Introduction: Traumatic pelvic fractures in unstable patients represent a high-risk clinical scenario in which severe pain, hemorrhagic shock, mechanical pelvic instability, associated visceral injury, and the need for urgent procedural care frequently coexist. Pain management in this population cannot be treated as an isolated pharmacological problem, because analgesic choices must remain compatible with resuscitation, airway safety, neurologic reassessment, hemorrhage control, and definitive pelvic stabilization.
Objective: The main objective of this systematic review was to evaluate evidence on pain management strategies for adult patients with traumatic pelvic fractures, with emphasis on hemodynamically unstable or physiologically vulnerable patients. Secondary objectives included assessment of systemic analgesia, ketamine-based opioid-sparing strategies, regional anesthesia, stabilization-related analgesia, interaction with hemorrhage-control pathways, and evidence gaps for future research.
Methods: A systematic search was conducted in PubMed, Scopus, Web of Science, Cochrane Library, LILACS, ClinicalTrials.gov, and the International Clinical Trials Registry Platform. Eligible studies included human clinical studies, systematic reviews, trauma guidelines, cohort analyses, and clinically relevant reviews published within the last five years, with expansion to ten years allowed if fewer than ten eligible studies were identified. Study selection, data extraction, risk-of-bias assessment, and certainty-of-evidence evaluation followed PRISMA-based methodology, using RoB 2, ROBINS-I, QUADAS-2 when applicable, and GRADE principles.
Results and Discussion: Twenty studies were included in the final qualitative synthesis. The available evidence showed that pain control in unstable pelvic trauma is inseparable from early pelvic stabilization, hemorrhage control, blood product resuscitation, and multidisciplinary trauma coordination. Opioids remain useful for rapid titratable analgesia, but opioid-sparing strategies, particularly ketamine-based regimens, may reduce opioid exposure in selected monitored patients. Regional anesthesia may provide meaningful analgesia in trauma care, but its role in unstable pelvic fractures is limited by incomplete anatomical coverage, coagulopathy, neurologic monitoring requirements, positioning constraints, and procedural urgency. The certainty of evidence was moderate for stabilization and hemorrhage-control principles, but low to very low for direct comparisons between analgesic strategies in unstable pelvic fracture patients.
Conclusion: Pain management in unstable traumatic pelvic fractures should be staged, multimodal, physiology-centered, and integrated with damage-control priorities. The most defensible strategy combines early stabilization and hemodynamic resuscitation with titratable systemic analgesia, selective ketamine use, cautious consideration of regional anesthesia, and longitudinal planning for rehabilitation and chronic pain prevention. Future studies should incorporate standardized pain outcomes, opioid consumption, regional anesthesia exposure, respiratory events, delirium, mobilization, and patient-reported recovery into pelvic trauma research.
