Filter by:Tracheal intubation in the intensive care unit (ICU) is associated with high incidence of difficult intubation and complications. Videolaryngoscopes (VLs) devices have been proposed to improve airway management, and the use of VLs are recommended as first-line or after a first-attempt failure using direct laryngoscopy in ICU airway management algorithms. Although until relatively few years ago there were doubts about whether videolaryngoscopes had advantages over direct laryngoscopy for endotracheal intubation (ETI) in critically ill patients, two recent studies (DEVICE (1), INTUBATE (2)), and a Cochrane review (3) have confirmed that videolaryn should be used?, and what is the best blade? . There are two types of blades commonly used with videolaryngoscopes: the "Macintosh" blade with a slight curvature, and hyperangulated blades. The "Macintosh" blades have a lower angle of vision, but they have the advantage of being similar to the blades commonly used in direct laryngoscopy, making them easy to use for the person performing the ETI. Hyperangulated blades have a greater angle of vision, improving glottic visualization, especially in patients with an anterior glottis. However, the need to overcome this angulation could potentially hinder the passage of the endotracheal tube to the vocal cords. It is unknown if either blade has any advantage for intubating critically ill patients.
The study aims to compare the success and time of intubation through an intubating laryngeal mask vs. direct laryngoscopy in a manikin simulating a term infant. In addition, we will assess the operator's opinion on the procedure. This is an unblinded, randomized, controlled, crossover (AB/BA) pilot trial of intubation procedure through intubating laryngeal mask vs direct laryngoscopy in a manikin simulating a term newborn.
Endotracheal intubation is a frequent procedure in the operating room but optimal Macintosh blade size remains unknown to date.
Purpose: To compare the efficacy and safety of TCI tube core and ordinary tube core assisted tracheal intubation in simulating difficult airway under visual laryngoscope, and to provide reference for clinical application
Morbid obesity is a growing disease. Intubations of these patients mostly difficult. Video laryngoscopes have to be used during the intubation of these patients. The intubation of men is more complicated and difficult than obese women. There were no trials compared to the new video laryngoscopes in morbidly obese men. Patients will be divided into two groups; non-obese and klas 2-3 obese. Airtraq will be used for their intubation. The time for intubation will be the primary aim of this prospective randomized study. The insertion time, perioperative hemodynamic variables, and postoperative complications will also be recorded.
Cervical immobilization with manual in-line stabilization (MILS) is recommended to prevent further neurologic injury during intubation in patients with known or suspected cervical spine injuries. However, MILS is associated with increased rates of failed tracheal intubation using direct laryngoscopy, because the restriction of neck flexion and head extension may prevent adequate alignment of the oral, pharyngeal, and tracheal axes, hence adversely affecting laryngeal visualization during direct laryngoscopy. The GlideScope® (Verathon, Bothell, WA, USA) is a videolaryngoscope with an hyer-angulated blade (HA-VL), which is characterized by a sharper curvature than the Macintosh blade. The large curvature of the HA-VL allows seeing 'round the corner', which can provide indirect laryngeal visualization even with restricted neck movements . However, the HA-VL also prevents direct visualization of larynx, which make it difficult to guide the tracheal tube (TT) towards the glottis despite obtaining a good laryngeal view. Thus, the good view of the laryngeal inlet provided by videolaryngoscopes does not always lead to an easy or successful intubation. There are numerous reports in the literature of devices managing to achieve an improvement in view but still being unable to pass an TT to laryngeal inlet. Thus, the key to a successful tracheal intubation using HA-VL lies not in the laryngeal view obtained but in the ease of inserting the TT. Recent meta studies comparing alternative intubation devices with the standard Macintosh laryngoscope in subjects with cervical spine immobilization reported that GlideScope® was associated with improved glottis visualization but no statistically significant differences in intubation failure or time to intubation compared with direct laryngoscopy. The sniffing position recommended for direct laryngoscopy has been reported to interfere with successful tracheal intubation with HA-VL because flexion of the neck narrows the angle between the sternum and the chin, making it more difficult to insert the HA-VL blade into mouth. In contrast, placing the patient in a 'neutral' or 'back-up head-elevated (BUHE)' position was not associated with a higher incidence of difficult laryngoscope with HA-VL. Given that the 'BUHE' position, when compared with the regular supine position, extend the safe apnoea time during direct laryngoscopy, this position seems better suited for HA-VL than neutral position. However, there is currently insufficient evidence to recommend a specific patient position for the use of HA-VL. Previous studies using magnetic resonance imaging (MRI) suggests that head elevation until the external auditory meatus and sternal notch (AM-S) are in the horizonal plane leads to better anatomic alignment of the pharyngeal and laryngeal axes. Investigators therefore hypothesized that BUHE position (to align the AM-S in horizontal plane), compared with neutral position, would allow a relatively straight passage which makes it easier to guide the TT into the laryngeal inlet (facilitates insertion of TT into the laryngeal entrance) during HA-VL guided intubation. To compare the effect of the BUHE position and the neutral position on the ease of tracheal intubation using a HA-VL (GlideScope®), MILS was applied to patients without any known or suspected neck pathology as a way of simulating a difficult airway. The primary outcome was the tracheal intubation time with both positions. Secondary outcomes examined included rates of successful tracheal intubation and intubation success rate, number of intubation attempts, heart rate responses during intubation, and handling of the Glidesope VL after alignment of the EAM and sternal notch.
EcoID is a study designed as an adaptive controlled clinical trial with a first phase of superiority and a second phase of non-inferiority with change of control, of parallel groups, random assignment and blinding of investigators measuring outcome.
Airway management is extremely important for providing safe anesthesia. Endotracheal intubation, on the other hand, is the most important step in airway management, especially since it requires rapid and successful execution. Inadequate airway management; is associated with complications that require high-level care and cost, such as death, brain damage, increased need for intensive care, prolonged recovery period, and emergency tracheostomy. 15-25% of anesthesia-related deaths are associated with airway management. 17% of settled cases against anesthesiologists are composed of airway-related events (often difficult intubation, inadequate oxygenation/ventilation, and pulmonary aspiration). An important point in ensuring airway patency is preoperative evaluation. Difficulties arising from anatomical features can be revealed by careful evaluation of mouth opening, the structure of tongue and palate, thyromental distance (TMM), sternomental distance (SMM), mobility of cervical vertebrae, jaw occlusion, and necessary precautions can be taken. The most commonly used tests to determine the degree of difficulty of intubation are the modified Mallampati test, the thyromental distance, the upper lip bite test, the inter incisor space, and the sternomental distance. Recent studies are trying to confirm the sensitivity and specificity of existing tests. However, there is no test with 100% specificity and sensitivity in predicting difficult laryngoscopy and intubation.
Early detection of esophageal intubation, one of the most common complications while performing endotracheal intubation (ETI), is crucial to adequate airway management, especially among patients suspected of difficult intubation (DI). Detective approaches with ventilation require time, increase the risk of emesis and aspiration to patients, and increase the risk of particle aerosolization to health providers under the epidemic of aerosol-borne diseases. Our study will determine the effectiveness of real-time sonography assisted to direct visualization to detect esophageal intubation before ventilation among DI patients.
