cardioplegia solution
A specialized solution used to arrest the heart during cardiac surgery, containing potassium and other agents to temporarily stop cardiac muscle contraction.
Full Definition
A specialized solution containing high concentrations of potassium, along with other protective agents, used to induce cardiac arrest during open-heart surgery. The solution is delivered directly into the coronary circulation to stop the heart's beating and electrical activity, creating a bloodless, motionless surgical field. Different formulations exist, including crystalloid and blood-based solutions, each designed to provide myocardial protection during the ischemic period of surgery.
Usage
Usage note: Always specify the type (crystalloid, blood-based, warm, cold) when editing surgical reports.
