Insertion and Management of Temporary Pacemakers.

Temporary pacemakers are used in a variety of critical care settings. These life-saving devices are reviewed in 2 major categories in this review: first, the insertion and management of epicardial pacemakers after and during cardiac surgery; and second, the insertion of transvenous temporary pacemakers for the emergent treatment of bradyarrhythmias. Temporary epicardial pacemakers are used routinely in patients recovering from cardiac surgery. Borrowing from advances in cardiac resynchronization therapy there are many theoretical and untested benefits to pacing the postoperative cardiac surgery patient. Temporary transvenous pacing is traditionally an emergency procedure to stabilize patients suffering from hemodynamically unstable bradyarrhythmia. We review the traditional and expanding use of transvenous pacemakers inside and outside the operating room.

Con: early extubation in the operating room following cardiac surgery.

Ultra-fast-track anesthesia for cardiac surgery introduces risks to the patient that may be mitigated by transferring the patient to the intensive care unit with a secure airway. These risks include poorly controlled pain leading to catecholamine surges that result in arrhythmias, strain on fresh suture lines, and potentially myocardial ischemia. On the converse side, the patients frequently require titration of potent narcotic pain medicine that can lead to hypoxemia and hypercarbia in the immediate postoperative stage causing myocardial dysfunction. Finally, the economic benefit of ultra-fast-track anesthesia is questionable and until there is a complete cost analysis that includes operating room time, cost of ultra-fast-track medications, and compares the cost of reintubation and delayed surgical operation, it is difficult to weigh in on the cost benefit advocated in the literature.
