage to maintain its efficacy.

1. The hazards of infusion let you know the misunderstandings of infusion

Do not adjust the infusion speed at will

"In the infusion room, we often encounter patients who feel the infusion speed is slow because they are in a hurry to go home to cook or pick up their children from school, so they adjust the infusion speed themselves. In order to speed up, some patients will ask the nurse to hang the infusion bag higher or replace the small needle with a large needle. This is actually very unsafe." said the head nurse of the emergency department.

"Many of the patients receiving infusions in our hospital are elderly people with poor physical fitness and sometimes some heart problems. We must pay attention to controlling the drip rate during infusion. The infusion rate for children and people with weak bodies should not be too fast. Generally, adults should receive 40-60 drops/minute and children should receive 20-40 drops/minute. If the infusion rate is too fast, it will easily increase the burden on the heart and cause adverse reactions such as heart failure or pulmonary edema."

Many people think that adjusting the infusion speed is enough. In fact, there are some requirements for adjusting the infusion speed. Of course, the slower the infusion speed is, the better. Some drugs require rapid dripping during infusion. Rescuing patients in shock who are severely dehydrated or have lost too much blood should be quickly rehydrated, usually with several thousand milliliters of fluid entering the body every hour. Mannitol is used in ophthalmology to lower intraocular pressure. In order to achieve the therapeutic effect, the infusion speed must be increased, and a large needle will be used when the drip rate is increased.

In short, if you want to adjust the speed during infusion, you should first ask the medical staff and tell them your feelings and needs, and they will adjust it as appropriate. However, you cannot adjust the drip rate at will to avoid affecting the treatment. If you experience any discomfort such as palpitations or heart palpitations, you should press the bell in time to signal the nurse and doctor so that they can take measures to alleviate the adverse reactions as soon as possible.

Skin test drugs have expired and need to be redone

Some drugs are prone to cause allergies and require skin tests, but passing the skin test does not mean that you can safely give the drug an infusion. These drugs have a certain effective period. If continuous infusion is used, the time needs to be strictly controlled to avoid exceeding the effective period of the drug.

For example, penicillin is effective within 24 hours after infusion, but if it exceeds 24 hours, the allergy test must be repeated. This means that if a patient receives penicillin for two consecutive days, and gets it at 9 o'clock on the first day, then he has to rush to the hospital before 9 o'clock on the second day.

Avoid fasting during infusion

If you experience dizziness, nausea, pale complexion, or other discomfort during infusion, in addition to the disease you suffer from, it may also be an adverse reaction caused by infusion on an empty stomach. Li Yongping, chief physician of the emergency department of Jiangsu Provincial Hospital of Traditional Chinese Medicine, said that people's metabolic activity is often weak when they are fasting. At this time, infusion can easily activate the body to produce a series of physiological changes, such as increased heart rate, increased blood pressure, and rapid breathing.

Infusion on an empty stomach can cause nausea

In addition, if the patient has poor appetite and physical condition, it is easy to cause symptoms such as dizziness and nausea, and even cause hypoglycemia, resulting in pale complexion, rapid heart rate, cold sweats, etc. Infusion on an empty stomach may also induce or aggravate adverse drug reactions. For example, drugs such as penicillin, erythromycin, and azithromycin are prone to adverse reactions to the gastrointestinal tract.

Director Li Yongping emphasized that it is necessary to eat before infusion. Children, elderly patients, the frail and sickly people, and patients with diabetes, hypertension, coronary heart disease, stroke, etc. should be especially careful not to receive infusion on an empty stomach. If you are not eating, be careful to slow down the drip rate during the infusion.

Some medicines can cause pain

Sometimes, during an infusion, you may feel some pain in the blood vessels near the needle, which may be related to the medicine you are receiving. Some drugs, such as potassium chloride, will stimulate blood vessels and cause pain, while dripping levofloxacin may cause some redness along the blood vessels. In addition, the effect of the drug is closely related to the individual's physical condition. The effect of the same drug on different patients may be different. When the same patient receives continuous infusions, the condition may change at any time, so you must go to a regular hospital for infusion.

There are also some rules for pressing after removing the needle.

We occasionally encounter this situation when we are receiving an infusion. Everything is normal during the infusion, but not long after the needle is removed, bruises appear near the needle eye. Many people think that there was something wrong with the nurse’s operation and the needle was not removed properly. In fact, you are pressing in an incorrect way.

Where should you press after an infusion? Is there any need to ask? Of course, you should press the needle hole. I believe most people think so. But that’s not the case. During intravenous infusion puncture, the needle hole on the epidermis and the needle hole on the blood vessel are not at the same point. The distance between the two is related to the needle insertion angle and the thickness of subcutaneous fat. What we normally see with the naked eye is only the needle hole on the epidermis.

Therefore, when removing the needle, the cotton pad needs to be pressed straight on the blood vessel parallel to the blood vessel, so that the epidermal needle hole and the blood vessel needle hole are pressed at the same time. The pressing time is also important. The best time is 5 minutes. Do not stop pressing and move around freely after the needle is removed. This can effectively prevent bleeding or bruising on the local skin and subcutaneous tissue.
