Airway management is unequivocally the most important responsibility of the emergency physician. No matter how prepared for the task, no matter what technologies are utilized, there will be cases that are difficult. ⋯ When the patient is encountered, it is too late to check whether appropriate equipment is available, whether a rescue plan has been in place, and what alternative strategies are available for an immediate response. The following article will review the principles of airway management with an emphasis upon preparation, strategies for preventing or avoiding difficulties, and recommended technical details that hopefully will encourage the reader to be more prepared and technically skillful in practice.

Pneumonia is an important cause of mortality in intensive care units. The incidence of pneumonia in such patients ranges between 7 and 40%, and the crude mortality from ventilator associated pneumonia may exceed 50%. Although not all deaths in patients with this form of pneumonia are directly attributable to pneumonia, it has been shown to contribute to mortality in intensive care units independently of other factors that are also strongly associated with such deaths. ⋯ A combination of topical and systemic prophylactic antibiotics reduces respiratory tract infections and overall mortality in adult patients receiving intensive care. A treatment based on the use of topical prophylaxis alone reduces respiratory infections, but not mortality. The risk of occurrence of resistance as a negative consequence of antibiotic use was appropriately explored only in the most recent trial by de Jonge, which did not show any such effect.

Review Comparative Study
The management of patients who require temporary reversal of vitamin K antagonists for surgery: a practical guide for clinicians.
The management of patients who require temporary interruption of vitamin K antagonists is a common clinical problem, affecting an estimated 400 000 patients per year in Europe and North America. Managing such patients is challenging because of the lack of randomized trials assessing different perioperative anticoagulation management strategies and inconsistent recommendations from consensus groups. Recent non-randomized trials have helped to estimate the risks for arterial thromboembolism and bleeding with bridging anticoagulation involving low-molecular-weight heparin. The objectives of this review are to describe bridging anticoagulation and how it may be used with a short-acting heparin, such as unfractionated heparin or low-molecular-weight heparin, to discuss preoperative patient management, focusing on risk stratification for thromboembolic events and interruption of vitamin K antagonist therapy, and to discuss postoperative patient management, focusing on surgery-related bleeding risk and the resumption of bridging anticoagulation and vitamin K antagonist therapy.
