Does any one have any experience with pneumomediastinum? The NICU told me today that my baby boy of 31 5/7 weeks has it. He was born on the 20th with some breathing issues but the X-Rays didn't show anything until today...They were hoping to give him surfactant but now they can't :/. I was hoping if someone give me a little more of information and share their experience with it (if any)... Me and my wifle are so worried. Thank you!
