Six box-and-whisker plots illustrating intubation times in seconds for six scenarios involving McGrath MAC, AIRWAY SCOPE, and AceScope video laryngoscope in normal airway and cervical immobilization models. Scenario (1) intubation with McGrath MAC in a normal airway model, (2) intubation with McGrath MAC in a cervical immobilization model, (3) intubation with AIRWAY SCOPE in a normal airway model, (4) intubation with AIRWAY SCOPE in a cervical immobilization model, (5) tracheal intubation using AceScope in a normal airway model, and (6) tracheal intubation using AceScope in a cervical immobilization model. In the normal airway model, significant differences were observed between McGrath MAC and AIRWAY SCOPE (p < 0.05) and AIRWAY SCOPE and AceScope (p < 0.05), but not between McGrath MAC and AceScope (p > 0.05). In the cervical spine immobilization model, significant differences in intubation time were found among all three groups (McGrath MAC vs. AIRWAY SCOPE: p < 0.05, McGrath MAC vs. AceScope: p < 0.05, AIRWAY SCOPE vs. AceScope: p < 0.05)
