IntroductionThe Covid-19 pandemic has required new protocols for endotracheal intubation mandating cumbersome personal protective equipment and modifications to prior intubation procedures. We assessed the success and complications of endotracheal intubation under such protocols.MethodsWe conducted a prospective study of endotracheal intubation in the emergency department, intensive care unit, or ward between September 11, 2018 and June 11, 2020 at two urban hospitals. Using a standardized form, we included basic demographics, intubation techniques, and success, and pre-specified complications, defined as critical (cardiac arrest or failure to intubate) or non-critical. At both sites, Covid-19 intubation protocols took effect on March 11, 2020, and we compared pre-post patients. The primary outcome was first-pass success without complications. Secondary outcomes included first-pass success and complications. We analysed by descriptive techniques.ResultsOverall, we collected 1534 patients before March 11, 2020 and 227 after; groups were similar in age and sex distribution. Staff endotracheal intubation increased from 37 to 63%. First pass success was 1262/1534 (82.3%) pre versus 195/227 (85.9%) post, for a difference of 3.6% (95% CI - 1.8-8.0%). First pass success without complications was 1116/1534 (72.8%) pre versus 168/227 (74.0%) post, for a difference of 1.3%, (95% CI - 5.2-7.0%). There were 226 complications pre (14.7%) versus 47 (20.7%) post, for a difference of 6.0%. (95% CI 0.6-12.1%).ConclusionsNew pandemic endotracheal intubation protocols did not result in a decrease in first-pass success, or first-pass success without complications.
