Hypercapnia is a central component of diverse respiratory disorders, while 'permissive hypercapnia' is frequently used in ventilatory strategies for patients with severe respiratory failure. This review will present data from recent studies relating to hypercapnia, focusing on issues that are of importance to anesthesiologists caring for the surgical and/or critically ill patient. ⋯ The mechanisms of action of hypercapnia and acidosis continue to be elucidated, and this knowledge is central to determining the safety and therapeutic utility of hypercapnia in protective lung ventilatory strategies.

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.

ReviewStrategies to reduce blood transfusion: a Latin-American perspective.
Anemia has been demonstrated to be detrimental in several populations such as high-surgical-risk patients, critically ill elderly, and cardiac patients. Red blood cell transfusion is the most commonly prescribed therapy for anemia. Despite being life-saving, it carries a risk that ranges from mild complications to death. The aim of this review is to discuss the risks of anemia and blood transfusion, and to describe recent developments in the strategies to reduce allogeneic blood transfusion. ⋯ An adequate judgment of a clinical condition associated with proper application of the available literature is the cornerstone in the management of transfusion in critical care. Apart from this individualized strategy, the institution of a patient blood management program allows goal-directed approach through preoperative recognition of anemia, surgical efforts to minimize blood loss, and continuous assessment of the coagulation status.
