Sponsor's own description

Objective: To estimate regional lung volume changes by electrical impedance tomography (EIT) during supra- and subglottic jet ventilation via the jet laryngoscope and LaserJet catheter for performing laryngotracheal surgery. Design: A monocentric, prospective, randomized study. Patients: Patients who require elective micro laryngo-tracheal surgery under jet ventilation. Interventions: Patients undergoing elective micro laryngeal surgery will be assigned to subglottic JV via the new LaserJet catheter and supraglottic JV via the jet laryngoscope vice versa. The sequence of JV modes will be randomized (subglottic followed by supraglottic or supraglottic followed by subglottic JV). Hemodynamic and ventilation parameters will be monitored. Arterial blood gas samples will be drawn and the regional ventilation distribution assessed, using the EIT. Outcomes measures: Reported EIT data of regional ventilation distribution, values of oxygenation and carbon dioxide elimination during the application of supra- and subglottic JV via jet laryngoscope and LaserJet catheter in patients undergoing laryngo-tracheal surgery. The purpose of this study is to investigate the influence of supraglottic and subglottic JV compared to standardized, controlled mask ventilation on measurements of pulmonary regional ventilation distribution by EIT, blood gas analyses and serological biomarkers.
