Filter by:Diseases of the larynx and trachea are a heterogenous group of disorders. Witch may include congenital anatomical disorders, neoplastic changes, vocal cord paralysis of varied aetiology or narrowing of the larynx associated with long-term intubation. The multitude of disorders of these organs necessitates the continuing search for diagnostic methods which will not only provide answers to clinical questions but will also be safe and with the least level of interference with the wellbeing of the patient, which is of particular importance in the neonate. In recent decades only a few studies have been reported which described the ultrasound anatomy of the larynx prior to and following intubation or that of the mobility of the vocal cords. To date, no standards have been published concerning the size of the structures of the larynx and trachea or the mobility of the vocal cords on ultrasound examination in the neonate. Additionally, there are no recommendations which include ultrasound examination as a reliable component of the diagnosis of congenital disorders of the larynx or other diseases of this organ. Ultrasound is a non-invasive, repeatable and safe diagnostic method, which has recently, thanks the development of technology, provided for the very accurate imaging of even small structures, as well as their assessment on dynamic examination. Furthermore, the easy availability of this examination may in the future contribute to the early diagnosis of diseases of the larynx and trachea without the need to prolong neonatal hospitalization or anaesthesia. In addition, the use of neural networks to analyse the ultrasound images obtained will provide for the development of algorithms which could become an irreplaceable tool, not only in the diagnosis of the disorders described, but also in predicating disorders affecting their further development or functional disorders in infancy.
Ventilation through the small endotracheal tube is not an uncommon situation. The indications for it differ from elective upper airway surgery to emergency ventilation through needle cricothyrotomy. Conventionally, ventilation through small endotracheal tubes has been challenging by jet ventilation with subsequent risk of barotrauma and inadequate gas exchange. Expiration during jet ventilation occurs passively.
Airway securing through the placement of an endotracheal tube continues to be the definitive and the global standard management. The successful first attempt is aimed to avoid the consequences of multiple intubation trials as bleeding, tissue swelling, and airway contamination from gastric content that led to considerable morbidity and mortality. Visualization of the larynx and the glottic opening is the key to first-pass success requiring long-term training and availability of specific equipment concerned to that. For confirmation of the position endotracheal tube or its displacement, various clinical and equipment aids to that which are not valid or limited in different scenarios. Video laryngoscopes (VL) have been proposed to improve laryngeal visualization, hence a higher first-pass success rate accomplished. Despite that, there are limitations of video laryngoscope use in different circumstances that requiring adding of other aids to facilitate endotracheal intubation. x
Surgical pleth index (SPI) has been widely investigated in assessing the nociceptive level, and tracheal intubation is a noxious stimulus during the induction of anesthesia. This study aims to evaluate the ability of SPI to predict hemodynamic reactivity after tracheal intubation, and find the target value of SPI to guide the optimal timing for tracheal intubation.
