Seminars in cardiothoracic and vascular anesthesia

Delirium was described by Hippocrates over 2500 years ago and it remains an important clinical problem today. Work continues to improve definition, prevention, diagnosis, and treatment, but relatively young science remains. Delirium affects 12,500,000 patients and costs $152,000,000,000 every year. ⋯ The contribution of delirium to cognitive decline remains controversial and concerning. As dollars shrink and cost does not, delirium becomes increasingly important. In an aging population of increasing frailty, delirium will contribute increasingly to long-term morbidity and even mortality.

Case ReportsOne-lung ventilation for surgical repair of thoracic aortic aneurysm.
Advances in the surgical approach to thoracic aortic aneurysm repairs have led to the increasing use of one-lung ventilation. Today's practice of cardiothoracic and vascular anesthesia requires a clear understanding of the techniques available for lung separation and the technical skills necessary to employ them. In this article, we discuss and evaluate the options for one-lung ventilation in thoracic aortic aneurysm repair with regard to preoperative, intraoperative, and postoperative management.

Vascular surgical patients are a diverse group of patients who tend to be elderly, with multiple comorbidities, while vascular procedures may involve significant blood loss and ischemia of tissues beyond the arterial obstruction. Regional anesthesia techniques may offer benefits to patients undergoing vascular surgery because of their cardiorespiratory comorbidities. However, this group of patients is commonly receiving multiple medications, including anticoagulants, so regional techniques are not without risks. This review will discuss this topic based around 3 fundamental revascularization procedures, carotid, abdominal aortic aneurysm repair, and infrainguinal surgery, discussing the clinical applications of regional techniques relevant to each key area.

Case ReportsTreatment of acute silicoproteinosis by whole-lung lavage.
Acute silicoproteinosis is a rare disease that occurs following a heavy inhalational exposure to silica dusts. Clinically, it resembles pulmonary alveolar proteinosis (PAP); silica exposure is thought to be a cause of secondary PAP. ⋯ Without clinical improvement despite antibiotic and steroid treatment, the patient was scheduled for whole-lung lavage under general anesthesia. Anesthetic challenges included double-lumen tube placement and single-lung ventilation in a hypoxic patient, facilitating lung lavage, and protecting the contralateral lung from catastrophic spillage.

The impact of dexmedetomidine infusion in sparing morphine consumption in off-pump coronary artery bypass grafting.
Recovery from off-pump coronary artery bypass (OPCAB) has been reported to be more advantageous than conventional coronary artery bypass grafting with regard to both hospital and intensive care unit length of stay. Dexmedetomidine is a selective α-2 agonist that has been used successfully as an adjunct to narcotics in adult and pediatric cardiac surgery. The aim of this study was to assess the effect of dexmedetomidine on the recovery, total narcotic consumption, and total hospital and intensive care unit length of stay in patients undergoing OPCAB. ⋯ Our study showed that dexmedetomidine might be an effective adjuvant in reducing both total hospital and intensive care unit length of stay in patients undergoing OPCAB. Dexmedetomidine might play a role in reducing total morphine and fentanyl consumption in OPCAB.
