💭 The concern: “What if I wake up during surgery?”

Have you ever had this concern while considering cosmetic surgery?

“What if I regain consciousness while under general anesthesia?”

This question is not uncommon and may sometimes come up during consultations.

In this article, we will explain what intraoperative awareness is, its incidence rate, the circumstances surrounding it in cosmetic surgery, and the points you should confirm before seeking treatment.

Having the correct knowledge is the first step toward easing anxiety.

Intraoperative awareness is a medically reported phenomenon, but
its incidence is extremely low, and cosmetic surgery in particular
differs in circumstances from specialized, severe surgeries.

🔍 What is intraoperative awareness?

Intraoperative awareness refers to a phenomenon in which consciousness partially returns during general anesthesia.

Rather than “opening your eyes,” cases have been reported in which patients partially hear sounds or voices, or regain some sensation.

However, the content and perception of the experience vary from person to person, and some cases involve pain while others do not.

✅ Patterns of awareness

Rather than fully regaining consciousness, most reports describe fragmentary memories of sounds or sensations. The content and degree of the experience vary from person to person.

📊 How common is it?

According to multiple research reports, the incidence of intraoperative awareness under general anesthesia is approximately 0.1–0.4%.

These figures vary depending on the research conditions and participants, and represent comprehensive data covering all types of surgery.

The following are examples of surgical situations considered to carry a particularly high risk of occurrence.

✅ Examples of surgeries considered to carry a relatively high risk

・Emergency surgery for severe trauma
・Cesarean section
・Cardiac surgery
These cases involve anesthesia management conditions that differ significantly from normal.

Routine cosmetic surgery differs from emergency surgery for critically ill patients.

※ The incidence rate varies depending on the reports and research conditions

🏥 Current Status of Anesthesia Management in Cosmetic Surgery

Currently, many medical institutions are implementing various measures to improve the safety of anesthesia.

✅ Examples of Commonly Implemented Safety Measures

・Use of anesthesia depth monitoring equipment
・Management by an anesthesiologist or attending physician
・Continuous monitoring using vital sign monitors

However, systems and equipment vary by medical institution.

We recommend confirming directly with the institution before your appointment what type of management will be provided.

※ The anesthesia method and its suitability will be determined by the attending physician

・Consult with multiple clinics and compare your options to broaden your choices

✨ Summary

Here is a summary of the key points to remember about intraoperative awareness.

☑ The incidence is relatively higher in cases involving special conditions, such as severe trauma and cardiac surgery

☑ Typical cosmetic surgery procedures differ from these situations

☑ Many medical institutions now have safety management systems in place, including monitoring of anesthesia depth
