Anesthetic technique improves quality of recovery for women having breast cancer surgery
Anesthesiologists using a technique similar to a dental freeze can improve the quality of recovery and decrease recovery time for breast cancer surgery patients, according to a new study. The paravertebral block technique uses ultrasound to precisely guide a needle to intercostal nerves reaching the breast and deliver local anesthetic to freeze these nerves. In total, five blocks are needed to freeze the five nerves involved. The freeze blocks the transmission of pain from the breast where surgeons can perform full or partial mastectomies, or even reconstructive breast surgery. At the same time, patients are given an intravenous drug called propofol which allows them to sleep through the surgery and continue breathing on their own, without needing a breathing tube or a ventilator.
