Anesthetic considerations during caval inflow occlusion in children with congenital heart disease.
Caval inflow occlusion (IO) was introduced to facilitate surgical pulmonary and aortic valvotomy without cardiopulmonary bypass (CPB). Although a technique that is used infrequently today, it remains useful in some patients with complex single-ventricle congenital cardiac defects who require an atrial septectomy. The potential for complications and anesthetic considerations have not been described previously. ⋯ IO is an effective technique for short intracardiac procedures without the need for CPB. Close collaboration between anesthesia and surgical staff is essential to keep the duration of IO as short as possible and because of the potential for hemodynamic instability.

Deep hypothermic circulatory arrest and the femoral-to-radial arterial pressure gradient.
To determine the femoral-to-radial arterial pressure gradient, as well as the factors associated with them, in patients receiving cardiopulmonary bypass (CPB) with profound hypothermia and circulatory arrest. ⋯ The femoral-to-radial arterial pressure gradients, particularly systolic, after CPB, were greater and of longer duration in these patients undergoing deep hypothermic circulatory arrest than gradients previously reported for routine CPB. Central arterial pressure monitoring is recommended for patients undergoing deep hypothermic circulatory arrest, being valuable both for intraoperative and postoperative care.
