What is a Pain Pump?

Analgesics refer to drugs that can partially or completely relieve pain. There are two types of non-steroidal anti-inflammatory drugs and central analgesics. Common analgesics include aspirin, Qutong tablets, paracetamol, butepine, rofecoxib and the like.

There should be moderation when taking painkillers. If you take painkillers blindly and prematurely, although the pain can be temporarily relieved, it will not be conducive for doctors to observe the condition and determine the affected area, because it will cover the painful area and nature after taking painkillers. Doctors diagnose correctly and treat promptly.

Significance of painkillers

Pain not only affects the quality of life, but also causes mental illness due to chronic pain not being effectively treated. Many pain patients are not treated in time, so that the local long-term general pain is transformed into complex local pain syndrome or central pain, which becomes a refractory painful disease. Therefore, pain should be relieved in time.

Misunderstanding of painkillers

Some pain taking painkillers will actually cover up the actual condition. Many pains, especially those of the internal organs, make it difficult for patients to discern what went wrong. If you take painkillers prematurely, although you can relieve the pain temporarily, it will not be conducive to the doctor to observe the condition and judge the affected area, and it is not conducive to the correct diagnosis and timely treatment of the doctor. In addition, after taking analgesics, the patient temporarily feels no pain, but the disease may actually worsen, such as major bleeding in the ectopic pregnancy, secondary necrosis and perforation of appendicitis. This temporary analgesia will mask the actual condition and make the disease develop. Aggravated with serious consequences. Therefore, once the pain caused by the disease or pain of unknown cause occurs, the patient should go to the hospital in time to find out the cause of the pain.

There is also a misunderstanding of the side effects of analgesics: Some people think that occasional, low-dose analgesics will not harm the gastrointestinal tract, but they are not. Studies have shown that healthy people can develop gastric mucosal damage 16 minutes after taking aspirin. Similarly, studies have shown that single or low doses of non-selective non-steroidal anti-inflammatory drugs can cause upper gastrointestinal bleeding and perforation. Some people think that taking analgesics or topical analgesics after meals will not damage the gastrointestinal tract, and this concept is also wrong. The non-steroidal anti-inflammatory analgesic damage to the gastrointestinal tract is divided into two parts. One is the local irritation caused by the drug staying in the stomach. This can be relieved by taking it after a meal or using an external analgesic. However, more than 80% of the effects of analgesics basically affect the gastric mucosa through blood circulation. This kind of harm cannot be avoided by taking medicine after meals and using external analgesics.

Analgesics use principles

Painkillers on time

Analgesics should be given on time according to the degree, regularity of the pain, and the first effective analgesic period to maintain the concentration of the drug in the blood and control the pain stimulus below the pain threshold.

Painkillers

Generally, non-opioids are used first. If the drugs, doses and usage do not achieve analgesic effects, weak opioids can be added. If the combination does not relieve pain, strong opioids can be used.

Analgesics

For moderate and severe pain, it is best to use more than two analgesics, which can reduce their dosage and complications and enhance the analgesic effect.

Painkillers alternate

Repeated use of the same analgesic drug for a long period of time will cause drug resistance in the body. You should not rely on increasing the dose to achieve analgesic effects. You should switch to other analgesic drugs in time.

Painkiller drug dose

According to actual needs, under the premise of ensuring safety, the dosage of the drug is from small to large, until the patient stops pain. For example, you can't wait for the illness to be healed immediately, and increase the amount of medicine without authorization; or don't take medicine seriously, think of it and eat it, forget it, or take the medicine twice and take it once, which is wrong.

Actively prevent and prevent the side effects of painkillers.

The third category: narcotic analgesics. It is represented by opioids such as morphine and dulentin. These drugs have a strong analgesic effect, but long-term use can be addictive. These drugs have a strict regulatory system and are mainly used for patients with advanced cancer.

The fourth category: antispasmodic analgesics. It is mainly used to treat cramping pain in the gastrointestinal and other smooth muscles, such as gastrointestinal, biliary, and urinary angina. Representative drugs are atropine, probencin, belladonna tablets, and anisodamine.

The fifth category: anxiolytic analgesics. Patients with headache are often accompanied by anxiety, nervousness, and anxiety.

3. Prevent drug resistance: Patients who have been using analgesics for chronic pain will have drug resistance problems. At the same time, the longer the medication, the greater the dose of medication required, and various adverse reactions will follow. The methods to prevent or reduce drug tolerance include: comprehensively using auxiliary drugs as much as possible to enhance the analgesic effect; alternately applying different types of analgesics instead of using only one drug; gradually adjusting the drug dose after the patient's pain is relieved, The interval between medications can also be appropriately extended; at the same time, it can be treated with other analgesic methods.

4. Beware of gastrointestinal adverse events: Taking painkillers, especially non-steroidal anti-inflammatory analgesics, may cause gastrointestinal adverse events such as indigestion, nausea, ulcers and even perforation and bleeding. Patients who need to take non-steroidal anti-inflammatory analgesics for a long time and patients with gastrointestinal risk factors should choose as far as possible a selective COX-2 inhibitor that is relatively safe for the gastrointestinal tract, that is, selective non-steroidal anti-inflammatory analgesics , Such as celecoxib and so on.

5. Do not drink before or after oral painkillers: alcohol can increase the toxicity of painkillers, even regular doses can cause liver and kidney damage.

6, countermeasures for adverse reactions: some painkillers may produce certain adverse reactions, especially narcotic analgesics, which can show nausea, vomiting, acid reflux, indigestion, constipation, headache, dizziness, rash, shortness of breath, etc. The use of this drug should be stopped in a timely manner, and the physician should be instructed to replace other drugs to avoid aggravating the condition and causing other adverse consequences.

7. Only use heroin or morphine when you have severe pain.

Painkiller abuse hazards

1. Damage the kidneys. Analgesics can cause chronic interstitial nephritis, renal papillary necrosis, and renal insufficiency. This is because painkillers inhibit the synthesis of prostaglandins. More common indomethacin.

2. Induced gastric ulcer. Salicylic acid, aspirin, indomethacin and other drugs can stimulate gastric mucosa, cause severe gastrointestinal reactions, induce gastric ulcers, and even gastric bleeding and perforation.

3, bleeding tendency. Salicylic acid and aspirin can inhibit the formation of prothrombin in the liver, reduce the content of prothrombin in the blood, and also affect the physiological functions of platelets, prolong the clotting time, affect the coagulation function, and cause bleeding. tendency.

4, lead to leukopenia. An Naijin, Baotaisong, and indomethacin can inhibit the decrease of white blood cells caused by bone marrow, and even lead to agranulocytosis.

5. Liver damage. Aspirin, Baotaisong, and indomethacin can cause liver damage with liver enlargement and discomfort in the liver area. Elevated transaminase and other symptoms.

6. Allergic reactions. Analgin, paracetamol can cause allergic reactions, rash, drug fever, or exacerbation of asthma.

7, the use of indomethacin can appear central nervous system symptoms, such as headache, dizziness and so on.

8. Cover up the symptoms. After the application of analgesics, the condition can be covered up, the diagnosis is delayed, and the treatment time is delayed.

Celecoxib

It can effectively treat a variety of common acute and chronic pains. It is the first selective COX-2 inhibitor approved by the FDA and the largest non-steroidal anti-inflammatory analgesic in the world. Because it only inhibits the cyclooxygenase COX-2, it does not affect the protective effects of the prostaglandins produced by COX-1 on the gastrointestinal tract and platelets, so it has significant advantages in terms of gastrointestinal tract safety.

Luotongding

Other drugs

Common Narcotic Analgesics
