Filter by:The primary purpose of this prospective observational study was to compare these tests used to predict difficult intubation in patients undergoing thyroid surgery. Secondarily; By comparing these tests, we aim to find the test that best predicts difficult intubation and to determine the incidence of difficult intubation in patients who will undergo thyroid surgery.
Video laryngoscope has become recommended option during difficult intubation. Guidelines of ASA at 2013 had suggested using video laryngoscope after failure intubation of direct laryngoscope. Varieties of video laryngoscope had been invented with different curves. We call the one which has the same curve of Macintosh laryngoscope as conventional video laryngoscope in this study. Mostly, the way of using conventional video laryngoscope is suggested as Macintosh method. However, with the front positioning camera, Miller method can theoretically improve the glottic opening. We intend to discuss whether using Miller approach with conventional video laryngoscope can improve glottic opening or not.
the aim of this work is to study how this technique will make nasal fiberoptic intubation easier and faster than the usual classic technique
The intubating Laryngeal Tube Suction-Disposable is a new version of the Laryngeal Tube-Suction. It has a ventilator channel with a 13.5mm internal diameter, which enables the passage of an Endotracheal Tube with fiberoptic guidance. This study was designed to assess the Time fiberoptic endotracheal intubation using iLTS-D, in comparison with the and Ambu® AuraGain™ in adult patients.
Prolonged mechanical ventilation patients rely on medical expenses per year had increased by nearly 20 billion in 15 years, so it is worthwhile to explore how to improve the respiratory function and even their quality of life of patients in Respiratory care wards (RCWs). This study used repeated experimental measurements and purpose sampling, and the investigators invited patients in respiratory care ward in northern Taiwan. They were randomly assigned to the experimental group and the control group. The experimental group was given 45 degree Semi-sitting 2 hrs and upper-limb exercise training 10 mins once a day. There were 29 prolonged mechanical ventilation (PMV) patients in the experimental group and 26 in the control group. Our conclusions showed that PMV patients can significantly improve the maximum inspiratory pressure (MIP) in the post-test while performed a 45-degree semi-sitting position with upper limb training for 4 weeks. The minute ventilation (MV) has a trend of increasing month by month in the experimental group, but it is necessary to consider whether it is due to the improvement of lung function or just cause of the increased oxygen consumption and accelerated respiratory rate, so it can not be inferred to improvement of the patient's condition or lung function.
Recognition of difficult airway is purported to be the most important factor in successful management of difficult airway. The incidence of difficult airway in pediatrics is much less than in adults; however, airway related complications can lead to hypoxic brain damage or even death especially in younger age groups as neonates and infants.The aim of this work is to evaluate the feasibility and accuracy of ultrasound measurements (hyomental distances, tongue measurements, and anterior neck soft tissue thickness at the level of hyoid bone, thyrohyoid membrane, and thyroid cartilage) in predicting difficult laryngoscopy and difficult mask ventilation in pediatric patients undergoing elective surgery under general anesthesia.
LMA insertion provide an intact airway for many surgeries during general anesthesia . LMA insertion technique was defined when it was first produced by Archie Brain . Accordingly, it is recommended to advance the device to the level where resistance is felt blindly. However, placing LMA may not always be smooth and uncomplicated. Thus, gas leaks may occur and intragastric pressure increase may occur due to gastric insufflation. To overcome these difficulties, the placement of the LMA under direct vision using a laryngoscope has been described in several studies . Previous studies have shown that the reliability of the laryngeal mask can be demonstrated by the oropharyngeal cuff leak test . In addition, the classification of the image of the laryngeal structures mediated by fiberoptic imaging and vocal cords from the LMA gives us information about the availability of effective positive pressure ventilation.
As a result of anatomical and physiological changes in obese patients, airway management can be challenging. Ultrasound measurement of neck anterior soft tissues combined with recommended predictive tests may increase the ability to predict the difficult airway. In this study we planned to evaluate the measurement of neck anterior soft tissues by ultrasound in obese patients before anesthesia induction to anticipate difficult mask ventilation, difficult laryngoscopy, and intubation.
This study was designed to assess the success of indirect laryngoscopy and ultrasonographic measurements in the prediction of difficult airway. All patients were examined by indirect laryngoscopy and ultrasonography preoperatively and the predictive values for difficult airway of these methods were compared.
Ultrasound has become an essential tool for the daily work of any doctor, but in certain specialties such as Anaesthesiology, its use has greatly increased the safety offered to patients throughout the perioperative period, either to perform nerve blocks, for vascular access, intraoperative hemodynamic management or any other use that allows increasing quality of care. The management of the upper airway and the diagnosis of pathological conditions are essential skills for any doctor especially for Anaesthesiologist, ER physician, or Intensive Care physician. Because an inadequate airway management continues to be an important contributor to patient mortality and morbidity, any tool that can improve it should be considered as an addition to conventional clinical evaluation. Unfortunately, most of the clinical parameters that should allow us to assess a potential difficult airway, do not always lead us to an adequate prediction, that is why US(Ultrasound) is use as an emerging tool in many fields, is also gathering strength in this search for a definitive predictor parameter. Ultrasound has many obvious advantages (safe,fast, repeatable, portable, widely available and gives dynamic images in real time). Sonographic studies are operator-dependent and although the identification of basic structures could be acquired with only a few hours of training, but more complex studies require a learning curve of months or even years. The high frequency linear probe (5-14 MHz) is probably the most suitable for the airway because images are of superficial structures (within 0-5 cm below the skin surface). The growing academic interest in the use of US to look for predictors of difficult airway is centred mainly on measurements at the level of pretracheal tissues. But the greatest limitation of these studies is the disparity of the fat distribution that exists between different ethnic groups and and sexes, and the lack of standardization method in patient´s intubation conditions. So, the investigator propose to assess different ultrasound windows at the level of pretracheal tissues such as independent predictors of Difficult Airway.
