AI-Based Prediction of Difficult Airway in Bariatric Surgery (AI-Airway)

2026年6月18日 更新者:Muhammed Başpınar、Elazıg Fethi Sekin Sehir Hastanesi

Artificial Intelligence-Based Prediction of Difficult Airway in Bariatric Surgery: A Prospective Evaluation of Preoperative Airway Predictors

The aim of this prospective study is to evaluate the accuracy of artificial intelligence (AI) and machine learning algorithms in predicting difficult airways in patients undergoing bariatric surgery. Preoperative airway assessments, including the Upper Lip Bite Test (UBLT), Mallampati score, Body Mass Index (BMI), thyromental distance (TMD), and sternomental distance (SMD), will be recorded. The study investigates whether AI models can provide higher sensitivity and specificity in predicting difficult intubation compared to traditional clinical scoring systems in the obese patient population.

研究人群

The study population consists of adult obese patients (BMI ≥ 35 kg/m²) undergoing elective bariatric surgery under general anesthesia in a tertiary academic medical center. This population represents individuals at a higher baseline risk for difficult airway management and intubation.

描述

Inclusion Criteria:

  1. Adult patients aged 18 to 65 years.
  2. Scheduled for elective bariatric surgery under general anesthesia.
  3. Body Mass Index (BMI) ≥ 35 kg/m².
  4. Consenting to participate in the study.

Exclusion Criteria:

  1. Patients with known upper airway anatomical deformities, head and neck tumors, or a history of head/neck radiotherapy.
  2. History of maxillofacial, airway, or cervical spine surgery.
  3. Emergency surgeries.
  4. Patients requiring planned awake fiberoptic intubation based on obvious preoperative clinical indicators.

主要结果指标

结果测量
措施说明
大体时间
Diagnostic Accuracy of the Artificial Intelligence Model in Predicting Difficult Intubation
大体时间:Intraoperative (assessed during the primary intubation attempt)
The predictive performance of the AI model will be evaluated by comparing its preoperative difficult airway prediction against the actual intraoperative direct laryngoscopy view. The intraoperative view is graded using the Cormack-Lehane classification system. Grades 3 and 4 are clinically defined as difficult intubation, while Grades 1 and 2 are defined as easy intubation. The primary metric of diagnostic accuracy will be the Area Under the Receiver Operating Characteristic (AUC-ROC) curve.
Intraoperative (assessed during the primary intubation attempt)
