Does position of the patient adversely affect successful intubation whilst wearing CBRN-PPE?

Abstract Introduction Following a CBRN incident attending medical personnel will be required to instigate life saving airway interventions whilst wearing CBRN-PPE. CBRN-PPE is known to adversely affect fine motor skill but little is known about whether the position of the patient compounds this problem. Methods Seventy-five clinicians were recruited and performed intubation and insertion of a LMA in to a manikin whilst wearing CBRN-PPE. Both skills were completed twice with the manikin positioned on a bench and once on the floor. Following completion of the study 25 participants (a minimum of 2 participants from each professional group) were interviewed to ascertain their experiences. The recruitment of a non-homogenous group allowed for subgroup analysis with regards the potential impact of professional background on skill performance. Results 9.33% first attempts at intubation at waist height ended in failure but this reduced to 4% on the second attempt. This improvement was reversed with the manikin on the floor where the failure rate was 26.67%. Intubation on the floor took significantly longer to perform, being 45.9 s slower than the first attempt at intubation in the optimal position [95% CI (30.7 s, 61.1 s); p p p  = 0.231) and faster than the first attempt at waist height (by 4.8 s [95% CI (3.4 s, 6.1 s); p Conclusion the position of the patient is likely to be an independent factor when choosing to either intubate or insert a LMA whilst wearing the current NHS CBRN-PPE.
