Open cardiac surgery may cause severe postoperative pain and the activation of a perioperative stress response. If not treated adequately, the patient may suffer increased morbidity, a longer hospital stay, and higher overall costs. This article reviews the literature regarding various modalities for management of postoperative pain after cardiac surgery. ⋯ Although published data remain limited, recent evidence indicates that patients may benefit from the addition of a variety of novel pain-management strategies currently under investigation. Selection of a multimodal approach to perioperative pain management is advocated, including selective application of regional analgesia, non-narcotic medications, and complimentary alternative options to improve patient comfort and overall outcome.

Chest tube protocols are still largely dictated by personal preferences and experience. A general lack of published evidence encourages individual decision-making and hinders the development of clear-cut guidelines. The aim of this review is to establish standardized procedures with recommendations for size and number of inserted tubes, ideal suction levels and duration of thoracostomy. ⋯ Thoracic procedures are heterogeneous and postsurgical requirements vary in accordance. Most resections will not require more than one large bore (≥20F) catheter and will benefit from postoperative active suction. Even though only moderate-quality evidence suggests that suction reduces incidence of pneumothorax if compared to water seal and its effects on prolonged air leak are controversial, recent studies encourage application of active suction. Removal of chest tubes appears to be well tolerated even with a secretion of above 450 ml/day.

ReviewProtection strategies during cardiopulmonary bypass: ventilation, anesthetics and oxygen.
To provide an update of research findings regarding the protection strategies utilized for patients undergoing cardiopulmonary bypass (CPB), including perioperative ventilatory strategies, different anesthetic regimens, and inspiratory oxygen fraction. The article will review and comment on some of the most important findings in this field to provide a global view of strategies that may improve patient outcomes by reducing inflammation. ⋯ Lung-protective mechanical ventilation, inhalation anesthesia, and high FiO(2) have the potential to reduce postoperative complications in patients undergoing CPB; however, larger, well powered, randomized control trials are still needed.
