<s>[INST] Hi, my 82.5 year old father with a 4- month old pacemaker recently had his gallblatter removed. He was in the hospital for an entire week because he 1) filled up with fluid on his left lung and 2) E. coli was found in his blood. After a week in the hospital he was sent home with a potent antibiotic that is administered via a pic(?). My question....what question(s) should we be asking his infectious doctor and surgical doctors at his one week follow up appointment. Thank you Liz PS. ertapenem IV antibiotic [/INST] Hi. I have read your query. It's not common to fluid filled lung and E.cold infection after gallbladder removal. Your fathers' surgery got complicated, and he got E.cold infection from the hospital. You should ask the following questions from your Doctor.1. Should we get a diagnostic pleural tap? (fluid taken from the lungs for analysis)2. Should we get culture and sensitivity test run on the fluid?3. What is the result of the Blood Culture and Sensitivity test?4. Change the antibiotic according to the sensitivity report?5. Ask about a repeat Chest X-ray to see if the fluid has decreased?6. Can your father be put on oral antibiotics according to the sensitivity of E.cold? These are the questions that your doctor should answer as these tests and their results are very important for the health of your father. </s>
