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, and then affect the function of the digestive system, the recovery of physical strength; endocrine, hormonal effects, both directly and indirectly, make 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 characteristics of the large individualized differences in pain perception. Painkillers 1. Analgesics for pain: commonly used painkillers include morphine and pethidine. Intramuscular injection on the night of surgery has a good pain relief effect and helps the patient to fall asleep. Postoperative generally limit the use of 1 to 2 times, should not be used more, otherwise it is easy to affect the recovery of intestinal peristalsis and urinary function. 2, other painkillers: commonly used indomethacin suppositories (anti-inflammatory pain suppositories), administered through the anus, antipyretic and analgesic effect; flurbiprofen ester, intravenous drip; analgin, intramuscular injection; Tramadol class oral and so on. Attention should also be paid to the psychological adjustment of patients. Due to the special characteristics of the anorectal department, patients are afraid of surgical pain, and secondly, they are worried about the recovery of postoperative anal function. To address this feature, you can communicate with the doctor in advance to inform the views and requirements. At the same time, the doctor should give a detailed account of the condition to the patient and his family, explaining the general situation of the operation in a kind language and the possible discomfort during the operation in an appropriate language. For example, when ligation of internal hemorrhoids is done, some patients have a feeling of falling, as if the large intestine is going to fall out of the anus. At that time, we should be prepared for the patient’s feasible deep whistle, try to relax, can reduce the discomfort. Intraoperative communication with the patient, pay attention to the language of expression, more body language communication, should minimize, reduce the sound of surgical instruments, as appropriate, so that patients can see the cut tissue. When the operation is over, the patient is most eager to know the real situation of his operation and the effect of the operation. Therefore, the psychological adjustment of postoperative patients is the key to promote and ensure the smooth recovery of patients after surgery.
