As an international Certified Registered Nurse Anesthetist (CRNA), your main duties are to administer anesthesia in overseas health care settings, in addition to fulfilling general nursing responsibilities. Many CRNAs work as part of international healthcare organizations, or through international staffing agencies that help provide coverage to hospitals in remote areas or to those with staff shortages. You are an integral part of any surgical procedure requiring anesthesia. You perform preoperative duties, such as preparing the patients for the OR, administering preoperative medications, and taking vital signs. During surgery, you monitor the patient's anesthesia and communicate closely with the surgeon. Your post-operative responsibilities are to educate your patient about home care and to look for any side effects related to anesthesia.
