Thank you for your attention to this matter.ĭivision Chief, Non-Operating Room Anesthesia There are other Macintosh blades available that do not have this design. This is a patient safety issue that warrants attention. This hook helps in securing the blade to the handle, but has the potential to dig into the soft tissue of the lower lip area.
The blade has an overhang or hook at the fulcrum where it attaches and engages at the handle (figure 3).
The reason for presenting this incident is to bring to your attention the design of this particular laryngoscope blade, BritePro Solo™ from Flexicare, Inc. However, injuries with significant bleeding are possible in patients on anticoagulation. 2 Old age was not found to be a significant risk factor in that study except in injuries to the oral mucosa.

1 In another review study, soft tissue trauma was observed in 52% of patients after direct laryngoscopy with Mac 3 or 4 blade with maximum injuries to the tongue (36.3%), followed by lower lip injuries (22.3%). Tongue injuries were found to have the highest incidence in a study on the electrophysiology population in a large academic center. However, we had no problem intubating this gentleman. Soft tissue injuries during laryngoscopy and tracheal intubation are common especially in a difficult airway.
