概要

 Today we discuss the four potentially practice-altering papers that are the focus of EAST's Monthly Literature Review from February 2026. These recent medical articles highlight critical advancements in emergency trauma care across diverse patient populations and injury scenarios. Diagnostic algorithms for blunt trauma are being refined to minimize unnecessary radiation, with new rules emerging to guide cervical spine imaging in children and selective torso scanning in geriatric patients. Regarding acute surgical recovery, a large clinical trial determined that negative pressure wound therapy does not lower infection rates following emergency abdominal surgery compared to standard dressings. Furthermore, analysis of severe hemorrhage cases indicates that accelerating whole blood transfusions significantly enhances survival rates for trauma victims. Collectively, these studies aim to improve clinical outcomes by balancing aggressive life-saving interventions with more precise, evidence-based diagnostic protocols. PECARN prediction rule for cervical spine imaging of children presenting to the emergency department with blunt trauma: a multicentre prospective observational study. Leonard JC, Harding M, Cook LJ, et al. Lancet Child Adolesc Health. 2024 Jul;8(7):482-490. Scanning the aged to minimize missed injury: An Eastern Association for the Surgery of Trauma multicenter study. Ho V, Kishawi S, Hill H, et al. J Trauma Acute Care Surg. 2025 Jan 1;98(1):101-110. Negative Pressure Dressings to Prevent Surgical Site Infection After Emergency Laparotomy: The SUNRRISE Randomized Clinical Trial. SUNRRISE Trial Study Group; Atherton K, Brown J, Clouston H, Coe P, Duarte R, et al. JAMA. 2025 Mar 11;333(10):853-863. Timing to First Whole Blood Transfusion and Survival Following Severe Hemorrhage in Trauma Patients. Torres CMc, Kenzik KM, Saillant NN, Scantling DR, Sanchez SE, Brahmbhatt TS, Dechert TA, Sakran JV. JAM Surg. 2024 Apr 1;159(4):374-381.

Comprehensive Study Guide: Trauma Game Changers This study guide synthesizes recent clinical research regarding pediatric and geriatric trauma imaging, surgical site infection prevention in emergency laparotomy, and the timing of whole blood transfusions for severe hemorrhage. 1. Pediatric Cervical Spine Imaging: The PECARN Prediction Rule The Pediatric Emergency Care Applied Research Network (PECARN) conducted a multicenter prospective observational study to develop a clinical prediction rule for cervical spine (C-spine) imaging in children (ages 0–17) following blunt trauma. The goal was to reduce unnecessary radiation exposure while maintaining high sensitivity for injuries. Study Methodology and Scope Population: 22,430 children across 18 specialized pediatric emergency departments in the United States.Design: The study utilized a derivation cohort (11,857 children) to identify risk factors and a validation cohort (10,573 children) to test the rule's efficacy.Follow-up: Patients were tracked for 21–28 days post-injury to ensure no missed diagnoses. The Tiered Imaging Algorithm The PECARN rule suggests a tiered approach based on the severity of clinical findings: Tier 1: Factors Prompting CT Imaging (High Risk) Glasgow Coma Scale (GCS) score of 3–8.Unresponsive status on the AVPU (Alert, Verbal, Pain, Unresponsive) scale.Abnormal airway, breathing, or circulation (ABCs).Focal neurological deficits (e.g., paresthesia, numbness, or weakness). Tier 2: Factors Prompting Plain Film X-Ray (Non-Negligible Risk) GCS score of 9–14.Responsiveness only to verbal or painful stimuli on the AVPU scale.Neck pain or midline neck tenderness."Substantial" head or torso injury (defined as injuries warranting surgery or inpatient observation). Outcomes and Impact Sensitivity and Predictive Value: The rule demonstrated a 99.9% negative predictive value and 94.3% sensitivity in the validation cohort.Reduction in Radiation: Application of this rule would have decreased the use of neck CT scans from 17.2% to 6.9% without an appreciable rate of missed injuries. -------------------------------------------------------------------------------- 2. Geriatric Blunt Trauma Imaging: The EAST Multicenter Study Research conducted by the Eastern Association for the Surgery of Trauma (EAST) addressed the lack of evidence-based guidance for imaging geriatric patients (aged 65 and older) who have experienced blunt trauma. Clinical Findings and Recommendations The study analyzed over 5,000 patients, approximately two-thirds of whom were victims of ground-level falls. The research aimed to determine ...
