Difficult Intubation

This observational study aims to compare the predictive performance of the Modified El-Ganzouri Risk Index (MEGRI) incorporating anthropometric ratios with the original El-Ganzouri Risk Index (EGRI) for predicting difficult intubation in obese adult patients undergoing elective general anesthesia.

This prospective observational study aims to evaluate the relationship between preoperative ultrasonographic airway measurements and the Video-Intubation Difficulty Assessment Classification (VIDIAC) score in adult patients undergoing endotracheal intubation under general anesthesia. The study will investigate whether airway ultrasound parameters can predict difficult videolaryngoscopic intubation and assess their association with the Cormack-Lehane classification, intubation time, and other airway management outcomes.

This prospective observational study aims to evaluate the relationship between preoperative ultrasonographic airway measurements and the Pediatric Difficult Airway Classification (PeDiAC) score in pediatric patients undergoing general anesthesia. The study will assess whether ultrasound-derived airway parameters are associated with difficult airway characteristics and PeDiAC scores.

Cleft lip and palate surgeries present unique anesthetic challenges due to shared airway access with the surgical field, frequent anatomical abnormalities, and a predominantly infant and toddler population. These factors substantially increase the risk of perioperative respiratory adverse events (PRAEs), including laryngospasm, bronchospasm, desaturation, post-extubation stridor, and unanticipated re-intubation. This prospective single-center observational cohort study aims to determine the true incidence of PRAEs in pediatric patients undergoing elective cleft lip and/or palate repair under general anesthesia, and to identify independent predictive risk factors using standardized airway assessment tools including the Han Mask Ventilation Score and the Intubation Difficulty Score (IDS). No interventions beyond routine clinical practice will be applied. All airway management decisions will remain at the discretion of the attending anesthesiologist.

The aim of this project is to develop a computer algorithm that can accurately predict how easy or difficult it is to intubate a patient based upon digital photographs from three different perspectives. Such an application can provide a consistent, quantitative measure of intubation difficulty by analyzing facial features in captured photographs - features which have previously been shown to correlate with how easy or how hard it would be to perform the intubation procedure. This is in contrast to established subjective protocols that also serve to predict intubation difficulty, albeit with lower accuracy. A digital application has the potential to decrease potential complications related to intubation difficulty and increase patient safety.

A difficult airway is a clinical condition that occurs when one or more of the components of difficult mask ventilation, difficult laryngoscopy, difficult endotracheal intubation, difficult supraglottic airway device (SGA) placement, and inability to intubate-oxygenate are present. Data concerning incidence of difficult airway in patients undergoing cardiovascular surgery is controversial. Unwanted hemodynamic changes that may occur in patients undergoing cardiovascular surgery, combined with hemodynamic changes caused by underlying cardiac pathologies, may also lead to a physiologically difficult airway situation. Since all these interactions, combined with the hemodynamic changes caused by difficult airway interventions, may lead to catastrophic outcomes, it is vital to predict difficult airway in this patient population.

This is a prospective observational study.The purpose of this study is to predict difficult intubation with ultrasonographic evaluation combined with preoperative physical examination in patients diagnosed with acromegaly and planned for pituitary surgery.

Difficult airway management remains the leading cause of anaesthesia-related morbidity and mortality. Obstructive sleep apnea syndrome (OSAS) is a warning sign of difficult airway management. Polysomnography is the gold standard for diagnosis of this syndrome, but the STOP-BANG questionnaire is the preferred screening test. In this study, we wanted to find an answer to the question How successful is the STOP-BANG questionnaire in screening for obstructive sleep apnea syndrome (OSAS) in predicting OSAS, difficult mask and difficult intubation in patients undergoing thoracic surgery?
