Clinical symptoms of patients with pericardial effusion include dyspnea, hoarseness, dysphagia, abdominal pain, etc. Pericardiocentesis drainage is the first choice for treatment, and anti-shock treatment is also needed. 1. Symptoms: dyspnea, hoarseness, dysphagia, abdominal pain, edema, pleural effusion, shock, etc. Infectious pericarditis can be accompanied by fever. 2.Treatment: (1) Pericardiocentesis and drainage: the specific operation is: firstly, determine the location of pericardial effusion through cardiac ultrasound equipment, then disinfect the puncture site, inject local anesthetic and perform pericardiocentesis. Pericardiocentesis can quickly relieve the cardiac compression obstruction, and at the same time, it can also carry out relevant examination of pericardial effusion to clarify the etiology. (2) Anti-shock treatment: If the patient has already suffered shock and needs to replenish blood volume, whole blood and balanced fluids can be transfused for volume expansion treatment, and vasoactive drugs, such as norepinephrine and dopamine, can be used at the same time. When pericardial effusion is found, consult the doctor in time and actively cooperate with the doctor’s treatment.
