Surgeons at the Center for Transfusion-Free Medicine at Pennsylvania Hospital may implement advanced or minimally invasive surgical approaches to minimize blood loss or to conserve blood during bloodless surgery.

Surgeons may use methods such as using smaller tubes, limiting blood sampling, conducting multiple tests per blood draw or using medications or devices that control blood loss or enhance clotting.

Some examples include:

  • Cryosurgery: A method of removing or destroying diseased or abnormal tissue by freezing it using liquid nitrogen
  • Electrocautery or electrocauterization: A routine and safe procedure used in surgery to remove unwanted or harmful tissue or to burn and seal blood vessels which helps reduce or stop bleeding
  • Gamma Knife® radiosurgery: A method of brain surgery using a state-of-the-art machine that delivers a precise dose of radiation. The procedure is noninvasive, there are no incisions, no risk of infection or bleeding or other complications that come with cutting into the skull and exposing the brain.
  • Laser surgery: State-of-the-art laser technology that uses light beams to cut, burn or dissolve tissue which reduces bleeding as compared to traditional surgical methods
  • LigaSure vessel sealing system: An electrosurgical method of litigating and sealing blood vessels
  • Microwave coagulating scalpel: A device that uses microwave energy to cauterize or burn or destroy greater areas of tissue at one time
  • Robotic-assisted surgery: A minimally invasive surgery in which a physician operates robotic arms to operate and assist with surgery
  • Ultrasonic scalpel: A surgical tool that uses ultrasound waves to cut tissue and seal bleeding vessels at the same time which keeps blood loss to a minimum
