Tracheobronchitis presents with a heavy gram-positive colonization, putting patients at risk for gram-positive pneumonia. Urinary Tract Infections Urinary tract infections can be classified into upper and lower urinary tract infec- tion. True pyelonephritis is very rare in burn patients; however, lower urinary tract infection can occur as a result of a chronic indwelling Foley catheter. Urinary tract infections are diagnosed based on positive culture greater than 1 105 organisms cultured from a urine specimen. Urinalysis may reveal white cells and cellular debris associated with active infection. Positive urinary cultures are common during the course of sepsis, and they are also treated in the general context of that particular septic episode. It must be noted, however, that the association of clinical signs of sepsis with burn wound cultures or blood cultures with positive urinary cultures make the final diagnosis of sepsis. Other information about organ involvement, such as positive findings on funduscopic examination, is necessary to make this diagnosis. In general, isolated urinary tract infections are treated with appropriate systemic therapy with good urinary extraction. If there is suspi- cion of an ascending infection or sepsis, more aggressive treatment with prolonged systemic antimicrobials is warranted. Catheter Related Infections Central and arterial line placement, catheter care, and protocol have been dis- cussed in Chapter 1. Catheter-related sepsis is associated with prolonged indwell- ing central and arterial catheters. Catheter sepsis may be primary, in which the General Treatment 53 catheter is the original focus of infection; or secondary, in which the catheter tip is seeded and serves as a nidus for continued shedding of micro-organisms into the bloodstream. Lines can be associated with the development of both gram- negative and gram-positive sepsis. Central and arterial lines represent an avascular foreign body and, as such, are prone to microbial seeding. Infectious complica- tions associated with indwelling catheters represent a major problem. Burned patients appear to be especially susceptible to this complication, with rates quoted as high as 50%. There is a strong correlation between micro-organisms recovered from catheter tips and skin flora, and pathogens can be traced in up to 96% of cases to bacteria isolated in the burn wound. The former supports the idea that bacteria migrate down the catheter to the tip. Persistent positive blood cultures, redness and purulent discharge around catheter insertion, and persistent high fever without other signs or sites of sepsis should arise the suspicion of catheter-related sepsis. Contemporary cultures from the central line and peripheral blood semi- quantitative culture aid in the diagnosis, although many physicians choose to remove of the suspected infected line and catheter tip culture. Treatment involves removal of all infected lines and placement of new lines through new sites. Suppu- rative thrombophlebitis should be suspected in patients who do not recover from the septic episode and show persistent positive cultures despite appropriate treat- ment. Immediate operative excision of the affected vein to the port of entry into the central circulation and packing of subcutaneous tissue are essential for the treatment of this complication. Other sources of septic complications in burned patients that need to be ruled out include the following: Acalculous cholecystitis Cholangitis Regional enteritis Necrotizing enterocolitis Pancreatitis Suppurative thrombophlebitis Pelvic infections Suppurative chondritis Subacute bacterial endocarditis Suppurative sinusitis BIBLIOGRAPHY 1. Sherwood Shriners Hospital for Children and the University of Texas Medical Branch, Galveston, Texas, U. INTRODUCTION Inhalation injury is a nonspecific term describing the harmful effects of aspiration of any of a large number of materials that can damage the airways or pulmonary parenchyma. Inhalation injury is produced by either thermal or chemical irritation due to aspiration of smoke, burning embers, steam, or other irritant or cytotoxic materials in the form of fumes, mists, particulates, or gases. The damage can be the result of direct cytotoxic effects of the aspirated materials or secondary injury due to an inflammatory response. In addition to damage to the airways and pulmo- nary parenchyma, inhalation of toxic substances such as carbon monoxide or cyanide can produce harmful systemic effects.

Craig Department of Psychology, University of British Columbia Thomas Hadjistavropoulos Department of Psychology, University of Regina Controversies abound concerning the role of psychological features of pain and their use in pain management. Although pain has been clearly identi- fied as a psychological experience, one does not have to spend much time talking to people or reading the literature to discover disagreements about the nature of this experience. Contested issues include a willingness to dis- miss the importance of patient thoughts and feelings, questions about the meaning of behavioral displays of pain, debates about the role of social contexts, disagreements about how one should assess pain, and whether and how one should attempt to control painful distress. Similar disagree- ments concerning pain mechanisms and intervention approaches are found when considering anthropological, nursing, pharmacological, surgical, neurophysiological, genetic, or any other perspective on pain; however, the focus here is on psychological processes. Roots of dissension concerning models of pain and pain management are found in persistent and uncontrolled pain. Pain remains a very serious problem with highly debilitating and destructive consequences for large numbers of people. Almost everyone can anticipate episodes of poorly con- trolled acute pain in their future, and there are distressingly high numbers of patients with persistent or recurrent pain. Both signal the failures of cur- rent explanatory models and the inadequacies of current applications of treatment or palliative interventions, despite numerous advances in our un- derstanding of biological, psychological, and social mechanisms in pain and 303 304 CRAIG AND HADJISTAVROPOULOS improved pain control strategies (Wall & Melzack, 2001). There should be urgency and contention in the field until a better measure of pain control is accomplished. Indeed, it seems surprising that the inadequacies of our un- derstanding of pain and our limitations in controlling pain are not more widely understood or publicized, and that they are not greater sources of scientific, practitioner, and public unrest. Recent decades have seen concerted efforts to provide an evi- dence-based understanding of pain, and to improve utilization of these un- derstandings by practitioners. Many of the recent advances have resulted from the inspiration and leadership of John Bonica (1953; Loeser, Butler, Chapman & Turk, 2001), the integrative perspective and heuristic benefits of the gate control theory of pain (Melzack & Wall, 1965), and the organiza- tional structure and impetus generated by the founding of the International Association for the Study of Pain in 1974 (http://www. Many factors contribute to differences of opinion in our understanding of pain and pain management. Scholars from numerous disciplines, includ- ing the humanities and the biological, behavioral, and social sciences, as well as health care professionals with diverse education and commitments, all bring varied perspectives to the challenges of understanding a broad range of issues and untested concepts about the nature of pain and pain management. The tragedies of uncontrolled pain and suffering have en- gaged humans throughout evolutionary history in varied, and sometimes isolated, cultures around the globe; hence, varied views in different cul- tures and communities have emerged (Craig & Pillai, in press). Most of these views deserve respect, but no model has as yet proven wholly satis- factory. Nonetheless, the evidence-based perspective (McQuay, Moore, Moore, 1998) has great potential because methods of science are more ef- fective in identifying valid concepts and useful interventions than are trial and error solutions. In the developed world, there is a tendency to focus on technological un- derstandings and answers, in part because of the unfettered promise of bio- logical solutions. In addition, government agencies and the pharmaceutical industry provide generous resources to support this perspective. Although there have been celebrated successes in development of new analgesic pharmaceuticals, these often remain unavailable to the community at large, and sometimes the widespread potential of such discoveries appears exag- gerated. Dissatisfaction with biomedical approaches is reflected in the ma- jor resurgence of interest in alternative and complementary medicine and the substantial market share of health expenditures this sector has been able to capture in providing services to chronic pain patients who have not benefited from conventional western medical care. Essentially, failures of Western approaches to health care and urgent need for relief from pain have led to free-market competition.
