An 80-year-old woman died at Sheba Medical Center after she was mistakenly infused with blood of an incompatible type, the Tel Hashomer hospital disclosed on Sunday morning. Sheba administrators immediately informed the Health Ministry, which will set up its own investigation committee to look into the tragedy. The woman, from the center of the country, arrived after midnight for emergency vascular surgery aimed at saving her two legs. But during the operation, "an unfortunate human error occurred" in which she was given a type of blood not compatible with her own, the hospital spokesman said. When the error was realized, efforts were made to resuscitate the patient for a long period, but they failed, and doctors had to declare her death. A statement was given to her family "in the transparency that characterizes the hospital," the spokesman said. Then the ministry and the press were notified. The hospital's own initial investigation suggested that an anesthesiologist failed to observe the required procedures. She has been suspended from all work at the hospital for two weeks. Sheba expressed its sorrow and condolences to the family.
