Doctors will have to make patients seeking liposuction wait 15 days to make sure they want to undergo the fat- removal surgery, under draft regulations published Monday, the dpa reported.
Liposuctions are the first aesthetic procedure to come under the scrutiny of Singapore's Health Ministry.
The complicated procedure has resulted in deaths, even in Europe, where it has been practiced for a long time, The Straits Times said. The only other medical procedure requiring a cooling-off period in the city-state is abortion.
"We think this period is useful," Health Minister Khaw Boon Wan was quoted as saying. "Otherwise, some operators might hard sell and force the customer to go and lie down and do it immediately."
Risks of cosmetic treatments have focused on general practitioners carrying out cosmetic surgery and other aesthetic procedures.
Khaw cited a case in Malaysia where a 40-year-old patient was left comatose following a tummy tuck performed by an orthopaedic surgeon and botched operations in Singapore that required follow-up surgeries to fix mistakes.
Under the new rules, the Health Ministry wants operations removing more than 1 litre of fat to be done in a hospital or surgery centre. Any amount less can be removed in approved premises.
Plastic surgeons said it is more common to remove between 3 and 7 litres of fat.
Physicians must have spent at least one year in surgery and acquired training in liposuctions to qualify for a licence to perform the cosmetic procedure.
The Singapore Association of Plastic Surgeons criticized the piecemeal approach to the regulations, which mocked the "comprehensive way bona fide plastic surgeons are trained."
No figures are available on the number of liposuction procedures performed in Singapore, but doctors said it runs into the thousands annually.
Doctors will have to keep track of their liposuction treatments when the rules take effect in a few months, the report said.
