A nurse anesthetist, also known as a Certified Registered Nurse Anesthetist (CRNA), is a highly trained healthcare professional who specializes in administering anesthesia to patients undergoing surgery or other medical procedures. They work closely with surgeons, anesthesiologists, and other medical staff to ensure patient safety and comfort during anesthesia. To become a nurse anesthetist, one must first earn a nursing degree and gain experience as a registered nurse. After that, they complete a master's or doctoral program in anesthesia. CRNAs are skilled in monitoring patients' vital signs and adjusting anesthesia levels as needed throughout the procedure.
