Comparison of Changes in Thoracic Fluid Content Between On-Pump and Off-Pump CABG by Use of Electrical Cardiometry.

Objectives: To compare the changes in thoracic fluid content, PaO/FO ratio, plateau pressure, compliance, and postoperative ventilation duration in off-pump coronary artery bypass grafting (OPCAB) and on-pump coronary artery bypass grafting (ONCAB).

Design: Prospective observational study.

Setting: Tertiary-care cardiac center.

Balancing a single-ventricle circulation: 'physiology to therapy'.

The parallel supply of the pulmonary and systemic circuits complicates the management of single-ventricle lesions. Achieving a balance between the two limbs of the circulation forms the basis of optimizing the systemic oxygen delivery, with the oxygen availability being highly sensitive to alterations in pulmonary/systemic blood flow ratio ( / ). The identification of a 'balanced' circulation is challenging wherein various parameters should be evaluated in close conjunction with each other.
