Various airway management devices and techniques have been revised and recommended in COVID. In India, during the first wave (April 2020 to November 2020), the strategy included consultant-led intubation teams, the use of video laryngoscopes (VLs), and aerosol box. During the second wave (April 2021 to June 2021), the intubation procedures were modified owing to changes in resources, manpower, and some experience gained from the first wave. This retrospective survey aimed to compare the intubation practice in the ICU of our hospital during the first and second waves of COVID.
All adult patients with respiratory failure secondary to COVID, requiring endotracheal intubation (ETI), in ICU were included. Parameters compared were: seniority of intubator (experience >5 years), first attempt success rate [successful attempt: correct endotracheal tube (ETT) placement confirmed by chest movement, capnography, and expired tidal volume of >8 mL/kg; unsuccessful attempt: failure of insertion of ETT under vision, no chest movement and capnography on ventilation, or time >60 s], desaturation during ETI (pulse oximetry <90%), use of VL (King Vision® with disposable channeled blades), and aerosol box.
Data were retrospectively collected from the medical records for comparison (intubation notes). Eighty intubations were performed in the first wave and 264 in the second wave in our ICU. Using desaturation during ETI as a surrogate marker for the airway event, potential predictors of desaturation were compared. The notable difference between the two cohorts was as follows [Figure 1]:

- Team composition: predominance of senior faculty as primary intubator was higher during the first wave when compared with the second wave (70% vs. 40%). The increased participation of junior doctors as primary intubators was due to the massive surge in the number of COVID patients in the second wave of the pandemic.
- The first attempt success rate for ETI was higher in the first wave (85% vs. 70%). The increased number of attempts with higher desaturation episodes observed in the second wave (55% vs. 70%) could be due to the lesser experience of intubator, increased disease severity, and longer duration of NIV support before ETI.
- Use of VLs increased in the second phase (50% vs. 90%). Though the use of VL showed promise when used effectively, most of the intubators during the first wave did not utilize this modality. This could be due to a lack of experience and familiarity with VL. Extensive airway education programs were undertaken in our institute between the two waves of the pandemic which increased its use in the second wave.
- Use of an aerosol box reduced in the second wave (62% vs. 30%) as its use increased the intubation difficulty and time. A meta-analysis by Lim et al. also concluded that intubation time was significantly longer when an aerosol box was used.
This comparison aims to review and refine our airway management practices. This survey throws light on the importance of ongoing training programs and simulation workshops on airway management, which improve the skills of healthcare professionals. Advancement in skills can improve the outcome trajectory of critically ill patients.
