Filter by: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.
In this prospective, randomized, cross-over study, investigators aimed to compare the first pass successes of inexperienced doctors with Macintosh laryngoscopy and endotracheal tube introducer on a manikin with continuous chest compression in the ambulance simulation in the pre-hospital process.
In the presented study, our aim was to compare intubation conditions regarding the modified Cormack & Lehane score (CL) between the D-Blade® in indirect laryngoscopy or Macintosh blade in direct and indirect laryngoscopy with C-MAC PM® in a simulated setting of a difficult airway in human subjects.
Difficult intubation is considered one of the most important obstacle increasing mortality in anesthesiology. Airway assessment tests are proceeded to overcome these difficulties in the pre-anesthetic evaluation. In this study, the Simplified Predictive Intubation Difficulty Score (SPIDS) and Thyromental Height Measurement (TMH) were chosen as primary methods to predict difficult intubation. The ear-nose-throat (ENT) and Plastic Surgery patients were planned to enroll this study to assess the effectiveness of these tests in predicting difficult intubation in Maltepe University Hospital and Sisli Hamidiye Etfal Governmental Hospital. The SPIDS of volunteers will be calculated according to their previous knowledge of difficult intubation, airway pathologies, head and neck movements, mouth opening, modified Mallampati test and thyromental distance. TMH value will be measured with ASIMETO depth device. Finally, the SPIDS and TMH values will be statistically compared to predict difficult intubation which is determined with difficult intubation score (IDS).
