The present review evaluates the evidence available in the literature tracking perioperative mortality and morbidity as well as the pathogenesis and management of acute lung injury (ALI) in patients undergoing thoracotomy. ⋯ Knowledge of the perioperative risk factors of major complications and understanding of the mechanisms of postthoracotomy ALI enable anesthesiologists to implement 'protective' lung strategies including the use of low tidal volume (VT) with recruitment maneuvers, a goal-directed fluid approach and prophylactic treatment with inhaled beta2-adrenergic agonists.

ReviewPostoperative care after pulmonary resection: postanesthesia care unit versus intensive care unit.
In an effort to maximize resource utilization and contain costs, immediate postoperative care after noncardiac thoracic surgery is often done in either the postanesthesia care unit or dedicated step down units, leaving the ICU for complex surgical cases, overtly high-risk patients, or the treatment of severe postoperative complications. This review analyzes the current modalities affecting length of stay and costs, mainly by allocating patients after elective lung resection to different postoperative areas according to their needs. ⋯ The development of models to help predict elective ICU admission should facilitate optimal care, cutting costs and shortening length of stay after lung resection.

ReviewUpdate on the role of paravertebral blocks for thoracic surgery: are they worth it?
To consider optimal analgesic strategies for thoracic surgical patients. ⋯ There is good evidence that paravertebral block can provide acceptable pain relief compared with thoracic epidural analgesia for thoracotomy. Important side-effects such as hypotension, urinary retention, nausea, and vomiting appear to be less frequent with paravertebral block than with thoracic epidural analgesia. Paravertebral block is associated with better pulmonary function and fewer pulmonary complications than thoracic epidural analgesia. Importantly, contraindications to thoracic epidural analgesia do not preclude paravertebral block, which can also be safely performed in anesthetized patients without an apparent increased risk of neurological injury. The place of paravertebral block in video-assisted thoracoscopic surgery is less clear.

ReviewUpdate on one-lung ventilation: the use of continuous positive airway pressure ventilation and positive end-expiratory pressure ventilation--clinical application.
The purpose of this review is to examine the evidence for and the clinical use of continuous positive airway pressure (CPAP) and positive end-expiratory pressure (PEEP) for the management of one-lung ventilation during thoracic surgery. CPAP and PEEP use are important as we are increasingly challenged with patients with less respiratory reserve and greater comorbidity leading to the need for greater clinical management and more interventions during one-lung ventilation for thoracic surgery to prevent perioperative complications. ⋯ CPAP and PEEP are useful not only to treat hypoxia and atelectasis as the consequence of one-lung ventilation, perhaps more importantly, also as part of a protective lung-ventilation strategy to ameliorate mechanical stress and prevent acute lung injury.

ReviewOpen or minimally invasive esophagectomy: are the outcomes different?
Since the beginning of the 1990s, the use of minimally invasive esophagectomy instead of the open technique has increased. Should this type of approach change the way we manage anesthesia for a patient undergoing esophagectomy for cancer? ⋯ The implantation of minimally invasive esophagectomy seems inevitable in spite of the absence of randomized, controlled trials. The use of the prone position with one lung ventilation during minimally invasive esophagectomy seems positive. Protective ventilation during one lung ventilation may help to prevent pulmonary complications. Finally, the well accepted use of thoracic epidural anesthesia now has a new positive role following esophagectomy, improving the perfusion at the anastomotic level.
