Understanding the Stages and Symptoms of Pertussis

In this episode, Dr. Rahul Damania, Dr. Pradip Kamat, and Dr. Monica Gray dive into a critical case involving a five-week-old baby facing acute respiratory failure due to pertussis. They chat about how this condition shows up, how it's diagnosed, and the best ways to manage it, especially considering the serious complications it can cause in infants, like pulmonary hypertension and the potential need for ECMO. The conversation underscores the importance of catching it early and providing supportive care, while also highlighting how crucial vaccination is in preventing pertussis. Tune in to learn how severe this disease can be and why staying alert in pediatric care is so important.

Show Highlights:

• Clinical case of a five-week-old infant with acute respiratory failure and pertussis diagnosis
