“She just wanted to sleep”: Taiwanese model dies after propofol ‘milk injection’ at beauty clinic

Did an unlicensed assistant and off-label drug use contribute to the death of model Cai Yuxin?

A Taiwanese model has died after being administered propofol—a powerful anesthetic known as the “milk injection”—to treat insomnia at a cosmetic clinic in Taipei, triggering a national scandal, criminal probe, and intense public backlash. Cai Yuxin, popular for her appearances at car shows, was pronounced dead after 18 days in a coma, following what authorities say was a fatal lapse in medical supervision and procedural compliance at Fairy Clinic.

The procedure was conducted by Wu Shaohu, a celebrity cosmetic surgeon nicknamed Taiwan’s “Godfather of Liposuction.” He is now under investigation for potential criminal negligence after allegedly delegating post-procedure monitoring to an unlicensed assistant. The Ministry of Health and Welfare has confirmed propofol’s classification as a controlled substance, warning that its use outside hospital settings is both dangerous and potentially illegal.

What led a prominent model to seek intravenous anesthesia for insomnia treatment?

Cai, known for her statuesque build and frequent appearances at automotive events, had shared with friends that she struggled with chronic insomnia. She was referred to Fairy Clinic by a friend for a procedure informally called the “milk injection,” referencing propofol’s white, opaque appearance. She arrived at the clinic on May 25 and was administered the sedative by Wu himself, who then left the premises.

What followed was a series of critical failures. According to United Daily News, the IV equipment was improperly set, causing a surge in flow rate. The assistant—lacking a nursing license—was reportedly left to monitor the patient, during which time Cai suffered cardiac and respiratory arrest. Wu was contacted by video call and guided the assistant in attempting CPR, but by the time emergency services arrived, she had no detectable pulse. Cai was hospitalized in a coma for over two weeks and removed from life support on June 12.

Why is propofol considered so dangerous outside of hospital environments?

Propofol is widely used in hospitals to induce sedation or general anesthesia during surgical procedures. Its short onset and potent effects make it highly effective—but also very risky. Mismanagement of dosage or administration speed can lead to respiratory depression and cardiac arrest. For this reason, Taiwan’s Ministry of Health and Welfare has listed it as a Schedule IV controlled substance, requiring continuous monitoring and administration by certified professionals.

Cai’s use of propofol for insomnia represents an off-label application not supported by sleep medicine guidelines. Experts stress that such a powerful anesthetic has no place in outpatient or cosmetic settings without hospital-grade monitoring. Anaesthesiologists across Taiwan have voiced alarm, describing the incident as preventable and reflecting broader issues in regulatory enforcement.

What legal charges and institutional failures are emerging in the wake of this incident?

Wu Shaohu is being investigated for violating the Medical Care Act and causing bodily harm through negligence. According to Taiwan’s Central News Agency, authorities are scrutinizing both the lack of medical personnel present during the drip and the absence of proper monitoring equipment.

The clinic itself may also face administrative penalties or even license suspension, depending on the outcome of ongoing inspections. Surveillance footage has reportedly gone missing, raising questions about evidence tampering. If proven, it could escalate the case beyond medical malpractice to obstruction of justice.

Public sentiment is also pushing for a systemic review of Taiwan’s cosmetic and elective medical sector. Though tightly regulated on paper, many clinics operate in a grey zone between cosmetic enhancement and clinical procedures, often without adequate oversight.

What parallels are being drawn to past misuse of propofol, including high-profile cases?

Medical professionals have compared Cai’s death to the 2009 passing of American pop icon Michael Jackson, who also died of propofol overdose under the supervision of a private physician. His doctor, Conrad Murray, was later convicted of involuntary manslaughter.

In Taiwan, this isn’t the first time propofol misuse has turned deadly. A woman died under similar circumstances in 2024 during a cosmetic procedure at a different Taipei clinic. At that time, regulatory authorities pledged tighter controls—promises that critics now say were not enforced.

This case underscores a pattern: a growing demand for elective procedures intersecting with lax regulation, celebrity marketing, and patients seeking fast solutions to chronic conditions like insomnia or anxiety.

Why are patient safety advocates demanding urgent reforms in Taiwan’s cosmetic sector?

Following the death of Cai Yuxin, there are renewed calls from health experts, legal commentators, and patient advocacy groups for significantly stricter oversight of Taiwan’s aesthetic medical sector. One of the primary proposals gaining traction is a total ban on the use of propofol in cosmetic clinics, with advocates arguing that such high-risk anesthetics should be strictly reserved for hospital environments.

In addition, there is growing support for making real-time patient monitoring mandatory during all sedative procedures, ensuring that any signs of respiratory distress or abnormal vital signs are immediately detected and addressed. Health regulators are also being urged to require detailed reporting and audit trails for every instance of controlled substance use within private clinics to prevent both misuse and cover-ups.

Another major demand is the imposition of criminal penalties for any unauthorized practice involving unlicensed or underqualified staff, especially in cases where such negligence results in serious harm or death. Collectively, these proposals reflect a rising consensus that Taiwan’s current system lacks the safeguards necessary to protect patients from preventable medical tragedies in commercial cosmetic settings.

Taiwan’s Ministry of Health and Welfare has already confirmed an internal audit of similar clinics, and more stringent inspection protocols are likely to follow. Meanwhile, doctors have issued public advisories warning against the use of intravenous anesthesia for non-clinical purposes.

What safer alternatives exist for treating chronic insomnia without resorting to anesthesia?

Insomnia is a common but complex sleep disorder with well-established treatment pathways. These include cognitive behavioral therapy for insomnia (CBT-I), prescription hypnotics with long-term safety data, and lifestyle modifications involving sleep hygiene and digital detox practices.

Experts warn that patients lured by celebrity endorsements or non-clinical recommendations are often bypassing safer, more sustainable care in pursuit of instant relief. The misuse of propofol in this context reflects a broader misunderstanding of sleep medicine and underscores the need for widespread public education campaigns.

What is the likely long-term fallout from this case for Taiwan’s health and cosmetic sectors?

Cai Yuxin’s death has sparked a reckoning—not only for the Fairy Clinic and Wu Shaohu but for Taiwan’s entire aesthetic medicine industry. As regulatory investigations unfold, many clinics may soon face tighter restrictions, increased compliance audits, and potential legal exposure for past conduct.

Moreover, the incident is expected to influence policy changes at the national level. Legislative proposals could soon make their way into parliament, particularly around controlled drug classifications, off-label use enforcement, and criminal liability for patient deaths linked to unlicensed care.
