Geriatrik Travmalar ve Yaklaşımı
Özet
Dünya genelinde 65 yaş ve üzeri geriatrik nüfus, artan yaşam beklentisi ve azalan doğum oranları gibi nedenlerle hızla artmaktadır. Yaşlanmayla beraber tüm organ sistemlerinde meydana gelen fizyolojik rezerv azalması, anatomik değişiklikler ve eşlik eden kronik hastalıklar, yaşlı hastaların travmaya verdiği yanıtı olumsuz etkileyerek mortalite ve morbidite riskini ciddi oranda artırmaktadır. Geriatrik travmalarda en sık karşılaşılan yaralanma mekanizmaları düz zeminde düşmeler ve motorlu taşıt kazalarıdır; bunu yanıklar ile yaşlı istismarı takip etmektedir. Fizyolojik yaşlanmaya bağlı olarak kardiyovasküler sistemde taşikardi yanıtının gecikmesi, solunum kompliyansının azalması, kemik yoğunluğunun kaybıyla ortaya çıkan osteoporotik kırıklar ve beyin dokusunun küçülmesiyle artan intrakraniyal kanama riskleri acil yaklaşımı karmaşıklaştırmaktadır. Bu hastaların birincil ve ikincil değerlendirmelerinde hayati bulgular yanıltıcı olabileceğinden, sistolik kan basıncının 110 mmHg’nin altında olması doğrudan şok göstergesi kabul edilmelidir. Erken dönemde kontrast dışı beyin bilgisayarlı tomografisi ve toraks tomografisi gibi ileri görüntüleme yöntemlerinin kullanılması tanısal açıdan kritik önem taşır. Tedavi yönetiminde, yaşlıların dekompanse olmasını önlemek amacıyla kristaloid sıvı resüsitasyonu ve erken kan transfüzyonları dikkatle uygulanmalı, hastaların yaygın olarak kullandığı antikoagülan ve antiagregan ilaç profilleri kanama risk analizi kapsamında titizlikle yönetilmelidir.
The geriatric population, defined as individuals aged 65 and older, is expanding globally due to prolonged life expectancy and declining birth rates. Anatomical and physiological changes across all organ systems, combined with a higher prevalence of chronic comorbidities, significantly reduce the capacity of elderly patients to tolerate injury stress, resulting in higher mortality and morbidity rates compared to younger cohorts. Falls and motor vehicle accidents constitute the primary mechanisms of injury in geriatric trauma, followed by burns and elder abuse. Age-related physiological alterations, such as a delayed tachycardic response to hypovolemia, decreased respiratory compliance, fragile osteoporotic fractures, and increased intracranial space secondary to cerebral atrophy, complicate emergency assessments. Initial and secondary evaluations can be highly misleading; therefore, a systolic blood pressure below 110 mmHg must be recognized as an early sign of shock. Advanced imaging modalities, including non-contrast cranial computed tomography and thoracic CT, are essential for avoiding delayed diagnoses. Management requires meticulous crystalloid fluid resuscitation and early blood transfusions to prevent volume overload, alongside a rigorous risk analysis regarding the reversal of pre-injury anticoagulant and antiplatelet therapies.
