The seeing stylet: a new device for tracheal intubation.

Area of Science:

• Anesthesiology
• Medical Devices
• Airway Management

Background:

• Tracheal intubation is a critical procedure in anesthesia.
• Direct visualization during intubation can improve success rates and patient safety.
• Existing devices may have limitations in terms of cost, reusability, or visualization quality.

Purpose of the Study:

• To evaluate the efficacy and safety of the Shikani Seeing Stylet for tracheal intubation.
• To assess the impact of the Shikani Seeing Stylet on patient vital signs during intubation.
• To determine the success rate and time required for intubation using the Shikani Seeing Stylet.

Main Methods:

• A prospective study involving 20 adult patients (ASA I-II) undergoing elective surgery requiring tracheal intubation.
• The Shikani Seeing Stylet, a high-resolution endoscope with a malleable sheath, was used for direct vision intubation.
• Hemodynamic parameters (heart rate, blood pressure) and respiratory parameters (oxygen saturation, end-tidal carbon dioxide) were monitored at defined time points.

Main Results:

• Successful tracheal intubation was achieved in all 20 patients using the Shikani Seeing Stylet.
• The majority of patients (11/20) were intubated on the first attempt, with a mean procedure time of 8.65 seconds.
• Patient vital signs, including heart rate, blood pressure, oxygen saturation, and end-tidal carbon dioxide, remained stable throughout the intubation process.

Conclusions:

• The Shikani Seeing Stylet is an effective and safe device for direct vision tracheal intubation.
• The device appears to be a valuable adjunct for airway management, potentially reducing intubation difficulty and time.
• Further studies are warranted to confirm these preliminary findings in a larger patient population.
