Anesthesia misdiagnosis, too, will happen! Anesthesiologists are expected to consult the patient’s in a timely manner during surgery, to make accurate judgments, to make timely diagnoses, and not to misdiagnose! Sometimes misdiagnosis by anesthesiologists can cause great harm to patients! For example, myocardial ischemia, myocardial infarction, heart failure, pulmonary edema, pulmonary embolism, and other emergencies can endanger patients’ lives if not diagnosed correctly and in a timely manner. These life-threatening conditions of patients during surgery are handled by anesthesiologists in person, and if handled in a timely manner, patients will be turned to safety; if not handled in a timely manner, or even diagnosed wrongly and delayed emergency, it will bring a serious blow to the life of the patient, or even the death of the patient. The life of the patient during surgery is under the care of the anesthesiologist. As an anesthesiologist, the daily work is closely related to the life of the patient. The anesthesiologist is responsible for the patient’s blood pressure, heart rhythm, respiration, blood internal environment, and sanity, and is the protector of the patient’s life.
