Pain Management Following Trauma and Burns

Analgesia for trauma and burns

This article has described the physiologic impact of trauma- and burn-related pain as well as the effect of a clinician's choice of analgesic method, using the specific example of regional analgesia for pain caused by chest trauma. It has been observed that trauma exerts a holistic influence upon the organism, marshalling reflexes, multi-system physiologic stress responses, and psychologic responses--some adaptive and others maladaptive. There is reason to consider that timely analgesia can intervene in this dynamic process and interdict the establishment of a debilitated state. A key finding of these studies is that a report of pain relief may not be the best outcome measure since the choice of analgesic method(s) has a significant impact on the secondary effects of pain. Although extrapolated from studies of perioperative pain, findings do suggest that there may be a critical period of time during which the secondary effects of a painful stimulus may be attenuated or reversed. How long this period of reversibility exists has not been determined, so planning for the level and goals of analgesia intervention should occur early on. Analgesia should be viewed not only as a humanitarian gesture, but also a therapeutic maneuver with the goal being the early restoration of function and the mitigation of a chronic debilitated state. There is scattered evidence that regional analgesic techniques using local anesthetics have some advantages over other analgesic modalities, particularly in the trauma patient with pulmonary compromise; however, as with other medical interventions, one should develop a strategic plan of application which includes consideration of potential complications and side effects, in addition to the potential therapeutic effects. The traumatized body, as well as the attending physician, must deal with inflammation, the neurohumoral reaction, musculoskeletal reflex responses, and numerous other reactions designed to stabilize an acutely destabilized systemic entity. Multimodal analgesia, with the balanced use of systemic and regional medications, has given the best short- and long-term results in studies of postthoracotomy pain. The use of a similar combined plan for posttraumatic analgesia seems logical; however, many questions remain as yet unanswered. In particular, what are the optimal combinations of techniques/medications to employ to maximize analgesia and minimize secondary effects of trauma? Can an aggressive multimodal approach intervene effectively in the development of chronic pain states, and if so, for how long? What are the long-term benefits to be derived from making a significant impact on the stress response? Last, but not least, can analgesic interventions be shown to be cost-effective according to current societal pressures to reduce the cost of health care? These and other questions are not easy to answer. Trauma strikes, in a variable fashion, patients of all ages, with all forms of comorbidity, and is treated by a technology that continues to evolve. Previous research related to the effects of analgesic treatments has been hampered by the limitations that arise when isolated groups embark on vast projects with limited numbers of patients available. It is time for investigators at multiple centers to embark on coordinated efforts to address long-term questions related to trauma and the therapeutic efficacy of analgesia.

Management of pain in the critically ill patient

In spite of growing evidence that effective pain management of critically ill human beings decreases their morbidity and mortality, pain is often undertreated in critically ill animals. Reasons for withholding analgesics in these animals have included fear of contributing to cardiopulmonary instability and difficulty in monitoring response to therapy. Appropriately used, analgesics improve the status of critically ill animals. Opioids are the most widely used analgesics but other options exist. Newer methods of analgesic administration include continuous infusions, epidural, local, regional, and transdermal administration.

Emotional and psychosocial factors in burn patients during hospitalization

This is a preliminary study of psychological symptoms, prior psychosocial adjustment and severity of injury in 25 consecutive burn patients. All had suffered burns in work-related accidents and were evaluated by the psychiatric consulation-liaison team during their initial hospitalization in the Burn Unit of the Hospital del Trabajador, Santiago. All patients were clinically evaluated and the following instruments were applied: Hamilton Scales of Anxiety (HAM-A) and Depression (HAM-D), Goldberg's General Health Questionnaire (GHQ-28), Cloninger's Tridimensional Personality Questionnaire (TPQ) and a modified version of a Schooler's Adjustment Scale. No significant correlation was found between extent and severity of burns and anxious or depressive symptoms. However, all patients had burns that varied from mild to moderate; there were no severe and extensive injuries. A significant correlation was found between anxiety and the harm avoidance dimension in the TPQ, as would be expected. Patients with poor psychosocial adjustment presented with greater anxiety symptoms. A significant negative correlation was also found between degree of anxiety symptoms and income level. The main findings are in agreement with current literature. They emphasize the relevance of prior psychosocial adjustment and personality as probable factors of psychological symptoms. The need to control pain as a variable is also pointed out.

The complexities of managing severe burns with associated trauma

A high incidence of severe inhalation injuries can be expected in the combined injury patient. The initial management remains attention to the ATLS priorities of airway, breathing, and circulation, with prompt and safe transfer to a regional center of excellence. The treatment of either the burn or the associated injuries may be compromised by their combined presence, and a team approach is essential to their optimal management. Circulatory management goals based on oxygen consumption and delivery allow greater understanding and control of the physiologic demands placed on the patient by the disease process. The management of inhalation injury and ARDS is at an exciting turning point in history, and we now have in hand and use many techniques that allow salvage of these mortal conditions. Pain management is essential to humane care and requires frequent assessment and patient control to be effective. Rehabilitation of the burn and trauma patient starts on the day of injury and requires team dedication to the areas of greatest morbidity early in the planning of surgical priorities and physical therapy.
