What may be used to anesthetize the skin and neck structures prior to a cricothyroidotomy?

Lidocaine is commonly used to anesthetize skin and neck structures prior to invasive procedures like cricothyroidotomy because it is a local anesthetic that numbs the area effectively. Its rapid onset and relatively short duration of action make it ideal for procedures that require quick pain relief. By applying lidocaine to the skin before making an incision, the discomfort and pain associated with the procedure can be minimized, making it easier for the medical professional to perform the cricothyroidotomy safely and effectively.

Local anesthetics like lidocaine work by blocking nerve signals in the area where they are applied, ensuring that the patient does not feel pain during the procedure. In contrast, Novocaine is less commonly used in modern practice for this kind of application. Adrenaline is a vasoconstrictor that may be used in conjunction with anesthetics to prolong their effect and reduce bleeding but does not serve as an anesthetic on its own. Vaseline, while it can serve various purposes like creating a barrier or lubricating skin, does not have anesthetic properties and would not alleviate pain.
