Cetacaine Spray should be applied for approximately one second or
less for normal anesthesia. Only a limited quantity of Cetacaine is
required for anesthesia. Spray in excess of two seconds is
contraindicated. Average expulsion rate of residue from spray, at normal
temperatures, is 200 mg per second.
To apply, insert the Jetco cannula (J-4) firmly onto the protruding plastic
stem on the bottle and press the cannula forward to actuate the spray
valve. The cannula may be removed and reinserted as many times as
required for cleaning, or sterilization, and is autoclavable.
Cetacaine Liquid Apply 200 mg (approximately 6 – 7 drops or 0.2 cc)
with a cotton applicator or directly to tissue. Do not hold the cotton
applicator in position for extended periods of time, since local reactions
to benzoate topical anesthetics are related to the length of time
of application. Liquid in excess of 400 mg (approx. 12 – 14 drops or
0.4 cc) is contraindicated.
*See Cetacaine Liquid Kit instructions for additional directions for application
by Luer-lock syringe and applicator tip.

(13 mm) in length and 3/16 inch (5 mm) in diameter) and spread thinly
and evenly over the application area. Gel in excess of 400 mg (a bead
approximately 1 inch (26 mm) in length and 3/16 inch (5 mm) in diameter)
