OBJECTIVE Robotic cochlear implant electrode array insertion offers substantial potential advantages, namely repeatability and minimization of insertion forces, leading to decreased intracochlear trauma. Using such a robotic insertion tool, we sought to analyze force profiles during deployment of stylet-containing electrode arrays using either traditional insertion, in which the stylet is withd...

PURPOSE To compare the ease of tracheal intubation facilitated by the gum elastic bougie or the malleable stylet while applying cricoid pressure. METHODS Sixty American Society of Anesthesiologists I-III adult patients undergoing elective surgeries participated in this study. After induction of anesthesia with 2.5 mg x kg(-1) propofol and vecuronium 0.1 mg x kg(-1), the laryngeal view was ass...

Two new species of the "Aequales" of genus Gieysztoria were collected and described from an artificial lake on the Shenzhen University campus. Gieysztoria bimaculata n. sp., is distinguished based on two groups clavate pigmentations dorsally between the pharynx and intestine, and has a sclerotic stylet comprising a proximal girdle with 40-46 distal dagger-shape spines, thus has the maximum numb...

Paratylenchus shenzhenensis n. sp. was collected from the rhizosphere soil of Anthurium andraeanum in Shenzhen, Guangdong Province, China. The new species is characterized by having a female with a small body (249-302 μm), well developed stylet (17-21 μm), rounded head with four submedian lobes and lip-region with a slight depression at the oral area, small post-vulval uterine sac with a few ve...

The feeding apparatus of Pratylenchus penetrans (Cobb) Chitwood and Oteifa was studied by means of the electron microscope. The stomatostylet is composed of tooth, shaft, and basal knobs. The tooth and shaft are closely interlocked. The tooth forms the outer covering and the inner lining of the anterior half of the stylet, whereas the shaft extends from the basal knobs to the level of the style...

Background. Intubation is the optimal method for opening the airway and effective ventilation of the patient. However, there are occasional problems with intubation, especially in patients with injuries under pre-hospital conditions. Therefore, it is important to identify devices, e.g., videolaryngoscopes or guides, which may facilitate and shorten the procedure. This study addresses the use of...

With great interest, we read the recent article by Sheta et al1 comparing performance of the Parker Flex-It stylet and GlideRite Rigid stylet for orotracheal intubation by Glidescope videolaryngoscope in patients with normal airways. They showed that the 2 stylets were equally effective for intubation when used by experienced operators, but the Parker Flex-It stylet was easier and less traumati...

BACKGROUND The McGrath videolaryngoscope (VL) provides excellent laryngoscopic views, but directing an endotracheal tube can be difficult, and thus the routine use of a stylet is recommended. The goal of this study is to determine the appropriate angle (60° vs 90°) of the stylet when using the McGrath VL by comparing the time to intubation (TTI). METHODS One hundred and forty patients aged 19...

Intubation stylets are still being used in many medical centers for difficult intubations. Although very rare, it may break inside the trachea during endotracheal intubation despite routine pre-assessments by anesthesiologists and may surprisingly move deep into the tracheobronchial tree. In this case report, we describe a rare complication after stylet or guide-wire intubation in a patient in ...
