Abstract:
Nasotracheal intubation is the preferred route for general anesthesia maintenance in patients undergoing maxillofacial surgery or dental procedures. However, compression of the tracheal tube may cause superficial necrosis of the nasal wing and deformation of the external nose. Thus, proper fixation of the tracheal tube during nasotracheal intubation is important for the patient's safety as well as that of the medical staff. Recently, a nasotracheal tube support device has been developed; thus, in this study, the aim was to present and describe the Sverzut nasotracheal tube support device and discuss the advantages of its use during nasal intubation in cervicomaxillofacial surgery. Findings from this study show that the Sverzut nasotracheal tube support device can contribute to the stabilization of the nasotracheal tube and all its connectors, aiding in the maintenance of the airway patency and minimizing the complications related to this type of intubation.

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
