A Patient with AMS from a Nursing Home
An elderly patient is transferred from an outlying nursing home for altered mental status. No report is given to the paramedics other then he is “not acting normally”. He has a history of HTN, DM, and a hospitalization about 2 months PTA for a fall resulting in multiple rib fractures and a hip fracture that required ORIF.
Prior to ED arrival, EMS calls informing you he has had 2 episodes of bradycardia into the 40s (resolved), a BPS in the 70s (getting LR) and that his code status is unknown. On arrival, the patient has a heart rate in the 70s, a MAP of 55, and is altered. As the patient is being worked up and resuscitated, you perform a bedside RUSH exam and note the following image showing an obvious pericardial effusion.
How can you tell if it is causing tamponade or if the patient has another etiology like a pulmonary embolus?
The patient does have tamponade as evidenced by systolic collapse of the right atrium and diastolic collapse of the right ventricle. The IVC was plethoric and not affected by respirations. 400cc of hemorrhagic effusion was removed with return to baseline mental status and an improvement in the patient’s blood pressure to 110/70.
