Airway assessment using ultrasonography can provide an additional information in identifying difficult intubation in OSA patients. The main purpose of this study is to find the correlation of the ultrasound parameters and the Cormack Lehane Score (CL Score) as well as to identify the cut-off point of the ultrasound parameters that would differentiate between the easy and difficult intubation.
The aim of this study to assess and compare between methods of prediction of difficult airway including Mallmpati score , thyromental distance and us measured distance from skin to epiglottis(DES) t the level of thyrohyoid membrane in adult patients requiring endotracheal intubation for an elective surgical procedure.
Adult patients requiring endotracheal intubation divided into three groups; standard Airtraq, Nasotracheal Airtraq + styletted endotracheal tube and Airtraq + fiberoptic combination groups.
Along with the technological advances in medicine, videolaryngoscope is the most commonly preferred technique for intubation of expected difficult airway management such as morbidly obese patients. In this prospective controlled clinical study, the purpose is to compare C-MAC videolaryngoscope and McGrath MAC videolaryngoscope in respect to duration of intubation, haemodynamic response, and complications related intubation of morbidly obese patients undergoing bariatric surgery.
Background: Obtaining airway security holds the utmost importance in anesthesia. Specific predictive tests or findings for difficult airway are not defined for various pediatric age groups. Anthropometric measurements are defined parallel to percentile curves in different age groups. Aim: The aim of this study is to find out the value of body mass index and anthropometric measurements in prediction of difficult laryngoscopy in children by comparing to direct laryngoscopic evaluation of Cormack-Lehane test. Methods: Following institutional ethics committee approval and informed consent of parents of 108 patients (ages 0-3years), undergoing elective surgery were included in this study. Weight, height, body mass index and head circumference of the patients were measured and percentiles were recorded, prior to induction. Following standard anesthesia induction with thiopental all patients received 0,6 mg.kg-1 rocuronium intravenously. After sufficient time for neuromuscular relaxation laryngoscopy performed and Cormack-Lehane scores recorded. All recorded parameters were compared with Cormack-Lehane scores.
Evaluation of airway markers of patients who have undergone obesity surgery.
In the current study researchers aim to evaluate the rate of the complication due to airway management (during intubation or placement of supraglottic airway devices)
Background: Unpredictable laryngoscopic difficulty remains a dramatic challenge for anaesthesiologists. Ultrasound (US) based airway assessment has been recently proposed as a useful tool in adjunct to clinical methods, but to date few studies are available about the potential role of ultrasound in difficult airway evaluation. The aim of this study is to determine the correlation between the sonographic measurements of anterior cervical soft tissues's thickness and Cormack-Lehane grade view at direct laryngoscopy in patients with normal clinical screening tests. Design: Prospective, single blinded, observational study. Number of patients: 300 adult patients Methods: All patients are assessed before surgery to evaluate clinical evidence of difficult airways. Simultaneous ultrasound measures of the anterior cervical soft tissues are performed. At induction of anaesthesia the laryngoscopic view is graded by a different anaesthetist, blinded to the ultrasound assessments. Statistical analysis: Receiver operating characteristic curves (ROC) are used to determine the "difficulty prediction capability" of each sonographic measurement and to assess the optimal cut-off scores To allow for comparisons between "restricted-difficult" airway and "easy" airway groups, a two-sided Student's t-test and Fisher's exact test is employed as appropriate. The results will be averaged (mean ± standard deviation SD) for each parameter for continuous data. Values of p < 0.05 are considered as statistically significant.
When difficult airway/intubation occurs in the OR the anesthesiologist needs rescue techniques and equipment. The algorithms about management of the difficult airway don't provide adequate data. In current study researchers aim to determine most preferred rescue techniques and success rate of the chosen technique.
