Cerebral vasospasm remains one of the leading causes of mortality in patients who experience a subarachnoid hemorrhage but survive the initial 24 hours. Vasospasm generally occurs 3-4 days after the initial subarachnoid hemorrhage and peaks at 5-7 days. The pathophysiology of vasospasm is poorly understood, which directly contributes to the inconsistency of management and creates a formidable challenge in clinical practice. ⋯ However, management of vasospasm varies among physicians and institutions mainly because of a lack of large clinical trials and inconsistent results. Practice has been based primarily on case reports and the preference of each practitioner. Several experimental therapies have been explored; however, large, prospective, randomized controlled trials are needed to elucidate the role of these therapies.

Despite published evidence supporting glycemic control in critically ill patients, achieving euglycemia remains a problem in the intensive care units (ICUs) of many institutions. Clinicians seeking to implement the findings of published evidence in their practice face many potential barriers that make euglycemia difficult to achieve in patients in the ICU. ⋯ Barriers to ICU glucose control include the role of different health professionals in glucose management, communication among health care professionals, guidelines, protocols, ICU culture, fear of hypoglycemia, glucose monitoring, education, systems analysis, health care resources, nutritional needs, and drug utilization. By ensuring compliance, changing ICU culture, developing guidelines and protocols, and incorporating a multidisciplinary approach, clinicians can achieve glycemic control in the critically ill population and improve patient outcomes.

Ventilator-associated pneumonia (VAP) is the most common infectious complication in patients receiving mechanical ventilation and accounts for exorbitant use of resources in the intensive care unit. Antimicrobial management of VAP incorporates an initial broad-spectrum, empiric regimen to ensure appropriate coverage with deescalation of therapy after 48-72 hours based on culture results and sensitivities. When VAP clinically responds to treatment, antimicrobials should be discontinued after 7-8 days to reduce overall antibiotic consumption and the selection pressure on flora observed in the intensive care unit and thus minimize the development and spread of antimicrobial resistance.
