Obstructive shock is a form of shock due to physical obstruction of the filling or emptying of the heart.[2] This results in not enough blood flow to body tissues.[3] Symptoms may include confusion, cool arms and legs, fast heart rate and weak pulses.[2] Onset is generally very rapid.[3] Complications may include multiple organ dysfunction syndrome.[2]
Causes include pulmonary embolism, cardiac tamponade, tension pneumothorax, and atrial tumors.[1][2] Obstructive shock presents similar to and is sometimes grouped together with cardiogenic shock.[2][4][3] Diagnosis is generally based on symptoms and examination.[2] However, multiple forms of shock may present together.[3]
Treatment depends on the underlying cause.[2] Cardiac tamponade may be treated with pericardiocentesis; tension pneumothorax with needle decompression or chest tube; and pulmonary embolism with thrombolysis and anticoagulation, or a surgical embolectomy.[2] Obstructive shock makes up less than 2% of cases of shock in the intensive care unit.[5][3]
