Thanks to anaesthesiologists like CHÉOS Scientist Dr. Alana Flexman, patients have comfortable, pain-free surgeries. Anaesthesiologists use medications that mute pain nerve signals being sent to the brain during operations. Dr. Flexman specializes in neuroanaesthesia, a sub-specialty focused on optimizing the conditions for surgery in either the brain or the spinal cord. A few of these procedures can actually be performed while the patient is awake!
