Head and neck positioning for out-of-theatre intubation during the COVID-19 pandemic.

The COVID-19 pandemic has brought with it a large number of challenges for healthcare professionals including intubation safety in out-of-theatre environments. An important aspect of this topic is the optimisation of a patient's head and neck position prior to laryngoscopy which can be challenging when a pillow cannot be located. As a result, the authors compared how well the sniffing position (35^o neck flexion and 15^o head extension) could be reached using pillows or other novel head supports. The resulting data demonstrated that a 1-litre pressure bag and two 1-litre saline bags achieved the most accurate position.
