Risk of Bacterial Exposure to the Anesthesiologist's Face During Intubation and Extubation

The practice of intubation and extubation is not without risks to the anesthesiologists. Especially, the face of health care worker is the body part most commonly contaminated by splashes and sprays of body fluids. The aim of this study is to determine the incidence of unrecognized exposure to the anesthesiologists' face during endotracheal intubation and extubation. We will perform face shield swab before and after the endotracheal intubation and extubation. All swabs will be cultured for 48 hours and the number of colony forming units before and after the procedures (intubation/extubation) will be compared.

Cohorts and Interventions

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Bacterial growth of face shield swab after the endotracheal extubation	All swab will be cultured for 48 hours and will be reported as no growth or by number of colony forming unit(CFU)s. The number of CFU of post-extubation swab will be compared with that of pre-extubation swab.	Bacterial swab will be performed 5 minutes after the endotracheal extubation (after the confirmation of sufficient spontaneous breathing)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Bacterial growth of face shield swab after the endotracheal intubation	All swab will be cultured for 48 hours and will be reported as no growth or by number of colony forming unit(CFU)s. The number of CFU of post-intubation swab will be compared with that of pre-intubation swab.	Bacterial swab will be performed 5 minutes after the endotracheal extubation (after the confirmation of adequate mechanical ventilation)
