Are β-blockers anesthestics?

β-Blockers are associated with a reduction in COPD exacerbations.

BACKGROUND While some retrospective studies have suggested that β-blocker use in patients with COPD is associated with a reduction in the frequency of acute exacerbations and lower mortality, there is concern that their use in patients with severe COPD on home oxygen may be harmful. METHODS Subjects with Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage 2-4 COPD participatin...

β-Blockers in heart failure--are all created equal?

β-blockers in septic shock: are we there yet?

Septic shock is characterized by circulatory collapse and diminished tissue perfusion, leading to organ dysfunction in the setting of systemic infection. The mechanisms of septic shock are incompletely understood; moreover, its incidence is increasing, and its mortality remains unacceptably high. In addition to antimicrobial and supportive treatments, no other therapy has a survival benefit, de...

β-blockers for COPD inpatients.

For clinicians who treat patients with respiratory diseases, the use of β-blockers has, for a long time, posed a dilemma because of the potential risk of bronchospasm and neutralisation of the effectiveness of β-2 agonists. This predicament is particularly challenging for patients with chronic obstructive pulmonary disease (COPD), many of whom have substantial cardiovascular comorbidity, and in...

Hemangiomas and β-Blockers: On the Rebound.

Infantile hemangioma (IH) is the most common tumor of childhood, and although most lesions eventually involute, the proliferative phase may be associated with complications, such as ulceration, bleeding, functional compromise, and anatomic disfigurement. Rarely, IH can have major or life-threatening consequences, such as airway obstruction, high-output congestive heart failure, and consumptive ...
