Laryngoscope Prototype Tested Against the Traditional Macintosh Blade
Not Provided
The primary objective is to evaluate a knewly developed blade (for intubating patients about to undergo surgery) and compare it to the traditional Macintosh blade

Intubation of patiens can be difficult, even impossible. It can result in different complications as damage to the teeth, lacerations of the mucosa, bleeding, fractures/luxations, hypoxia, hypercapnia, reflex bradycardia and in worst case braindamage and death.

The more difficult the intubation is the more frequent complicationrate. We believe to have developed a laryngoscopeblade that hopefully eases the intubationproces and thereby reduces the complicationrisk.

The patients included in this study is patients who are undergoing elective surgery requering intubation.
