The news, reported by Taiwanese media last week, sparked controversy over the unregulated use of the anesthetic.

According to AM730, on 25/5, at a friend's suggestion, Cai visited the Fairy Clinic in Taipei for the "milk injection" therapy, administered by renowned cosmetic surgeon Dr. Wu Shaohu, the clinic's director.

"Milk injection" refers to treatment using propofol, a potent intravenous anesthetic that induces sleep quickly. It is typically used for anesthesia and sedation in clinical settings. The name "milk injection" comes from propofol's characteristic milky white appearance. The medical council stipulates that only specialized doctors may access and use propofol, and the procedure must be performed under strict supervision.

The United Daily News reported that after the injection, Dr. Wu left the room, leaving Cai under the supervision of a male assistant without a nursing license. An error in setting up the intravenous equipment caused the propofol infusion rate to increase abnormally. Consequently, a large dose entered Cai's body in a short time, causing circulatory shock. She suffered sudden cardiac and respiratory arrest.

The male assistant contacted Dr. Wu, who instructed him to perform CPR on Cai via video call. Dr. Wu returned to the clinic, but their efforts were futile; Cai's condition did not improve.

Cai was rushed to the hospital but remained in a coma for 18 days. On 12/6, her family made the difficult decision to withdraw life support.

Local authorities are investigating Dr. Wu for causing grievous injury by negligence and violating the Medical Care Act.

In Taiwan, the Ministry of Health and Welfare classifies propofol as a Schedule IV controlled substance. Regulations dictate that only qualified professionals can administer the drug, and its use must be strictly monitored.

Lai Xianyong, a Taiwanese anesthesiologist, stressed that clinics illegally using propofol to treat insomnia are violating medical ethics.

"These kinds of incidents occur annually, which is very unfortunate. Many medical staff are not properly trained in airway management but still perform propofol injections to treat insomnia. This puts patients' lives at risk," Lai said.

He advised those experiencing sleep problems to consult with sleep specialists for safe and effective treatment options, such as cognitive behavioral therapy, appropriately prescribed sleep medication, and lifestyle changes.
