A narrative review: Resuscitation of older adults with hemorrhagic shock.

Abstract

Background: The increasing population of older adults presents unique challenges in trauma care due to their reduced physiologic reserve compared to younger patients. Trauma-induced hemorrhage remains a leading cause of mortality, yet there is a significant gap in the optimal management of hemodynamically unstable older adults. This review aims to synthesize current literature on resuscitation strategies, coagulopathy, triage, and the impact of timely interventions in older adult trauma patients experiencing hemorrhagic shock.

Study design and methods: A comprehensive narrative review was conducted following PRISMA-Scr guidelines. A systematic literature search was performed using PubMed, Scopus, and Web of Science databases, yielding 380 titles. After removing duplicates, 287 unique articles were screened, of which 120 full-text articles were reviewed. A total of 45 studies met the inclusion criteria and were analyzed. Studies were categorized based on resuscitation protocols (14 studies), coagulopathy management (7 studies), frailty and aging physiology (10 studies), and timing/triage in trauma care (14 studies).

Results: Studies highlight the effectiveness of the shock index (SI) over traditional vital signs for identifying hemodynamic instability in older adults. Balanced transfusion ratios and whole blood resuscitation show potential benefits, though data specific to older adults remain limited. Goal-directed resuscitation protocols improve outcomes by addressing the unique physiological needs of this population. While trauma-induced coagulopathy rates are similar across age groups, older adults frequently present with pre-existing anticoagulation, complicating management. Standardized care pathways, early activation of massive transfusion protocols (MTP), and tailored resuscitation approaches are critical for optimizing care.

Discussion: The growing geriatric trauma population necessitates improved resuscitation strategies tailored to their unique physiological responses. While balanced transfusions and goal-directed protocols have demonstrated efficacy, further research is required to refine these interventions specifically for older adults. Establishing standardized resuscitation guidelines and defining futility criteria will enhance decision-making and improve outcomes for this vulnerable population.
