Cheap and easy use of a video laryngoscope as a guide for endotracheal intubation in dogs

Background Tracheal intubation is the second most dangerous procedures reflected in the ICU. It includes passing a plastic tube named endotracheal tube (ET) through the vocal cords into the trachea. Errors of this procedure like the placement of ET in the oesophagus or advancing the ET too far into one of the two lungs are life threatening. Objectives This work was designed to provide cheap and quick technique to confirm proper ET tube placement by utilizing simple video laryngoscopy and using dogs as an animal model. Materials and methods This study was conducted on 20 dogs divided into two equal group (n = 10). The first group, in which a semi-flexible video laryngoscope (VLS) fitted with endotracheal tube was introduced and placed into the trachea of the experimental dogs. In the second group, dogs were intubated through soft and flexible video laryngoscope (VLS) fitted with the endotracheal tube. Number and time of the first attempt for introduction of ET were recorded. Results The number of attempts was significantly (P
