A. Preoperative psychological assessment Before the operation, the doctor will conduct a psychological assessment of the candidate to judge the effect of the treatment after the operation. If the candidate’s expectation of the effect of the surgery is too high, the doctor will inform the possible effect. If no agreement can be reached after communication, the doctor will suggest to postpone the treatment. Pre-operative consultation The doctor should know in detail the allergic symptoms or allergic history of the candidate, allergic to certain drugs (including anesthesia), food, plants, cosmetics, etc., should be carefully considered whether to carry out the treatment. When there are wounds on the skin or infections such as multiple inflammations of acne, the doctor should discuss with the doctor whether it is necessary to suspend the treatment to avoid localized opportunistic infections at the surgical site due to minimally invasive wounds. At the same time should be clear about the candidate’s current use of medicines, especially certain blood-thinning drugs (anticoagulants), for people taking, for example, aspirin, ginseng, salvia, ginkgo, garlic, should stop taking a week before treatment, otherwise it is easy to cause bruising or bleeding at the injection site. In addition, candidates should inform the doctor of their medical records for the past six months, and if they have had facial plastic surgery, as well as cosmetic treatments such as lasers, ultrasonic scalers, and radiofrequency, the doctor will have to decide whether or not to proceed with the treatment on a case-by-case basis. In general, it is safe to receive hydrafacial injection six months after facial plastic surgery or photoelectric treatment. Prohibited include: 1, hypertension, heart disease, diabetes, malignant tumors and other serious diseases. 2, is using anticoagulants, blood activators, it is best to stop using a week after the application. 3.The presence of open wounds on the face due to surgery or trauma. 4.Severe acute, active skin infection. 5, known to be allergic to any component of the injection material or anesthetic. 6, Pregnancy, lactation. Prudent use includes: 1, allergic body, scar body with caution. 2, Facial capillary dilatation is obvious. 3, is in the allergic period, inflammatory reaction period with caution. 4, hormone-dependent dermatitis attack period. Third, cleaning and disinfection Remove make-up, clean skin, take pictures and record; in the injection site appropriate amount, uniform thick coating of anesthetic, and seal the package with plastic wrap, surface anesthesia, dressing anesthetic time for 30 to 60 minutes is appropriate, and then wash with water to clean the anesthetic; with medical alcohol for the body of the instrument and the skin contact parts of the disinfection; the treatment site with iodine volts by the center of the disinfection of the sides, disinfection of the 3 times with saline decoloration for 1 to 2 times. Attention: the operating doctor should wear surgical cap, medical mask, wash hands, wear disposable sterile powder-free gloves; use genuine instruments and needles, negative pressure catheter and disposable sterile injection needle must be changed by one person for one person, if there is a disinfection and cleaning is not in place should be immediately proposed to the doctor, and pause or terminate the operation. Intraoperative operation According to the interview situation and the needs of the candidates to configure suitable for the candidate’s nutrients. Turn on the switch, turn on the negative pressure, while checking whether the negative pressure is normal; connect the syringe and injection needle, the depth of injection will be adjusted according to the skin condition of the candidate, the optimal injection depth of 1.0 ~ 1.5 mm. The optimal injection depth is 1.0 to 1.5 mm. If the injection is too deep, it is easy to cause ecchymosis and pain; set the injection speed, injection mode, and setback value, etc. After the setting, push the syringe to check whether the medicine is evenly dispensed from each needle; usually inject in the order of jaw – cheeks and eye area – temporal area – forehead – nose. V. Post-operative care No need to wipe the blood after injection for slight oozing, and use sterile cotton swabs to gently wipe the blood for serious oozing. Apply refrigerated medical repair mask immediately after all the injections are finished, and can be combined with red/yellow light irradiation to relieve pain, eliminate erythema, improve postoperative satisfaction and shorten recovery time. Because the injection process briefly destroys the integrity of the skin barrier, making the skin more sensitive, and in individual cases, skin dryness or discomfort will occur, so the daily care of the skin is particularly important in the postoperative recovery phase, and need to carry out hydration and moisturizing care, while the attending physician will also be based on the individual condition of the candidate to develop a specific program. Tips: 1. Why do I need a psychological evaluation before surgery? Each person is an individual with different causes of disease, and of course treatment results vary from person to person. In terms of hydration, its main effect is hydration. But the reasons for dry skin are different for each person: there is a simple age problem, or simply do not like to drink water, there are also local climate differences, but also a variety of bad habits of the problem. For example, a candidate with good skin condition may be able to keep a single shot of hydrafacial for three months, while a candidate with poor skin condition may only be able to keep a single shot of hydrafacial for three weeks. If the doctor does not make a psychological assessment in advance and informs the patient of the possible results of the treatment, the patient is bound to be unbalanced. So when you meet with your doctor, ask yourself what is causing your dry skin so that he can give you the right treatment plan. In a word: for the safety of your surgery, more for your health. 2.Why do we need to take pictures before surgery, not for post-surgery publicity, right? First of all, as a medical worker, I understand your feelings. Often it is difficult to remember exactly what you look like before surgery, and many subtleties are often overlooked, so it is necessary to take a photo before surgery. The photos are kept as medical records to compare results before and after surgery, and are only for discussion and research between the patient and and the surgeon. Pre-surgery photo archiving is a routine practice, and there is a requirement to take photos before and after surgery. When taking photos, patients should be careful not to wear makeup, and record the original shape of the surgical site in the most realistic way. Surgical photography is conducive to comparing and observing the real results before and after surgery, and is a powerful safeguard for both doctors and patients. At the same time, people who have undergone plastic surgery will be overly concerned about the changes in their appearance after plastic surgery, and will often find some details that they had not noticed before, mistakenly believing that they were caused by the surgery. This can quickly ease your anxiety by simply pulling out your old archived photos and comparing them.
