Are blood thinners needed after knee surgery?

Hello doctor,

An 80-year-old man underwent a recent septic arthritic joint surgery and was hospitalized for 20 days. The medications prescribed were Levothyroxine 150 mg, Atorvastatin 20 mg, Ramipril 10 mg, Bendroflumethiazide 2.5 mg, Metformin 500 mg twice daily, Tamsulosin 400 mg, and Lansoprazole 15 mg. He was discharged from the hospital with D3 replacement medication.

Doxycycline antibiotics were given for five weeks. A heart murmur and leaky valve were confirmed, but no action was taken. Nothing else was given on the day of discharge. Blood thinner injections were also stopped. My question is, with a person of this age, hypothetically, should the thinners have been continued due to the patient being at higher risk of clotting and heart attack due to the health factors and non-weight bearing for the next coming weeks? Please help.

Thank you.

Hi,

Thank you for the response.

The patient had the right knee joint washout due to sepsis, with no removal. The patient was unaware of the heart condition and was made aware of the condition during hospitalization. That was the stage where he had a heart murmur and a leaky heart valve. During the hospital stay, nothing was done for either of these conditions. Blood-thinning medication was stopped on the day of discharge from the hospital. Due to the heart ischemia and sepsis wash on the right knee, would you still think the patient would need antiplatelet medication and blood thinners also?

Thank you.

Hi doctor,

Thank you for your reply.

He was 70 percent non-weight bearing due to the swelling. With regards to the medication, while in the hospital, I had an electrocardiogram (ECG) and found out from one report that the patient had an enlarged heart of 580 gm with concentric left ventricular hypertrophy and in the posterior wall of the left ventricular also possibly an area of fibrosis. Severe calcified atheromatous narrowing involving the left anterior descending coronary artery. The right main coronary artery is dismayed with mild atheroma. The left circumflex branch is normal. The cardiac valves and atria were normal. The thoracic aorta showed moderate to severe atherosclerosis. For a patient to have this type of heart disease, could it be said hypothetically that they should have been on other medication for a heart condition also?

With this, should they not still have been kept on blood thinners for the duration of time whilst not fully weight-bearing. I greatly appreciate your help on this matter.

Thank you.

Hi,

Thank you for the reply, doctor.

Two months back, my father passed away. What I am trying to establish from these findings of the autopsy report is that there should not have already been signs showing on any scans previously done. Also, if they would already have him on anticoagulants, why would they have stopped it if he is not going to be fully weight-bearing for up to 4 or 5 weeks. Yes, he was 80 years old with a history of high blood pressure, and in the post-mortem report, they say he previously had heart complications, which was incorrect. We were told the first time he passed, he had no heart condition, but then, at the end of the hospitalization, we got the post-mortem report stating he had died from ischemia heart disease.

Would this not have been seen or found over the years from any tests done and have had medication? I am trying to establish if the blood thinners and another heart medication would have made a difference. I want to understand if the anticoagulants or if he had been put on heart medication for his condition would have made any difference to the outcome we had on the first.

Thank you.

Hello doctor,

Thank you for the reply.

So, I will ask a different question as I believe I have made you uncomfortable knowing this is my father. From a medical point of view, if a patient came into you on blood pressure medication, what checks would you do if their blood pressure dropped and became low? Is there a set routine of checks for low blood pressure that would normally be done and the same if the blood pressure is higher than normal? I am just trying to understand things in my mind. How do things work?

Thank you.

Hello doctor,

Thank you for the reply.

As I am not a professional, I do not know what other questions to ask, and I can only go from the information I have from the autopsy. I do not have any other reports from the hospital stay.

Thank you.
