What this trial studies

This study evaluates the effectiveness of a single high dose of dexamethasone (1 mg/kg) in reducing the incidence of post-operative acute kidney injury in patients undergoing elective cardiac surgeries that require cardiopulmonary bypass. Participants will be randomly assigned to receive either dexamethasone or a placebo (normal saline) during their surgery. Comprehensive preoperative assessments will be conducted to ensure patient safety and eligibility. The study aims to determine if dexamethasone can significantly lower the risk of kidney complications following surgery.

Who should consider this trial

Good fit: Ideal candidates are adults aged 30-65 scheduled for elective cardiac surgery requiring cardiopulmonary bypass with an ASA score of III-IV.

Not a fit: Patients with a history of acute kidney injury, diabetes, or those undergoing urgent or off-pump surgeries may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the occurrence of acute kidney injury in patients undergoing cardiac surgery, improving recovery outcomes.

How similar studies have performed: While the use of dexamethasone in this context is being explored, similar studies have shown promise in reducing complications, making this approach both relevant and potentially impactful.
