A Case of Pertussis in the PICU
PICU Doc On Call
Complications of Pertussis in Infants
This chapter outlines the serious complications of pertussis in infants under two months, particularly emphasizing the heightened risks for unimmunized babies. It discusses diagnostic approaches and management strategies, including the necessity of maternal vaccination and the use of advanced interventions. The importance of early identification and support in preventing severe morbidity and mortality in affected infants is highlighted.
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.
