Sedation and Conscious Anesthesia in Aesthetic Surgery: Safety Trends

In recent years, as the demand for plastic surgery and aesthetic procedures in Ho Chi Minh City has increased, concerns about safety have grown. Following reports by the media on incidents related to general anesthesia, many people are seeking lighter sedation techniques. Two terms that are becoming increasingly common in aesthetic consultations are regional anesthesia and conscious sedation (sedation, where the patient remains conscious or drowsy but not in pain). While these technologies are not entirely new, their application with a system and emphasis on anesthesiologist involvement is seen as a step forward towards safety for beauty professionals.

What is Regional Anesthesia and Conscious Sedation?

To better understand, let's differentiate three common levels of sedation in aesthetic surgery:

• Local anesthesia: Medications are injected directly into the small area requiring intervention. The patient remains fully conscious. Suitable for minor procedures such as blepharoplasty, liposuction, and microdermabrasion.
• Regional anesthesia: It numbs a larger body region (e.g., nerve block, local anesthetic). The patient is awake but does not feel pain in the surgical area.
• Conscious sedation: Using intravenous medications to relax the patient, reduce anxiety, cause drowsiness or light sleep, while still breathing and able to respond. Often combined with local anesthesia or regional anesthesia.

Unlike general anesthesia (losing complete consciousness, usually requiring endotracheal intubation and ventilatory support), the combination of regional anesthesia and conscious sedation keeps the patient in a milder state, with faster recovery.

Why is it considered a risk reduction trend?

The main reason why many anesthesiologists prioritize considering regional anesthesia and conscious sedation for suitable cases is to avoid some risks associated with general anesthesia:

• Reducing complications related to breathing and ventilatory support.
• Patient regains consciousness early, less nausea post-surgery, faster recovery, and better movement.
• Better pain control after surgery due to the extended effect of regional anesthetics.
• In many cases, shorter monitoring time for recovery, able to go home with suitable procedures.

It's important to note: this is a risk reduction trend, not a risk-free technique. Medical evidence shows that regional anesthesia and conscious sedation have good safety records in many procedures, but outcomes depend greatly on the correct choice of procedure, dosage, monitoring equipment, and team competence. No anesthetic method is absolutely safe for everyone.

Which procedures are suitable, which are not?

Regional anesthesia and conscious sedation are typically considered for moderate to minor procedures with short duration and localized surgical areas. Some common examples include facial surgery, eye contouring, nose shaping, and some mid-sized abdominal or pelvic interventions.

In contrast, general anesthesia remains a reasonable choice in the following situations:

• Large, lengthy procedures, multiple areas of intervention at once.
• Patients who are overly anxious, difficult to cooperate when conscious.
• Contraindications with regional anesthesia (e.g., bleeding disorders, infections around the needle insertion site, certain spinal conditions...).
• Underlying cardiovascular or respiratory conditions requiring active breathing control.

The choice of method cannot be determined online or through advertisements alone. It must be based on direct consultation, medical history evaluation, and necessary tests.

The Irreplaceable Role of the Anesthesiologist

A point often overlooked in aesthetics is the role of the anesthesiologist for recovery. Even with light sedation, patients still need continuous monitoring of blood flow, blood pressure, oxygen saturation levels, and responsiveness. Sedation may deepen unexpectedly, affecting breathing; in such cases, a well-trained and ready-for-emergency response team is necessary to handle it promptly.

A safe anesthesia process typically includes:

• Pre-anesthesia examination, risk classification before surgery.
• Monitoring and recovery equipment at the operating room standard.
• The specialized anesthesiologist monitoring throughout and after the procedure.
• Emergency plan for situations requiring method conversion.

This is also why beauty professionals should prioritize accredited facilities with operating rooms and recovery teams that meet the true definition of anesthesiology, rather than service points lacking emergency response capabilities.

Security Notes and Underlying Factors

Responding to different anesthetic medications and sedatives in each individual, depending on weight, age, underlying conditions, current medications, and genetic factors. Some people have a risk of drug allergy, drug toxicity if used at high doses, or abnormal reactions to sedatives. Patients with cardiovascular, respiratory, liver, kidney diseases, pregnancy, or anticoagulant use should be evaluated carefully. Therefore, fully disclose your complete medical history and current medications to the doctor. The results and level of safety depend on individual factors, not general experiences from others.

Readers should also be cautious of exaggerated advertisements like "absolute pain-free sedation," "exclusive proprietary technology," "100% safe," or "no complications." Claims without clear scientific evidence are warning signs. Sedation is a part of medicine, always accompanied by principles of evaluating benefits and risks, not a "trick" for marketing.

Dr. Vo Thanh Sang's Perspective

According to Dr. CKI Vo Thanh Sang, prioritizing regional anesthesia and conscious sedation for suitable cases is a positive signal, reflecting the mindset of putting patient safety first. However, no anesthetic method can replace the core: direct consultation, correct indication selection, execution at accredited facilities with specialized anesthesiologists. Dr. emphasizes that beauty professionals should ask clearly who will be responsible for anesthesia, if the facility has adequate monitoring and emergency response capabilities, and not to fall for "absolute safety" promises.
