Hydrocortisone is a steroid medication that helps reduce inflammation and suppress immune system responses in the body. It’s commonly used during and after surgery to help manage stress and inflammation. This medication is a synthetic version of cortisol, a natural hormone produced by your body.

Fludrocortisone is another type of steroid medication that helps regulate salt and fluid levels in the body. It works by helping your body retain sodium and excrete potassium. This medication is particularly useful in maintaining stable blood pressure and proper fluid balance during and after surgical procedures.

These medications are being studied in combination as a prolonged therapy for patients undergoing planned heart surgery, to see if they can improve outcomes compared to patients who don’t receive this treatment.

Acute Renal Failure – A condition where the kidneys suddenly stop working properly, leading to a build-up of waste products in the blood. It develops over a few hours or days, causing fluid retention and changes in blood chemistry. The condition can affect the body’s ability to maintain proper fluid balance and regulate important minerals like sodium and potassium. Common signs include decreased urine output, swelling in legs and ankles, and shortness of breath.

Postoperative Pulmonary Complications – A group of breathing problems that can occur after surgery. These complications can include difficulty breathing, decreased oxygen levels, and accumulation of fluid in the lungs. The condition typically develops within the first few days after surgery and can affect normal breathing patterns.

Stroke – A sudden interruption of blood flow to part of the brain, causing neurological symptoms. It occurs when either a blood vessel becomes blocked or bursts, leading to damage in brain tissue. The condition causes sudden onset of symptoms such as weakness on one side of the body, difficulty speaking, or vision problems. Brain imaging typically shows the affected area of the brain.

Mediastinitis – An inflammation or infection of the tissue in the middle of the chest between the lungs. This condition can develop after chest surgery and affects the area that contains the heart, large blood vessels, windpipe, and other important structures. The infection can cause chest pain, fever, and general discomfort.

Hypernatremia – A condition where there is too much sodium in the blood. It occurs when the body’s water and sodium balance is disrupted, leading to sodium levels above normal range. This imbalance can affect how the body’s cells function and regulate fluids.

Hyperglycemia – A condition where blood sugar levels become too high. It occurs when the body cannot effectively use or produce insulin to regulate blood glucose. The condition can develop gradually and may require insulin therapy to maintain proper blood sugar levels.
