Application of SHFJV for surgical procedures

Area of Science:

• Anesthesiology
• Otolaryngology
• Respiratory Medicine

Background:

• Traditional laryngeal surgery ventilation often requires endotracheal intubation, posing risks.
• Managing ventilation in patients with laryngeal stenosis or comorbidities presents unique challenges.

Purpose of the Study:

• To evaluate the efficacy and safety of supra-glottic jet ventilation (SHFJV) combined with a jet laryngoscope for laryngeal surgery.
• To explore the applicability of SHFJV in diverse patient populations and specific surgical scenarios.

Main Methods:

• Utilized SHFJV in conjunction with a jet laryngoscope for airway management during laryngeal procedures.
• Applied the technique in patients with pulmonary/cardiac disease, obesity, and laryngeal stenosis.
• Assessed ventilation safety, laser compatibility, and suitability for tracheobronchial stent insertion.

Main Results:

• SHFJV successfully facilitated ventilation without endotracheal tubes or catheters.
• The technique proved safe for patients with comorbidities and those with laryngeal stenosis, preventing barotrauma.
• Laser use was unhindered, and SHFJV was suitable for stent insertion.
• Ventilation efficacy was dependent on glottis visualization; transtracheal ventilation was preferred otherwise.

Conclusions:

• SHFJV with a jet laryngoscope offers a viable, safe alternative for laryngeal surgery ventilation, especially in challenging cases.
• This method enhances surgical safety by eliminating intubation risks and enabling flexible laser use.
• Transtracheal high-frequency ventilation remains the alternative when glottic visualization is compromised.
