Many of the surgery in the field of cosmetic plastic surgery are day trips and I think that there are many relatively small scale cases of 1-2 hours. However, sometimes there are cases where you need to be systematically monitered after being hospitalized, with breast reconstruction, massive liposuction, or surgery using free tissue.
As mentioned in this blog before, patients need to stay away from blood thinning agents such as Vitamin E, fish oil, aspirin, etc., and during the surgery we use devices to prevent deep venous thrombosis by intermittently massaging instruments in the lower limbs.
When considering the risk factor of the patient side, factors such as age (65 years old and over), obesity index (30 or more), presence of smoking, presence of other basic diseases (diabetes etc.), etc. become a problem.
In addition, in case of surgical procedures for cosmetic purposes, when considering the balance between risk and benefit, it is required that the risk be lower than when treating disease.
Those things are difficult to understand for the general public, but since it is important to life, if you are planning for big surgery, please consult with your doctor once again.
