Either the fluid is persistent leak from the tear which seems somewhat likely. The other possibility is obviously cirrhosis with ascites. As a prior heavy alcohol user, long-term smoker likely some degree of poor lifestyle habits (ie dietary) and his age he has more than enough risk factors to develop cirrhosis.Either way, sampling the fluid will give the necessary info
They are putting a drain in tomorrow morning, so we will find out what thr fluid is then. I feel extremely frustrated right now that there isn't more of a sense of urgency.
