The goal of the preoperative evaluation for thoracic surgery is to assess and implement measures to decrease perioperative complications and prepare high-risk patients for surgery. Major respiratory complications, such as atelectasis, pneumonia, and respiratory failure, occur in 15% to 20% of patients and account for most of the 3% to 4% mortality rate. Development of pulmonary complications has been associated with higher postoperative mortality rates. ⋯ In addition, there is a growing tendency to offer surgery to patients with significant lung function impairment; hence a higher incidence of intraoperative gas-exchange abnormalities can be expected. The anesthesiologist must also consider the risks of denying or postponing a potentially curative operation in patients with lung cancer. Detailed consideration of the information provided by preoperative testing is essential to successful outcomes following thoracic surgery.

ReviewAnesthetic management of patients with pulmonary hypertension.
Advances in the treatment of patients with chronic pulmonary hypertension have greatly improved their functional status and longevity, and increasing numbers of these complex patients are presenting for elective noncardiac surgery. In this communication we will briefly review the classification and pathophysiology of pulmonary hypertension, summarize outpatient pharmacotherapy approaches, and discuss the perioperative preparation and management of these complex patients. With an understanding of the underlying pathophysiology of the disease and pharmacology of these new therapies, combined with careful perioperative planning and care, these patients can safely undergo elective surgical procedures.

ReviewAnesthetic considerations for lung transplantation.
Lung transplantation is the definitive treatment for end-stage lung disease. The number of lung transplantations performed is limited by the number of donors available and is far outnumbered by the potential recipients on the waiting list. ⋯ Specific anesthetic concerns are associated with lung transplantation, including careful preoperative assessment of pulmonary and cardiac function, adequate venous access and monitors, and ventilation techniques, such as 1-lung ventilation and lung-protective strategies to decrease the risks of reperfusion injury, barotrauma, and re-expansion pulmonary edema. Intraoperative transesophageal echocardiography, cardiopulmonary bypass, and inhaled nitric oxide can also be important tools for the anesthesiologist to optimize patient care during this challenging procedure.

ReviewAppropriate ventilatory settings for thoracic surgery: intraoperative and postoperative.
Mechanical ventilation of patients undergoing thoracic surgery is often challenging. These patients frequently have significant underlying comorbidities, including cardiopulmonary disease, and often must undergo 1-lung ventilation. Perioperative respiratory complications are common and are multifactorial in etiology. ⋯ Gas exchange to provide acceptable end-organ oxygenation remains a primary goal but so too is minimization of risks for acute lung injury. Every ventilator strategy is associated with potential beneficial and adverse side effects. Understanding the impact of various ventilation strategies allows clinicians to provide optimal care for patients.

Development and implementation of a pediatric cardiac anesthesia/intensive care database.
Systematic collection and electronic storage of data can assist in improving quality and efficiency of patient care and can provide a data set to interrogate for subsequent performance improvement and clinical research purposes. In this article, an electronic perioperative pediatric cardiac surgery database to be used by a multidisciplinary care team was designed, developed, and implemented. ⋯ Implementation of the described database has proved to be invaluable for quality assurance and statistical analysis of data relevant to patient care. From the overall positive experience, it was concluded that the electronic data management does not always need major cost investment.
