Initial treatment given will usually be supportive in nature, for example administration of oxygen, and monitoring. There is little care that can be provided pre-hospital other than general treatment for shock. Some teams have performed an emergency thoracotomy to release clotting in the pericardium caused by a penetrating chest injury.
In cardiac tamponade, blood or other fluids building up in the pericardium can put pressure on the heart so that it is not able to beat. This condition can be recognized by the presence of a narrowing pulse pressure , muffled heart sounds , distended neck veins, electrical alternans on the electrocardiogram , or by visualization on echocardiogram .
A resuscitative thoracotomy is indicated when severe injuries within the thoracic cavity (such as hemorrhage) prevent the physiologic functions needed to sustain life.The injury may also affect a specific organ such as the heart, which can develop an air embolism or a cardiac tamponade (which prevents the heart from beating properly).
Patient with cardiac tamponade following penetrating trauma may be good candidates for thoracotomy: Hypoxia Increase oxygen content of the blood Treatment of hypoxia is aimed at maintaining the patient's airway and controlling breathing. Initial treatment may include bag-valve mask, nasopharyngeal airway, oropharyngeal airway, or other airway ...
After these stabilizing measures, further treatment depends on the cause. Treatment of the underlying condition can quickly resolve the shock. For tension pneumothorax, needle decompression should be done immediately. A chest tube is also inserted. [3] [8] Cardiac tamponade is treated through needle or surgical decompression. [3]
A very large hemorrhagic pericardial effusion due to malignancy as seen on ultrasound which was causing tamponade. closed arrow: the heart, open arrow: the effusion. Tamponade (/ ˌ t æ m. p ə ˈ n eɪ d / [1]) is the closure or blockage (as of a wound or body cavity) by or as if by a tampon, especially to stop bleeding. [2]
This compression, called cardiac tamponade, is often associated with hemopericardium and can be fatal if not diagnosed and treated promptly. [6] Early signs of this compression include right atrial inversion during ventricular systole followed by diastolic compression of the right ventricular outflow tract .
Pericardiocentesis can be used to diagnose and treat cardiac tamponade. [3] [4] Cardiac tamponade is a medical emergency in which excessive accumulation of fluid within the pericardium (pericardial effusion) creates increased pressure. [5] This prevents the heart from filling normally with blood.
