I just wanted to ask what are the possible signs of aspiration pneumonia? We had a patient, a 30 weeker expired recently. The neonatologist says it might be aspiration pneumonia. That night, breast milk feedings via OGT of 4ml every 2hrs was given, and the last feeding was 2 hours prior to code. Tachycardic, no retractions, but with primary apnea, desats frequent. No oxygen was given. She was never intubated.Before endorsement for the next shift, the neonate vomitted suddenly, yellowish and with milk particles, then turned into blue hence a code was called. It was all so sudden, in 2 hours she was pronunced dead. She was pinkish the entire shift, not until he vomitted all over. The neonatologist says it is very impossible that the patient will vommit because we are only feeding her 4ml. However, there were reports of vomitting prior to these event when she was fed with 1ml.Thank you for your responses.
