The oesophagus is not exactly posterior to the cricoid, and thus the maneuver is unreliable in producing midline esophageal compression. The efficacy of cricoid pressure has been called into question and it may even increase the risk of regurgitation / aspiration or failed intubation owing to flexion distortion of the observed pharyngeal / tracheal anatomy. The video shows only single-handed Sellick's manoeuvre which may be rendered ineffective by flexion and / or torsion of the neck as the head falls deeper into the pillow as cricoid pressure is applied Dual-handed Sellick's manoeuvre is considered far safer. It requires the assistant to place one hand posterior to the patient's neck thereby supporting it, preventing lateral or anterio-posterior flexion, and then the other hand applying cricoid pressure. Experienced practitioners may safely use the dual -handed technique with just one anaesthetist and one ODP. If a second anaesthetist or ODP is involved then demarcation of roles in the tripartite procedure must adequately be established beforehand.

Good video, although there is no indication as to when the cricoid pressure should be increased from 10-30N. I would normally ask the patient to keep their eyes open and increase the pressure as they start to close.

Did the patient just blink? 6:52

Thank you

Thanks a lot

Thank you!

Thiopentone sodium still used these days???

Thank you
