Stylet sheath formation is a common feature among phytophagous hemipterans. These sheaths are considered essential to promote a successful feeding event. Stylet sheath compositions are largely unknown and their mode of solidification remains to be elucidated. This report demonstrates the formation and solidification of in āere (in air) produced stylet sheaths by six hemipteran families: Diaphor...

CONCLUSION The study shows that there are differences in the measurement of the action potentials with and without the stylet in the Nucleus Freedom Contour Advance that are higher in the apex than in the base of the cochlea. OBJECTIVES To determine if there are differences in the intraoperative impedances and in the neural response telemetry threshold values in the Nucleus Freedom Contour Ad...

Gracilacus wuae n. sp. from soil associated with cow parsnip in Ontario, Canada is described and illustrated. Morphologically, females have a long stylet ranging from 80 to 93 µm long, the lip region not offset from the body contour, without lateral lips but with large and flat submedian lobes, the mouth opening slit-like elongated laterally and surrounded by lateral flaps, the excretory pore i...

BACKGROUND Stylets are the most frequently used devices for tracheal intubation, but can be a source of postoperative pharyngeal pain or hoarseness. In this study, we evaluated extraction forces between polyvinyl chloride (PVC) and stannum (Sn) stylets with various lubricants. FINDINGS Using a manikin, we compared extraction forces between PVC and Sn stylets under four different conditions: w...

In anesthesia practice, stylet is used as an aid in difficult tracheal (ET) intubation. Disposable plastic covered or plastic bougies are recommended but in developing countries, the metal stylets are still in use. Shearing of part of stylet has been reported in past but all incidents were detected immediately. We report a case of tracheal tube blockade due to a broken stylet tip which initiall...

Background: Insertion of a nasogastric tube in an anesthetized intubated patient may be difficult. A is prone to coil and kink during insertion. The authors hypothesized that gastric biopsy forceps could used as flexible stylet-assisted It can improve the first-attempt success rate over conventional blind technique insertion patient. Materials Methods: Eighty adult patients who required intraop...

OBJECTIVES/HYPOTHESIS Vocal fold injury is a well-know complication of intubation, with rates reported as high as 69%. Laryngology textbooks recommend the use of a small endotracheal tube (ETT) to help avoid these complications and optimize visualization. Case reports have suggested that the rigid stylet can lead to laryngeal injury. Given the additional risks, intubation without the stylet is ...

OBJECTIVE Endotracheal intubation of newborn infants is a common and potentially lifesaving procedure but a skill that trainees find difficult. Despite widespread use, no data are available on whether the use of a stylet (introducer) improves success rates. We aimed to determine whether pediatric trainees were more successful at neonatal orotracheal intubation when a stylet was used. METHODS ...

OBJECTIVES To evaluate Parker Flex-It stylet as an alternative to GlideRite Rigid stylet to aid tracheal intubation with the Glidescope.  METHODS This prospective randomized trial was conducted at King Abdulaziz University Hospital, College of Medicine, King Saud University, Riyadh, Saudi Arabia between May and December 2014. Sixty American Society of Anesthesiologists I-II patients were rand...

BACKGROUND AND OBJECTIVES This study was conducted to investigate the effects of reinsertion of the stylet after a spinal anesthesia procedure on the Post Dural Puncture Headache (PDPH). METHODS We have enrolled into this study 630 patients who were undergoing elective operations with spinal anesthesia and randomized them to Group A (stylet replacement before needle removal) and Group B (need...
