In clinical routine work, there are often some famous clinical experts in the diagnosis of patients, using some seemingly absurd, but in fact very effective non-standard examination methods, such as blowing, ask a question, press, smell, touch, look, these methods actually reflect a deep understanding of the patient’s pathophysiology, worthy of reference, is described below. I. Blowing into the eye to diagnose hysteria Hysteria is a psychological disorder often encountered by emergency physicians, when the patient is suspected of hysteria, the doctor can blow into the patient’s eye, such as the patient has blinking action, often suggesting that the patient is suffering from hysteria, which is a manifestation of the patient’s avoidance action. Second, questioning to diagnose asthma Asthma patients, due to bronchospasm, the most important manifestation is expiratory dyspnea, and human vocalization is through the airflow of exhalation, impact on the vocal organs, vibration vocalization; so asthma patients occur more difficulties, manifested as a change in volume and tone. In emergency clinical work, if patients have difficulty answering, they need to pay attention to asthma in addition to laryngeal lesions. Third, the palm impression on the chest to diagnose shock Capillary and microcirculatory disorders are important manifestations of shock, evaluation of capillary microcirculatory status is a problem that emergency clinicians often need to solve: at this time, you can use the palm of your hand to press in the patient’s forehead, observe the palm impression fading, which mainly reflects the reperfusion process of capillaries. If the palm imprint fades very slowly, which often suggests that the patient has capillary circulation disorders, is one of the manifestations of poor microcirculation in shock. Fourth, the smell of blood to diagnose upper gastrointestinal bleeding upper gastrointestinal bleeding, such as the stomach is full of fresh blood, can be smelled when breathing blood. At this time, the doctor can be close to the patient’s face, such as smelling fishy gas, often suggests fresh bleeding. V. Diagnosis of pleural effusion by touching the thorax When the patient has pleural effusion, the fluid can be pushed outward against the thorax, and a cut can be produced in the outer thorax equivalent to the plane of pleural effusion. Below the plane of fluid accumulation, the thorax is outward, and above the plane of fluid accumulation, the thorax is inward; at this time, when the thorax is touched from above and below, changes in the shape of the thorax can be felt in the plane of fluid accumulation in the thorax. This method can also be used to determine the extent of the left side of the cardiac border.
