For a long time, people think that postoperative pain is natural and unavoidable, and they just suffer in silence from postoperative pain. In fact, pain is controllable and can be reduced or made painless by drugs or tools. Pain is an undesirable stimulus that can cause a series of pathophysiological changes in the body, such as the effect on the autonomic nervous system of the body: accelerated heart rate, shortness of breath, blood pressure; mental changes leading to irritability, depression, followed by the impact on the function of the digestive system, the recovery of physical strength; endocrine, hormonal effects, both directly and indirectly, so that a variety of bodily functions change. Anorectal surgery patients are also often worried about postoperative pain, and some of the patients who are sensitive to pain are even more so. In fact, with the progress of science, more and more postoperative analgesic measures, the patient’s pain has been greatly reduced compared to the past. Today we will give you an introduction to several common postoperative analgesic measures. Analgesic Pumps Analgesic pumps, a liquid infusion device that keeps a stable concentration of medication in the bloodstream, can help achieve better analgesic treatment with less medication. The patient is usually allowed to press to add an additional dose to the continuous infusion, so treatment is more individualized, in line with the wide variation in pain perception. Pain medication Analgesics for pain The commonly used pain medications are morphine and pethidine. Intramuscular injection on the night of surgery is effective for pain relief and helps the patient to sleep. After surgery, the use of morphine is generally limited to 1 or 2 times, and should not be used more often, otherwise it will easily affect the recovery of intestinal peristalsis and urinary function. Other analgesics commonly used are indomethacin suppositories (anti-inflammatory pain suppositories), administered through the anus, with good antipyretic and analgesic effects; flurbiprofen ester, intravenously; analgin, intramuscularly; tramadol, orally, and so on. Advantages of postoperative analgesia 1, reduce the patient’s pain and discomfort, relieve anxiety, improve sleep; can let the patient in a more comfortable state through the postoperative stage; 2, eliminate the reluctance to deep breathing and coughing phenomenon caused by pain, improve the whistle, promote the discharge of sputum, reduce lung infection; 3, reduce pain, prompt the patient to get out of bed early activities, early functional exercise, reduce the risk of prolonged lying in bed leading to deep venous thrombosis; 4, block the sympathetic pain, promote patients early activity, early functional exercises, reduce the risk of deep venous thrombosis 4, blocking sympathetic overexcitation, eliminating tension, dilating blood vessels, improving microcirculation, thus promoting wound healing and accelerating postoperative recovery; 5, inhibiting sympathetic activity, promoting gastrointestinal peristalsis, and helping to restore gastrointestinal function after surgery; 6, reducing hospitalization time and saving costs by reducing complications and accelerating recovery. Side effects of postoperative analgesia The main side effects of postoperative analgesia are skin itching, nausea and vomiting, urinary retention, and drowsiness and dizziness in some patients, but these side effects can be controlled or avoided through appropriate treatment, and compared to postoperative pain, the majority of the patients with side effects of analgesia are acceptable. In addition, because of some opioids in analgesics, some patients are worried about whether they will become addicted, which is completely unnecessary, because it is a purposeful short-term continuous medication, and the dosage and usage has a strict procedural norms, and more importantly, the recipient is the patient in need of treatment, which is a reasonable and safe use of medication!
