What common postoperative complication should the nurse monitor after CABG surgery?

Atrial dysrhythmias are a common postoperative complication following coronary artery bypass graft (CABG) surgery. The heart is manipulated during this procedure, which can irritate the myocardial tissue and lead to electrical conduction disturbances. It is particularly notable that atrial fibrillation can occur, especially in the immediate postoperative period. This condition manifests as an irregular and often rapid heart rate, which can increase the risk of stroke and other complications.

Monitoring for atrial dysrhythmias post-CABG is crucial because they can affect hemodynamics and overall patient stability. The incidence of atrial fibrillation following such cardiac procedures can be quite significant, prompting healthcare providers to implement strategies for prevention, such as adequate analgesia, maintaining electrolyte balance, and using beta-blockers if appropriate.

The other conditions listed may also be relevant postoperative concerns, but they are less directly associated with the immediate post-CABG period. For example, dehydration can occur from fluid shifts and third spacing after surgery, and while it is important to monitor for, it is not as prevalent as atrial dysrhythmias in this specific surgical context. Acute respiratory distress syndrome is a serious condition that can arise after various types of surgery but is not as common specifically following CABG. Paral
