Surgical nurses are nurses who specialize in surgical care. They play an important role in the operating room and surgical ward. In the operating room, the surgical nurse is responsible for preparing the operating room equipment and instruments, assisting the doctor in the operation, and ensuring the safe and smooth operation process. They are also responsible for monitoring patients' vital signs, providing necessary drugs and fluids, and handling postoperative wound care and postoperative recovery. In the surgical ward, surgical nurses are responsible for the care and supervision of patients. They will observe the changes of patients' condition, provide medication and wound care, and ensure the comfort and safety of patients. Surgical nurses also work closely with doctors and other medical team members to coordinate the patient's treatment plan and rehabilitation process. Surgical nurses are also responsible for educating and guiding patients and their families, and helping them understand and cope with the operation process and postoperative care. They also participate in coordinating and implementing quality control and safety measures of surgical nursing to ensure the provision of high-quality nursing services.
