Comparison of Cormack Lehane Grading System and Intubation Difficulty Score in Patients Intubated by D-Blade Video...

Area of Science:

• Anesthesiology
• Medical Devices
• Airway Management

Background:

• Videolaryngoscopy offers indirect glottic visualization for airway management.
• The D-blade is a novel device designed to enhance indirectoscopic glottic view.
• Direct laryngoscopy with the Macintosh blade is considered the gold standard.

Purpose of the Study:

• To compare the efficiency of the D-blade videolaryngoscope against the direct Macintosh laryngoscope.
• To evaluate the D-blade's effectiveness in routine airway management procedures.

Main Methods:

• A randomized study involving 52 adult patients undergoing elective surgery under general anesthesia.
• Patients were assigned to either the D-blade video group or the direct Macintosh laryngoscope group.
• Evaluations included Cormack-Lehane (C-L) grading for glottic view, intubation duration, intubation difficulty score (IDS), and hemodynamic parameters.

Main Results:

• No statistically significant differences were observed between the D-blade and Macintosh groups in terms of intubation time, ease of endotracheal tube insertion, C-L grade, or IDS.
• The D-blade exhibited similar, favorable characteristics compared to the direct Macintosh laryngoscope.

Conclusions:

• The D-blade videolaryngoscope is a useful tool for airway management.
• The D-blade demonstrates comparable efficacy to the Macintosh laryngoscope and is suitable for routine anesthesiologist use.
