PRIMARY SURVEY WITH RESUSCITATION 217 determinant of mortality, host factors also played a significant role. Common mechanisms of injury encountered in older patients include falls, motor vehicle crashes, burns, and penetrating injuries. Falls The risk of falling increases with age, and falls are the most common mechanism of fatal injury in the elderly population. Nonfatal falls are more common in women, and fractures are more common in women who fall. Falls are the most common cause of traumatic brain injury (TBI) in the elderly. Nearly one-half of deaths associated with ground-level falls are a result of TBI. One-half of elderly patients suffering a hip fracture will no longer be able to live independently. Risk factors for falls include advanced age, physical impairments, history of a previous fall, medication use, dementia, unsteady gait, and visual, cognitive, and neurological impairments. Environmental factors, such as loose rugs, poor lighting, and slippery or uneven surfaces, play an additional role in fall risk. Motor Vehicle Crashes In general, older people drive fewer total miles, on more familiar roads, and at lower speeds than younger drivers. They also tend to drive during the day. Thus most of the elderly traffic fatalities occur in the daytime and on weekends, and they typically involve other vehicles. Contributing risk factors in the elderly for motor vehicle crashes include slower reaction times, a larger blind spot, limited cervical mobility, decreased hearing, and cognitive impairment. Additionally, medical problems such as myocardial infarction, stroke, and dysrhythmias can result in conditions that precipitate a collision. Burns MechANism of Injury Burn injury can be particularly devastating in elderly patients. The impact of age on burn mortality has long been recognized; however, despite significant declining mortality in younger age groups, the mortality associated with small- to moderate-sized burns in older adults remains high. In examining deaths from structural fires, researchers find the elderly are particularly at risk because of decreased reaction times, impaired hearing and vision, and the inability to escape the burning structure. Spilled hot liquids on the leg, which in a younger patient may re-epithelialize due to an adequate number of hair follicles, will result in a full-thickness burn in older patients with a paucity of follicles. Their aging organ systems have a major impact on the outcomes of elderly burn patients; changes in the skin are obvious, but the patient’s inability to meet the physiological demands associated with burn injury likely has the most influence on outcome and survival. Penetrating Injuries By far, blunt trauma is the predominant mechanism of injury in older adults; however, a significant number of people over the age of 65 years are victims of penetrating injury. In fact, penetrating injury is the fourth most common cause of traumatic death in individuals 65 years and older. Many deaths associated with gunshot wounds are related to intentional self-harm or suicide. As with all trauma patients, the application of ATLS principles in assessment and management of older adults follows the ABCDE methodology. Clinicians must take into consideration the effects of aging on organ systems and their implications for care, as outlined in n TABLE 11-1. (Also see Effects of Aging on MyATLS mobile app.) Airway Primary Survey with Resuscitation The elderly airway poses specific challenges for providers. Given that older adults have significant loss of protective airway reflexes, timely decision making for establishing a definitive airway can be lifesaving. Patients may have dentures that may loosen and obstruct the airway. If the dentures are not obstructing the airway, leave them in place during bag-mask ventilation, as this improves mask fit. Some elderly patients are edentulous, which makes intubating easier but bag-mask ventilation more difficult. Arthritic changes may make mouth opening and cervical spine management difficult (n FIGURE 11-2). When performing rapid sequence intubation, reduce n BACK TO TABLE OF CONTENTS
