IBCC Episode 53 - Submassive & Massive Pulmonary Embolism | The Internet Book of Critical Care Podcast

This podcast episode features a detailed discussion between Josh Farkas and Adam Thomas about the complexities of managing submassive and massive pulmonary embolisms (PE). They delve into risk stratification, emphasizing the importance of echocardiography and considering factors beyond clot burden. The conversation covers initial resuscitation strategies, including lab bundles and vital sign interpretation, highlighting the significance of bradycardia as a worrisome sign. They explore various treatment options, such as anticoagulation, thrombolysis, and advanced interventions like surgical embolectomy and ECMO, while also addressing unusual and confusing clinical scenarios related to PE management, including a critical review of the PECH score and the controversial PESI score. The hosts share their opinions on the optimal use of TPA, vasopressors, and pulmonary vasodilators, and stress the importance of avoiding unnecessary procedures like intubation and arterial lines.
