A decrement in evoked muscle force with repetitive nerve stimulation (fade) suggests impaired neuromuscular transmission. We tested the hypothesis that fade of pulmonary function, ie, a decrease in values of FVC with the second spirometric maneuver compared to the first maneuver, occurs during impaired neuromuscular transmission. ⋯ A clinically relevant fall (fade) in FVC from the first to the second value during or after neuromuscular blockade suggests impaired pulmonary function and may be due to muscle paralysis. For this reason, the first (best) FVC value may overestimate pulmonary function and expose the patient to an unidentified risk.

An increasing proportion of critically ill patients are elderly (ie, >or= 65 years of age). This poses complex challenges and choices for the management of elderly patients. Outcome following admission to the ICU has been traditionally concerned with mortality. ⋯ This article reviews the literature, published in English from 1990 to December 2003, pertaining to HRQOL and functional status outcomes of elderly patients. Functional status and HRQOL of elderly survivors of ICUs has been underinvestigated. There is no agreement as to the optimal instrument choice, and differences between studies preclude meaningful comparison or pooling of results.

Postoperative bleeding is a common complication following cardiothoracic surgical procedures requiring cardiopulmonary bypass (CPB). Serious bleeding complications requiring the administration of blood products, hemostatic drugs, and even repeat surgery are associated with considerable morbidity, mortality, and resource consumption. Therapy with recombinant activated factor VII (rFVIIa) may be an effective treatment strategy for patients with refractory bleeding. ⋯ In the remaining six patients, gradual hemostasis was achieved after a mean of 3.4 doses (mean cumulative dose, 225 microg/kg). Two patients (10%) were believed to have experienced thromboembolic complications after the administration of rFVIIa (one was fatal), and, in another patient, intracoronary thrombosis was suspected but was not confirmed. In patients experiencing postoperative bleeding complications that are refractory to treatment with blood products, hemostatic agents, and/or repeat surgery, the use of rFVIIa may be considered.

Clinical Trial
A multidisciplinary community hospital program for early and rapid resuscitation of shock in nontrauma patients.
To determine the effect of a community hospital-wide program enabling nurses and prehospital personnel to mobilize institutional resources for the treatment of patients with nontraumatic shock. ⋯ Similar to current practice in patients who have experienced trauma or cardiac arrest, the empowerment of nonphysician providers to mobilize hospital resources for the care of patients with shock is effective. A community hospital program incorporating the education of providers, the activation of a coordinated team response, and early goal-directed therapy expedited appropriate treatment and was temporally associated with improved outcomes. Randomized multicenter trials are needed to further assess the impact of the shock program on outcomes.

Ten-year cumulative incidence of COPD and risk factors for incident disease in a symptomatic cohort.
To determine the 10-year cumulative incidence of COPD in a cohort of subjects with respiratory symptoms (Global Initiative for Chronic Obstructive Lung Disease [GOLD] stage 0) using the British Thoracic Society (BTS) and GOLD spirometric criteria. Furthermore, we sought to evaluate risk and gender factors for incident COPD. ⋯ In this cohort, the 10-year cumulative incidence of COPD was 8.2% (using BTS criteria) and 13.5% (using GOLD criteria). Increasing age, smoking, and bronchitic symptoms, but not gender, were risk factors for incident COPD. GOLD stage 0 therefore appears to identify subjects who are at risk of COPD, but men and women presented different risk profiles.
