Perioperative predictors of critical care admission following emergency surgical procedures: a comprehensive evaluation of anesthesia management.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundEmergency surgical procedures carry substantial risk, with increased morbidity, mortality, and unplanned intensive care unit (ICU) admissions. Identifying perioperative factors associated with postoperative ICU requirement is essential for improving outcomes and optimizing resource allocation. This study evaluated anesthesia management practices in a large emergency surgery cohort and investigated independent predictors of postoperative ICU admission.
methodsThis retrospective cohort study included 1,984 patients who underwent emergency surgical procedures at a tertiary center between 2022 and 2023. Demographics, trauma status, ASA classification, airway management, anesthetic technique, hemodynamic support, transfusion, and postoperative analgesia were recorded. The primary endpoint was postoperative ICU admission.
resultsThe ICU admission rate was 12.1%. ICU-admitted patients were older (57.5 ± 19.1 vs. 36.9 ± 15.2 years, p < 0.001) and more frequently presented with trauma (30.8% vs. 16.0%, p < 0.001). Higher ASA scores, vasopressor or inotrope use (19.9% vs. 0.3%, p < 0.001), and transfusion (32.1% vs. 3.6%, p < 0.001) were strongly associated with ICU need. Multivariate analysis identified age (OR:1.027), trauma (OR:1.606), ASA score (OR:4.376), vasopressor or inotrope use (OR:24.408), and transfusion (OR:4.952) as independently associated factors (all p < 0.05). Specialties showed notable variation in anesthetic technique and postoperative practices.
conclusionsPostoperative ICU requirement in emergency surgery is associated with advanced age, trauma, elevated ASA status, hemodynamic instability, and transfusion. Recognizing these predictors may help inform risk stratification, perioperative planning, and ICU resource utilization. Standardizing anesthesia protocols and strengthening hemodynamic optimization strategies may help inform perioperative risk stratification and ICU resource allocation.
