Comparison of Two Ventilation Methods During Endoscopy of the Pharynx, Larynx and Oesophagus

Sponsor: Poitiers University Hospital

Summary

Around 15,000 ENT cancers are diagnosed each year in France. The majority of these cancers will at one time or another require an Endoscopy of the Pharynx, Larynx and Esophagus (Endo-PLE or suspension laryngoscopy). Endoscopies of the Otorhinolaryngeal (ENT) sphere are common procedures. They consist of inserting a rigid laryngoscope through the mouth, allowing full exposure of the laryngeal sphere. For all patients, these endo-PLE are performed in the operating room and require general anesthesia. This surgical procedure is now performed by performing two laryngoscopies. The first is used to maintain good pulmonary oxygenation by introducing an oxygen cannula, the second constitutes the surgical procedure itself. The oxygen cannula is placed through the nasal cavity, directly up to the entrance of the vocal cords. This procedure is not without risk both for the patient (risk of dental breakage and bleeding during laryngoscopy) but also for the surgeon, because the cannula itself can obstruct his vision. It would be possible to do without one of them by setting up high-flow oxygen therapy (HFOT). This device has been widely deployed in continuous care and intensive care units, but is not yet the subject of much research in surgical units. The HFOT consists of oxygen cannulae delivering a mixture of gases at a high flow rate ranging from 20 to 70 liters per minute. The investigator want to evaluate through this study, the feasibility and effectiveness of setting up HFOT during procedures.
