How Timing of Regional Anesthesia Impacts Outcomes in Traumatic Rib Fracture Patients: A Trauma Quality National...

Area of Science:

• Trauma Surgery
• Anesthesiology
• Critical Care Medicine

Background:

• Rib fractures are common traumatic injuries with high morbidity and mortality.
• Effective pain management, often requiring regional anesthesia (RA), is crucial for recovery.
• Optimal timing for RA administration in rib fracture patients remains understudied.

Purpose of the Study:

• To evaluate the impact of regional anesthesia timing on patient outcomes in isolated chest trauma.
• To identify the optimal time window for RA administration to improve hospital length of stay and reduce complications.

Main Methods:

• Utilized data from the 2021 Trauma Quality National Improvement Program registry for isolated chest trauma patients.
• Categorized patients based on RA administration time: <4h, <12h, <24h, and >24h from admission.
• Employed nearest neighbor matching and statistical tests (median two-sample, Fisher exact) to compare outcomes.

Main Results:

• Patients receiving RA within 4 hours showed a significant decrease in hospital length of stay (5 vs. 7 days).
• Earlier RA administration (<12h, <24h) also correlated with reduced hospital length of stay.
• Administration of RA more than 24 hours post-admission resulted in a 2.5-fold increase in unplanned ICU admissions.

Conclusions:

• Administering RA within 24 hours of presentation is associated with fewer ICU admissions.
• Earlier RA administration (<4 hours) demonstrates the greatest reduction in hospital length of stay.
• While RA within 4 hours offers maximum benefit, a 24-hour window is a more achievable clinical target, still significantly reducing ICU admissions.
