High frequency jet-ventilation anaesthesia in patients with laryngeal pathology.
Keywords:High-frequency jet ventilation, suspension microlaryngoscopy, glottic space
Airway management in laryngeal surgeries is a challenge for an anesthesiologist due to sharing of airway with a surgeon. The airway is often compromised with potential for perioperative worsening. Introduction of high-frequency jet ventilation (HFJV) in 1970 offered a new modality to secure airway in the laryngology procedures, excluding the disadvantages of classic tracheal intubation. HFJV is characterized by delivery of small tidal volumes (1–2 ml/kg) from a high-pressure jet at supraphysiological frequencies (1–10 Hz) followed by passive expiration. At ENT clinic of “T.Moșneaga” hospital HFJV are used for several years. Applied via supraglottic aproach, HFJV is first choice in patients with severe laryngeal obstruction, lesions of posterior glottic regions, a lot of pacients being suffering of laryngeal papillomatosis. This method can be safely used in microlaryngeal surgery, excluding a lot of serious intraoperative complications, esspecially combustions of conventional endotracheal tubes. Till now, there are not reported complications in our local practice of HFJV
