Surgery is one of the means used by modern medicine to treat certain diseases that are difficult to cure completely with drugs. In medicine and will be treated by surgery of various diseases and the nature of the urgency of the three categories: some due to the urgency of the condition, the need to be quickly implemented in the shortest possible time, otherwise there is a possibility of life-threatening, such as upper gastrointestinal hemorrhage, severe acute systemic trauma, etc., this type of surgery for emergency. Some other diseases such as various cancer radical surgery, has begun to use the medication preoperative preparation of hyperthyroidism pre-surgical thyroidectomy, etc., such diseases, although the time of surgery can be selected, but due to a variety of specific needs, it is not appropriate to too long postponement of the operation, which is known as the limited period of time surgery; the last category of surgical treatment, but the implementation of the operation sooner or later, without affecting the therapeutic effect of the range of plastic surgery within the scope of cosmetic surgery. Most surgeries, especially cosmetic surgeries, are elective surgeries, which not only allow for mutual communication and discussion with the operator, but also allow for the selection of the surgeon and the best time for surgery. When it comes to the time of surgery, the best time for elective surgery is usually chosen in the spring, fall and winter, except for emergency and limited term surgeries. As the temperature is lower, sweating is less, and the contamination of the surgical wound after surgery is relatively less than in summer, there are fewer factors of surgical failure caused by infection. However, it is not like some people say that summer can not be operated, because with the development of medical and health care, medical and health care equipment and environmental conditions are also improving, the development of antibiotics also play a very important role in the prevention and treatment of postoperative infections, the seasonal factors affecting the efficacy of surgery has become smaller and smaller. However, some surgeries still have their prime seasons. It is worth mentioning here is an emerging cosmetic weight loss surgery — liposuction. Its basic principle is in the fat accumulation of areas such as the abdomen, thighs, buttocks, etc. will be “expansion fluid” (saline, anesthetic and some other drugs) into the subcutaneous fat layer, so that the area of the expansion, the pressure increases, and then the subcutaneous deposition of fat (fat cells) through the vacuum negative pressure suction or ultrasonic vibration pumping out. Although this type of weight loss surgery is immediate, the surgical effect and postoperative local contouring still depends on the close adhesion of the skin to the subcutaneous tissue. Generally, the use of elastic bandage or high elasticity bodybuilding pants for half a year after surgery is required to promote the retraction and contouring between the skin. Often, some beauty lovers do not understand this and only look at the various beautiful fashions and sigh when the seasons change in the spring or even at the turn of spring and summer. Even if the surgery is very successful at that time, they still have to suffer from the “pain” of reluctantly wearing an elastic abdominal band or stretchy bodybuilding pants through the summer. Therefore, we need to remind those who want to perform liposuction for weight loss, to return your original face of the beautiful friends, fall and winter is the golden season for this operation, after the operation, with the help of thicker winter clothing to help you cover up a little, on the other hand, due to the lower temperature, with a close-fitting elastic abdominal belt is not too hot, to the next year in the spring and summer, take off the abdominal belt or elastic pants, just to put on all kinds of fashion to show your beautiful and colorful body shape! It will be a surprise to your family and friends.
