1. High professional requirements: Operating room nurses should have high professional knowledge and skills, including operating procedures, instrument use, postoperative care, etc. This requirement makes the training and selection process of operating room nurses relatively strict, resulting in a relatively small number of recruits.
2. Work stress and risk: The operating room is a high-pressure and high-risk working environment, and the nurses in the operating room should maintain a high degree of concentration and vigilance during the intense operation. This working environment puts forward higher requirements for nurses' psychological quality and emergency handling ability, and some nurses are unwilling to engage in this profession.
3. career development restriction: the career development path of nurses in operating room is relatively limited, and there is little room for promotion. Other nursing fields, such as emergency department and intensive care unit, provide more promotion opportunities and career development prospects, which also leads to a relative decrease in the number of nurses recruited in operating rooms.
