Improving the C-MAC video laryngoscopic view when applying cricoid pressure by allowing access of assistant to the video screen.

摘要: Cricoid pressure, as part of rapid sequence induction, may on occasion worsen laryngoscopic views and intubating conditions. We investigated whether allowing the assistant applying cricoid pressure to view video laryngoscope screen would improve compared when they were blinded screen. Laryngoscopy using C-MAC was performed in 51 patients undergoing elective general anaesthesia. Photographs recorded sequentially under following conditions: A) by an unable see monitor, B) optimised able monitor. These photographs analysed offline assessors photo obtained with or non-blinded application. Subjectively, 41% improved screen, those The unchanged 45%, but initially worsened 14%. findings suggest that assistants a is used should have access image, must also respond requests for change from person performing intubation.
