Comparison of Intubation With Direct Laryngoscopy or Videolaryngoscopy in an Hemoptysis Simulated Situation on Human Cadaver Embalmed With Thiel's Method

2019-09-18 03:27:53 | BioPortfolio


Our study first aims to develope a realistic cadaver model of hemoptysis based on Thiel's embalmed cadavers. Secondly, participants will intubate the hemoptysis cadaver model with (a) the direct laryngoscopy with MacIntosh blade, (b) the videolaryngoscopy with McGrath XBlade and (c) the videolaryngoscopy with McGrath XBlade and a suction advance before the optic of the camera. We hypothesis that, in simulated hemoptysis on the Thiel's embalmed cadaver, the rate of failed intubation at first try will be different depending on the laryngoscope used.


For the simulation of hemoptysis, we will need to use the Thiel's embalmed cadaver, who's realism is established, create a synthetic form of blood resembling real blood by its viscosity and color for the simulation and elaborate the dynamic interface of the simulation of hemoptysis. The quantity and way of administration of the blood through the trachea will be tested to obtain a realistic hemoptysis as seen in supraglottic.

For the simulation, we will compare the efficiency of intubation, judged by the failure rate of intubation on first try, for (a) the direct laryngoscopy with MacIntosh blade, (b) the videolaryngoscopy with McGrath XBlade and (c) the videolaryngoscopy with McGrath XBlade with the suction advanced before the camera. We will also measure the time to intubation, the failure rate of intubation, the suction use and the difficulty of intubation as reported by the participants.

Medical and Biotech [MESH] Definitions

Examination, therapy or surgery of the interior of the larynx performed with a specially designed endoscope.

The removal of secretions, gas or fluid from hollow or tubular organs or cavities by means of a tube and a device that acts on negative pressure.

Removal of localized SUBCUTANEOUS FAT deposits by SUCTION CURETTAGE or blunt CANNULATION in the cosmetic correction of OBESITY and other esthetic contour defects.

Any suction exerted by the mouth; response of the mammalian infant to draw milk from the breast. Includes sucking on inanimate objects. Not to be used for thumb sucking, which is indexed under fingersucking.

Removal of the fetus from the uterus or vagina at or near the end of pregnancy with a metal traction cup that is attached to the fetus' head. Negative pressure is applied and traction is made on a chain passed through the suction tube. (From Stedman, 26th ed & Dorland, 28th ed)
