Can the "Face Index"; an Anthropometric Measurement, Predict Difficult Laryngoscopy and Intubation?

Patient safety is the cornerstone of anesthetic practice, and maintaining adequate respiration represents its most critical initial step. In situations where spontaneous breathing cannot be sustained-such as during general anesthesia-the airway must be mechanically secured. While simple face masks may be sufficient in some cases, endotracheal intubation remains the most reliable method for airway control in conditions associated with respiratory depression. Airway management may be challenging due to various patient-related anatomical factors, including facial and mandibular structure, obesity, limited mouth opening, facial hair, sunken cheeks, wide facial morphology, and a short or muscular neck. These challenges are collectively described as difficult ventilation and difficult intubation (cannot ventilate-cannot intubate), which may occur unexpectedly or be anticipated. A difficult airway is defined as difficulty encountered by a trained anesthesiologist in face mask ventilation, tracheal intubation, or both. Several predictors of difficult airway are widely accepted, such as thyromental and sternomental distances, neck circumference, Mallampati classification, upper lip bite test, mouth opening, and interincisor distance. Thorough preoperative airway evaluation is mandatory, as difficult mask ventilation and failed intubation remain major contributors to anesthesia-related morbidity and mortality. Although numerous studies have examined these predictors, research focusing on facial morphology and anthropometric indices-particularly the face index-is extremely limited. Facial morphology varies considerably among individuals and can be evaluated anthropometrically using simple, noninvasive tools such as a digital caliper. Anthropometric analysis is commonly applied in forensic medicine and reconstructive surgery but has rarely been incorporated into airway assessment. This study aims to introduce face index analysis as a novel predictor of difficult airway alongside conventional methods. By evaluating measurements such as trichion-gnathion distance, total facial index, upper facial index, and nasal index, the study investigates whether airway difficulty can be predicted using a single index value. All measurements are standard, noninvasive, and routinely performed during preoperative assessment.

MAsk VEntilation With Paratracheal Pressure In Children. Para Tracheal Compression to Prevent Gastric Insufflation in Children

The use of cricoid pressure to prevent gastric aspiration or regurgitation in case of "full stomach" situation or emergency is still controversial in the adult population. Moreover this maneuver is no more recommended in children by some European pediatric anesthesia societies, because of a lack of evidence of its protective effect against gastric aspiration and its possible adverse effects. A new approach to occlude effectively the esophageal lumen has been recently described in adults and has shown its effectiveness to prevent gastric insufflation. But this maneuver has so far not been evaluated in the pediatric population and could be an alternative to prevent gastro-esophageal regurgitation and pulmonary aspiration in children

Video Laryngeal Mask vs. Endotracheal Tube in Septoplasty

This randomized controlled trial compares a video laryngeal mask airway (VLMA) and an endotracheal tube (ETT) in adult patients undergoing elective septoplasty. The primary objective is to see which device more effectively prevents surgical blood contamination in the glottic and subglottic regions. The study also assesses perioperative hemodynamic stability, ventilation parameters, and postoperative recovery factors such as sore throat, hoarseness, and overall patient comfort. The findings aim to help determine the optimal airway device choice for nasal surgeries.

Ability to Maintain Saturation Levels Without Oxygen Supplementation as a Extubation Criteria Without TOF Monitoring Equipment

Patients undergoing general anesthesia will have an endotracheal tube inserted. Adequate muscle strength recovery in the recovery room is crucial to ensure before extubation. One of the criteria we use to determine the recovery of muscle strength post-use of muscle relaxants in conditions without specific monitoring devices is the ability to maintain body oxygen levels without oxygen assistance for 3 minutes. This study aims to determine the muscle strength value in the recovery room using extubation strategies without muscle strength monitoring compared to extubation strategies with muscle strength monitoring.
