Background: Laryngoscopes are one of the potential mediators of infection transmission due to their blades contact with oral mucous membranes. Using single-use plastic blades is a method of preventing infection transmission. The aim of this study is to compare the efficiency of single-use plastic and reusable metal laryngoscope blades in orotracheal intubation during the rapid- sequence induction of anesthesia Materials and Methods: In this clinical-trial, 310 patients, more than 10 years of age, who were candidates for elective surgery, were selected. After anesthesia induction, orotracheal intubation was done by either single-use plastic or reusable metal blades for patients. Duration of intubation and arterial oxygen saturation were recorded before and after intubation. Data analysis was done using SPSS software. Results: Orotracheal intubation was done successfully in all patients. Mean differences of intubation time from the standard upper limit were 1.42±8.19 and 13.1±4.22 seconds in the plastic and metal blades groups, respectively. Also, the mean of difference in oxygen saturation of the low 90% after intubation were 6.07±2.71 and 7.16±1.21 in plastic and metal blades groups, respectively. Both parameters indicated statistically significant differences. Conclusion: In rapid-sequence induction of anesthesia, by using single-use blades, both intubation time and arterial oxygen saturation drop will increase in comparison with metal blades. This will cause complications such as aspiration in the patients.
