Abstract: This mentions a 47-year-old male patient who presented with cardiac discomfort, numbness and pain in the extremities after touching high-voltage electricity, and also presented with burns on the hands and wrists for consultation. Through physical examination as well as ancillary examinations, the patient was diagnosed with electrical shock injury secondary to myocardial injury, peripheral nerve injury, and The patient was diagnosed with myocardial injury, peripheral nerve injury, and soft tissue skin injury secondary to electric shock. The patient was given medication and debridement treatment. After 1 week of treatment, the patient’s condition was controlled and all abnormal indicators returned to normal. The patient’s condition was controlled after 1 week of treatment, and all abnormal indicators were normalized. The patient was inadvertently electrocuted (380 volts) while operating a machine 2 hours before the initial consultation, and had a loss of consciousness and one convulsion lasting about 2 minutes. He regained consciousness on his own and woke up with chest tightness, chest pain, shortness of breath and weakness, accompanied by pain and numbness in the right hand and both lower limbs. On examination, the patient was found to have a ruptured and scabbed right hand and left wrist. The initial diagnosis was electric shock injury and soft tissue injury to the hand and wrist. After admission, CT examination of the head was performed, which showed no abnormality; ECG examination showed ST-segment shift in leads V1-V5 and T-wave inversion; routine blood tests showed leukocytes 17.8*10^9/L, neutrophil percentage 88.2%, troponin 4.065ug/L, creatine kinase 1160U/L, creatine kinase isoenzyme 39.3U/L, lactate dehydrogenase 252U/L. The patient was also considered to have myocardial injury. II. Treatment After considering that the patient had cardiac symptoms, he was immediately given ECG monitoring. He communicated with the patient that it takes at least 48 hours to monitor ECG, mainly for timely detection of late arrhythmogenic lesions after electrocution, and informed the patient that cardiac symptoms such as chest tightness and chest pain were caused by myocardial injury, and suggested resting as flat as possible and reducing the amount of activity. Ask the trauma surgeon to give the wrist debridement and timely injection of tetanus antitoxin serum, which is due to the wound of electric shock injury is often deep and easy to secondary anaerobic bacterial infection, short-term intravenous use of amoxicillin to prevent infection, and intravenous administration of fructose, adenosine triphosphate and other drugs to nourish the myocardium and improve the energy metabolism of cardiomyocytes, B vitamins to nourish the nerves, glutathione to protect the liver and kidneys and other multi-organ therapy. The electrocardiogram and myocardial enzyme profile were dynamically rechecked every 1-2 days, and it was found that the electrocardiogram gradually returned to normal and the creatine kinase level gradually decreased. After these treatment measures, the patient’s symptoms such as chest tightness, chest pain, shortness of breath, and weakness of the body were significantly relieved, and the symptoms of peripheral nerve injury such as numbness and pain of both lower limbs gradually disappeared, and no new symptoms of discomfort appeared. On the 7th day of hospitalization, the rechecked ECG was normal, creatine kinase 57 U/L, lactate dehydrogenase 225 U/L, creatine kinase isoenzyme 0.8ug/L, and troponin 0.053ug/L. All these abnormal laboratory results returned to normal levels. The hand and wrist wounds were well repaired and no secondary infection occurred. The patient was advised to be discharged from the hospital and was instructed to visit the outpatient surgery for regular medication changes. IV. Precautions We are very glad that this patient’s condition was significantly controlled and discharged successfully. The patient was advised to take more rest and avoid overexertion after discharge. The patient was informed that no adverse sequelae would be left behind, so as to alleviate the patient’s concern about the disease and relieve his nervousness. Considering that the patient’s hand wound had not healed, it was suggested that regular outpatient surgical dressing changes would be sufficient, and the patient was advised that tissue damage caused by electrical burns usually takes a long time to repair, so he should be psychologically prepared. In daily life, we should pay attention to personal protection and take safety measures to prevent the recurrence of electrocution. V. Personal insight Through this case tells us that if you are in contact with high-voltage equipment at work, safety measures must be in place to take responsibility for your own safety and avoid irreversible consequences. And once electrocution occurs, we must immediately send to the hospital for first aid to avoid irreversible damage, as in the case of the patient in a timely manner, the prognosis of the sequelae of electrocution is better. And most of the daily life of electrocution can be avoided, which requires everyone to master the common sense of safety electricity, the home often use electrical appliances and lines need to ask professional electricians to regularly check and repair; wipe the shell of electrical equipment, wires or plugs with wet hands or wet cloth is strictly prohibited to prevent short circuits, aging leakage of electric shock accidents; if you need to move electrical equipment, you must first cut off the power supply to prevent electrocution.
