An increasing number of elderly patients are admitted to the hospital for critical diseases and the gap between supply and demand of intensive care resources is a growing problem. To meet this challenge, 4 beds in a 24-bed acute care for the elderly (ACE) medical unit were dedicated to a subintensive care unit (SICU). Severely ill elderly medical patients, requiring a higher level of care than provided in ordinary wards, are admitted. The aim of the study was to describe the characteristics of the setting and to discuss its usefulness based on data obtained after the first period of implementation. ⋯ The SICU is an innovative method to treat frail elderly patients with more severe conditions. Low hospital mortality compared with that of severe patients in the ACE unit supports the usefulness of this model. It could be implemented in medical units of large hospitals in order to give optimal care and advanced interventions to the frail elderly and to avoid intensive care unit overcrowding.

We believe that clinical ethics consultation (CEC) has as its goal the delivery of healthcare in a manner consistent with the moral rules and the moral ideals. Towards this end, CEC pursues the instrumental ends of clarifying the limits of acceptable ethical disagreement and facilitating a choice among ethically acceptable alternatives. In pursuing these ends, healthcare ethics consultation (HEC) and CEC services confront three broad categories of questions: (1) questions of professional duty; (2) questions of law; and (3) questions of general morality. ⋯ We submit that this has implications for the organization and structure of consultation services and HEC and for the methodology and processes employed in CEC. Thus: (1) questions of professional duty should be addressed only by physician members (whom we would distinguish by employing the term "ethicians") of the HEC or CEC service. The only role for non-ethicians under these circumstances would be in helping to resolve disagreements between/among professionals; (2) questions of law, in contrast, should be addressed only by the attorney member(s) of the HEC or CEC service; (3) questions of general morality may be addressed by the entire membership of the HEC or CEC service.

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.

Human albumin solutions are used in a range of medical and surgical problems. Licensed indications are the emergency treatment of shock and other conditions where restoration of blood volume is urgent, burns, and hypoproteinaemia. Human albumin solutions are more expensive than other colloids and crystalloids. ⋯ There is no evidence that giving human albumin to replace lost blood in critically ill or injured people improves survival when compared to giving saline. Trauma, burns or surgery can cause people to lose large amounts of blood. Fluid replacement, giving fluids intravenously (into a vein), is used to help restore blood volume and hopefully reduce the risk of dying. Blood products (including human albumin), non-blood products or combinations can be used. The review of trials found no evidence that albumin reduces the risk of dying. Albumin is very expensive in which case it may be better to use cheaper alternatives such as saline for fluid resuscitation.

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.
