Early extubation after complex neonatal surgery should be the result of excellent surgery and comprehensive perioperative care.
See Article page 1591.
Early extubation in congenital cardiac surgery reduces the complications associated with prolonged intubation, avoiding the consequences of sedation and the effects of positive-pressure ventilation.

Early extubation has a greater success rate in children with greater body weights and those undergoing shorter surgical procedures.2
Delayed extubation is considered an indicator of poor outcomes in most quality control programs. In the Society of Thoracic Surgeons database, early extubation after Fontan operation or repairing tetralogy of Fallot is mostly discussed.3
In this issue of the Journal, Varghese and colleagues

are the first to publish outcomes of immediate extubation (IE; n = 5) in the operating room (OR) after Norwood stage 1 palliation (S1P) with satisfactory clinical outcomes.Few studies have found a difference between IE in the OR and early extubation in the intensive care unit. We posit that these 2 treatments should have the same clinical results. Furthermore, extubation in the OR carries an additional risk of airway uncertainty during patient transportation. The benefits of IE after Norwood S1P are hard to determine from the work of Varghese and colleagues because of the small patient groups in their study. However, successful IE after Norwood S1P in this case series is a benchmark of success in the field of complex neonatal cardiac surgery, especially because Norwood S1P is the greatest-risk category in the congenital heart surgery database.
The prerequisite of successful IE is perfect anatomical repair and minimal intraoperative insult. Varghese and colleagues chose to use a right ventricle-to-pulmonary artery shunt rather than a Blalock–Taussig shunt, which might have more stable hemodynamic status immediately after surgery.

In addition, they chose a dual arterial cannulation technique to achieve continuous mild hypothermia bypass. Avoiding deep hypothermic circulatory arrest may decrease hemodynamic instability and end-organ ischemia–reperfusion injury; the benefits of the warm bypass strategy in Norwood S1P warrant further study using a larger patient series.The anesthetic management included preoperative adjustment of a patient's medication and volume status, judicious use of anesthetic medications intraoperatively, hemodynamic and hemostatic management, normothermia, and well-planned postoperative analgesia and sedation. These factors are crucial for achieving IE in patients after congenital heart surgery.
Despite the success of early extubation, the length of stay was still jeopardized by arrhythmia, low-output syndrome, chylothorax, vocal cord palsy, and feeding problems. Furthermore, extubation failure is associated with increased mortality in the literature.

We deem early extubation to be a surrogate for fast physiological recovery. Fast recovery, including removal of the endotracheal tube, sedation, and inotropic agents, requires a perfect anatomical repair, minimal physiological disarrangement, and optimal anesthetic management to simplify postoperative care and facilitate enhanced recovery. Enhanced recovery for patients and the improved long-term outcome, not solely faster extubation, should be the primary goal in congenital cardiac surgery.
