Using early FAST ultrasound drastically lowers mortality rates in severe trauma patients, proving essential in low-resource environments.

• In-hospital mortality: 39.2% with FAST vs. 66.2% without (p=0.001).
• Thirty-day mortality: 45.6% with FAST vs. 72.7% without (p=0.001).

Integrating FAST into trauma triage can enhance surgical outcomes significantly.

• Reduced CT scans (82.5% with FAST vs. 96.1% without, p=0.006) and faster time to surgery (5.16 vs. 9.82 hours, p<0.001).
