At a time when the burn patient is often at his or her most lucid buy generic modafinil 100mg, intubation precludes effective communication so that the history is limited, the patient’s wishes cannot be expressed, and we cannot assess the patient’s ability to comprehend information. Heavy sedation is often required and under these circumstances muscle relaxants are used in some institutions. Deep sedation and muscle relaxation increase the morbidity and mortality of unintended extubations, which have been found more frequent in this patient population. In addition, irritation to the larynx by an endotracheal tube is synergistic with inhalation injuries in producing laryngeal and tracheal injuries. Prophylactic intubation of all patients at risk will include many who would not benefit from intubation. As a result, it is important to exercise good clinical judgement in identifying patients for intubation. In order to make this distinction it is necessary to recognize which patients are at risk, understand the clinical course of inhalation injuries, utilize objective measurements of airway compromise (such as endoscopy), and follow the patient with close observation and serial re-evaluations when needed. Several authors have concluded that clinical observations are not suffi- ciently sensitive or specific to identify reliably which patients will develop pro- gressive edema and respiratory insufficiency due to the resultant obstruction. Clinical evaluation has been reported to either underestimate or overestimate the severity of inhalation injury and supraglottic edema [4,5]. An additional valuable observation of these studies is that when adequate resources are available, it is safe to observe without intubating select patients who are at risk for inhalation injury. Clinicians at the Baltimore Regional Burn TABLE 7 Risks Associated With Unnecessary Intubations in Burn Patients Intubation precludes effective communication with the patient. Distorted anatomy and perceived urgency make traumatic or failed intubation more likely. Endotracheal tubes are difficult to secure and incidence of self-extubation is high in acute burn patients. Acute burn patients are often agitated after intubation and require heavy sedation, making unplanned extubation more dangerous. Inhalation injury and mechanical trauma from the endotracheal tube are synergis- tic in producing laryngeal and tracheal injuries. FIGURE 4 Frequency distribution of signs and systems of inhalation injury in 11 patients exposed to smoke and/or fire who presented without evidence of airway obstruction or respiratory distress.

Center proposed an algorithm for airway management of burn patients at risk for airway compromise (Fig. Initial ATLS survey can identify patients with impending respiratory failure or airway obstruction. These patients can be intu- bated before their airway status deteriorates further. Other patients at risk for inhalation injury but without obvious obstruction and distress initially can be evaluated endoscopically for direct evidence of airway obstruction. When available, flexible fiberoptic endoscopy is very well tolerated by patients. Adults can be examined under topical local anesthesia and sedation as needed. At our pediatric burn hospital, examinations are safely performed with patients under ketamine sedation and topical local anesthesia.

Prevailing disease management approaches to prevention and healthcare delivery do not adequately address the symptoms and disability that occur among war veterans in the weeks discount modafinil 200 mg with visa, months generic modafinil 200mg with mastercard, and years following wartime envi- ronmental and psychosocial exposures. There is, therefore, a critical need for innovative and comprehensive models that can better address postwar pain, fatigue, depression, and other idiopathic symptoms. This need is particularly poignant given the recent return of US and UK military forces to Iraq and the mission to remain there during the postwar period. Can we prevent what may become the latest in the long line of postwar syndromes or are we destined for a second version of the ‘Gulf War syndrome’? Our objectives in this article are to: (1) elaborate a model of postwar healthcare that targets the impact of postwar pain, fatigue, depression, and other idiopathic symptoms on relevant individuals and populations, (2) describe examples of US attempts to develop and adopt the model in the years since the 1991 Gulf War, and (3) discuss future public health and health services research initiatives necessary to sustain, further develop, and improve implementation efforts.

These chronic symptoms and many other idiopathic symptoms and syndromes are a significant problem in general. Conservative estimates suggest that 25–30% of people’s symptoms are idiopathic. Primary care physicians identify a medical explanation for symptoms in less than 1 of 7 patients in whom a medical explanation is not apparent during the initial visit and associated evaluation. Chronic pain, fatigue and other idiopathic symptoms increase healthcare use but usual invasive medical approaches applied to these symptoms lead more often to iatrogenic harm, patient dissatisfaction, and provider frustration than medical benefit or patient reassurance [12, 13]. Chronic symptoms, idiopathic or not, contribute substantially to patient levels of disability [14, 15]. Chronic pain, fatigue, and other idiopathic symptoms are a source of substantial population morbidity. These symptoms and associated disability often lead to and are produced by distress, worry, anxiety, and depression [16–19]. These symptoms vary widely in severity from single symptoms that are mild and transient to multiple symptoms that are chronic, and disabling. Clinical outcomes related to chronic pain, fatigue and other idiopathic symptoms are strongly correlated with biopsychosocial influences that may be characterized as predisposing, precipitating, and perpetuating factors (see table 1) [21, 22]. Similarly, clinical approaches can either mitigate chronic pain, fatigue and other idiopathic symptoms, or they can worsen and perpetuate them. Research has identified evidence-based treatments for chronic pain, fatigue and associ- ated disability [23, 24]. Alternatively, differing provider and patient explana- tions for these symptoms and disability contribute to the frustration and dissatisfaction with care consistently observed in empirical studies [25–27]. If a healthcare visit for chronic pain or fatigue occurs in the context of commu- nity debate over cause of or blame for symptoms and disability, the provider- patient relationship may be more likely than usual to become strained, outwardly adversarial, or result in mutual rejection [28, 29]. At other times, the provider may unwittingly overrespond to these symptoms, embarking on an overly aggres- sive quest for causes, an approach that often leads to iatrogenic harm rather than symptom relief. A bad healthcare encounter may foster provider-patient differences, disagreements, and mistrust over symptoms that tend to mirror overarching community debates. Alternatively, collaborative negotiation of differing physician-patient perceptions of illness and development of a mutu- ally acceptable model of illness may lead to increased patient satisfaction and decreased physical health concern. The next part of this paper attempts to parlay this current understanding of chronic pain, fatigue and other idiopathic symptoms and into an effective model of postwar or postdisaster population-based healthcare. The Conceptual Basis of Population-Based Care The goal of population-based healthcare is to achieve maximum efficiency and effectiveness through an optimized mix of population-level and individual- level interventions.
