I rank Tetracaine 30 on my list of 33 drugs.
We use Tetracaine prior to insertion of Morgan lenses in patients age 6 years and older who have sustained an exposure injury to the eye(s), (i.e. dry or liquid chemical).
The drops numb the eye and make it easier for the patient to tolerate the Morgan Lens.
Here is our Morgan Lens procedure:
· Explain procedure to patient and give rationale.
· Unless contraindicated*, instill one or two drops of Tetracaine.
· Instruct patient not to touch/rub eye(s).
· Spike IV bag and attach/flush tubing, connect Morgan Lens, maintain sterile environment of Morgan Lens.
· Have the patient look down, insert the Morgan Lens under the upper lid, then have the patient look up, retract lower lid and allow lens to drop into place.
· Begin flow rate at wide open and maintain this rate per patient tolerance. Have plenty of towels or chux to absorb flow.
Tetracaine is a nice little drug, but it has been years since I have used a Morgan Lens. When I worked more regularly in the city and dealt with more patients who had been maced or pepper-sprayed, I had more occasion to use the Morgan Lens, although many times we just irrigated the eyes with the IV tubing, as ift takes a high-level of cooperation for a patient to accept a Morgan Lens in their eye.
Nice to have Tetracaine in the kit, but I can do without it if I have to.
