This study was designed to investigate the clinical efficacy of fluoroscopically guided therapeutic cervical selective nerve root blocks (SNRBs) in patients with whiplash induced cervical radicular pain. Study design was restrospective with independent clinical review. Twenty two patients were included. ⋯ Good or excellent results were observed in 14% of patients. In higher functioning individuals a significantly greater (F=.0427) improvement in pain of 48.9% was observed. In these initial findings suggest that fluoroscopically guided therapeutic SNRBs, except possibly for higher functioning individuals, are not effective in the treatment of whiplash induced cervical radicular pain.

To review the clinical use of noninvasive positive pressure ventilation (NPPV) in both acute hypoxic and hypercarbic forms of pediatric respiratory failure, including its mechanism of action and implementation. DATA SOURCES: Studies were identified through a MEDLINE search using respiratory failure, pediatrics, noninvasive ventilation, and mechanical ventilation as key words. STUDY SELECTION: All original studies, including case reports, relating to the use of noninvasive positive pressure in pediatric respiratory failure were included. Because of the paucity of published literature on pediatric NPPV, no study was excluded. DATA EXTRACTION: Study design, numbers and diagnoses of patients, types of noninvasive ventilator, ventilator modes, outcome measures, and complications were extracted and compiled. DATA SYNTHESIS: For acute hypoxic respiratory failure, all the studies reported improvement in oxygenation indices and avoidance of endotracheal intubation. The average duration of NPPV therapy before noticeable clinical improvement was 3 hrs in most studies, and NPPV was applied continuously for 72 hrs before resolution of acute respiratory distress. In patients with acute hypercarbic respiratory failure, application of NPPV resulted in reduction of work of breathing, reduction in CO(2) tension, and increased serum bicarbonate and pH. These patients are older than patients in the acute hypoxic respiratory failure group and, in addition to improved blood gas indices, they reported improvement in subjective symptoms of dyspnea. Improvement in gas exchange abnormalities and subjective symptoms occurred within the same time span (the first 3 hrs) as in the acute hypoxic respiratory failure group. However, use of noninvasive techniques in patients with acute hypercarbic respiratory failure continued after resolution of acute symptoms. Complications related to protracted use of NPPV were common in this group. ⋯ NPPV has limited benefits in a group of carefully selected pediatric patients with acute hypoxic and hypercarbic forms of respiratory failure. The routine use of this technique in pediatric respiratory failure needs to be studied in randomized controlled trials and better-defined patient subsets.

The practice guidelines for interventional techniques in the management of chronic pain are systematically developed statements to assist physician and patient decisions about appropriate health care related to chronic pain. These guidelines are professionally derived recommendations for practices in the diagnosis and treatment of chronic or persistent pain. They were developed utilizing a combination of evidence and consensus based techniques, to increase patient access to treatment, improve outcomes and appropriateness of care, and optimize cost-effectiveness. ⋯ These guidelines do not constitute inflexible treatment recommendations. It is expected that a provider will establish a plan of care on a case-by-case basis, taking into account an individual patient's medical condition, personal needs, and preferences, and the physician's experience. Based on an individual patient's needs, treatment different from that outlined here could be warranted.

Models of critical care delivery: physician staffing in the ICU.
Although a consensus has emerged over the value of intensive care units (ICUs) in improving both the outcome and efficiency of critical care, the optimal staffing configuration of physicians who provide this care remains controversial. The value of open ICUs, where many clinicians can admit and care for patients, versus closed ICUs, where an on-site intensivist or housestaff team (or both) provides primary care of the critically ill patient is one aspect of this controversy. The roles of the intensivist, the ICU housestaff team, and the ICU director have also been debated. This article reviews the available literature on physician staffing in critical care units and its relationship to outcome and cost-effectiveness of care.

Current evidence suggests that, in a small subset of acute stroke patients who can be treated within 3 hours of symptom onset, the administration of tissue plasminogen activator (tPA) confers a modest outcome benefit, but that this benefit is associated with an increased risk of intracranial hemorrhage that can be severe or fatal. The data show that tPA therapy must be limited to carefully selected patients within established protocols. Further evidence is necessary to support the widespread application of stroke thrombolysis outside research settings. ⋯ In such centres, emergency physicians should identify eligible patients, initiate low risk interventions and facilitate prompt computed tomography. Only physicians with demonstrated expertise in neuroradiology should interpret head CT scans used to determine whether to administer thrombolytic agents to stroke patients. Neurologists should be directly involved prior to the thrombolytic administration.
