Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this observational study is to identify the risk factors and build the early warning system of sepsis and septic shock after major abdominal surgery based on artificial intelligence. The main questions it aims to answer are:

What are the high risk factors of postoperative sepsis? Which factors can accelerate the progression of sepsis? Researchers will collect perioperative characteristics to construct predictive models of postoperative sepsis in a retrospective abdominal surgical population based on artificial intelligence, and the accuracy of the models were tested in an external dataset.

Exposure to major abdominal surgery

This study is a retrospective cohort study. The 'exposure' situation is based on historical records and observation, and no active intervention has been conducted on the study subjects to change their exposure status.

Intervention Type PROCEDURE

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Patients undergoing major abdominal surgery.
2. The surgeon performing the operation has extensive experience in specialized surgeries such as upper gastrointestinal, hepatobiliary and pancreatic, colorectal, gynecological, and urological surgeries, having completed at least 50 corresponding specialized surgical cases.
3. The anesthesiologist performing the operation has more than 5 years of clinical experience.
4. All surgical patients receive general anesthesia.

Exclusion Criteria

1\. Pregnancy-related surgeries (cesarean section, abortion surgery). 2. Patients with known preoperative infection or suspected infection. 3. Severely malnourished patients (BMI reference values are 17 kg/m² for patients \< 70 years old and 17.8 kg/m² for patients \> 70 years old).

4\. Patients who have previously undergone abdominal surgery. 5. Patients without sufficient data, including demographic variables (such as age, gender), surgical details (surgery duration, surgical grade, anesthesia grade, anesthesia duration), and hospitalization details (such as ICU stay, in-hospital mortality).
