Cardiovascular diseases are among the important health problems due to their increasing frequency and extensity in developed and developing countries. The most common method of treating cardiovascular diseases is Coronary Artery Bypass Graft (CABG) surgery. Common pain, sleep problems, and anxiety after CABG surgery can cause delay in postoperative recovery both physically and mentally. The study was planned to evaluate the effect of lavender oil inhalation on pain, anxiety level and sleep quality after CABG surgery.
