I'm really worried about my dad. He's 70 and went through a pretty tough time with his aorta bursting back in January. The doctors did Bentall Surgery, and it seemed like things were getting better, but then he got a mild case of COVID on February 4th. They've been treating him for that and a bit of fluid in his left lung with antibiotics, and there have been improvements according to his chest X-rays. The problem is, he's been having a low-grade fever in the evenings, around 99-100 degrees, since the surgery. It's been more than a month now with this persistent fever. Do you think this is just a post-op thing or maybe related to COVID? I just really need to understand what's going on. It's pretty concerning for us.

In this case, the persistent low-grade fever in the evening could be due to various factors, including post-operative recovery, underlying infection, or inflammatory response. Since your father recently underwent Bentall Surgery and is also recovering from mild COVID-19 infection, it is essential to monitor his symptoms closely. To address the fever, the doctors may consider prescribing antipyretic medications such as Acetaminophen (Tylenol) at a dose of 650mg to 1000mg every 4-6 hours as needed to help reduce the fever and provide comfort. Additionally, if there are signs of ongoing infection, antibiotics such as Amoxicillin-Clavulanate (Augmentin) at an appropriate dose may be considered based on the specific infection and sensitivity. It is crucial to continue following up with the medical team to assess the underlying cause of the fever, monitor his overall condition, and adjust the treatment plan accordingly. Regular communication with the healthcare providers will help in managing his recovery effectively.
