If a patient undergoes minimally invasive surgery to treat a disease, most of the patients do not have obvious pain, but due to the different sensitivity of each patient to pain, the symptoms that occur are not exactly the same, especially for pain-sensitive patients, the pain threshold is relatively low, and although effective anesthesia measures have been taken during the surgery, there will still be a slight sense of pain, which is not very intense and is generally within the tolerable range. If there is severe pain, the surgery will also cause some impact, especially when the pain caused by the attack, making it difficult to carry out the surgery, in this case also need to be timely treatment of complications, so for minimally invasive surgery patients, surgeons and anesthesiologists need to take certain measures to deal with the pain, so as to avoid the risk of occurrence.
