An anaesthetist wants the city's top court to overturn a lower court's ruling that he was liable to compensate his patient - a surgeon - over injuries suffered after an operation. Frank Yu Yu-kai, 76, had surgery on his prostate and bladder, and a hernia procedure in May 2001. Chan Chi-keung was the anaesthetist. Within 12 hours, Dr Yu was unable to move his left hand or fingers. He is claiming he suffered nerve damage due to negligence. Dr Yu lost his claim in the Court of First Instance in November 2006, but the court held that he could be awarded about HK$1.67 million for loss of earnings if he was to win the case later. In October 2007, the Court of Appeal overturned the ruling. Yesterday, in the Court of Final Appeal, Dr Chan argued that he had properly applied a blood pressure cuff during the operations. Defence barrister Russell Coleman SC argued that the use of the blood pressure cuff did not constitute negligence. The five Court of Final Appeal judges reserved judgment.
