Description
Emergency surgery patients die in hospital more often than anyone wants, and a number already on the chart during the operation may foretell it. Yibo Fu and co-authors test peak intraoperative lactate in a 2025 study of 2,452 non-cardiac emergency cases at a Beijing hospital. One hundred sixty-one patients died after surgery.
Each step up in peak lactate raised the odds of death by roughly a quarter to a third in adjusted and unadjusted analyses. The pattern held across surgery types and ran stronger in patients with higher anesthesia risk grades. Flexible curve modeling traced the dose shape without forcing it straight. Secondary outcomes covered hospital stay, intensive care time, and ventilation length. The authors propose the peak value as a cheap, early warning already hiding in the record.
