Comparison of disinfection effect between benzalkonium chloride and povidone iodine in nasotracheal intubation: A randomized trial

Nasotracheal intubation can potentially result in microbial contamination from the upper respiratory tract to the lower respiratory tracts. However, an ideal nasotracheal disinfection method is yet to be determined. Therefore, we compared the disinfection effects between benzalkonium chloride and povidone iodine in nasotracheal intubation.
