Pain-free surgery from “violence” to “civilization”: In the past, surgery was done without anesthesia. In ancient Egypt, patients had to endure painful bone shavings to heal their wounds; “eunuchs” were tied up and held in place during surgery. The pain of the operation was far greater than the disease itself. Later, doctors found that patients who passed out from pain became very “good”, so doctors used “bloodletting fainting”, “clubbing dizziness”, or “drunkenness As a pre-surgical preparation, doctors use “bloodletting”, “clubbing”, or “drunkenness”. Often, some patients are not hit hard enough and wake up halfway through the surgery, struggling in pain; or they are hit over the head with a stick or bleed so much that they don’t need surgery anymore. Certain procedures were even creepier, such as hemorrhoid surgery, where the doctor used a blazing hot flat iron and pressed it against the hemorrhoid, and the patient wailed and ran straight ahead like a 100-meter race. This was the situation before the advent of anesthetics in the 1840s. In 1846, a dentist in Connecticut gathered journalists at the Massachusetts General Hospital to demonstrate the inhalation of “laughing gas” for pain relief, successfully allowing patients to enjoy “pain-free” surgery, which became a worldwide sensation. In 1847, British obstetricians administered inhalation anesthesia to women in labor and gave birth to a prince under anesthesia to Queen Victoria. The use of anesthetics brought surgical treatment to a new “civilized” level. We Chinese are proud that about a thousand years earlier than in the West, Hua Tuo had already used “Ma Bo San” to anesthetize patients and then perform caesarean sections, but unfortunately, there was no reproducible formula left for “Ma Bo San” that could be copied by future generations. Anesthesia is not “just a shot” In war, a large number of wounded people needed surgical treatment. At first, the patients were given “one shot” of anesthesia and then started to operate, but some of them screamed in pain when the knife fell. So, the physician played another one, not enough, and then another one, the results of good health, to pass, poor health will be a long sleep. Later, the doctor gave an anesthetic and then added “painkillers” to improve the quality of anesthesia. But still not solve some problems, such as some casualties of the whole body muscle stiff tension, after the operation can not close the stomach; broken muscle keys can not be sutured; tetanus patients closed teeth, breathing difficulties, and nothing can be done. In 1942, a military doctor saw South American Indians use a poisonous barrel arrow for hunting, and the arrow poison can make the prey’s whole body muscles weak and immobile. Chemists refined this poison and found that it was a “base”, which was the first “muscle relaxant” used in surgery, called “barrel arrow poison base”. The application of muscle relaxants solved many surgical problems, and also reduced the amount of anesthetics and painkillers. However, anesthesia accidents still occur frequently because of the great differences in the severity of the disease. After more than 150 years of exploration, eight monitoring methods have gradually become commonly used during anesthesia to monitor whether the patient’s vital signs are in a safe range throughout the whole process: heart rate and rhythm (electrocardiogram), blood pressure, respiration, oxygen concentration (oxygen saturation), end-expiratory carbon dioxide concentration, drug concentration, degree of muscle relaxation, and brain function. A peaceful sleep and painless organ replacement The Bible says that after God created Adam, he felt that Adam was too lonely and wanted to create a mate for him. So God let Adam sleep and then took a rib out of Adam’s body and molded it into a human form, called Eve. Today, on the video of the surgical control center, we can witness a real painless surgery: a child with an overgrown foreskin needs to be removed and resists the injection because he is afraid of pain, so the physician gives the child a few milliliters of liquid (anesthetic). After a few minutes, the boy fell asleep quietly and was smoothly sent to the operating room for the injection and surgery. Shortly afterwards, the surgery was successfully completed and the child awoke with his parents by his side. Another patient, who needed heart surgery, was lying on the operating bed, and the anesthesiologist comforted her while giving her oxygen (with anesthetic gas) from a mask, and she soon fell asleep. The next injection and urinary catheter were administered painlessly. When she woke up, the heart parts had been replaced. Lying in the post-operative ICU, she did not feel any pain from the surgical incision, because the patient had a small bottle (analgesic pump) with her, and the analgesic was injected into her body in small amounts and evenly, and she could control the amount of analgesic according to her pain needs. Examination and treatment without pain, lumpectomy, minimally invasive without incision, the past need to open the chest, the doctor can reach into the patient’s body to remove the lesion; now open three finger-sized holes, into a soft and thin camera tube, the other two small holes into the thin clippers, through the camera tube out of the video under the field of view of the operation, you can remove the gallbladder, pulmonary blisters, ovarian cysts, etc.. Today, the hospitalization time is shortened from more than 10 days in the past to 1 to 2 days. 1. In the obstetrics and gynecology department: the “conscious analgesia” procedure uses propofol plus painkillers, and painless abortion is performed under monitoring; the technique of painless maternal delivery has been applied for more than 10 years. 2.Endoscopy room: “conscious sedation” (imipramine) to complete painless gastroscopy, enteroscopy, fibrinoscopy, etc. 3.Imaging department: patients with trigeminal neuralgia are treated with radiofrequency, thermal cauterization is extremely painful, and after using propofol, the treatment is painless. 4.Emergency room: “painless skin test method”, patients do penicillin skin test, no longer “ow”. 5, health examination room: a spray tube to the blood sampling site “squeak” two, disinfection plus local anesthesia, eliminate the pain of the needle. 6, internal medicine: in 2005, foreign countries launched a “micro-needle”, diabetic patients inject insulin every day, the discomfort is only equivalent to the feeling of mosquito bites. 7, pain department: pain relief patch (fentanyl) for mild pain patients to facilitate pain relief. The “needleless injection” medicine box and long-acting analgesic pump launched abroad are controlled by computer chip, which can give pain relief medicine to various pain patients according to their needs. Warm tip: Pain-free technology requires prescription by relevant professional physicians, and the above eight monitoring techniques must be applied when implementing to ensure patient safety.
