A DOCTOR who allegedly refused to let a pregnant patient use his telephone to call an ambulance after she began vomiting and suffering severe stomach pains outside his clinic has been accused of professional misconduct. Yuen Lai-ting, 37, told a Medical Council inquiry yesterday she had visited Dr Frederick Man Pui-bor's clinic in Tseung Kwan O in August 1993. He diagnosed an ectopic pregnancy and told her to take a taxi to hospital immediately. But, a few minutes after leaving the clinic, Ms Yuen said she began vomiting and suffering severe pain and could no longer walk. Ms Yuen said: 'When I went outside I felt very dizzy and began to vomit. I was feeling great pain in my abdomen all the time.' Ms Yuen's friend, Leung Kam-ho, told the hearing she had left the sick woman with a passer-by and rushed back to the doctor's surgery to call an ambulance. Ms Leung said: 'I told the nurse my friend was sitting outside suffering severe abdominal pain, and that she could not walk and had vomited twice. 'But when I asked to use the phone to call an ambulance the nurse said she would have to consult the doctor and I heard him say I could not use it because it would be very troublesome and would hold up the phone.' Ms Leung eventually called an ambulance from a nearby restaurant and her friend was taken to hospital, where she was operated on for an ectopic pregnancy - a condition where the foetus develops in a fallopian tube rather than the womb. Dr Man's defence counsel suggested Ms Leung had asked to use his client's phone to call an ambulance before leaving the clinic with Ms Yuen but had been told by the doctor it would be better and quicker to take a taxi. But Ms Leung told the inquiry: 'My friend's condition got much worse after we left the clinic and it was only when I returned that I asked to use the phone to call an ambulance. 'Since the nurse was aware of my friend's condition, I thought it would be faster and more convenient to go to the hospital by ambulance rather than by taxi.' Ms Yuen told the inquiry Dr Man had called her to ask why she had launched a complaint against him. She said: 'He was very angry and told me I should have thanked him for diagnosing an ectopic pregnancy rather than complaining about him, but I told him I didn't want anyone else to be victimised by him.' The inquiry was adjourned but the defence counsel said Dr Man, who is accused of disregarding his professional responsibility to adequately treat or care for his patient, and his nurse would be called to give evidence.
