title: Effect of unilateral pulmonary artery occlusion on the arterial oxygen pressure of children undergoing pulmonary systemic artery shunt procedures.
abstract: Of 20 children undergoing thoracotomy who had blood-gas analysis at various intervals during their operative procedure, 18 had congenital heart disease causing cyanosis. The venous admixture was apparent on compressing the lung to expose the mediastinal structures and was diminished upon clamping the pulmonary artery to the exposed lung. This observation may be of clinical value in raising the arterial oxygen pressure when sudden deterioration occurs during performance of a systemic pulmonary shunt in cyanotic children.
